2019 Global Status Report for Buildings and Construction
Towards a zero-emissions, efficient and resilient buildings and construction sector

Foreword
Decarbonising the buildings and construction sector is critical to achieve the Paris Agreement
commitment and the United Nations (UN) Sustainable Developments Goals (SDGs): responsible foralmost 40% of energy- and process-related emissions, taking climate action in buildings andconstruction is among the most cost-effective. Yet, this 2019 Global Status Report on buildings and Page | 3
construction tells us that the sector is not on track with the level of climate action necessary. On
the contrary, final energy demand in buildings in 2018 rose 1% from 2017, and 7% from 2010.
These findings stand in stark contrast with the 2019 Emissions Gap Report, which states that wewill have to cut almost 8% of emissions each year from 2020, and are confirmed by theInternational Energy Agency (IEA) World Energy Outlook 2019, which found that in 2018 the rateof improvement in energy intensity had slowed to 1.2% – less than half the average rate since 2010.
Both reports underline the need for urgent action by policy makers and investors. To meet theSDGs and the IEA Sustainable Development Scenario, we need to reverse the trend and make aconcerted effort to decarbonise and enhance energy efficiency in buildings at a rate of 3% a year.
In 2020, Nationally Determined Contributions (NDCs) under the Paris Agreement are due forrevision – an opportunity that cannot be missed to ramp up ambition in the buildings andconstruction sector. The 2018 Global Status Report on buildings and construction found that a totalof 136 countries have mentioned buildings in their NDCs, yet few have specified the actions they
will use to reduce emissions. Therefore, in their new NDCs, nations must prioritise actions todecarbonise this essential sector. This means switching to renewable energy sources. It means
improving building design. It means being more efficient in heating, cooling, ventilation, appliancesand equipment. It means using nature-based solutions and approaches that look at buildings within
their ecosystem, the city.
The report also tells us that the building stock is set to double by 2050, which presents anotherimportant opportunity not to be missed. In making good on SDG 11 with its provision for affordable
and adequate housing for all, we need to make sure we promote clean solutions and innovations
to make buildings future-proof. In line with SDG 7, we have to double our efforts on energy
efficiency to bring gains of at least 3% per year.
Such efforts must be supported through investments in energy efficiency; but here also, thenumbers show that we are headed in the wrong direction: investment in buildings sector energy
efficiency flattened in 2018 instead of showing the growth needed. In September, at the UN
Secretary General’s Climate Summit, countries as well as the private sector made commitments toa zero-carbon buildings sector, and the goal of mobilising USD 1 trillion in “Paris-compliant”
building investments in developing countries by 2030 was set. At the same time, the Net-Zero Asset
Owner Alliance was founded with the world’s largest pension funds and insurers – responsible fordirecting more than USD 2.4 trillion in investments – committed to carbon-neutral investment
portfolios by 2050.
These are signs of hope. And change is in the works. This report provides examples of country, cityand private sector actions, of how the buildings and construction sector is reforming. Through thisGlobal Status Report series, we are keeping an eye on progress made. And through another joint
product – a series of regional roadmaps – we are working with experts and policy makers in
defining their regionally appropriate actions across eight priority action areas to put the sector on
track: urban planning; new buildings; retrofits for existing buildings; building operations;appliances, lighting, cooking and systems; materials; resilience of buildings; and clean energy.
These roadmaps and actions can then be further adapted nationally.

It is well within the realm of possibility for the buildings and construction sector to deliver its full
mitigation potential and help the world achieve its climate and sustainable development goals.
Together, we can build for the future.

Towards a zero-emissions, efficient and resilient buildings and construction sector

Executive Summary
The buildings and construction sector accounted for 36% of final energy use and 39% of energy
and process-related carbon dioxide (CO2) emissions in 2018, 11% of which resulted frommanufacturing building materials and products such as steel, cement and glass. This year’s Global
Status Report provides an update on drivers of CO2 emissions and energy demand globally since Page | 92017, along with examples of policies, technologies and investments that support low-carbon
building stocks.
The key global buildings sector trends are:
•

•

•

•

Global buildings sector emissions increased 2% from 2017 to 2018, to reach a record high,while final energy demand rose 1% from 2017 and 7% from 2010.
Increases were driven by strong floor area and population expansions. While efficiency
improvements continued to be made, they were not adequate to outpace demand growth.
2020 is a key year for countries to enhance their Nationally Determined Contributions(NDCs), especially concerning further actions to address energy use and emissions including
embodied emissions in the buildings and construction sector.
Countries are innovating and implementing measures to improve efficiency and reduce
emissions from their building stock. As sharing effective measures globally would amplify
their impact, regional roadmaps are being developed for this purpose.

Global building stock emissions continue to rise
In 2018, global emissions from buildings increased 2% for the second consecutive year to
9.7 gigatonnes of carbon dioxide (GtCO2), suggesting a change in the trend from 2013 to 2016,
when emissions had been levelling off. Growth was driven by strong floor space and population
expansions that led to a 1% increase in energy consumption to around 125 exajoules (EJ), or 36%
of global energy use.

2019 Global Status Report for Buildings and Construction
Towards a zero-emissions, efficient and resilient buildings and construction sector

A major source of rising energy use and emissions by the global building stock is electricity, the useof which has increased more than 19% since 2010, generated mainly from coal and natural gas.
This indicates how crucial it is to make clean and renewable sources of energy accessible, and touse passive and low-energy designs more widely in building construction.
Page | 10

From 2017 to 2018, energy intensity continued to improve for space heating (-2%) and lighting(-1.4%), but increased for space cooling (+2.7%) and remained steady for water heating, cooking
and appliances. At an 8% increase in 2018, space cooling became the fastest-growing use of energy
in buildings since 2010, though it accounted for only a small portion of total demand at 6%.

2020 NDC revisions are a new opportunity to reduce buildings
sector emissions
As part of their plans to limit greenhouse gas (GHG) emissions, 184 countries have contributed
NDCs under the United Nations Framework Convention on Climate Change (UNFCCC). Althoughmost countries (136) mention buildings in their NDCs, few detail explicit actions to address
emissions within the buildings sector. In the next round of NDCs, covering 2020 to 2025, further
focus is needed on actions to mitigate building emissions through switching to low-carbon andrenewable energy sources, and greater attention should be paid to low-carbon building materials,
building envelope improvements, nature-based solutions, and equipment and system efficiency.
These efforts will require higher investments than the USD 139 billion of 2018 – which was a 2%
drop from the previous year. To tackle emissions and reduce energy intensities in the buildings andconstruction sector, governments, companies and private citizens must raise investments inefficiency adequately to offset growth.

New policies lead the way forward
Although greater ambition is needed, policy makers, designers, builders and other participants inthe buildings and construction value chain globally are undertaking activities to decarbonise theglobal building stock and improve its energy performance.
In a number of countries, building codes are being introduced for the first time or are being
strengthened, for example in India through the Eco-Niwas Samhita India’s first energy
conservation code for the residential sector, and in Rwanda through the Green Building
Minimum Compliance System. Policies regulating the energy performance of new buildings
are a powerful means to address future emissions growth.
•
Building owners continue to adopt advanced certifications for high energy performance orlow- and zero-carbon buildings, which stimulates improvements in both the new andexisting building stock. The World Green Building Council offers support for such actions
through its Net Zero Carbon Buildings Commitment that is being developed among its
partners.
•
Investors are establishing dedicated products and funding schemes for low-energy and lowcarbon buildings across the world. For example, the EU Green Tagging strategy that sets
rules for European green financing is the first to include recommendations for net-zeroenergy buildings (nZEBs) and green renovation.
These activities to enact regulations and enable greater market adoption of low-energy buildings
are encouraging signs of efforts to curb future energy demand and emissions.
•2019 Global Status Report for Buildings and Construction
Towards a zero-emissions, efficient and resilient buildings and construction sector

Some countries have also established strategies to work towards achieving a net-zero-carbon
building stock by 2050 or earlier. For example, Japan and Canada are developing new policies toachieve net-zero and net-zero-ready standards for buildings by 2030. As more countries prepare
their NDCs, more ambitious strategies to address existing building stocks will be put forward.
The Global Alliance for Buildings and Construction (GlobalABC) and the International Energy
Agency (IEA), in collaboration with regional members and stakeholders, are developing Regional Page | 11
Roadmaps for Latin America, Africa and Asia to forge pathways towards efficient and resilient zeroemissions buildings and construction sectors. The roadmaps:
•

•

•

•

Highlight priority actions for each region in eight key areas: urban planning; new buildings;
existing building retrofits; building operations; systems; materials; resilience; and clean
energy.
Are being developed through consultations, workshops and webinars held across the three
regions to gather insights and opinions from regional, national and local stakeholders on
the targets and timelines for delivering an energy-efficient, low-carbon building stock.
Are regionally owned living documents that will be shared by the end of 2019 and continue
to be developed throughout 2020.
Support activities such as national alliances that unite local construction value chains toenable the development and implementation of national strategies for zero-net-energy and-emissions buildings.

2019 Global Status Report for Buildings and Construction
Towards a zero-emissions, efficient and resilient buildings and construction sector

Global status
The buildings and construction sector globally is showing an increase in both emissions and energyuse, limited progress on new and existing policies, and a further slowdown in energy-efficiency
investment growth. More action is therefore needed to curb emissions and deliver a low-carbon,
Page | 12 sustainable built environment.

Energy and emissions in the buildings and construction sector
Building construction and operations accounted for the largest share of both global final energyuse (36%) and energy-related CO2 emissions (39%) in 2018 (Figure 2).

Key message • The buildings and construction sector should be a primary target for GHG emissions
mitigation efforts, as it accounted for 36% of final energy use and 39% of energy- and process-related
emissions in 2018.

Energy trends
Global final energy consumption in buildings in 2018 increased 1% from 2017, and by more than 8
EJ (about 7%) since 2010 (Figure 3). While strong growth in the main buildings sector resulted fromfloor space and population expansion outpacing energy efficiency gains, floor area growthcontinues to decouple from energy demand, with floor area in 2018 having increased 3% from2017 and 23% since 2010.
From 2010 to 2018, global electricity use in buildings rose by over 6.5 EJ, or 19%. Emissions, which
result from the fuel sources used for electricity generation and still include high levels of coal,especially in emerging economies, also rose in 2018. Continued decarbonisation of the electricity
supply is therefore needed to transition to clean-energy, low-carbon buildings. Also during
2010-18, renewable energy became the fastest-growing energy source for buildings, with its use
increasing 21% (up 3% during 2017-18 alone). Natural gas use rose 8% during the same period,
meeting new demand as well as displacing coal use, which dropped by almost 10% globally during
2010-18 (-2% from 2017 to 2018).

Notes: Energy data are not normalised for weather, so yearly energy changes may be due to climatic differences. Biomass (traditional)
refers to conventional solid biomass (e.g. charcoal and forest or agricultural resources) used in inefficient heating and cooking
equipment. Renewables includes solar thermal technologies as well as modern biomass resources (e.g. pellets and biogas).

Key message • Global growth in buildings sector fuel use has concentrated on electricity, natural gas andtraditional biomass since 2010, and higher electricity use in recent years has further increased CO2
emissions.

Globally, greater end-use energy consumption due to significantly higher electricity use since2010 for space cooling, appliances and hot water, is resulting in increased emissions (Figures 4
and 5). Space cooling demand rose more than 33% during 2010-18 and by 5% in 2017-18, whileenergy demand for appliances in 2018 increased by 18% since 2010 and for water heating by
11%. At the same time, space heating demand decreased 1% from 2010, though it has remained
stable for the past five years at one-third of total global energy demand in buildings.

Key message • Although space heating, water heating and cooking continue to be the primary end-use
energy demands in the buildings sector globally, the fastest-growing end uses are still space cooling,
appliances and other plug loads.

Page | 132019 Global Status Report for Buildings and Construction
Towards a zero-emissions, efficient and resilient buildings and construction sector

From 2010 to 2018, changes in buildings sector energy intensity per unit of floor area (as a proxyfor energy efficiency) show that the greatest improvements (i.e. reductions) were in global
average space heating (-20%) and lighting (-17%) (Figure 5). Light-emitting diodes (LEDs)
continue to be important in reducing energy consumption for lighting as floor area increases andfalling consumption for space heating indicates that building envelopes have improved.
Page | 14 However, as floor area has been expanding rapidly in hot countries, cooling demand is increasing.
As better building envelopes are crucial to reduce energy use for heating and cooling, building
codes must remain a policy priority along with technology efficiency improvements.

equipment.

Technology Perspectives, buildings model, www.iea.org/buildings.

Key message • Owing to technological improvements, overall reductions have been made in energy
intensity for space heating, lighting, appliances, cooking and water heating. However, space coolingenergy intensity has increased as a result of greater cooling demand in hot regions.

Factors influencing global buildings sector energy use include changes in population, floor area,
energy service demand (e.g. more household appliances and cooling equipment), variations inclimate and how buildings are constructed and used. Those that have contributed most to higher
energy demand since 2010 are floor area, population and building use, while improvements inbuilding envelopes (e.g. better insulation and windows) and in the performance of building
energy systems (e.g. heating, cooling and ventilation) and components (e.g. cooking equipment)
have helped to offset energy demand growth (Figure 6). Nevertheless, total energy demand inbuildings continues to increase and greater investments in efficiency and passive design
strategies are needed to limit demand and reduce energy intensity.
Final energy consumption in residential buildings made up more than 70% of the global total in 2018,with growth resulting primarily from floor area and population increases, while floor area alone
remains the main driver of higher consumption in non-residential buildings (Figure 7). Consumption
in residential buildings rose more than 5 EJ during 2010-18, and 3 EJ in non-residential buildings.
Growth in residential demand continues to reflect population and floor area increases as well as
development in emerging economies, along with a continued shift away from the traditional use of
biomass towards modern fuels (e.g. electricity, liquefied petroleum gas and natural gas).

Key message • Energy-efficient building systems and envelopes continue to limit growth in both residential
and non-residential building energy use, though continued effort is needed to reduce energy intensity.

GHG emissions trends
In a reversal of the previous five years, buildings sector emissions appear to have risen to 9.7 GtCO2
in 2018 – an increase of 2% since 2017, and 7% higher than in 2010. Buildings represent 28% of
global energy-related CO2 emissions (39% when construction industry emissions are included).
Indirect emissions (i.e. from power generation for electricity and commercial heat) account for thelargest share of energy-related CO2 emissions in the buildings sector, representing around 68% of
total buildings-related emissions from energy consumption in 2018 (Figures 8 and 9). The increases
in emissions in 2016 and 2017 correspond with floor area and population expansions as well as2019 Global Status Report for Buildings and Construction

Key message • In 2018, global buildings sector emissions increased for the second consecutive year, risingby 2% from 2017 to a record high of 9.7 GtCO2. This growth resulted from increases in floor space anddemand for electricity, which is still primarily fossil fuel-generated.

2019 Global Status Report for Buildings and Construction
Towards a zero-emissions, efficient and resilient buildings and construction sector

Sustainable buildings and construction policies
By 2020, countries are requested to communicate their new or updated nationally determined
contributions (NDCs) setting out their efforts to reduce national emissions and adapt to theimpacts of climate change. 2020 is therefore a key year for countries to enhance their NDCs andcommit to more aspirational targets.
Page | 17
In addition to NDCs, the coverage and strength of energy performance building codes andcertification policies have continued to expand, and in 2018 several countries with updated codes
adopted meaningful improvements that should reduce buildings sector energy demand growth,
especially for heating and cooling, and make buildings and construction more sustainable.

Nationally Determined Contributions (NDCs)
Reporting on NDCs is an international process during which countries announce their national-levelcommitments to reduce emissions to limit the rise in average global temperature to less than two
degrees Celsius (°C) above pre-industrial levels by 2100, as set out in the Paris Agreement.
The 24th Conference of the Parties (COP24) in Katowice, Poland, presented the Katowice Climate
Package that sets out the procedures and mechanisms to operationalise the Paris Agreement.
Within the package is guidance on communicating efforts to adapt to climate impacts; atransparency framework for efforts on climate change; a process for conducting a global stocktakeof overall progress towards the aims of the Paris Agreement; and directions for assessing progresson technology development and transfer. The package also contains directions for a further roundof NDCs to be submitted by 2025.
To ensure comparability across all NDCs, it outlines how to develop mitigation goals and activities,
specifically covering:
mitigation co-benefits•
capacity-building support to help developing countries produce their NDCs•
a common time frame for communicating NDCs•
negative impacts of response measures on certain countries and sectors•
modalities for operating and using the public NDC registry.
To date, most countries (184) and the European Union have submitted NDCs, and many countries(136) mention buildings, although most NDCs still do not include explicit actions to address
buildings sector energy use and emissions (Map 1). Seven countries updated their NDCs in 2018-19,
and the Marshall Islands submitted their second NDC in 2019.
•

To help countries address buildings-related emissions, GlobalABC has developed guidance on how
to include buildings in the NDCs through mapping, prioritising, implementing and monitoring(UNEP, 2018). GlobalABC supports ambitious buildings sector climate actions, defined as those thatwill move the sector towards zero emissions by 2050 while increasing the built environment’s
resilience and adaptive capacity.

Source: Adapted from UNFCCC (2019), Interim NDC Registry.

Key message • Most current NDCs do not explicitly cover buildings sector emissions.

NDCs submitted in 2018-19 focus on improving building performance codes and standards, fuelconservation and phasing out inefficient products and equipment (Box 1).
Box 1 •

2018-19 NDC updates related to buildings and construction

KuwaitIn May 2018, the Government of Kuwait submitted its NDC that proposes a set of large projects aimed at reducing
the GHG emissions of the energy sector. As part of its climate commitment, the country has developed legal andregulatory instruments, including an Environmental Protection Law in which Article 11 highlights the government’s
interest in improving energy efficiency in the buildings sector through the use of better materials and equipment(light bulbs, air conditioning, retrofitting, etc.).

Oman
Oman intends to reduce its GHG emissions by 2% during 2020-30. The government plans to adopt various
mitigation measures for the energy, industrial processes and waste sectors, including promoting energy efficiency
and reducing the use of HCFCs (hydrochlorofluorocarbons) in foam and refrigeration. Oman has also requested
special support for funding, capacity-building and technology transfer to effect further action on sustainablebuildings.

San Marino
Despite contributing only 0.00052% of global emissions, San Marino has committed to reduce its GHG emissions
to 20% below the 2005 level by 2030. Since 2008, San Marino has deployed environmental policies to improvebuildings sector energy efficiency, promote renewable energy through solar photovoltaic (PV) and reduce energy
consumption. Additional efforts on waste management, solvent emissions and new technologies have been madein recent years.

2019 Global Status Report for Buildings and Construction
Towards a zero-emissions, efficient and resilient buildings and construction sector

Suriname
In February 2019, Suriname submitted its NDC that focuses on promoting further actions for forest management
and renewable energy. The government prepared a National Energy Plan 2013-2033 that outlines PV, waste-toenergy, micro-hydro power, wind, and biomass initiatives. The plan also includes a national energy efficiency
programme to support efficient appliances, energy-saving in buildings and consumer awareness in electricity
consumption. Additional climate change actions have been taken through the National Climate Change Policy,
Strategy and Action Plan (NCCPSAP) that provides the legislative and administrative framework for low-carbon
development in the country.

Uzbekistan
Uzbekistan intends to reduce its specific carbon emissions per unit of gross domestic product (GDP) to 10% below
the 2010 level by 2030. The efforts of the country cover three main pillars: energy efficiency; research, educationand training; and control and monitoring of GHG emissions. Specific measures to improve energy efficiency inbuildings to reduce the country’s overall energy consumption and to develop financial schemes to support theseactions are key measures within the energy efficiency pillar.

Of the 136 NDCs that now reference the buildings sector, most do not have specific targets orpolicy actions (Figure 10). While existing policies and NDCs covered more than 50% of buildingsrelated CO2 emissions as of 2018, 1 if committed NDCs were to become policy, the coverage would
increase to more than 60%.

Building energy codes
Building energy codes, or standards, are requirements set by a jurisdiction (national or subnational)
that focus on reducing the amount of energy used for a specific end use or building component. In
2018, 73 countries had mandatory or voluntary building energy codes or were developing them.

Building energy codes by jurisdiction, 2018-19

IEA (2019). All rights reserved.
Source: Adapted from IEA (2019c), Energy efficiency policies: Buildings, www.iea.org/topics/energyefficiency/policies/buildings.

Key message • Although many developing economies still do not have mandatory building energy codes
despite high construction rates, changes are beginning in regions that have traditionally not had codes,
such as sub-Saharan Africa.

Building energy codes play an important role in setting standards for building construction that will
reduce the long-term energy demands of the buildings sector. With mandatory and progressive
codes, energy use can be better managed as floor space expands, and progressive codes can respondto changes in legislation and the availability of cost-effective technologies. For maximum impact, it isessential that a building code be strong, be improved progressively over time and be implemented
effectively. It is also advisable to move towards mandatory codes for both residential and nonresidential buildings.
Of the 73 countries with codes, 41 have mandatory residential building codes and 51 have mandatory
non-residential codes; 4 have voluntary residential codes while 12 have voluntary non-residential
codes; and 8 more are in the process of developing building codes. Greater coverage, adoption andstrength are needed to continue improving the energy performance of new buildings and major
refurbishments.
There is still considerable need for countries and subnational jurisdictions to develop and effectively
implement building energy codes to reduce future energy demand and avoid expensive retrofits
later. There are signs, however, that such codes are being considered by a number of countries incentral Africa and Central America.

US code updates
Many US states and cities are adopting more stringent residential and non-residential building energy codes. Statesthat have updated their building energy codes include California, Florida, Idaho, Illinois, Utah, Vermont andWisconsin, in addition to cities such as Chicago.

Eco-Niwas Samhita (Part 1: Building Envelope), India
India’s Ministry of Power launched ECO Niwas Samhita, an Energy Conservation Building Code for Residential
Buildings (ECBC-R) to promote the energy-efficient design and construction of homes, apartments and townships.
Given the pace at which India’s building stock is expanding, it is a landmark policy that introduces energy efficiency
into the buildings sector and is relevant for all involved in the construction process. The code is being implemented
at the state level with national support.

Rwanda Green Building Minimum Compliance System, Rwanda
The Green Building Minimum Compliance System is point-based and applies to new commercial buildings, publicbuildings, assembly buildings, health facilities and educational buildings to help owners and developers choose
indicators based on building type, usage and associated benefits. The system identifies 29 indicators for the basic
green features any building should have, such as appropriate orientation, daylighting, natural ventilation, rainwater
harvesting, efficient plumbing fixtures, low-impact refrigerants, greenery protection and safe paints.

Building energy certification
Building energy certification involves programmes and policies that evaluate the performance of abuilding and its energy service systems. Certification may focus on rating a building’s operational or
expected (notional) energy use, and can be voluntary or mandatory for all or part of a particularbuildings sector. The aim of energy performance certification for buildings is to provide information
to consumers about their buildings and to gradually create a market for more efficient buildings.

Key message • Certification programmes are still primarily voluntary in most countries.

2019 Global Status Report for Buildings and Construction
Towards a zero-emissions, efficient and resilient buildings and construction sector

As of 2018, 85 countries had adopted building energy performance certification programmes(Map 3), and several countries and subnational jurisdictions also updated their building energy
certification policies in 2017-18 (see Box 3). The use of certification programmes is growing, withvoluntary certification for high-end buildings becoming a popular means of adding value, but there
is still a lack of large-scale adoption of full, mandatory certification programmes outside the European
Page | 22 Union and Australia. This means that tracking building energy performance over time andsubsequently disclosing the information is still limited.

Examples of building energy certifications, ratings and labels

Green buildings for financial institutions, global
Property developers are beginning to benefit from financing offered by forward-thinking banks that encourage theconstruction sector to design better-performing buildings. These banks offer financing to developers for projects thatare certified green at the design stage through EDGE and other leading certification systems. In turn, banks benefit
from owning a portfolio of green assets with greater value and less risk. In Colombia, there were no green-certified
homes before banking incentives were introduced, but the market was transformed when the International FinanceCorporation (IFC) launched EDGE and collaborated with local financial institutions and the government. Now,
hundreds of residential (as well as commercial) buildings are being certified as green.

Energy Efficiency in Municipalities Project, Ukraine
More than 50 municipalities in Ukraine are participating in a benchmarking system for the energy performance of
their buildings. It comprises a dataset of about 2 000 municipal buildings and compares their energy performance,
allowing each municipality to better plan and prioritise renovation activities.

Building Efficiency Accelerator (BEA) project, Dubai, United Arab Emirates
Dubai is the first and only city in the Middle East committed to the BEA project, aiming to accelerate implementationof building efficiency policies and programmes and to double the global energy efficiency improvement rate by 2030.
A demonstration project was conducted to benchmark the energy performance of existing hotels, schools andshopping malls. The project covers 121 UAE properties, 103 of which are in Dubai.

Green Building Councils’ Net-Zero Certification, global
Green building rating tools increase awareness and uptake of green building measures, encouraging a holistic
approach to sustainability in the built environment and acknowledging performance beyond local regulatory
requirements. To recognise buildings that are responding to the climate crisis, Green Building Councils (GBCs) globally
have been developing or adapting tools to certify net-zero-carbon buildings. Under the WorldGBC's Advancing Net
Zero project, these tools are developed within a framework of common principles to ensure alignment in theirapproach while applying locally specific criteria such as energy efficiency standards or inclusion of whole lifecycle
emissions. Nine certification schemes and two frameworks have been released so far, including Leadership in Energy
and Environmental Design (LEED) Zero from the US GBC. The performance-based approach ensures that there is afocus on the way buildings actually perform, and flexibility for projects to achieve the same performance standards in
a contextually appropriate way.

WorldGBC’s Net-Zero-Carbon-Buildings Commitment, global
WorldGBC’s Net-Zero-Carbon-Buildings Commitment challenges businesses, organisations, cities, states and regions
to reach net-zero operating emissions in their portfolios by 2030 and to advocate for all buildings to be net-zerocarbon by 2050. It currently has more than 60 signatories from 31 businesses and organisations, including developers,
real estate investors and property funds, manufacturers and global design firms. Six states and regions are involved,
as well as 26 cities including London, Tokyo and New York.

Investment and financing for sustainable buildings
Total energy efficiency spending 2 on buildings amounted to USD 139 billion in 2018 (Figure 11), a
decline of 2% from 2017 (IEA, 2019). Driving this deceleration is the slowdown in investment within
the European Union, even though the United States and China continue to invest in more energyefficient building systems. Within Europe, governments have either limited investment expansions Page | 23
(e.g. the United Kingdom and France) or have cut it back (e.g. Germany). In China, by comparison,
overall real estate investment has grown 6% per year since 2015 to over USD 1.8 trillion in 2018.
Chinese investment has been focused largely on residential buildings, with investments in efficiency
rising to USD 27 billion in 2018 – a 33% increase from 2015. In the United States, investments in bothresidential and non-residential construction grew at a rate of 3.8% from 2015 to 2018, to reach USD
1.4 trillion, but the share of investment for improving building energy efficiency is in decline at 2% of
total 2018 investment. The real estate market continues to embrace and invest in green buildings
and green-building rating systems, with their overall Environmental, Social and Governance (ESG)
scores increasing, which is a promising sign for the sector (GRESB, 2019).
The 2018 Global Status Report (IEA and UNEP, 2018) provides further details on past investment
and financing in sustainable buildings.

Key message • Although the buildings sector continues to receive the largest portion of energy efficiency
investments, sums levelled off between 2017 and 2018.

The overall investment trend mirrors slower progress for energy efficiency outcomes, with 2018
marking the third consecutive year in which the energy efficiency improvement rate slowed. An
underlying factor was the static energy efficiency policy environment in 2018, with little progress
made in implementing new efficiency policies or increasing the stringency of existing ones.

Global survey
In the summer of 2019, an online questionnaire was sent to all GlobalABC members requesting
their input for the 2019 Global Status Report, as well as case studies.
Page | 24

The questionnaire provided members the opportunity to highlight their activities in support of lowenergy and low-carbon buildings and cities through actions such as new or improved building codesand standards, building certifications and NDCs. The following sections present insights from theresponses.

Survey findings
The survey received 43 responses from a mixture of civil society organisations (30%), national
governments (28%), the private sector (21%), non-governmental organisations (NGOs) (7%) andothers. Although the majority of countries noted that no updates had been made to their NDCs in2017 or 2018, several had updated their commitments relating to strategies for 2050 on buildings
and construction (see Box 4) and most that responded had begun the 2020 revisions process.
A number of countries identified financing schemes to facilitate investment in low-emissions
buildings through forms of green financing, for example a state grant in Sweden to support lowrent apartments, whereby a higher grant can be received if the building’s energy performance
surpasses the building code. In Senegal, local governments are offering reduced taxes ondevelopment when local materials are used in housing construction.
In 2018 and 2019, building energy codes were updated in three respondent countries: Colombia,
Japan and Senegal. For Colombia, this involved revision of its mandatory local and regional building
energy codes for both residential and non-residential buildings, covering public and transport
spaces for the first time. Japan’s revisions included an update to the national partially mandatory
energy code for both residential and non-residential buildings.
Several countries are considering innovative building codes or expanding existing ones to coverbroader lifecycle emissions beyond energy. For example, Sweden is investigating addressing theenvironmental impact of new buildings by using an environmental certification. Currently in theprocess of revising its CO2 Act, Switzerland is considering introducing a very strict CO2 emissions
cap for existing buildings, which in most cases would result in the banning of fossil fuel-basedheating systems unless the building is very well insulated. Meanwhile, Canada’s codes seek toleverage high-performance technologies and construction practices that are at thecommercialisation stage, and to include more climate change adaptation and resilience measures.
Building energy performance certification remains largely voluntary among respondent countries,
with some exceptions for certain building types (commercial buildings in Tokyo, New York andSingapore, for example) or locations (e.g. both residential and non-residential buildings in theEuropean Union). A range of certification types are being used around the world to indicate
performance, and they are a mix of predicted and measured approaches. Respondents thatrecently updated their certifications include Sweden (2018), which has included mandatory
coverage for all building types, and Medellin, Colombia (2019), which updated its voluntary
coverage for residential and commercial buildings.

Examples of country strategy updates for 2050

Japan
The Japanese government has decided that net-zero or less-than-average energy consumption for new houses andbuildings will be required by 2030 (the zero-energy-building [ZEB]/zero-energy-house [ZEH] policy). Furthermore, thegovernment will require that new houses contribute negative net emissions over their entire lifecycle –i.e. frommaterial production and construction to dismantling and reuse. For existing houses and buildings, the government
will facilitate renovations and energy-efficiency actions. In addition, it will further support innovative technology
development and the wider use of building materials and equipment necessary to bring average energy consumption
in houses and offices to approximately net-zero or less (ZEH/ZEB equivalents) as early as possible in the second halfof this century.

CanadaCanada’s provinces and territories, in consultation with Indigenous peoples, have developed a plan to meet theiremissions reduction targets, grow the economy and build climate resilience. The Government of Canada is working
with provinces and territories to: 1) develop a net-zero-energy-ready building code, with the goal of having provinces
and territories adopt it by 2030; 2) develop a model code for existing buildings to help guide energy-efficiency
improvements during renovations, to be adopted by all provinces and territories; 3) develop tools to support the aimof implementing building energy use labelling by as early as 2019; 4) help provinces and territories expand their efforts
to improve building energy performance through green infrastructure investments; 5) set new standards for heating
equipment and other key technologies; and 6) support Indigenous communities and governments as they improvethe energy efficiency of their buildings.

Argentina
The Argentine Secretariat of Environment and Sustainable Development and the Secretariat of Housing of the Ministryof the Interior, Public Works and Housing, have developed a National Strategy of Sustainable Housing. Its main
objective is to gain an understanding of sustainability in the housing sector, including promoting actions that canchange attitudes among the population, planning and designing buildings considering environmental and climatic
factors, using more efficient construction systems, and gathering a wide range of public and private stakeholders tofurther discuss and promote sustainable housing from a lifecycle perspective.

Germany
In 2019, the German government formed a climate cabinet headed by the chancellor to achieve consensus on a new
package of emissions reduction measures to meet the 2030 targets. The resulting Climate Action Programme 2030
includes a phased CO2 pricing system that will also apply to heating emissions not covered by the EU Emissions Trading
System (ETS) and thereby encourage ongoing energy efficiency efforts. Furthermore, the cabinet agreed on additional
sector-specific measures for buildings and heating, such as tax relief for energy-efficient refurbishment of buildings, apremium to promote the exchange of oil heaters for new, efficient heating systems, and the expansion of heat grids
and district heating with a view to integrating renewable energy sources into heat supplies, especially in densely
populated areas.

Global Roadmap recommendations
A global transformation to a highly energy-efficient and low-carbon buildings and construction
sector is essential to realise global ambitions to limit the rise in average global temperature to lessthan 2°C above preindustrial levels by 2030. The critical window of opportunity to address buildings
Page | 26 and construction emissions is in the coming decade, to avoid locking in inefficient buildings for
decades to come. There is an equally critical need to address energy performance improvements
and emissions reductions in the world’s existing building stock.
The following section outlines the key priority areas identified in GlobalABC’s 2016 Global
Roadmap (UNEP and GlobalABC, 2016) as well as the actions necessary to deliver a zero-carbon
global building stock.
Future GlobalABC work includes developing regional roadmaps to provide targets that are morecountry- and region-specific. For further information on best practices and examples of existing
policies and technologies for the buildings sector, see www.iea.org/buildings.

Updates on Global Roadmap activities
GlobalABC roadmaps focus on developing a collaborative approach across eight thematic areas
necessary to create a sustainable built environment for the future. Efforts exemplifying roadmap
ideas are being made in countries and cities all around the world, and this section highlights
numerous country-level case studies across various themes as examples of these activities (Box 5).

Urban planning
Urban planning policies should be used to reduce energy demand, increase renewable energy
capacity and improve infrastructure resilience. Globally, local jurisdictions have significant control
over how energy is used, and the emissions created by transportation, building construction andlifetime building operations can be regulated through urban planning. Urban planning can also help
combat climate risks by ensuring building resilience. Key actions in the area of urban planninginclude:••Enacting urban planning policies that account for the long-term goal of decarbonising thebuildings and construction sector.
District energy planning, i.e. enabling a systemic approach that can integrate energy demandand supply at the district level to deliver more efficient low-carbon solutions.

New buildings
There needs to be a higher uptake of net-zero-operating-emissions buildings. With the global
population increasing by 2.5 billion by 2050, new buildings will have an important effect on futurebuildings-related energy use and emissions. Several key policy, investment and design actions canachieve sustainable (low-emissions, efficient and resilient) new buildings:•••

Develop and implement mandatory codes. Transition from voluntary to mandatory codesthat set a minimum efficiency for new buildings.
Strengthen building codes. Establish a building code improvement cycle to strengthen
performance requirements every three to five years, with the aim of achieving zero
emissions and net-zero-energy codes.
Integrate renewable energy into new building designs to achieve net-zero emissions or netzero energy.

2019 Global Status Report for Buildings and Construction
Towards a zero-emissions, efficient and resilient buildings and construction sector••

Mobilise sustainable building financing. Facilitate widespread designing and construction ofsustainable buildings by raising access to/use of financing to enable private investment.
Lead by example. Develop policies ensuring that all new government facilities are efficient
low-emissions buildings.

Existing buildings
The rate of energy renovations and the level of energy efficiency in existing buildings need to be
increased. Key steps to raise the performance of existing buildings involve increasing both thenumber of buildings improved and the amount of improvement achieved.
•

•

•

•

Increase renovation rates in industrialised countries to an average of 2% of existing stock
per year by 2025, and to 3% by 2040. Renovation rates in developing countries should reach
1.5% by 2025 and 2% by 2040.
Increase the depth of renovation. Enable deep energy renovations that reduce energy
consumption of existing building by 30-50% or more.
Make renovation financing available. Raise renovation rates by increasing access to/use offinancing to enable private investment in renovations.
Lead by example. Develop policies ensuring that existing government facilities are renovatedto become efficient low-emissions buildings.

Building operations
Better energy management tools and operational capacity-building can reduce the amount ofoperating energy needed and, hence, emissions. While delivering efficient and resilient lowemissions new or renovated buildings is essential, it is equally important to manage existingbuildings efficiently. Key actions to improve the energy management of buildings include:

Installing energy management systems. Offer training in energy management systems anduse energy management processes in all buildings, particularly non-residential ones.
Strengthening human resources. Hire sustainability and energy managers and support
capacity-building among them.
Using smart controls. Deploy temperature, lighting and ventilation system controls andsensors as well as energy metering.
Making information accessible. Provide data and information that will help building
operators and occupants make better decisions.

Systems
It is important to reduce energy demand from systems, appliances, lighting and cooking. Energyconsuming lighting, appliances and equipment systems, which commonly have a shorter lifetime
than the buildings they are in, offer a significant opportunity to reduce emissions in new andexisting buildings. Key actions to increase system sustainability in buildings include:•••

Establishing minimum energy performance standards (MEPS). Develop, enforce andimprove standards to set product quality and performance requirements.
Mobilising financing for clean systems. Facilitate the use of sustainable products byincreasing access to/use of financing to enable private investment.
Leading by example. Develop policies ensuring that all government buildings invest in lowemissions and efficient systems.

Examples of other sustainability commitments and actions

Urban planning: Eskişehir's building efficiency policies and projects, Turkey
The Eskisehir Urban Development Project is one among a pioneering class of ecological restorations in urban areas
and a model for Turkish and global cities alike. With the technical support of WRI Turkey Sustainable Cities, theEskişehir Metropolitan Municipality has been developing and implementing a suite of building efficiency policies
and projects. A few priority projects include: Greener Municipal Buildings, Energy Audits, Job Training, and Public
Awareness-Raising. As part of delivering sustained progress on these priorities, the city is now designing amanagement scheme, possibly including a dedicated Municipal Energy Management Division, to weave building
efficiency into the city’s energy master plans.

Urban planning: La Marine Eco-district, Paris, France
The goal of La Marine Eco-district was to reclaim an industrial wasteland for the construction of a new sustainableneighbourhood of 6.7 hectares. The project was conceived by the Charles de Gaulle district to open up the site andcreate an urban and social link between the present and the future. Several project innovations contribute to thequality of the project: a biomass heat network supplies all the buildings in the eco-district and the social housing
stock in the south; the parking lots are shared to reduce the construction of infrastructure and limit the traffic impact
on the neighbourhood; and an installation aims to achieve zero rainwater discharge both in public spaces and at thelevel of each plot. Phase 2 was launched in 2017, and while the second part of this new neighbourhood was to belargely office-based, the state of the office building market required that the plan be revised to include nearly 300
new housing units and 27 social housing units. The space intended for economic activity has been reduced to
2 500 m², on the edge of boulevard Charles de Gaulle.

Urban planning/building retrofits: Universidad del Media Ambiente (UMA), Mexico
UMA produces zero wastewater, grows its own food and is surrounded by a growing, edible forest. The university
has also implemented green features that conserve natural resources. To reduce its energy consumption, classrooms
are ventilated naturally, solar hot water collectors are used for 100% of hot water demand and solar panels produce
electricity. The building is projected to reduce water use by nearly 90%, with a rainwater harvesting system on theroof and a black water treatment and recycling system. Innovative building materials such as compressed stabilised
earth blocks for the walls, timber window frames, etc., were used to reduce embodied energy by nearly 70%.

Building retrofits: Agency of Urbanism and Development of Guyana (AUDEG), Guyana
Thermal performance was improved by replacing awnings made of Wapa shingle with an aluminium solar brisesoleil, replacing windows with solar control glass, adding a tin canopy on the gable floor to the west, and adding a
vertical wooden sunshade at the entrance. Insulation has also been laid under the wooden floors to ensure better
thermal and acoustic quality and more efficient A++ air conditioners have replaced older, less-efficient ones, and alocally produced wooden mesh has been installed to protect them. Reversible fans have also been installed in all
offices.

Circular economy: The ROCKWOOL Group’s RockCycle programme, Denmark
RockCycle is a circular business model devised by the ROCKWOOL Group. The RockCycle programme varies bycountry, depending on the local situation. For example, the take-back programme for flat roof insulation in Germany
is offered in combination with the delivery of new ROCKWOOL material, allowing the company to make use of empty
delivery-truck runs from the place of delivery (mainly renovation sites) back to its production facilities, where thediscarded material is recycled. The installers pay ROCKWOOL a fee for this take-back service rather than paying todispose of the materials in a landfill, so there is a financial as well as environmental incentive to reduce landfill
waste.

Circular economy/new buildings: NEST, Switzerland
NEST is a living lab near Zurich, run by the Swiss Federal Laboratories for Materials Science and Technology and the
Swiss Federal Institute of Aquatic Science and Technology. NEST consists of a central building core and three open
platforms where individual modules can be installed based on the plug-and-play principle. These modules aretemporary apartments or offices in which people live and work and new ideas are tested. The system can be used
to validate new energy concepts and examine the potential for increasing efficiency and reducing CO2 emissions.

New buildings: Gillies Hall at Monash University, Frankston, Australia
Gillies Hall, a new student residence, is Australia’s largest Passivhaus building. Cross-laminated timber reducescarbon emissions by half, and the project is also fossil fuel-free thanks to its rooftop solar panels and all-electric
thermal plant.

New buildings/materials/resilience/clean energy: Konseguela business area, Mali
The buildings in the Konseguela business area were built according to the principles of the Nubian Vault TechnicalConcept promoted by the Nubian Vault Association (AVN) in Sahelian Africa for the past 20 years. Raw earth andlocal stone were used to make all the structures. Some outdoor spaces between buildings were embellished withlight IPE+ steel box covers, creating shaded and ventilated useable spaces at a lower cost. The photovoltaic
installation produces electricity, and a generator running on jatropha oil from locally cultivated seeds ensures peak
and backup electricity in the event of breakdowns or insufficient sunshine, and provides energy for non-electricalconsumption. An electrical energy storage device is also in place to ensure service continuity.

Materials/circular economy: Low-Carbon Charter, Hong Kong
Hong Kong’s low-carbon charter is an important private sector initiative that unites the whole value chain incommitting to a low-carbon buildings and construction sector.

New buildings: Net-zero-energy-ready buildings, Canada
The Government of Canada is currently investing CAD 48.4 million to support the development and implementationof deep retrofits for existing buildings and new net-zero-energy-ready buildings through research, development anddemonstration (RD&D) initiatives to accelerate the development of technologies necessary for highly energyefficient building design and construction practices.

New buildings: TADI Office Complex Building B, Tianjin, China
The project, which aims to create a comfortable, healthy and environmentally friendly workplace, uses thirty passive
and active technical measures, including the integration of renewable energy through a ground source heat pumpcoupled with a solar cooling and heating system. It has won several awards, including LEED Gold-Grade Certification.

Resilience: Climate-resilient Honiara project, Solomon Islands
This is a four-year project supported by the UNFCCC Adaptation Fund and administered by UN-Habitat, with multidisciplinary scientific support from RMIT University, Australia, that is working to reduce the vulnerability of thoseliving in informal settlements, through a range of co-designed initiatives. The overarching goal of this project is toenhance the resilience of Honiara and its inhabitants to current and future climate impacts and natural disasters,with a particular focus on pro-poor adaptation actions that involve and benefit the most vulnerable communities.

New buildings/materials: Waste collection logistics base, France
The bioclimatic design of the buildings improves passive energy gains, and the buildings are oriented to allow solar
gains without causing overheating. The office area opens towards the south and the west while the workshop side
is turned northwards to take advantage of indirect lighting and avoid overheating. The cost of the efficient, lowcarbon construction was equivalent to that of a standard constructions. Locally available hemp from the Vendée
was used in the wood frame, the walls are insulated with wood fibre and hemp concrete or vegetable wool, andvegetable wool insulates the roofs.

Building retrofits: BUILD UPON 2, Europe
BUILD UPON is the world’s largest collaborative project on building renovation; it aims to create a renovation
revolution across Europe by helping countries deliver strategies to renovate their existing buildings. BUILD UPON 2
is the second phase, designed to strengthen the effectiveness and implementation of the national building
renovation strategies required by the EU Energy Performance of Buildings Directive (EPBD). BUILD UPON 2 is being
led by a consortium of eight national GBCs. The eight pilot cities will develop and test a multi-level renovation impact
framework containing a suite of milestones and measurable progress indicators covering emissions reductions,increased employment and improved health. By capturing data at the local level, the framework will link renovations

2019 Global Status Report for Buildings and Construction
Towards a zero-emissions, efficient and resilient buildings and construction sector

to policy and decision-making processes at the national level. The overall aim of the project is to have at least 10
cities publicly commit to establishing strategies to decarbonise their building stock by 2050.

Systems: Multifunctional facade element for multi-story housing construction, Germany
A building’s facade can take on numerous functions of the building envelope. The German Federal Government isfunding a research project as part of its Energy Research Programme that aims to intelligently link these functions
into one system. To this end, scientists are developing a facade element with integrated organic PV, textile solar
protection, a sustainable insulation material and the sensors necessary for an overall control system. The
components are controlled via an intelligent overall control concept to increase the energy efficiency of the building
and user comfort. A high degree of prefabrication and the modular design of the facade element should make it
economical to use in multi-story residential buildings.

Materials: GreenPro ecolabelling, India
The main objective of using Greenpro certification in India’s ready-mixed concrete (RMC) industry is to make it easierfor RMC producers to adopt green measures and to enhance the environmental performance of their products withthe ultimate objective of reducing the industry’s GHG emissions. The certification system evaluates the green
features of RMC based on eight parameters: product design; product performance; raw materials; manufacturing
process; waste management; lifecycle approach; product stewardship; and innovations.

Building retrofits/materials: Les Fuschias residence, Paris, FranceThis project involves the renovation of a 60-year-old building to enhance its performance and meet the objectivesof the Climate Plan of Paris. Replacement of the cladding and the installation of improved insulation wereaccompanied by replacement of the boiler room and the ventilation system to ensure reduced energy consumption
as well as greater thermal comfort for the inhabitants. 80% of the waste materials have been reused and various
materials recovered onsite (wooden battens, aluminium plates and cladding boards) are being used to manufacture
items in the association’s workshops.

Building retrofits/systems /clean energy: Greenpeace Spain headquarters, Spain
Passive measures – including the use of high-performance glass, solar gains management, insulation and naturallighting – have been implemented to minimise energy demand. The building is cooled using an evaporative systemthat has an 80% lower energy demand than a conventional system and also avoids the use of chlorofluorinatedgases. The ventilation system incorporates a heat recovery system to reduce energy losses, and low-impact
ecological materials have been used, taking into consideration the lifecycle impacts of the materials. Existing
polyvinyl chloride (PVC) floors were replaced with cork, wood chips and recycled textiles for insulation. Forest
Stewardship Council (FSC)-certified wood for furniture and plant-based paints were also used. Greenpeace promotes
the shift to renewable energy by using 100% renewable energy from a wind turbine installed in Catalonia, and thebuilding’s use does not result in CO2 emissions since it is 100% electrified, using 100% renewable energy.

Building retrofits/urban planning/clean energy: Canada
The Government of Canada is providing CAD 1 billion in investments to the Federation of Canadian Municipalities
to retrofit buildings in Canadian communities and improve their energy efficiency. The Federation of Canadian
Municipalities advocates on behalf of over 2 000 municipalities at the national level and has a longstanding
partnership with the Government of Canada.

Clean energy: Bahnstadt Heidelberg (passive house estate), Germany
The urban area Bahnstadt in Heidelberg is a new settlement on unused land that provides apartments and jobs formore than 10 000 people. This extensive clean-energy-based sustainable housing development is one of the largest
demonstration projects in Germany. It meets the Passive House standard, with an average heat demand of
54 kilowatt hours per square metre (kWh/m²) for all heat applications (space heating, hot water, distribution andstorage losses) and allows only the efficient use of renewable energy. The local heating network uses a wood-fired
power station to provide for the remaining electricity and heat needs. The installation of smart meters in all
households and a comprehensive energy monitoring system enable further optimisation.

Building performance: Real estate emissions improvements, Global
Large building portfolio owners and real estate companies are making progress on improving their buildings’
performance. The Urban Land Institute (ULI) has published its 10th annual report on building performance (theGreenprint Performance Report) and marked the efforts of major real estate companies to improve the energy
performance of their building stock and reduce CO2 emissions. The 2019 report shows that for the 8 916 properties(around 200 million m2 of space) being tracked in 32 countries, emissions have fallen 1.5%, and ULI members
continue to make progress towards their commitment to reduce energy use 50% by 2030. The OID Barometer inPage | 312019 Global Status Report for Buildings and Construction

GlobalABC work areas
GlobalABC aims to bring together all elements of the buildings and construction industry as well as
countries and stakeholders to raise awareness and facilitate the global transition to low-emissions,energy-efficient buildings. GlobalABC works on a voluntary collaboration basis in five working areas
Page | 33
in which members are invited to take part.

Work area 1: Awareness and education
The purpose of this area is to support capacity-building to promote the transition to a resilient,
efficient and zero-emissions built environment and to raise awareness of the sector’stransformation potential, convey a sense of urgency, develop common narratives, and formulate
key messages. It aims to disseminate new approaches and solutions, share best practices throughthe new GlobalABC website, establish an interactive knowledge database to enhance peer
learning, and provide training and education through webinars and online courses.

Work area 2: Public policies
This area attempts to unite the numerous independent and scattered building and construction
sector stakeholders – particularly public authorities – through effective regulations and norms aswell as financial and fiscal incentives. It also aims to support the development of national alliances,promote the integration of sustainable building objectives into NDCs, and enable city andsubnational engagement. A local government public policies group has been created to identify
opportunities, facilitate community-level climate and energy strategies and promote co‑ operation
among national and subnational governments. Another sub-group focuses on adaptation and isdeveloping a report to be released in 2020 on how the building industry is readjusting.

Work area 3: Market transformation
This area is designed to engage businesses and other stakeholders in decarbonising the entire
buildings sector value chain, fostering multiple partnerships and a common culture among private
and public sector participants to facilitate market transformation. This involves defining voluntaryarrangements to prepare regulations and enable innovation in the market. It also includes
developing guidance on science-based targets that can be used to help transform the buildings andconstruction sector by identifying a common metric and language for all companies to use throughthe Science-Based Targets for Buildings (SBT4buildings) project led by the World Business Council
for Sustainable Development (WBCSD).

Work area 4: Financing
This area is working to narrow the public and private financing gap for investing in efficient andresilient zero-emission buildings and construction, including property development. It is also
helping draw attention to the sector’s financing needs, mapping existing financing opportunities,
promoting innovative financing tools, enabling the flow of reliable information for investors, andinforming public bodies of the budgeting and funding policies needed to conceive and implement
energy efficiency measures in buildings. For example, the International Partnership for Energy
Efficiency Cooperation (IPEEC) and the Japanese government organised the G20 Global Summit on2019 Global Status Report for Buildings and Construction
Towards a zero-emissions, efficient and resilient buildings and construction sector

Financing Energy Efficiency, Innovation and Clean Technology, recognising in its final Tokyo
Declaration how important it is for the real estate and buildings sector to begin shifting financing
towards energy efficiency.

Page | 34

Work area 5: Measurement, data and information
The purpose of this work area is to elaborate a fair and harmonised measurement system to close
the information gap and thereby support buildings and construction sector policies andinvestments with measurable, reportable and verifiable data. Key barriers, however, relate to
information availability, collection, quality, reporting, storage and accessibility. To overcome theseobstacles, the work area team is co‑ ordinating an industry-wide global effort to develop a digitalbuilding data and information collection tool, known as a “building passport”, to promote greater
cross-sectoral data transparency and consistency and information exchange.
All work areas welcome new participants. Please contact global.abc@un.org for more information.

information, and to make the topic more visible in national policy debates. Alliances can beorganised by the public or private sector as either volunteer-based or formalised structures.
National alliances offer recommendations for policy makers and actively work to enhance
economic activity. Typical pursuits range from awareness-raising, training sessions and project
assistance to legislative lobbying.
Page | 36

National alliances have been successfully established in France, Germany, Mexico, Morocco andTunisia, in many cases inspired by GlobalABC. Forming bridges among various sectors andindustries, these alliances bring together leading representatives of public, private and civil society
institutions for the creation of a sustainable buildings sector:
Plan Bâtiment Durable (PBD) [Sustainable Building Plan], France•
Allianz für Gebäude-Energie-Effizienz (geaa) [German Alliance for Building Energy Efficiency],
Germany•
Alianza por la Eficiencia Energética (ALENER) [Mexican Alliance for Energy Efficiency], Mexico•
Alliance Marocaine du Bâtiment pour le Climat (AMBC) [Moroccan Alliance for Buildings andClimate], Morocco•
Alliance Tunisienne Pour les Bâtiments et la Construction (ATBC) [Tunisian Alliance for
Buildings and Construction], Tunisia
PEEB currently supports the national alliances in Mexico (ALENER) and Morocco (AMBC) withawareness-raising activities as well as capacity-building and training for their members. Most
recently, expert working groups discussed the topic of buildings according to the five GlobalABC
working areas during the relaunch of the Mexican national alliance in September.
