Circular Economy Performance Contracting: the contract that does not exist …yet
Authors: Bougrain Frédéric 
Published: November 2020

Abstract
In 2017, construction and demolition waste were again the heaviest waste stream in France with 227.5 million tonnes (42.2 million tonnes for the building sector). To achieve a 70% (by weight) recycling target by 2020 for non-hazardous CDW various policies have been launched by the French government. However, public procurement has been neglected. In the field of energy saving, energy performance contracting has been widely used to guaranty energy efficiency improvement after building refurbishments. The paper shows how this approach could be duplicated to building deconstruction projects. Circular Economy Performance Contracting (CEPC) would encourage creativity of the deconstruction contractors and the value-chain and maximise circularity. It would lead to significant environmental benefits (e.g. increase of reused products and materials, reduction of CO2 emissions).
Applied SBTOOL to the Research on Performance Evaluation of Green Buildings in Southern Taiwan - A Case Study of the Residential Building Designed for Pingtung County Self-Government Ordinance for Green Buildings
Authors: Chang Kuei-Feng , Chou Po-Cheng 
Published: November 2020

Abstract
The global climate change and the lack of environmental resources, the issue of sustainable development have been emphasized by global. In response to the development of a sustainable environment, in recent years, ‘green buildings’ have sprung up in large numbers, and the aspect of architectural technology are constantly making breakthroughs and innovations. Whether it is a library, a school building, or even a residential office building, it emphasizes to make a step towards ‘green’. The Pingtung County Government has established the Pingtung County Self-Government Ordinance for Green Buildings in 2016 to regulate the new constructions’ designs in a certain scale must according to thermal insulation, energy conservation, health, and sustainability. This study is to explore the applicability of SBTOOL to green buildings in southern Taiwan, accordingly choosing new-built residential cases in Pingtung County. Pingtung County is located in the south of the Tropic of Cancer. The local climate is hot and enough sunshine, there are many typhoons and rainstorms in summer. The residential planning is according to the ‘Self-Government Ordinance for Green Buildings’ of the Pingtung County Government. Both cases are designed by different construction companies and are the traditional southern Taiwan street house style. The planning concept also considers the current aging of the population in Taiwan and barrier-free environment design. After the evaluation, the scores obtained are between Acceptable Practice and Good Practice, only the barrier-free environment and universal design cannot clearly include in the assessment. On the whole, it is applicable to evaluate the ‘Green Building Residential Case in Pingtung’ by SBTOOL. This study hopes to make the residential cases whose designs are conforming to the Pingtung County Self-Government Ordinance for Green Buildings can provide a reference for the architectural design of the similar climatic environment and geographical features in the global, through the evaluations and analyses of SBTOOL.
Felleshus and Paradiset in Vallastaden – care for social sustainability in a new neighbourhood
Authors: Eidenskog Maria , Glad Wiktoria 
Published: November 2020

Abstract
In recent years, the development of new neighbourhoods in Sweden has included social sustainability as an overarching aim. This research project focuses on Vallastaden (development of which began in 2017 and is still ongoing), host of Sweden’s largest built environment exhibition. The research explores how social sustainability was interpreted during the different phases of the project and how the built environment was constructed in relation to defining social sustainability. The results show that the planning process included a wide variety of stakeholders, and that social sustainability was defined broadly, with some versions being foregrounded and others backgrounded. Notably, some elements for residents, such as the so-called “felleshus” – large greenhouses with communal social spaces – and Paradiset – land designed for permaculture and urban gardening – were brought to the fore. Felleshus and Paradiset have been studied in greater detail: How have these communal spaces been developed over the last two years? Specific attention was paid to socio-material relationships. The empirical material shows various tensions between residents, activities, practices and the built environment. To deepen our understanding of the results, theoretical approaches relating to “matters of care” and ethico-political dimensions of care have guided our analyses. With these approaches, the work performed to achieve what was expected from felleshus is acknowledged, as are the effects of the work and relationship-building involved in felleshus and Paradiset. The conclusion is that social sustainability involves many processes, which might take time and evolve in unexpected directions. Openness to these processes must be taken into account when planning and constructing similar neighbourhoods.
Development of the Local SDGs Platform for information sharing to contribute to achieving the SDGs
Authors: Kawakubo Shun , Murakami Shuzo 
Published: November 2020

Abstract
Think Globally, Act Locally: Working toward the Sustainable Development Goals (SDGs) at the local level while taking global trends into accounts is key to transforming our world. Many cities and communities are now incorporating the SDGs into their visions, strategies, policies and measures. The current situation surrounding the SDGs is shifting from the understanding phase to the practice and follow-up phase. Cities and communities working toward the SDGs are expected to conduct Voluntary Local Reviews and to share their experiences worldwide. The paper introduces an outline and the development methodology of an online “Local SDGs Platform” that enables stakeholders to register, search and share their efforts and best practices toward achieving the SDGs. Platform users can understand the actual situation of cities and communities using local SDG indicators, which were specifically developed to reflect the local context in Japan. Although the platform and local SDG indicators were initially developed for Japan, the framework and its development methodology are universally applicable and relevant in any region or country. Effective utilization of the platform together with local SDG indicators is expected to support connecting stakeholders, understanding their actual local situations and sharing information, which will lead to achievement of the SDGs.
Guidelines with routines and documentation for handling energy requirements within the building process
Authors: Wahlström Åsa , Hagnell Andreas , Govén Birgitta , Edenhofer Victoria 
Published: November 2020

Abstract
As a result of the energy performance of the buildings directive (EPBD 2010), the requirements have been gradually tightened in the Swedish building regulations. For the purpose of the directive to be realized, it is becoming increasingly important to ensure that buildings actually live up to the minimum rules laid down in the Swedish Building Regulations (BBR) or more ambitious requirements imposed directly by the clients. To gain more insight into these questions, today´s building process has been studied through interviews and workshops with regional actors in seven regions around Sweden. A guideline is proposed with new routines and documentation for the building process, i.e. handling of starting clearance, designing of inspection plan and follow-up for final clearance.
Concept for next generation of technical energy regulations in buildings
Authors: Sulzer Matthias , Orehounig Kristina , Knoeri Christof , Niffeler Mathias 
Published: November 2020

Abstract
The research project EnTeR analysed the role of technical energy regulations (TERs) in the transformation of the building stock and their integration into the future energy system. The main task was to identify effective measures which can guide stakeholders to achieve CO2-emission targets by means of TER. Based on this, recommendations for future energy legislation are derived. The international analysis revealed that TERs, despite their previous success in increasing the energy efficiency of the building stock, seem to be reaching their limits. Particularly when it concerns the decarbonisation of the building sector. The literature lists therefore the following five challenges: (i) Further increase in energy efficiency, (ii) consider “grey energy”, (iii) increase the share of renewable energies, (iv) close the “performance gap”, and (v) accelerate the renovation rate. Through technical and economic optimizations (Energy Hub optimization, Pareto Front), it was possible to identify solutions for the Swiss building stock which achieve specific CO2-emissions below 10 kgCO2/m2 - typically at CO2 avoidance costs of 200-400 CHF/tCO2 compared to cost-optimal solutions. In order to provide the best possible regulatory environment for the building stock to develop in the intended direction, a TER concept was developed based the three main life-cycle phases of a property (construction, operation and decommissioning): 1. The TER «Capacity Limit» is proposed for the construction phase (planning and building). The limitation of capacities (electricity, heating and cooling) forces energy-efficient buildings by reducing grid loads and providing incentives for installations of renewable production and/or storage systems. 2. For operation phase (usage), the TER «Energy Mix» is proposed. The proposed TER limits the amount of allowed CO2-emissions during the operating phase. Enforced by Smart Meters and Digital Data Platforms. 3. For the decommissioning phase (material) the TER «Material Cycle» is proposed. The proposed TER aims to reduce this ‘grey’ share by imposing a deposit/pledge system on building materials
Assessing the energy efficiency of a district’s existing building stock glazing – Case Study TU Dresden
Authors: Roosmalen Maartje Van , Weller Bernhard 
Published: November 2020

Abstract
Restoration of existing buildings becomes inevitable due to urbanization, population growth, conservation laws and scarcity of resources. Upgrading existing glazing could reduce building heating demand by 10% and reduce the TUD emissions by 573.4 tco2-eq/a. However, renovations are often postponed due to unknown energetic glazing quality. Traditional measures such as removing the glazing to a test-lab to identify the ug-value are often not permitted nor practical for existing (heritage-listed) occupied buildings. In this article, methods suitable for the assessment of the energetic quality of existing glazing without removing the glazing from the building, i.e. (a) the use of literature values per building age classification, (b) glazing built up measurement with ug-value calculations per standard and (c) direct ug-value measurement using a portable tool, are tested on the existing window stock of the TUD campus, compared and evaluated in terms of accuracy and easiness of application. Results show that the energetic quality can range widely from a ug-value of 0.5 to 3.5W/m2K within a single building, and that method (a) is not accurate and method (b) is as accurate as method (c), but 20 minutes faster per glazing which, extrapolated to a district like TUD, can save months of work and significantly increases the chances of glazing renovations being carried out.
Transnational common sustainability indicators for harmonising built environment assessment systems in relation to SDGs
Authors: Moro Andrea 
Published: November 2020

Abstract
Common Sustainability Development Goals (SDGs) have been set by the 2030 Agenda of United Nations in 2015. The European Commission committed to implement the SDGs and now Member States are preparing National Sustainable Development Strategies for contributing in the SDGs achievement. At a lower government level, regions and cities are also implementing their local strategies. Concerning the SDGs dealing with the built environment, how would it be possible to connect the global and local level strategies? To measure the progress towards SDGs and relative targets, a global framework of indicators has been set by UN. Many UN indicators have been adopted by the European Commission. The value of global indicators depends on the results achieved at local level, consequently quality and reliable local disaggregated data are necessary for the measurement of the progress towards the common goals. In the building sector, rating and assessment systems at building, urban and territorial scale can play a key role in this sense. The implementation and adoption of a core set of key performance indicators (KPIs), based on common metrics, in the existing and future assessment systems would allow to aggregate the information from the single building to the global level connecting the indicators trough the spatial scales. Common KPIs would also allow to compare the performance reached by buildings certified with different systems in relation to SDGs. The paper will illustrate the core sets of indicators elaborated and tested in 10 European countries by CESBA (Common European Sustainable Built Environment Assessment) in collaboration with iiSBE (international initiative for a Sustainable Built Environment) through two European Interreg projects at building, urban and territorial scale, in the form of a built environment Passport for the harmonization of assessment systems in relation to SDGs.
Knowledge management of sustainable construction processes
Authors: Jonasson Jonas , Mikaelsson Lars-Åke , Persson Urban 
Published: November 2020

Abstract
As the building construction industry accounts for a large part of the ecological burden, sustainable construction processes are very important for achieving sustainable communities. Construction is often a linear process, where different actors act at different stages of the process. In this process there are critical borderlines where the information is to be transferred from one actor to another. Over the years, the construction industry has developed a well-functioning and standardized arrangement for how this happens. However, this has proven to be problematic when sustainability is to be introduced in construction projects. Sustainability goals can often be perceived as diffuse and difficult to interpret. Different actors with different values and knowledge level regarding sustainability also interpret the goals differently. A common way is to set environmental goals as checklists with criteria to be met. In this process, it is common for certain aspects to be sub-optimized while other important aspects fall outside the scope. It is therefore very important to simplify the sustainability parameters without sacrificing complexity. The goals must be clearly formulated initially and followed up continuously throughout the process. The purpose of this paper is to study and analyze good examples of sustainable construction processes with regard to clear goal formulation and continuous follow-up. The result end up in a proposal for a model for knowledge management of sustainable construction processes.
SUSTAINABLE BUILDING ENGINEERING BY BLENDED LEARNING
Authors: Mikaelsson Lars-Åke , Hermansson Fredrik , Jonasson Jonas , Danielski Itai , Lindström Susanne 
Published: November 2020

Abstract
The sustainable building engineering education at Mid Sweden University has since it started 1994 a strong focus on sustainable building. It is also committed to be a pilot case for blended learning. All courses in the building engineering program were from the autumn 2012 adapted to a blended learning concept. That means that all courses are available in an integrated mix of ordinary campus and online distance education in real time.
Blended learning is a way of taking in account different needs concerning student study situation. Adult students, bound with house and families, often prefer more distance education while younger students need more campus education.
The results of the case study show that blended learning attracts more students, and allows students with different backgrounds to study and gives a more solid base of students for the program. It also allows a more flexible way of allocating resources by integrating two previous modes of delivery for the same program. This provides an education with a well thought through quality assurance. Another strength of blended learning is the possibility to connect individual students to a larger collective of students, making it possible for them to relate to and learn with and from others by social interactions that are difficult to achieve in solely online education.
The pilot case is so far limited to the sustainable building engineering program but in a next stage the concept is planned to be spread to other engineering programs and other education programs at Mid Sweden University.
Concepts and type building for carbon neutral construction in arctic Finland based on tradition
Authors: Vares S , Savolainen P , Häkkinen T , Shemeikka J , Huttunen M , Zubillaga L. 
Published: November 2020

Abstract
This paper discusses traditional solutions for carbon neutral construction in arctic conditions. We consider that vernacular architecture forms an important source of knowledge to resource-wise, energy-efficient and sustainable ways to organize human dwellings and settlements. The key tasks of our research were to (1) identify the factors of traditional arctic construction that have an impact to sustainability and carbon-neutrality of arctic building and to (2) develop and assess a type building for arctic districts (Finland), based on traditional solutions, that fulfills the functional prerequisites for modern living comfort and energy requirements. The study is based on literature, fieldwork and Life Cycle Assessment calculations for the theoretical case. The life cycle assessment includes greenhouse gas emissions and carbon storage in timber and bio-based materials. Energy usage follows the principles of carbon neutrality. Wooden products used in the construction store biogenic carbon from the product stage to the building demolition stage. The case study calculations showed that operational energy demand could be fulfilled with the use of solar PV, solar collectors, ground source energy and district-scale wind energy supply. Results show that the biogenic carbon content is more than enough to offset the emissions from building materials and renewable energy technologies needed for operating the building. The research was funded by the Finnish Ministry for Foreign Affairs.
Barriers, drivers and prospects of the energy efficiency code in the Lagos real estate market

Published: November 2020

Abstract
This paper explores potential bariers and drivers to the uptake of new regulations for energy efficiency currently being introduced into the Lagos real estate market and how professionals percieve this, and then discusses how these might impact on achieveing SDG 7.2. An online survey of thirty real estate professionals involved in property development sector was carried out to ascertain this. The sampled real estate professionals are those listed in directories of Real Estate Developers Association of Nigeria, as well as professionals who had taken part in a federal government sponsored energy efficiency training in Lagos. Analysis of the close-ended questionaire was carried out using simple descriptive statistics, while open ended questions were analysed using ATLAS.ti 8, a computer aided qualitative data analysis software.
There is a very positive outlook for the adoption of the energy efficiency code in Lagos, although professionals believed most of the prescriptions of the code are achievable only in the long term (that is not before the next five years). In reality, this signifies a risk to the process as policy push-backs from change in government has been experienced in recent times. Actions towards promoting policy entrenchment of the code in planning agencies, voluntary adoption of the code by professionals and their clients and engagement of a wider range of built environment professionals are recommended to ensure that Lagos attains a sigificant level of energy efficiency in its real estate development sector in the short to medium term.

Published: November 2020

Abstract
Solar power is very useful renewable energy, got anywhere. But it is got only in the daytime on sunny days. On the other hand, sometime the grid cannot receive overflowed solar power when electric demand is small. Recently storage battery is utilized in the grid, in the household, combined with solar power generator for accumulating overpowered electricity and emitting it after sunset. It is very useful to utilize solar power effectively and efficiently. It is also useful on the power failure. But we have very little information of technical traits of storage battery, such as energy loss with accumulating and emitting electricity. Building Research Institute in Japan has a demonstration house, which has solar power generator and storage battery combined system. The authors have measured generated solar power, accumulated and emitted overpowered electricity of solar power generation and storage battery combined system for a year. Lots of traits of solar power and storage battery combined system are got. The authors have made modeling and formulation solar power and storage battery combined system, incorporating these traits. In this way, efficiency and effectiveness of solar power generator and storage battery combined system with any generation, storage capacity, can be evaluated with this formulation.
Solar power based heating systems with electrical storage as alternative to fossil based systems for small residential buildings

Abstract
Renewable energy is expected to replace thermal power by fossil fuel for reduction of green gas emission, air pollution and energy-security. Especially solar power generation is expected because it is got anywhere and its cost has reduced recently. But it is got only in the daytime on sunny days. Furthermore the amount, the time period it can get depends on seasons, weathers. Storage battery is essential for accumulating overpowered electricity and emitting it after sunset. The peak electricity demand is important factor to design electricity power plants. There are large electricity demands in summer and winter by air-conditioning. It is important to replace them by solar power with storage battery Building Research Institute in Japan has a demonstration house, which has solar power generator and storage battery combined system. The authors have measured how this system worked with air-conditioning electricity demand in summer and winter. And the authors applied these results to the actual electricity demand in Tokyo Metropolitan area. If solar power generator is combined with storage battery, it could cover air-conditioning cooling demand completely. In winter, peak electricity is high in morning and evening. So solar power could not mitigate electricity supplying demand in winter directly. But it is expected to supply electricity for a whole day, combined with storage battery.
