New Zealand Institute of Quantity Surveyors Report to PAQS
Sustainability Committee
By Barry Calvert, MNZIQS, Reg.QS
November 2018
New Zealand signed the Paris Agreement on 22 April 2016 and formally ratified
this important decision six months later. We are now committed to taking action on
climate change and to meeting our targets for emissions reduction.
After the general elections in September 2017, New Zealand welcomed its firstever authentic coalition government led by the NZ Labour party. The coalition
includes the NZ Green party who share a number of key environmental and social
policy viewpoints with Labour. No doubt this partnership has encouraged the moveaway from our reliance on fossil fuels towards more public transport and electricvehicles.
The New Zealand Green Building Council (NZGBC) have been very proactive with
their submissions to central government, gaining the attention of five cabinet
ministers including ministers for construction, housing and climate change. As aresult we have seen a number of key improvements in the way we build in NZ.
NZGBC successes over the last 12 months are:a) Over 80% of all new commercial buildings currently under construction in
the Auckland CPD will be 4 or 5 Greenstar (4 = Best Practice, 5 = NZ
Excellence).
b) There is a commitment from the new government to build a good
percentage of new social housing that complies with 6 Homestar.
c) One of NZ’s largest commercial real estate agents Bayleys released areport late 2017 documenting the benefits for landlords and commercial
developers of building green – report attached. This has received someattention from both private sector tenants and government agencies looking
to lease office space.
d) The Green Building Council of Australia today confirmed that Panuku(Auckland city’s urban re-development agency) has been pre-awardedcredits under Green Star – Communities for their efforts to provide liveable,
healthy, resilient communities.
The New Zealand Institute of Quantity Surveyors (NZIQS) is encouraged by the
momentum created from NZGBC’s efforts and is partnering with them on a numberof initiatives.
We are also building a relationship with members of the international Passive
House (PH) movement, thanks to Rob Bernhardt, the CEO of Passive House
Canada who we met at PAQS 2017. Rob agreed to speak at our national
conference in June of this year and has introduced us to his PH colleagues in NZ. I
will be attending their conference in Wellington next March.
NZIQS have been actively seeking green build cost data from our members
nationally. We recently became aware of a study from one of NZ’s larger QS
consulting firms which outlines the cost premium of building residential housingthat complies with NZGBC’s Homestar rating tool. I have attached a copy of thisstudy, which is now publicly available. It makes interesting reading and shows thatbuilding a 6 Homestar dwelling can be achieved with very little additional cost(over building to NZ building code minimums), which is very encouraging,
especially in the light of similar data coming out of the United States and Canada.
In summary, this has been a good year for New Zealand in the area of sustainablebuilding practices. We look forward to the next 12 months with anticipation of evenmore progress.

Yours sincerely,

Barry Calvert
NZIQS President

CLEAN GREEN NZ JOINS THE MOVEMENTENVIRONMENTAL
IMPACT EXTREME
Despite representing just 3% of theworld’s landmass, the built environment:• uses 40% of the world’s energy• emits 30% of the world’s carbon footprint•	uses 14% of the world’s drinking water
Overlay this with the fact that the world’s
urban population is:•	increasing by around 70 million peryear, and•	by 2050 almost 70% of the world’s 9.7
billion population will live in cities
This means more buildings will beneeded along with increased sustainablebuilding management.
In short, the future of buildings and thefuture of sustainability are becoming
inextricably linked.

The recent green construction
movement had its origins in the
1990s, initially as a fringe activity but
increasingly, over the past two decades,it has gained main-stream status.
The UK and US were the first to lead thecharge with momentum growing more
rapidly amongst other OECD countries
in the 2000s and beyond.
In NZ the movement really kicked up agear in 2005 with the formation of the
NZ Green Building Council (NZGBC) andin 2006 NZGBC became the 6th memberof the World Green Building Council(currently 100 members). NZGBC beganoffering 4 to 6 Green Star ratings in2007 for “design”, 2008 for “built” and2009 for “interior” projects. From 2018
the NZGBC plans to streamline theprocess further and phase out “design”
certifications, focusing instead on “built”
and “interior’ certifications.
Seen as a third party quality-assurance
to owners and added value to buildings,
the adoption of green building standards
in NZ has been market led rather thanregulation driven as in some European
countries and other parts of the world.

Summary: Respondents felt the most important shift in NZ’s built environment over the next decade will be an increased focus
on building performance and whole of life costs. The key barrier to improving building quality was seen as a focus on costs
rather than benefits.

A growing number of global cities
are embracing the move to green
rated buildings.
This growth has been particularly
strong over the past 10 years with
momentum continuing to build as
more cities commit to thecertification process.
Auckland is definitely tracking in
the right direction but still hassome way to go when comparedto other leading Pacific Rim cities.
This is probably a reflection ofdifferences in the timing and scaleof development cycles and the sizeof each cities population and total

BAYLEYS OCCUPIER SURVEY
Summary: A majority of respondents felt a buildings Green Star rating would be moderately to very important at their next move.
By comparison most overwhelmingly felt retro-fitting older buildings to improve energy efficiency was a good idea (even thoughmost did not link these improvements to potential opex savings). Opinions varied regarding the benefits of occupying a green
building, the most supported views included the ability to attract and retain better calibre staff, a reduction in staff downtime andalso better engagement between staff members.

BEING GREEN IMPROVES PERFORMANCE

In 2013 the NZ Green Building Council
began administering NABERSNZ, an
adaptation of Australia’s “National
Australian Built Environment Rating
System” (NABERS) model. Unlike
Green Star which is used during thedesign and construction of new builds/
major refurbishments and covers acomprehensive 9 category rating system,
NABERSNZ looks solely at the energy
performance of buildings. It is used oncebuildings are occupied and operating fora year or more provides a clear view of
how well a building or tenanted space isusing energy.
In NZ, commercial buildings use justThe ease and simplicity of NABERSNZ has
seen its popularity grow in NZ especiallyamongst owners of existing properties whoare seeking to retro-fit and show tangible
improvements in energy performanceboth for occupiers and owners.
Argosy’s use of the NABERSNZ system attheir recent Te Puni Kokiri office upgrade
at 143 Lambton Quay in Wellington saved
the occupier around $80,000 per year inenergy costs and also reduced their carbon
footprint. In Auckland, Precinct Properties
instigation of NABERSNZ at Zurich House
led to a significant 45% improvement inenergy performance over the last 3 years.

The drive towards net zero energy
buildings (i.e. buildings which produce
enough renewable energy to completely
off-set the energy they use) took a major
step forward following the Paris Climate
Change Conference in 2015 whereworld leaders agreed to limit global
warming to 2 degrees by the second halfof the century. In order to meet that
timeframe the building sector globallyneeds to achieve almost zero fossil fuelCO2 emissions by about 2050 which
implies a rapid shift in building design,

in NZ under NABERSNZ could well be
the catalyst to drive further sustainablegains. NZBC is due to launch a new
Green Star tool called Green Star

includes all the same categories as a newbuild Green Star rating but focusing on
operational performance rather than as
built performance.

Cost of Homestar Report

GENERAL
1.1 Introduction
As requested we have completed an estimate of the additional costs to achieve a 6,
7 and 8 star house in Auckland, Wellington and Christchurch.
The study adopted use of a 'baseline' dwelling design against which to assess
quantity-based costs. This design was identified as representing a typical market
product with the following attributes:- A two-storey 180m2, three bedroom, two bathroom house with double garage on arelatively flat site.
- Timber frame construction with 90mm external walls.
- EPS waffle-pod ground floor slab. Please note that an EPS waffle-pod slab is notalways required for Building Code Compliance. The cost to upgrade from astandard reinforced concrete ground floor slab to an EPS waffle-pod is $3,700 for
this house.
- A mix of brick and weatherboard external walls, solid aluminium frame doubleglazed windows with no gas fill or special coatings, and long-run corrugated roofing.
- Electrical, mechanical and plumbing required to meet the Building Code including
entry level instantaneous gas water heater.
- Mid-market specification for bathrooms, kitchens and other fittings.
1.2 Changes in this Revision
The 8 star option has been included for each city.
We were additionally asked to provide an estimated cost for underfloor heating using
heatpump as hot water source.
1.2 Key Results
The estimated additional cost over standard construction to achieve each star rating
is:
