SINGAPORE, 6 September 2018 – A Wellington building has taken out an international green award at a gala ceremony in Singapore.
Aorangi House on Molesworth Street, home to engineering consultancy Beca, was praised by the World Green Building Council as a ‘well-deserved winner’, and a ‘stellar example’ of a green building.
Aorangi House is one of New Zealand’s most
energy-smart buildings, and co-won the Leadership in Sustainable Design & Performance
Award in the Commercial category, alongside Barangaroo South in Sydney, Australia, as part of the World Green Building
Council’s (WorldGBC) Asia Pacific Leadership in Green Building Awards.
The biennial awards programme celebrates iconic green buildings,
up-and-coming innovators and inspiring companies driving change and creating a
better future throughout the Asia Pacific region.
outdated 1970s office block in Wellington, the Aorangi House revitalization
project demonstrates how the up-cycling of an existing commercial office
building can not only significantly reduce environmental impact but also
achieve positive user perceptions coupled with leading environmental
The building was
vacated in 2005 due to issues with heating, cooling and ventilation. The single
glazed windows leaked, and the uninsulated façade was considered
user-unfriendly. The building remained untenanted until purchased by developer
Prime Property Group.
The design team
consisting of Beca building services engineers and Studio Pacific Architects
adopted an integrated design approach to the major refurbishment. The strategic
design had to meet tenant and landlord economic requirements and focussed on
achieving value added outcomes with the end user in mind.
In the reuse of
the existing building structure, the project saved significant embodied energy
and embodied emissions compared to a new construction project. For
continuous improvement, the building tuning and replacement of the gas boiler
with VRF heating resulted in the building’s operations becoming significantly
more efficient well after the original refurbishment.
refurbishment, there were a number of significant improvements, including the
infusion of passive solar design principles (natural ventilation, exposed
thermal mass and external insulation, natural lighting) that significantly reduced
the energy demand. These and other measures resulted in 64% energy savings, 78%
operational waste diversion and a re-used building that saved both demolition
waste and energy for new materials.
A Post Occupancy
Evaluation carried out by Victoria University of Wellington placed Aorangi
House as top building overall in the New Zealand dataset. Contributing to this
were excellent relative perceptions of the overall comfort of the building and
its perceived influence on the health and productivity of the users.
The success of the
Aorangi House revitalization project demonstrates how existing buildings can be
effectively rejuvenated utilising a performance focussed approach to lead the
transition towards a sustainable built environment.
The jurors of the Leadership in Sustainable Design &
Performance Award in the Commercial categorywere Prof Lam Khee Poh, Provost’s Chair Professor,
Dean (School of Design & Environment), National University of Singapore;
Brian Dean, Energy Efficiency, International Energy Agency, and Autif Sayyed,
Green Building Specialist, International Finance Corporation, World Bank.
Juror Prof Lam Khee Poh,
Provost’s Chair Professor, Dean (School of Design & Environment), National
University of Singapore said: “To effectively move the needle towards achieving a sustainable built
environment globally, it is imperative that we deal with the huge existing
stock of buildings that are not performing to the standards that we now expect
in order to meet the sustainability goals. In some respects, it is a more
challenging task than building new, having to deal with the given physical
The Aorangi House
Revitalization Project successfully demonstrated that when there’s a will,
there’s a way. It adopted a comprehensive passive design strategy to maximize
the performance contribution while augmenting with active systems to deliver an
integrated mixed-mode solution that has proven to work well.”
Joelle Chen, Regional Head of WorldGBC’s Asia Pacific Network said: “Our Green Building Councils in the Asia Pacific
Regional Network work with some of the most pioneering companies and innovators
on green building.
The Aorangi House refurbishment project is a
stellar example of how an existing building can be made energy-smart with
integrative design and occupant engagement. Punching above its weight, it
raises the bar for existing buildingrenovation projects to follow and a well-deserved
winner of the Leadership in Sustainable Design & Performance Award in the commercial category.”
Ben Masters, Associate – Building Services at Beca New Zealand said: “Consideration must be
given to recycling existing building stock to target the aspirational Zero
Carbon buildings goal and we hope this award demonstrates that sustainable
refurbishment is a viable option to the carbon-hungry alternative of demolition
and replacement. We are proud to call Aorangi House our Wellington home and to have
contributed to the positive building performance outcomes”
Aorangi House was crowned a co-champion
