TREVOR PEARCY HOUSE
Trevor Pearcey House, the new head office of Australian Ethical Investment, is a leading example of sustainability in the refurbishment of an existing building. The Green Building Council of Australia awarded Trevor Pearcey House a 6 star rating representing World leadership in sustainable office building design and construction. It was the first building in the ACT, and was only the third in Australia, to achieve a six star rating from the council.
The original two-storey, 1100 m2 (GFA) building was 20 years old and was one of several units managed under a body corporate arrangement. The refurbishment covered base building and fitout and has involved a complete overhaul with a focus on passive systems and reuse of materials. Significant improvements have been made to the building fabric such as external wall insulation, upgraded roof insulation, operable double opening double-glazed windows, upgraded external shading, exposed internal mass and addition of thermal chimneys. These features allow the building to utilise natural ventilation for space conditioning and significantly reduce the need for heating or cooling.
Energy savings compared to the original building are estimated at 75%. Substantial water savings (estimated at over 80%) have also been achieved through the upgrading of sanitary fixtures and capture of rainwater to supply toilets. A major feature of the project has been the amount of material reused. The existing internal fitout was carefully deconstructed and then adaptively reused in the refurbishment. Reused items included carpet tiles, doors, joinery, ceiling tiles, metal studs, plasterboard, glass blocks, structural steel, insulation, miscellaneous fittings (including cabling, power points, etc). One of the features is artwork created from old computer floor tiles. New items installed were predominantly recycled such as, entry mats made from old car tyres, recycled timber floor and wall boarding, recycled carpet tiles and pin boards from recycled newspaper.
The refurbishment was delivered on a conventional budget ($1700 per m2) and demonstrates that significant environment improvement can be achieved in our existing building stock and that simple, passive systems can deliver comfortable and productive work spaces.
