Environmentally Sustainable Development

• MYOB HEADQUARTERS
10 WESLEY COURT, BURWOOD EAST
(GOLD ENERGY SMART AWARD FOR 2001)
In our role as designers of building services Connor Pincus and Saunders were acutely aware of the issues of sustainability and energy conservation. CPS is an inaugural member of the Green Building Council of Australia. We work closely with architects, project managers and building owners to optimise the incorporation of sustainable design principles to the full extent within project budgetary constraints.

Through the use of key tools such as the Carrier ES-2 energy calculation programme we were able to positively interact with the architect during the concept design process to analyse and advise on the relative benefits of building orientation, facade and shading options and construction material selection. Some brief examples of this important facet of our work

MYOB's strong commitment to sustainable energy design resulted in the incorporation of many passive energy saving measures into the building design such as high performance glazing, external sun shading and insulated spandrel panels to reduce insulation loads.

In recognition of the energy efficient systems that were installed the Sustainable Energy Authority of Victoria awarded MYOB Headquarters the GOLD ENERGY SMART AWARD for 2001.

Active energy reducing features of the mechanical services design included the use of central variable air volume air conditioning systems with full economy cycle operation, variable speed drives, central gas fired heating water and air cooled chilled water systems, CO monitoring and control of carpark ventilation systems and high velocity kitchen exhaust canopies.

In similar vein, the electrical services included such features as a fully programmable automatic light switching and dimming system for the general office lighting and a solar generated 160kVA emergency power backup system. Extensive arrays of photovoltaic cells and battery banks were integrated with UPS facilities and the building electrical reticulation system to form a tailored standby power solution capable of supporting MYOB's computer network, call centre and associated air conditioning equipment in the event of mains power failure.

• ST. LEONARD'S COLLEGE - BRIGHTON JUNIOR SCHOOL
This project incorporated passive cooling/night purging system in the form of automatic control of motorised vents at the highest points of the building. In the event that the building inside temperature was warmer than outside and needed cooling the vents would automatically open allowing warm air to rise through the open vents to outside with cooler air drawn in at low points. This effectively cools the building overnight reducing the necessity for airconditioning.

• SNAKE GULLY PAVILLION
This project incorporated an array of solar collector panels providing the bulk of domestic hot water demand for showers. A natural gas fired domestic hot water unit tops up the hot water storage only if required. Rainwater is collected from the roof and stored in a large water tank and is used for flushing of toilets.
