Modelling net zero energy options for a sustainable buildings research centre

The Sustainable Buildings Research Centre (SBRC) currently under development at the University of Wollongong will be an exemplar in respect of demonstration of a range of technical and operational means of reducing greenhouse emissions and other ecological impacts. This paper details the constraints and opportunities presented to the project in terms of renewable energy production and minimization of building energy consumption. The building performance was simulated using variety of tools for a range of ventilation and air conditioning options. Energy generation and demand management options considered include: earth-to-air heat exchangers; ground source cooling and heating; building integrated solar air heaters; natural and mixed mode ventilation schemes, etc.
