Join Professor Alistair Sproul, Head of the School of Photovoltaic and Renewable Energy Engineering at the University of NSW, to discuss passive design for buildings, energy efficiency, and renewable energy.  He has over 30 years’ experience working in the renewable energy and energy efficiency sector, including for a number of Photovoltaic companies such as BP Solar and Pacific Solar. in R&D before taking on an academic position in 2001, carrying out research and teaching at the University of New South Wales.

Passive design is about designing buildings that are well insulated, shaded in summer and make use of the sun’s energy for heating in winter.  In addition to good passive design the recent rapid lowering of costs for Photovoltaics (PV) – means that roof mounted solar systems can supply the majority of the energy required by a residential building.  The cost of a fully installed PV system in Australia, with no subsidies, is now able to provide energy to a home at a cost of about one-third of the cost of electricity purchased through the grid and about half the cost of natural gas.  In combination with energy efficient appliances, lighting and highly efficient reverse cycle air conditioning – it is technically and economically feasible for buildings to greatly lower their carbon footprint without compromising comfort.
