Summary

Australia is currently facing the challenge of dramatic peak electricity demand due to large residential and commercial heating, ventilating and air conditioning penetrations. Research indicates that the Australian building industry accounts for 40% of the nation’s total electricity energy consumption and is responsible for 27% of national GHG (greenhouse gas) emissions. Commercial buildings in particular, consume approximately 61% total building energy consumption and 10% total building GHG emissions. In addition, the heating, ventilating, and air conditioning (HVAC) system is a major contributor to the building energy consumption. Therefore, developing innovative HVAC technology towards sustainability is vitally crucial for Australia to decrease the nation’s electricity energy consumption and GHG emissions.
Since Australia has abundant solar energy resources with the highest average solar radiation per square metre in the world, solar air conditioning technology is highly desirable, as its availability coincides with the cooling demand. Thus, the peak electricity demand due to wide use of air conditioning in summer can be reduced, as it matches with the peak solar irradiance. This provides significant opportunities for Australia to develop solar cooling applications in buildings. However, although several solar cooling research and studies have been carried out in Australia recently, little research on the feasibility of different solar assisted cooling systems using different solar collector types have been conducted from the techno-economic point of view. And there are no comparative investigations about different solar cooling applications for all Australian climates.
