摘要：Energy consumption in the buildings is responsible for 26% of Australiaâ€™s greenhouse gas emissions where cooling typically accounts for over 50% of the total building energy use. The aim of this study was to investigate the potential for reducing the cooling systemsâ€™ environmental footprint with applications of alternative renewable energy source. Three types of cooling systems, water cooled, air cooled and a hybrid solar-based air-conditioning system, with a total of six scenarios were designed in this work. The scenarios accounted for the types of power supply to the air-conditioning systems with electricity from the grid and with a solar power from highly integrated building photovoltaics (BIPV). Within and between these scenarios, systemsâ€™ energy performances were compared based on energy modelling while the harvesting potential of the renewable energy source was further predicted based on buildingâ€™s detailed geometrical model. The results showed that renewable energy obtained via BIPV scenario could cover buildingâ€™s annual electricity consumption for cooling and reduce 140 tonnes of greenhouse gas emissions each year. The hybrid solar air-conditioning system has higher energy efficiency than the air cooled chiller system but lower than the water cooled system.
