Energy systems of green buildings in Australia

In this chapter, the status-in-quo of green buildings in Australia was provided by introducing the practical application of different types of energy system, including Solar thermal cooling system Geothermal heat pumps PCM cold storage in cooling system System control strategy A combination of innovations The chapter aims to contribute information on how much energy saving can be achieved in the building sector and how long the pay-back period is, for which a case study is provided for each type of energy system. These analyses are available in the results of the practical operation of energy systems after the completion of building construction, through which the incipient system design has been proven key to the energy saving of successful cases. Although building materials and construction process is not considered in the analyses, these case studies also indicate a rather high importance of material and resource use during building construction.
