Summary

Increasing energy use in commercial buildings from warmer weather due to climate change has been identified as a cause for concern over recent years. Although considerable research has been undertaken into the resulting increase in energy consumptions in both residential and commercial buildings, along with a decrease in comfort levels in unconditioned buildings, little has been done to address the impact to specific operational strategies and the influence this could have on future building design and optimisation. Simulations were undertaken for 2030 and 2050 for major capital cities in Australia to demonstrate the effect on the day and night-time potential for free cooling. Results showed that while climate change will decrease the benefit gained from natural cooling during the day, the opportunity exists to derive an increased benefit from night-time free cooling for centralised air conditioning systems. With thermal mass being critical to maximising the benefit of night ventilation systems, this provides an indicator of the type of construction that will be more suited to buildings in future years if an increase in energy use due climate change is to be reduced.
