Climate change adaptation pathways for Australian residential buildings
Abstract Climate change can significantly impact on the total energy consumption and greenhouse gas (GHG) emissions of residential buildings. Therefore, climate adaptation should be properly considered in both building design and operation stages to reduce the impact. This paper identified the potential adaptation pathways for existing and new residential buildings, by enhancing their adaptive capacity to accommodate the impact and maintain total energy consumption and GHG emissions no more than the current level in the period of their service life. The feasibility of adaptations was demonstrated by building energy simulations using both representative existing and new housing in eight climate zones varying from cold, temperate to hot humid in Australia. It was found that, in heating dominated climates, a proper level of adaptive capacity of residential buildings could be achieved simply by improving the energy efficiency of building envelop. However, in cooling dominated regions, it could only be achieved by introducing additional measures, such as the use of high energy efficient (EE) appliances and the adoption of renewable energy. The initial costs to implement the adaptations were assessed, suggesting that it is more cost-effective to accommodate future climate change impacts for existing and new houses by improving building envelop energy efficiency in cooling dominated regions, but installing on-site solar PVs instead in heating and cooling balanced regions.
Highlights ► This study identified cost-effective climate change adaptation pathways for Australian housing. ► In heating dominated climates, adaptation can be fulfilled by energy efficient building envelop. ► More should be used in cooling dominated climates, such as efficient appliances and renewable. ► Improving building thermal envelope efficiency is cost-effective in cooling dominated regions. ► On-site solar PV is currently more cost-effective instead in heating and cooling balanced regions.
