Towards net zero energy for older apartment buildings in Brisbane

This paper presents initial results of ongoing research into the current condition and future value of 1960s and 1970s apartment buildings in Brisbane. Modeling tools are employed to assess hygro-thermal behaviour and energy consumption of a typical building, comparing its current and post energy retrofit performance. The feasibility of the most effective retrofit strategies is then evaluated in light of socio economic factors, and conclusions are drawn about the best future for these buildings and their inhabitants.
