Let's talk about the weather

In this paper the availability of weather data in Australasia in terms of both hourly data for energy simulations and synthesized design day data for cooling and heating load estimation is discussed. Problems in establishing suitable data as identified in recent and current work carried out by ACADS and others, together with some possible solutions are discussed. A method of extrapolating energy consumption estimates to locations where hourly climatic data is not available is presented. The possible use of energy simulation programs in an iterative mode to size heating and cooling plant is also discussed.
