MALAYSIAN WEATHER DATA (TRY) FOR ENERGY SIMULATIONS IN BUILDINGS

Detailed energy simulations for buildings in Malaysia have become possible after the recent construction of a Malaysian TRY (Test Reference Year) based on 21 years of hourly weather data from Subang Meteorological Station. The climatic parameters contained in the TRY are dry bulb temperature, wet bulb temperature, absolute humidity, relative humidity, cloud cover, wind speed, wind direction, sunshine hours, global, diffuse and beam solar radiation. The computer program TSBI3 uses the TRY to perform annual energy simulations for buildings hour by hour. The input and output are very detailed making TSBI3 a powerful tool for energy analysis and optimisation of buildings. Other applications of the TRY are manifold including energy studies for solar systems and photovoltaic architecture.
