Abstract
Future hourly Typical Meteorological Year (TMY) weather file is a prerequisite for utilization of building energy simulation software to estimate the impact of global climate change on building energy demand. On basis of Intergovernmental Panel on Climate Change - IPCC's latest predictions, this paper produces future TMYs of three representative cities in different climate regions in China from 2000 to 2089 including five time spans, in the form of EnergyPlus weather file format – EPW. With application of a statistical downscaling method – Morphing, estimated monthly climate change data, calculated by selected General Circulation Model (GCM) under Representative Concentration Pathways (RCPs, the latest future climate scenarios developed by IPCC in 2007), are integrated with local existing TMYs to achieve new TMYs' generation. Building energy demand by 2100 is predicted for three cities by using corresponding new TMYs as input of prototypical building models for annual energy simulation. Considering many uncertainties in IPCC's research, the predicted energy demand in Shanghai is revised by comparing predicted monthly weather data to observed data from 1961 to 2010. Keywords: climate change, Typical Meteorological Year (TMY), building energy demand, building energy simulation
