Abstract: The climate change and urban heat island (UHI) effects on outdoor meteorological parameters were determined by analysing design temperatures for heating and air-conditioning in urban centre, suburban and outer suburban areas in a large city in northern China. The results showed that design temperatures increased apparently over the past 20 years and decreased considerably from the urban centre to suburban and outer suburban areas. The climate change and UHI impacts would lead to 1%-5% changes in design loads, decreasing the heating design load and increasing the cooling design load as the buildings moves from outer suburban, suburban to urban areas and from the past to the present. The decrease in the heating load exceeds the increase in the cooling load, being beneficial to improve building energy efficiency. Climate change and UHI impacts should be fully considered to promote energy-saving of building design.
