The building energy consumption and outdoor design conditions of severe cold regions based on climate change

Abstract

Climate change and its effects is a topic that attracts the attention of human beings all over the world. In recent years, the extreme climate changes frequently occurring in China's severe cold regions have led to the increase in building energy consumption and decrease in the winter indoor thermal comfort. This chapter selects rural dwellings as the research object, and based on the meteorological data of Harbin in 63 years, it applies the frequency distribution analysis to obtain the extreme temperature values under different recurrence intervals; meanwhile, taking these values as the outdoor design conditions, this study simulates and compares the building energy consumption in different conditions, so as to reveal the effects of climate change on building energy consumption of heating in winter and provide the quantitative basis for the energy-saving optimization design of rural dwellings in severe cold regions.
