建筑节能是改善广大人民的建筑环境的需要。随着现代化建设的发展和人民生活水平的提高,舒适的建筑热环境越来越成为人们生活的需要。我国气候冬冷夏热的问题是相当突出的。冬天需要采暖,夏天想要空调,而采暖和制冷都需要能源,其中对优质能源的需求量增长更快。因此,为了提高人民生活水平,为了国民经济持续、快捷、健康的发展,就必须搞好建筑节能。 Building energy efficiency is the need to improve the people’s built environment. With the development of modernization and the improvement of people’s living standards, the comfortable building thermal environment has increasingly become the need of people’s lives. The problem of the cold winter and summer heat in China is quite prominent. Heating is needed in winter, air conditioning is needed in summer, and energy is needed for heating and cooling. The demand for high-quality energy grows faster. Therefore, in order to improve the living standards of the people, and for the sustained, rapid, and healthy development of the national economy, it is necessary to do a good job of building energy conservation.
