建筑是人类生产和生活的重要物质基础,也是国民经济中耗能最多的产品。重视建筑节能,意义重大。但建筑节能成效并不是轻而易举所能得到的。它的取得,除了需要技术、材料外,还需要投资、需要时间。这即是说建筑节能的效益不仅要反映在能源的节省上,同时还要保证有好的投资效果,这才是建筑节能的目的。为此,加强建筑节能技术经济研究,推 Architecture is an important material basis for human production and life, and it is also the most energy-consuming product in the national economy. Emphasis on building energy efficiency is of great significance. However, building energy efficiency is not easily attainable. Its acquisition, in addition to the need for technology and materials, also requires investment and time. This means that the benefits of building energy conservation should not only be reflected in the energy savings, but also ensure good investment results. This is the purpose of building energy conservation. To this end, strengthen the economic research of building energy-saving technologies and push
