据联合国环境署的统计数据,建筑能耗占到城市公共机构能耗的70%以上;而来自北京卫星制造厂的数据,如今广泛使用的以冷冻站为主体的中央空调占到建筑能耗的40%以上。根据住建部发布的《“十二五”建筑节能专项规划》,到“十二五”期末,建筑节能形成1.16亿吨标准煤节能能力的目标。实现的方式包括发展绿色建筑,供热体制改革,公共建筑节能以及推动可再生能源与建筑一体化应用。 According to the United Nations Environment Program statistics, building energy consumption accounts for more than 70% of the city’s public institutions’ energy consumption; while data from Beijing Satellite Manufacturing Plant, the widely used central air- 40% or more. According to the “Twelfth Five-year Plan for Building Energy Conservation” issued by the Ministry of Housing and Urban-Rural Development and the end of the “Twelfth Five-Year Plan” period, building energy conservation will form the target of energy saving of 116 million tons of standard coal. Ways to achieve include the development of green buildings, heating system reform, energy efficiency in public buildings and the promotion of integrated renewable energy and building applications.
