近几年,人们开始认识到一系列数字所包含的意义:目前我国既有建筑近400亿平方米,95%以上是高能耗建筑;每年城乡新建房屋建筑面积近20亿平方米,其中80%以上为高能耗建筑,单位建筑面积能源消耗为发达国家的3倍以上。到2020年,如果城镇建筑达到节能标准,每年可节省的电量相当于4.5个三峡大坝的发电量。建筑节能问题已经成为全社会关注的一个焦点,就连人民大会堂也即将进行节能改造。清华大学环境节能楼,就是在此大环境下诞生出来的示范性建筑。让我们进去看一看,这栋应用了各种先进节能技术的大楼,究竟暗藏着哪些“玄机”?
In recent years, people have begun to realize the significance of a series of figures: At present, there are nearly 40 billion square meters of existing buildings in China, and over 95% of them are high-energy buildings. Each year, the construction area of new houses in urban and rural areas is nearly 2 billion square meters, of which 80%. The above is a high-energy-consumption building. The energy consumption per unit of building area is more than 3 times that of the developed countries. By 2020, if urban buildings meet energy-saving standards, the amount of electricity that can be saved each year is equivalent to 4.5 generations of the Three Gorges Dam. The issue of building energy conservation has become a focus of concern for the entire society. Even the Great Hall of the People will soon carry out energy-saving reforms. Tsinghua University’s environmental energy conservation building is an exemplary building that was born out of this environment. Let’s go in and take a look at the “black box” hidden in this building with various advanced energy-saving technologies.
