中国工程院院士、清华大学建筑节能研究中心教授江亿在第十一届国际绿色建筑与建筑节能大会主论坛上作了题为《实现我国北方城镇供暖节能减排的途径》的主题报告。江亿院士指出,北方城镇供暖能耗约占全国建筑能耗总量的四分之一,节能潜力巨大。我国热改不能真正实施,不是缺少政策机制,而是缺少合适的技术路线。为此,必须降低末端供暖热量需求,降低单位面积能耗,提高热源效率,降 Chinese Academy of Engineering, Tsinghua University Building Energy Research Center Professor Jiang Yi in the Eleventh International Conference on Green Building and Energy-saving Conference made a speech entitled “to achieve China’s northern urban heating energy-saving emission reduction channels,” the keynote speech. Jiang Yi academicians pointed out that the northern town heating energy consumption accounts for about a quarter of the national total building energy consumption, huge potential for energy conservation. China’s reform can not be implemented real heat, not a lack of policy mechanisms, but the lack of appropriate technical line. To this end, we must reduce the demand for heating the end of the heat, reduce energy consumption per unit area, improve heat efficiency, reduce
