建筑领域存在着严重的信息不对称,建筑节能突出的外部经济性以及明显的公共产品特性,直接影响了相关主体的积极性,是建筑节能进展缓慢的根本原因。考虑了外部成本和外部收益的建筑节能行为分析,是制定相关促进政策的出发点和归宿。 There are serious information asymmetry in the field of construction, prominent external economy of building energy efficiency and obvious public product characteristics, which directly affect the enthusiasm of the relevant subjects and is the fundamental reason for the slow progress of building energy conservation. An analysis of building energy efficiency that takes into account external costs and external benefits is the starting point and end-result of the development of the relevant promotion policies.
