目前,我国建筑能耗大的主要原因是建筑设计标准低,浪费大。要节约采暖能耗,除对采暖系统进行技术改造、提高锅炉热效率和减少管网热损失外,重点应放在改进建筑设计,加强建筑保温隔热性能,减少热损失上。常用的改进设计手法有合理规划、充分利用朝向、改进建筑体型和加强外围护结构保温隔热性能等。罔内外实践证明,提高建筑围护结构的保温隔热性能是最经济有效的节能措施。一、建筑节能设计的主要措施改善围护结构的保温隔热性能,应从 At present, the main reason for the large energy consumption in China’s buildings is the low design standard and waste. To save heating energy consumption, in addition to the technical transformation of the heating system, improve the boiler thermal efficiency and reduce the heat loss of the pipe network, the focus should be on improving the architectural design, strengthening the thermal insulation performance of the building, and reducing the heat loss. The commonly used improved design methods include reasonable planning, full use of orientation, improvement of building shape, and strengthening of thermal insulation performance of external protective structures. Practices inside and outside the country have proven that improving the thermal insulation performance of building envelopes is the most economical and effective energy-saving measure. First, the main measures for the design of energy-saving buildings to improve the thermal insulation performance of the envelope structure should be from
