建筑节能就是指保证人们在舒适的环境下生活和工作,使得建筑消耗的能源尽可能少。本文从建筑节能设计中具体环节对节能建筑设计进行分析,即建筑的主空间与建筑节能设计、自然通风设计、建筑朝向设计、建筑体形系数、外墙的保温隔热性能、屋面的保温隔热性能、采暖系统的节能。 Building energy efficiency means ensuring that people live and work in comfort, making the building consume as little energy as possible. This article analyzes the design of energy-saving buildings from the concrete aspects of building energy-saving design, that is, the main space and building energy-saving design, natural ventilation design, building orientation design, building form factor, exterior wall thermal insulation performance, roof insulation Performance, energy saving heating system.
