低碳建筑设计理念与技术

The Design Concept and Technology of Low Carbon Building

针对全球气候环境日益变暖和我国建筑二氧化碳排放量比例居高形势,该文提出低碳建筑将成为建筑界的永恒课题。对低碳建筑概念进行阐述,提出自然采光与自然通风设计和太阳能得热空间与温度梯度场房间设计的低碳建筑设计理念;剖析低碳建筑技术的利用,并试算三例住宅在使用过程中二氧化碳排放量,指出要实现整个寿命周期的低碳建筑,不仅只是实现建筑使用期间的低碳,还需要从材料的生产和建造、维护与更新、拆除和重新利用等这些方面充分考虑降低能耗和二氧化碳的排放。

This paper proposes that the low-carbon building will be an eternal subject of the architecture discipline in connection with the situation that the growing global climate warming and the high percentage of building carbon dioxide emissions in china.Clarifying the concept of low carbon building,the paper proposes that the design concept of low-carbon buildings should be based on natural daylighting,natural ventilation,solar heat gain space and the room temperature gradient;analysising the use of low carbon building technology and spreadsheets the carbon dioxide emissions of three housings in duration,points out that to achieve low-carbon buildings in the whole life cycle not only means to achieve low-carbon in duration of buildings,but also should fully consider reducing energy consumption and carbon dioxide emissions in the course of the production and construction of material,maintenance and updating,removal and re-use,etc.
