夏热冬暖地区超低能耗居住建筑关键技术研究
Research on key technologies of ultra-low energy residential buildings in hot summer and warm winter zone
摘要:
超低能耗建筑发展十余年来,在北方地区已有大量的成功案例,积累了丰富的工程经验。随着城乡建设领域“双碳”目标的逐步落实,超低能耗建筑在夏热冬暖地区逐渐受到重视。夏热冬暖地区相对严寒、寒冷地区全年室内外温差小,夏季炎热潮湿,实施超低能耗建筑应注重隔热、遮阳、除湿、防结露发霉等。以解决实际问题为出发点,本文研究了夏热冬暖地区超低能耗建筑的关键技术,并以汕头某实验样板间项目为例,针对该气候区实际工程中存在的问题提出了解决方案,研究结果可供该气候区超低能耗建筑工程实施参考。
Abstract:
Ultra-low energy buildings have been successfully implemented in northern China for over a decade, where rich engineering experience accumulated. With the gradual implementation of the “carbon peaking and carbon neutrality” goals in urban and rural construction sector, ultra-low energy buildings in hot summer and warm winter zone are attracting increasing attention. The indoor and outdoor temperature difference in hot summer and warm winter zone is relatively smaller throughout the year comparing to severe cold zone and cold zone. In summer, it is hot and humid. Implementing ultra-low energy buildings should focus on insulation, shading, dehumidification, and prevention of condensation and mildew. Starting from solving practical problems, key technologies of ultra-low energy buildings in hot summer and warm winter zone are investigated. Taking an experimental model room project in Shantou as an example, the solutions to the problems existing in the actual project in this climate zone are proposed, which can provide a reference for the implementation of ultra-low energy building projects in this climate zone.
