摘要:

目前我国超低能耗建筑主要分布在京津冀、河南及山东等寒冷地区,少量分布在夏热冬冷地区。事实上,严寒地区也是超低能耗技术节能收益潜力较大的地区,但由于严寒地区冬季极端寒冷漫长,对保温性能要求较高,对于门窗性能、设备系统性能、保温安装安全性构成了挑战,目前在严寒地区大规模实施的超低能耗建筑实践案例仍相对偏少。针对该地区所面临的难点问题,行业急需行之有效的解决措施。以中海河山大观项目为例,提出了严寒地区超低能耗住宅项目设计要点,包括围护结构保温、外窗、热桥、气密性,冷热源系统设计及可再生能源应用等,对案例项目已有的运行数据进行了全面的分析,评估了超低能耗技术措施的实施效果。研究成果可为未来严寒地区大规模实施超低能耗建筑项目提供技术参考。

Abstract:

At present, China’s ultra-low energy buildings are mainly distributed in cold zone such as Beijing, Tianjin, Hebei, Henan and Shandong, and a few projects are in hot summer and cold winter zone. In fact, ultra-low energy consumption buildings have great benefits in severe cold zone. Due to the long and extreme cold winter, the requirements for thermal insulation performance would be higher. The severe cold climate condition would also be a challenge to the performance of doors and windows, the performance of equipment systems, and the safety of thermal insulation installation. So far, there are rarely large scale ultra-low energy consumption residential groups in severe cold zone. Regarding to the technical difficulties faced in the region, effective solutions are urgently needed for the industry. Taking the Zhonghai Heshandaguan project as an example, figures out the design essentials of ultra-low energy consumption residential projects in severe cold zone, including the design of envelope insulation, external windows, thermal bridges, air tightness, cold and heat source systems, and renewable energy applications, etc. Carries out a comprehensive analysis of the operating data of the case project, and evaluates the effect of the implementation of ultra-low energy consumption technical measures. The research results can provide technical reference for the large-scale implementation of ultra-low energy consumption building projects in severe cold zone in the future.
