西藏高原低能耗建筑设计关键技术研究与应用

针对西藏高原地区城乡居住建筑环境质量差、常规能源缺乏的现状,通过对城乡居住建筑的大规模实地勘察、对建筑物理环境和能耗等指标的详细测算以及对城镇居住建筑和传统民居基本模式的综合分析,提出了适合西藏高原自然气候条件和社会经济背景的低能耗建筑设计的基本理论、方法及其关键技术问题。研发了低能耗建筑设计基本气象参数数据,创作出以太阳能综合利用为核心技术、适合当地民族文化和社会经济发展状况的城镇节能居住建筑体系和新型乡村生态民居建筑并建成示范工程,在满足基本热舒适条件下,同时保证了居住建筑的采暖和空调的超低能耗。编制了西藏地区建筑节能设计相关标准和图集,推动了当地建筑节能行业的整体进步。研究成果对于西部其他地区亦具有借鉴意义。

Key technological research and application of low energy consumption building design in Tibe

According to the poor environment situation of residential building in Tibetan plateau both urban and rural and the shortage of conventional energy sources, this paper presents the basic theories, methods and key technical problems for low energy consumption buildings design appropriate to the local climate natural condition and the social economic background, by the means of large-scale field investigation, detailed testing and calculation on the physical environment and energy consumption and the comprehensive analysis about the basic model of residential buildings. The basic meteorological data for low energy building design are developed. The energy saving building system for city and rural and the new rural ecological residential building model, based on the local culture and social economic development condition, are proposed and designed focusing on the utilization of solar energy. Moreover, exemplary projects are built,which not only meet basic thermal comfort level, but also guarantee the super low energy consumption for heating and cooling. Design standard and atlas reference to low energy building design for Tibetan plateau are compiled, promoting the overall progress of building energy conservation. The results of this study provide an effective reference for the entire Qinghai-Tibet plateau and for other areas of the country.
