《居住建筑节能设计标准》(DB11/891-2012)从2011年年初开始编制,目前编制工作已完成,并已获北京市规划委员会和北京市质量技术监督局批准发布,将于2013年1月1日起开始实施。这是国内第一个节能75%的地方标准,与2006年版北京市地标和现行(2010年版)国家行业标准相比较,本标准具有以下几项特点。关于节能目标和节能率居住建筑供暖能耗与基准值相比较达到的节能率(节能目标),仅仅是分析确定建筑热工、机电系统等设计参数和规定时的计算研究
The Design Standard for Energy Efficiency of Residential Buildings (DB11 / 891-2012) has been in preparation since the beginning of 2011. The compilation work has been completed and has been approved by Beijing Municipal Planning Commission and Beijing Bureau of Quality and Technical Supervision for publication in January 2013 First day of implementation. This is the first local standard of 75% energy saving. Compared with the 2006 edition of Beijing Landmark and the current (2010 edition) national industry standard, this standard has the following features. About Energy Saving Targets and Energy Saving Rates The energy saving ratio (energy saving target) achieved when heating energy consumption of residential buildings is compared with a reference value is merely a calculation study for analyzing and determining design parameters and regulations of building thermal engineering and electromechanical systems
