摘　　要：室外计算参数作为连接室外气候和围护结构热工设计的重要桥梁,其覆盖区域的广度与统计时段的时效性将对围护结构保温设计起到至关重要的作用。本文以GB 50176—2016《民用建筑热工设计规范》围护结构保温设计室外计算参数为研究对象,梳理其统计计算方法,分析其在统计年限更新前后的变化趋势和分布规律,获得了室外参数变异对围护结构保温设计最小热阻值的影响规律,为GB 50176—2016《民用建筑热工设计规范》中室外计算参数的更新提供基础支撑。As a bridge between outdoor climate and the thermal design of building envelopes,outdoor design conditions are very important.The width of their coverage area and the timeliness of their statistical period will play a crucial role in the thermal insulation design of building envelopes.This paper,using the outdoor design conditions of thermal insulation design of building envelope in(GB 50176—2016)Code for thermal design of civil buildings as the research objects,combined their statistical calculation method,analyzed their change trend and distribution law before and after statistical years updating,and obtained the influence law of outdoor parameters variation on the minimum thermal resistance value of thermal insulation design of building envelope.aiming to provide basic support for updating outdoor calculation parameters in the(GB 50176—2016)Code for thermal design of civil buildings.
