摘　　要：针对我国5个气候区,采用Comfen软件模拟量化了中空玻璃4种光热比下15种百叶工况对酒店南向外遮阳能耗密度及舒适度的影响规律。结果表明,不同气候区对取暖、制冷、通风及照明的能耗需求差别很大,而建筑能耗、室内舒适度之间相互影响。中空玻璃光热比及百叶工况对室内得热及日光照度产生很大影响,并进一步影响建筑能耗及室内舒适度,得到了不同气候区下总能耗密度、热舒适度及光舒适度各单项指标最优时的百叶工况以及中空玻璃光热比。采用CRITIC赋权法得出各气候区建筑能耗密度及室内光热舒适度的权重系数,进一步对不同工况进行了综合评分,并得出最优方案。For the five climate regions in China,Comfen was used to simulate and quantify the impact of 15 modes for venetian blind shading on the energy density and comfort level of south-facing hotel external shading under four kinds of LSG.The results show that the energy consumption demand for heating,cooling,ventilation and lighting varies greatly in different climate regions,and the building energy consumption and indoor comfort affect each other.The condition of venetian blind shading and LSG of insulating glass have a great impact on the indoor heat gain and sunlight illumination,and further affect the building energy consumption and indoor comfort.The condition of venetian blind shading and LSG of insulating glass are obtained when the total energy consumption density,thermal comfort and light comfort are respectively optimal in different climate regions.The CRITIC weighting method was used to obtain the weight coefficients of building energy consumption density and indoor light and thermal comfort level in each climate region.Furthermore,the comprehensive scores of different working conditions and the optimal scheme are obtained,
