摘要
为研究建筑围护结构属性对同一热工分区不同城市节能建筑负荷影响的敏感性,以同属于寒冷地区的兰州和郑州为研究目标所在城市,在节能65%的前提下将4种外墙、3种外窗和4种窗墙比进行组合得到了48个可能的办公建筑围护结构计算房间。分别计算了这些房间的冷负荷、热负荷和全年总负荷并分析了各热工参数对负荷的影响。通过与基准房间负荷对比,获得了具有不同热工性能的计算房间的节能率及最优的办公建筑围护结构。
Abstract
Two cities located in cold zone,Lanzhou and Zhengzhou were selected to study the relationship between the building envelope properties and the building heating and cooling load.Under the condition of energy efficient rate 65%,four types of walls,three types of windows and four window-to-wall ratios were assembled into 48 types of office building envelopes as the calculating rooms.The annual heating and cooling loads of the calculating rooms were obtained and the influence of thermal performance on building load was analyzed.The energy saving ratio and the optimal building envelope for each city were determined by comparing with the annual total load of baseline room,.
