西部地域办公建筑自然通风的节能效应研究

Study on energy conversation of office building under natural ventilation in the western region

利用Designbuilder模拟软件对西部地域九个城市的典型办公建筑在自然通风和非自然通风条件下进行逐时能耗模拟,以节能率和单位面积节能量为指标,结合通风潜力计算结果综合分析各地区的自然通风节能潜力。结果表明各热工分区的自然通风节能潜力大小依次为温和地区、严寒地区、寒冷地区,夏热冬冷地区总体不具备自然通风节能潜力,但是在过渡季节仍有一定的节能效果。

Through simulation of energy consumption for typical office buildings under natural ventilation and non natural ventilation in 9 cities of western regin, taking the energy saving rate and amount of energy saving per unit area as the index, and combining with the calculation result of ventilation potential, the paper analyzes the energy saving potential of natural ventilation in each regions, it descends temperate regions, the cold regions and the cold regions . Areas in hot summer and cold winter generally do not have the natural ventilation energy saving potential, but still has certain effect of saving energy during the transition season.
