巢北地区公共建筑自然通风节能潜力分析

Analysis of Energy Saving Potential of Natural Ventilation for Public Buildings in Chaobei Area

以巢北地区某高校教学楼为工程实例研究公共建筑自然通风节能潜力.通过设置不同通风工况,用DeST模拟建筑全年累计能耗,得出该地区公共建筑最佳通风工况.结果表明:通过合理使用自然通风可以减少建筑能耗,达到节能效果;模拟分析中发现通过改变自然通风工况在全年建筑负荷趋势上并无明显改变,但对于全年总负荷的数值还是有着至关重要的影响.

A teaching building in Chao Bei is taken as an example to study the natural ventilation and energy saving potential in public buildings in this paper.By setting different ventilation conditions,the optimal ventilation conditions of public buildings in the area are obtained by using the cumulative energy consumption with DeST.The study found that the reduction of building energy consumption can be realized by rational use of natural ventilation.When natural ventilation used,building energy consumption is significantly lower than that of building energy without ventilation.The simulation analysis found that changing the natural ventilation conditions did not significantly change the annual building load trend,but it still critically affected the data of the annual total load.
