摘要
建筑遮阳是建筑节能的有效手段之一,可减少和控制太阳能增益、降低冷却负荷。有效的遮阳控制策略可以减少对人工照明的需求,最大限度地减少眩光并提高室内人员的舒适度、幸福感和生产力。为研究常见遮阳类型典型遮阳控制策略的防眩光、提升采光和节能潜力,基于瞬时眩光概率(IDGP)、瞬时有效照度(IUDI)和节能率三项评价指标,以济南地区办公建筑为例,借助Grasshopper软件进行建模,采用Honeybee插件进行光模拟与能耗模拟,分析遮阳卷帘、水平遮阳板、垂直百叶和水平百叶4种常见遮阳类型不同控制策略下的室内眩光、采光与建筑节能情况,并提出各类遮阳最佳逐时控制策略。结果表明,瞬时眩光概率(IDGP)、瞬时有效照度(IUDI)和节能率可以直观反映常见遮阳类型不同控制策略对室内眩光采光和建筑能耗的影响情况;选择合适的布局方式、遮阳类型及其控制策略可达到减少室内眩光、提升室内采光水平和节能效果。
Architectural shading is one of the most effective means of building energy efficiency,reducing and controlling solar gain and lowering cooling loads.Effective shading control strategies can reduce the need for artificial lighting,minimize glare,and improve the comfort,well-being and productivity of occupants.In order to study the anti-glare,improve daylighting and energy-saving potential of typical shading control strategies for common types of shading,based on the three evaluation indicators of Instantaneous Daylight Glare Probability(IDGP),Instantaneous Useful Daylight Illuminance(IUDI)and energy-saving rate.Taking the office buildings in Jinan area as an example,with the help of Grasshopper software for modelling,Honeybee plug-in for light simulation and energy consumption,the indoor glare,lighting and building energy saving under different control strategies of four common types of shading,namely,roller blinds,horizontal sunshade panels,vertical louver and horizontal louver are analyzed,and the best hourly control strategies for various shades are proposed.The results show that the IDGP,IUDI and energy-saving rate can intuitively reflect the influence of different control strategies of common shading types on indoor glare,lighting and building energy consumption.Choosing the right layout,shading type and control strategies can reduce indoor glare,improve indoor lighting levels and save energy.
