Metal Mesh as Shading Devices and Thermal Response of an Office Building: Parametric Analysis

摘要

Windows are the most important part of the building façade to control solar gains, thermal losses and visual\udcomfort. Office buildings usually have medium-high WWR (window to wall ratio value) and high internal gains\ud(due to users, lighting and appliances). For this reason, they require a good balance between thermal and visible\udperformances of transparent façades and shading control strategies to avoid overheating, optimizing daylighting\udaspects. A sensitivity analysis was assessed to evaluate primary energy use for heating, lighting and cooling for\udconventional Italian single office units equipped with static metal mesh shading devices with different geometries\udand openness factor values. Different location (Milan, Palermo), orientation (south and west) and WWR (33% and\ud100%) were analyzed. Hence shading devices alternatives as venetian blinds and sun control windows are proposed\udas a comparison.
