Bandalux Simulation Shows Exterior Solar Shading Can Cut HVAC Energy Use by 70%
In an article dated October 12, 2026, Agustina Iñiguez on ArchDaily highlights the critical role of solar shading in building design. As heat waves become more frequent, architects are prioritizing strategies to avoid overheating while still allowing natural light and views. Structures with extensive glass facades, such as west-facing office buildings, experience the highest cooling demands during the afternoon. Bandalux conducted an energy simulation for a 9-square-meter space in Madrid, revealing a 70% decrease in HVAC energy consumption when an exterior shading system is utilized. The piece explores the advantages of different fabrics, their placement, and automation for solar energy management, featuring Bandalux's Lynx app for motorized solutions across various building types.
