Step-by-Step Process for Spec’ing BIPV Systems in Building Design

The most critical BIPV decision happens here—at the table, during schematic design—not on the construction site. Photo © Pexels. Step-by-Step Process for Spec’ing BIPV Systems in Building Design When a 14-storey mixed-use project in Düsseldorf added 2,200 m² of photovoltaic curtain-wall spandrels in 2024, it offset 168 MWh of annual grid purchases and shaved €62,000 off its façade material budget because the PV laminate replaced conventional insulated spandrel glass, vapour barrier, and back-pan assembly. The project team credited one decision above all others: they brought BIPV laminated glass into the conversation at the schematic design stage, before mullion centres were frozen. That timing advantage is not anecdotal. An IEA-PVPS Task […]
