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

Building-integrated photovoltaics (BIPV) replace conventional building-envelope materials — roof tiles, facade cladding, skylight glazing, spandrel panels — with components that simultaneously protect the building interior and generate electricity. The IEA-PVPS Technical Guidebook defines BIPV as photovoltaic products that “serve as a building element and generate electricity,” distinguishing them from building-applied photovoltaics (BAPV), which are mounted on top of an existing envelope. This distinction is more than semantic: it means a BIPV product must satisfy both photovoltaic module standards (IEC 61215, IEC 61730) and building-construction standards (fire, structural, weatherproofing) simultaneously — a dual compliance burden that shapes every specification decision. Integrating BIPV early in the design process — during the schematic […]
