PHI Construction System Certification

PHI Construction System Certification

PHI Component Certification for Opaque Construction Systems What is it? An “opaque construction system”, in the context of PHI’s Certified Component Database, is a collection of assemblies and junctions that make up the thermal envelope. Typical assemblies include external wall, roof, floor on basement, or slab on grade. The construction system also includes at least one specific type of window and door, along with their installation details. Where is it? As with the spread of the Passive House Standard in general, the majority of activity in certified construction systems also has its roots in Western Europe. With several more systems in the planning phase for international markets, we believe that the inevitability of standardization in construction will allow advanced building science to make its way into mainstream buildings worldwide.
