ABSTRACT (Maximum 200 words) This report describes the building code requirements and impediments to applying photovoltaic (PV) and solar-thermal technologies in residential buildings (one- or two-family dwellings). It reviews six modern model building codes that represent the codes to be adopted by most locations in the coming years: International Residential Code, First Draft (IRC), International Energy Conservation Code (IECC), . . .
. . .  installation of rooftop photovoltaic panels and solar hot-water collectors involves many overlapping issues. Roof loading, weather tightness, mounting systems, roof penetrations, and similar concerns are identical for both technologies. If such work can be coordinated, organizations supporting both technologies could work together to implement the appropriate revisions and additions to the codes. 15. NUMBER OF PAGES 14.
