The service from the National Renewable Energy Laboratory (NREL) provides a repository of standardized data about features commonly found in buildings. It service the needs of architects, designers, and construction personnel to create models of building energy use over time. Data for individual building components describe energy performance characteristics of windows, doors, walls, etc. matched to weather information.
API methods support search for specific building components either by type or keyword. Returned data provides descriptive facets to help narrow a search. Methods allow download of performance profiles for selected components for incorporation in an energy model for a building as a whole.
