PNNL

PNNL continues to enhance a national energy efficiency rating tool for commercial and multi-family residential buildings. The Building Energy Asset Score, known simply as “Asset Score,” provides information for buildings similar to what’s found in energy guides for appliances and on vehicle fuel-economy stickers. Developed at PNNL, the Asset Score combines novel modeling and whole-building energy simulation capabilities to successfully evaluate a building and its systems. As of early 2020, the software tool has been applied to more than 9,300 buildings representing nearly 1.3 billion square feet of commercial space. Asset Score was designed to be readily accessible to building owners, operators, and occupants. It is easy to use, free, relevant for existing and new structures, and requires only basic building information to obtain a rating.
