The Building Asset Rating (BAR) pilot is a collaborative effort of the Massachusetts Department of Energy Resources (DOER) and Northeast Energy Efficiency Partnerships (NEEP). The two phase pilot is designed to support development of innovative methods to generate building energy ratings as a means to encourage increased investment in the energy efficiency of commercial office buildings. More information on the pilot's phased approach is available on the DOER website .  

The BAR pilot builds upon DOER’s 2010 White Paper, An MPG Rating for Commercial Buildings, which addresses design considerations needed to develop a building energy rating system. Through the BAR pilot, DOER and NEEP seek to test groundbreaking methods to create an “asset” rating for office buildings that:

  • provide a whole-building energy analysis
  • consider the performance of the major energy uses within a building, such as the lighting, heating, and cooling systems.

The proposed Building Asset Rating is similar to a miles-per-gallon (MPG) rating for cars or a food nutrition label and would allow an “apples-to-apples” comparison between buildings. Such information could be valuable for real estate market actors in the commercial office building sector where buildings may change owners, investors, and tenants frequently.

Building energy disclosure on an annual basis using Energy Star Portfolio Manager is increasingly being required by major US cities. The City of Boston announced that they will be rolling out a building energy disclosure ordinance by property owners.

Where Energy Star Portfolio Manager provides an excellent annual snapshot of total annual energy use, the BAR pilot is designed to provide greater detail on how and where a building uses energy to help hone in on energy efficiency investment opportunities, and leverage the nation leading energy efficiency incentives available to commercial properties in our state.

Information learned through the Building Asset Rating (BAR) pilot will be shared with the U.S. Department of Energy (DOE) / Pacific Northwest National Laboratory (PNNL) and the State of California  These entities conduct complementary work that will inform the BAR pilot. More information about the DOE / PNNL project  and PNNL market research related to an asset rating program is available online.
