Its site EUI of 34.9 kBtu/ft² is about 60% below the average of 87.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 283,072 sq ft, it is about 24% above the average floor area of 227,860 sq ft for those buildings. It was built in 1970, 4 years earlier than the group's average year built (1974).

What does an ENERGY STAR score of 91 mean?

ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In Washington, DC, 47% of scored buildings are at 75 or above.

Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. 2015 Massachusetts Avenue NW's 34.9 kBtu/ft² across 283,072 sq ft works out to about 9.9 billion Btu (2,895 MWh-equivalent) in 2012. Its source EUI of 102.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,377,644 kWh of electricity and 17,592 therms of natural gas for the year.

Which law requires 2015 Massachusetts Avenue NW to report its energy use?

The record shown here is the report-year 2012 disclosure (source record dc:PM3510066:2012). DC's Building Energy Performance Standards (BEPS) require buildings below the performance standard to improve over compliance cycles (the first ends December 31, 2026; later cycles run five years), with penalties for buildings that fail to meet their pathway.
