Bromine

How does Bromine compare with other office buildings in Washington, DC?

The latest disclosures cover 899 office buildings in Washington, DC, out of 6,870 buildings citywide. Bromine's ENERGY STAR score of 27 compares with an average of 70 across the 774 that report a score; it scores higher than 5% of them and lower than 94%. Its site EUI of 83.4 kBtu/ft² is about 50% above the average of 55.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 11.2 kgCO₂e/ft² is about 124% above the group average of 5.0 kgCO₂e/ft².

At 31,150 sq ft, it is about 86% below the average floor area of 216,135 sq ft for those buildings. It was built in 1982, 8 years later than the group's average year built (1974). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².

What does an ENERGY STAR score of 27 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 27 means the building performs better than about 27% of its national peers. BuildingCensus bands the score into report-card grades; 27 falls in band D — lowest band (1–54). It sits 48 points below 75, the threshold for ENERGY STAR certification. 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. Bromine's 83.4 kBtu/ft² across 31,150 sq ft works out to about 2.6 billion Btu (761 MWh-equivalent) in 2014. Its source EUI of 261.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 761,396 kWh of electricity, 0 therms of natural gas and 1,008 thousand gallons of water for the year.

Which law requires Bromine to report its energy use?

Bromine reports under the Clean and Affordable Energy Act / BEPS, the legal basis of Washington, DC's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2014 disclosure (source record dc:PM4372707:2014). 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.
