How does CNBB compare with other office buildings in Washington, DC?
The latest disclosures cover 899 office buildings in Washington, DC, out of 6,870 buildings citywide. CNBB's ENERGY STAR score of 69 compares with an average of 70 across the 774 that report a score; it scores higher than 34% of them and lower than 64%. Its site EUI of 53.4 kBtu/ft² is roughly in line with the average of 55.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 5.4 kgCO₂e/ft² is roughly in line with the group average of 5.0 kgCO₂e/ft².
At 259,162 sq ft, it is about 20% above the average floor area of 216,135 sq ft for those buildings. It was built in 1917, 57 years earlier 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.
How has CNBB's energy performance changed over time?
BuildingCensus holds 5 Washington, DC disclosures for CNBB, covering report years 2014–2018. Its ENERGY STAR score went from 68 in 2014 to 69 in 2018 (+1 points); its best year on file was 2017, at 82. Site EUI moved from 68.7 kBtu/ft² (2014) to 53.4 kBtu/ft² (2018), a 22% decrease. Reported emissions went from 2,396 tCO₂e to 1,401 tCO₂e over the same span (down 42%).
What does an ENERGY STAR score of 69 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 69 means the building performs better than about 69% of its national peers. BuildingCensus bands the score into report-card grades; 69 falls in band C — below median (55–69). It sits 6 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. CNBB's 53.4 kBtu/ft² across 259,162 sq ft works out to about 13.8 billion Btu (4,056 MWh-equivalent) in 2018. Its source EUI of 149.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,054,184 kWh of electricity, 0 therms of natural gas and 5,378 thousand gallons of water for the year.
Which law requires CNBB to report its energy use?
CNBB 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 2018 disclosure (source record dc:PM3762218:2018). 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.
