Its site EUI of 49.0 kBtu/ft² is roughly in line with the average of 51.1 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.1 kgCO₂e/ft² is about 18% below the group average of 3.8 kgCO₂e/ft².

At 31,980 sq ft, it is about 77% below the average floor area of 136,346 sq ft for those buildings. Its 1967 construction date is close to the group's average year built (1965).

What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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. Wilmington Properties Investment Group LLC's 49.0 kBtu/ft² across 31,980 sq ft works out to about 1.6 billion Btu (459 MWh-equivalent) in 2024. Its source EUI of 78.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 143,099 kWh of electricity, 10,775 therms of natural gas and 3,306 thousand gallons of water for the year.

Which law requires Wilmington Properties Investment Group LLC to report its energy use?

The record shown here is the report-year 2024 disclosure (source record dc:PM54440892:2024). 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.
