How has MB OFFICE LLC's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for MB OFFICE LLC, covering report years 2022–2024. Its ENERGY STAR score went from 86 in 2022 to 88 in 2024 (+2 points).

What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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 New York City, 43% 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. MB OFFICE LLC's 53.0 kBtu/ft² across 43,220 sq ft works out to about 2.3 billion Btu (671 MWh-equivalent) in 2024. Its source EUI of 103.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 349,157 kWh of electricity, 11,010 therms of natural gas and 335 thousand gallons of water for the year.
