How does 950 W Maude (Lsnr) compare with other office buildings in California?
The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. 950 W Maude (Lsnr)'s ENERGY STAR score of 77 compares with an average of 75 across the 4,912 that report a score; it scores higher than 38% of them and lower than 61%. Its site EUI of 52.9 kBtu/ft² is roughly in line with the average of 56.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.3 kgCO₂e/ft² is roughly in line with the group average of 3.6 kgCO₂e/ft².
At 143,822 sq ft, it is roughly in line with the average floor area of 151,937 sq ft for those buildings. Its 1985 construction date is close to the group's average year built (1985). 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 77 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 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 falls in band B — above median (70–84). 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 California, 65% 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. 950 W Maude (Lsnr)'s 52.9 kBtu/ft² across 143,822 sq ft works out to about 7.6 billion Btu (2,230 MWh-equivalent) in 2024. The disclosure also reports 1,398,269 kWh of electricity and 28,427 therms of natural gas for the year.
