Blue Rock Village's ENERGY STAR score of 79 compares with an average of 82 across the 9,612 that report a score; it scores higher than 31% of them and lower than 68%. Its site EUI of 32.5 kBtu/ft² is roughly in line with the average of 34.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.0 kgCO₂e/ft² is roughly in line with the group average of 2.1 kgCO₂e/ft².
At 470,602 sq ft, it is about 212% above the average floor area of 150,919 sq ft for those buildings. Its 1988 construction date is close to the group's average year built (1988).

How has Blue Rock Village's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Blue Rock Village, covering report years 2019–2024. Its ENERGY STAR score went from 76 in 2019 to 79 in 2024 (+3 points); its best year on file was 2022, at 81. Site EUI moved from 37.2 kBtu/ft² (2019) to 32.5 kBtu/ft² (2024), a 13% decrease. Reported emissions went from 1,050 tCO₂e to 933 tCO₂e over the same span (down 11%).
What does an ENERGY STAR score of 79 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 79 means the building performs better than about 79% of its national peers. BuildingCensus bands the score into report-card grades; 79 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. Blue Rock Village's 32.5 kBtu/ft² across 470,602 sq ft works out to about 15.3 billion Btu (4,482 MWh-equivalent) in 2024. The disclosure also reports 2,272,946 kWh of electricity and 78,792 therms of natural gas for the year.
Which law requires Blue Rock Village to report its energy use?
