How has Mountain View Town Center I Apartments's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Mountain View Town Center I Apartments, covering report years 2019–2024. Its ENERGY STAR score was 90 in both 2021 and 2024.

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 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. Mountain View Town Center I Apartments's 38.0 kBtu/ft² across 56,804 sq ft works out to about 2.2 billion Btu (633 MWh-equivalent) in 2024. The disclosure also reports 141,429 kWh of electricity and 15,771 therms of natural gas for the year.
