How has Castlewood Ii Corp's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Castlewood Ii Corp, covering report years 2019–2020. Its ENERGY STAR score went from 73 in 2019 to 85 in 2020 (+12 points).

What does an ENERGY STAR score of 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 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. Castlewood Ii Corp's 32.2 kBtu/ft² across 79,001 sq ft works out to about 2.5 billion Btu (746 MWh-equivalent) in 2020. The disclosure also reports 471,874 kWh of electricity and 8,907 therms of natural gas for the year.
