How has 640 Tenneessee's energy performance changed over time?
BuildingCensus holds 3 Denver disclosures for 640 Tenneessee, covering report years 2021–2023. Its ENERGY STAR score went from 96 in 2021 to 97 in 2023 (+1 points).

What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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 Denver, 54% 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. 640 Tenneessee's 40.0 kBtu/ft² across 40,209 sq ft works out to about 1.6 billion Btu (471 MWh-equivalent) in 2023. The disclosure also reports 109,282 kWh of electricity and 12,363 therms of natural gas for the year.
