What does an ENERGY STAR score of 36 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 36 means the building performs better than about 36% of its national peers.

In New York City, 43% of scored buildings are at 75 or above.

Its source EUI of 189.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 389,755 kWh of electricity and 845 thousand gallons of water for the year.
