They don’t say what the kWh usage is, just that the electricity cost in $$ is over $1000 on the highest month. For a unit surrounded by what should be other conditioned spaces, that’s insane to me.
A quick web search indicates that nyc $/kwh is about 31c. So that’s 3225kwh in one month! My standalone house plus pool pump, dual zone ac, and ev charger doesn’t even come close. Clearly there is a major insulation issue which is the root cause and everything else is just trying to put bandaids on an arterial bleed.
