The map represents an estimate of the total annual building energy consumption at the block level and at the tax lot level for New York City, and is expressed in kilowatt hours (kWh) per square meter of land area. A mathematical model based on statistics, not individual building data, was used to estimate the annual energy consumption values for buildings throughout the five boroughs. To see the percentage break down of the estimated end-uses, hover over or click on a block or tax lot. The tax lot level data shows how much energy an average building of that size and type would use.
I think it is a really interesting approach to get information about the energy consumption if no data on the house level is available. I hope we can meet with them while we are in New York.
