The remarkably detailed map [columbia.edu] developed by the Modi Research Group of the Earth Institute at Columbia University reveals the total annual building energy consumption of New York, at both the block and ‘taxlot’ level (which is nearly at building level).
The map was built using MapBox. The total energy consumption is expressed in kilowatt hours (kWh) per square meter of land area. The data actually was not retrieved from utility companies, but calculated via an elaborate statistical model that is based on current large-scale estimates (e.g. the average energy use by ZIP code) in addition to lower-scale, estimated parameters (like the type and size of the building). Hovering over individual blocks or lots shows more detailed information, such as the type of energy being used, for which purpose (e.g. heating and cooling, electricity or hot water) and in what quantity.
