NYC Energy Use by Tax Lot

New Yorkers can now compare their building's energy use with other properties across the five boroughs using an interactive map. Bianca Howard, a PhD student in mechanical engineering at Columbia University, created the map using publicly available utility data. The interactive map shows data at the tax parcel level, as well as block level, depending on how far you zoom in. Data is provided for not just electricity, but also heating, cooling and hot water heating. Electricity use is reported in kilowatt hours; gas and fuel oil use, in therms. For most properties, occupants expend the most energy on heat.

This is a remarkable set of data, especially for a city that once gave up on metering water. A logical next step, and one recommended by several who commented on Howard's site, would be to normalize this data by building floor area. In theory, this would reveal which buildings are more efficient, either by massing, weatherproofing or a combination of both. As is, the data shows a strong correlation with building size and height - Midtown skyscrapers at the high end, outer borough townhomes at the low end.

It would be great to see this data for other cities. Thanks to Jessi for sharing via Gizmodo.
