COURTESY OF COLUMBIA UNIVERSITY Color-Coded Computed using city data, the map breaks down energy use into four categories: space heating, space cooling, electricity and hot water. Researchers at Columbia University's school of engineering have laun-ched a public, online catalog of all New York City buildings, each characterized by estimated energy consumption based on size and use.When users mouse over the interactive map, pop-ups present energy consumption estimates for individual buildings. The estimates are derived from a formula that multiplies square footage by the building type, such as single- or multifamily residential, business, school or industrial. Energy consumption is broken down
The growing need to collect, store and analyze the huge volumes of data collected from infrastructure project stakeholders is generating a new growth area for construction-sector firms, IT vendors and professionals.
