It should be easy and common to compare the efficiency of one building to another, but it isn't. And because buildings use more energy than any other sector--making up 40 percent of total U.S. energy consumption--it's crucial to know where that energy is going, so we can eliminate costly waste. Several U.S. cities and states have now adopted policies that will make building performance more transparent, helping drive energy efficiency gains in the built environment. As more places follow, IMT will continue to research best practices and provide expert assistance to policymakers.
(Right: Energy benchmarking found that the New York Public Library's Central Library - Schwartzman Building has a source energy use intensity of 231.7 kBtu per square foot, better than the national average.)
35,000 buildings saved an average of 7% in energy.
The Global Buildings Performance Network (GBPN) seeks to significantly reduce greenhouse gas emissions associated with building energy use.Find out more →
