Where We Work

IMT seeks out and promotes best practices that advance buildings' energy efficiency. We favor practices that are transferable, adaptable, and scalable—so they are not limited to success in just one place or at a single level of government. As a small organization, we try to leverage our work for maximum impact, seeking out opportunities to make broad, pragmatic changes, and often working in collaboration with our partners. We also work closely with leaders and officials as they tailor policies to fit local needs, and we often assist them in implementation. Below are some of IMT's recent activities that span from local to global.


IMT has offered expert assistance to officials in numerous U.S. cities that are implementing building energy benchmarking (rating) and transparency laws, including Austin, Texas; Philadelphia; New York City; San Francisco; Seattle; and Washington, DC.

Under the City Energy Project, a joint initiative between IMT and the Natural Resources Defense Council, we are working with leaders in 10 U.S. cities to develop locally tailored energy efficiency packages that improve the performance of large buildings to create healthier cities. Under this program, we are working with the Mayors and thought leaders of Atlanta, Boston, Chicago, Denver, Houston, Kansas City, Mo., Los Angeles, Orlando, Philadelphia, and Salt Lake City.

New York City: IMT staffer Ufei Chan works full-time with the New York City government on initiatives related to the Greener, Greater Buildings Plan (GGBP). As a benchmarking manager for the PlaNYC GGBP, Ufei works in the New York City Department of Buidings and oversees compliance efforts for Local Law 84, which requires building owners to annually submit their buildings' energy use data to the City. 

Washington, DC:

  • IMT is one of the teaming members of the DC Sustainable Energy Utility (DCSEU), which helps District households, businesses, and institutions save energy and money through energy efficiency and renewable energy programs. IMT's Market Transformation efforts for the DC SEU are led by staffer Megan Houston.
  • IMT's executive director, Cliff Majersik, serves on DC's Green Building Advisory Council.
  • While on IMT's staff, Marshall Duer-Balkind worked full-time at the District Department of the Environment, managing Washington, DC’s energy benchmarking program and collaborating with other cities to share best practices. (He is still performing the same role, but now as a member of the department's staff.)
  • IMT advised on the crafting of the District's  Clean and Affordable Energy Act of 2008.
  • We helped craft the District's Green Building Act  of 2006.


United States:

  • IMT helped draft and form the coalition behind the SAVE Act, S. 1737, introduced in the U.S. Congress in October 2011 by Sens. Bennet (D-Co.) and Isakson (R-Ga.). The SAVE Act would improve the quality of mortgage underwriting by factoring in energy costs—which would reward homebuyers for choosing efficiency, and spur the construction of efficient homes and high-efficiency renovations.
  • IMT has helped develop and secure approval for provisions amending national model building standards like the International Energy Conservation Code (IECC), the International Green Construction Code (IgCC), and ASHRAE 189.1. We have presented to code committees, attended professional hearings to lobby for greener amendments, and submitted comments on building energy standards.
  • IMT provided assistance to the U.S. General Services Administration (GSA), one of the nation's largest tenants, as it revised its green-lease provisions in 2011.


IMT is the United States hub of the Global Buildings Performance Network, whose mission is to significantly reduce greenhouse gas emissions associated with building energy use. With four hubs (in Washington, Brussels, Beijing, and New Delhi) and a global headquarters in Paris, the GBPN:

  • Promotes best practices in building energy efficiency and performance
  • Offers world-class energy efficiency expertise to policy makers and business leaders
  • Advances policies and programs that promote low carbon, energy-efficient buildings worldwide

Jayson Antonoff directs the U.S. hub  and much of IMT's current work on energy code compliance and building energy performance policy is carried out in collaboration with our GBPN partners. Visit to learn more.
