New energy.

Our mission is to help our clients reduce the environmental footprint of energy use in buildings. We do this by:

  • Researching and evaluating emerging energy savings and distributed energy opportunities
  • Developing and analyzing policy and programmatic market transformation mechanisms that help accelerate widespread adoption of those opportunities
  • Embracing innovation and exploring unconventional strategies to address urgent energy and environmental challenges

Meet the team.

 

PetePeter May-Ostendorp, PhD, LEED AP O+M is a Principal and founder of Xergy. For the past decade, he has been investigating emerging energy savings opportunities in buildings. His areas of technical expertise include building energy modeling, advanced control techniques, energy monitoring and management, plug loads, and energy-related analytics and software development. He has authored dozens of publications on controls and end-use efficiency in buildings, and his research has significantly contributed to mandatory efficiency standards and voluntary labeling programs for televisions, computers, lighting, power supplies, and other fast-growing end uses. Past clients include the Natural Resources Defense Council, Natural Resources Canada, the National Rural Electric Cooperative Association, the California Energy Commission, the United States Green Building Council, and Pacific Gas and Electric Company.

Peter is a co-founder of Dartmouth Green Alumni and a member of International Building Performance Simulation Association. When he’s not thinking about energy, he enjoys exploring the splendor of the Four Corners with his wife and three children.
