BOULDER - The city of Boulder is looking for more commercial building owners to participate in the energy benchmarking pilot program.

In exchange, building owners will receive free assistance from an independent energy coach who will help collect energy use data and rate their buildings' energy performance using the Energy Star Portfolio Manager, a national standard energy rating tool developed by the U.S. Environmental Protection Agency.

Portfolio Manager can help compare a building's energy use to similar buildings nationwide and provide a rating that can serve as a starting point for understanding whole building energy performance and identifying energy-efficiency upgrades that could save money.

To participate in the pilot program, contact Elizabeth Vasatka, the city's business sustainability coordinator, at 303-441-1964 by Friday, Nov. 23. For more information about the city's commercial energy efficiency strategy, visit www.bouldercolorado.gov/lead.
