US cities try 'benchmarking' to make buildings save more energy
'Benchmarking' motivates owners to rehab their buildings to save energy, carbon emissions, and fuel costs.
Humans are an increasingly urbanized species; for the first time in history, more people live in cities than in rural areas.Skip to next paragraph

And that, of course, means more buildings, which means more concentrated energy usage.
Many cities are trying to limit carbon emissions by monitoring energy use to keep it at sustainable levels. A new monitoring approach, called “benchmarking," counts on a combination of raising awareness, motivating people through comparative measures, and fostering a sense of responsibility to help building owners be greener.
The idea behind benchmarking is that measuring and rating a building’s energy performance, and making that information available in certain contexts, can help owners identify ways to increase building energy efficiency and lower energy costs.
The key to the program’s success is its emphasis on transparency – even though the information is not completely public.
“Benchmarking creates awareness,” said Jayson Antonoff, Seattle’s program manager for the benchmarking and reporting initiative. After a building owner has done benchmarking, any current or potential tenant, buyer, or lender can request to see the energy performance report, so they can make informed decisions on using the building.
“We’re trying to get the framework in place so that the market can motivate building owners to improve energy performance,” added Antonoff.
In Seattle, the city sent out letters to the owners of 8,000 buildings a few weeks ago, notifying them that they need to begin benchmarking and reporting the energy use of their buildings. In this initial phase, nonresidential buildings over 50,000 square feet will be obliged to comply with the program. The next phase will require nonresidential buildings over 10,000 square feet and multifamily buildings with five or more units to benchmark and report by April 2012.
To assist building owners, Seattle’s city government has developed educational materials, including hands-on training workshops, webinars, and a “how to” guide on benchmarking, as well as information packets on utility energy-saving programs. The city has also partnered with local utilities to provide owners with the building energy consumption data they need.
