London, U.K. — (METERING.COM) — March 11, 2009 – Representatives of the three main green building rating systems have signed a Memorandum of Understanding agreeing to work together towards aligning these standards.
The U.S. Green Building Council has developed the Leadership in Energy and Environmental Design (LEED) certification scheme. The U.K.’s BRE administers the BREEAM system. The Green Building Council of Australia has developed the Green Star rating tool.
Rating tools are a key component in the market for green building around the world, but there has been a growing demand for consistency and comparability between the tools, particularly with regards to the way they account for carbon emissions.
The agreement between the three organizations will set up a working group to map and develop common metrics to measure CO2 emissions from new homes and buildings. It will also aim to align the rating tools of each organization and provide consistency in measurement and reporting.
Buildings typically account for up to 40 percent of a country’s energy use and carbon emissions. But existing technologies such as improved insulation, energy efficient lighting and appliances can reduce energy usage and emissions substantially.
“Rating tools like BREEAM, LEED and Green Star have a proven track record in driving significant improvements in performance, and I’m delighted they are now coming together to help create an international language that will enable us to talk with one voice about the vital role green buildings can play in creating a low-carbon future,” commented Paul King, chief executive of the U.K. Green Building Council.
