GTI is working to influence code and regulatory initiatives and the public review process regarding total fuel cycle impacts. With support from the Carbon Management Information Center (a gas industry collaborative), GTI has provided important technical information regarding the benefits of source energy—which measures energy consumption from the point of origin to the point of use and includes energy losses that occur with conversion and distribution—and greenhouse gas methodologies. In 2011, the U.S. DOE announced a statement of policy adopting full-fuel-cycle measures of energy use in its Energy Conservation Standards Program used for national impact analyses. Source energy is now included in the final version of the International Green Construction Code (IgCC), published in the spring of 2012. GTI is working with the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) to include source energy in a suite of major building codes.
