Questar Gas provides incentives for home builders to construct energy efficient homes. Rebates are provided for energy efficient gas equipment. Builders can also receive whole house rebates for building Energy Star homes (certified by an eligible home rater) and High Performance homes (that exceed the 2009 IECC standards). All equipment and construction requirements must be met in order to participate. The program application, builder participation agreement, and more details about incentive amounts and efficiency requirements are located on the program web site.
