The City of Boulder designed and developed the EnergySmart residential energy efficiency service in conjunction with SmartRegs, the nation’s first rental housing energy efficiency building code. The resulting services reduce many of the barriers that previously existed to making energy efficiency upgrades. This service provides a complement to SmartRegs, an energy efficiency requirement in rental housing, by providing assistance and incentives to property owners who are required to complete energy upgrades in their properties. The results achieved through both EnergySmart and SmartRegs demonstrate an innovative approach to complementing a policy requirement with assistance and funding to ease the burden of compliance.
