U.S. For the purpose of reducing energy use in new homes by more than 50%, the California Energy Commission adopted building standards that require solar photovoltaic systems starting at 2020.
The new energy efficiency standards are the first in the nation to require solar power. They will reduce greenhouse gas emissions by an amount equivalent to taking 115,000 fossil fuel vehicles off the road.
The energy efficiency standards of 2019 buildings will in effect be 1's January 2020, and focus on four key areas: residential intelligent photovoltaic systems, updated thermal envelope standards (avoiding heat transfer from the interior to the exterior and the vice versa), residential and non-residential ventilation requirements, and non-residential lighting requirements. For the first time, the standards also establish requirements for recently constructed health facilities.
"Under these new standards, buildings will perform better than ever, while at the same time contributing to a reliable network," said Commissioner Andrew McAllister, who is the leader of the Energy Efficiency Commission. "The buildings that Californians buy and live in will run very efficiently while generating their own clean energy, it will cost them less to operate, they will have healthy indoor air and provide a platform for" smart "technologies that will push the state even further down the road to future of low emissions ".
Under the new standards, non-residential buildings will use approximately 30 percent less energy due mainly to lighting upgrades. For owners of residential homes, based on a mortgage of 30 years, the Energy Commission estimates that the standards will add about $ 40 to an average monthly payment, but will save consumers $ 80 on monthly bills for heating, cooling and illumination.
