Remodeling or retrofitting existing homes to become more energy efficient and as close to net zero as possible, is just as feasible as building new zero energy homes. In fact, there are ample opportunities to turn existing standard homes into near zero energy, zero energy ready or zero energy homes. By retrofitting the existing inventory of homes, we can move rapidly towards a carbon-free future. In addition to the many environmental benefits and energy and financial savings, energy efficiency upgrades increase the overall value of a home. Financing these upgrades is sometimes a challenge, but there are several available options for homeowners and contractors to consider. And now there are FHA loans that are available for energy upgrades and renewable energy retrofits in every state of the country.
