Building new single-family homes to zero-energy (ZE) or zero-energy ready (ZER) home standards can save consumers thousands of dollars over the home’s life cycle. ZE homes produce as much renewable energy as they consume over the course of a year, and ZER homes have similar levels of efficiency without onsite solar photovoltaics (PV). In addition, increasing market penetration of ZE homes can help cities meet their aggressive greenhouse gas emission goals while building a more futureproofed and energy-secure building stock.
Despite these benefits, ZE and ZER homes make up less than 1% of the residential market, partially due to outdated perceptions of the incremental cost for these offerings. This report demonstrates that the cost increase to build a ZE or ZER home is modest—far less than consumers, builders, and policymakers may realize—and highlights methods builders and policymakers can use to drive increased market penetration.
