Energy-efficiency standards overview
Energy codes, for example, contain standardized building specifications that are intended to achieve a minimum level of energy-efficiency. Like building codes, most energy codes apply to new construction and rehab projects that exceed stated thresholds related to cost or scope. In built-out communities with little available land, requirements that apply when buildings are sold may be a more effective way to reduce residential energy consumption. These policies require certain energy-efficiency standards to be met when a property changes hands. To limit the financial impact on property owners, point-of-sale requirements typically include a ceiling on the value of repairs that must be completed in connection with a single home sale, which may be expressed as a flat dollar amount or a share of the building’s value.
