The European Union’s commitment to fighting global warming has meant a growing trend in European countries of incorporating energy audits and ratings as part of the home sales process. Relative to other options, boosting buildings efficiency standards is usually the most attractive economic and political option to policymakers because of the large piece of the energy pie that buildings take up. (In the EU, buildings account for 40 percent of energy consumption.) As part of the European Union’s Directive on The Energy Performance of Buildings, all member countries are expected to have energy performance certificates available as part of a required information packet when a new home is sold or leased.
