Discussion on the potential impact of the energy certificate on existing housing: the UK as a case study

In 2003 the European Commission introduced the Energy Performance of Buildings Directive (EPBD) in recognition of the importance of energy savings in the urban housing stock. One of the key elements described in the Directive is the introduction of energy certificates in a property transaction. This article discusses the anticipated efficiency and effectiveness of the application of the energy certificate on the existing building stock in the UK. The thesis for discussion is that although energy certificates as a communication instrument for household appliances have appeared to be relatively successful, the different nature of the building sector can mean their effectiveness here will be rather limited. Incentives need to be introduced to support taking up the improvements recommended by the energy certificate. Effective results can probably be expected from introducing regulations combined with energy certificate standards, but it requires a rather drastic approach and needs time to receive sufficient commitment.
