The 2002 Energy Performance of Buildings Directive (EPBD) was implemented in Spain through the 2009 Basic Energy-Saving Document of the Technical Building Code (CTE-DB-HE). The 2010 EPBD was initially implemented through the 2013 CTE-DB-HE and, later, through the future CTE-DB-HE. The 2009 CTE-DB-HE required the thermal envelope to comply with thermal transmittance limits and a minimum solar contribution for domestic hot water (DHW). The 2013 CTE-DB-HE requires, in addition to a minimum DHW solar contribution, compliance with certain limits on energy demand for heating and cooling and on the consumption of non-renewable primary energy. Finally, the future CTE-DB-HE requires a certain global heat transfer coefficient and solar control for the thermal envelope, a minimum contribution of renewable energy for DHW and a limit on the consumption of both non-renewable primary energy and primary energy. In this paper, the energy and environmental impact on a single-family house in Logroño (La Rioja) built in compliance with the different building regulations is studied. Thus, the implications, in terms of energy savings and efficiency, associated with the evolution of these regulations towards nearly zero-energy buildings are described.
