The Executive Order no 909 of 18 August 2011 is amending Executive Order no. 810 of 28 June 20-10 on Publication of the Danish Buidling Regulations 2010 (BR10) as amended by Executive Order no. 1309 of 29 November 2010 and Executive Order no. 792 of 29 June 2011.

 

The Executive Order comprises provisions to implement parts of the Directive 2002/91/EC of the European Parliament and of the Council of 16 December 2002 on the energy performance of buildings (buildings directive), Official Journal of the European Union 2003 no. L 1, p. 56, as most recently amended by Directive 2010/31/EU of the European Parliament and of the Council of 19 may 2010, Official Journal of the European Union 2010 no. L 153, p. 13, and parts of Directive 2005/36/EC of the European Parliament and of the Council of 7 September 2005 on the recognition of professional qualifications in the EU, Official Journal of the European Union 2005 no. L 255, p. 22, as most recently amended by Commission Regulation (EU) no. 213/2011 of 3 March 2011, Official Journal of the European Union 2011 no. L 59, p. 4.

 

The existing BR10 sets the minimum energy requirements for all types of new buildings. These requirements relate to the energy frame and the envelope of the building. In addition to the minimum requirements, BR10 also sets the requirements for two voluntary low-energy classes: Low-energy Class 2015 and Building Class 2020. These two classes are expected to be introduced as the minimum requirements by 2015 and 2020, respectively. Building Class 2020 is defined in this Executive order no. 909.

 

The BR10 tightened the energy performance requirements for individual building components for all building types. This rule applies to the replacement or major renovation of the component. However, the measures must be economically feasible. This means that the annual savings multiplied by the expected lifetime of the measure divided by the investment should be higher than 1.33 or, put in another way, the measure must have a simple payback time of less than 75% of the expected lifetime of the measure. In case of full replacement of a component (e.g., a new roof, new window, new outer wall), the new component must meet the requirements set in the BR10, regardless of profitability.
