Cost-optimality in building renovations
Discussing methodology and challenges within the recast Energy Performance of Buildings Directive.
This publication supports the EU comitology process on cost-optimality in building renovations that started following the EPBD recast (Directive 2010/31/EU). It is targeted at all internal and external stakeholders of this process and explains the background, process and generic principles of the methodology.
The issue of cost-optimality is a key within the EPBD recast. It goes deeply together with how far regulations can require property owners to undertake renovations after, for instance, a building performance certificate has been issued with recommendations. The EPBD recast requests that Member States shall ensure that minimum energy performance requirements for buildings are set “with a view to achieving cost-optimal levels”. The cost optimum level shall be calculated in accordance with a comparative methodology. The following text summarises the provisions of the EPBD regarding this approach.
