The aluminium industry supports the holistic optimisation of the energy performance of buildings taking into account outdoor climatic and local conditions, as well as indoor climate requirements and cost-effectiveness, as required by the Energy Performance of Buildings Directive. Since its recast in 2010, the Directive has contributed to improving the performance of European buildings, but renovation rates are still too low, and we are facing inappropriate setting of minimum performance requirements for some building elements, too much focused on thermal insulation and neglecting other thermal characteristics. A proposal to amend the Energy Performance of Building Directive, was part of the ‘Clean Energy for all Europeans’ package presented by the European Commission in November 2016.
Our industry opinion on the Energy Performance of Buildings
What we expect from the revision of the Energy Performance of Buildings Directive
On top of being supportive of any measure susceptible to unlock the renovation of the EU building stock, the following key points should be strengthened or included through the revision process:
- Enforcing the definition of “Nearly Zero Energy Buildings”, reminding that minimizing operational energy needs comes as first priority, as defined in the Energy Union Strategy.
- Using the energy balance that considers both insulation AND solar heat gains to assess the thermal performance of transparent building elements like windows
- Improve maintenance of active control systems and their controlled elements
- Secure the complete declaration of all energy efficiency related performance characteristics of construction products.
- Recognising the benefits of daylight, natural ventilation and solar management to improve well-being and reduce energy consumption.
