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.
Our industry opinion on the Energy Performance of Buildings
What we expect from the revision of the Energy Performance of Buildings Directive
To be more effective, the following key points should be strengthened or included when revising the Directive:
- Increasing the renovation rate of European buildings
- Using the energy balance that considers both insulation AND solar heat gains to assess the thermal performance of transparent building elements like windows
- Recognising the benefits of daylight, natural ventilation and solar management to improve well-being and reduce energy consumption
- 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.
- Secure the complete declaration of all energy efficiency related performance characteristics of construction products.
