The recently updated Energy Performance of Buildings Directive (EPBD) is a pivotal legislative framework aimed at improving the energy efficiency of buildings across the European Union. While its primary focus remains on energy savings and decarbonization, the revised EPBD now formally recognizes the crucial link between energy performance and Indoor Environmental Quality (IEQ). This update requires member states to address IEQ in their national legislation, ensuring that energy-efficient buildings also support the health, comfort, and well-being of their occupants.
A Framework for IEQ, Not a Rigid Standard
A significant aspect of the updated EPBD is its approach to IEQ. Rather than imposing a single, rigid set of Europe-wide limit values for all IEQ parameters, the directive establishes a flexible framework. This approach acknowledges the vast diversity in climate zones, building types, and occupant needs across the EU. The consensus is that a one-size-fits-all model would be counterproductive, potentially leading to suboptimal outcomes and hindering innovation.
The new EPBD defines IEQ as a comprehensive concept that includes several key domains:
- Indoor Air Quality (IAQ): Addressing contaminants and ventilation.
- Thermal Comfort: Pertaining to temperature and humidity.
- Lighting: Considering both natural and artificial light.
- Acoustics: Controlling internal and external noise.
