Strengthening Indoor Environment Quality (IEQ) in the revised Energy Performance of Buildings Directive
Buildings account for approximately 40% of the EU’s overall energy consumption and for 36% of the EU’s overall emissions of greenhouse gas. 70% of the buildings that we will occupy in 2050 are already built. Our organisations therefore support the objectives laid down in the Energy Performance of Buildings Directive (EPBD), which aims to reduce the energy consumption of buildings.
However, as buildings are getting tighter and better insulated in order to reduce uncontrolled energy losses and increase their envelope performance, the air exchange by infiltration goes down to zero. Such lack of a dedicated ventilation system may deteriorate the Indoor Environment Quality (IEQ) with adverse effects on health, productivity and comfort.
Despite significant scientific evidence on the health benefits of improved IEQ in residential and non-residential buildings, the EPBD has so far been implemented without enough consideration to Indoor Environment Quality (IEQ), which encompasses indoor air quality, thermal comfort, lighting and acoustic environment. Solutions are readily available and encompass source control, dedicated mechanical ventilation technology, adequate filtration of incoming air as well as room temperature, humidity, CO2 level, and lighting controls.
The industry considers it as essential to promote systems and solutions that result in both high quality indoor environment and low energy consumption in new and existing buildings and consequently calls for action in order to strengthen IEQ aspects in future recasts of the EPBD by focusing on the following three areas:
- Better enforcement & refurbishment - Creating regulatory conditions to ensure better IEQ.
- Regular inspections and continuous commissioning of technical building systems to maintain the envisaged IEQ parameters.
- Use of demand control options.
Call to Action
We would therefore call on the European Commission to consider the following points when working on the EPBD or any related energy legislation:
- Ensuring better enforcement & refurbishment in the frame of the revised EPBD to create regulatory conditions to ensure better IEQ.
- Ensuring regular inspections and continuous commissioning of technical building systems to maintain the envisaged IEQ parameters.
- Including references related to IEQ in adequate legislation such as the revised EPBD.
- Raising opinion makers and public awareness on the benefits of an increased IEQ.
