Innovative EPC Indicator


Adequate levels of indoor air quality (IAQ), thermal comfort, lighting and acoustics in buildings are among the most important benefits and drivers especially for renovation, as they lead to improved health and comfort of the occupants. However, they are not currently covered by EPCs: this indicator will allow to assess the levels of comfort in terms of Indoor Environmental Quality for a given building through reliable and evidence-based inputs.

X-tendo will develop a three-section assessment approach, that will be tested in buildings, and will consist of a simplified checklist of installed systems and materials, indoor measurements of temperature, relative humidity and CO2-concentrations and a survey of occupants’ perception on aspects such as thermal comfort and indoor air quality.
