Background and Objective of IEA-EBC Annex 78. Supplementing Ventilation with Gas-phase Air Cleaning, Implementation and Energy Implications

The proposed Annex should bring researchers and industry together to investigate the possible energy benefits by using gas phase air cleaners (partial substitute for ventilation) and establish procedures for improving indoor air quality or reduced amount of ventilation by gas phase air cleaning. The project shall also establish a test method for air cleaners that considers the influence on the perceived air quality and substances in the indoor air.
