A Pre-Post Retrofit Evaluation on Indoor Air Quality and Comfort in Classrooms and Offices: Pre-Retrofit Findings

The BENEFIT project evaluates the indoor environmental quality in non-domestic buildings where energy efficiency upgrades will be implemented; a baseline for indoor air quality hass been established across 50+ environments prior to the commencement of retrofit activities. Initial findings in pre-retrofit environments reveal widespread underventilation and the significant influence of outdoor PM2.5 levels indoors in existing classroom and office environments. Detailed pre-retrofit results will be presented at an upcoming conference.
