Current standards for indoor air quality (IAQ) in non-residential buildings demand high air
renewal rates with different filtration stages and constant flow. Currently, new school buildings must
incorporate mechanical ventilation systems which modify traditional heating installations in order to
comply with the requirements for indoor air quality and energy efficiency. This study analyses the
technical and energy outcomes involved in a school building when changing from a traditional
central heating system with radiators, to an HV system which fulfils the current regulatory
framework
