A methodology for post-occupancy evaluation of ventilation rates in schools

The importance of maintaining adequate indoor air quality in schools is recognised as a contributing factor to pupils' learning performance. This paper describes a series of field measurements that investigating the ventilation rates in four recently built secondary schools in England. All schools were assessed for compliance with the recently adopted Building Bulletin 101, which defines the set of criteria in relation to the ventilation rates and indoor air quality in new school buildings. Using the obtained results a methodology has been suggested for post-occupancy evaluation of ventilation rates in schools. The suggested methodology draws particular attention to the dynamic nature of the interaction between the building and their occupants.Practical application: The new Building Bulletin 101 is quoted in Approved Document F as a means of compliance with Building Regulations for school buildings in the UK. This paper, based on four case studies, highlights some of the problems facing architects, mechanical engineers and building control officers associated with post-occupancy evaluation of ventilation rates in new school buildings. The methodology suggested in this paper, which differs radically from the current practice, takes into account the changing nature of the indoor environment in schools including occupancy level and occupant behaviour.
