Use of energy recovery ventilators to provide ventilation in schools and the impact on indoor air contaminants.

This study examines the use of energy recovery ventilators (ERV) in two schools located in a Southwestern arid climate as an energy-efficient means of providing acceptable ventilation to the classrooms and the corresponding effect on indoor air quality (IAQ) contaminant indicators. The effect of cleaning the existing systems· on thermal comfort conditions were also examined. IAQ measurements were made in selected classrooms with respect to carbon dioxide, viable and non-viable bioaerosols, volatile organic compounds, and respirable particles.

Tools for evaluating domestic ventilation systems (IEA Annex 27).

This paper is describing the preliminary results of the Annex 27 work aiming at developing simplified tools for evaluating domestic ventilation systems. In this paper is given the tool to evaluate a system's ability to deal with different indoor air quality (IAQ) matters. In the work is used sophisticated simulation programs studying pollutant concentration either for each person or in an individual room. The evaluation is to be applied on houses that mainly are heated. This means that the tools are restricted to the heating season.
