Evaluating the IAQ of Low-Energy Residential Buildings

Subtask 1 aims at defining the metrics to enable a proper consideration of both energy and IAQ benefit in building design and operation. A first step consists in determining a list of target pollutants commonly found in residential buildings by identifying pollutants that are listed as harmful. Existing IAQ metrics will be reviewed to propose the best scientifically-sounded index (or set of indices) for the evaluation of indoor air pollution. The IAQ indices consider different pollutants, exposure limits and aggregations. A last part of the subtask will be dedicated to the inclusion of energy in the proposed evaluation.
