SHORT TERM HEALTH IMPACT ASSSESSMENT OF INDOOR AIR QUALITY IN A MADRID OFFICE

The present study is a short term health impact assessment of indoor pollution. To know the indoor pollution is necessary to get information about outdoor pollution and meteorological conditions. In this work, the outdoor data coming from a mesoscale meteorological and air quality simulation with WRF/Chem. Effects on health of different ventilation modes and indoor emission scenarios have been analyzed for the NO2 and PM2.5 pollutants. A general office building located in Madrid has been simulated with the EnergyPlus model during full year 2016. The energy model includes the Generic Contaminant Model so the simulation system is an integrated framework for indoor pollution and energy demand. Results show that when the emitting sources are active, ventilation through windows improves health and if there are no active sources, the health of the building occupants is slightly deteriorated by the outdoor pollution. Ventilation during all year increases the demand of gas for heating four times. The health impacts of emitting sources are highest in the warm months due to the operation of the air conditioning system. The health impact of indoor emission sources is higher than the outdoor pollution. People in the zone where the emitting sources are located would experience a mortality and morbidity of 2.5 times more than in the non-emitting zones.
