Abstract

In 2014, the Chilean Ministry of Housing and Urban Planning (MINVU) began to develop regulations for maximum levels of air infiltration in dwellings. This paper investigates the impacts of increased air-tightness on indoor air quality (IAQ) and energy use. The study uses computer simulations representative of social housing in Temuco, a city with heavy urban air pollution and cold winters. Results show infiltration measures produced reductions of -49% in air changes and -17% in heating loads. Emissions from six different types of wood, gas and paraffin burners including PM10, PM2.5, NO2, CO, SO2 and PAHs were modelled. changes of between -3% to +35% in individual contaminant concentrations, revealing that increased air-tightness does not necessarily imply a reduction in IAQ due to variations in deposition rates and reduced external pollutant ingress. As heater emissions exceeded pollutant concentration limits between 1-41% of the time, adopting cleaner heating technology is recommended
