Impact of the building airtightness and natural driving forces on the operation of an exhaust ventilation system in social housing in Chile

Chile has 1,626 social housing complexes with a total of 350,880 dwellings. Several studies have demonstrated a low thermal performance and high air permeability of the envelope of social houses throughout the country, causing surface condensation on walls, high heat losses in winter and low levels of thermal comfort for their occupants. The presence of high levels of indoor pollutants and/or indoor humidity has also been observed, causing respiratory and cardiovascular diseases in the occupants.

Indoor air and environmental quality in social housing dwellings in Australia

This study aims to assess the indoor thermal and environmental quality of low-income households in New South Wales, Australia. It adds evidence-based findings on the performance of residential buildings and contributes to improving the indoor environmental quality of social housing. The research presented in this paper involved subjective and objective evaluation of indoor air and environmental quality.
