Methodology Proposal for the Evaluation of Environmental Quality in Inhabited Indoor Facilities from Measurements of Carbon Dioxide Concentration

The indoor air quality (IAQ) and thermal comfort in public and residential buildings is relevant when in operation. However, to date it is not regulated nor subject to control in Chile, despite the consequences of a poor IAQ due to high concentrations of CO2 on learning, concentration, productivity and health. At a first stage, the IAQ of 2 classrooms in the south of Chile (latitude 45°23’71’’S and 47°115’11’’S) was monitored and evaluated using the ASHRAE 62/2010 13,779UNE international standards, being finally contrasted with the results of occupant satisfaction polls. Starting from this point, a new methodology to rank campuses in a dynamic regime in accordance to indoor air quality is proposed, especially for those with a high density of occupation, which can be used to manage patterns of ventilation, to allow IAQ verification in a post-occupational regime, and to achieve a healthy environment adjusted to the space’s own profile.
