Indoor Environment Quality - Casas de Santo António, Barreiro

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


In the context of a growing change in the way we inhabit and regarding the time spent indoors, the quality of indoor air and, more generally, all the factors related to the indoor environmental comfort such as air temperature, humidity and air movement, have become issues of major relevance. In this study we will analyze and pinpoint the relation between a set of physical factors that we present as contributing to the indoor environment quality, the bioclimatic and passive solar measures, together with other architectural solutions, and the quality of indoor environments; for that we referred to the case-study of urbanization of Casas de Santo António, which was developed in 2007 as a pioneering project for an econeighbourhood in Portugal. This way, we will begin by analyzing and systemizing which type of factors contribute in the process for obtaining indoor air quality and why; then we will analyze the case-study at the level of passive strategies, active and passive systems used to implement the project, such as the strategic importance of solar orientation of each volume housing, their places of permanence; and the relationship between them, given the emphasis attributed to exposure to direct sunlight in a continuous mode for all buildings. Therefore, we will also study a set of elements that have a direct impact on the quality of internal air, like the thermal insulation, the solar gains / losses, the natural ventilation, the ratio of glazed area in relation to its orientation and to the outside shade, materials and finishing, lighting, energy systems and solar thermal systems. It has also been considered interesting to assess the feedback from the residents of the urbanization, regarding their perception of indoor environment quality. In order to assess this relation, we will carry out a survey with residents designated A and B. This option is related to the belief that the quality of indoor environment, as well as thermal comfort levels, is largely influenced by users‟ behaviours.
