- Kindergartens and nurseries in central portugal. assessments of indoor environment qualityPublication . Pinto, Manuel; Lanzinha, João; Viegas, João; Infante, Ana; Freire, TiagoThe Indoor Environment Quality study takes on a very significant challenge when analyzed, mainly, in buildings that encompass a more sensitive and susceptible type of population, as is the case of children. To comply with a set of requirements, namely the concentration of pollutants and the conditions of hygrothermal comfort, is a necessary condition to keep an interior environment suitable for the permanence of the occupants. A research project, that studied Indoor Environment Quality in four buildings which hold nurseries and kindergartens, was carried out in two cities in central Portugal, Viseu and Covilhã. The following main conclusions may be drawn: most compartments are not comfortable in terms of ambient temperature, but the relative humidity has reasonable values. Air change rates generally have low values and the measured pollutants have worrying values. Based on the observed problems and reached conclusions, some recommendations are proposed.
- Quality of the Indoor Environment in Elderly Care Centers in Two Cities in Central Portugal: Viseu and CovilhãPublication . Pinto, Manuel; Lanzinha, João; Viegas, João; Infante, Catarina; Freire, TiagoAssessments of Indoor Environment Quality (IEQ) present a very significant challenge when analyses are undertaken mainly in buildings that include a particularly sensitive and vulnerable population, such as elderly people. In order to maintain an indoor environment that is adequate for occupants, it is necessary to comply with a set of requirements (for TVOC, the Portuguese threshold values) regarding concentrations of airborne pollutants and hygrothermal comfort conditions. This paper studies IEQ in compartments in 3 buildings in two cities in central Portugal, Viseu and Covilhã, which hold elderly care centers. The following environmental parameters were continuously recorded: air temperature, relative humidity, concentration of carbon dioxide, formaldehyde, and total volatile organic compounds and ventilation rates. An analysis of the obtained results was performed, taking recommended guidelines and threshold values into account, thus making it possible to evaluate the IEQ conditions and hygrothermal comfort in the selected indoor spaces. On the basis of the conclusions reached and the observed problems of hygrothermal comfort and indoor pollutants in the indoor spaces, a number of recommendations are proposed, specifically in terms of climate control, ventilation, and maintenance, in order to obtain an overall improvement of IEQ.
