“…Results previously presented are in line with other authors (Guedes et al 2009) and showed that, in terms of thermal comfort, the Portuguese climate allows the use in schools of ventilation systems with a strong natural component, combined with heating systems, such as hot water radiators, which should guarantee adequate temperatures during the winter season. However, some difficulties might be found related to the indoor air quality and, during summer, overheating could be a problem in some classrooms.…”

This chapter presents a methodology for the optimization of the insulation thickness of external walls and roofs. Its application in school buildings rehabilitation is tried. The methodology is presented and formulated. Objectives related to building's energy efficiency, summer comfort and life cycle cost are combined. A sensitivity analysis is presented and an example case is used to test the methodology.

“…According to the work of Dhaka et al [363] in India, there were a wide range of neutral temperatures (wider and higher than international standards) at 6 naturally ventilated student hostels. Based on the research of Guedes et al [364], who performed a field A c c e p t e d M a n u s c r i p t study in offices, homes for the elderly and educational buildings in Lisbon (Portugal), people experience the sensation of thermal comfort in wider temperature ranges than specified in ASHRAE 55 [364].…”

“…It should be noted that although several international studies support adaptive comfort methodologies, these are still not included in the large majority of the national regulations. (Corgnati et al 2009;Guedes et al 2009;Eusébio Z. E. Conceição et al 2012). …”

“…However, towards the goals of reducing energy consumption and considering the adaptive possibilities of students, our hypothesis is that in Portugal and in other southern European countries, natural ventilation in schools, both new and refurbished, has a great potential for successful implementation (Guedes et al 2009;Almeida and de Freitas 2014). Yet, according to the above mentioned, various examples have shown that the practical application of too rigid ventilation protocols not always proves efficient.…”

Abstract:Indoor environmental conditions in classrooms, in particular temperature and indoor air quality, influence students' health, attitude and performance. In recent years several studies regarding indoor environmental quality of classrooms were published and natural ventilation proved to have great potential, particularly in southern European climate. This research aimed to evaluate indoor environmental conditions in 8 schools and to assess their improvement potential by simple natural ventilation strategies. Temperature, relative humidity and carbon dioxide concentration were measured in 32 classrooms. Ventilation performance of the classrooms was deeply characterized, first by fan pressurization measurements of the air permeability and later by tracer gas measurements of the air change rate assuming different envelope conditions. A total of 110 tracer gas measurements were made and the results validated ventilation protocols that were tested afterward. The results of the ventilation protocol implementation were encouraging and, overall, a decrease on the CO2 concentration was observed without modifying the comfort conditions. validated ventilation protocols that were tested afterward. The results of the ventilation protocol implementation were encouraging and, overall, a decrease on the CO2 concentration was observed without modifying the comfort conditions.
