摘要：Portuguese school buildings are generally characterized by an in service thermal discomfort. The refurbishments that the schools have recently undergone, have not fully considered the climatic diversity and the economic reality of the country and, for that reason, there are still some discomfort in these schools. This work studies the PortugueseBrandãoschools model (from the 70’s), which comprises about 100 non-refurbished basic schools. A prototype classroom was prepared in aBrandãoschool, in Porto. The in situ experimental campaign consisted in temperature, relative humidity, CO2concentration and energy consumption measurements. With this prototype, some studies were carried out regarding the thermal behavior before and after a refurbishment process, by experimental monitoring. The prototype construction has included the improvement of the envelope (roof insulation and solar protection) and of the technical systems (ventilation and heating). The main goal was the assessment of the discomfort in this prototype before and after the refurbishment in free-running conditions or with some intermittent heating strategies. Discomfort indexes have been developed for the assessment of the discomfort. This work presents the prototype thermal performance in pre-existing in service conditions and the improvement in the thermal behavior of the environment after the refurbishment.
