Abstract (EN):
Portuguese school buildings are generally characterized by an in-service thermal
discomfort, due to the poor envelope thermal properties and the lack of resources for paying energy
consumption. Most Portuguese schools are free-running buildings with a natural ventilation strategy.
Hundreds of high and basic schools have not been refurbished and still have problems or anomalies
and inadequate in-service conditions and need to be rehabilitated in the near future. There will be,
therefore, an opportunity to apply the acquired knowledge of comfort, habits, energy consumption
and costs that have been studied since the last refurbishments (2008). This work studies the Portuguese
Brandão schools model (from the ’70s), including about 100 non-refurbished basic schools. A
prototype classroom was prepared in a Brandão school, in Porto. The in situ experimental campaign
consisted of temperature, relative humidity, CO2 concentration and energy consumption
measurements. The main tasks of this work are: (1) the validation of an advanced hygrothermal model
with experimental measurements before and after the prototype refurbishment; (2) development of a
sensitivity study in order to choose the best refurbishment and heating strategies for these buildings,
regarding their typology, the local climate features and the actual capacity to support the operating
costs; (3) assessment of the roof insulation thickness in Brandão schools; (4) quantification of
discomfort indicators.
