Abstract

The objective of this work is to evaluate the energy performance of an individual house having an attic type roof considering the Algerian climate. The adopted methodology consisted in developing a thermal model of an experimental house, called “solar house”, which is located in the city of Bou Ismail near Algiers within the site of the Solar Equipment Development Unit (UDES). This experimental house is a single floor house with an attic type roof. The developed numerical model was validated using experimental measurements of indoor air temperatures. The validated thermal model was then used to evaluate several variants of the configuration of this house by changing the nature of the envelope, the type of attic roof and the ventilation rate. Three variants of the attic have been considered: without thermal insulation, with thermal insulation at the floor of the attic and with thermal insulation at the roof of the attic. The energy behavior of the different studied configurations was compared with a reference case which corresponds to a housing with simple glazing, with no thermal insulation, with no attic, with masonry walls and a reinforced concrete flat roof. This reference case corresponds to the existing adopted configuration for the majority of the individual constructions in Algeria. Thermal simulations were conducted for cities representative of the three main climates prevailing in Algeria. The models’ findings demonstrated that, in all climates in Algeria, the attic, isolated or not, brings a cooling energy savings.
