Natural ventilation still one of the most basic elements of thermal comfort in the building to ensure cooling and air renewal of internal spaces, especially in the residential sector. With the concern for the unsustainability of fossil and non-renewable energies and the gradual rise of housing demand in Algeria, energy conservation has become a maj...

The French colonial architecture heritage in Algeria, in which the users did not use either heating, cooling active systems or artificial lighting, was classified as sustainable architecture before time. This old architecture nowadays needs to be rebuilt due to natural and men effects on it. Among these heritages, the secondary school in Miliana lo...

It is urgent to act currently on the problems of overconsumption of energy as well as the environment and the economy. Energy is a direct mechanical source of many devices of an artificial thermal environment of the modern habitat. To cope with the consequences of the exceed consumption of domestic use, architecture takes part by focusing on the ol...

The papers present a theoretical work on coupled passive cooling system, earth-to air heat exchange and high inertia well insulated solar chimney attached to the building south wall with direct outlet. The system was supposed to be used for summer cooling in hot arid zone in Ghardaia city in the south of Algeria. An investigation on the effects of...

The effect of wind velocity and night natural ventilation in lowering the inside daytime temperature in passive cooling in arid zones, were investigated by numerical calculations and experimental means for different rate of volume air change, 0.36volume per hour till 3.6 volume per hour for different wind speed. The numerical calculations based on...

Le présent travail, étudie et donne les possibilités, les limites, les conditions climatiques qui permettent d'optimiser les systèmes passifs de refroidissement. Une meilleure compréhension de 1'ensemble des contraintes et possibilités associés à un type de climat est nécessaire.

A full-scale evapo-reflective roof for arid climates has been developed. The proposed roof design is composed of a concrete ceiling over which lies a bed of rocks in a water pool. Over this bed is an air gap separated from the external environment by an aluminum plate. The upper surface of this plate is painted with a white titanium-based pigment t...

The microclimate and air quality in urban spaces are of a great interest for the well-being of citizens. Mitigating urban heat island is a major concern for human health by improving comfort especially in desert regions. While the thermal comfort is relatively easy to obtain in indoor spaces, it is more difficult to provide in outdoor ones. It is o...

An experimental study of passive cooling roof was carried out for a typical summer day of June for Laghouat in Algeria. The proposed roof design is composed of a metal plate ceiling over which lies a bed of rocks in a water pool. Over this bed is an air gap separated from the external environment by an aluminium plate. The upper surface of this pla...

A dynamic mathematical model used to predict the performance of passive cooling system by evapo-reflective roof in buildings for hot arid climates has been developed. The cooling system consists of a roof composed of concrete ceiling and flat aluminium plate, separated with air space partially filled with rocks and small quantity of water. Low emis...
