    Effect Of Urban Albedo Surfaces On Thermal Comfort
    (University of Eloued جامعة الوادي, 2017-05-01) Mansouri, O.; Bourbia, F.; Belarbi, R.
    Thermal comfort was and remains a major concern of the designers, makers, planners, climatologists and others, seeking at all costs to ensure the well-being, good health and comfort of citizens in both outdoor and indoor areas. They have addressed this issue in order to identify the main causes that generate the warming of urban areas and therefore contribute to the degradation of the exterior and interior thermal comfort of the inhabitants. It turns out that the reflectivity of materials known as the albedo, plays a leading role in this degradation. A numerical study was carried out to assess the thermal comfort of citizens by applying reflective materials for roofs, facades and floor. The results show that the reflective light paints help in moderating the microclimate, contrariwise, they participate in the degradation of thermal comfort.

    REALISATION AND EXPERIMENTATION OF A WIND TOWER FOR PASSIVE EVAPORATIVE COOLING IN HOT DRY AREA: HASSI MESSAOUD, ALGERIA
    (University of Eloued جامعة الوادي, 2018-01-01) Djouima, A.; Bouchahm, Y.; Bourbia, F.; Torkia, A.
    The wind tower is one of the solutions to overheating issues. Using them in Algeria would be a solution in cooling hot areas and reducing energy consumption and greenhouse gas emissions. This research aims to develop a passive alternative to active cooling by exploring potentials and design parameters of wind catchers. The configuration of this built tower was based on a modified version of a model by Bouchahm (2011). The methodology used to this end consists of experimentally exploring the efficiency of wind towers through direct heat transfer induced by humidification of its built columns. Experiments on cooling efficiency were performed. The temperature and relative air humidity were monitored from May to August 2007 with and without humidification of the tower columns. The results are comparable to those of the simulated model. Lower temperatures were also recorded.
