Impact of the Thermal Inertia of Material on the Hygrothermal Comfort of Building

International audienceThe thermal inertia of buildings, topic of our subject is behind the intelligent relation that rests in on the good thermal exchange understanding between the inside and the outside. She participates in the good output, to the good use and the comfort of the thermal machine (building). An investigating has been led on a house of the colonial time in Guelma town (Algeria), in order to estimate the role of the inertia on hygrothermal comfort. Results show that the use of a local material adapted to the region climate is to the origin of the realization of hygrothermal comfort and the consumption reduced of the energy. The validation of results of the investigating by the software computer TRNSYS reaffirms the major role of the thermal inertia in the maintenance of the hygrothermal interior balance. Although, the thermal inertia of materials, according to results, must be associated to the means of heating and natural cooling (nocturnal ventilation) for the most unfavorable situation
