Interest of Thermal Mass Activation in the Case of Natural Ventilation
Thermal mass activation (TMA) can assure,in certain cases,thermal comfort conditions without the need of air conditioning systems.Even if other cooling systems have to be used,night ventilation significantly reduces the duration of the working time of additional cooling systems.The desired night ventilation rate (NVR),could be achieved using either mechanical ventilation,natural ventilation or a combination of these two methods (hybrid ventilation system).In this paper,we will investigate the feasibility of night cooling using natural ventilation for a residential building in a hot region of France:Carg(e)se.We will develop a model that calculates the internal temperature according to the heat balance and the combined effects of buoyancy and wind forces.Besides,we will study the effect of the internal finishing on the effectiveness of TMA.What type should we choose? And if we decide to use a suspended ceiling,a raised floor or a gypsum board in front of a concrete wall,what impact will this choice have on summer comfort?
