Potential of inertial ventilation for passive cooling in Brazilian climates

The objective of this study is to evaluate the potential of two inertial ventilation techniques (buried pipes and thermal phase-shifting) for passive cooling of buildings in Brazilian climates. Using EnergyPlus, a typical residential building was simulated in two locations (Sao Paulo and Florianopolis). Simulations consider 5 alternatives of passive cooling, combining different scenarios of controlled direct ventilation, buried pipes and thermal phase-shifting. Results show the potential of these techniques in freefloating as well as in air-conditioning mode.
