Importance of thermal stack effect in ventilative cooling concepts for residential buildings

This paper investigates the impact of ventilative cooling in residential buildings constructed from light-weight cross-laminated timber. Different temperature-controlled ventilative cooling concepts such as single sided ventilation, cross-ventilation and thermal stack based chimney ventilation concepts are simulated and compared in terms of impact on indoor temperature and robustness to external conditions such as the surroundings and the building orientation. Chimney ventilative cooling which makes use of the thermal stack effect has the largest impact on indoor temperature and is least affected by the external conditions.
