Abstract:
The paper explores mixed-mode cooling strategies in buildings with hybrid ventilation and high levels of exposed thermal mass and presents data collected over an extensive period of time using a full-scale experimental set-up in an occupied institutional building with motorized fa?ade openings integrated with an atrium. Night cooling strategies for thermal mass pre-cooling, with variable low temperature setpoint for control of airflow through operation of motorized grilles or a possible variable speed fan, are evaluated. Results for the thermal conditions in the highly-glazed atrium zone and the wind and buoyancy-driven airflow rates show that free cooling covers a significant portion of the building's cooling requirements while maintaining a comfortable indoor environment. The heat removal from concrete floor slabs is 2¨C5 times higher with the inlet air stream at an average temperature of 12 ˇăC, compared to that with an air stream at 15 ˇăC or 18 ˇăC respectively. These findings provide insights for space conditioning using hybrid ventilation that can support the development of model-predictive control strategies.
