Development of normative calculation approaches for passive ventilative night cooling strategies - utilisation of brick storage masses

CoolBRICK addresses passive cooling strategies by using thermal brick storage masses. The main focus lies on the thermal discharge of brick walls through natural night ventilation, which is the only way to make these storage masses usable again during the day for reloading with solar heat. Through comprehensive monitoring of two completely identical brick simulation rooms located at the Bauakademie Salzburg, different control strategies for night ventilation as well as ventilation effects with different opening situations are evaluated "in situ" with identical climate and framework conditions. In addition, extensive thermodynamic simulations are carried out. Finally, the results will be used to calculate the cooling potential of these passive measures under different boundary conditions. This is to be included in the calculation basis of standards for the prevention of summer overheating (ÖNORM B 8110-3) as well as in a planning guideline.
