Abstract
This thesis investigates the night-time cooling performance of selected office rooms in the AAU BUILD facility during warm summer conditions. Using measured indoor temperature data obtained from the Building Management System (BMS), the study evaluates the influence of ventilation strategy, airflow conditions, thermal mass, and internal heat gains on overnight temperature reduction. The results reveal clear performance differences between ventilation types, with cross-ventilated rooms achieving faster cooling rates and greater overall temperature reductions than single-sided or non-ventilated rooms. Weekend periods are characterised by lower initial indoor temperatures due to reduced internal heat gains. Overall, the findings demonstrate the importance of effective airflow paths and thermal mass in mitigating overheating risk and improving indoor thermal conditions at the start of the occupied period.
