Building Commissioning Operation and Environmental Impact

The report investigates overheating and CO₂ issues in the CREATE building’s atrium by analysing data from the Building Management System (BMS) and additional Eltek sensors. Measurements revealed a consistent vertical temperature gradient of about 2 °C between the ground and top floors, with the upper levels experiencing frequent overheating - up to 3 - 5 hours per day during occupancy.

 

Due to a fact of wrong sensor placement, natural ventilation of atrium wasn't properly working. A natural ventilation capability test showed that opening only the skylight windows could reduce atrium temperatures by approximately 1 °C per hour, proving significant untapped potential for passive cooling. The study identifies shortcomings in BMS sensor placement and window operation and proposes solutions such as adding top-floor sensors, utilizing façade windows, and improving system controls to enhance indoor comfort and energy efficiency.
