Performance of a sensor-based passive ventilation control system in a temperate climate

McGill, Grainne; Mohamed, Sara; Sharpe, Tim

Abstract

Concerns regarding bedroom ventilation and IAQ are well known, however addressing problems in practice remains a challenge – particularly in passively ventilated homes that rely on occupants to open windows effectively. Sensor-based control systems are available to optimise the indoor climate using an algorithm to automatically control ventilation. Whilst these have been integrated in mechanical ventilation systems for some time, their application in passive ventilation solutions remain limited and there is a lack of research on their effectiveness in practice. This paper presents an analysis of bedroom ventilation conditions and IAQ (CO2, temp, RH, PM2.5, PM10) in new-build semi-detached dwellings in Glasgow. A door-to-door survey was conducted, followed by detailed measurements in four case study dwellings. Baseline conditions were established, identifying concerns regarding high bedroom CO2 and PM2.5 levels. The data will be used identify whether installation of the control systems (in Jan/Feb 2024) result in improvements to the indoor climate.
