Abstract

Ensuring accurate indoor environmental monitoring is essential to maintain healthy living conditions and to improve energy efficiency. The placement of environmental sensors plays an important role in the reliability of collected data, such as temperature, relative humidity, and carbon dioxide (CO₂) levels. While standards such as BS 40101:2022 provide recommendations for sensor placement, practical constraints often induce deviations, which may affect data accuracy. This paper assesses the impact of sensor positioning. Multiple Ei1025 sensors are placed on walls and ceilings within a residential setting. Variations in readings across different locations are analysed through statistical methods. The work identifies that an optimal placement of these sensors is important as stratification of indoor air, exhalation of occupants and circulation of air impacts the readings. As an output, the determination of correction factors based on detected deviations will be presented. These findings are expected to contribute towards enhancing the indoor environmental monitoring practices. This would eventually support the development of improved residential ventilation strategies as well as ensuring robust data collection for future building performance assessments.
