Description
Office users’ health, comfort and work productivity are influenced by the Indoor Environmental Quality (IEQ) of the environment in which they work. This study presents a three-months monitoring of the thermal, acoustic, visual and air quality conditions of two corporate open-plan offices, located at the ground and first floor of the building, through a commercial multi-sensor and the PROMET&O (PROactive Monitoring for indoor EnvironmenTal quality & cOmfort) system. It consists of a low-cost calibrated multi-sensor device that monitors the main parameters of IEQ domains, and a questionnaire used to collect feedback on occupants’ comfort. A designed user-friendly interface informs building managers and users about the objective and subjective data monitored. In each office ten PROMET&O multi-sensors, ten commercial sensors and ten tablets were positioned over the occupants’ desks. Results show that a good agreement between the objective conditions and the subjective perception is more evident in the thermal and acoustic domains. Carbon dioxide concentrations fall within the recommended values, but a low air quality perception in the ground floor office is evident. Horizontal illuminance values rarely are higher than 500 lx, with occupants more satisfied in the first floor office than in the ground floor one.
