5 December 2024, Webinar – Personalized Environmental Control System (PECS) in Action: Insights from Case Studies

Personal Environmental Control System (PECS) with the functions of heating, cooling, ventilation, lighting and acoustic has advantages of controlling the localized environment at occupant’s workstation by their preference instead of conditioning an entire room. This improves personal comfort, health and energy efficiency of the entire heating, ventilation, and air-conditioning (HVAC) system substantially. Personalized ventilation will also provide improved protection against cross contaminations, which are critical in open plan offices and workplaces with close distance.
