Optimisation et contrôle des flux d’air dans les bâtiments du CIMEC

In recent years, factors like thermal comfort, indoor air quality, and energy consumption in school buildings have received increasing attention. Lecture theatres and chemistry labs pose significant challenges for HVAC design due to thermal stratification in lecture theatres and ineffective ventilation in chemistry labs, caused by large spaces and pollutant generation, respectively. Despite many studies on these topics, there’s a lack of research on thermal stratification in cold climates like Quebec, where the issue is severe in winter, and on the effectiveness of local ventilation methods in chemistry labs.
To address these challenges, this project will conduct field tests and numerical simulations to analyze air distribution in an existing lecture theatre and a planned new chemistry lab in a Quebec college. The goal is to optimize indoor environment conditions and energy efficiency for both spaces. The outcomes will enhance thermal comfort, energy efficiency, and air quality, providing guidance for the design and control of air distribution, aiding renovations and new developments. This will help schools in Quebec and across Canada achieve healthier indoor environments, better thermal comfort, and greater energy efficiency.
