Building: Simon Fraser University, Departments of Mathematics and Statistics, Burnaby
Goal – The goal of this project is to analyze the effectiveness of dynamic, electrochromic, glazing in maintaining thermal comfort in the south facing offices during five months of the year (May 1st to September 30th) without relying on mechanical cooling.
Monitored office operative temperatures from May to September of 2017 before window replacement
Old windows – Simulated operative temperatures for north-facing windows (left), and south-facing windows (right), adaptive operative temperature limits, monitored ambient temperature, and exceedance hours
Dynamic glazing windows – Simulated operative temperatures for south-facing windows, adaptive operative temperature limits, monitored ambient temperature, and exceedance hours
Methods:
- Real-time and historic systems and environmental data from the building management system
- Additional environmental data collected
- Airflow testing: pressure and flow
- Dynamic building simulation model, calibrated with real data
- Coupled airflow model, calibrated with real data
- Pending: occupants’ thermal comfort questionnaires & interactions with dynamic windows
