Assessing and improving ventilation system performance in Canadian multi-unit residential buildings
Assess performance of the centralized pressurized corridor ventilation system vs. decentralized ERV system in two architecturally similar side-by-side high-rise MURBs in Toronto and investigate methods to improve performance through coupled energy and airflow simulations.
The project aims to develop predictive controls to optimize fan coil control and window shading control using model-based and model-free computational strategies with the objective of improving energy efficiency and occupant comfort, including thermal comfort and visual comfort.
Improving Residential Indoor Environmental Quality to Promote Aging in Place
This project uses surveys, interviews, and field measurements to characterize the indoor environmental conditions (including light, thermal, acoustic and air-quality) in seniors’ homes, to provide targets for improvement.
Developing an Automated Tool for Evaluating Building Thermal Resilience
Create automated tool to translate building performance model into thermal resilience model.
