Assessing and improving ventilation system performance in Canadian multi-unit residential buildings

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.
