Ventilation System Improvements

System Testing Identifies Inefficiencies

63,630 CFM; 100 HP

Test results highlight airflow and static pressure anomalies for correction by the project engineers

Targets Drive Continuous Improvement Guided by current best practice among Greening Health Care hospitals, SickKids is working towards energy targets below 40 ekWh/ sf for our two main sites, and below 50 ekWh/sf for McMaster
