ICLEI worked with Toronto Public Health to carry out research on strategies being used in other jurisdictions to manage extreme heat in older apartment buildings that don’t have air conditioning. The research included both a literature review and interviews with cities in North America and Europe. Eight key strategies were identified for managing extreme heat in Toronto apartment buildings, including active cooling, weatherization and insulation, increasing air circulation, reducing solar gain through windows, increasing natural ventilation, cooling/green/reflective external surfaces, minimizing internal heat generation and cooling on-site within the building.
