Toronto-based architecture firm DIALOG and engineers Buro Happold recently released a study meant to serve as one of the foundational climate action pieces from the City of Toronto’s City Planning Division.

The Thermal Comforts Study focused on several factors, including solar access, shade, the urban forest, wind, water, and cool materials. One of the key findings of the study was that July 15th was projected as the hottest day of the year.

Ensuring the quality and comfort of the city’s public spaces has gained heightened significance due to their role in serving and providing enjoyment to all city dwellers. As climate change intensifies extreme heat events, which are occurring more frequently, it is crucial to integrate thermal comfort considerations into the planning of the public realm. This approach is essential for building resilience in the city and adapting to changing climatic conditions.

The Study is based in part on a Thermal Comforts Survey, which identifies the seasons and specific times when people feel comfortable or uncomfortable, as well as their preferred outdoor spaces for leisure activities. The survey was initiated in July 2022 and received responses from 556 individuals over the course of 35 weeks.

Key findings include the need to address the requirements for maintaining a healthy tree canopy in urban areas. Specific conditions, such as sunlight, moisture, and healthy soil, are necessary for urban trees to thrive.
