Policy Solution

Building massing

Mandate

Overview:

Summary: Varying heights among adjacent buildings can improve ventilation and provide shading. Buildings designed around a central courtyard can also create an internal shaded area.

Implementation: Include in design guidelines. Applicable to high-density downtown areas because adjusting building height and shape will maximize ventilation and allow heat and pollutants to dissipate

Considerations for Use: This is most applicable to new developments, but can also be used for redevelopment and infill in existing, highly dense areas.

  • Policy Levers: The mechanism municipalities can use to actualize the intervention. These policy levers will likely be used in combination with each other.

    MandateMandates are government regulations that require stakeholders to meet standards through building codes, ordinances, zoning policies, or other regulatory tools.
  • Trigger Points: Opportunities for municipalities to implement risk reduction and preparedness interventions based on the policy lever, building on the United Nations Environment Programme triggers used in the Beating the Heat handbook (2021).
