Summary: Exterior shading block solar exposure and can lower building temperatures and reduce the need for air conditioning. Examples include awnings or window attachments.
Implementation: Update building code to require exterior shading and adjust street projection requirements to increase the amount of sidewalk a shading structure may cover.
Considerations for Use: Shadings can be permanent or mobile depending on the climate and constraints.
- 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).
City planning processesIncludes city initiatives such as the development of climate action plan, pathway to zero-energy, master plan, transit plan, energy mapping etc.Introducing new or updated zoning/codesIncludes codes, zoning requirements or by-laws pertaining to urban planning and building construction activity.
