A city is only as heat-ready as its least connected service.
Heat compounds ordinary infrastructure weaknesses. A vulnerable resident may experience the same event as unsafe housing, an exposed commute, unreliable power and delayed care. These are usually managed by separate teams using separate data.
The report’s central recommendation is to treat heat readiness as a shared operating system. This means common thresholds, a neighbourhood evidence layer, named service owners and a public performance record.
of high-risk neighbourhood blocks in the linked research record were missed by citywide temperature thresholds alone.
Build the operating picture in layers.
Exposure
Surface and indoor temperature, night-time persistence and local shade.
Sensitivity
Health, age, occupation and housing conditions that amplify harm.
Access
Transport, cooling, healthcare, energy and trusted communication.
Response
Trigger ownership, field operations, escalation and recovery learning.
“A heat map becomes useful only when it changes a route, a shift, a building or a service decision.”
Connect time horizon to ownership.
Operate
Local thresholds, outreach lists, cooling routes and continuity checks.
Coordinate
Shared data definitions, service playbooks and performance review.
Invest
Housing retrofit, shade, power resilience and public-realm redesign.
Learn
Publish outcomes, update assumptions and retain operational memory.
Start with one shared decision.
The quickest route to coordination is not a new platform. It is a specific decision that several teams need to make together: which neighbourhoods require outreach tonight, which routes need adjustment, or which facilities need backup support.
- Days 1–15: nominate an executive owner and define the first shared decision.
- Days 16–35: create the minimum evidence layer and document source limits.
- Days 36–60: run a tabletop exercise across service owners.
- Days 61–90: operate during a live event and publish the after-action record.
Use the edition as a working system.
The complete download includes a heat-readiness canvas, source inventory, service-owner matrix, threshold worksheet, after-action template and public reporting guide.
