Heat-risk civic intelligence

London is not cool anymore.

A public map that turns London heat vulnerability, 15-minute access and Infrared UTCI simulations into a story people can inspect, share and act on.

The product story

From record heat to street-level decisions.

01

Map unequal exposure

Start with the GLA and Arup Heat Vulnerability Index, then reveal where high exposure, sensitivity and lower adaptive capacity meet.

02

Drag the minutes lens

Move the pedshed and watch the area of concern change in minutes, not abstract buffers, so the map reads like a lived journey.

03

Use the May heatwave

The real May 2026 event becomes a design day for comparing how access, morphology and vulnerability respond under stress.

04

Simulate interventions

Run Infrared UTCI physics, compare design options and explain the block in plain English for planning, design and public review.
