Night warming speed
0.0x
Nighttime warming outpaces daytime in urban systems.
Zhao et al. 2014
Climate Intelligence Platform
Climate change kills at night.Who gets to sleep cool is a justice question.
NightBreath reveals a hidden urban emergency: nighttime minimum temperatures are rising faster than daytime highs, and the first neighborhoods to lose safe sleep are overwhelmingly low-income, racialized, and historically marginalized.
The Invisible Crisis
Why nighttime heat is a public health emergency
Consecutive hot nights risk
0.0 nights
Organ system strain compounds rapidly after repeated non-recovery nights.
Mora et al. 2017
Heat mortality timing
Nocturnal
Most heat deaths occur overnight and in the early morning period.
Murage et al. 2017
Urban attribution
High
Urban form materially amplifies mortality in heat events.

Operational Accountability
How this becomes real in 90 days
NightBreath is designed to be judged on implementation evidence, not interface polish. These milestones, targets, and safeguards define what success means in a real municipal-community pilot.
Days 0-30
Baseline and Governance Setup
Create a neighborhood heat equity cell with municipal staff, community organizations, and resident advisors to validate local risk maps.
Deliverable: baseline heat-risk register + outreach protocol.
Days 31-60
Rapid Intervention Sprint
Run overnight check-ins, cooling-site wayfinding, and low-cost home cooling supports in highest-burden blocks identified by NHVI.
Deliverable: weekly operations dashboard + issue escalation log.
Days 61-90
Measure, Adjust, Scale
Compare pilot outcomes against baseline, tune intervention sequencing, and publish a policy-ready scale plan for the next season.
Deliverable: public pilot report + 12-month investment roadmap.
Pilot scorecard targets
Exposure Reduction
Pilot target: 0.6-1.2C modeled nighttime improvement in priority blocks.
Equity Allocation
Pilot target: >=70% of direct resources allocated to highest-NHVI quartile neighborhoods.
Response Operations
Pilot target: alert-to-outreach activation in under 45 minutes during extreme nights.
Community Co-Governance
Pilot target: at least 4 resident and Indigenous-informed co-design sessions each quarter.
Cooling Access
Pilot target: measurable increase in overnight cooling-site utilization in high-risk zones.
Evidence Transparency
Pilot target: every brief includes confidence bounds, data freshness, and assumptions.
Anti-Displacement Guardrail
Pair cooling upgrades with tenant-protection and anti-displacement policy triggers to prevent climate gentrification.
Two-Eyed Governance
Require interventions to pass both scientific validity checks and place-based knowledge review before deployment.
Trade-Off Disclosure
Report energy, biodiversity, and cost trade-offs alongside every recommendation to avoid single-metric optimization.
Implementation Readiness
Built for deployment, governance, and public communication
Execution speed
Rapid demo-ready architecture
Single URL with live pulse, map, dashboard, and toolkit. Fast to explain under time pressure.
Decision support
Supports executive brief + narrative flow
PDF brief export, visual evidence layers, and phased implementation story are built-in.
Systems alignment
Covers all 4 themes + 4 lenses
Adaptation, collective action, climate tech, and systems outcomes with equity-first Two-Eyed Seeing.
Our Approach
Four design lenses for climate operations
Equity and Justice
Night heat maps onto racial and economic segregation. We prioritize interventions where NHVI is highest and frame cool sleep as a right, not a luxury.
Practicality
Action starts this week with mutual aid and cool-sleep protocols, then scales to roofs, trees, and infrastructure pilots that can launch with low-cost sensor kits.
Two-Eyed Seeing
Persian badgir, courtyard cooling, stepwell refuge design, and Aboriginal thermal landscape reading are treated as advanced engineering knowledge alongside climate science.
Systems Thinking
Night cooling intersects public health, housing justice, urban forestry, energy poverty, biodiversity, infrastructure, and policy. We model interventions as linked system levers.
About
NightBreath
Built for municipalities, nonprofits, and response coalitions that need neighborhood-level heat intelligence and clear implementation pathways.
This platform combines Toronto-aligned mock structures with live public data integrations and evidence-grounded methods to support rapid piloting through a single operational interface.
