Lean Social Canvas
The Project's planning structure — animated by the DARE rhythm (Discover, Aspire, Refine, Empower).
Why (Opportunity)
City roofs get hot, shed rain fast and do little for the street below. Green roofs promise cooler buildings and less flooding, but a small company can't show what one would do on its own roof, so few get built. Nobody had clean, local numbers.
What (Solution)
Measure it. A sensor network on PartnerCo's roof compares a planted section with a bare one: surface heat, rain run-off, and the energy used on the floor below. The test: six months of clean data with no gaps, then a method any building owner can reuse.
How (Plan)
Built with the city's BrandedCircle and the University of Amsterdam's. PartnerCo gives the roof and funds the pilot through its match; the university lends the sensor kit and a research assistant; the city sets the measures it will accept for its roof subsidy. Mira's crew checks the sensors on the first Saturday of every month.
Stakeholders
Beneficiaries
Building owners and tenants on hot, flood-prone streets; the city's climate team; the neighbours who come to the roof days.
Partners
BC Gemeente Amsterdam, BC University of Amsterdam, PartnerCo's data team (four hours a week, pro bono), and Mira's crew of twelve colleagues and neighbours.
Funders
PartnerCo's employee-giving match, 38 colleague backers on the UP rails, and sensor kit on loan from the university.

Assumptions & tests
DAREVolunteers can keep the data free of gaps
ValidatedExperiment: Monthly roof days and a check rota for six months
Metric: Days with complete data
Result: 100% — six months, zero gaps
Owner: Mira L.
Timeline: Jan–Jul 2032
The planted section cools the roof measurably
ValidatedExperiment: Planted and bare sections on the same roof, read by the same sensors
Metric: Peak surface temperature difference
Result: 18 °C on the hottest days
Owner: Erin Smith
Timeline: Apr–Jul 2032
The city will accept the method for its roof subsidy
TestingExperiment: Method review with BC Gemeente Amsterdam's climate team
Metric: Measures accepted, of five
Result: 4 of 5 accepted so far
Owner: Femke d.V.
Timeline: Jul–Sep 2032
Other building owners can reuse the method without the crew
NextExperiment: Two outside roofs run the method from the written guide
Metric: Days with complete data in their first month
Result: Starts once the canvas is signed
Owner: Project team
Timeline: Oct–Dec 2032
NAVi insights

Guidance for this Project, from across the domain.
Winter cover
The north array goes unchecked over the Christmas holidays. Two data-volunteer seats are open on Opportunities.
Suggested mentor match
Ghent's roof team runs the method on a school roof and offers peer calls. MentorMatch intake opens Monday.
Relevant course
UP Academe · “Sensor data in the field” — the crew's own module, for the two new volunteers.
Stage C route
Once the canvas is signed, a roll-out across the district qualifies for UP BusinessBank's Type 2 lane.
