Sol OS
Josue Perez
Status: concept system with an interactive Sol Planner prototype and a Ruta Fresca mobile design exploration. Not deployed or validated by a municipality.
The Opportunity
Urban heat information exists across weather, climate, mapping, and public-data sources, but planners and residents make fundamentally different decisions with it. Sol OS explores whether one shared data layer can support two distinct products without forcing both audiences into the same interface.
This case study is based on desk research and design exploration. It does not claim completed interviews with municipal employees or residents.
One Data Layer, Two Products
Sol Planner — a desktop decision-support concept for planners comparing heat conditions, interventions, and confidence levels.
Ruta Fresca — a resident-facing mobile concept for finding cooler routes and nearby public resources.
Sol OS system overview
Sol Planner
Sol Planner Barcelona detail
The planner concept separates different types of evidence instead of presenting every value with the same certainty:
Measured
Estimated
Modeled
Illustrative scenario
These labels are an interaction-design proposal. They do not certify the accuracy of any underlying dataset or model.
Ruta Fresca
Ruta Fresca mobile experience
Ruta Fresca reduces the resident experience to one practical question: How do I reach my destination with less heat exposure today?
The current work explores cooler-route comparison, heat alerts, cooling resources, on-device location, and clearly labeled estimates. It remains a design hypothesis and has not been tested with residents.
Key Decisions
Split the products
A planner running simulations and a resident choosing a route do not share the same cognitive task. The concepts use a shared information foundation but separate product experiences.
Show uncertainty
Modeled or illustrative data should never look identical to direct measurements. Confidence labeling is part of the product interaction, not an afterthought.
No false precision
The interface should communicate what is known, estimated, modeled, or hypothetical before a user acts on it.
Proposed Validation
A credible next phase would require data-source review, accessibility testing, moderated sessions with intended users, and municipal or civic-technology partners. No deployment commitment should follow until those assumptions are tested.
Outcome
A product-system architecture, an interactive planner prototype, a mobile design exploration, and a clearly bounded validation path.
