Technical tools
Our interactive tools help organise information and produce preliminary results. They do not replace the studies, validation and professional responsibility required for execution.
Every result shows its data, assumptions, method, version and limits.
No coefficient is used without being displayed.
No public report becomes execution design.
The engine and method pack remain identifiable.
All three journeys work without an account. Account saving requires an active Supabase connection.
Preliminary solar sizing based on your appliances and visible assumptions.
Professional review required before execution.
Use the toolData collection, aggregation of supplied loads and geometric calculations without execution design.
Professional review required before execution.
Use the toolCumulative traffic calculation and road data inventory, without pavement thicknesses.
Professional review required before execution.
Use the toolA structured basis for discussion, never permission to execute.
Only verified packs produce a result. A new formula creates a new version; the back office never edits mathematical code.
No coordinate is saved automatically. A local draft requires an action and never leaves the device.
When Supabase is enabled, each new calculation creates an immutable run and keeps its version in the owner’s account.
CORESOLAR, CORESTRUCT and COREROAD are the public names of the three web tools. Their historical technical identifiers remain unchanged.
No. They organise data and produce only explicitly classified preliminary results.
The calculation keeps the identifier, version, formulas and references of the method pack used.
No. Local drafts stay on this device and account projects are private through RLS when Supabase is enabled.
Yes. Each tool provides a readable HTML view through the browser print or save-to-PDF function.
Execution results require data, standards, licences and validation beyond a public preliminary study.
You can request a professional assessment by voluntarily sharing a secure calculation reference.
Prepare your data now, then have execution decisions reviewed.
