TESSA 6.0 is our biggest release yet: bring your own buildings and streets, optimise what you connect and how you route it, and see the financial consequences live.
Highlights
- Custom project building & street datasets: Import your own building footprints and road graphs via OpenStreetMap or custom GIS uploads, enabling project design anywhere in the world alongside official Swiss registers (RegBL, swisstopo).
- Individual building demand curves: Upload measured 8760-hour meter readings for individual buildings. Real metered consumption is blended with simulated archetype demand across the rest of the district for unmatched accuracy.
- Substation & connection investment modeling: Automatically compute detailed capital expenditures for service connections and building substations (fixed and capacity-dependent CapEx), feeding directly into financial cash flows.
- Rebuilt Financial Analysis workspace: Multi-tab financial reports with live KPI updates, customizable Capex/Opex line items, and interactive toggles to include or exclude specific investment components.
- AI-driven building selection optimizer: Algorithmic selection using prize-collecting Steiner tree optimization on road graphs to identify the most financially attractive buildings to connect.
- Street-aware layout optimization: Automated network routing that searches branching street-following topologies to deliver minimal pipe lengths and excavation costs.
- Physics-based pipe heat loss simulation: Temperature-dependent thermal loss simulation for buried pre-insulated pipes (EN 253 series 1/2/3, high-performance PIR, and uninsulated anergy lines), replacing fixed-percentage approximations.
- Scenario activity timeline: Comprehensive audit log displaying who created, modified, simulated, or duplicated scenario variants.
- Live GIS synchronization: Dynamic KML/KMZ network links allowing GIS software (such as QGIS and Google Earth) to automatically refresh map layers as designs evolve in TESSA.
