TESSA 6.1 sharpens the geothermal and financial toolkits, makes it easy to spin up scenario variants from filtered building sets, and takes demand modeling beyond Switzerland.
Highlights
- Dedicated borehole ground regeneration modeling: Ground regeneration is modeled as an independent thermal resource with dedicated annual supply curves and explicit tracking on Sankey diagrams.
- Target IRR tariff solver: Automatically back-calculate the required heat selling price (€/MWh or CHF/MWh) needed to hit an organization's target Internal Rate of Return (IRR).
- Separated Capex and O&M financial boundaries: Clear cost categorization between central production plants, distribution network piping, booster heat pumps, and customer substations.
- Advanced district & building filtering: Powerful spatial and attribute filters allowing planners to isolate building subsets and spawn new scenario variants in one step.
- High-availability platform updates: System upgrades deploy seamlessly in the background, ensuring continuous access during active planning sessions.
This release also includes the following improvements since version 6.0
v6.1.3
- Organization license & seat management: Streamlined administration for fixed and floating team licenses, with clear visibility into available datasets and user allocation.
- Automated borehole drilling permit checks: Quickly evaluate local drilling suitability, regulatory constraints, and permit prerequisites directly from the borehole field inspector.
- Configurable booster heat pump billing boundaries: Define whether thermal energy delivery is accounted for before or after building booster heat pumps in ambient networks.
- Refined energy & financial metrics: Delivered thermal energy accounting strictly reflects metered energy supplied to buildings, paired with updated regional tariff benchmarks for realistic feasibility evaluations.
v6.1.4 & v6.1.5
- Cooling-only load curve upload: Upload dedicated 8760-hour cooling load profiles for districts or individual buildings, ensuring accurate sizing for cooling-dominated and seasonal systems.
- International building demand models: Expanded archetypes incorporating European building stock datasets (including the UK via TABULA), enabling rapid demand modeling outside Switzerland.
- Dedicated Project Manager role: Team members can create, organize, and manage project scenarios without requiring full organization-level administrator privileges.
- Cross-project scenario comparison: Compare design variants across different organizational projects with unified permission checks.
v6.1.6
- EnergyPlus Weather (.epw) climate file upload: Upload custom local climate files directly in the standard EnergyPlus Weather format, complementing existing tabular inputs. Weather station metadata and observation periods are detected automatically.
- Interactive feature & building property editor: View and edit custom attributes and user-imported data fields directly within the map layer inspector, providing full control over building-specific parameters.
- On-map pipe diameter labels: Display nominal pipe diameters (DN) directly on the map alongside building labels to immediately inspect network sizing results.
- Enhanced GIS geometry import: Seamlessly import network geometry containing multi-part lines and elevation data from external GIS tools without manual pre-processing.
v6.1.7 to v6.1.10
- Create buildings from a layer: Build a buildings table from an existing layer instead of an upload.
- Remap layer properties: Rename a layer's free-form properties with a new tool.
- Fixes: The building properties editor accepts input again, the phasing plan no longer crashes when cash flow is not set, and editing a scenario no longer requires project-edit rights.
