01 · Geodata

How compact is a building, is the ground suitable for borehole heat exchangers, and what would it cost to rebuild? Three questions, one map.

The approach: Automatic calculation of characteristic length, suitability for a borehole field and reinstatement value from building footprints, height and subsurface data.
The technology: Web app with a Python pipeline. Starting in Vienna, expanding to all of Austria with LoD1 models and BEV laser scan data.
The benefit: A consistent first overview for refurbishment, geothermal energy and valuation, without manual work per property.

02 · Market model

What happens to rents, prices and new construction when implementing the EPBD makes building more expensive?

The approach: A dynamic, segmented model after DiPasquale and Wheaton – change the assumptions, see the effects immediately.
The technology: Interactive web tool. External validation and presentation at WIFO in preparation.
The benefit: Scenarios for banks, owners and policymakers – played through transparently instead of merely debated.

03 · Expansion

Where should a fast-casual concept open first in Vienna – and in which order should the next sites follow?

The approach: A weighted scoring matrix for five candidates, producing a staggered opening sequence.
The technology: AI-assisted assessment tool with GDPR documentation and a ten-year model for earnings and cash flow.
The benefit: A traceable expansion decision instead of gut feeling, transferable to any multi-site concept.

04 · Valuation

How quickly can a valuer build their own tool according to the European Valuation Standards – without a development team?

The approach: Live build with Claude at the TEGoVA conference on 23 October 2026: from the standard to a working prototype.
The technology: Vibe coding: requirements in natural language, the AI writes the code, the expert reviews it.
The benefit: Tools that fit your own practice exactly – instead of a practice that fits the standard software.

We build the tools we need ourselves.
