The client
Alteo Group and Aiset
Alteo Group is a Belgian consortium of 12 companies active in building energy: HVAC systems, cogeneration units, heat pumps, and industrial energy installations. Aiset, one of its subsidiaries, handles energy data monitoring and field operations across several European countries.
The group's engineers and project managers work daily with thousands of technical documents: equipment specifications, compliance certifications (BREEAM, PEB), installation reports, maintenance records, and client contracts, scattered across shared drives, mailboxes, and local folders.
Finding the right information at the right time was a constant bottleneck.
“Using the data stored on our servers is becoming essential for a technical consulting group like ours. With Colibri, we can bring this data to life in a secure and sourced way to increase our efficiency when writing proposals or consulting reports.”
Thomas Deville
Co-founder, Managing Director — Alteo Group
In practice
A real query, a real answer
Here is what it looks like when a project manager at Alteo asks Colibri a question about a building's certification requirements.
What happens here
A project manager asks: “What BREEAM certification level does this building target?”
Colibri searches the indexed document base and returns 5 source references from a technical specification document, with page numbers and relevance scores (0.86-0.89).
The answer states that the building targets BREEAM “Excellent” (score ≥ 70%), and that the project also targets a PEB B+ energy certificate, all sourced to specific pages.
The project manager clicks a reference and the original PDF opens at page 12, showing the exact section the answer was drawn from.
Agentic workflows
Beyond search: autonomous task execution
For complex tasks, Colibri activates specialized agents. At Alteo, this is how a Statement of Requirements gets generated:
The AISET Expert agent pulls structured building data, including equipment lists and energy metrics, from the Aiset database.
The Orchestrator cross-references this data with similar past projects found in the document base.
The Critic validates that compliance requirements are met and flags gaps.
The Responder assembles the final document using Alteo's own template.
The orchestration graph is fully customizable. Alteo can add new agents or modify the workflow as their needs evolve.
