Klictet

What Klictet does

Klictet is a Netherlands-based integral advisory bureau (legal entity: Klictet Advies bv) founded on 1 April 2005 in Oisterwijk, Noord-Brabant, by Stefan Janssen and Willem-Jan van den Berk. The firm delivers four interconnected professional services — installation technology advisory, building physics and fire safety, sustainability advisory, and monitoring and exploitation — for new construction and renovation projects. Its client base is concentrated in the Dutch built environment, serving project developers (e.g., BPD Ontwikkeling), educational institutions, healthcare organizations (e.g., GGZ Oost Brabant, Thebe), municipalities (e.g., Gemeente Tilburg), and commercial real estate. Klictet also operates a closely affiliated sister company, Gydz, which provides post-occupancy building performance monitoring using IoT sensors and a cloud platform.

Methodologically, Klictet is built around BIM (Building Information Modeling) as the backbone of its work, augmented by parametric design, augmented-reality verification via Dalux, VR walkthroughs, materials passports embedded in the BIM model, and Trias Energetica-based energy optimization. The firm uses Dutch regulatory calculation tools (BENG, MPG, GPR-gebouw, WLC-GWP, NTA8800) and supports BREEAM and Paris Proof compliance. In 2025 the firm moved from a two-founder management team to a five-person matrix organization to deliver these disciplines in an integrated way.

Klictet is a privately held, bootstrapped professional services firm with no external funding and approximately 30-32 employees, operating across multiple Dutch provinces. The company monetizes via project-based consulting fees (revenue is not publicly disclosed), engages clients through direct consultative sales and free initial consultations, and in June 2026 joined the Newfora network of specialized advisory and engineering firms. Its positioning is rooted in domain expertise in the Dutch regulatory and sustainability landscape rather than in proprietary software or AI.

Core offering

Klictet is an integral advisory bureau providing engineering consulting services for technical building installations (HVAC, electrical, mechanical), building physics and fire safety design, sustainability advisory (energy efficiency, circularity, BREEAM, MPG, GPR-gebouw, Paris Proof), and post-occupancy monitoring of energy, indoor climate, acoustics, and installation performance. Services span new construction and renovation across education, healthcare, residential, commercial, and public-sector buildings in the Netherlands. Engineering work is delivered through BIM-based coordination, parametric design, augmented and virtual reality verification, and energy optimization following the Trias Energetica methodology.

Product overview

Klictet is an integral advisory bureau offering four interconnected service lines: Installation Advisory (installatieadvies), Building Physics & Fire Safety (bouwfysica & brandveiligheid), Sustainability Advisory (duurzaamheid), and Monitoring & Exploitation (monitoring & exploitatie). The firm also operates a sister company, Gydz, focused on building monitoring and sustainability advisory using IoT sensors and cloud-based platforms. BIM-based working (Building Information Modeling) is embedded across all disciplines as a core methodology, enabling virtual design, clash detection, and lifecycle analysis. The portfolio is delivered as professional consulting services for the built environment (education, healthcare, residential, and commercial sectors), not as a standalone software product.
