Misko ingénieurs-conseils

What Misko ingénieurs-conseils does

Misko is a private Belgian engineering consultancy founded in 2012 by François Doridant, operating across Wallonia (Belgium) and the Grand Duchy of Luxembourg through three wholly-owned entities: Misko Ingénieurs-Conseils SRL (Belgium, energy and special techniques), Misko Energy Sàrl (Luxembourg, energy), and Misko Concept Sàrl (Luxembourg, special techniques). The firm provides regulatory-grade energy performance services (PEB/CPE certification, energy audits and advisory, passive building design using PHPP, blower door testing combined with infrared thermography) alongside engineering studies for HVAC, plumbing, electricity, and smoke extraction. Technology is centered on physics- and regulation-based simulation and diagnostic instruments rather than software platforms. Service delivery is direct, with no resellers or intermediaries.

The firm holds the mandatory accreditations required to issue legally valid energy performance certificates in both jurisdictions, including the responsable PEB agrément, Klima-Agence Certified label, myEnergy agrément, and the Made in Luxembourg label held by Misko Energy since 2016 and Misko Concept since 2022. The customer base spans residential property owners (DTC for certificates tied to sales and rentals), public administrations (public procurement RFPs for schools, administrative buildings, sports halls), real estate developers, and architects and project managers engaging Misko as a subcontracted specialist.

Misko operates a fee-for-service, mission-based revenue model with project-scoped pricing and time-and-materials (régie) billing for out-of-scope work. Pricing is quote-based and not publicly disclosed. Since founding, the firm has completed more than 500 construction projects, manages 250+ active projects, and issues approximately 500 PEB/CPE certificates annually. Headcount has grown from 10 (2020) to 25 (early 2025), and the firm operates four offices (Bastogne, Beaufays, Bertrange, Nothum). Ownership remains founder- and partner-held with no external investment identified.
