What Zenga Bvba does
Zenga Bvba is a privately held Belgian study and advisory bureau (consultancy) headquartered in Geel, Antwerp province, founded in 2006 at the inception of Flemish energy performance regulation. The firm delivers eight regulated professional services for construction projects: EPB (EnergiePrestatie en Binnenklimaat) reporting covering E-peil and S-peil calculations, safety coordination (veiligheidscoördinatie) on multi-contractor sites, EPC certificates for property transactions, blowerdoor and air tightness testing, ventilation pre-design and performance reporting (VVO/VPV), preliminary property condition reports, heat loss calculations under NBN EN 12831, and asbestos inventory inspections for pre-2001 buildings. Customers include architectural firms, contractors, real-estate developers, municipalities, healthcare operators, and private individuals requiring certificates for property sales or rentals. Operations are concentrated in the provinces of Antwerp, Limburg, and Flemish Brabant, and the firm operates as a single integrated team with two sister companies, GAB architecten (architecture) and Studiebureau Forté (structural and technical engineering), to deliver combined regulatory and building-process services on larger projects.
The business is structured as a bv (Belgian private limited company) with two named professional contacts, Yannick Van Gestel (Energiedeskundige) and Jan De Proft, and operates with no disclosed parent, institutional investors, or venture backing. The revenue model is fee-for-service professional consulting, with pricing tiers publicly disclosed only for asbestos inventory work (€225–€650 excl. VAT depending on building type and sample count); most other services are quote-based on request via the company website. Distribution is direct: customer acquisition relies on referrals from sister companies, an exclusive partnership with residential developer Woningbouw Verelst covering 100+ housing units per year since August 2016, and content marketing through a website blog covering Flemish energy regulation. Core technology consists of domain-specialised compliance software and standardised testing protocols (calibrated blowerdoor equipment, OVAM-aligned asbestos inspection procedures, STS-ventilatie reporting), with no software product offering, no API, no mobile app, and no AI or machine-learning capability disclosed in the source data.
The competitive position is anchored in regulatory licensing: EPB and asbestos services require certified energy experts and OVAM-recognised inspectors, and the firm has held bureau recognition since 2006, giving it a head start against newer entrants. Recent strategic activity includes expansion of the asbestos service line aligned with the Flemish government's 2040 asbestos-safe building mandate, and continued execution of the multi-decade Woningbouw Verelst exclusive partnership. The firm is actively operating with project case studies dated through February 2026, and maintains a job vacancy page indicating ongoing recruitment, but headcount, revenue, and customer concentration metrics are not publicly disclosed.

- Arcadis Belgium: Global design and consultancy firm with Belgian offices offering sustainability, energy and building compliance services that intersect with Zenga's Flemish regulatory offering, though at significantly larger scale.
- SGS Belgium: Global testing and certification firm providing asbestos, air tightness and energy performance verification in Belgium — overlapping with Zenga's inspection-led services as part of a much wider industrial testing portfolio.
- Vinçotte (KIWA): Belgium's largest inspection, testing and certification body; offers asbestos inventories, EPCs and building-related compliance services that overlap with Zenga's regulatory filings, though across a much wider industrial portfolio.
- Bureau Veritas Belgium: Global testing, inspection and certification group with Belgian operations in building compliance, asbestos and energy auditing — adjacent services to Zenga with greater scale and broader geographic reach.
- Sweco Belgium: European engineering consultancy with Belgian operations in sustainable buildings, energy performance and safety — adjacent to Zenga's EPB and safety coordination services but serving larger public and commercial clients.
- VK Engineering (VK architects+engineers): Belgian architectural and engineering group delivering integrated building design including EPB, ventilation and safety coordination across Belgium, competing with Zenga on larger projects via a bundled design+compliance offer.
Regional players
- Ingenium Group: Belgian engineering consultancy providing technical building studies, EPB reporting and HVAC design across Flanders — directly comparable technical services to Zenga but with a larger engineering and HVAC design focus.
Direct peers
- Certipro: Belgian energy performance certificate (EPC) issuer active in Flanders and Wallonia, delivering the same residential and small non-residential EPC filings that form one of Zenga's core services.
Others
- WTCB / CSTC (Belgian Building Research Institute): Flemish/Dutch-speaking building research institute that defines technical standards (STS-ventilatie, EPB methodology) underpinning Zenga's work. Not a direct competitor but a key ecosystem player whose standards shape Zenga's service specifications.
