What J. van Toorenburg does

J. van Toorenburg B.V. is a Dutch family-owned industrial engineering consultancy founded in 1979 by Jan van Toorenburg and headquartered in Rijswijk, Netherlands. The firm specializes in advisory services for heating, cooling, and electrical (HVAC/E) installations within construction projects, acting as an independent installation advisor and technical consultant that bridges the gap between construction and installation disciplines. The company serves seven core verticals: offices, schools/education, healthcare/care institutions, residential, infrastructure, retail, and building transformations. Named clients include Dura Vermeer, Colliers International (18+ year partnership), Gemeente Den Haag, Erasmus Universiteit Rotterdam, Royal Boskalis Westminster, and Decathlon. The firm has approximately 22 employees, of whom 7 are members of the Van Toorenburg family, and is currently transitioning into its third generation of family leadership.

The company's core service offering is Installation Consulting (Installatieadvies), delivered alongside BIM (Building Information Modeling) methodology that supports collaborative design, clash detection, and lifecycle analysis with project partners. A notable proprietary offering is the Installatieconcept Care Concept (ICC), co-developed with ClimaRad, which delivers decentralized CO2-based ventilation, heating, and cooling for flexible healthcare and multi-functional buildings. The firm is ISO 9001 certified for its internal quality management system and operates primarily through tender-based acquisition, with sustainability and innovation as key differentiators in bids.

Commercially, J. van Toorenburg operates as a sales-led professional services firm with revenue generated through custom, project-based fees. Pricing is not publicly disclosed; each engagement is quoted based on scope and complexity, and contracts typically span multiple years. The company executes more than 150 projects per year, including 10-15 school renovation projects annually, and serves both enterprise customers (e.g., Dura Vermeer, Royal Boskalis Westminster, Decathlon) and government clients (e.g., Gemeente Den Haag). Business development relies heavily on referrals and long-term client relationships, complemented by a content marketing presence via its website, blog, LinkedIn, and earned media (a feature on RTLZ's 'Nederland Maakt Het'). The firm has no external investors or parent company, operates primarily in the Netherlands with limited activity in Belgium, and reports no public revenue figures.
