Deplasse & Associates

What Deplasse & Associates does

Deplasse & Associates is a Belgian engineering and strategic consultancy founded in 1999, operating as part of the ALTEO Group with approximately 60 employees across offices in Brussels (headquarters), Havelange (Wallonia), and Luxembourg. The firm delivers technical and strategic services for buildings and infrastructure in the energy-transition domain, organized into four departments — Engineering, Energy, Project Management, and Strategic & Environmental Consulting (the last added in 2020). Core service lines include technical maintenance control, technical due diligence, HVAC commissioning and energy optimization, remote health and performance monitoring, technical audits, and Energy Performance Contracts (CPE/EPC) conforming to the IPMVP protocol. A specialized Urban Heat Network (RCU) practice — covering planning, design, feasibility studies, satellite mapping, and commissioning — accounts for over 20 references and 200+ MW of cumulative thermal capacity in Belgium.

The underlying technology stack combines BIM tools (AUTOCAD, REVIT), GTC building management integration, IPMVP-based measurement and verification, and proprietary statistical databases co-developed with technological partners to accelerate district heating feasibility work. Differentiated offerings include outcome-based Energy Performance Contracts where part of fees are tied to actually achieved savings (demonstrated at ACP Parc Schuman with -25% fuel and -70% electricity reductions), and a 25+ year operational track record across healthcare (St-Luc UCL, HIS Bracops), pharmaceuticals (GSK Wavre), hotels (Martin's, Dolce La Hulpe, Radisson SPA Palace), collective housing, cultural institutions, and public sector clients (City of Charleroi/Igretec, Régie des Bâtiments, TIBI).

The business model is professional services and outcome-based fees: project-mission engagements for technical due diligence, audits, and engineering studies, combined with long-term EPC/CPE contracts where revenue is partially contingent on measured performance. Go-to-market is direct B2B sales-led across Belgium with cross-border activity into France and Luxembourg, supported by referral pipelines through the ALTEO Group parent and the Evolve Alliance (alongside Ecores, Beeodiversity, and Urbike). Customer segmentation is vertical, with primary segments in Building Owners & Property Managers, Healthcare Facilities, Hotels & Hospitality, Office Buildings, Public Administrations, Infrastructure & Utilities, and Collective Housing. Pricing is not publicly disclosed and is quoted on a project-by-project basis.
