DENDRIT

What DENDRIT does

Dendrit Haustechnik-Software GmbH is a German software vendor headquartered in Dülmen that builds specialized calculation and planning tools for building services engineers, with a focus on sanitary and heating installations. Founded in 1988, the company serves a German-language customer base of more than 21,000 users working in Haustechnik planning. Its commercial activities center on two core products: CALHYDRA, which links precision sanitary and heating calculations directly with BIM software for continuous integrated planning, and STUDIO (with DendCAD), a standalone CAD solution for graphical planning and calculation of sanitary and heating trades in a single system.

The platform is organized around modular calculation functions including drinking water installation calculation and simulation, drinking water heating, building and property drainage, heat load calculation, and heating pipe network calculation. Output modules generate material extraction lists, hydraulic reports, and analyses, supporting planning documentation. A complementary service, Product Data on Demand (pdod.de), provides centralized manufacturer product data integrated into the BIM process from planning to operation. The underlying architecture combines BIM interoperability, CAD-based planning, regulatory compliance validation, and project management.

Dendrit operates a direct, sales-led go-to-market targeting building services engineers and planners via its website contact channel and a practitioner-led seminar program, with personalized engineer-to-engineer support. Revenue is generated through software licenses and subscriptions for CALHYDRA and STUDIO products; pricing is not publicly disclosed and is negotiated through contact-based sales. The company is a privately held German GmbH with no disclosed parent company, no external funding, and no recorded M&A activity in the available data.

Core offering

Dendrit develops and sells specialized building services engineering software for precise sanitary and heating calculations. The portfolio centers on two core products: CALHYDRA, which integrates sanitary and heating calculations directly with BIM software for continuous integrated planning, and STUDIO, a standalone CAD solution for graphical planning and calculation of sanitary and heating trades in a single system. The software includes modular calculation functions (drinking water installation, drainage, heat load, pipe networks) along with regulatory compliance validation.

Product overview

DENDRIT (Dendrit Haustechnik-Software GmbH) offers a platform-plus-modules architecture centered on two core products: CALHYDRA and STUDIO. CALHYDRA integrates precision sanitary and heating calculations directly with BIM software for continuous integrated planning, while STUDIO serves as a standalone CAD solution for graphical planning and calculation of sanitary and heating trades in a single system. Both products access a modular set of calculation functions (drinking water installation, heating load, drainage, pipe networks) and output modules (material extraction, hydraulic reports, analyses). The portfolio is supplemented by Product Data on Demand service for BIM-based product data access. The company was founded in 1988 and serves over 21,000 users.

Direct peers

• DDS-CAD: European MEP CAD/BIM software used by building services planners for HVAC, sanitary, and electrical design. Comparable to Dendrit on planner persona, calculation depth, and CAD/BIM workflow.
• Hottgenroth & Co. (ETU Planner): German provider of building services engineering software covering sanitary, heating, and electrical planning with calculation modules. Closely comparable to Dendrit in target customer (TGA planners) and product scope.
• Solarcomputer: Germany-based vendor of HVAC, sanitary, and plumbing calculation/planning software for building services engineers. Competes directly with Dendrit in the same TGA calculation niche in the German market.
• Linear GmbH (Kaufmann / LINEAR): German vendor of HVAC, sanitary, and refrigeration calculation software (LINERAR/LINEAR) for building services planners. Directly competes with Dendrit in the German-speaking TGA calculation market.
• MicroFE (MHK Group): German building services engineering software suite for sanitary, heating, ventilation, and electrical design. Directly comparable to Dendrit on persona, domain, and workflow (TGA calculation + CAD).

Broad incumbents

• Autodesk Revit MEP: Industry-standard BIM authoring platform with MEP discipline tools used by the same building services planner persona as Dendrit. Comparable as the broader incumbent in BIM-based MEP design that could absorb specialized TGA calculation workflows.
• Bentley OpenBuildings: Bentley's OpenBuildings portfolio includes MEP and building services design capabilities serving the same engineer/planner persona. Comparable to Dendrit on BIM planning workflows, but at a much larger, multi-discipline scope.
• Trimble MEP (Plancal Nova): Trimble's MEP design suite (including Plancal Nova heritage) provides multi-discipline HVAC, sanitary, and electrical planning for building services engineers. Overlaps with Dendrit on TGA calculation and BIM workflow but at a much broader, global scale.
• MagiCAD (MagiCAD Group / Glodon): Established European MEP BIM software provider offering HVAC, piping, and electrical design on Revit and BricsCAD platforms. Comparable to Dendrit on BIM-MEP planning but at much broader scale and multi-discipline scope.

Others

• Solar-Computer (alternative: STLB-Bau / buildingSMART): buildingSMART and related openBIM standards bodies shape the interoperability standards that BIM-based MEP calculation tools like Dendrit CALHYDRA rely on. Included as an adjacent ecosystem participant rather than a direct competitor.
