Onhaus Global System

What Onhaus Global System does

Onhaus Global System is a Navarra, Spain-based specialty distributor and consulting firm focused on Passivhaus and ECCN (Eficiencia y Control del Consumo Normativo) construction standards, founded in 2009 and operating as a Sociedad Limitada (S.L.) with roughly 10 employees. The company serves architects, developers, installers, and end homeowners across the Iberian Peninsula, supplying high-performance building components through seven official international brand partnerships — Zehnder (ventilation), Panasonic (heat pumps), Griesser (solar shading), SIGA (sealing), Wienerberger (ceramic), Schöck (thermal breaks), and Schneider (electrical). Beyond wholesale distribution, Onhaus runs an e-commerce retail channel and earns revenue from project consulting, technical specification support, the Traininghaus applied Passivhaus academy, and a recurring filter-replacement subscription tied to its installed base.

The firm's commercial proposition centers on being a one-stop technical channel for near-zero-energy and Passivhaus-compliant construction, including the proprietary "Espacios Healthy" indoor-environment concept and the ONHAUS RETROFIT diagnostic program developed with HOBEKI TECHNIK. Notable reference projects include the Torre Zaragoza development (285 dwellings), the Canfranc Station rehabilitation, Iruraiz Town Hall, a Madrid co-living building, and a single-family home in Zolina. Onhaus has received external recognition including the Edifica 2023 Rehabilitation Award, GDPR/LOPD certification, and a 2025 competitiveness subsidy from the Government of Navarra, and is positioning itself for expansion beyond Navarra into national and broader European markets. The company is led by CEO Koldo Monreal.

The business model blends four revenue streams: (1) wholesale distribution of partner-brand products to construction professionals, (2) e-commerce retail to individual consumers, (3) project-based consulting and specification fees, and (4) recurring filter-replacement subscriptions. The combination of training, proprietary concepts, and exclusive brand distribution is intended to anchor the firm in the specification chain for high-performance residential and public-sector projects in Spain.

Broad incumbents

• Schöck Bauteile GmbH: Schöck is a German manufacturer of thermal break solutions (Isokorb) widely specified in Passivhaus and ECCN construction. ONHAUS is an official Spanish distributor of Schöck products; Schöck represents the type of specialist component manufacturer that competes for specification share in the thermal-bridge category.
• Daikin Europe: Daikin is a global HVAC and heat-pump manufacturer with major European operations. Comparable to Panasonic (an ONHAUS supplier partner), Daikin represents broad-incumbent competition in aerothermy and air-conditioning categories where ONHAUS provides specification, distribution, and integration services.
• Rockwool A/S: Rockwool is a global manufacturer of stone wool insulation and a broader building-envelope solutions provider. Comparable to ONHAUS in addressing the high-performance building market through insulation and facade systems, but Rockwool operates at vastly greater scale and broader product breadth.
• Zehnder Group: Zehnder is a Swiss-listed manufacturer of indoor climate solutions, including the ComfoAir ventilation units with heat recovery that ONHAUS distributes. Zehnder serves as both a core supplier partner and a broad incumbent — a manufacturer that could potentially bypass distribution in some channels, but whose brand ONHAUS leverages for technical authority.
• Sto SE & Co. KGaA: Sto is a European broad incumbent in facade systems, ETICS, and high-performance building envelopes. Comparable to ONHAUS at the building-envelope and energy-efficiency specification layer, but operating at far greater scale with vertically integrated product portfolios rather than distribution-led models.
• Vaillant Group: Vaillant is a European broad incumbent in heating, heat pumps (aerothermy), and hot water systems — directly comparable to Panasonic products distributed by ONHAUS. Both compete for the heat-pump specification layer in residential and commercial energy-efficient projects across Spain.
• Saint-Gobain ISOVER: ISOVER (Saint-Gobain) is a broad European incumbent in mineral wool and high-performance insulation products used in Passivhaus and ECCN construction. ONHAUS competes with ISOVER in the insulation specification layer and complements it via complementary airtightness, ventilation, and solar-control offerings for the same high-performance building projects.
• Knauf Insulation: Knauf Insulation is a European broad incumbent in glass and stone wool insulation and high-performance building envelope systems. Comparable to ONHAUS via complementary product categories (insulation, airtightness, building science) for Passivhaus and ECCN projects across European markets.

Direct peers

• pro clima (Moll bauökologische Produkte GmbH): pro clima is a leading European specialist in airtightness and weatherproofing membranes for high-performance buildings, including Passivhaus-standard products. Like ONHAUS, pro clima combines proprietary building-envelope systems with strong technical content, training, and consulting support for installers and architects across DACH and other European markets.
• SIGA Cover AG: SIGA is both a supplier partner and a direct comparable: a Swiss manufacturer specializing in airtightness and windtightness membranes, tapes, and adhesives. ONHAUS distributes SIGA products in Spain; SIGA represents the type of specialist building-envelope brand ONHAUS competes with indirectly via its own technical specification and consulting services.
