Hausler Ingenieure

What Hausler Ingenieure does

Häusler Ingenieure AG is a privately held Swiss engineering consultancy headquartered in Langenthal, Canton of Bern, with approximately 50 years of operating history. The firm specializes in HLKKS building technology planning — covering heating, ventilation, climate, refrigeration, and sanitary systems — for new construction, renovation, and energy optimization projects in northwestern Switzerland. Core service lines include GEAK-certified energy consulting (Gebäudeenergieausweis der Kantone, the cantonal building energy certificate), Building Information Modeling (BIM)-enabled planning, photovoltaic (PV) system design, and general building services engineering. The firm holds ISO 9001 quality certification through SQS and engages in vocational training partnerships via the State Secretariat for Education, Research and Innovation (SBFI).

The firm's client base spans three segments: municipalities, residential developers, and hospitality operators, with regional concentration in Canton of Bern and adjacent northwestern Swiss cantons. Project-based delivery is supported by a small team (1-10 employees per firmographic classification), with revenue mechanics reflecting fee-for-service engineering work rather than recurring software or platform contracts. Recent capability investments include BIM digitalization and PV system planning, indicating incremental product surface expansion aligned with Swiss energy transition and digitalization trends in the AEC sector.

The business model is traditional specialist engineering consultancy: revenue is generated per project through municipal procurement, developer mandates, and hospitality retrofit engagements, with quality assurance underpinned by GEAK accreditation and ISO 9001 certification. There are no disclosed funding rounds, recurring SaaS subscriptions, or platform revenue lines. A leadership succession announced in December 2023 takes effect January 1, 2026, marking a generational ownership transition. The firm's competitive positioning is regional, specialist, and depth-driven rather than scale-driven, limiting addressable market but providing regulatory-driven defensibility through accredited energy and quality certifications.

Core offering

Häusler Ingenieure AG is a Swiss engineering consulting firm that plans and coordinates building technology systems (HLKKS — heating, ventilation, air conditioning, refrigeration, and sanitation) for residential, commercial, industrial, and public-sector buildings. The firm complements these planning services with energy concepts, certified energy consulting (GEAK/GEAK Plus), BIM-based digital planning, photovoltaic system design, and water fire-extinguishing system engineering. Engagements are delivered as project-based professional services to clients across Northwestern Switzerland.

Product overview

Häusler Ingenieure AG is a Swiss engineering firm offering integrated building technology planning and energy consulting services. The core offering is Gebäudetechnikplanung HLKKS (HVAC building technology planning) which includes specialized sub-products for heating/cooling, ventilation/air conditioning, and sanitary systems. This is complemented by Fachkoordination (specialist coordination) services. On the energy side, the company provides Energiekonzepte (energy concepts) and Energieberatung (energy consulting) services including GEAK certification, SME energy consulting, building energy analysis, and thermal imaging. Additional services include BIM-Planung (BIM planning), Wasserlöschanlagen (water fire extinguishing systems), and Photovoltaik (photovoltaics). The portfolio operates as a unified service offering rather than a modular software platform, serving residential, commercial, industrial, public, and healthcare building projects across Switzerland.
