What Enerplan does

Enerplan AG is an independent Swiss engineering firm specializing in energy and building technology (HLKS — heating, cooling, ventilation, climate, sanitary) and installation planning, founded in 1981 and headquartered in Ostermundigen (Bern). The firm operates four regional offices across German-speaking Switzerland (Bern, Solothurn, Olten, Zürich) and serves property owners, developers, architects, and general contractors with specialist planning, specialist coordination, construction management, and optimization services. In December 2023 it expanded by integrating Häusler Ingenieure AG into its corporate structure as a succession arrangement.

The company's service portfolio spans the full building-technology lifecycle — from feasibility and energy-concept studies through detailed engineering of HVAC, sanitary, and MSRL (measurement, control, and regulation) systems to construction supervision and operational optimization. It employs Building Information Modeling (BIM) as its core digital planning methodology, supported by an internally developed quality management system (PQM). The firm is a certified Minergie planning partner and is credentialed under GEAK and Suissetec, positioning it for energy-efficient and sustainability-driven building projects. Its reference portfolio covers enterprise clients across banking (Raiffeisenbank Muri), logistics (Schöni Transport AG), automotive/transport (Mobilcity Bern), residential development (Halter Entwicklungen, Sommerrain/Real Stone, Previs Vorsorge), and other commercial segments.

Enerplan generates revenue through professional services billed on a project-specific, quote-based model. It is family-owned, with 100% of shares held by Polyplan Holding AG and employees (the latter via a partner-share program available after five years of service), and reports a team of 40+ including management, department heads, project leaders, BIM coordinators, and apprentices. Pricing is not publicly disclosed; the firm's go-to-market is sales-led, driven by direct engagement with property owners, architects, and general contractors and supported by project references, industry certifications, and professional referrals.

• Suter + Partner AG: Swiss building services engineering firm (Heizung, Lüftung, Klima, Sanitär, MSRL). Comparable multi-discipline, project-based consulting model serving commercial and residential developments in Switzerland.
• Amstein + Walthert AG: Largest independent Swiss engineering firm for energy, building technology, and infrastructure. Closest direct peer to Enerplan with comparable HLKS, building automation, and BIM services across multiple Swiss locations.

Broad incumbents

• EBP Schweiz AG: Larger Swiss engineering, planning, and consulting firm with building energy and HVAC advisory practices. Broad incumbent overlap on energy concept and building services consulting, though with a much wider service portfolio.

Regional players

• Polke Engineering AG: Swiss engineering firm specializing in HLK and sanitary planning. Comparable mid-sized regional consultancy profile, though typically focused on a narrower regional footprint than Enerplan.
• Waldhauser + Hermann AG: Munich-based building-services engineering consultancy with deep HLKS planning practice. Comparable technical scope and mid-sized firm dynamics, but serves southern Germany rather than Switzerland.

Emerging players

• planen und bauen GmbH: Smaller Swiss planning office offering HLKS engineering services. Comparable service portfolio but smaller scale; represents the niche/emerging tier Enerplan itself sits in or could acquire.
