What Planair does

Planair SA is an independent Swiss engineering consultancy founded in 1985 in La Sagne, Neuchâtel, specializing in energy and climate transition services. The firm operates across three service domains — Sustainable Buildings (Bâtiments durables), Efficient Industries (Industries efficientes), and Resilient Territories (Territoires résilients) — serving collective building owners, industrial enterprises, and public collectivities with multidisciplinary expertise spanning building physics, HVAC, photovoltaics, geothermal, biomass, and energy strategy. Planair delivers the full project lifecycle from conception through execution oversight (maîtrise d'œuvre) and long-term monitoring, and also provides professional training (RTEB program), AMO energy advisory, and a free Conseil Incitatif service under the Suisse Energie Chauffez Renouvelable program for collective building owners with aging heating systems.

The business is project-based professional services, with the bulk of revenue generated through quote-driven engineering consulting engagements and a smaller but visible training and free-advisory layer funded through Suisse Energie. Distribution is direct, delivered through 10 regional offices (7 in Switzerland — La Sagne, Givisiez, Carouge, Delémont, Martigny, Yverdon-les-Bains, and Prilly — and 3 in France — Besançon, Lyon, and Chambéry), with no intermediary channel. Go-to-market emphasizes thought leadership through white papers, conferences, and webinars, supported by senior staff holding international leadership positions at IEA PVPS and IEA Wind Task 11. The customer portfolio is distributed across Swiss and French municipalities, hospitals, departmental energy syndicates, and branded enterprises such as Victorinox and Gaznat, with international development work in Côte d'Ivoire and French Polynesia.

Planair is privately held with no disclosed external investment. The firm employs approximately 150 people, is ISO 9001 and ISO 14001 certified, and is recognized as a Swiss training company (entreprise formatrice). In June 2026, Lionel Perret succeeded François Bauer as Director General, signaling a planned leadership transition coinciding with the company's 40th anniversary.
