What leBird does

leBird Sàrl is a Swiss engineering consultancy founded in 1992 and incorporated as an independent legal entity in September 2016, headquartered in Prilly-Lausanne with a secondary office in Geneva. The firm specializes in sustainable resource management across the built environment, operating through six practice areas: sustainable construction (including Minergie-Eco, SNBS, and SmeO certification support), energy and building physics (audits, CECB/CECB+, Minergie), building pollutant diagnostics (asbestos, PCB, lead, PAH, HBCD), construction-site environmental monitoring and waste management, end-of-life electronics valorization (approximately 1,200 tonnes per year), and ancillary consulting on CSR, occupational health, and recycling-center planning. The firm has completed over 800 building pollutant diagnostics since 2004 and reports waste valorization rates above 60% for new construction and above 80% for deconstruction projects.

The company is co-directed by Sébastien Piguet and Anne-Claude Imhoff, both EPFL-trained environmental engineers, with a multidisciplinary team of roughly ten specialists holding federal and industry credentials (Minergie controllers, CECB experts, STPS workplace-safety patent holders). leBird is ISO 9001/14001 certified since 2005, serves as Romandie director for ecobau, and participates in the SIA KNU sustainability commission. Approved as a recycler under both the Swico (since 1994) and Sens (since 1994) compliance schemes, and operating in consortium with Thommen Bex plus social-employment partners (Fondation Mode d'emploi, Olbis Les Ateliers), leBird operates within a regulated, certification-heavy Swiss market.

The business model is project-based professional services, delivered directly by specialists within an approximately 60 km radius of each office and billed via free, non-binding quotes. Revenue is concentrated in French-speaking Switzerland across property owners/developers, construction companies, public administrations/municipalities, and companies/institutions requiring e-waste compliance. No external funding, M&A activity, subsidiaries, or disclosed revenue figures are present in the available data.

Core offering

leBird is a Swiss engineering consultancy specializing in sustainable resource management for the construction sector. Core offerings include energy audits and building physics assessments, building pollutant diagnostics (asbestos, PCBs, lead, PAHs, HBCD), sustainable construction certification support (Minergie-Eco, SNBS, SmeO), construction site environmental monitoring and waste management, and end-of-life electronic equipment recycling through social-partner disassembly workshops. Services are delivered as project-based consulting engagements billed via free, non-binding quotes to clients across French-speaking Switzerland.

Product overview

leBird offers a portfolio of engineering consulting services for sustainable resource management in construction. The services are organized into six main practice areas: Construction durable (sustainable construction certification and consulting), Energie et physique du bâtiment (energy audits and building physics), Amiante et polluants du bâti (asbestos and pollutant diagnostics), SER et déchets de chantier (construction waste management and environmental monitoring), Valorisation des appareils électroniques (e-waste recycling), and Autres conseils (additional consulting services). These services operate as distinct but complementary consulting offerings delivered by a multidisciplinary team of engineers, rather than as a unified software platform.

Direct peers

• BG Ingénieurs Conseils: Swiss engineering consultancy with multi-disciplinary practice including building energy, environment, and sustainable construction. Comparable to leBird on engineering service mix and Romandie/D-CH geographic footprint, with a much larger headcount.
• Amstein + Walthert: Swiss engineering consultancy with one of the largest sustainable building, energy, and building-physics practices in Switzerland. Closely comparable to leBird in offering energy audits, CECB, Minergie, and building physics services, but at materially larger scale across multiple cantons.
• Holinger: Swiss engineering consultancy active in environment, energy, water, and waste — directly comparable to leBird's environmental engineering and resource management services, with a similar sustainability/regulatory positioning and Pan-Swiss footprint.
• Eicher + Pauli: Swiss energy and sustainability engineering consultancy covering building energy, CECB, Minergie, and resource optimization. Strong functional overlap with leBird's Energie et physique du bâtiment and Construction durable practices.
• CSD Ingenieurs: Swiss engineering firm advising on environment, energy, sustainable construction, and waste/resource management. Highly comparable to leBird's portfolio (energy, pollutants, waste valorization) and a routinely named competitor in Romandie and across Switzerland.
• Weinmann-Energies: Swiss energy and building-physics consultancy offering CECB, Minergie, and thermal/energy audits. Directly comparable to leBird's Energie et physique du bâtiment service line and serving the same Romandie and Vaud/Fribourg market.

Broad incumbents

• Bureau Veritas: Global TIC incumbent with established Swiss operations in building certification, environmental compliance, and ESG advisory. Overlaps with leBird's certification and environmental compliance work, but at much larger scale and broader scope.
• SGS: Swiss-headquartered global testing, inspection, and certification company with overlapping environmental and sustainability advisory services. A broad incumbent that competes for larger ESG/ISO/sustainability mandates that leBird might otherwise serve.

Emerging players

• Thommen Bex: Swiss e-waste recycler and consortium partner of leBird for electronics valorization. Partial overlap on the WEEE/electronics recycling stream of leBird's offering, with cooperation in some client engagements coupled with separate competition in others.
• Planair: Swiss sustainability and energy consultancy with SMEs and public-sector focus. Partial overlap with leBird on energy, decarbonization, and circular economy consulting, typically operating at smaller scale in Romandie and Western Switzerland.
