Effin'Art

What Effin'Art does

Effin'Art Sàrl is a privately-held Swiss climate engineering consulting firm headquartered in Crissier (Lausanne region), with a branch office in Biel/Bienne. Founded by Dominique Chuard, Pierre Jaboyedoff, and Dr. Dario Aiulfi—engineers collectively holding over 100 years of experience in building energy research—the firm specializes in energy concept design, building physics, HVAC (heating, ventilation, air conditioning, refrigeration) engineering, daylight analysis, and renewable energy integration for new construction and renovation projects. Core technical capabilities rely on advanced simulation tools including TRNSYS 17 with the TESS library, DesignBuilder, CFD packages (FloVENT, PyroSim), daylight modeling (Relux, Diva), and energy balance tools (Lesosai, PVsyst, Polysun) to validate building performance against Minergie, SIA, and CECB certification standards.

The firm's business model is project-based professional services consulting, with fees quoted per engagement rather than through disclosed standardized pricing. Effin'Art operates a sales-led go-to-market motion, acquiring work through professional networks, architect relationships, and reputation in the Swiss energy efficiency sector. The customer base spans healthcare (Cité Générations Hospital), luxury manufacturing (Greubel Forsey), residential real estate (Les Allières – 297 apartments), pharmaceutical (Celgene Couvet), cultural/museum (MUDAC & Musée de l'Elysée), media/broadcasting (RTS SSR), education (EPFL Learning Center), and government (SIC Givisiez, IHEID Maison de la Paix). Long-standing multi-year engagements, such as the RTS SSR relationship dating back to 2004, indicate recurring institutional client work.

Effin'Art operates with approximately 18–20 professionals across two offices, generating revenue through consulting engagements primarily in Switzerland (French and German-speaking regions), with selective international exposure via the Indo-Swiss Building Energy Efficiency Project (BEEP) in partnership with the Swiss Agency for Development and Cooperation (SDC) and India's Bureau of Energy Efficiency (2012–2022). The firm holds no external investment, maintains no parent company or subsidiaries, and operates as a founder-led partnership without public listing or external funding rounds.

Products and services

• Energy Concept Design and Climate Engineering Consulting Core climate engineering consulting service designing energy concepts that limit energy needs while respecting occupant comfort criteria. Delivered to architects, maîtres d'ouvrage, and other technical CVCSE offices for both new construction and renovation projects, covering the full project lifecycle from conception through construction supervision and commissioning.
• Building Physics Engineering Consulting Building physics consulting including thermal performance analysis, hygrothermal analysis, and building envelope engineering for new construction and renovation projects. Supports Minergie P, Minergie A, and Minergie ECO certification pathways across diverse building types including hospitals, residential, industrial, and cultural institutions.
• HVAC (CVC/CVCF) Systems Engineering Design and engineering of heating, ventilation, air conditioning, and refrigeration (CVC/CVCF) systems optimized for both installation size (cost minimization) and energy efficiency. Includes sizing of installations, system selection, and technical specifications for projects ranging from residential Minergie buildings to pharmaceutical production sites and luxury manufacturing.
• Natural Ventilation and Daylighting Studies Specialized studies using simulation tools (Relux with radiance, Dial+ with radiance, Rhino 5, Diva 3) to evaluate natural ventilation potential and daylight availability in buildings. Supports bioclimatic architecture design that adapts to local climate rather than opposing it, leveraging passive potentials to minimize energy needs.
• CFD and Smoke Extraction Simulations Computational Fluid Dynamics (CFD) simulations using FloVENT and PyroSm tools for detailed air movement calculations inside and around buildings, including smoke extraction simulations for fire safety engineering. Delivered as a value-added engineering service in support of building physics and HVAC projects.
• Dynamic Thermal Simulation and Energy Modeling Building energy modeling using TRNSYS 17 with TESS library and DesignBuilder to perform dynamic thermal simulation of buildings and energy systems. Used to validate energy concepts, predict heating and cooling loads, and optimize building designs against Minergie and other Swiss energy standards.
• Renewable Energy Systems Consulting Consulting services for renewable energy systems using PVsyst (solar PV installations) and Polysun (renewable energy systems simulation). Includes solar production sizing, photovoltaic installation design, and integration of renewable energy into building energy concepts, with documented outcomes including over 613,000 kWh annual solar production at SIC Givisiez.
• Energy Balance and Certification Consulting (Minergie, CECB) Comprehensive energy balance calculations using Lesosai software combined with certification expertise in Minergie (P, A, ECO variants) and CECB (Cantonal Energy Certificate for Buildings) standards. Supports project owners in achieving Swiss energy efficiency certifications and regulatory compliance.
• Construction Supervision and Commissioning Services Owner assistance, construction supervision, and project follow-through services delivered from the design phase through implementation and commissioning. Includes suivi de projet (project follow-through) and mise en service (commissioning) of HVAC and energy systems to ensure installed systems perform as designed.
