Company portrait

Effin'Art is a consulting firm specializing in climate engineering, design, dynamic simulation and aeraulics. Its goal is to create buildings offering optimal comfort to its occupants while minimizing their impact on the environment. The Effin'Art team is used to work in close collaboration with architects, building owners and other HVAC plumbing and electrical technical consultants in order to assist in developing, but also in following the projects in their construction and commissioning phase.

Our concepts use available passive potential such as daylighting and natural ventilation, advocating the establishment of a bioclimatic architecture, creating climate adapted buildings.

The optimal design energy systems of buildings are also a potential source of significant savings. Our in-depth knowledge of HVAC systems combined with the use of high-performance simulation tools enable us to set up optimal installations in terms of both sizing (cost minimization) and energy efficiency.

Important projects


The BEEP project (Building Energy Efficiency Project, is a project funded by the SDC (Swiss Agency for Development and Cooperation), SDC is part of the Federal Department of Foreign Affairs (FDFA) in charge of international cooperation. the project has embarked on its second phase 2017-2021. Effin'Art is responsible for the technical and administrative management of the project with regard to the Swiss contribution.

Wall-ACE ( is a European project under Horizon 2020. Its objective is to develop an innovative set of new sustainable and advanced insulation systems. Effin'Art is one of the partners of this project and develops simulation methods,  tools, and calculations adapted to these new insulations.

Effin'Art Sàrl is active in the field of building energy and sustainable architecture. Specialized in the fields of energy design, renewable energies and technical installations heating, ventilation and air conditioning. Our company offers the client a high-level, multi-disciplinary approach, both in the design and in the construction phases. It does also follow up with optimization of building operations.

It was founded by Dominique Chuard, Pierre Jaboyedoff and Dario Aiulfi on March 1st, 2014.

For 25 years, they have been participating in a large number of energy research projects in the building industry, passive and active solar energy and in the analysis of energy systems in the most varied fields (production of heat, cold, steam , mechanical and natural ventilation). These research projects have allowed them to create national and international contacts and collaborations and to accumulate over 85 years of experience in these fields.
