Discovering EPIQR+
1982
The origins of EPIQR+
The story of EPIQR+ began in France in 1982. Jean-Louis Genre was presenting his diploma in architecture on the renovation of the historic centre of the town of Aubagne in the south of France.
That's how he discovered the MER Rapid Estimation Method, published by the Direction de la Construction, which enabled him to draw up an inventory of existing buildings in his study area as the first basis for his diploma project.
1989
Development of the MER 60 method
In 1989, in Geneva, he met Professor Pierre Merminod, who was familiar with this French method and who was working on an adaptation of the MER OFL method for the Swiss building stock built from the 1960s onwards. Professor Merminod then recruited him as an assistant in the development of the MER 60 method.
Development of the MERIP method
On Professor Merminod's retirement, Jean-Louis Genre joined the EPFL's Solar Energy Laboratory (LESO) and worked on developing the MERIP method as part of the PIBAT programme set up by the Federal Office for Economic Affairs. The aim of this federal government programme was to develop new decision-making tools for architects and others involved in the renovation of residential buildings.
1996
Birth of the EPIQR method
The MERIP method was a great success in Switzerland, particularly in the French-speaking part of the country and in Ticino, and in 1996 it formed the basis of the European EPIQR Energy Performance Indoor Quality and Retrofit project, in which EPFL's LESO and five other European research institutes collaborated to develop the EPIQR method.
1998
Placing EPIQR on the market
He met Flourentzos Flourentzou, a doctoral student at LESO, with whom he collaborated on the EPIQR project, which came to fruition in 1998 with the launch of the new EPIQR decision-support tool.
1998 and 2001
Birth of ESTIA and EPIQR Rénovation
ESTIA was created in 1998 and EPIQR Rénovation in 2001, and since then these two start-ups, based in EPFL's Innovation Park, have been working together on appraisal and analysis assignments for institutional, public and private property assets, as well as continuing to develop EPIQR, culminating today in the launch of the online version EPIQR+ web.

Architect Jean-Louis Genre founded EPIQR Rénovation Sàrl in June 2001.
After obtaining his diploma as a DPLG architect in 1983 from the Unité Pédagogique d'Architecture de Marseille Luminy (UPAM), Jean-Louis Genre was put in charge of private renovation projects as part of the renovation of the old town centres of Aubagne and Marseille Belsunce.
In 1989 he moved to Switzerland and worked with Professor Pierre Merminod on the development of the MER 60 method as part of a research project funded by the Office Fédéral du Logement (OFL).
In 1991 he joined the Solar Energy Laboratory (LESO) at EPFL, where he played an active part in developing the MERIP diagnostic method (OFQC PIBAT programme - 1990 to 1995).
In 1996, he was the instigator of the European EPIQR project, a European extension of the MERIP method, financed by the European Community and the Federal Office for Education and Science (OFES). Together with Professor André Faist, he coordinated and developed the project.
Flourentzos Flourentzou
Dr. ès Sciences, Associate Director Estia SA
Flourentzos FLOURENTZOU is an energy engineer, associate director and founding member of Estia. His areas of expertise include multi-criteria decision support, bioclimatic architecture, particularly natural ventilation and cooling, renovation and property strategy.
Originally from Cyprus, he started out as a mechanical technician and then broadened his studies in France with a diploma in energy engineering from the Mines de Douai and a master's degree in fluid mechanics from the University of Valenciennes. He became interested in the social sciences with a master's degree in development studies at the UniGe and completed a doctorate at the EPFL.
He took his first steps as a researcher in bioclimatic architecture at the Solar Energy and Building Physics Laboratory (LESO-PB / EPFL) before setting up Estia with his partners in 2002.
A keen researcher, he has not stopped since his first projects at LESO on passive cooling (Pascool), renovation (first EPIQR programmer), property strategy (Investimmo) and subsequently at Estia for 25 years: EPIQR+ for any assignment, Albatros - initial choices for sustainable development, CoolingVent - climatic resilience with ventilation cooling, OptiRen - gap performance, ReCO2st - optimal choices for renovation, E-DYCE - precise energy labels that make sense, PRELUDE - works roadmap for transitional renovations...
He has followed EPIQR's development from 1998 to the present day with the same passion.
