Lyon Confluence: satellite data support solar energy production in a sustainable new city quarter

The satellite-based solution costs 1% of the value of the energy annually produced (approx. EUR 125,000) Operating and maintaining the installations without the satellite solution would cost the double, requiring at least one working hour per day on each installation It would take several days to spot malfunctioning that is instantly detected by the system

RENAISSANCE final conference in Lyon

High energy performance buildings for low energy cities

The final conference took place on September 20th and 21st in Lyon, France. The Grand Lyon conurbation has been working on RENAISSANCE since 2005. The project has demonstrated the feasibility of large-scale high energy performance housing and office building construction combined with large integration of renewable energy. The operation covers blocks ABC of the Confluence neighbourhood.

The event has been a great success by bringing together experts from main professions of the building sector : land planners, technicians of municipalities and elected representatives, architects, promoters, energy consultants, constructors, energy manager, property manager, and elected representatives of co-owners.

The first day took the form of a conference organized in round tables. This interactive form gave panellists an occasion to come back on ten years of project history, lessons learnt and, most importantly, challenges they face as we go towards the generalization of low energy buildings. Many project stakeholders as well as professionals working in Grand Lyon which had only little knowledge of RENAISSANCE formed the audience. Thus, the conference has been an opportunity to both capitalize on RENAISSANCE’s experience and disseminate lessons learnt.

The second day, following a two-hour discussion focused on actual challenges of land planning in La Confluence, participants were invited to visit the buildings of the demonstration site. The commented tour of wood fuel boiler rooms, and solar pannels and heat pumps on roofs, with energy managers, gave participants a concrete image of what had been discussed during the previous day.

Live Monitoring for Photovoltaique Systems is now available on RENAISSANCE website

Within the CONCERTO RENAISSANCE project, a district scale PV monitoring tool has been developed by HESPUL.

This monitoring tool can give an easy to understand overview of the good operation of all PV systems of this district as well as the overview of monthly production.

The interface is available to this link:

This interface will be further upgraded in the coming month to include more applications.

Inauguration of the blocks A, B and C in Lyon Confluence area

The construction of the three blocks A, B and C in Lyon Confluence is now finished. As part of the European CONCERTO-RENAISSANCE programme, these 21 buildings, 660 new homes, 17,000 sqm of services and offices, respect specific objectives in terms of energy efficiency and the use of renewable energy sources (more than 80 %).

The inauguration of this "CONCERTO district" will be celebrated with 3 specific events:

- Thursday 14th October: Official Inauguration

The blocks will be officially inaugurated and the partnership between SPLA Lyon Confluence (developer), Grand Lyon and WWF will be declared. Thanks to the RENAISSANCE project, Lyon Confluence area is becoming a Sustainable Area.

Jean-Marie BEMTGEN, European Directorate-General for Energy & Transport and Technical Officer of the RENAISSANCE project, and Gérard COLLOMB, Lyon’s Senator-Mayor and Grand Lyon’s President, will honour us by their presence.

- Friday 16th October: Public Inauguration

That day, local associations are dealing with “Energy / Alimentation / Transport” issues. They will invite Confluence’s and Lyon’s people to be concerned with green behaviour in a convivial atmosphere thanks to stands, exhibitions and activities.

- 14 -16 October: Training Sessions

ALE (Local Energy Agency), a RENAISSANCE partner, will take the opportunity of the event to organize three training sessions for the inhabitants of the Blocks A, B and C. They will present the specificities of their new dwellings and some tips will provide inhabitants on « How to live in an Energy Efficient Building ».
The developed topics will concern: the CONCERTO-RENAISSANCE project, the building’s specificities in terms of energy efficiency, the maintenance needed and finally the way to adopt the required green behaviour.
