Bouygues Construction and LogiRep sign France’s first energy performance contract in the social housing sector

LogiRep, a subsidiary of the Polylogis group, has signed the first Energy Performance Contract (CPE) for social housing in France with Bouygues Bâtiment Ile-de-France and ETDE. A consortium(1) led by Brézillon, a subsidiary of Bouygues Bâtiment Ile-de-France, is responsible for designing, modernising and extending a social housing development in Vitry-sur-Seine (southern suburbs of Paris) containing 231 flats, and for maintenance of the energy equipment system for four years.

Under the terms of the French "Grenelle" round-table conference on the environment, held in 2007, the project, worth 9 million euros (4 million euros of energy renovation works and 5 million euros of internal renovation of the accommodation), qualifies for optimised funding through State financial mechanisms to aid social housing, specifically the decree concerning the share-out of energy savings. Works will be launched early in 2011, and are scheduled to last 24 months. 

The first French CPE in social housing

The consortium is committed to achieving a specified level of energy saving. To this end it is collaborating on the definition of the works programme at a very early stage and will check the reality of the intended level of performance by taking measurements post-delivery.

Prior to launching the call for bids, LogiRep performed a thermal diagnosis and a feasibility study, identifying the quality certification levels to be achieved and potential sources of funding.

This CPE is structured in three phases: 

•    Design: a programme of works will be determined and the hypotheses of the feasibility study phase validated or fine-tuned (the desired level of performance, cost and length of works, a guarantee of improved living conditions, the combination of comfort and energy savings, etc.) 

•    Modernisation works: thermal insulation of facades, balconies and floors, replacement of external doors, windows and shutters and heating equipment. 

•    Maintenance: the consortium will analyse energy consumption, monitor energy performance and carry out follow-up over time. 

To ensure that tenants are fully implicated in the project, an innovative social approach will be introduced: 
•    Raising tenants' awareness of eco-performance programmes, 
•    Distribution of a booklet setting out all possible areas of action to reduce energy consumption while retaining a genuine level of comfort, 
•    Design of a support plan for tenants, devised in collaboration with specialist sociologists, 
•    Sharing of good practice through a dedicated website for tenants. 
The first renovation project in France that meets "Grenelle" specifications

This is the first project to meet the targets set at the "Grenelle" environment round-table conference: 

•    40% reduction in real energy consumption, guaranteed by the consortium, 

•    Cutting of greenhouse gas emissions by a factor of 4, 

•    Creation of accessible homes for people with disabilities, 

•    Possible creation of additional space (up to 25%) through added height or extensions. 

This contract illustrates Bouygues Construction's strategy with regard to sustainable construction and renovation. In October 2010, Bouygues Construction established and funded a research and teaching chair in "Sustainable Building and Innovation" in partnership with three engineering schools and their respective foundations (Ecole des Ponts Paris Tech, Ecole Centrale Paris and Supelec) and the French Scientific and Technical Centre for Building (CSTB). The chair will support research into low-carbon technologies, sustainable buildings and sustainable neighbourhoods and towns.

Sustainable development has been an overriding priority for LogiRep for some years. It has proactively signed quality commitment charters with the Cerqual certification agency (a subsidiary of Qualitel) which aim to achieve the greatest possible energy efficiency by applying innovative projects to both its new and existing housing stock. Through the signature of its first CPE in Vitre-sur-Seine with Bouygues Construction, LogiRep is able to leverage the progress made by its development department and is now applying its expertise to the renovation of its existing housing stock. 

(1) The consortium consists of Brézillon (lead company), ETDE and its subsidiary Cogemex, the architects Lair and Roynette and CET Ingénierie.
