Site

The  project aims to participate to the objective of 15% RES in 2010 in the energy balance of the Great Lyon . RE-Start concerns :

  • Energy efficiency and renewable energy program in the building sector

  • photovoltaic installation

  • building sector

At urban scale, the objectives are:

to decrease energy consumption of new buildings with low environmental impact

to decrease or even eliminate the over-cost of RES with efficient techniques for building

 

RESTART project concerns 200 dwellings in the social housing sector in 7 independent projects in social housing sector.

Design Concept

  • A mandatory guidebook of specification

  • Information on technologies for architects and engineers

  • An engineer at the disposal of the social housing organisation to help the design and to follow the construction according to RESTART specifications

  • An inter-sectoral working group to discuss the obstacles and to evaluate the dissemination at urban scale

In order to help the coordination of the project, a common guidebook for the design of efficient buildings has been developed and proposed to the public housing organisations partners of RESTART

The guidebook is based on the following elements:

A global approach on architecture, energy, water, environment applied to the design of social housing.

A targeted decrease of the total cost of energy and water for the occupants, the total energy plus water charges should not exceed 12,20 € /m²/year with a better comfort with specifications for the design of the buildings:

• 20 compulsory measures: for example on architecture, acoustic, thermal comfort, reduction of air pollution, water savings, lighting, wastes, maintenance

• 6 options (1-direct solar water heating system, 2-solar hot water, 3-green houses, 4-DSM, 5-water recovery from rain,6-improvement of insulation). The designers have to choose at least one option among the firsts 3 options, and one among the last 3 )

• the possibility to develop photovoltaic applications if possible

It was expected that the combination of these measures reduces the energy consumption by 30 to 40%, while the total cost for energy and water is reduced by 40 to 50%.

To develop the guidebook, different meetings with persons in charge of social housing organisations have been organised. Some modifications of the guidebook have been integrated to take into account specific problems. During the design phase of the project, the guidebook was the basis for the specifications of the buildings.

RESTART guide book is now the reference for the building sector in Great Lyon, this is a very important success for the RESTART project.
 

Construction Innovation

 

1. The project Cours Jean Damidot -Villeurbanne is situated in an urban area, near many facilities, primary schools, house of association, swimming pool and shops. The building is designed for the users particularly children, as they will have green spaces separate from streets and located on the south facade.

·          17 dwellings

·          green house

·          20 m2 solar collectors

 

2. Les Fossés de Trion - Lyon building is situated in a periphery urban area, well equipped: primary schools, colleges, high school, hospital, university, theatre, swimming pool and shops. However, the location is better adapted to car users than pedestrians. Buses are available but cycling is difficult because of the characteristics of the site.

·          49 dwellings

·          27 greenhouse

·          60 m2 solar collectors

 

3. The building project Place Antoinette/Cours Vitton is situated in an urban area with an average rate of public equipment: primary schools, sport centre and shops. Green spaces are located on the north side due to urban continuity constrains.

·          25 dwellings

·          40 m2 de solar collectors

 

4. The project Avenue Berthelot is situated in an urban area, near many facilities, primary schools, university, hospital and shops. The building is designed for the users, particularly children, as they will have green spaces separate from the street and located on the south facade.

·          40 dwellings with:

·          40 greenhouses

·          75 m² solar collectors

 

5. Rue Léon Blum Villeurbanne is situated in an urban area, near many facilities, primary schools, house of associations, swimming pool and shops.

The building is designed for the users particularly children, as they will have green spaces separate from streets and located on the south facade.

·          19 dwellings with:

·          15 greenhouses

·          low water and energy consumption

 

6. ZAC des Balmes is situated in an urban area with classical equipment: school, sport centre, shops. Every house has its own garden.

·          36 houses

·          22 Solar Heating System by floor (PSD)

 

7. The project in street Pierre Delore is situated in the Urban area with good south orientation. It has 5 levels.

·          27 dwellings

·          54 m² of solar collector

Photovoltaic
For Photovoltaic, the initial proposal has been discussed with a revision of the performance of the installation and a reduction of the costs of investment. The photovoltaic panels were installed on the roof of the thermal engineering department of INSA (School of engineers of Lyon).

The photovoltaic project was a part of a global project:

INSA has a global strategy to improve energy efficiency of there buildings, particularly lighting.

The students of the thermal department are involved in the project, from the very beginning to the final installation.

This project is also a good opportunity to work with the enterprises of the photovoltaic sector for a larger development of such applications in urban areas. A part of the budget has been dedicated to communication and information.

It demonstrates the feasibility of this technology and helps the development of such technologies at urban scale.

  • Finally, the main dimensions of the project can be summarised as followed:
    photovoltaic panels in the south facade with special care for the architectural aspects of the project ( 70 m² - 7 kWp)

  • in winter the electricity production is used for the lighting of common areas with information panels to explain the technology

  • in summer the energy is used for air conditioning installation

  • the project is made in relation with INSA who is in charge of measurements. The installation is used to train students on this technology.
