    • A study in 2006 by the Citémétrie cabinet that was intended to prepare an inventory of the housing situation
    In conclusion, this project is led by an atypically Department in line with the recommendations of the Grenelle Environment Forum on governance and the participation of all institutional actors, associations and citizens.

Mobility strategy

In the document project organization framework (Charter of environmental quality and sustainable development), one of four selected priority themes addresses the accessibility.

A multidimensional accessibility

Implementation of consultation and use of expertise on disability issues with APF in paths and movements (privileged partnership) As such a work in permanent consultation with the Association for the Paralysed France Cher is to discuss issues paths in the eco-neighborhood.

A controlled use and secure car

Quad hospital Baudens is defined by the paths that surround (Av Gionne, Ranchot street, street Abbot Moreux Boulevard du Maréchal Joffre, red traffic lanes on the plan). Each component of the project is well serviced by one of these streets creating a neighborhood in which motorized traffic are favored. Thus space is meshed with a gentle frame pedestrian and cycle lanes (yellow tracks on the traffic plan). A service road enters the area to allow access to the parking and housing, it is a shared space without barriers to slow traffic (blue route). This development will favor pedestrians and soft modes of transport (bicycles, scooters ...), proximity to downtown and services allow residents to reduce car dependency. Parking will also be organized to forget the presence of the car, 2/3 of the vehicles will be underground parking and air car parks will be landscaped.

  • Good connection to public transport (bus + 4 + pedibus FREE shuttle connecting to the city center every 15 minutes) and promotion of cycling inducing a limited role of the car in the neighborhood.
  • 1.43 parking / logt
  • 100% coverage by the TC (% dwellings within 500m of a public transport stop)

As for public transport discussions are in progress in the renewal of the Urban Transport Plan with Bourges Plus (agglomeration), on a possible extension of the free shuttle to the site of the eco-neighborhood (extension of 'Séraucourt stop Baudens).

Regarding soft movements there is currently a walking bus on the Beaumont school which is located near the eco-neighborhood.

The city of Bourges has developed sleeves for fiber optics systematically during the requalification of roads. She also close social landlords for housing can connect to it without difficulty.

  • She will be present on the site and will allow its future residents, employees and visitors to benefit from a significant connectivity for leisure, professional activities, daily life etc.

  • Development Wifi

Water management

The rainwater is discussed in the context of environmental quality and sustainable development charter in the "environ-mental quality of the neighborhood."

Creating valleys

  • After additional studies and simulations undertaken under the aegis of the developer an additional valley was created near the future building of Pôle Emploi.

Preservation of water resources in the 110 rental units

  • A limitation of the discharge of stormwater
  • Retention basins thunderstorms before infiltration buried underground

Waste management

Special care is given to the sustainable management of sites (demolition, construction, management).

A first exemplary construction operation in waste management term "green construction"

Biodiversity and natural areas

A sober territory + accompanying changes

An interesting natural heritage showcase

  • This 5-hectare site includes a tree heritage with interesting topics that have been the subject of a census and a health diagnosis.

Creating a new green space

  • Garden Leeward appears as a green space walk privileges while allowing to cross joining the neighborhood and Avenue Gionne Ranchot the street. This opening will be new because the site is surrounded by a wall, pedestrians should completely bypass to get from one point to another of the aforementioned streets.

Outdoor spaces

  • The treatment of external areas will be landscaped in its own project, integrating environmental and landscape quality objectives. It is important to ensure the diversification of species that will be up to local plants that consume little water, landscape enhancement of alternative management arrangements Rainwater (valleys). While being attentive to facilitate the management and maintenance of facilities (plantations consume little water, size limitation and the amount of green waste). This also includes work on street lighting and night environments.

Creating a new educational green area

  • A garden is created by children from primary school Carolus Beaumont.
  • This garden will be both vegetable and flowers.
  • Particular attention is paid to the efficient management of water.

SOLUTIONS

Climate adaptation, resources conservation, GHG emissions

  • Implementation of bioclimatic principles in constructions (BBC Effinergie Promotelec Label and label)
  • Production of REC (installation of solar thermal panels for hot water production)
  • Support for new practices
  • Alternative stormwater management
  • Various green spaces (including a large green space of 1.8 hectares called the "Garden downwind")

Accompanying measures to change

  • monitoring of energy consumption
  • eco awareness actions in the field of energy
  • eco awareness actions in the field of waste

GC18 and the commitment of its partners to make this a neighborhood of this website development tool in line with the development of the rest of the city

Energy mix

The use of ENR in the construction program of 110 rental units

  • Installing 150 m2 of solar collectors distributed on the roofs of various buildings
  • To ensure domestic hot water (DHW) collective

The use of ENR in the building's construction program Pôle Emploi / housing for ownership (island 3)

  • Installation of solar collectors on the southern slopes of house roofs
  • Can cover around 30% consumption in Hot Water

Since the project began thinking about the energy mix

Identification by the developer and the developer of the technical and financial inability to connect on the urban network of wood heating

  • networks do not currently pass near the site
  • too long in terms of connection time
  • too expensive: financial cost generator to the financiers of the project

Identification by the developer and the developer of the non-relevance to install on the site an autonomous unit of wood heating

  • the needs are not important enough to create such a facility
  • requires to use part of the site for the equipment (processing unit and warehouse)
  • fuel supply problem in a very residential area (neighborhood nuisance problems, danger, truck rotations etc.)
  • better to use existing networks and existing sources (gas)

Total electricity needs of the project area /year

53,29 kWh

Buildings

The eco-neighborhood project includes a program to build 110 social housing under the Urban Renewal Plan of Bourges. The design of this housing also provides that the holder designated by the Office of Public Housing Cher, is particularly committed socially to respect the integration of 10% in hours of insertion. In the energy sector buildings must achieve Effinergie BBC label and get Promotelec certification.

The housing program is divided as follows:

  • 110 social housing
  • 40 needs housing
  • 19 individual housing
