Introduction
French National Eco-Quartier Grand Prix 2009 for the «High Environmental Quality» (HQE)
conversion of the old Bonne garrison in Grenoble
The city of Grenoble and the Ministry of Defence launched in 2000 a programme for the conversion and development of the old Bonne garrison, located between the city centre and the
«Grands Boulevards».
The project proposes new housing quarters (family and social housing), a park and a shopping
centre as an attractive destination for the newly extended city centre.
In 2005, Groupe-6 won the competition for the design and construction of 16 643 m² of shopping space, which should open to the public in 2010.
Two objectives in one: expand the city centre of Grenoble through a sustainable and responsible
urban redevelopment.
The « caserne de Bonne» site was sold to the city in 1990 in order to develop a model green
ZAC (concerted development urban area), with high environmental quality (HQE). The project is
partialy funded by the European program Concerto (which has already sponsored 45 communities in 18 countries in Europe). This European Commission initiative is working to deliver the
highest possible level of self-supply energy. De Bonne is commited to respond to these future
challenges.
The Caserne de Bonne project was awarded on the 4th of November 2009 the French National Eco-City Grand Prix by the French Ministry of Ecology.
With its 8,5 acres, the project will transform a military fortress into a new quarter - dynamic,
radiant and open to the city.

An open promenade
towards the city
Off the beaten tracks, a commercial centre like a city quarter
The multifunctional commercial centre of the «ZAC de Bonne» is composed, from East to West,
of 5 buildings and an underground carpark of 355 parking spaces open 24 hours :
n the «East» building with its main 1st and 2nd levels dedicated to shopping; while the 3rd floor
will host offices
n the main level of the old garrison’s northern wing will accomodate several boutiques and a
restaurant
n the «North» building, next to the old garrison, will contain shops on the street level and 1st
floor, while the 2nd floor will be dedicated to office spaces
n the covered hall «Halle» is a longitudinal mall on 2 floors only
n within the same building : the student’s accomodation hall, and a commercial space dedicated to a future Monoprix on the street level, first and the second basement
Embrassing the ZAC sustainable regeneration, the centre is designed like a green city quarter.
From the material used, the parking, the terrasses by the park, the covered and uncovered
streets and squares, the service, to the bioclimatic mechanism, everything belongs together.
The mall is a green, fresh and welcoming luminous volume permanently connected to the park
and the street. Large glass vitrines, places and restaurant terraces extend these open views
while the timber louvers and glass roofs let the natural light infiltrate this shopping promenade.
More than a commercial space, the «Caserne» is a place.

A sustainable and
energy efficient centre
Recyclable materials and bioclimatic system for the first High Environmental Quality (HQE)
commercial centre in France
To deliver a truly sustainable project, it is essential to meet the «triple bottom line» of environmental, social and economic considerations. Clients need a partner who can navigate them
through the wide array of choices available and push the boundaries of current practice. Good
sustainable design comes from utilising a site’s natural properties and involving engineers early
in the design process. Moreover, sustainability is closely linked to longevity. Cleary, given the resources invested in a building, the longer that this building remains fit l for its purpose the greater
the time before an equivalent amount of resources will be spent on its replacement.
As an «eco-quarter» or sustainable quarter, the «Caserne de Bonne» project is dedicated to reduce its impact onto the natural environment, boost economic development and quality of life.
Beacon of the HQE objectives for a commercial centre, the project has to comply with a series
of criterias for its conception - choice of materials and energy providers; and its performance
(subject in fine to its users) :
n Choice of a wooden structure for the «Halle», while concrete is used for the superstructure
only. The architects have used European tree species only (from France and Austria). This is the
first commercial centre of this kind in France
n The «Halle» is covered by 1000 m² of solar panels
n From the start, the project has opted for a bioclimatic system and the use of collectively
generated power :
- Heat is produced thanks to the urban heating system («chauffage urbain»), a network heating system allowing a minimum rejection of CO2 (objective of 161g/kwh produced)
- The «Halle» itself is naturally ventilated - no heating, no air-conditionning. Its external façades
are well insulated while its internal enveloppe encourages thermal exchanges with the shops.
South oriented, it is closed in winter, heated by the sun. In summertime, the doors open allowing
natural ventilation. This bioclimatic micro-climate reduces the needs for air renewal and cuts
heat losses
n The air-conditionning system for the rest of the buildings works with the ground water
(between 13 and 15 °C)
n Half of the pluvial rains are absorbed thanks to an infiltration trench, and the rain drops are
regulated thanks to the green roofs (holding of 55mm of water, i.e. 68% of the decennial rains,
i.e. 80mm over 24h)
