Sunstone, in Meyzieu-Jonage, south-east France, will be the first positive-energy business park to be developed by Bouygues Immobilier on the outskirts of Lyon. Designed in association with architect and urban development firm Soho, Sunstone is in keeping with
Bouygues Immobilier's positive-energy Green Office® concept. This means that, in due course, Sunstone is expected to produce more energy than it will consume, thanks to its photovoltaic installations.
Spanning nearly 6 hectares, Sunstone comprises 15 buildings spread over 6 blocks. It consists of:
- 30,000 m² of office space
- a 3-star hotel with restaurant and conference rooms
- a large semi-underground car park
- a vast wooded park
Sunstone can be energy independent because it harnesses renewable energy sources. For example, the roofs incorporate photovoltaic panels producing, for the entire park, more than one megawatt per year, which offsets total site energy consumption. At the same time, heat pumps, combined with a thermo-active slab system, provide an optimum level of comfort for a minimal amount of energy consumption, in both summer and winter.
Further enhancing their energy performance, Sunstone buildings have been designed to take advantage of natural resources and limit wastefulness.
- A rainwater recovery system provides water for ground maintenance and domestic water installations.
- Effective heat insulation has been incorporated into façades and glazing.
- Solar radiation is expertly managed: in summer, the rays are confined to the outside blinds; in winter, the rays are allowed to penetrate into the open space to assist in office heating and lighting.
- Ceilings are made out of concrete, known for its thermal inertia and heating/cooling effect when used as flooring.
Moreover, to safeguard natural resources and for the comfort of inhabitants, the wood used in Sunstone's buildings is derived from replanted forests and paint and coatings do not contain solvents.
Located in a wooded park, Sunstone makes good use of its green environment. Clearings have been created in the midst of tree, grass and shrub plantations, and each block has its own garden. Thanks to its leafy surroundings, the Sunstone site does not retain heat and offers a naturally cool environment in the summer months.
