Envelope performance

• Envelope U-Value : 0,50 W.m^-2.K^-1
More information :

Insulation from the outside. The glazed walls were studied specifically both their proportion in facade, and the characteristics of the glazings. The characteristics selected are the following:
- Double anti-emissive glazing with argon blade of Ug ≤ 1.1 W / m².K
- Low solar factor: FS ≤ 28%
- High light transmission: TL ≥ 60%
Thermal bridges are reduced to a minimum; this will be achieved by continuous insulation of the envelope, interrupted only in a few unavoidable places, in particular the crossings of the envelope by structural elements. Adequate solar protection will optimize the thermal behavior of the building during the summer period.

Indicator : I4

• Air Tightness Value : 1,20

Users' control system opinion :

Control of the offices in winter provided by radiant radiators General instructions imposed by GTB, with adjustment to +/- 3 degrees achievable by the collaborator The luminaries implemented in the entire project are LED type performance with modulated lighting depending on the ambient illumination on the two rows closest to the facade; Regulatory programs for CTA systems.

A field of photovoltaic solar panels covers the roof of the project as well as the parking lot. This renewable electricity production aims to offset the consumption of heating, domestic hot water, cooling, auxiliary and lighting stations, in accordance with the requirements of the BEPOS label. The total area of ​​solar panels is around 1,500 m², divided between the roof of the L6 and the coverage of parking spaces.
Use of a Canadian well to pre-cool or pre-heat incoming air;
Recovery of calories extracted by the CTA for reinjection into the building (wheel exchanger with very high energy performance);
Heating ensures by the heat network of the municipality of geothermal origin;
Pooling with building L4 of cold production;
Cold group with water condensation with double compression stage for the valuation of calorie releases towards the Heat Network (donation of colors to the network).

Urban environment

• Land plot area : 70 000,00 m²
• Green space : 25 000,00

This new building is part of an urban renewal project for old scrap yards (2ha, total site 7ha). The first building built in 2014, and the latter, the L6 in 2018, were designed integrating a flourishing biodiversity where landscapers, cosmetic gardens and filter basins came to improve the frame of view of employees. This project was awarded in 2015 by ADEME by the Business & Environment Grand Prize in the Biodiversity category. The construction of this new project was evaluated during the experiment for the HQE Biodiversité in 2015, where an increase of the diversity of the environments and the permeability of the grounds had been welcomed. It is juxtaposed with the departmental green flow and a work was done with the landscape architect to include it by the urban landscape. A partnership with the city of Chevilly-Larue has made it possible to create a fresco for sustainable development in order to sensitize our fellow citizens to this theme of the future. The site and the L6 are accessible via the metro line 7 and the Tram T7 reaching the airport Orly. The site has surrendered part of its land to accommodate this important means of transport for so-called "soft" urban travel. A study of all flows in-house was conducted to better anticipate needs (pedestrians, bicycles, vehicles waste, logistics, waste).

Unused building but feedback from the building next door built in 2014: 50% of sanitary needs will be provided by rainwater.
New features on this building: injection of process water lost in the sanitary water tank + work with the ARS to reuse treated wastewater in addition and reach 100% of non-potable water for sanitary facilities (experimentation following the PA France Experimentation)

Indoor Air quality

Air quality provided by:

- efficient ventilation adapted to occupancy and preventing the transfer of air from polluted premises to sensitive premises (30 m³ / h / person in the majority of occupied spaces);

- control of pollution sources with the implementation of materials compatible with their use, representing qualities in terms of robustness and ease of maintenance, but also in terms of intrinsic health quality of materials and construction products. The choice of these materials (floor coverings, walls, and ceilings) respects the classifications corresponding to the A + labeling characterizing their emissions: TVOC: Class A + (or <1000 μg / m3) & Formaldehyde: Class A + (or <10 μg / m3).

Comfort

Health & comfort :

Visual comfort: in the design of the visual ambiances, the objective was to facilitate and make pleasant the activity of each one, by providing comfortable and controlled environments at the workplace, with:

- Natural lighting: All rooms where natural lighting is required have large windows, with a maximum height under the lintel. As far as functional requirements permit, extended-use spaces provide occupants with visual contact with the outdoors and direct views of the building surroundings. FLJ is greater than 0.7% over the entire area of ​​the first rank zone; light transmittance of glazing: 60%. Particular attention has been paid to direct solar radiation, which can cause glare effects in addition to its thermal effects. Glare due to natural lighting is avoided by the radiation-controlled exterior blinds and the indoor screen blinds.

- Artificial lighting: The luminaires are LED type performance. The color rendering index (CRI) will be greater than 85% and the color temperature of the order of 3500 ° K - 4000 ° K. To avoid glare, the luminaires used are low luminance (UGR less than 19 or 22 depending on the premises). Whenever possible, a combination of soft general mood lighting and accent lighting on the workspace is preferred.

The articulation between natural lighting and artificial lighting is a key to the comfort and environmental economics of the project. To avoid areas of excessive illumination, artificial lighting is flexible depending on the ambient level near the facade, with possibility of servocontrol. Wherever an automatic modulation of lighting is envisaged, the users always have the possibility of intervening to modify the level of the lighting. The lighting is modulated according to the ambient illumination on the two rows closest to the facade.

Sanitary quality of the water: Domestic hot water networks are maintained at 55 ° C minimum. Legionnaire's disease will thus be discarded with storage at 60 ° C. The distribution networks are closed, without any dead arms. The temperature probes on the hot water network will be connected to GTB.

Electromagnetic Exposure Limitation: The main sources of low frequency emissions are transformers and high voltage overhead lines lining the ground to the south. The building's layout respects the regulatory safety distances. All equipment, equipment and other laboratory equipment provided for in the project comply with French and European standards for electromagnetic fields. Grounding of the switchgear meets safety standards.

Acoustic comfort :

Acoustics worked with acoustic carpet under ceiling as well as acoustic panels between the offices of the collaborators.
