Energy-intensive building

Schneider Electric Horizon: actual energy performance, engaging, durable and guaranteed by contract of 40 kWh / m2/year final energy outside solar production!

The production of photovoltaic energy (220 GW) is equivalent to the energy needs of the building.

Built as part of a merger of Schneider Electric sites involving R & D and production, Horizon site is from a co-design involving the company and its staff, the architect and the builder. This building serving quality of life at work, is BBC certified by Certivéa.

The project summary:

  • 3 floors of laboratories and offices for R & D(5436 m² SHON).
  • Capacity: 350 people.
  • 8 million euros overall budget, including photovoltaic.
  • A design that minimizes environmental impacts and optimizes the geographical context.
  • An exemplary building in terms of energy efficiency, which triggered a contract of "guaranteed results" with the constructor: 40kWh/m2/year in final energy outside solar output and continuous onitoring of performance levels.

SUB Award 2013 - this building contributes to "the city of the future":
As an exemplary building in energy efficiency, "Horizon" and its 40 kWh/m2/year meets the requirements of smart and connected buildings of tomorrow.

Sustainable development approach of the project owner

At the beginning of the 2000ies, just like every contractors, we looked into what a « smart » building really was, or rather what the market meant by “smart”.
Today, with « Horizon » we have an actual answer to that question as well as a tool for continuous improvement for
• energy efficiency,
• comfort and service towards our users,
• respect of the environement,
• our assets
• and control of our management costs.

For each of those expected performances, constant attention and mutual respect were the key factors for the success, in our work-groups « users-architect-experts-constructor » for optimum and global efficiency.
By cultivalting attention and co-design, we benefitted from the best feedback, especially from the users, who became actors of the energy efficiency, thanks to our Building Management System tools.
Through this model project, our site of Carros becomes our greates t satisfaction, not only as a display for energy efficiency, but also as an actual proof that choosing partners for their expertise and excellency we can respond to the highest demands in terms of comfort and respect fo the environment.

Architectural description

Located along the highway feeder and the Var, the project fits harmoniously into the existing industrial zone.
Its position, height and architectural treatment, both sober and urban, requalify the whole Schneider Electric local complex while creating a strong architectural signal at the roundabout.

The continuous frontage on the avenue is divided into three levels, punctuated by colorful perforated metal partition panels. Meant for aesthetic and sun breaking functions, these panels also provide protection against intrusions when the chassis will be open at night to cool down the building naturally. Open spaces naturally benefit from the orientation with a view on the "large landscape" which enhances the quality of use of workspaces.

The inner western façade organizes the main flows of each level. It is protected from solar radiation by a double skin stainless steel mesh and a photovoltaic roof overhang.

The connecting building link the old and new buildings together, upgrades the entrance to the site by its elegant architecture of stone, metal, glass and plants.

The lightness of treatment between the two constructions leads to the possibility to differentiate in terms OF uses and users over time. Finally, a curved roof with photovoltaic panels illustrates the fifth facade and fits perfectly into the surrounding hillside reliefs.

Building users opinion

A recent survey of residents indicates a high level of satisfaction.
Fruits of attention, tertiary spaces have an excellent level of comfort and a remarkable energy balance because of the architecture and technical solutions:
- Comfortable light thanks to large windows, various sunscreens that maximize the flow of light and light sensors and presence for artificial lighting.
- Acoustic comfort and thermal double glazing windows (Ug 1.1 W/m2 / ° C), the acoustic ceiling (> 40 dBA), soils in carpet tiles (LW> 31dBA) and modular partitions of windows offices that provide a very good sound attenuation (> 35dBA)
- Ease of use due to self-management system of the building that allows the user to control itself (an area of ​​50m2 open space or private office or meeting room).
- Lighting
- Sunscreens
- Heating and air conditioning

If you had to do it again?

The whole program would be redone in the same way: the project is extremely smooth, and the new building was a key asset in the management of change that was taking place at this moment in the company.

    • Located on the roundabout to access the business area of Carros, the new building of Schneider Electric sign the new face of the ZI.
    The location of the building N / S along the public road serving the area Carros and along the banks of the river Var was a deliberate decision to give a double response "energy" and "image".
    The building develops on public space (roundabout and access road), an urban façade flanking 3 levels punctuated by colorful cages sunscreen.
    Is located on the front of all open spaces.
    Tertiary plateaus overlooking the front have a soft light and a view Is so-called "large landscape" offered by the Var valley.
    Service to the business area of ​​Carros was valued by road improvements, the tram network and a pole multimodal exchange. More than 20 km from Nice, Carros has the second French International Airport.

    Management / Facility management

    You follow in real time the energy consumption of your building, you identify underperformances, you check, with just a click, the effectiveness of your action plans.
    You communicate with your employees and promote the adoption of best practices. Thanks to the energy management software, you can control your CO2 emissions.

    Restitution of energy performance information to users accentuates their position as actors in energy efficiency.

    Chilled beam scattering by a CTA based on pressure / volume makes a fresh atmosphere in the cooling mode and prevents the effect of cold mouth. It thus contributes to the comfort of users workspaces

    Sunscreens

    In heavily exposed to solar radiation area, insulation is key for the thermal equilibrium of the building. These protections are established:
    - A passive external insulation 20cm
    - A canvas stretched steel high pressure levels L1 L2 of the west facade
    - Shading of the ground floor of the west facade and the south gable driven GTC
    - Blinds textile facades is controlled by GTC
    - The photovoltaic roof with a large hat on the west façade to optimize production and protection when the sun is at its zenith

    The orientation of the building is a compromise between photovoltaic and thermal impacts minimization south gable. Sunscreens also affected the organization of space as the west façade does not fully protected type light first day and therefore corridor lies to the west, the workspaces are located on the front which is' is exposed to radiation in the morning (protections textile blinds.
