Sustainable development approach of the project owner
Integrate sustainable development approach on this building by incorporating key environmental themes (energy, biodiversity, mobility, quality and comfort of indoor environments).Support users during the works (works on an occupied site) and after the work on energy efficiency.
Architectural description
Building renovation without altering the architectural, putting up to date some facadesBuilding users opinion
Good accompaniment when working with large display and communication on the progress of work. Surveys of employees during and after construction. Perception some noise on some workstations
General sense of pride about the nature of the work and ongoing renovation.

A layer of metallic microparticles invisible to the naked eye is deposited on the inner surface of the glass and serves as low-temperature heating resistor (20 to 45 ° C) allowing:
- To eliminate the feeling of cold walls
- To have only one side of the heating pane (the other part of the glazing, outside stays cool).
It's nice not to feel the effect of cold walls: these are the surfaces poorly insulated a building, responsible for a cold radiation, heat loss and discomfort.

Creating an air current between the opening of the window of the inclined curtain wall and a hole in the roof that extends through a steel tube, painted black.Natural convection movement created and amplified by the introduction of year-end aspirotor fireplace that rotates with the wind and / or air movement.
The solar chimney is an innovative, simple, efficient, sensible and perfectly suited to our building.

Autopilot energy efficiency, it allows a daily and automatic optimization of equipment. The comfort level returned by the user on a web platform. The tool then manages the technical equipment to achieve this comfort, taking into account the actual and future weather conditions, the properties of buildings (permanently performed dynamic thermal simulation); to start the operation of equipment to the optimum.
Effipilot is a friendly and easy to handle tool.
