Energy-intensive building

This school group comes from a Concentrated Pedagogic Group (RPC). It includes 12 classes and a multi-home center, in MH perimeter.

It is part of a sustainable development approach and is exemplary. For this, a positive energy project (BEPOS) has been developed. The child, at the center of the concerns, dictated the layout of the spaces and their ambiances. The project represents a symbol of modernity, sustainability and educational and cultural openness.

The building takes the form of a ribbon walk-in, which marries the uneven ground. The roofs are vegetated to integrate the project into the landscape and create a "fifth facade" in the extension of the meadow. This bias allows a harmonious cohabitation with the neighboring Château du Cauroy. The facades are adorned with light-colored bricks and wood. In order to achieve the BEPOS performance, a wood boiler, a wooden silo and photovoltaic solar panels are installed on the operation.

Sustainable development approach of the project owner

The constuction manager follows a sustainable development approach - HQE program without certification.

The focus has been on: Sustainability, maintenance, maintenance and operating costs. The program has induced a bioclimatic architecture relayed by major technical equipment: wood boiler, wood silo and photovoltaic solar panels. The wish of construction manager has been to achieve an exemplary building.

Architectural description

The architecture of our building marries the plot and plays with differences in the level of the ground to minimize its impact in the site from the departmental road. The development of the planted alley leading to the castle is thus preserved while signifying the project since the hamlet. In this way, architectural devices allow to collect and ensure differences in soft levels and conducive to sensory and motor experiences.

Open to the outside, these transitions held and varied frame the landscape, punctuate the course and open the culture to nature.

The project therefore aims to assert its status of intercommunal equipment at the scale of the territory while ensuring a harmonious integration into the local landscape, concerned about the built and plant heritage that surrounds it.

The project is composed of three large entities (a kindergarten, an elementary school and a multi-home), it is necessary to make them clearly legible from the public space, as well in their functioning as in the links which they maintain between them .

This translates into their clear positions in the overall device. Located in the direction of the slope, the two schools are juxtaposed in the wings North and South while the multi reception and the restoration are signified on the service.

If you had to do it again?

The undersides in steel tray would have required a special finish so that the fastening screws are not visible. However, all the actors of the project had a decisive role in the realization of the operation. It is with enthusiasm that we would take part again in the experiment.

Systems

Smart Building

    The installation is equipped with an integrated web server which allows access, via a simple web browser, to all the information of the installation. The exploitation, but also the setting up are carried out online, from simple HTML pages, without downloading of a software of exploitation on the computer station:
    - remotely, in ADSL or RTC,
    - locally, via the RJ45 connection of the Ethernet port.

    Alarms are broadcast periodically and / or on a change of state via several media (PSTN, ADSL, GSM, Ethernet).
    Alarms can be sent via e-mail to a monitoring or supervisory PC, or via SMS (with the optional GSM extension) on a mobile phone depending on each user's on-call schedule.
    Depending on the level of access of the user, directly online via a web browser, it is possible to act as a remote control and remote control to change the values of the data and control live installation (rescue actions, interactivity, taking in hand fast ...).
    The installation allows the simultaneous connection of several users locally and / or remotely, the management of their directory and access rights to the various functions. Four levels of access to functions can be defined and the display and control of data can be customized for each user. Its compatibility with the Modbus protocol (series or tcp), the opening of its protocol to the world of supervision, its link with access control systems, electrical meters allow the system to overcome the communication barriers and become the best unifying element of the installation.
    The instantaneous values of the site can be consulted at any time. Remote control or remote control can be operated remotely on this data. For this, the installation provides several tools:
    The states display the values of the installation in the form of a list and animated symbols and make it possible to act as remote control or remote control on these points. The user can select the displays and view all site data in a fast and user-friendly way.
    -The Synoptics offer a simple navigation and allow to visualize the whole site, at a glance. They are easily built thanks to a library of objects provided and the ability to download its own images.
    Thanks to its large storage capacity, the installation offers several types of history:
    Alarms and timestamped events are archived and accessed from the Event Log. The Outstanding Journal displays the alarms still present on the site.
    -The data is plotted and rendered in the form of curves, viewable from the graphs (exportable in Excel format).
    Each screen is printable and can be archived in different formats, the installation also allows to export the raw data in Excel format for more elaborate mathematical treatments. Regularly, the user can publish a complete report of the exploitation of the site, or to receive it by e-mail in an automated way
    It is possible to organize the "remote diagnosis" of equipment by setting up preventive alarms (monitoring the number of faults, operating times, etc.), by taking control very quickly, remotely, without specific software, and thus avoiding costs. shutdown.
    In addition, the installation offers a maintenance aid thanks to its ability to integrate in its ftp server the documentation files of the various equipment of the installation.
    The installation, from option +, integrates a script generator which allows to program its own automatisms in advanced language. Without compilation, online and with a simple browser, it is possible to set up powerful automation functions and change the installation: automatic reaction and security, interactivity between data, customization of chain actions ...

    Local production of energy by photovoltaic solar panels (288) installed on the roof with a total power of 86.4 KWc and an annual production of 75554 kWh. Energy not consumed by the building is reinjected into the network (resale).

    • Located on a hilly meadow, bordered by a majestic alignment of plane trees, the pole of education and leisure takes its place below the street of the Platanes and turns towards the hamlet which borders the castle of Cauroy. Implanted in the direction of the slope the two schools are juxtaposed in the wings North and South while the multi-reception and the restoration are signified on the service.

    A common forecourt serves the three entrances.

    Parking is arranged along the street of Platanes
