Energy-intensive building

In July 2014, SCIC HLM Gambetta and Patriarch won the competition launched by the CROUS Orléans-Tours for the realization of a residence for students of the Institute of Biomedicines and Cosmetics Bio3, on the site of the Plat d Etain in the Beaumont-Chauveau ZAC in Tours. The cost of the 9.5 million euro operation is financed by a subsidy from social rental loans of 5.5 M € and 4 M € from the investment project for the future, from the Caisse des Deposits and Consignations.The building comprises two wings of 5 floors connected at an angle of 115 degrees. The residence consists of 160 studios from 8 to 20 m², equipped with a kitchen and a bathroom. It also integrates the administrative offices of the Downtown CROUS Residence Management Service. The residence benefits from the PLS approval of the State allowing the APL to be approved for housing. The interior of the "Rabelais" residence has been carefully imagined. The functionality of the building was thought upstream and the volumes optimized, to provide a comfort of life to students. The residence also includes many services to meet the needs of student life: multimedia rooms, launderette, weight room, parking spaces and 2-wheel garages. The residence was delivered in March 2017 after 16 months of work.

Owner approach of sustainability

The objectives of the project were to design a student building with higher energy performance than the RT2012 regulation and which could have a diversified energy supply, if possible not using the wood industry.

The objectives have been met, the student residence has a wood boiler that can meet 100% of heating and domestic hot water needs. This boiler works with a natural gas backup.

The performances are reached, the RT2012 calculation figures are very favorable:

  • Bbio 53% lower than Bbio Max (bioclimatic design quality coefficient)
  • Cep 23% lower than Cep Max (Primary Energy Coefficient)

Architectural description

The building has two 5-storey wings connected at an angle of 115 degrees. The residence consists of 160 studios of 18 m², equipped with a kitchen and a bathroom. It also integrates the administrative offices of the Downtown CROUS Residence Management Service. The residence benefits from the PLS approval of the State allowing the agreement to the APL of the housing. The interior of the residence "Rabelais" has been carefully imagined. The functionality of the building was thought upstream and the volumes optimized, to provide a comfort of life to students. The residence also includes many services that meet the needs of student life: multimedia rooms, launderette, weight room, parking spaces and 2-wheel garages.

Smart Building

    KNX TP and IP, ModBus RTU. HAGER Sisto. 750 Pts of measurements, 3150 Pts GTB. Detection of lighting in the blind rooms with notification by email if in operation after 22H. Constant brightness by detection in DALI.

    Measurement of student housing and commons consumption with Hager Energy.
    Three electrical domains are measured per housing via induction toruses (IT).

    Lighting management
    - In case of detection, the lighting switches on and regulates on a pre-defined threshold at the GTB. The default threshold is 350 Lux.
    - At the end of the detection, the lighting goes off after 5 min. The room returns to automatic mode if the manual mode was engaged.

    Monitoring of blind parts
    All blind parts (attics, bookshelves, workshop ...) with a traditional ignition have a KNX input to know and visualize the state of lighting on the GTB.
    GTB can not act on these lights.
    In case of ON state after a certain time (Ex: 22H), an email is sent to the site manager and archived in the tracking file.

    Central extinguishment
    A button allows the general extinction of all rooms whose lighting is controllable. This button has no influence on the blind premises.

    Heating regulation
    Some rooms (offices, workroom) have an individual KNX controlled regulation, provided by a control thermostat TX410 associated with one or more TX501 valves.

    No management performed by the GTC for domestic hot water and air handling unit.

    Management / Facility management

    The infrastructure used as the basis of the system ensures the scalability of the hager-energy solution. Based on the KNX protocol, it allows the addition of functions over time such as heating management, centralization of shutters and still lighting. A building equipped with hager-energy can therefore offer à la carte services, depending on the needs and budget of the occupants.
