    Energy-intensive building

    RT2012-30% for geothermal probes offices

    Called "The Butterfly" because of its shape, the building is adorned with colored frames tart berries in green and yellow tones. It has about 13,500 m² of floor space spread over 7 floors and comprises just over 600 employees in the County Council Seine-Saint-Denis since its delivery early 2015. Last lot ZAC Jean Rostand in Bobigny in Seine-Saint- Denis, Le Papillon is certified HQE passport Excellent level and reaches energy consumption levels RT2012-30%. Its design was very thoughtful upstream in a logic of passive efficiency, enabling the realization of a virtuous building envelope favoring the efficient and innovative technical features in an easy-care and operating at low loads. In addition, 80% of 99% in hot and cold requirements needs are covered so unlimited through geothermal probes coupled to a heat pump. Exemplary in its design and in its ecological footprint, The Butterfly was supported by ADEME.

    Sustainable development approach of the project owner

    The Papillon is a continuation of a systematic and sustainable approach Sodéarif SEQUANO and Development in achieving virtuous operation. Since the delivery of the headquarters of Bouygues SA in 2006, the first office building delivered in Paris who received HEQ certification - Commercial Building, Sodéarif continued its development by making its commitment to sustainable building design a trademark. Sodéarif has seen particularly recognized for its commitment with the Australia building in Montigny-le-Bretonneux, which was awarded the Trophy Constructeo 2010 at the SIMI (the Commercial Property Exposition) which rewards the most efficient building of the year in energy and environmental plan. Le Papillon for the building, the objective was to achieve an economical building at RT2012-30%, particularly inexpensive to use by the introduction of geothermal probes providing hot and cold in the building. The aim was also to demonstrate that achieving these environmental objectives is possible in compliance with a neat architecture and qualitative, to Parisian standards, in a mastered project economics.

    More information

    All positions consumption object is made an estimate in design in order to optimize the overall energy performance of the work. The project will be an energy monitoring over 2 years in order to support the operator in the building grip and sustain energy performance. This monitoring will also compare the actual consumption with the estimated consumption design.

      • Heating and cooling by a geothermal heat pump to dry probes. 36 100m depth probes under the influence of the building. The heat pump enables 80% coverage of hot needs and 99% of cooling needs, the extra is by gas boilers. The hot water is by electric balloons decentralized, more efficient than centralized production given the low puisages (avoids the loopback losses). The heat pump works with an average COP of 3.7. Issuance by heating low-energy fan coil units. The local refresh is provided by the "free cooling" through the cooling capacity of the soil. Performing double flow ventilation (75% heat recovery).

    Smart Building

      Centralized management of external directional breezes sun, lighting management by dimming at the loan needed, the installed power has been optimized (4W / m² for a level of 300 Lux).

    Biodiversity approach

      Inaugurated in April 2015, the office building "Papillon" is the last operation of the ZAC Jean Rostand in Bobigny initiated in 2000. The operation is located in Bobigny in the ZAC Jean Rostand on the last available block (Block 2) . It is served by tram with a stop right in front of the site (T1 | stop Jean Rostand) and the subway to 400 m (L5 | Stop Bobigny - Pablo Picasso). Located at the intersection of major infrastructure as the A86 motorway and tram T1, near recent commercial buildings, multi-family buildings and in the vicinity of an area of ​​suburban homes, its urban context is particularly composite . "The Butterfly" is the final piece of an urban and programmatic puzzle, it must both be required to be identified and integrated into that "already there" frame.

    Reasons for participating in the competition(s)

    Vertueux à tout point de vue, Le Papillon tire ses qualités :
    • d'une conception passive, bioclimatique, orientée sur l'efficacité de son enveloppe (isolation renforcée, protections solaires extérieures pilotées, étanchéité à l'air soignée) ;
    • d'une ensemble de sondes géothermiques couplées à une pompe à chaleur assurant 80% du chaud et 99% du froid par la capacité calorifique du sol ;
    • d'une VMC double flux performante assurant la récupération de plus de 75% de la chaleur de l'air renouvelé ;
    • de matériaux à faibles émission en COV (composés organiques volatils) grâce à l'utilisation de matériaux étiquetés A minimum et A+ à 80% pour les revêtements intérieurs, garantissant ainsi la meilleure qualité pour l'air intérieur ;
    • de revêtements de sols bio-sourcés ;
    • d'une certification par CERTIVEA : HQE passeport niveau Excellent et 6 cibles Très Performantes.

    Ces 6 cibles Très Performantes sont :

    • Cible 3 - Chantier à faible impact environnemental : plus de 90% des déchets de chantiers valorisés dont 80% sous forme de valorisation matière ;
    • Cible 4 - Gestion de l'énergie ;
    • Cible 7 - Maintenance : accompagnement par un spécialiste en phase conception a permis de mieux intégrer les problématiques d'entretien et d'accessibilité aux équipements ;
    • Cible 8 - Confort hygrothermique : protection solaires extérieures, travail sur les surfaces vitrées permettant une gestion optimale des surchauffes ;
    • Cibles 11 et 13 - Qualité de l'air: haut niveau de filtration de l'air neuf et matériaux à très faibles émission de COV.

    Enfin, pendant 2 ans, Le Papillon fera l'objet d'un suivi énergétique spécifique afin de former et d'accompagner l'exploitant dans la prise en main du bâtiment et de lui permettre ainsi de tirer au mieux profit de ses atouts, dans une logique de maitrise des charges d'exploitation et d'entretien.
