Energy-intensive building

Sustainable development approach of the project owner

The activity generator is a manifest building, with positive energy. It is designed to minimize energy consumption in order to consume less energy than it produces. Made from materials with low energy and carbon footprint, it has the double certification NF HQE ™ Tertiary Buildings - New or Renovation and BREEAM (Anglo-Saxon equivalent of the HQE certification).

Architectural description

The building is articulated around a large atrium intended to promote exchanges. With the other common areas, this part represents almost half of the building. The rest is divided between office areas, modular and configurable offices or meeting rooms, a large technical hall: it is, in fact, a large hall that is cut in three. Attached to this hall, a 3D printing room surmounted by an open-space office. Under the office area, on the ground floor, a parking space (bicycles and vehicles) ensures a reserve of space to increase office space. The building design also allows for the expansion of the 3D printing room and technical rooms. In total, the extension can reach 500 m².

The equipment:

  • Individual and collective office spaces
  • Coworking spaces
  • An industrial technical hall of 340m²
  • A 3D prototyping hall
  • Experimentation platforms
  • Shared services and equipment

Dedicated spaces of conviviality The architecture of the generator is subtly unveiled with the aim of creating, in the heart of the effervescence of the city of Anglet, a privileged and calm living environment, a way of living this location. The boundaries between the outside and the inside are intentionally blurred to take advantage of the vitality of the environment, with the aim of integrating in the heart of the building the presence of natural light and its variations. In the West in urban catchment, the hall of experimentation is exposed in panorama on the street Mirambeau, by a big horizontal incise, like a signal announcing the research and development works hosted in the Generator. To the east, echoing the landscape of the Estey, the facade of offices opens generously to nature. External running corridors allow to take advantage of the softness of the site and favor the informal meetings by prolonging outside the workspaces.At the heart of the Generator, the bioclimatic atrium unites these workspaces as an open forum for debating ideas. It also brings together the vertical and horizontal circulations treated in rhythmic routes, revealing the activities, allowing to take advantage of the natural light and offering framing on the raised landscapes. Everyone is no longer the inhabitant of a floor, an office, but a workplace in which knowledge, tools, dedicated spaces and services are pooled. Scalable, the building is designed to shape, adapt to demand, suspended from future societal, technical and energy developments. Based on the structure as a pivot, the envelope is an interchangeable and recyclable skin. The interior is made flexible and reversible, it remains ductile uses. The Generator will live to the tempo of the young companies that will invest, take ownership and evolve.

Building users opinion

The 3 oldest tenants were the subject of a satisfaction survey (30 questions) and the points of dissatisfaction were the subject of corrective actions: repair of blinds (in progress), balancing ventilation networks, recovery of the ECS in the locker room.

    • A bioclimatic passive building
    Natural means are favored over technical means to ensure thermal comfort, natural lighting and air quality. The building is not mechanically refreshed, only passive ventilation ensures summer comfort. For that, the constraints and the assets of the site were taken into account from the beginning of the design. The building is divided into three main entities: the heated offices, the regulating bioclimatic atrium and the tempered and unheated technical hall.

    Limit wastage
    The building, of the passive type, is adorned in the first place with efficient insulation and optimizes solar and luminous gains. The static losses of the building are thus limited by this insulation and a strong requirement on thermal bridges and airtightness.

    A powerful energy design
    The emission of heat in offices is simple, economic and sustainable: fan coil units with heat generation by air / water heat pump that is adapted to the Anglet climate because it has very good COP (Coefficients de Performance) for mild temperatures.

    A building in self-consumption
    The CAP, as well as the rest of the equipment, is directly related to the photovoltaic production of the building
    to achieve the goal of self-consumption but also to limit the consumption of the building from a regulatory point of view.

    Passive ventilation
    The entire building is treated by passive ventilation by the installation of opening in transom both on the exterior facades and on the interior walls in contact with the central atrium. The regulatory air change of the premises is carried out by a dual flow CTA with energy recuperator.

    190 m² of photovoltaic panels on the roof: peak power: 12.7 kWp - 44 cells
    3 solar chimneys on the roof.
    Photovoltaic production: 105.10 kwhep / m².year

Urban environment

    The Arkinova Activity Generator is located in the heart of the town of Anglet in the department of Pyrénées-Atlantiques, an area classified as seismic level 2 since 2010. Located north of the slopes of the airport Bayonne-Anglet-Biarritz, the parcel, a former dump, is an urban wasteland on the edge of a protected wood and estey. The Activity Builder project is the first structuring element of the Arkinova Technopolitan Campus. This campus is a vast landscaped area of ​​49 hectares, in the heart of a metropolitan area undergoing major urban changes. To date, it brings together local eco-construction companies, an ISA BTP engineering school, the journeymen training center, the University of Pau and the Adour countries and its research laboratories as well as a vocational high school with a specialization in the field of construction. The aim is to develop synergy and collaborative work between companies and higher education. The plot leans against a wooded relief to the South and overlooks the estey to the east marked by the presence of an old watercress reconquered by a moist forest afforestation. The terrain has a steep slope from Mirambeau Street in the west to the downstream estey.
