Energy-intensive building

Max Weber Building is a pioneer building that reviews in depth the standards of the office building, and uses environmental requirements as a motor of innovation and architectural design. Its 5 levels are 100% wooden structure, including elevator shafts and stairways, while the office space - Flexible and scalable - are free of false ceilings and raised floors false. This passive building without air conditioning, is naturally ventilated through an architectural device that manifests roof by 25 ventilation stacks of 3.70 meters high.

Sustainable development approach of the project owner

The University of Nanterre wanted to incorporate a High Environmental Quality for all of its operations on campus. This should incorporate the requirements of the master plan of the campus and the climate plan of the city of Nanterre. He was asked the project management team to integrate this approach to environmental quality early in the design phase and reasoning about the full life of the building (production / use and exploitation / deconstruction).

Targeted HQE targets are:

3 Targeted levels: Base (B) High Performance (P), Very High Performance (HP)

ECO BUILDING
01 "harmonious relationship with the immediate environment" HP
02 "Integrated choice of products, systems and construction processes": P
03 'Chantier low nuisance "HP

ECO MANAGEMENT
04 "Energy Management": P
05 "Water Management": P
06 "Waste management activities": B
07 "Maintenance - Sustainability of environmental performance": P

COMFORT
08 'Hygrothermal comfort ": P
09 "Acoustic comfort": P
10 "Visual comfort": B
11 "Olfactory comfort": B

HEALTH
12 "sanitary quality of spaces": B
13 "Health Air Quality": P
14 "Water Quality": B

The environmental approach of the client was ambitious and project management went beyond that demand, particularly on the target 2 (integrated choice of products ...), No. 4 (power management ), No. 7 (maintenance, sustainability ...), No. 10 (visual comfort) and No. 12.

Architectural description

A strong environmental ambition presided over the design of Max Weber building. It helped re-examine in depth the nature of the office space available to researchers and propose new architectural tracks.
Office buildings are indeed too often ultra standardized products that often find their identity in a formal bidding at the façades and decoration.

Max Weber building was designed to avoid, thanks to a strong environmental ambitions, the trivialization of workspaces for researchers. This is indeed an atypical building, completely wooden, passive, and with natural ventilation in winter and summer. The materials used are used where they are most adapted and appear as what in the truth of their joints. For this, the false ceilings and air conditioning were banned from offices and controlled mechanical ventilation. Contrary to common practice, the structure is not concrete but entirely of wood, which visible, highly branded interior spaces and gives them a unique and warm character. The hallways are not blind but enlightened course and views to the outside. The three cages of wooden stairs also bathe in natural light with wide views.

Large office windows consist of two opening, allowing occupants to customize the management of their atmosphere.
The floors raw concrete, covered with linoleum, contribute to the inertia and summer comfort in the premises without the need to use an air conditioner.

To achieve this, the problems related to acoustics and integration of networks have thus been designed in a different logic, very early, at the architectural competition, along with the project structure and organization of spaces.

Retaining the architectural style fits in harmony with the existing buildings, and is distinguished by a simple volume, slightly cut the corners gentle terraces and outdoor spaces in piles. Its aluminum siding hints from the outside, thanks to generous openings regularly arranged, the strong presence of wood in the interior spaces, while large chimneys on the roof signal a singular ventilation.
 
Here, the architectural expression of the building is marked by the contrast between gloss and smoothness of the outer skin of aluminum and matte nature, organic and warm wood used for interior spaces.

Building users opinion

Returns from the Head of the University's heritage: it speaks of a building seductive effect with its users. People completely appropriate the building and say hello to each other! The stairs are a real architectural object that impresses.

    • Following the request of the project ownership, a volume of 20m3 recovery of surface water is intended for watering green spaces. These needs over a period of 6 months, the mastery of work proposed to connect the tank to the health of so to cover these needs by building unsafe water when there is no need for watering.The study shows that the 20m3 storage tank allows, if it is connected all year on the toilet, to cover 34% of health needs to be an annual saving of drinking water 315m3.

Reasons for participating in the competition(s)

Une structure 100% bois y compris cages d'ascenseurs et d'escaliers- des plafonds de bureaux en bois massif, sans faux plafonds- un bâtiment de type passif équipé d'un dispositif de ventilation naturelle assistée- un bâtiment non climatisé- un bâtiment modulaire, flexible et évolutif​- lumière naturelle dans l'ensemble des circulations : couloirs, cages d'escaliers...
le choix du bois répond à des considérations écologiques. Le bois est en effet un matériau biosourcé, renouvelable, recyclable, qui absorbe du carbone au cours de sa vie et le stocke dans la construction.
