Aile 1000

how to make the administrative heart of a hospital beat to the rhythm of its three levels & its atrium

project characteristics

The building consists of 3 floor levels & is located on a semi-buried car park. The ground floor plan is structured around a “heart”: the atrium, also called Agora. This is a true reception area that enables the organisation of reception functions without access to the parts reserved for staff. Next to the Agora is a multi-purpose area for conferences & other events.

The first and second floors are also structured around this Atrium, a real source of natural light. In this spirit, the tones chosen reinforce the overall luminosity of the building, both inside and outside. The main surfaces are predominantly white, light wood and light grey. The extension provides 1675 m² of office space and includes 6 meeting rooms. The building can function as a stand-alone building with a full range of offices, meeting rooms, conference rooms, kitchenettes, archive rooms, photocopying rooms, and workshops for doctors on call.



The Aile 1000 is part of the improvement process ofthe Saint Pierre clinic,  which is currently experiencing a need for space. The new building has an original layout and triangular shape, meeting very clear objectives:

• integration into a residential district with small building
• the wing is presented as the emblematic front projection of the hospital
• the building is architecturally autonomous & has an independent entrance:
– hence 2 entrances: the Saint-Pierre entrance, which provides a concise visual link with the hospital for the staff
– the Fabiola entrance, which is the official address of the building for external visitors


AILE 1000

The decision to build a new administrative building enabled us to propose a model of workstations that meets current expectations and is based mainly on two objectives:
• creating user-friendly spaces, by designing comfortable areas such as the atrium, coffee corners, and other terraces, in a positive atmosphere bathed in natural light
• the integration of environmental objectives
– to provide a passive energy building (consumption < 15 kWh/m²/year for heating), made possible by highly efficient insulation, airtightness, and solar protection
– prioritising the use of sustainable materials (e.g., aluminium frames, wood, but a small amount of aluminium, as it requires grey energy during production and recycling)
– to provide healthy and safer materials (e.g., linoleum
on the floor, presence of wood, low VOC (volatile organic compounds) content, etc.)
– copious natural light & light colours

energy management

A passive office building was achieved through the implementation of various innovative solutions:
• double flow ventilation with heat recovery (heating/cooling)
• solar input energy management
• solar panels
• high efficiency heating/cooling production
• night-coolin
• high efficiency lighting with daylight-dependent dimming & presence detection
