Aile 1000

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

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
