新技术改造外墙：办公建筑

? Crac ? is a public management organization located in the heart of the city. The project involved energy and aesthetic renovation of the building envelope while maintaining the building's activity. Ultimately, the operation reduced the building's energy consumption for heating and cooling by a ratio of 1 to 10! These performances are now better than those required for a new building.

The construction concept was based on a simple idea: to wrap the entire building in a new prefabricated insulating skin, without touching the existing fa?ade. This meant that employees could remain in the building while avoiding the costs of moving twice and having to stop work.

Following a digital scan of the entire facade, dozens of prefabricated wood panels were fixed to the existing balconies, revealing the whole volume in just a few days.

All the building's new technology was placed in the gap created between the old and new facades, to enable the occupants to continue working in the best possible conditions. The existing facade was dismantled and removed as soon as the new fa?ade was operational.

The project also gives the building a new architectural expression, fully consistent with its construction system. The materials used are simple, and light and emphasize the connections between the panels.

The contrast between aluminum and yellow highlights the entrance device and sunshades. The inside of the skin, in contact with the building's interior spaces, is warmer: the interior fir wood finishes contrast with the technological character of the exterior fa?ade, offering a soothing dimension to the spaces. The construction of a series of furniture units integrated into the facade takes advantage of the interstitial space, offering occupants new storage facilities.
