These are images of OostCampus by Carlos Arroyo Architect. The project is the city hall and municipal services center for the town of Oostkamp, Belgium. Formerly, the building was some kind of bottling facility for Coca-cola, but Arroyo won a competition four years ago to imagine a different future for the site. He elected to keep the exiting building, but modify it quite extensively, filling the interior with fiber and gypsum shells. These shells are what look like giant bubbles on the inside, turning the ceiling into a choppy plane.

The winning project, by the Madrid studio lead by Carlos Arroyo, opted for a radical re-use of the large industrial existing building, including foundations, floors, supporting structures, outer skin, insulation, waterproofing, and all recoverable services and equipment: power station, heating plant, water pipes, fire hoses, sewerage, and even parking area, fencing and access.

The reuse of the existing is a basic criterion of sustainability. The “gray energy” (energy used for the production of something) is often discarded or simply ignored. If we demolish an existing structure and build again, we will use more energy and resources than the most efficient of buildings can of save in its life span.
