The end of the Cold War rendered the CHDACN program strategically absurd. In 1992, the French government officially declassified the network and began divesting. Yet, these buildings refuse to die. Their hyper-resilient structure has proven ideal for 21st-century needs. chdacn buildings
Integrated BIM Modeling: They heavily utilize Building Information Modeling (BIM) to streamline complex construction and ensure precision from planning through to supervision. Yet, these buildings refuse to die
Perhaps the most innovative feature is the elimination of traditional ducted HVAC. Instead, the building’s exterior wall cavity contains a matrix of capillary tubes. These tubes connect to a ground-source or air-to-water heat pump. As outside air diffuses through a breathable membrane and into the wall cavity, it passes over these thermally regulated tubes, emerging at a comfortable 22°C (72°F). There is no forced air, no noise, and no dust circulation. contact our industrial advisory team.
Since "chdacn" appears to be a typo, I have interpreted your request as a guide for "Cardcan Buildings" (a hypothetical concept where architecture mimics the structure of business cards or card catalogs) or, more likely, a guide for "Card-Can" (Cardboard Can) Architecture—a creative, sustainable approach to building using recycled cylindrical cardboard forms.
