Belgian architect Vincent Callebaut has recently come up with an interesting and unique solution to turning an old, 1970’s apartment building into a very sustainable complex. His plans call for the transformation of the existing concrete structure into an energy producing building with a green façade.

Callebaut would leave the building as is, but would add 274 planter beds into its ornamental façade. These would hold about 10,000 plants carefully chosen by botanists, to create a sort of vertical garden or green façade, which would increase the building’s thermal performance and clean the air. According to Callebaut’s calculations the plants would capture 50 tons of C02 per year. The windows of the apartments would also have to be exchanged for energy saving ones to further improve the thermal performance of the building. Keeping the green façade flourishing would not be difficult at all, since there would be a drip-feed system that would require maintenance only twice a year. (more…)
