The future of design requires thinking innovatively about the way current construction techniques function so we may expand upon their capabilities. Sustainability has evolved far beyond being a trend and has become an indelible part of this design process. Sustainable solutions have always pushed against the status quo of design and now the Structural Technology Group of Universitat Politècnica de Catalunya – BarcelonaTech (UPC) has developed a concrete that sustains and encourages the growth of a multitude of biological organisms on its surface. We have seen renditions of the vertical garden and vegetated facades, but what sets the biological concrete apart from these other systems is that it is an integral part of the structure. According to an article in Science Daily, the system is composed of three layers on top of the structural elements that together provide ecological, thermal and aesthetic advantages for the building.
