Researchers have been pioneering new technology that utilises microbes in building materials to produce resources for the building. There are two great examples being worked on: one uses algae in the façade, the other uses an internal bioreactor-wall. The first, BIQ House, uses a façade system that encapsulates algae which can generate its own supply of energy and heat for the building and even provide hot water. The other, LIAR (Living Architecture), extracts resources from the air, sunlight, and waste water to produce clean air, fresh water, resources to heat the building and more. These projects are very complex and still being developed however they really push the boundary of construction materials and their role within our built environment.
