The beginning of civilization as we know it really started with a series of material innovations; the Bronze Age and the Iron Age set us on the path to where we are now, after all. So it makes sense that the history of architecture is also deeply engrained in technological developments of the time. Skyscrapers would have never reached such heights without developments in steel, for example, and fa\u00e7ades would have never slimmed down without thin-shell concrete.<\/p>\n
In a time that is so buzzing with technological development, we cannot help but salivate a little at the material prospects for architecture that are now emerging. Read on to see what drastic innovations may be transforming the built environment in the near future.<\/p>\n
A large crack down the chimney of Corbusier\u2019s La Tourette is a typical challenge that modernist concrete icons pose for preservationists. From <\/i>Walking Through Le Corbusier by Jos\u00e9 Baltan\u00e1s (London: Thames and Hudson, 2005), via <\/i>Metropolis<\/a><\/p>\n The greatest downfall of concrete \u2014 the world\u2019s most widely used building material \u2014 is unavoidable cracking caused by exposure to water and chemicals. Butrecent developments<\/a> by a team in the Netherlands extends the life of this popular material by infusing concrete with bacterial spores that patch up cracks when water seeps through. This amazing innovation has now begun to be used in real-world projects, including a set of self-healing water tanks<\/a> in the Netherlands.<\/p>\n The Shimizu TRY 2004 Mega-City Pyramid<\/a> concept for Tokyo is a proposal so large that it can only be completed with the help of carbon nanotubes; images via Dark Roasted Blend<\/a>.<\/i><\/p>\n Nanotechnology is pushing materials science beyond the limits of what once seemed impossible<\/a>. When combined with ultra-high-strength concrete, nanomaterials such as Carbon Nanotubes (CNTs) create a material so strong in both tension and compression that steel rebar is no longer needed in construction, therefore expediting the building process. The possibilities don\u2019t stop there. Other developments include ultra lightweight<\/a> (super-strong) materials as well as another form of self-healing concrete<\/a>.<\/p>\n This fully transparent solar cell could make every window and screen a power source; via <\/i>Extreme Tech<\/i><\/a><\/p>\n Nanotechnology could also greatly improve the efficiency<\/a> of solar panels, making it possible to embed a single panel with a huge array of individual solar cells. This would greatly reduce the cost of the technology, finally making solar energy a viable alternative to fossil fuel. Other explorations in making solar energy cheaper include dye-sensitized solar cells<\/a> (DSSCs), DuPont\u2019s silicon ink<\/a> component and fully transparent solar panels that could replace standard glass in windows across the world.<\/p>\n In addition to insulating, Aerogel also has the unique property of being translucent, potentially redefining the \u201cglass house\u201d; photo of Hemsworth Managed Offices (Atkins Architects) via Kalwall<\/a> by David Jewel.<\/i><\/p>\n Whether it\u2019s climate change or simply daunting energy bills, nearly everyone is demanding more efficient, greener new buildings. Insulation is therefore a hot topic, especially when it comes to aerogel \u2014 not only one of the lightest materials available, but also one of the highest insulators (it also held 13 other Guinness World Records in 2011.) Originally developed by NASA, a commercial spin-off has emerged in the form of Thermablok<\/a>, specifically designed for residential and commercial uses.<\/p>\n Hopefully they don\u2019t actually sweat <\/i>that much; image via Advanced Science News<\/a>. <\/i><\/p>\n Though the idea of a \u201csweaty\u201d building sounds rather \u2026 unpleasant \u2026 this new material<\/a> from researchers at ETH-Zurich that aims to make your building perspire is anything but. The rooftop material absorbs water when it rains and only releases it when the heat is raised to a certain temperature. The resulting evaporation will in turn keep the house cool \u2014 much like the process of human sweat.<\/p>\n MASS Design<\/a>\u2019s hospital in Rwanda uses architecture to reduce the risk of disease spreading through the facility. New SLIP materials could also help with the cause in the future. <\/i><\/p>\n Stopping the spread of disease in a confined space such as a hospital is no easy task, involving continuous disinfecting and even the occasional architectural reorganization. But now a team from Harvard is investigating an alternative<\/a> that would produce a \u201cslippery liquid-infused porous surface\u201d (SLIP) that would let bacteria slip right off. In addition, the material could ward off dust, ice and graffiti, making it a tantalizing prospect to industries outside of just health care.<\/p>\nSelf-Healing Concrete<\/h2>\n
