Joe Peach explains the technology behind five materials that will dramatically increase sustainability in the building industry. Among the list are wool bricks which are stronger, greater insulators and don't require firing to set.
The building industry is famously slow to partake in the green revolution says Peach, and has long been left behind by advanced technologies available in transit or energy production. However, the future does still mean progress and many exciting innovations are now occurring in the construction industry, which will sustainably address some of the globes growing housing needs.
Scientists in Spain and Scotland found that simply adding wool and a natural polymer found in seaweed to the clay of a brick makes it 37% stronger, and more resistant to the cold wet climate often found in Britain.
Another innovation comes from the world of concrete production, which accounts for a staggering 7-10% of global carbon dioxide emissions. When producing sustainable concrete crushed glass can be added, as can wood chips or slag - a byproduct of steel manufacturing. Whilst these changes aren't radically transforming concrete, by simply using a material that would have otherwise gone to waste, the CO2 emissions associated with concrete are reduced.

Manufactured Crisis: Losing the Nation’s Largest Source of Unsubsidized Affordable Housing
Manufactured housing communities have long been an affordable housing option for millions of people living in the U.S., but that affordability is disappearing rapidly. How did we get here?

Americans May Be Stuck — But Why?
Americans are moving a lot less than they once did, and that is a problem. While Yoni Applebaum, in his highly-publicized article Stuck, gets the reasons badly wrong, it's still important to ask: why are we moving so much less than before?
