How Do We Get Our Buildings to Be More Efficient?

Buildings are responsible for roughly 40 % of the world's omissions. And that breaks down into roughly ten percent from eo producing the building materials and 20 to 30 per cent how we operate those buildings. I think i read recently that two thirds of our building stock in 20 forty will be buildings that were constructing to day. There is no time to waste. We need to build urgently with a mind towards sustainable building, towards greener and more efficient buildings.
