Environmentally Conscious

 

Built
Environment
and
Climate Change
have a lot in
common

Climate change is generated by GHG (Green House Gases) and the World Building Council estimates that, globally, up to 30% of worldwide GHG emissions, including carbon, are generated by the built environment. The built environment is also responsible for significant amounts of air, soil and water pollution, and millions of tons of landfill waste.

As a recent report from McKinsey provocatively states, construction industry is ripe for disruption unless serious and urgent measures are undertaken.

 

This is a situation that clearly needs to be changed.

 Conventional construction has used traditional materials for more then 150 years such as concrete and steel, like there are no alternatives. Besides, concrete hardens as a result of the chemical reaction between cement and water (hydration). The common water-cement ratio ranges from 0.35 to 0.60 kgs, meaning that for every ton of cement water consumption could vary from 350 kgs up to 600 kgs (1). Furthermore, industry itself has the lowest innovation rate and productivity growth averaged 1 percent a year over the past two decades, compared with 2.8 percent for the total world economy and 3.6 percent for manufacturing.

(1) Because concrete may take up to 28 days to fully cure, additional water is often added to the concrete to compensate for evaporation. When this added water is considered, the overall water consumed annually during concrete production and operation is estimated to be between 2.15 to 2.6 billion tons, or 2.15 to 2.6 trillion liters worldwide.
