Buildings produce a LOT of CO2 emissions
The energy consumed in manufacturing and transporting building materials, constructing homes and offices, and heating and cooling
structures represents almost 45 percent of China’s total energy use.

Importance of design
Although up-front building and design costs may represent only a fraction of the building’s life-cycle
costs, when just 1 percent of a project’s up-front costs are spent, up to 70 percent of its life-cycle costs may already be
committed.

So what’s really holding us back?
LACK OF AWARENESS
