2. 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.

6. Buildings= HUGE opportunity
• Buildings are huge source of carbon
emissions
• Buildings are cheapest place to reduce
emissions
• BUILDINGS ARE THE BEST
OPPORTUNITY TO COMBAT GLOBAL

8. So why aren’t more green buildings being built?

16. 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.

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