“Buildings account for 40% ofglobal greenhouse gas emissions.Make them more energy efficient
and you help fix a mega-problem.”
“There’s nothing else I could do . . .
and have that kind of impact.”
Henry Paulson, former Goldman Sachs CEO, U.S. Treasury Secretary, and Nature Conservancy Board Chair, whose engagement with Xi Jinping and other China leaders spans decades, discussing his efforts to make new Chinese buildings more energy efficient.

The certification application requires performance data,much of which is affected by user behaviors.
3-15 points - alternative commuting transportation – “demonstrated % reduction in conventional commuting trips”
1-18 pts – optimize energy efficiency performance – “energy performance must be based on actual metered energy consumption”

Recap
EBOM & EPC’s = More Sustainable Existing Buildings
real-word measured improvement requiredChina & SE Asia regional challenges
Building Operations = 40% of GHG Emissions 75 years to replace the existing buildings
China accounts for 1/3 of the world’s existing building floor area
HKU’s CYC/TTT = Important Example for China & Asia
