2 The Building Sector: A Heavy Footprint the building sector has the greatest poten2al of any sector for reducing GHG emissions, and it is impossible to meet the climate change commitment without addressing building energy performance

3 How it works??? Addressing Building Energy Performance from day one.

4 Building Industry Transforma2on Traditional Middle Age Modern/ Unique Green Building Net Zero Energy High performance building Greener / More engineering

19 Future Growth in Building Stock: No of Buildings : 2% New Construction The building stock is projected to grow to nearly 40 million square feet. About 75 percent of the buildings will either be built or renovated in that period. This creates an extraordinary opportunity to achieve significant emissions reduc)ons in the building sector

20 NEW BUILDING Start from zero Focus : Design & Construction Design Intent Promised Performance Start from base building Focus : Operation & Maintenance Existing Operational System Actual Performance EXISTING BUILDING Test & Comm Verification Proper O&M not as BAU

21 Design Concept Cons- truction Operation & Manual Expected Performance Actual Performance Test & Comm Design Verification Proper O&M not as BAU

22 Existing Building BCA TOWER 2 Saving vs Ave : 30,24% Saving vs Previ : 18,6% PLATINUM - EB 22

23 Conclusion What is benefit of green building? Financial Benefit Na2onal Benefit Op2mizing investment, reducing opera2ng cost, improve profit & financial performance Increase building standard, reducing the usage of natural source, conserve the source to extend the availability Global Benefit Reducing CO2 emission, reducing global warming, figh2ng the climate impact for our next genera5on
