REQUIREMENTSREQUIREMENTS
OPTION A : Applicable for buildings where energy benchmark is not available. To demonstrate energy savings over its own historical baseline versus over last 3 years.
15 points given for achieving 10% energy savings from the baseline.
0.2 point for every subsequent percentage improvement from the baseline of 10 % savings.
Part 1-1 ENERGY EFFICIENCY
OPTION B : Applicable for Retail Mall, Hotels & Office buildings based on available energy benchmark. For Office, Energy Efficiency Index (EEI) is 215 kWh/m2/yr.
15 points given for achieving the energy benchmark.
0.2 point for every subsequent percentage improvement from

Gross floor area (GFA) = 65,000 m2
Operating Hours (OH) = 60 hrs/week
EEI = (12,345,678 / 65,000) * (55 / 60) = 174 kWh/m2/yr
Percentage improvement = (215 – 174) / 215 = 0.19 or 19%
Points = 15 + (19% x 0.2) = 18.8 pts
EEI for Office buildings = (TBEC / GFA) * (55 / OH)
