3. Building Cycle

4. Building Cycle
• In Design Phase, people (mostly) focus in
design and construction phase.
• It is good if we think about full cycle, at least
until operation.
• Operation in certain period cost more than
design and construction phase

5. Building Cycle Cost

6. What’s Simulation?
• Simulation through modeling is building your
building in computer.
• We can simulate power profile, cooling
capacity needs and energy consumption by
evaluating some criteria
• Detailed simulation can minimized error close
to 3 % in term of energy calculation

7. How Simulation Save Money
1. More accurate cooling capacity calculation
and reduce chiller capacity
2. Getting power profile in peak period to
decide electrical power installation
3. Comparing some designs to get optimum
energy savings with logical investment

9. Case Study : ICE

10. ICE Modeling
• Create model based on updating data

11. What We Saved?
In Design Process :
• Chiller capacity reduced from 9615 TR to 5758
TR
• Power capacity (based on simulation) is 14
MVA (Before 16.7 MVA)
• Glass optimization by reducing 30 % of
expensive double glass usage
