SMART GREEN BUILDINGS
CLAYTON MILLER
What is a “Green” building?How do buildings use energy?What is a “Smart” building and
how can that save energy?
For me: “Green Building”= Highest Performance+Lowest Resource Consumptionand EnvironmentalImpact

World Energy Outlook 2009 Report
“End-Use efficiency is the largest contributor to CO2 emissions abatement in 2030, accounting for more than half of the total savings in the 450 Scenario, compared with the reference scenario”

Main Energy Use In Commercial Buildings
Water Heating/Cooking/Refrigeration13%
Lighting 26%
Climate Control 34%
Everything Else 27%

Building Energy Impact - DISCLAIMER
Building Energy Consumption IS HIGHLY dependent on many factors:• Climate• Localized Weather
Effects• Shading• HVAC System Type• Schedule
• Occupancy Fluctuations
• Building Envelope• Occupant Activity
Level• Space Use• Etc.

New A/C Design TechnologiesNew types of Air Conditioning systems which
are more appropriate for humid climates!• Single Coil, Twin Fan Air Conditioning
System• Dedicated Outdoor Air Systems• Desiccant Heat Dehumidification
Technologies• Natural Ventilation
Southeast Asia Challenges – Future Growth
According to 2009 World Energy Outlook:• Energy Infrastructure - $1.1 Trillion needs
to be invested by 2030• ASEAN Primary Energy Demand
forecasted to increase 76% between 2007 and 2030
• Annual growth rate of 2.5%Source: 2009 World Energy Outlook, International Energy Agency http://www.iea.org/www.worldenergyoutlook.org/docs/weo2009/WEO2009_es_english.pdf
Southeast Asia Opportunities – Future Growth
The opportunity exists to grow in the RIGHT way using Building Energy Benchmark systems and Performance Requirements using CLIMATE specific technologies
Building Industry’s BIGGEST CHALLENGE = Performance Gap
Marketed/Designed vs. Actual Performance: “Do LEED-certified buildings save energy? Yes, but…”–On average, LEED buildings use 18–39% less
energy per floor area than their conventional counterparts.–However, 28–35% of LEED buildings use more
energy than their conventional counterparts.

Performance Gap Solutions
Rated Buildings are mandated to maintain a performance requirement through monitoring
Buildings can detect, diagnose, and possibly “self-heal” system faults
Occupants are given the opportunity to control, monitor, and be educated about their indoor environment!
“Smart” Buildings• Interoperability of building
information systems• Optimization of system set points
using energy simulation• Demand Response Technologies and
“smart grid” integration• Real Time Occupant Feedback
