  • Ideas for PhillippinesPresentationMe and my projectIntoduction to buildings     - Main focus of this presentation will be about energy    - Background on how buildings use energy    - Special considerations for this SE Asia region    - End Goal of Buildings - Not just energy but also High Performance!!    - What can you do? Building Energy Impact in the world    - Current consumption/production of energy    - Share that goes to the built environment - SHOW TREND on a google MOTION GRAPHHow do buildings consume energy - Have people guess what the main sources of building energy consumption aredynamic graph slide - of TYPICAL commercial office building (provide disclaimer at end)    - Computers/Appliances/etc? - share?    - Climate Conditioning -     - LightingWhat factors affect building energy consumption    - Occupant type    - Building Use    - Climate!!!!Factors of SE Asian Climate - show climactic mapChallenges    - HUMIDITY - Energy, Indoor Air Quality, etc etc    - First cost mentality - convincing building owners that the extra investment is worth the price    - Conservative, shrewd environmentOpportunities   - Opportunity to adopt new technologies as first conditioning project - people not "set in their ways" yetNot Just Energy!!    - Seven Performance MandatesWhat can you do?              - You're not a designer, engineer, contractor, etc ..... but you are a CONSUMER... you're duty as a responsible citizen in the world is to be                 an EDUCATED consumer              - First be aware of the difference between the MARKETING and REALITY                    The words "Solar Powered", "Net Zero", "Sustainable", "Green" etc are similar to the words "wonderful", "great", etc                    DEMAND quantifiable adjectives such as - btu/sqft/yr, etc (in a perfect world people would understand the significance of these)                    - Easy to understand benchmarking systems are being developed - Singapore.... research other countries in the region for green building rating The End

  • 1. SMART GREEN BUILDINGS
    CLAYTON MILLER
  • 2. What is a “Green” building?
    How do buildings use energy?
    What is a “Smart” building and how can that save energy?

    Climate Control 34%
    Everything Else 27%
    Water Heating/
    Cooking/Refrigeration
    13%
    Lighting 26%

  • 9. Building Energy Impact - DISCLAIMER
    Building Energy Consumption IS HIGHLY dependent on many factors:
    • Climate
    • 10. Localized Weather Effects
    • 11. Shading
    • 12. HVAC System Type
    • 13. Schedule
    • 14. Occupancy Fluctuations
    • 15. Building Envelope
    • 16. Occupant Activity Level
    • 17. Space Use
    • 18. Etc.
  • Southeast Asia Challenges – Climate
    HEAT and HUMIDITY!!

  • 20. New A/C Design Technologies
    New 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
  • 21. 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%

  • 22. 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
  • 23. 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.

  • 24. 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!
  • 25. “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
