  • 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

    2. 2. What is a “Green” building?<br />How do buildings use energy?<br />What is a “Smart” building and how can that save energy?<br />
    3. 3. For me: “Green Building”= <br />Highest <br />Performance<br />+<br />Lowest <br />Resource <br />Consumption<br />and Environmental<br />Impact<br />Thermal<br />Spatial<br />Visual<br />Acoustic<br />Indoor Air Quality<br />Building Integrity<br />Energy<br />Water<br />Natural Resources<br />Pollution<br />Green House Gases<br />Money<br />

    21. 21. Southeast Asia Challenges – Future Growth<br />According to 2009 World Energy Outlook:<br />Energy Infrastructure - $1.1 Trillion needs to be invested by 2030<br />ASEAN Primary Energy Demand forecasted to increase 76% between 2007 and 2030<br />Annual growth rate of 2.5%<br />Source: 2009 World Energy Outlook, International Energy Agency<br /><br />
    22. 22. Southeast Asia Opportunities – Future Growth<br />The opportunity exists to grow in the RIGHT way using Building Energy Benchmark systems and Performance Requirements using CLIMATE specific technologies<br />
    23. 23. Building Industry’s BIGGEST CHALLENGE = Performance Gap<br />Marketed/Designed vs. Actual Performance: “Do LEED-certified buildings save energy? Yes, but…”<br />On average, LEED buildings use 18–39% less energy per floor area than their conventional counterparts.<br />However, 28–35% of LEED buildings use more energy than their conventional counterparts. <br />Source: Do LEED-certified buildings save energy? Yes, but...; Newsham, G.R.; Mancini, S.; Birt, B. – Canadian Institute of Research in Construction<br />
    24. 24. Performance Gap Solutions<br />Rated Buildings are mandated to maintain a performance requirement through monitoring<br />Buildings can detect, diagnose, and possibly “self-heal” system faults<br />Occupants are given the opportunity to control, monitor, and be educated about their indoor environment!<br />
