  • 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 &quot;set in their ways&quot; yetNot Just Energy!!    - Seven Performance MandatesWhat can you do?              - You&apos;re not a designer, engineer, contractor, etc ..... but you are a CONSUMER... you&apos;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 &quot;Solar Powered&quot;, &quot;Net Zero&quot;, &quot;Sustainable&quot;, &quot;Green&quot; etc are similar to the words &quot;wonderful&quot;, &quot;great&quot;, 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

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 http://www.iea.org/<br />www.worldenergyoutlook.org/docs/weo2009/WEO2009_es_english.pdf<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 www.nrc-cnrc.gc.ca/obj/irc/doc/pubs/nrcc51142.pdf<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 />
