This document discusses smart green buildings and how they can save energy. It defines a green building as one with the highest performance and lowest resource consumption and environmental impact. It notes that end-use efficiency is the largest contributor to reducing CO2 emissions. Buildings in Southeast Asia face challenges from heat and humidity, and the region's energy demand is forecast to increase significantly. Smart buildings can help close the performance gap between predicted and actual energy use through technologies like energy monitoring, automated fault detection, and giving occupants feedback to influence energy usage.
2. What is a “Green” building? How do buildings use energy? What is a “Smart” building and how can that save energy?
3. For me: “Green Building”= Highest Performance + Lowest Resource Consumption and Environmental Impact Thermal Spatial Visual Acoustic Indoor Air Quality Building Integrity Energy Water Natural Resources Pollution Green House Gases Money

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. 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
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
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
Many people have seen this graph – illustrates the magnitude of change occuring
