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?

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!
