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.
