| Abstract | Building sector contributed 33% of world's GHG emission in 2002. AIT is an academic institute, which is working as a leader to promote energy efficiency and conservation to address and mitigate global warming. AIT consumes about 13 GWh/year (on an average from 2003 to 2007) of electricity, which leads to about 9,300 tons/year of CO₂ emission at power generation. This study describes the electricity saving measures implemented at an academic building for GHG emission mitigation. The electricity consumption and overall trend at the institute was analyzed for the better understanding how electricity is used. Energy building was taken as a pilot building for the implementations of electricity saving measures. Energy building consumes about 120 MWh of electricity per year, and generates about 86.4 tones of CO₂. Among the direct electricity consumption (excluding cooling consumption), lighting is the largest consumer, about 38 and 27 per cent during weekday and weekend, respectively. Therefore, technical measures were focused on lighting system. The technical measures to reduce electricity consumption are the replacement of reflector and reduce lights, the replacement of high efficient linear fluorescent lamps (Master T8 and T5) and electronic ballasts in offices and classrooms, the replacement of linear fluorescent lamps by compact fluorescent lamps at corridor and toilets, the introduction of occupancy sensor & LED (3W) at toilet, the introduction of individual pull switches, and the rearrangement of lighting switches. The overall saving is about 23.5 MWhlyear (22% of overall electricity consumption) or 78,800 Baht/year. This reduction can mitigate CO₂ emission about 16.9 tons/year. SERD consists of six academic buildings whose overall electricity consumption is about 1 GWh per year which leads to 720 tons of CO₂ emission in 2007. If above measures are introduced to all SERD buildings, the estimated saving all probably be about 220 MWhlyear (737,000 Baht/year) which can reduce 158 tons of CO₂ per year. It is obviously seen that there is a significant potential to introduce electricity saving measures in academic buildings. Furthermore, AIT and other institutes should be aware and consider electricity saving strategies for the benefit on both electricity expense and GHG emission point of view |
