| Abstract | The overall objective of this study is to evaluate the performance on cooling load reduction of insulation and reflective coating that have been implemented at Outreach building and Administration building respectively and the performance of these techniques if they are implemented at Energy building!. At Outreach building third floor, the study reveals that the implementation of Exterior insulation finishing system (EIFS) at wall and 9 inches fiber glass at roof can decrease cooling load by 32.4% or about 68,000 Baht/year due to the increase of thermal resistance from added insulation resulting in small amount of heat able to pass. The economic analysis indicates that simple pay back period is 27 years. In case of paint reflective coating at roof of Administration building, the study shows that about 20,000 Baht/year or 12% of total cooling load can be reduced because of large amount of solar radiation is reflected back to the atmosphere. The simple pay back period of this technique is about 48 years. When these techniques are applied to Energy building 1, it was found that placing fiber glass at roof is the appropriate technique. It can reduce cooling load by 11% or 20,000 Baht per year. The important reason why other techniques can not mitigate cooling load as expected is the existing good design of Energy building 1. Energy building 1 has several configurations for enhancing cooling load reduction. Therefore, all techniques show long simple pay back period. Moreover, they also have very high investment cost. Therefore, for old buildings implementation of these techniques will not give a good benefit only from cooling load reduction. On the other hand, these techniques are very important for new building at design stage since they will not only decrease cooling load but also reduce capacity of chiller, pumps, and accessories. Furthermore, the study demonstrates that the implementation of/energy conservation measures during 2007-2008 have reduced electrical energy by 30% or about 108,000 Baht/year. The simple pay back period is 2.47 years. The measures are not only mitigating electrical energy but also reducing carbon footprint of Energy building 1 by 22.66 tons of CO₂/year |
