ET-90-2 Shrestha, Rabindra Bahadur Energy conservation in the Petroleum Authority of Thailand (PTT) office building, Bangkok Bangkok : Asian Institute of Technology, 1990 135 leaves Research studies project report ; no. ET-90-2 A Research Study Submitted in Partial fulfilment of the requirement for the degree of Master of Engineering, School of Environment, Resources and Development Research Studies Project Report (M. Eng.) - Asian Institute of Technology, 1990 A study on energy uses in the Petroleum a u thority of Thai lan d (PTT ) Office Building was condu cted. Energy Audit of various system such as electrical system, air conditioning system were carried out. In 1989 the total energy consumption of the Office Building was about 60240 00 kWH and costed 11.98 million baht. A detail electri cal measu rement of different feeders were made. The break down of electrical energy usage in various energy systems are presented. The percentage of electrical energy contributed by Air conditioni ng system, Lighting , Lifts , Miscellaneous were 61.39% , 23.34%, 6.36% and 8.92% respectively . The electrical energy usage indices and cost effectiveness are presented to compare the effectiveness of the energy usage. The average monthly electrical indices are 16.90 kWH/m2 and 33 . 60 bah t /m 2 respectively. The power indices for Air conditioning system and Lighting are 39.84 W/m 2 and 12.55 W/m2 respectively . The opportu nities for energy conservation in power and thermal energy systems are identified , analyzed and recommended. The monetary saving d u e to reduction of peak demand is 233580 baht per year . The energy saving from reduction of demand is 134550 baht per year. From the redistribution of Transformer the saving will be 38261 baht per year. From energy conservation in lighting system the saving is 622077 bah t per year. A detailed simulation work of building energy system were carried out. From the simulation work the result shows that the external heat gain is the major source of cooling load wh i ch represents 65 . 1% , I n filtration 15.3% , Equipment 5.4%, people 7 . 3% and Lighting 6 . 9% respectively. To reduce the cooling load using protective polyes ter films in the window wi ll save 438126 baht per year . Also increasing the thermostat set point to 75°F will save 536406 baht per year.
