Abstract: The purpose of this study is to investigate the cost of electricity in education management at Uttaradit Technical College. Details of electricity consumption in eight operational buildings namely administrative, ftindainental education, building constniction, electrical technology, electronics, mechanical technology, auto-mechanic and central supplies were gathered. The information collected were electrical system plan, construction plan, electricity bills. Some information were gathered from on-site sui-vey, eg. electrical equipment installation, together with direct measurement of electrical power associated with lighting , air conditioning and other electrical systems. Energy consumption pnraineters or indices were subsequently evaluated. The results of investigation are as follows: all eight buildings had similar lay-outs, were much of concrete with rectangular shape, oriented in east-west direction. Average space for each building is 2004 m2, 64 % of which was used for various operational tasks. 28 % was air conditioned when compared to 36 % of other space with the total power installation about 83,460.51 kW per building. Out of the total, 33.48 % was for lighting system. The power of electricity installed per unit of building area was 14 kW/m2 and 87 kwlstudent. Another 31.46 %of the total installed power was for air conditioning system with 73 kW/m2 and 81.55 kW/student. The power of electricity installed per unit of building area was 15 kw/m2 and 91 kW/student. Tlle total index of the average power consumption was about 42 kw/m2 andkw/m2 and 249 lcWh/person/year. In educational management, rooms were classified into 4 categories: offices, classrooms, operational and others. Proportion of electricity consumption in each type was that offices consumed 30 %, classrooms 12 %, operational 48 % and others 10 % of the total installed power. When looking into each building, it was found that the power consumption for administrative building was14.22 %, fundamental education building was 6.40 %, construction building was 8.44 %, electrical building was 8.27 %, electronic building was 11.34 %, mechanical technology building was 29.75 %, auto-mechanics building was 18.50 % and central supplies building was 3.07 %. Indices for student's electricity consumption for both certificate and diploma levels were found to be approximately 1,023.18 - 3,220.67 lWh/person/year, 19.29 - 618.35 kWh/full time studendyear and 13.42 - 2,063.73 kWhJfull time studentlyear respectively. Subsequently the exact number of students for each building was estimated in order to find the base budget allocation for the following year. The college overall electricity consumption was about 667,684.10 kWhJyear, out of this amount, 94,976.25 kWhJyear was used for administrative building, 42,736.70 kWhJyear for fundamental education, 56,365.30 kWh/year for building technology, 55,236.25 kWhJyear for electrical technology, 75,775.80 kWhJyear for electronics, 198,626.80 kWWyear for mechanical technology, 123,460.60 kWWyear for auto-mechanics and 20,506.60 kWh/year for central supplies building respectively. The overall annual budget for the college should be 1,068,294.56 bahtlannum. This amount should be allocated for each building as follows : 151,962 baht/year for administrative building, 68,378.72 bahtlyear for fundamental education building, 90,170.08 bahdyear for technology building, 88,377.68 bahdyear for electrical technology building,121,241.28 bahtlyear for electronics building, 317,802.88 baht/year for mechanical technology building, 197,536.96 bahdyear for auto-mechanics building and 32,s 10.56 baht/year for central supplies respectively. This average cost was calculated at 1.60 bahtkWh by using provincial electricity tariff rate. As for the overall consuinption for each curriculum, it was found to be 295,723.29 kWhJyear for certificate level and 293,443.78 kWWyear for diploma level. Annual budget for both levels should be at 473,157.26 bahttacademic year and 469,510.05 bahtlacademic year for certificate and diploma levels respectively. This allocation can also be considered for the following academic year.
