Abstract
Recently, the energy consumption of domestic educational facilities has been steadily increased and they were classified as a top energy consumption business in building industry in 2009. In order to prevent the energy overconsumption in educational facilities, the government requests educational facilities to make a plan for energy saving while new building, operation, and extension. However, they have been considering only the amount of energy saving as criteria in the phase of making energy saving plans, not the input costs. Especially, the costs for energy saving are limited in educational facilities, so that they need a cost-effective method when selecting energy saving measures. This paper proposes a model for selecting energy saving measures which derive maximum energy saving within allowable cost using genetic algorithms. As a result of this research, the developed model will be utilized for making a cost-effective plan in educational facilities.
