Abstract

This study suggests an optimization method for the life cycle cost (LCC) in an economic feasibility analysis when applying energy saving techniques in the early design stage of a building. Literature and previous studies were reviewed to select appropriate optimization and LCC analysis techniques. The energy simulation (Energy Plus) and computational program (MATLAB) were linked to provide an automated optimization process. From the results, it is suggested that this process could outline the cost optimization model with which it is possible to minimize the LCC. To aid in understanding the model, a case study on an industrial building was performed to outline the operations of the cost optimization model including energy savings. An energy optimization model was also presented to illustrate the need for the cost optimization model.

Summary

Introduction

Korea is the fifth largest oil importer in the world. Since Korea does not produce oil, 97% of the fossil fuel used for energy is imported [1]. Energy policy for buildings includes strengthening the energy saving standards of a building, such as the U-value of the building envelope, or enforcing compulsory use of renewable energy sources. To adjust to these measures, construction companies have been meeting only the minimum standard each time regulations are tightened. This is caused largely by the misunderstanding that efforts to reduce energy consumption undermine profitability, meaning that energy saving buildings are not attractive to investors who wish to maximize profit
