아파트의 적정 건설층수 결정을 위한 에머지(emergy)평가

Abstract

The cost of the construction and management of new apartment buildings was evaluated using a monetary analysis and an emergy concept to provide a new perspective regarding the housing policy of Korea. The systems of analyses were typical apartment buildings with an area of <TEX>$76.03m^2$</TEX> per household in Korea built on the same size of land area. Three apartment buildings with different stories were evaluated and compared; 5-story, 15-story, and 20-story apartment buildings. The durable years of those apartments were assumed to be 40 years. The total cost of the construction and management of an apartment building was divided into three categories of construction, land purchase, and management. A 20-story apartment showed the highest cost and a 15-story apartment the lowest in the monetary cost analysis. In contrast, the emergy evaluation revealed a different pattern in the cost of construction and management, the cost increasing from a 5-story apartment to a 20-story one. This means that the higher the apartment constructed, the greater the cost in terms of real wealth. This result suggests that new evaluation methodologies like the emergy analysis should be used together with the monetary analysis to provide better insights on the national housing policy.
