An Analysis of the Determinant s of Business Facility Energy Costs

1. CONTENTS (1) RESEARCH OBJECTIVES The purpose of the study were to analyze determinants of energy cost spent at business facilities and to understand how a size of a building affects the energy cost. (2) RESEARCH METHOD With a total of 109 business facilities in Korea managed by real estate agencies determined a research subject, the study conducted an investigation on energy costs(electrical bills) of those facilities from 2008 to 2010. In order to analyze determinants of energy cost, the study conducted a regression analysis with the energy cost determined as a dependent variable and gross area, square of the gross area, the number of stories, passed years, outdoor temperature, electric capacity, installed capacity and owner of a building as independent variables. (3) RESEARCH FINDINGS According to the results of the empirical analysis, as t he passed year increases by a year, the energy cost increases by 0.09won/㎡. Eelectric capacity increases by one electric unit, the energy cost goes up by 27.053won/㎡. And the buildings owned by major companies were found to spend energy cost more by 1.442won/㎡. It was also reported that the energy cost decreases as much as 21,069㎡ of gross area of a business facility but when it reaches 21,069㎡, the energy cost increases again. 2. RESULTS The study understood that as the passed years and the elect ric capacity increase, the energy cost goes up. And the buildings owned by the major companies would spend more money on energy comparing to other buildings. The energy cost was analyzed that it would decrease to 21,069㎡ of a gross area of a business facility and t hat it would increase again when it reaches 21,069㎡. The study should have looked if there are any other variables to affect the energy cost. The study is also believed to have a limit in that it has excluded high-rise buildings and outsize buildings.
