A Study on the Estimation Analysis of the Optimum Economic Life-Span of a Multi-Housing Complex |
| Abstract |
Generally, the life-span of a multi-housing complex is over 50 years, but in reality they are usually demolished after 20 years in spite of its remaining life expectancy. Thus, this research focuses on the estimation of the optimum economic life-span of a multi-housing complex. To estimate the minimum total cost point of start to finish of a multi-housing complex, we'll apply MAPI(Machinery and Allied Product Institute) and LCC(Life Cycle Cost) theory. Under the assumption that building life expectancy is 50 years, initial cost is ￦421,212/㎡, total sum of the yearly running cost during the life expectancy is ￦2,154,499/㎡(5.115 times of initial cost), discount rate is 6.24%, followings are results of this study. First, yearly running cost is as follow RC = 0.7097t4 - 38.803t3 + 806.95t2 + 11045t - 496.52 (R2 = 0.98) Here, RC = running cost, t = given years Second, the optimum economic life-span of the multi-housing complex is 35∼36 years, which is based on the theories of MAPI and LCC. |
