Abstract |
The economic assessment of apartment buildings was added to the design competition evaluation item of 2014 in order to in order to relatively evaluate a well-planned as applied to the rational. These items will play an important role in reducing the construction cost for building the apartment complex. The purpose of this study is to check the design characteristics of apartment complex getting good score with the examination standard and the effectiveness of guideline through comparing to actual construction costs. The examination standards were chosen as underground parking space per a car, south-facing ratio of sunshine, minimizing the bending outer walls. They made the evaluation results to apply to five completed complex in from 2013 to 2014 with the similar items to evaluate alternatives of the actual design competition. Characteristic of only received a superior scoring is as follows. First, underground parking area per a car was only effective that parking lots could be arranged parallel or perpendicular when the axis of the designed apartment complex was unified. Second, the score maximizing the percentage of sunshine south-facing is high when there are many units facing southward if the floor area ratio is more than 190%. Third, in the case of south-facing ratio of sunshine, how to design the cornered unit of L-type buildings is a factor that increase the difference in scoring. The floor plan related to inner walls of units and common parts of buildings, i.e. staircases, elevators should be designed to remove the bending outer walls as much as possible. This study presents how to reduce the construction cost by design of buildings and underground parking, and check the fact that such design conditions are reflected in the design economic evaluation in LH housing competitions. |
