While VE in South Korea must be performed according to law, there is no standard evaluation method for the design values and value indices, and few studies have been conducted on this topic. The methods that are currently in use convert the function and performance evaluation values to grades. Although these methods allow evaluation factors with different properties to be handled in the same way, they can produce different revaluation results depending on the grade setting. Therefore, for the reasonable and effective improvement of the values of buildings, a reasonable value evaluation model that can produce objective and consistent results is needed. In this study, a value evaluation process that systematizes the building element design evaluation process was proposed. A numerical value evaluation model for calculating the cost, physical performance, workability, and index used in the evaluation process was also proposed. The normalization and linear-transformation theories were applied to the proposed numerical value evaluation model, which produces a value index by conducting value evaluation based on mathematical theories rather than by converting the function and performance to grades, as is currently being performed in the existing methods. Thus, the proposed model is expected to yield reliable and objective evaluation results.
