A Study on User Satisfaction of Vertically Extended Buildings

摘要

The present study aimed to serve as fundamental data for improving user convenience at the initial consulting stage of future extension and remodeling of buildings. In order to analyze the users' degree of satisfaction on existing extended buildings, we analyzed the evaluation characteristics in each category of entire building appearance, interior and exterior material conditions, indoor environment and construction period. The analysis results showed that it is important to ensure the unity among existing buildings in the extension of public buildings within the residential complex, and the use of heterogeneous materials with existing buildings, including lightweight frame panel (aka, sandwich panel) is to be avoided. Also, it is necessary to use interior and exterior materials that can compensate for this and employ a system that can substitute the RC rigid frames and lightweight panel frame system frequently used in existing extension and remodeling because it was shown that degree of satisfaction of soundproofing and insulation performance among indoor environment performance is considerably low compared to the other categories for most users who use existing extension floors.
