COMPARATIVE STUDY OF POST-OCCUPANCY-EVALUATION OF TOWNHOUSES CONSTRUCTED WITH LOAD-BEARING WALL AND CONVENTIONAL WALL SYSTEMS

Abstract

From economic crisis due to COVID-19 epidemic, real estate developers must find ways to reduce production cost, cycle time, and labor usage in their projects in order to maintain their competitive advantages. Thus, load bearing wall construction systems have been adopted by real estate developers even though some developers still use conventional construction systems in their projects in order to respond to the demand of some customers. From this reason, the researchers therefore aimed to study the customers’ satisfaction to the different wall construction systems, e. g. load bearing wall systems and the traditional wall construction systems, using the concept of Post Occupancy Evaluation (POE). The research was done by collecting data from interviews of the eight after-sales service staff who are responsible for both types of townhouses, with different sub-types and price levels, and analyzed the acquired data by Content Analysis Technique. The results of the research concluded that Satisfaction after using the building among the customers living in the residences with different structural systems had the same satisfaction in different aspects, only the satisfaction in the absorption and desorption of moisture. Modification of the building Cracks after use and leaks at various points of the building can only be seen inconsistent with opinions. The results revealed the difference in post-occupancy satisfaction for different structural systems, that help developers select wall construction systems to enhance the customers’ long-term satisfaction and quality of life.
