The Convertibility Forecast Model of Space Structure in Architecture Programming——Collective Housing in Taiwan for example

Abstract

House refurbishment related to the convertibility of space organizations is nowadays a common phenomenon in Taiwan, reflecting user demands for the diversity of unit plane and space expansion in quantity, and forming an important research topic over the implementation of sustainable development concept in living environment. In this paper, apartment mansion-type amalgamated dwellings were quantitatively analyzed and investigated, and four models, which were dimension combinations of influence factors, were compared through the field survey and logistic regression model (binary regression method). The results showed that the variables in Model IV consisted of three dimensions—space organization, building entity and spatial planning, with the optimal prediction rate (74.5%), so it was regarded as a convertibility prediction model of space organization; the significance and goodness of fit of each model were analyzed by comparing each variable coefficient with the expected symbol, and next, the concrete meaning of each influence factor belonging to each dimension of each model was indicated by means of coefficient correction, which could further predict the convertibility of space organizations, accurately obtain the factors influencing the convertibility prediction, and improve the prediction accuracy. This research, which conforms to the concept of sustainable environmental development, will contribute to construction project planning and design of residential buildings.
