In order to examine theoretical underpinnings of preference for built forms, 129 subjects are asked to rate a series of 9 slides of residential houses depicting a wide range of architectural styles on a 5 point scale, for coherence, complexity, excitement, familiarity, and natural harmony, respectively. Based on Lee's (2002a, 2002b) two previous studies addressing the issue of aesthetic beauty evaluation for man-made creatures (e.g., residential housing scenes), this study summarizes several meaningful findings. As reported by all the subjects, first, both "desire to visit" and "desire to live in" turned out to be a good predictor of preference as the two measures are highly correlated in statistically significant levels (99.9%). People who desire to visit a spot are more likely to desire to live in it. Second, Pearson's correlations showed that coherence is the opposite end of complexity. The more likely a housing setting is hanging together, the less likely it looks to be complex. Overall, though, it is not clear that the two variables work directly in that way, as weighted on preference ratings. That is, coherence and complexity are likely to be totally two independent systems that affect the ratings of preference. Third, both excitement and environmental sensitivity (e.g., harmony of a house with its surrounding nature) most highly account for the preference for various housing scenes, while familiarity has only a little effect on preference ratings. Possibly, people like or dislike a visual thing, no matter how much they are familiar with it. Finally, this study suggested that design professionals could communicate effectively with their clients if sets of visual standards as an appropriate communication tool for better design are properly established.

Main purpose of this study is to test the usefulness of the SBE method in measuring ‘complexity’‘beauty’and ‘friendliness’other than ‘preference’. The study results are as follows. 1) The SBE results are as reliable and valid in measuring ‘complexity’‘beauty’and ‘friendliness’as in measuring ‘preference’. However, the degree of reliability and convergent validity can vary according to the inherent charateristics of those abstract quality themselves. 2) The correlation coefficients among the result of rating, SBE, frequency, and paired comparison methods are very high. 3) The perceived beauty of urban residential landscape reaches highest at the higher complexity level than that of the rural residential landscape.

In this study, a consumer willingness to pays for residential heating systems are estimated by economic valuation method. The major Korean residential heating systems in apartments are central heating system (CH), district heating system (DH), and individual heating system (IH). However, DH and IH systems are adopted in newly constructed apartments. Each heating system has own characteristics which residents can identify and value. 700 households in apartment were surveyed to analyze the preference of the residential heating systems and to estimate willingness to pay. We find that the households in DH system are more satisfied with their heating system than the households in other systems overall and that consumers prefer an apartment with DH system than with IH system and the willingness to pay for IH system is less than DH system. The results indicate that DH system has the relative premium which may be caused by the safety and the convenience to manage the system.

This study analyzed users' acceptance and intention to use in addition to needs and preferences of smart home technologies, and identified the differences in technology preference and acceptance by different factors. The subjects were residents in the 40s and 60s residing in the Seoul or suburbs of Seoul, and questionnaires were conducted in the 40s while interviews with questionnaires were conducted in the 60s. A total of 105 questionnaires were used as data, and frequency, mean, crossover, independent sample t test, one-way ANOVA and multiple regression analysis were performaed using SPSS23. The results of this study are as follows. First, hypertension, hyperlipidemia and hypercholesterolemia were the most common diseases among respondents and if there was no discomfort, they would like to continue living in the homes of the current residence. Therefore, the direction of smart home development should support the daily living and health care so that residents can live a healthy life for a long time in their living space. Second, the technologies that residents most need were a control technology of residential environments and a monitoring technology of residents' health and physiological changes. The most preferred sensor types are motion sensors and speech recognition while video cameras have a very low preference. Third, technology anxiety was the most significant factor influencing intention to accept smart home technology. The greater the technology anxiety is, the weaker the acceptance of technology. Fourth, when applying smart residential technology in homes, various resident characteristics should be considered. Age and technology intimacy were the most influential variables, and accordingly there were differences in technology preference and acceptance.
