The authors evaluate indoor air quality in apartments built according to the South Korean Clean-Healthy House construction standard. The evaluation includes three types of residential units with differing gross floor areas. Indoor air was analyzed for formaldehyde (observed range 52.0–99.2 ug/m3), acetaldehyde (14.6–61.0 ug/m3), benzene (0.6–1.3 ug/m3), toluene (161.8–371.0 ug/m3) ethylbenzene (6.5–17.0 ug/m3), xylene (14.7–45.0 ug/m3), and styrene (37.7–112.5 ug/m3). The concentrations of all analyzed substances were within the South Korean guidelines. The findings confirm that the Clean-Healthy Homes initiative has led to a greatly improved indoor air environment compared to existing newly built apartment blocks in South Korea. However, this construction standard is applied only to large apartment developments comprising 1,000 or more units, and it seems that further effort should be made to extend the standard to stand-alone residences and small-scale apartment blocks in order to ensure that indoor air quality is maintained more widely.

PVC floor material is widely used in Korean homes, and people customarily sit or lie on the floor surface. This could potentially put residents of such homes at high risk of exposure to semi-volatile organic compounds (SVOCs). However, there is a current lack of information regarding the degree of SVOC contamination in Korean homes. Therefore, this study was implemented to measure SVOC concentration in the air and house dust in homes and kindergartens, places where children spend long periods of time. The substances analyzed were 2E1H, D6, DEP, TBP, TCEP, DBP, TPP, DOA, and DEHP. Amounts of 2E1H, D6, DEP, DBP, and DEHP were detected in the air of the homes included in the study, and the average air concentrations of DBP and DEHP were 0.53 μg/m3 and 0.28 μg/m3, respectively. The average dust DEHP concentrations in the rooms of homes and kindergartens were 2,800 μg/g and 4,350 μg/g, respectively, showing that higher values were measured in kindergartens. The measured DEHP concentrations in the dust of both homes and kindergartens where PVC floor materials are used were high.

This study investigates indoor thermal conditions in traditional Chinese shophouses (CSHs) in Malacca, Malaysia, using field measurements and focuses on the cooling effects of courtyards. The results indicate that the indoor air temperature in the living rooms of CSHs was approximately 5-6°C lower than the outdoor temperature during the day primarily due to structural cooling effects with night ventilation, whereas the indoor air temperature at night was similar to the outdoor temperature. If the thermal adaptations of the occupants were considered, then the thermal conditions in the living rooms were acceptable for most of the day. The results indicate that the front courtyards functioned as a cooling source for the surrounding spaces in the CSHs.

Many cities around the world have experienced fast urbanization with suburban development. The organic urban forms of old towns or existing city centers have been extended with modern grid systems. However, little research has been conducted to identify the impact of modern grid forms on the organic urban structure in the city center. This study aims to examine the transformation of urban morphology using space syntax for the case study of Barcelona, Spain, which is an ideal case city because of its organic city center surrounded by an orthogonal urban system. The result showed that at the car-oriented global scale, the city center area with an organic urban form loses its importance in terms of space syntax indexes such as choice and integration values. However, the organic structure becomes more important at the pedestrian-oriented local scale. Furthermore, adding the grid structure to the original organic form increases the relative importance of the organic form in Barcelona′s city center. This finding indicates that a grid system and an organic form are not in opposition to each other, but can instead be complementary. This study implies that the integration between organic form and grid system is very important and necessary for urban regeneration in many cities.

In this paper, a study on the various indigenous materials used for the construction of the traditional houses of Myanmar is made. The aim of the study is to collect the basic data for further study about the influences and effects of the use of indigenous building materials on the human comfort inside of the house in correlation with the environment and weather condition. Detail investigation is made on the villages of some races; Bamar, Mon, Shan and Inn-thar.The authors show the type of structure of house in Myanmar and characters of the investigated houses based on the fieldworks and questionnaire, which are located at ten traditional villages and a new developed town. Various kinds of wood and bamboo used for construction materials and leaves and grasses used for roofing are shown as the common indigenous materials. Actual conditions of the indigenous materials used for structure, roofing, flooring and walling in each village and new town are clarified.
