“…However, regarding this point it must be noted that only 10% of Kampong occupants indicate a less frequent cleaning than once per day. Similar findings were obtained in other studies: SBS problems were associated with redecoration in China [43], odor or negative perception of IAQ [74], and relieved in the case of regular cleaning [47].…”

In times of rapid urbanization, increasing usage of chemicals in buildings, and energy saving measures, the topic of indoor air quality (IAQ) demands reinforced attention. Nevertheless, especially in developing countries with urgent building construction needs, IAQ has hardly been examined. This study investigates the condition of IAQ and health of occupants in newly constructed high-rise apartments in contrast to traditional detached houses (Kampongs) in Surabaya, Indonesia. Information on building attributes, cleaning and ventilation behavior, interior sources, personal characteristics and health, especially multiple chemical sensitivity (MCS), was collected through 471 questionnaires. In addition, 76 measurements of TVOCs, formaldehyde and 30 measurements of mold risk were carried out. The results showed that the share of people in apartments with a very suggestive risk of MCS was twice as high as that in Kampongs (17.6% vs. 6.7%). Correlation analysis suggested that for both residential types, health problems, negative smell or perception of IAQ, and higher levels of stress determined higher degrees of MCS. For IAQ, high concentrations of formaldehyde and TVOCs were measured in apartments and corresponded to higher MCS risk, whereas severe mold issues were predicted in Kampongs. This study suggests major shortcomings in the indoor environment in newly constructed apartments for the physical and the mental health of occupants.

Development efforts in the vertical direction should have been better than in the horizontal direction which only requires land to the side. The emergence of new ideas certainly raises the pros and cons, most local geniuses are vertical purity, the compilation passes under the terraced infrastructure there is a feeling of flare/fatigue because it is bypassed by people. The aim of the study is to reveal the vertical relationship with the design of underpasses, and how community acceptance of underpass construction. The methodology used is complicated through interviews with Hindu scholars, Bali, which are then used as a basis for further observation for shareholders so that questionnaires can be prepared. The results of the questionnaire are data of the relationship between vertical and attitude of community acceptance towards underpass development. The data obtained were analyzed by Logistic Regression. The results of the study of vertical simplicity are local wisdoms that need to be discussed and agreed in this modern era. Furthermore, the results of the analysis show that there is a relationship between vertical purity and uneven plot intersection height, as evidenced by the acceptance of the hypothesis at the significance level ? = 0.05. The results of the analysis show "significance <?" or (0.033 <0.05), this means vertical purity, which means significant effect on underpass height design. Alternative designs also need to reduce underpass differences. Invitations are made very necessary as a legal umbrella for the design and manufacture of underpasses. Keywords: Vertical purity, underpass, cemer/leteh, alternative design.

“…Previous findings showed that hot air can be extracted from the house through a ventilated roof design (Roslan et al, 2016). Ventilation is one of the passive designs that should be considered during a house's design stage (Kamaruzzaman et al, 2018). One study concluded that natural ventilation is an alternative method to save energy (Ciampi et al, 2005).…”

One of the major problems in modern housing design is overheating. Occupants suffer higher indoor temperatures due to a lack of natural ventilation. This issue arises because of poor passive design. A good passive design promotes natural ventilation and provides better indoor air temperatures without reliance on mechanical cooling systems. The roofing system plays an important role in a house's design. Since the roof contributes to 70% of the total heat gain, it is important to investigate its design to reduce the impact of overheating. It has been found that many roofs lack a ventilation system in the top part of the house. These openings in the roof provide areas for trapped hot air to exit into the environment. The openings also enhance natural ventilation and allow for effective air circulation inside the house. The optimum roof is designed to tackle this matter by reducing the overheating inside the house, especially during the hottest hours of the day. The hot air exits based on the differences in air density and due to prevailing wind. In this study, the optimum roof was tested on a small-scale model and verified by simulation using computational fluid dynamic (CFD) software, namely ANSYS 18.0. From the data obtained, it was proven that the opening in the roof reduced the indoor temperature. In conclusion, the optimum roof could improve the passive design and help to reduce overheating inside a house.
