One of the factors to enable energy efficiency in buildings is creating thermal comfort for the occupants of buildings so that the artificial vaporization is not required. The thermal sensation vote (TSV) is an indicator in analyzing the occupants’ satisfaction on the thermal comfort of their buildings. Some climate variables that relate to the TSV include air temperature, humidity, and wind speed. The three variables can be combined into a variable using a psychrometric chart. The combined variable is known as an effective temperature. The present research aims at analyzing the connection between effective temperature and TSV in vernacular houses in the tropical mountain and beach locations and comparing the results of the analysis. The quantitative method was employed in the research by measuring the variables of climate using a thermal measuring instrument. The TSV was measured with ASHRAE (American Standard of Heating, Refrigerating, Air-Conditioning Engineer)’s seven-point sensation scale. The measurement was carried out in transitional periods from the dry season to the wet season. Interpretation of graphs and charts was made for analysis based on the variable of effective temperature. The results of the research indicated that there was a connection between effective temperature and TSV. The effective temperature in vernacular houses in tropical mountain locations tended to be lower, and therefore the cool thermal sensation had the greatest percentage of TSV. Meanwhile, the effective temperature in tropical beach locations tended to be high, and therefore the warm thermal sensation had the greatest percentage. In a neutral scale, the percentage of TSV in tropical mountain locations was greater than that of TSV in tropical beach locations. Therefore, it is concluded that the occupants of vernacular houses in tropical mountain location felt more comfortable than those of vernacular houses in tropical beach locations.

An office is a center of operations where various activities take place, depending on the business conducted. Office conditions determine the credibility and synergy of business entity, as well as the officers' performance and productivity. This study formulates an interior design concept based on the Post Occupancy Evaluation (POE), with Mixed Methods Research (MMR) approach, which emphasizes the empirical meaning based on relevant field data. The research object is the Haleyora Powerindo (HPI) office building in Jakarta. MMR approach ensures the significance level of the work environment quality in the room and the workplace, as well as the officers' performance. The first step was analyzing the spatial conditions in the field based on standardization, which was conducted according to the satisfaction survey of officers. The results show that the work environment quality is high and responds positively. According to the workplace quality, satisfaction is mainly related to workspace area and quality, comfort and style of furniture, circulation, and accessibility to the work table, effectiveness and efficiency of workplace layout, ICT implementation, and HVAC and maintenance. Social space and entertainment facilities provide flexibility in interacting between officers of different divisions that were not in the previous office. Based on the results of multiple regression calculations, the in-door environment (IEQ) and the officer workspace (WQ) quality have a significant effect on officer performance (OP). These are 3 main factors critical in conducting systematic evaluations to obtain results from office space design. This study is expected to be a strategic reference for planning and designing a similar spatial atmosphere in different locations or cases

“…Vernacular houses in coastal areas use wooden walls and exposed brick walls with tile roofs [16]. Vernacular houses in tropical mountains use wooden walls and exposed stone walls with tin roofs [17]. Vernacular house research is essential to find aspects of vernacular houses that can create thermal comfort for residents.…”

Passive thermal comfort has been widely used to test the thermal performance of a building. The science of active thermal comfort is important to be connected with the science of architecture. The currently developing active thermal comfort is adaptive thermal comfort. Vernacular houses are believed to be able to create thermal comfort for the inhabitants. The present study seeks to analyze the connection between the architectural elements of vernacular houses and adaptive thermal comfort. A mixed method was applied. A quantitative approach was used in the measurement of variables of climate, while a qualitative methodology was employed in an interview on thermal sensations. The connection between architectural elements and adaptive thermal comfort was analyzed by considering the correlation among architectural features, the analysis results of thermal comfort, and the Olgyay and psychrometric diagrams. At the beginning of the rainy season, residents of exposed stone houses had the highest comfortable percentage of 31%. In the middle of the rainy season, the highest percentage of comfort was obtained by residents of exposed brick and wooden houses on the beach at 39%. The lowest comfortable percentage experienced by residents of exposed stone houses at the beginning of the dry season was 0%. The beginning of the dry season in mountainous areas has air temperatures that are too low, making residents uncomfortable. The study results demonstrate that adaptive thermal comfort is related to using a room for adaptation to create thermal comfort for the inhabitants.
