“…homes is affected by convenience in use and affordability of the adaptation methods to achieve thermal comfort [6]. Similar inferences were drawn by Indraganti and Uno et al for Indian and Indonesian residences respectively [7,8]. Kim et al [9] concluded from their Australian residential study that the availability of adaptive strategies and occupant's attitude affected the decision of using air conditioners (ACs) whereas Song et al concluded education and income to be the significant factors affecting such decisions in Chinese households [10].…”

Thermal adaptation in low-income housing of Mumbai, India is investigated using a longitudinal field study and in-situ field measurements. 705 set of responses from two different neighbourhoods were analysed to understand the patterns of behavioural adaptation. Spatial configuration, temporal factors and underlying societal norms influenced the comfort-related behaviour in low-income housing. Clothing adaptation was primarily governed by the gendered socio-cultural practice of purdah system and western influences rather than thermal needs. Logistic regression predicts probabilities of 88% and 20% for using ceiling fans and exhaust fans respectively at 80% indoor air relative humidity. However, thermal stimuli cannot predict occupant behaviour well due to presence of non-thermal determinants. Security, privacy, environmental nuisances (dust, noise and odour) and insects or animals menace (mosquitoes, monkeys, rats, lizards) were the major barriers to thermal adaptation. The study is helpful in evaluating the influence of occupant behaviour on building performance and thus to inform building design and operation. The policy implications could be through the development of design guidelines for the housing schemes to create thermally comfortable low-income dwellings.

“…First, as noted by Nugrahanti et al [7], the overall plan of the building was created based on a typological analysis of existing middle-class residences, specifically Rusunami. Second, the building's concept for passive cooling is based on the findings of several pertinent studies, including those that looked at Dutch colonial buildings [8], middle-class apartments in Indonesia [9], vertical void space [5,6], and radiant floor cooling systems using phase change materials [10].…”

Experimental study on vertical void for improving natural ventilation in midrise double-loaded apartments

Affordable apartments in tropical developing countries generally have double-loaded corridors to maximise the total floor areas. Building designs with double-loaded corridors often suffer from poor environmental conditions. Passive design using a vertical void can help improve the natural ventilation in the such building design. This study investigates the effectiveness of vertical voids in enhancing the wind speed in the building. An experimental building with a vertical void, open pilotis, penthouse at rooftop and wind fin on the ground floor to help direct air to the void was constructed in Tegal, Indonesia. Five cases were considered by controlling the window openings, louver openings on the roof and change in fin size at pilotis. Wind speed and direction were recorded at one-second intervals. High wind speed was experienced in the pilotis and void when the wind direction is from the north and the wind speed in the void improved due to the wind fin being placed on the south corridor of the building. The results show the average wind speed in the void is twice as high as compared to the corridors. The building design performed best with high wind speeds in the void and corridores when all windows were kept open.

“…Vernacular or traditional architecture are designed to respond strongly to the surrounding environment and help to promote comfort and sustainability in the building. However, with economic growth, new technology and changing of lifestyle, the style of housing has been changing dramatically [9]. This new architecture evolution also raises questions on the thermal performance of the building as well.…”

“…As an example, residential building that have been built in Phnom Penh between 2000s until now are more focused the aesthetic and the construction budget than on the comfort that the building would provide to occupants. The rate of using air conditioner is 15% in Phnom Penh and with economic growth, it is expected to increase rapidly in the near future [9]. In Cambodia, the major use of electricity in each household in the urban area is cooling energy of air-conditioning [10].…”

Comfort of the building is one of the important factors that is hard to achieve for architects and engineers as it depends on both physic and psychological parameter. This paper discusses these two aspects on the thermal performance of residential building in context of hothumid climate. Three different types of residential buildings including townhouse, detached house and apartment building in Phnom Penh, Cambodia were chosen as the case studies. The analysis of thermal performance of each house is based on (a) the measurement of physical parameters (air temperature, relative humidity, air velocity), (b) occupants survey to compare with data from the measurement and (c) interview with the occupants to know about their satisfaction and sensation to the physical parameters. Impact of different designs of houses on thermal performance and the importance of influential physical parameters for tropical climate is analysed. Comparison of results to the Fanger’s model also indicate the importance of air velocity in thermal comfort for tropical region. The survey shows that in natural ventilation, women in their 20s to 30s feel comfortable with the temperature of 29 to 30°C and humidity of 73 to 75%.
