The essential part of any shading device is to intercept the solar radiation in such a manner that it allows enough daylight inside the building, while at the same time the indoor thermal comfort is upheld for all the seasons. Earlier studies proved that in comparison with internal shading devices, the external ones minimize the internal heat gain in an effective manner by blocking the radiation, before it reaches the fenestration glazing. However, fixed external shades are incapable of balancing the varying requirements of light and heat for different climatic conditions. Mainly, summer and winter in the composite climate demands adaptive shading solutions as per the changing season. The current study is an attempt to evolve appropriate external adaptive louver shades and recommend louver angles for different months, for a single space of a typical apartment building in Delhi NCR region. The recommended angles allow the occupants to make informed decisions by manually adjusting the louvers to improve the indoor environment. This study utilized ladybug and honeybee plugins for the purpose of simulation. The results show that the monthly adjustments of external adaptive shades enhance the indoor environment and save energy. The study developed, analysed and compared two different types of external adaptive louver shading systems such as EALS (External Adaptive Louver Screen) and EALA (External Adaptive Louver Awning) for better indoor environment and energy saving for west orientation.

“…Recently, Sakhare and Ralegaonkar (2017) established a strategy to regulate indoor temperature in slum dwellings under renovation, with the goal of enhancing building planning and suitable material selection while keeping costs under control in contrast to current practices. Singh and Chani (2017) investigated the influence of various factors, including gender, age, subject's exposure to roof heat and season and thermal sensation in multi-story apartments. Like studies in Hyderabad, Kumar and Singh (2019) carried out a thermal comfort study in 12 NV hostel buildings in Jalandhar and Jaipur.…”

Purpose Science mapping is an essential application of visualization technology widely used in safety, construction management and environmental science. The purpose of this study was to explore thermal comfort in residential buildings (TCinRB) research in India, identify research trends using a science mapping approach and provide a perspective for recommending future research in TCinRB. Design/methodology/approach This study used the VOSviewer tool to conduct a systematic analysis of the development trend in TCinRB studies in India based on Scopus Index articles published between 2001 and 2020. The annual numbers of articles, geographical locations of studies, major research organizations and authors, and the sources of journals on TCinRB were presented based on the analysis. Then, using co-authorship analysis, the collaborations among the major research groups were reported. Furthermore, research trends on TCinRB studies were visually explored using keyword co-occurrence analysis. The emerging research topics in the TCinRB research community were discovered by analyzing the authors’ keywords. Findings The findings revealed that studies had been discovered to pay more attention to north-east India, vernacular architecture, Hyderabad apartments and temperature performance in the past two decades. Thermal adaptation, composite climate, evaporative cooling and clothing insulation are emerging research areas in the TCinRB domain. The findings summarized mainstream research areas based on Indian climatic zones, addressed current TCinRB research gaps and suggested future research directions. Originality/value This review is particularly significant because it could help researchers understand the body of knowledge in TCinRB and opens the way for future research to fill an important research gap.

“…Especially for the elderly, their ability to adapt to thermal environment declines with age. 40,41 This is likely to be the major reason for the increased sensitivity of roadside residents. Nearly all the interviewees stated that they were dissatisfied with their acoustic environment to varying degrees.…”

The acoustic environment in an urban dwelling is a key factor in human health, especially in megacities, where there are high levels of traffic noise. This study investigated the effects of various socio-economic indicators (gender, age, roadside residence, average daily time at home) on the subjective evaluation of residential acoustic environments, employing a series of questionnaire surveys and in-depth interviews in two Chinese megacities (Chongqing and Guangzhou). The findings indicate that residents in Chongqing, a typical mountainous city, are less satisfied with their acoustic environment than those in Guangzhou, a city built on a plain. However, there were no significant differences between residents in the two Chinese megacities in terms of their perspectives on their thermal, humid or luminous environments or noise-related health symptoms. Regarding perceptions of acoustic environments, there were significant differences between residents in the mountainous city and the plain city, as well as those in roadside and non-roadside homes, but no significant differences were identified between the views of men and women or the young and the old, and time spent at home appeared to have no impact. Moreover, age and average daily time spent at home are likely to be associated with noise-related health symptoms.
