Abstract: 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.

Abstract: A comprehensive critical examination of China's folk architectural forms. Together with its companion volume, \"China's Living Houses: Folk Beliefs, Symbols, and Household Ornamentation\", it provides a study of the environmental, historical and social factors that influence housing forms for nearly a quarter of the world's population. Both books draw on the author's 30 years of fieldwork and travel in China, as well as on published and unpublished material in many languages. The work begins by tracing the interest in Chinese vernacular buildings in the 20th century. Early chapters detail common and distinctive spatial components, including the interior and exterior modular spaces that are axiomatic components of most Chinese dwellings as well as conventional structural components and building materials that are common in Chinese construction. Later chapters examine representative housing types in the three broad cultural realms - northern, southern and western - into which China has been divided. Knapp completes his survey with an exploration of China's old dwellings in the context of the rapid economic and social changes that are destroying so many of them.

TL;DR: In this article, the authors evaluated the thermal performance of six modern institutional and office buildings in warm-humid, hot-dry and composite climate zones, and compared performance using temperature gradients overlay on wall sections, heat maps and linear regression analysis to understand the relationship between the outdoor and indoor conditions to determine the nature of climate responsiveness of each building.

...Daytime ventilation was achieved by opening all of the windows from 8:00-20:00 and closing them from 20:00-8:00 to emulate the window opening behaviour of the household that was observed in the previous survey (Kubota et al., 2009)....

...This effect is well known in high thermal mass buildings that are ventilated at night (Kubota et al., 2009), and it is interesting to observe this effect even with the open courtyards that were located nearby such as the living rooms....
