“…On the other hand, for a humid subtropical climate (Chi et al, 2020), the WWR ratio in the north direction is higher than the south direction in general. Concerning the best WWRs, it is recommended 0.39 for NW and 0.4 for SE.…”

“…(Lee et al, 2013b) have recommended that for windows in each orientation should be minimized in all hot regions. For humid subtropical climates (Chi et al, 2020), under the situation of the glazing walls with the same WWR for south window direction intervals, the mean indoor temperatures for SE orientation are lower than the SW orientation.…”

Sustainable aspects of buildings became one of the most crucial aspects of the built environment. The thermal performance can be improved through sustainable design guidelines and, thus, reduce energy consumption. This review covered studies that addressed Window Wall Ratio (WWR) and Window Orientation (WO) and their effect on thermal performance. WWR as a design variable that deals with window design, while the WO as an environmental variable that deals with orientation. The results will help to highlight open issues and research directions in the context of WWR, WO and integrations with other factors in buildings.

“…Research on appropriate WWRs mainly focuses on the influence of WWR on indoor temperature. Chi et al [ 31 ] divided the WWR of traditional houses in Zhejiang into categories of 0.1–0.9 and calculated the indoor lighting, temperature, humidity, and wind speed through software simulation. The range of the three intersecting values is the best WWR.…”

In China, research on winter heating and energy saving for residential buildings mainly focuses on urban residences rather than rural ones. According to the 2018 China Building Energy Consumption Research Report, rural residential buildings emit about 423 million tons of carbon, accounting for 21% of the country’s total carbon emissions. According to the research on China’s greenhouse gas inventory, the main sources of carbon emissions in rural areas are from cooking and the burning of fuelwood and biomass for heating in winter. In this study, the southern Shaanxi area, which is hot in summer and cold in winter, was selected as the research site, and a fire wall system was planned that combines cooking and heating facilities in residential buildings. The system uses the heat generated by cooking and the heat storage capacity of the wall, as well as the principle of thermal radiation and heat convection, to increase the indoor temperature. The advantage is that the hot air generated is mainly concentrated in the inside of the wall, which reduces the direct contact with the cold outdoor air and avoids excess heat loss. In this study, in addition to considering the influence of the cooking fire wall system on the indoor temperature, the difference in the outer wall with or without solar thermal radiation was also considered. The research results show that the use of a cooking fire wall heating system reduces the annual heat load of the building to 440.8318 KW·h, which is a reduction rate of 7.91%. When there is solar radiation on the outer wall, the annual thermal load of the building is reduced by 1104.723 kW·h, and the reduction rate is 19.84%.
