A study on influencing factors of optimum insulation thickness of exterior walls for rural traditional dwellings in northeast of Sichuan hills, China

Research on energy-saving factors adaptability of exterior envelopes of university teaching-office buildings under different climates (China) based on orthogonal design and EnergyPlus

“…The computational process of EnergyPlus is based on the integrated processing of multi-program modules [ 65 , 66 ] whose core is the basic heat balance principle, it can be simplified as Eq. (9) [ 21 , 28 ]. …”

“…Braulio-Gonzalo [ 27 ] and Hou et al. [ 28 ] optimized the thickness of the insulation material by utilizing an economic evaluation to balance the demand and cost of the building environment. Yu et al.…”

“…A more accurate and reliable optimization conclusion can be obtained with a fewer number of experiments after using an orthogonal design, and it allows for performing both range analysis (R) and analysis of variance (ANOVA) to evaluate test results. There is growing interest in the use of orthogonal design methods for optimization in various fields [ 28 , 51 , 52 , 53 , 54 , 55 ]. Therefore, a university teaching-office building was researched in this paper through orthogonal design and numerical simulation (EnergyPlus) to explore the adaptability (including the optimal parameters and influence degree of each factor of the envelope and the significance levels) of the energy-saving factor of the building envelopes under different climates, which aims to provide the optimal solution for the renovation of university teaching-office building envelopes under different climatic conditions in China to achieve maximum energy-saving building operations.…”

“…As a result, more and more researchers and engineers have realized that the energy-saving performance of buildings can be improved by improving the envelope configuration. Braulio-Gonzalo [27] and Hou et al [28] optimized the thickness of the insulation material by utilizing an economic evaluation to balance the demand and cost of the building environment. Yu et al [29] conducted an energy simulation of three exterior wall insulation systems by using DesignBuilder and pointed out that the insulation effect was not only related to the insulation thickness but also the insulation form.…”

Indoor thermal comfort in a rural dwelling in southwest China

“…The thermal environment is influenced by various factors, such as wall materials ( 16 – 19 ), the outdoor environment ( 20 – 26 ), and active equipment ( 27 , 28 ). Numerous locations have devised new construction and renovation solutions to alter the indoor thermal environment of dwellings by changing the above factors ( 29 – 31 ). However, in the rural areas of developing countries, the application and promotion of these (perhaps expensive) design and construction techniques are limited because of poor architectural design technologies and underdeveloped economic conditions ( 8 ), thereby posing severe threats to the indoor comfort and health of rural dwellers.…”
