“…Research has shown that, in the cold areas of the Shandong region, an increase by every 0.01 in the shape coefficient of buildings on the basis of 0.3, building energy consumption will increase about 2.4%-2.8%. As the shape coefficient reduces by each 0.01, energy consumption will be reduced by 2.3%-3% [17], hence the building energy consumption of rural houses in the research region are generally high. provides some theoretical and technical references and values for the reconstruction work in other areas.…”

“…When a building is designed, the shape coefficient refers to the ratio between its external surface and the total constructed volume. The smaller the shape coefficient is, the smaller the heat dissipation area shared by the unit building space, which causes less energy consumption [17]. Zhao pointed out that the shape coefficient of rural houses shall have a certain influence on building energy consumption and indoor thermal environment, and the shape coefficient should be minimized [18].…”

With the continuous implementation of a plan for reconstruction of “Beautiful Countryside” in China, the rural environment and appearance of rural houses have been significantly improved. However, those houses in cold areas of China have great trouble with indoor temperature and heating-related energy consumption. After investigating the current situation of the layout, building envelope, indoor temperature, and energy consumption of the rural houses renovated by the plan of “Beautiful Countryside” in Shandong Province, this paper puts forward the improvement measures of raising indoor temperature and reducing energy consumption. On this basis, a typical rural house was selected, and DesignBuilder was utilized to simulate the effects before and after the application of different renovation measures for this house. The results show that the main way to raise indoor temperature and reduce energy consumption is to improve the thermal insulation performance of the building envelope, including renovation of the roof, exterior walls, doors and windows, and attached sunspace. In addition, combined with the achievements of “Beautiful Countryside” reconstruction, this paper shall propose specific renovation practices which are suitable for different rural houses. Based on the level of economic development in rural areas, it also puts forward some feasible renovation paths for different rural areas, and further provides references for other areas to carry out relevant work in the future.

“…Based on the literature review and extraction of passive strategies commonly used in hot summer and cold winter areas, our research team screened the passive design parameters that are relatively important to building energy consumption, including building orientation (BO), sunroom depth (SD), overhang depth (OD), courtyard size (CS), window-wall ratio (WWR), window heat transfer coefficient (WHTC), external wall heat transfer coefficient (EWHTC) and roof heat transfer coefficient (RHTC). 34,[36][37][38][39][40][41] Since the focus of this study was the transformation of traditional dwellings, passive design parameters such as BO and CS are not applicable to the renovation of old buildings. As a result, the selected six passive design parameters suitable for this research are SD, OD, WWR, WHTC, EWHTC and RHTC.…”

Traditional dwelling has achieved harmony between building and climatic environment, which is one of the most significant prerequisites for sustainability. In this study, Liyuanba traditional dwellings were selected as the representative traditional dwellings in southwestern part of Qinba mountainous area, and passive design strategies extracted from traditional dwellings were utilized to improve its indoor thermal comfort. This research presents an approach in which the energy simulation, orthogonal arrays and range analysis were integrated to analyze the sensitivity of each passive parameter to overall energy-saving performance and to determine how energy consumption can be minimized by the optimal combination of them. The optimized passive strategy could reduce the annual energy consumption of the simulated dwelling by 65.1% compared with that of the original one and increase the indoor air temperature and mean radiation temperature by 4.31°C and 4.35°C in winter, respectively, meeting the requirements of the design standard for energy efficiency for rural residential buildings (GB/T50824-2013). Through the systematic study of passive parameters in the southwestern part of Qinba mountainous area, the optimal combination of passive design strategies could be utilized for the renovation of traditional dwellings to improve the building energy performance under the premise of satisfying the indoor thermal comfort.

“…In response to the cold winter conditions in Zibo, Shandong, the green farmhouse adopts a compact collective layout, integrating the various functional rooms scattered in the courtyard in the traditional layout mode into one block. This block has two layers and the depth of the space is moderately increased, which form is approximately a square shape, unnecessary bump changes on the shape are avoided, and the shape factor is minimized as much as possible [5]. The roof form is a sloping roof, which continues the traditional rural style while adapting to the cold winter weather conditions (Figure 2).…”

With the vigorous promotion of the development and construction of “beautiful countryside” in China, the irrationality of the functional space of rural farmhouses and the energy conservation and consumption reduction of farmhouses have become urgent problems. In this paper, the design practice of a green agricultural house with prefabricated steel structure in Shandong province was taken as an example. Based on a variety of factors such as environmental characteristics, regional characteristics, and technical conditions, design and application research were conducted from the aspects of building shape and functional space design, appropriate green building technology. What’s more, the energy consumption simulation software was used for its quantitative analysis of energy saving effects and indoor temperature, and a green farm house design strategy adapted to the characteristics of cold climate, regional characteristics, and future development trends was discussed, which was intended to provide a technical reference for the construction of beautiful countryside.
