“…Most underprivileged people residing in inland in mountain slopes uses the residence type with zinc roof and earth fl oor. This matches the fi nding which shows that rural residences can create thermal comfort [23]. Zinc roof is deemed capable of conducting high heat since it is also a conductor metal.…”

A building's ability in creating thermal convenience will produce energy saving. Such an ability of a building is known as building thermal performance. Building thermal performance is highly infl uenced by the building envelop and environment temperature. This research aims at analyzing the thermal performance of two wood-and exposed stone-walled buildings in mountainous areas. The measurement uses a scaled prototype of 0.60 m x 0.60 m x 0.60 meter size. Determination of building materials in accordance with local material conditions results from previous studies. The roof uses four material variations, namely roof tiles, zinc, asbestos and thatch. The fl oor uses three material variations, namely earth, concrete rebate and ceramic. There are a total of 32 building envelope variations. The measurement is performed for 24 hours for each variation model. The analysis uses a graphic and it will shows the difference between wood-and exposed stone-walled buildings. The research results generally show that air temperature inside wood building is higher than in exposed stone building. The highest indoor air temperature difference between the wood building and the exposed stone building is 0.37 o C. Finally, the building variation with the highest thermal performance is the one with zinc roof and earth fl oor.

“…Specifically, Shao took advantage of TRNSYS to simulate the temperature of rural houses in Dalian, and the results showed that the window/wall ratio in the south of rural houses had a great impact on the indoor temperature, so the window/wall ratio in the south should be adjusted if able [22]. Lu also exploited TRNSYS and EnergyPlus to optimize the shape and building envelope design aimed at the rural houses in areas with hot summers and cold winters [23,24]. Hu utilized DeST to explore the influence of different building forms on energy consumption, and it turned out that the shape of rural houses in Beijing should be as simple and compact as possible to ensure the smaller shape coefficient, thereby reducing energy consumption of buildings [25].…”

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.

“…Over the past few years, many important studies have investigated the energy efficiency of a building, in particular paying attention to indoor thermal comfort [24,[36][37][38][39][40][41][42][43][44][45][46][47][48][49][50]. Many researchers have conducted simulations that were coupled with optimization methods.…”

This paper presents a comparative analysis of the carbon footprint, energy demand and life cycle costs of a model of a building located in the Central Europe climate zone. One specific example—the quantitative differences in global warming potential, life cycle costs and thermal comfort—has been shown, depending on the different construction (wood, brick) and heat sources used; traditional and energy-saving solutions have been considered. The research was carried out using the EnergyPlus simulation program for a multi-zone model of a naturally ventilated single-family house. Calculations were made for a 25-year life cycle using the standard climate data for Warsaw (Poland). The real occupancy schedule of the individual rooms was adopted and the instantaneous ventilation airflow was modeled, and its intensification due to the additional opening of windows was optimized. An estimated budget of the entire structure of the building and the heat sources was used for the cost analysis. The research has succeeded in developing some general conclusions and guidelines and recommendations for both the investors and designers of energy-saving and environmentally friendly houses. Considering the most economical an ecological solution, wooden houses are better than brick houses. In the wooden building, however, there are a larger number of thermal discomfort hours.
