中文摘要:

      随着人们对室内环境要求的提高，我国农村住宅建筑（简称：农宅）的能源消耗逐年增加。为减少农宅能耗，降低二氧化碳排放，满足节能需求，提出一种附加阳光间的被动农宅形式。通过EnergyPlus对该附加阳光间农宅进行了分析，获得了其采暖期的建筑能耗，研究了附加阳光间玻璃层数、填充气体及空气层厚度等因素对农宅能耗的影响，并优化了附加阳光间的玻璃结构。研究结果发现，与传统农宅相比，在农宅南侧附加阳光间，可减少建筑采暖能耗1115.64 kw·h。双层玻璃内填充气体种类和空气厚度对建筑能耗影响较大。其中，填充氪气时建筑能耗最低，空气层厚度9mm时建筑节能效果最好。

英文摘要:

      With the increase of people"s requirements for indoor environment, the energy consumption of rural residential buildings (referred to as farm houses) in China has increased year by year. In order to reduce the energy consumption of farmhouses, reduce carbon dioxide emissions, and meet energy-saving needs, a passive farmhouse form with additional sunspaces is proposed. EnergyPlus analyzed the farmhouse with additional sunspace and obtained the building energy consumption during the heating period. The influence of factors such as the number of glass layers, filling gas, and air layer thickness on the energy consumption of the farmhouse was studied and optimized the glass structure with sunspace. The results of the study found that compared with traditional farm houses, the sunspace on the south side of the farm house can reduce the building"s heating energy consumption by 1115.64 kw·h. The type of filling gas and the thickness of the air in the double-layer glass have a greater impact on the energy consumption of the building. Among them, the energy consumption of the building is the lowest when filled with krypton, and the energy efficiency of the building is the best when the air layer thickness is 9mm.
