文章根据山西省居住建筑节能设计标准,以太原市实际项目的一栋单体为例,利用pbeca节能软件建立模型,模拟计算出太原市居住建筑在实际工程中的能耗值和节能率,为太原市开展的居住建筑节能设计工作提供了相应的理论基础,对日后太原市的居住建筑节能设计工作具有重要的现实意义。 Based on the energy saving design standard of residential buildings in Shanxi Province and taking a single project of Taiyuan actual project as an example, this paper uses pbeca energy saving software to establish a model to simulate and calculate the energy consumption and energy saving rate of residential buildings in Taiyuan City. Taiyuan city to carry out energy-saving design of residential buildings provide the corresponding theoretical basis for future residential energy-saving design in Taiyuan has important practical significance.
