竹编夹泥墙节能优化研究--以重庆市大足区某起居室为例

Research on Energy-Saving Optimization of Bamboo Plaiting Mudwalls:A Case of a Living Room in Dazu District of Chongqing

在美丽乡村与可持续发展背景下,传统材料的生态价值日益突出。在传统低技的营造策略下,对墙体进行节能优化,将有助于“双碳”目标的实现。研究以竹编夹泥墙为例,通过生土改性与构造优化,提高墙体节能效果。项目基于PKPM-Energy建筑能耗分析软件,将参数设置为重庆市大足区某带有空调采暖的起居室,对包括两种改性墙体在内的五个墙体样本进行能耗模拟。发现带有空气层与外保温层的改进墙体节能效果最佳,相较于节能烧结空心砖每年可节能382.15 kW·h。

In the context of“beautiful countryside”and“sustainable development”,the ecological value of traditional materials has become increasingly prominent.Under the traditional low-tech construction strategy,the energy-saving optimization of the walls will contribute to the realization of the carbon peaking and carbon neutrality goals.The paper takes the bamboo plaiting mudwall as an example,and improves the energy-saving effect of the wall through soil modification and structural optimization.Based on the PKPM-Energy building energy consumption simulation tool,the project sets the parameters as a living room with air conditioning and heating in Dazu District,Chongqing,and simulates the energy consumption of five wall samples including two modified walls.It is found that the improved wall with air layer and external thermal insulation layer has the best energy-saving effect,which can save 382.15kW·h per year compared with energy-saving fired hollow bricks.
