摘要
本文应用Design Builder软件模拟了不同地区、墙体类型以及窗墙比条件下,某三层办公建筑外立面应用垂直绿化技术的节能效果。模拟结果表明,外立面应用垂直绿化技术可以有效提高外墙整体的热性能,夏季垂直绿化墙相对普通砖墙节能5%-15%,而冬季节能节能量较小。对于保温性能较差、窗墙比较小的建筑,垂直绿化的节能效果更加显著。另外,夏季负荷较大的气候区,垂直绿化墙节能效果较好。
Energy-saving effect of vertical greening in a three-tier office buildings in different regions, different types of wall and window to wall ratio condition, were simulated with DesignBuilder sottware. The simulation results show that the application of vertical green facade can effectively improve the overall thermal performance of external walls. It is relatively common that green wall can save 5% -15% in summer, but it can save less energy in winter. For a building with poor insulation performance and small window to wall ratio, energy-saving effect is more significant by using vertical greening. In addition, vertical greening is a good method of energy saving in district of greater cooling load.
