This study focuses on the thermal behaviour of a building prototype equipped with an evergreen green façade. The results of a two-year experimental campaign carried out under Mediterranean climate conditions are presented. Heat fluxes in the green covered wall and in the bare wall were analysed. Their comparison allowed finding out the energy saving, in terms of heat flux reduction through the wall, obtained through the use of the green façade. The energy benefit was evaluated throughout the year, differences between warm and cold periods and between times of day were pointed out. In the warm periods, energy saving was recorded mainly at daytime, while in the cold periods at night-time. The evergreen green façade allowed remarkable energy saving in wintertime as well. The monthly mean energy saving resulted equal to 8.19 MJ m⁻². The maximum benefit was achieved in July, 17.24 MJ m⁻², while the minimum in January, 2.33 MJ m⁻². The green façade provided an annual energy saving equal to 28.5 % compared to the un-vegetated wall.

这项研究的重点是配备常绿绿色立面的建筑原型的热性能。介绍了在地中海气候条件下进行的为期两年的实验活动的结果。分析了绿色覆盖墙和裸墙中的热通量。通过他们的比较，可以发现通过使用绿色立面减少通过墙壁的热通量方面的节能效果。全年评估能源效益，指出温暖和寒冷时期之间以及一天中不同时间之间的差异。在温暖时期，节能主要在白天记录，而在寒冷时期则在夜间记录。常绿的绿色立面在冬季也可以显着节约能源。月平均节能结果等于 8.19 MJ m^-2。7 月份的效益最大，为 17.24 MJ m ^-2，而 1 月份的效益最低，为 2.33 MJ m ^-2。与没有植被的墙壁相比，绿色外墙每年可节省 28.5% 的能源。
