Abstract:

The practical application effect of ecological energy-saving technologies on the building boundary areas was researched and analyzed using observation data from the Tus-Design headquarters office building renovation project collected over a period of ten years. In order to compare the growth of various plants in various orientations over a 10-year period and the changes in the plants throughout the year, the characteristics of three-dimensional greenery in the building’s four orientations were first investigated. The study finds that, in order to maximize shading performance and energy-saving effects, plant selection should take into account both building orientation and plant characteristics. Deciduous and evergreen plants should also be used together. After measuring the energy-saving temperatures of the vertical ecosystem, double-glazed curtain wall system, and regular glass curtain wall system, the data analysis shows that the vertical ecosystem has a better ability to save energy when put to use. The results of the study show that the three-dimensional greening system has a more pronounced advantage when the outside temperature is above about 27 ℃, especially on the west side. When the temperature is lower than 25 ℃, its energy-saving advantage is less pronounced.

根据启迪集团办公楼项目连续10年的观测数据, 研究和分析建筑边界区域上生态节能技术的实际应用效果.首先, 研究建筑4个朝向的立体绿化植物特性、各种植物在不同朝向10年生长情况的对比及植物在一年中12个月的变化对比, 总结出植物选择搭配应与建筑朝向、植物特性相结合, 落叶与常绿植物搭配使用才能达到较好的遮阳节能效果.然后, 对垂直生态系统、双层玻璃幕墙系统和普通玻璃幕墙系统的节能温度进行数据实测, 结合数据分析得出垂直生态系统在实际使用中可以达到更好的节能效果.研究结果显示:当室外温度在约27 ℃以上时, 立体绿化系统具有较为明显的优势, 尤其在西侧优势更为明显;低于 25 ℃ 左右时, 其节能优势较小.
