Thermal Performance Simulation of Hydroponic Green Wall in a ColdClimate

The green hydroponics walls are among new kinds of building facades, which receive more attention from architects lately. In addition to the positive effect these walls have in maintaining humidity in arid regions, they also have positive thermal performance in both cold and hot weather conditions. Therefore, they are in the center of designers’ focus for public spaces such as schools. In terms of soil-free cultures, these walls are of three general types: wide, horizontal, and vertical. The use of different types of green walls in each zone allows for different thermal performance. This paper aims to investigate the thermal performance of hydroponic green walls in different facades of green school in term of thermal performance. Moreover, the present study only addresses green schools in cold climates. We conducted a simulation by using Energy Plus software with three different types of hydroponic green walls in Shahrekord city of Iran, which were monitored in 20 years" from2000 until2019".The thermal performance of each type was analyzed and compared with other samples. Finally, the best kind of green- hydroponics wall with the best thermal performance was identified for each wall.
