Abstract
Urban morphology, including buildings’ typology and their configuration, affects sky view factor and insolation, which are two of the most influential parameters in urban microclimate. These become even more important in extreme environmental conditions. In this research, challenge was to generate various rule based urban morphologies in a parametric environment. Then, to evaluate them based on mentioned parameters to find the fittest climate responsive morphology. The evaluations are done using grasshopper definitions connected to Ecotect and genetic algorithms in grasshopper in a relatively short computing time. Introducing a high speed and user-friendly environment for designers to introduce forms and evaluate them in several iterations was a main consideration. The tool consists of two parts. First, the generative algorithms to create various rule based morphologies. Second, the analysing algorithms, which find the fittest climate responsive urban morphology based on insolation and sky view factor. As a case study, the program is used on different urban morphologies in Yazd to find the fittest solution. Gaining the maximum sky view factor while having minimum insolation on building surfaces is ideal in hot and arid climate. Anyhow, these two suggest contradicting solutions for urban form. Based on the existing urban fabric in Yazd, various block typologies and their arrangements are generated parametrically. In each scenario, iterations of evaluation find the most suitable ones. After comparing the fittest versions of different types, the most proper building typology, collective arrangement of them and the best orientation are provided as result.

Abstract
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.
