Saving and optimizing energy saving solutions to reduce biological pollution while achieving more comfort in the workplace and in life has always been the focus of the attention of energy industry thinkers. Envelopes is one of the most effective structural components of a building in energy consumption; therefore their behavior under different climatic That is why it is high. In this study, the effect of form paramter on dynamic behavior of a kind of building envelopes that are multifaceted envelopes, is studied in the climate of Tehran. One of the reasons for choosing multidimensional envelopes for the subject matter for this research, is the evaluation of the thermal performance of buildings with a digital pattern, which in the last few decades is due to the development of design tools in the field of algorithmic and parametric domain designers. The research method used in this collaborative strategic research, includes library studies and simulations. For this purpose, we obtained from the library resources and the literature review of research simila, to the variables used to construct some basic forms. 17 different forms for the southern crust were considered as a non-laboratory space with an area of 40 square meters, each of which developed nine modes with a change in the parameeter of the size and deviation of the flat form in the Grasshopper software. Then, 153 forms, were compared with each other and with the base envelope, in the part of annual solar radiation, annual cooling consumption, annual heating consumption, annual electricity consumption for artificial lighting, annual production of electrical energy through the solar cell panels embedded on On the shells and the distribution of natural light in the interior space. In addition, in each part, the effect of the form parameters such as geometry, layout of the repeating pattern, size, segmentation, surface area-to-volume ratio, window status in terms of quantity and quality, the area of the southern surfaces, etc. were investigated. The results indicated that the annual solar radiation for the 153 states was considered to be higher than the baseline, and this has been repeated in relation to the area of the southern envelope, and in all cases, as compared to the base form, the increase of the southern levels is observed. In calculating the annual cooling load of 153 multifaceted envelopes in comparison with the base form, the formation of surface to volume in some cases reduced the cooling load of the room under study and in some cases increased it. Reducing the cooling load was measured in best case up to 4% and increasing the cooling load in worst case was measured up to 48%. In the meantime, forms that, while becoming multidimension, increased the southern surfaces area at the lowest possible level, had better cooling performance. The results of the annual heating load showed that the transformation of the flat envelope into the multifaceted envelope, can not have a positive effect on the heating energy consumption of the building. From the results of the amount of charge used to provide artificial lighting, it was found that, this value in all 153 examined states, in the best case of energy consumption in the electrical sector, was increased 3.2 percent, and in the most critical mode, increased by 235.3 percent, due to the deviation of the window angle from the vertical to the down, up, east or west, as well as the decrease window area. Also, in comparing the total energy consumption in only two cases, we saw a decrease into the base form, which was calculated to be about 1%, but considering the capability of the Prismatic surfaces of these envelopes, in the production of electrical energy by solar panels, In 93.5% of the examined forms, we see a decrease in energy consumption up to 57% compared to base form. In fact, in many forms, becoming envelope multidimension has led to an increase in energy consumption, and power generation by photovoltaics panels has offset this increase in energy consumption and has made them less cost-effective than base form. However, it is evident that less energy consumption is more important than energy production in the first place. In this way, choosing the optimal multidimensional envelope, examining the simultaneous energy production and energy consumption, along with the cost of running such envelopes, will be important, that today, with the advanced software capabilities, it is possible to estimate the cost of prismatic buildings.
