Abstract
In recent years, optimizing the energy consumption of buildings has become one of the important environmental and economic goals in sustainable architecture and urban planning. A group of factors affecting the energy consumption of buildings is their physical characteristics and form. In this regard, in the present research, the effect of volumetric porosity in high-rise buildings on their energy consumption has been investigated. The purpose of this research is to explain the correlation between the volumetric porosity of a building, as an independent variable, and its cooling and heating load, as a dependent variable, in a high-rise residential complex in Tehran. In this regard, first, a modular-generative model has been created in the Grasshopper plugin of Rhino software, which can create a porosity of 0 to 50% parametrically. Then, the cooling and heating load of each of the produced models in the city of Tehran and on the June 21 (summer solstice) and December 21 (winter solstice) were calculated using the Honeybee plugin, with standard settings. The data obtained from the simulation were entered into the SPSS software environment and the correlation test of the percentage of volume porosity and energy consumption was performed on the two aforementioned dates in Tehran. In order to validate the research method, this process was performed in 3 other climatic zones of Iran and the findings were compared with other studies in this field. The results of this research showed that the increase in porosity, assuming the number of modules is kept constant (the total volume of the building remains constant) and the site coverage ratio - as is common and inevitable in high-rise buildings - have a significant positive correlation with increased energy consumption in high-rise residential buildings in Tehran.

Abstract
Any scientific activity or instrumental application involving façades—such as research, design, evaluation, and decision-making—requires a comprehensive set of criteria to cover all expected requirements. This highlights the necessity of a study to explore, gather, and organize a holistic set of criteria for the evaluation, study, design, and decision-making regarding façades. Moreover, establishing a comprehensive list of criteria is essential but insufficient on its own. It is equally important to achieve a mutual understanding of these criteria, providing experts and researchers with a common language and understanding regarding façades. Although various criteria have been mentioned in different façade-related research, a summary study to gather, organize, and reliably define these criteria is needed to improve the logical applications of façades and facilitate mutual understanding. This study aims to take the first step in meeting this requirement by describing each criterion relevant to façade assessment. In this context, a systematic library-based research approach was employed, reviewing 71 related papers. Criteria were then extracted using an exploratory study based on open and axial coding methods. Ultimately, 42 criteria were identified and organized into five primary categories: environmental aspects, social impacts, economic aspects, efficiency and effectiveness, and technical aspects.
