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
In the current century, the crisis of meaning and the loss of individual identity underscore the need to focus on self-actualization as a viable solution. Self-actualization is a psychological necessity, and it is crucial to leverage all environmental capabilities to facilitate individuals' self-actualization. This study aims to introduce a causal model for the design components of residential complexes centered on residents' self-actualization. The research was conducted in three phases: 1) document analysis using the Delphi method, 2) a survey-based second phase, and 3) correlation analysis. The study begins with an examination of resources, supplemented by expert insights gathered using the Delphi method, which was chosen for its capability to achieve group consensus through expert judgment. A researcher-made questionnaire was developed for users, and design components effective for self-actualization were identified using R-factor analysis. The theoretical model of the research components was presented, and its validity was assessed using Amos software. The results indicated that the factors influencing the design of residential complexes, based on self-actualization, included Creative Environment, Eventful Environment, Diversity, Collaborative Environment, Interactive Environment, Environmental Safety, and Discoverability. Consequently, it can be acknowledged that a social environment that is safe and secure, where environmental events can occur, and where creative participation is encouraged, can significantly support individuals' self-actualization. This study contributes a novel causal model that elucidates the relationships among the design components of residential complexes, with an emphasis on promoting residents' self-actualization.
