Abstract
Buildings have a significant share of global energy consumption and a major role in global warming. Buildings also affect the temperature of their surrounding environment. This paper investigates the effect of Floor Area Ratio (FAR) and urban block configurations on energy consumption, urban microclimate, and outdoor thermal comfort in Tehran with a hot climate, using the simulation method and Ladybug Tools (1.6.0). According to the results, decreasing FAR in an urban block improves urban microclimate while reducing building energy consumption. The results reveal that the effect of FAR on the buildings' energy consumption is more considerable. Decreasing FAR reduces the buildings’ energy consumption and outdoor air temperature. Furthermore, the scattered form of urban blocks consumes the highest cooling energy while having the lowest heating load. The lowest cooling and heating loads are found in the linear and scatter organizations. Considering the dominant cost of cooling energy, the case with less FAR would be the best choice from an economic point of view. For three-story urban blocks, the best case is the courtyard form, while for five and nine-story urban blocks, the best option would be the linear form.

Abstract
The incorporation of various openings that permit daylight into interior spaces significantly influences thermal comfort. In the central region of Iran, Orosi windows are a prevalent architectural feature in courtyard buildings. These latticed door-windows are embellished with colorful glass pieces arranged in geometric patterns. This study aims to evaluate the impact of glass color in Orosi windows on their thermal and daylight performance. The primary objective is to determine the thermal comfort and daylight performance of a typical Qajarian Orosi with different glass colors (colorful, red, blue, yellow, green, colorless) and to identify the optimal glass color for Orosi windows. The findings reveal that the glass color of Orosi windows not only affects thermal comfort but also has a significant impact on daylight performance. Yellow glass offers the most favorable thermal conditions, irrespective of the season. In terms of daylight performance, all glass colors perform adequately; however, the Orosi with yellow glass achieves the highest values for spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE). The next preferred options, in descending order, are colorless, green, and blue glass. Considering both daylight and thermal performance, it is recommended to use Orosi windows with yellow glass due to the 22% improvement in annual thermal comfort and satisfactory daylight performance.

Abstract
Various methods have been employed in vernacular architecture, to achieve energy efficiency in different regions worldwide, especially in facade designs. In Iran, most vernacular buildings are still in use without major modifications and renovations, even in harsh climatic conditions. This study uses mathematical analysis to conduct a quantitative approach toward principles used in the façade design of Bushehr's vernacular architecture. The research critically examined the physical characteristics of eight residential buildings, which were selected as case studies. These parameters included window-to-wall ratios, the surface area for each facade, and the size of different openings concerning height and weight. These physical characteristics of the selected houses were systematically extracted for both the interior and exterior facades, delineating eighteen criteria. The statistical analyses were done using IBM SPSS Statistics version 16.0. The results revealed fourteen linear models—six models related to the exterior facades, five models concerned with interior facades, and three models about the opening. Although the linear models are specific to the vernacular architecture of Bushehr, the research method and approach outlined in this study have the potential to contribute to a framework that can be used by other researchers to uncover underlying principles in vernacular facades elsewhere around the world.
