Abstract

Since the energy consumption has become one of the crisis of modern buildings, modeling the Iranian past architecture patterns could be helpful. The shopping streets as one of the main sectors consuming energy locate near the open spaces it seems, therefore, they need more thermal comfort. However, using passive techniques, the Iranian traditional bazaars architecture solved the problems regarding thermal comfort. The present inquiry aimed at investigating thermal comfort of traditional and modern commercial buildings from the perspective of solar radiation to compare traditional structures (with traditional design and materials) with modern ones (with modern design and materials). Therefore, Vakil (traditional) and Mollasadra (modern) Bazaars (with the same orientation), located in Shiraz with a semi-arid climate,  have been chosen. Vakil bazaar situated in historical context of city and Mollasadra situated in the first modern part built in 1980. A naturalistic approach was applied to investigate the relation between shadow on surfaces, shopping load and cooling needed in summer and the relation between the solar radiation on surfaces, shopping load and heating load in winter first, a number of questionnaires were used to survey 120 samples including both customers and shopkeepers to show the relation between shopping load and cooling or heating need second, Ecotect Analysis 2011 was employed to simulate surfaces with shadow and solar direct radiation in winter and summer to evaluate the relation between the surfaces received shadow and heating or cooling need. The results showed that along with a full shade in summer, the customers of Vakil Bazaar are interested to do shopping almost in all hours since there is no obtrusive solar radiation in contrast, customers of Mollasadra Street experienced a shadow from sunrise to 11:00 in summer morning thus 73.3% of customers in Mollasadra made complaints about the existing shadow since there is no shade in crowded shopping hours and points especially in summer afternoon furthermore, 93.3% of shopkeepers in Mollasadra used cooling and heating equipment which demonstrate congruently of orientation and quality in sunshades with climate. At the end, some suggestions regarding the mentioned problem in Mollasadra have been proposed.

Abstract
In the noble verses of the Quran and the traditions of the Prophet Muhammad (pbuh) and the Imams, multiple references have been made to places of worship, education, and residence. On the other hand, religious texts have extensively discussed light and its concepts. Architecture has long been a manifestation of sublime human emotions and a platform for the realization of human excellence. It creates a perceptible space that leads individuals to contemplation. Therefore, this article focuses on the assessment of daylight in the combined pattern of mosque-school-residential buildings, in one of its exceptional case studies, the Mansouriye Traditional Seminary in Shiraz. Daylight was evaluated based on indicators of illuminance, daylight factor, and light penetration depth on the first day of 22 December from 8 AM to 5 PM. The data for each component was collected in the selected southeast direction of worship, educational, and residential spaces using measurement methods (lux meter device), numerical calculations (Olgy formula), and geometric calculations. The data was then analyzed using two quantitative comparative methods with the standard of LED and the Iranian Lighting Design Association, and a qualitative analysis method. The results indicate satisfactory utilization of daylight in the studied space within the functional time frame of Islamic-Iranian architecture. The illuminance intensity in the mosque does not meet the standard. However, this indicator ranges from 200 to 500 lux in the school and from 150 to 500 lux in the room, aligning with the specified standards. The daylight factor in the place of worship does not have the standard, while it ranges from 2 to 5 percent in the school and in the room until 11 AM remain within the standard.

Identifying The Social-Climatic Expansible Housing With Emphasis on Family Growth (Case Study: Hamadan City)

Volume 12, Issue 1 (3-2024)
Abstract
The model of housing based on the religion of Islam in order to create a residence and obtain peace for the family depends on responding to their fixed and changing needs. Considering that the housing body is a container in which the family community is formed, the need to adapt the housing to the growth of the family as changing needs and respond to it over time in order to achieve the stability of the family community is important. In the meantime, the "expansibility" can be effective in climate stability in addition to social stability by making adaptations or changes in housing components according to the changing needs of residents. Given the high consumption of fossil fuels, designing and constructing residential buildings compatible with the climate is essential in order to reduce energy consumption. In fact, the use of private courtyards on the floors of residential units, in addition to creating a platform for the development of building walls, helps to provide light to the interior spaces and control the climatic conditions. The aim of the present research is to identify the optimal model of social-climatic expandable housing that is suitable for the growth of the family. In this way, the research question was formed in search of a housing model that, in addition to the expandability of the housing components in the courtyard of the apartment, also provides climate efficiency. This article focuses on the topic of social sustainability in housing by examining the expansion of its components in the courtyard of the apartment and it also addresses the topic of climate sustainability by assessing the amount of radiation received by expansible walls in the courtyard. The use of both qualitative and quantitative methods to identify the social-climatic expandable housing pattern has led, in the first stage, to the presentation of the expandable patterns A, B, and C in the courtyard of a residential apartment. Then, based on quantitative methods with simulations of the patterns in EnergyPlus software, the optimal pattern was identified. As the main result of this research, by comparing the amount of radiation received from the south, east and west in the cold, moderate and hot months of the same direction units, the best units in the SW direction belong to building B, in the NE and NW direction belong to building C, in the SE direction It belongs to A and C buildings.​
