Abstract
The numerical investigation of computing the rate of radiated solar-energy requires equations as a function of solar-time according to the radiation angle of the sun (β) in the latitude 37°N and the shape. This paper implements the Lagrange interpolation to obtain the equations of normal diagram of elements based on data obtained from surveying. Also the method of Hann-window equation used to estimate the sun path. Albeit, the solar radiation angle effects on the length of element`s shadow on the ground but it is a function of solar-time too. The parameters of the dome traits did compute using the solar-geometry principles in a coexisted function of time to reach a viable equation. The amount of absorbed and wasted energy is presented by analysing its surfaces in the all sides simultaneously. Every single element of BM has been considered to define its especial equation of geometry to analyse their different reactions while transferring energy. Quantitative method of this paper has based on library method of research to define especial equations and field survey to experiment data analysis. According to the mentioned methodology, around 7,54e+4(Kcal.h/m2) solar energy radiate on the BM that its value is equal to around 9,43 (lit/h) energy of gasoil. In other word at least 75,44lit/day fossil energy is saved by the Blue-mosque.

Abstract
The hedonic valuation method has been considered in various fields by researchers in order to estimate the value of a commodity or the demand for exploitation of a commodity for many years. Besides, the hedonic method has been widely used to identify ‘value’ indicators in the housing market. The need for indicators as the key tool for housing planning is related to the need to prioritize planning. Indicators are also critical to understanding housing characteristics. This article tries to develop a "conceptual model" of value by meta-analyzing the existing theoretical literature regarding the valuing indicators in the hedonic model, which has been done by the
meta-analysis method, uses MAXQDA software and open and axial coding to analyze the texts in order to compile and classify the features that explain the value of housing. The research findings, which are taken from 335 highly cited articles between 2009 and 2019, show that despite the long period of application and theoretical development of the model, there is no theoretical consensus on the explanatory indicators of housing value. So, 7 main categories can be identified in the form of 350 concepts and 5883 codes (including frequency), which can show the range of housing value dimensions, in addition to summarizing the issue. Also, the share of basic structural-physical and peripheral categories, with 53.5 and 25.5 percent, respectively, has the most application in the hedonic housing valuation model. In the two-mentioned categories, the share of variables affecting the residential unit, the building of the property, and access to services and land uses with relative shares of 23.6, 19.2, and 16.5%, is more than other variables. The results show that while the concepts of many explanatory indicators of value are the same, a suitable range of explanatory indicators of housing value can be used in the hedonic model according to the goals and the target community, and this can lead to the formation of indigenous and specific values of a society.

Abstract
In spite of the extensive body of research focusing on the concept of "public interest" within the realm of urban planning, there exists a notable dearth in the discourse surrounding the challenges and impediments encountered in actualizing public interest within the context of urban planning and management. The primary objective of this paper is to systematically identify and elucidate the obstacles impeding the realization of public interest within the urban development plans of Iran, offering a theoretical framework to explicate the interrelations among these hindrances. To achieve this goal, an investigation and analysis are conducted on three megamalls situated in Tehran City, serving as representative cases. The principal method employed for data collection is a semi-structured interview, with subsequent analysis carried out through the utilization of Constructivist Grounded Theory (CGT). The outcomes of this inquiry reveal a categorization of barriers into five overarching domains: deficiencies within the urban planning system, conflicts of interest, the legalization of transgressions, a passive civil society, and challenges pertaining to public interest. Each of these categories is expounded upon comprehensively, delving into the nuances of their respective implications. Furthermore, a comparative discussion is presented, drawing parallels between our identified categories and analogous research findings on public interest conducted in various other countries.
