Bioclimatic condition is the most important factor that affects the quality of human life, architecture and housing. Lastly, results in bioclimatic design that presents valuable solutions for reducing energy consumption in the building sector while providing thermal comfort.
This paper aims to evaluate the thermal human comfort of bioclimatic conditions according to human comfort with analysis software. In this research, descriptive-analytical method was utilized. Most of the data were gathered through library studies and required climate information was extracted from the data according to the weather station (Mehrabad Airport) in Tehran city throughout 10 years- period (2009-2019). By conclusion, in this city, the fall and winter seasons and the month of April have cold conditions, therefore applying mechanical heating and high thermal mass is needed for most of the year. One third of a year has human comfort conditions. In Tehran city natural and mechanical cooling is required for three months of a year due to warm conditions.

In some climates, massive buildings made of stone, masonry, concrete, earth and … can be utilized as one of the simplest and most effective ways of reducing building heating and cooling loads. Very often such savings could be achieved in the design stage of the building and with a relatively low-cost. Such declines in building envelope heat losses combined with optimized material configuration and proper amount of thermal insulation in the building envelope could help to decrease the building's cooling and heating energy demands and building related co2 emission into environment. This paper presents a typical study of thermal mass buildings, especially, a kind of masonry building called YAKHCHAL, where most of the buildings are constructed out of mud or sun-dried bricks. They behave like a thermal mass building types. In this climate, there are great many buildings which have been adapted to their climatic conditions. Such traditional solutions may help to overcome the energy crisis which the mankind faces today and may face in the future.

Abstract The Qajar dynasty was a time of civil wars as well as the wars against Russia, meanwhile, Qajarid Shahs, understanding the power of sublime art both in internal and external political relations, tried to expand and renew the style of the mural decorations which is the issue of this article. Increasing the relations with European countries like England and France, Fath Ali Shah and his court were influenced by European diplomacy, culture and art. Also they were deeply inspired by pre-Islamic royal and artistic concepts and styles. Early Qajarid murals were the obvious return to tradition this study tries to identify the sources and socio-political reasons that lead to this movement. In the other hand, realizing the function of the mural decoration and political determination of the king and his court in early Qajarid period, which moved away from the common Zand theme and function (the Persian former dynasty) and followed the imperial art of the Achaemenid and Sasanid eras, can explain their formation of historical compositions and majesty of their artworks. By the seventeenth century, as a result of extended contacts with Europe the unfamiliar tradition of painting in oil on canvas was gaining currency among Persian artists. Although the medium was borrowed from European painting, the style remained largely indigenous. The influence of imperial Sassanian and Achaemenid themes also appeared on the carved figural reliefs. Mural decoration and art were led to serve political affairs in order to legitimise the Qajar dynasty.

Power plants with complex technology have various gradations in design process so that this level in the current time by maintaining the goals of sustainability and sustainable development have a critical importance. These buildings require to be sustainable according to their complexity to provide the finance and discrete budgets for functional needs, meanwhile to design solutions to avoid creating pollution and the reduction of energy should be careful and they are in their life cycle which have a social function. These solutions are possible to offer providing a method in design. Focusing on interventional and unique procedures in design can be very efficient. The present research is applicable with the aim to emphasize and recognize the importance of prioritizing in selecting different areas in combined cycle power plants based on the parameters of sustainable development and responds to the question on what priority should be set in the areas of combined cycle power plants,while observing the principles of sustainable development in the direction of control and decrease of economic, social and environmental risks, describes the infrastructures of sustainable development in the areas of combined cycle. Therefore while addressing senior managers, advisors and contractors ,has presented a list with the consultation of the experts and in the second stage through scrolling using questionnaire and survey from experts and AHP software analysis among consulting companies managers, contractors and professionals the criteria were prioritized in hierarchical method. The economic-functional criteria with rank 0.541 have been in the first priority of attention form the experts’ choice and considering the effect of these criteria on the choices, the choice of steam in combined cycle power plants was placed in the first priority with final weight 0.313 and the gas area was determined in the second priority with final weight 0.266. This was also true in the sensitivity test. Thus paying attention to the functional criteria in order to gain economic productivity in the steam area was defined in the priority of attention.
