Oil resistant o-rings on the basis of acrylonitrile butadiene rubber (NBR) reinforced by nanoclay were produced via a traditional industrial method in accordance with aviation standard, AMS 7272. The production of nanocomposites comprised the compounding of nanocomposite with optimum mechanical properties and minimum contents of used carbon black and nanoclay, design and manufacturing of the required mold and finally compression molding of the oring. Mechanical and morphological properties of NBR/nanoclay compounds were optimized by introduction of proper contents of a compatibilizer containing a mixture of resorcinol and hexamethylene tetramine through using a master batch production method. The prepared nanocomposites were characterized using X-ray diffraction (XRD) analysis, curing measurements and tensile test analysis. The XRD analysis showed that the compatibilizer facilitates the intercalation of nanoclay silicate layers with the rubber chains which leads to the increase of their basal spacing. The cure characteristics of the nanocomposites showed a decrease of scorch time and increase the cure rate index with the nanoclay loadings. Furthermore, the minimum scorch time and maximum cure rate index could be achieved through using the appropriate content of compatibilizer. The results exhibit that the nanocomposites containing the compatibilizer have higher mechanical properties especially at higher deformations compared to the corresponding uncompatibilized nanocomposites

Macro and micromorphological investigations were conducted on selected Xerepts soils from southern Iran to identify changes in soil characteristics with time. Soil samples from similar pedons of four irrigated orchards ranging in age from 20 to 100 years were studied and compared with soil samples of a pedon of non-irrigated land. In addition to routine analyses, undisturbed blocks of soils from each horizon of pedons were prepared and used for micromorphological studies. Field data, micromorphological obsrevations and laboratory data, permitted an overview of changes in soil characteristics and their role in the pedogenesis. Changes observed include the type and distribution pattern of voids, translocation and accumulatin of CaCO3, and the soil fabrics. Calcitic hypocoatings, and compound dense complete calcite infillings in vughs, and large voids were attributed to precipitation as induced by irrigation. There seems to be an increase in organic matter content with time. This needs to be further studid to establish condition for carbon sequestration and increased soil quality in arid regions.

The aim of this study is to compare the ideas of Arabic rhetoricians and linguists about the direct and indirect meanings of interrogatives. For this purpose, the ideas of linguists about the notion of speech acts in the field of pragmatics were investigated and also the viewpoints of rhetoricians in the field of meaning (Ma’âni) were studied. After gathering the ideas of the two groups, a comparison is made to show the similarities and differences of such ideas. The results showed a number of similarities like the division of utterances to constatives and performatives, paying attention to indirect meanings of performatives and some of similar indirect meanings. All of these are reasons of the influence of ancient rhetoricians upon modern linguists. However, undoubtedly, there are a number of differences between the two; such as their different scope and some of different indirect meanings, which imply the innovations of linguists and their attention to other dimensions of performatives.

Background: Today the facade of newly constructed buildings is an important issue in the urban context, particularly the historic context, which determines the presence of building within the urban landscape of a district as the last step of construction operations of each building. Existing criteria and instructions for facade design of new buildings in urban-historic districts have been developed based on a variety of components, e.g. historic patterns and vernacular materials, as a guideline and framework for owners and designers; so that the facades can be appropriate and consistent with the historic context and buildings of the district and also in harmony with each other. Despite the attempts to meet the targets, a broad variety of newly constructed facades can be observed now throughout the historic areas of the city, which may range widely in terms of harmony with each other and consistency with the context.
Aims: Given the issue explained above, this article aims to detect the weaknesses and drawbacks resulted from the failure to meet the objectives of the instructions on façade design of new buildings in the historic area of Tabriz; hence the existing guidelines on façade design in the historic area of Tabriz are analyzed to investigate the dimensions of their feasibility for newly constructed residential buildings. The objective is met through multidimensional attention to the facades of new buildings.
Methods: In this article, the implementation process is thus qualitative and the data is collected through a descriptive-analytical method based on scientific references and field research.
Findings: The investigations on newly constructed residential buildings in the historic area of Tabriz reflect two major types of failure (i.e. theoretical and practical) in regard to the feasibility of façade design instructions.
Conclusion: Therefore, corrective measures and revisions are required theoretically in addition to the actions necessary for implementation of façade design instructions.

One of the most beautiful aspects of Iranian oral literature is traditional melodies and songs that speakers of different regions and ethnic groups intone at work or at ceremonies or special occasions. These songs, from the very old eras till now, have been applied by human in aggregations and  ceremonies. Some of these songs have arised from Iranian ancient culture, and have retained  heir old roots. Sarkavir region, located in the southern border of Semnan province and adjacent to the northern edge of the central desert, has some neglected songs. Dialect of this region, with more similarities to the ancient Khorāsān dialects, has remained largely intact for various reasons, including the inaccessibility to the city. These poems, related with mourning and rejoicing customs, and songs by women in ceremonies. have maintained their strength and power in funerals and wedding ceremonies until now.  In this article, we have tried to introduce "Soru" and "Ongâre" as two special wedding and funeral songs, analyze their literary and anthropological aspects, and through it, explain some features of their speakers.

One of the most beautiful aspects of Iranian oral literature is traditional melodies and songs that speakers of different regions and ethnic groups intone at work or in ceremonies or special occasions. These songs up to mow now have been applied by human in manifestations and ceremonies. Some of these songs have risen from Iranian ancient culture and have retained their old origins. Despite the attractiveness of words and meaning, some of the melodies for various reasons, including the inaccessibility to the city has remained largely intact. These poems are related to rejoicing customs. Poems, based on ancient traditions, have maintained their strength and power in wedding ceremonies till now. Ollāh is one of these fantastic songs which residents of southern villages of Shahrud and Damghan (Torud and Sarkavir area) from the far past use in their wedding. This ancient tradition has retained its effervescence and reliability yet. In this article we have tried to firstly introduce Ollāh and review the features and specifications of its literary aspects. Furthermore, we have analyzed some features of the popular culture of its speakers.

Work Songs during the work have a great extent .Several examples of these songs can be observed among the farmers, stockbreeders and weavers. These songs make the work space free from the monotony and strictness alleviating the tiredness and exhausting pain of work, and reinforce the men and women effort, resulting in  movement sensation and hope during the work. The composed poems in the field of work and business in Kohgiluyeh and Boyer-Ahmad, form at large scale the literature of this area. In the environment of work, men and women from Kohgiluyeh and Boyer-Ahmad have had the poem in tune with someone who was doing the work. This kind of poem has had an appropriate music and sensation. They are anonym composers who compose these songs to show their happiness, sorrows, loneliness, and pains. These songs have had an important role in transferring the cultures; rituals and manners between the generations. In the rural and tribal society of this area, there have been some works such as farming, rice milling, milking and dyeing where the workers composed songs to have the pleasure and fun. This article tries to consider and analyze the agricultural songs (rice milling, rice farming), livestock songs, breeding and knitting songs.

Relying on the psychological theories of Ibn Sina and Mulla Sadra, this argument examines the movement of the human soul in two stages: “when the soul is connected to the natural body” and “after its separation from the natural body”. By demonstrating the possibility of movement in the immaterial soul, it is also possible to prove and explain the movement of other non-material beings. When the soul is connected to the natural body, the unified human soul can move and change independently of the power and matter within the body. This independence suggests that other non-material beings can also undergo movement without reliance on matter. However, after the soul is separated from the material body, Ibn Sina considers the possibility of the soul’s evolutionary movement but lacks sufficient grounds to prove it. In contrast, Mulla Sadra explicitly denies the evolution of the soul in the intermediate state but provides psychological foundations that support the possibility of the soul's evolution. These same principles can also demonstrate and explain the movement of other immaterial beings.

Taking advantage of geometry has been always a current base in Iranian traditional architecture for accommodate survey among form, stability and coordination. Recognition of components’ geometrical behavior along organic :union: making’s direction among skeleton, space and background systems causes integrated feedback formation among effective elements in collection’s stability. Based on existing geometrical limitations in their structures and coordination, Iranian girih as modular units are capable of developing in x and y axes by considering visual values and actionable efficiency. According to controlled process of Iranian girih s’ structure in mentioned axes, transferring this discipline in z axis for -3dimensional action’s maintenance of structure collection is also discussed. So, firstly current article has considered usage method of girih geometry productive parameters by Grasshopper graphical coding software, and then resulting collection of various forms from girih geometry is introduced as a population of analyzable genes by genetic algorithm method. Thereby, supports’ optimized location is developed by -3dimentional action among components for reaching an efficient form of girih’s geometry. Adapted to survey, prevalent population of introduced genes collections is selected after simultaneously analysis of form and mechanism by Karamba addition and the most optimized status of supports’ location is selected in circumstances that structure’s components has the minimum stress. Then, the optimized state and organized sample in supports’ location are considered to explore about resulting behavior in both states toward load transferring to case foundation. According to this study results, it can be concluded that by defining certain legislations, geographical mechanism of Iranian girih causes an integrated behavior’s controlling and multi-dimensional action among quality parameters such as cladding structures’ designing and quantity parameters such as proper behavior toward forces.

This study tries to examine the syntactic characteristics of imperative structures with figurative meaning in the Russian language and the manner of their translation and description in Persian. Grammatical forms in the Russian language, apart from their original meaning, can also be applied in auxiliary and figurative meanings. The imperative mood in this language is not exempted from this rule. The original meaning of imperative mood predicates to an action that has been requested i.e. when a person commands someone to do an action. The imperative mood in the Russian language, with giving away its original meaning,  is applied for expressing various grammatical meanings such as action conditions, necessity, possibility to perform an action, unexpected action and so on.  This research is aimed at finding an answer to this question, that whether such structures with figurative meanings have special syntactic characteristics, compared to the structures with direct meaning, and is there any relationship between direct and figurative meanings in these structures? In this article, we will analyze 11 most important figurative meanings of imperative constructions in the Russian language, embedded in more than 60 examples, and will study the most common methods of their translation into the Persian language. Analyzing the syntactic and grammatical characteristics of imperative constructions with figurative meaning in the Russian language and various methods of their translation into Persian, due to fundamental syntactic and structural differences of basic and target languages are the most important aims of this study.

Neighborhoods and public buildings are required to comply with specific criteria from the perspective of passive defense to survive and to continue its activities in conditions of crisis. In order to achieve the criteria, the recognition of threats and the priority of local public buildings based on various items can be helpful. The priorities explain which the user is more sensitive, more vulnerable and in times of crisis can be useful. The aim of the research is the priorities of existing buildings in the neighborhood on the field of functional necessity, the application in crisis and the sensitivity of the enemy. In times of crisis, Cities and accommodation and activity centers as well as public buildings as centers of human and material capital are the target for the enemy and attack them causes great damage. Accordingly, the neighborhoods that form the cities and public buildings in there are always on top of the important purposes of attackers. So through this paper study the urban buildings in the neighborhood of three terms of the amount of applicability in crisis, the sensitivity of the enemy and the sphere of functional necessity. Delphi technique used in this study and the research population included all defense experts and architecture, of which 12 samples selected. In general, the concept and household of neighborhood can be defined as different aspects of social, psychological, mental, cognitive, architecture (physical) and politically. Regarding to the world literature, two words, township and neighborhood can translated as the concept of neighborhood. While included the populations of them, respectively, 2000 and 10000 and 15000 to 40000 people. The first word is residential neighborhood that has a distinct identity but the second word refers to an area that in addition to large size has a diverse career opportunities. In urban classification, neighborhood is the first category and then the region, district, city and beyond, the next field. This neighborhood has the necessary equipment, including schools, supermarkets and entertainment centers. Public buildings of neighborhood that used as the first area of urban buildings including banks, shopping centers, libraries, mosques and religious sites, indoor clubs, schools, small industrial sites, hospitals, clinics and laboratories, emergency centers, subway, bus terminals, car parks, restaurants, fire station, power station, gas station, water and security centers. The purpose of measuring the important urban centers whit this benchmark is to find places that have the most users at the time of the invasion of the city, also have more effects in comparison with other users. This priority known against those places that is not effective in crisis. Identification of such sites has the advantage of looking for lasting strategic locations and finding solutions to maintain the physic and performance of those sites. Also, identify the places that the enemy does not considered as important targets and remove them from the priority of places in order to secure. If the domain of passive defense extended by the presence of some vital services after enemy attack, then the activities and places that are essential will identify during the threats. Other places that are diagnosed unnecessary or less effective, have the potential to change the physic to new performance. Provided that the architectural design is flexible and meet the vital needs of the city. In this study, the Delphi technique performed for the Prioritization of public buildings in terms of passive defense in times of crisis. The first point in the Delphi panel is the way to choose its members so that usually invited 10 to 15 specialists is the best for participation in Delphi. Delphi panel members for this study selected for non-probable sampling and combination of purposive or judgmental and sequential methods of 12 patients. In this method, the panel members usually offer their opinions in numbers, then the average is calculated by agree and disagree panel members, subsequently this information notified to members to obtain new ideas. In the next step, each member offers new opinion or modifies his previous opinion based on information obtained from the previous stage. This process continues until an average number is stable enough. The questionnaire designed as for the proposed priorities. According to the results shown the average per any local user, calculate by priority on the amount of applicability of the crisis, the sensitivity of the enemy and the sphere of functional necessity. In this way, there is priority on the amount of applicability of the crisis, the sensitivity of the enemy and the sphere of functional necessity for every 10 local buildings. The result in neighborhood suggests that priority applications on the sensitivity of the enemy, the first priority attack in the enemy point of view according to the panel members are military statins, power stations, gas stations and water centers. Mosques and religious sites, clinics and health centers, subway, parking and fire stations are as second priority and the banks, shopping centers and nonprofit services, libraries, indoor clubs, schools, kindergarten and restaurants is considered worthless attack. The priority on the sphere of functional necessity, clinics and health centers, subway, fire stations, power stations, gas stations, water centers and military stations are necessary, parking is rather essential and restaurants, libraries, Mosques and religious sites, indoor clubs, schools and kindergarten are non-performance. Also in priority on necessity in crisis, banks are non-usable, parking, schools and kindergarten, indoor clubs, Mosques and religious sites and libraries have possibility of granting new performance (indirect use) and shopping centers and nonprofit services, clinics and health centers, subway, fire stations, power stations, gas stations, water centers and military stations are a direct function (Maintain existing performance). The results in the prioritization in public buildings in the neighborhood suggest that the use in the prioritization in public buildings the neighborhood includes 10 users and each user also contains one or two sub-user. The applications analyzed based on three priorities (the amount of applicability in crisis, the sensitivity of the enemy and the sphere of functional necessity). The priority applications on the sensitivity of the enemy, the first priority attack in the enemy point of view according to the panel members are military statins, power stations, gas stations and water centers. The priority on the sphere of functional necessity, clinics and health centers, subway, fire stations, power stations, gas stations, water centers and military stations are necessary. In priority on necessity in crisis, shopping centers and nonprofit services, clinics and health centers, subway, fire stations, power stations, gas stations, water centers and military stations are a direct function (Maintain existing performance). Designing complex subway station and mixing them with crisis management provides an opportunity to understand multi-functional of station spaces. This article seeks to reduce vulnerabilities in the analysis subway stations measures to be considered as temporary accommodation in an emergencies and provide a safe space research questions inclusive weather do you have ability to the performance is also, in addition to its roles as station for transport and cultural and commercial complex; in critical condition become to temporary housing? Or what factors effect on flexibility of architectural complex subway? We have very good station complex in our country. A station complex itself consists of several levels of services areas include entertainment and office. This type of sorting and spatial layout is designed based on the needs. But in this paper we discussed bout benefits of this wide space and advantages of all the facilities and equipment in emergencies. Developing countries, including Iran, in addition to being more prone to accidents and natural disasters than other communities, total human casualties and property damage in case of accident these communities are heavier. To prevent the occurrence, planning to rescue damaged area and temporary accommodation, all communities need new Disaster Management. In the present study we have tried through a multi-functional and flexible design, the central station with the highest integrity economic, social and environmental be prepared to deal with the sudden crises. Despite the unexpected event and the space subway stations is located in the basement created a good spaces for sheltering people affected.

Introduction and Literature Review: Reducing energy consumption and greenhouse gas emissions to alleviate the effects of global warming have become a worldwide necessity. This matter has significant importance in Iran, because Iran has the seventh ranking position of global greenhouse gas emissions and its rate of growth is above global average. Building construction sector is experiencing a fast-paced growth in developing countries, like Iran, due to growth of economy and rapid urbanization. A large number of buildings are being built for residential, commercial and office purposes every year. Built environments are responsible for about 40 percent of energy consumption in Iran and it is generally approved that the greatest portion of built environment is dedicated to residential use. Energy consumed in producing and processing building materials and in the processes of building a house, is usually calculated using embodied energy concept. Until recently, it was generally accepted that the energy used during the occupation of a building represented a much higher proportion than its embodied energy; thus, great efforts were put into reducing energy use in this phase. New and improved technologies have reduced the operational energy through a variety of solutions, including energy-efficient equipment and appliances, improved insulation levels, low energy lighting, heat recovery systems, the provision of solar hot water systems, photovoltaic panels for generation of electricity, and other renewable technologies. However, these measures often imply an increase in materials use and energy demand for their production, which explains the growing importance of other phases in the total life cycle. According to the global literature, embodied energy of a building accounts for one third to one fifth of the total life cycle energy consumption of a specific building. However as the global trend for the new developments moves toward the zero energy/carbon buildings, the importance of the embodied energy increases. In fact embodied energy is one of the leading parameters in assessing building’s environmental performance, because in building projects, vast amounts of building materials are needed which consume great amounts of embodied energy and thus have negative effect on environment. With this preamble, improving energy efficiency of the existing dwelling stock of urban regions will increasingly be part of achieving sustainable development in future. Although this aspect of achieving sustainable development has been the subject of many global practices in recent years and global literature is almost rich in the calculations and analysis of embodied energy and life cycle energy consumption, this matter has been neglected almost completely in Iran and those few studies conducted focusing on energy in urban planning and designing fields, are mainly concentrating on transportation sector. Thus the main goal of this study is analyzing the sustainability of urban residential sector with focusing on embodied energy consumption. Methodology: In this regard, residential sector in Shiraz Metropolitan has been divided into seven different dwelling types including central-yard houses, attached terrace houses (one story houses, two story and three story houses), apartments (which are buildings of four story and above), villas and declined houses. Gathering raw data in this study was challenging, considering the fact that house building in Iran is far from industrialized and prefabricated building is really limited. Unfortunately there is no data available on the average material consumption of different dwelling types in Iran and the only study similar to this was done focusing on building structures. Using this only available data, we built our data bank in Microsoft Office excel and then focused on computing average embodied energy via multiplying embodied energy of common building materials extracted from a report conducted in the University of Bath titled “Embodied Carbon: The Inventory of Carbon and Energy (ICE)” into average material consumption based on building structures. Another point we had to take into account was the unit of the available data; while embodied energy of materials were presented in gigajoules per square meter, average material consumptions of dwellings were presented in different units from square meters, to cubic meters, kilograms and blocks. So using density of materials we established a second data base with similar units. Normalizing this raw data through dividing average embodied energy of residential dwelling by dwelling area we calculated the capitation of embodied energy for each dwelling. Afterwards we prioritized embodied energyconsumption of dwelling types from lowest embodied energy capitation to the highest as follows: brick and wood structures with about 3 GJ/m^2 embodied energy, clay brick concrete structures, clay brick steel structures, brick concrete structures, brick and iron structures, and at last brick steel structures with about5.35 GJ/m^2 embodied energy Results: To be sure of the validity of these comparisons analysis of variances (ANOVA) and Post Hoc Tests (Least significant difference- LSD) have been applied to these data in IBM SPSS statistics 19, and the result has been positive. Then collected data were shifted from structure types to dwelling types and we found out that central-yard houses with 3.6 GJ/m^2 embodied energy per capita are the most energy efficient dwelling types. After this type in sequence lay one-story terrace houses (4.21GJ/m^2 ), apartments (4.26GJ/ m^2 ), two story terrace houses (4.67GJ/m^2 ), declined houses (4.81GJ/m^2 ), villas (4.84GJ/m^2 ), and three story terrace houses (5.21GJ/m^2 ). Discussion and Conclusion: This paper highlights the need to use location-specific data in the development of building assessment schemes and the issues related to the use of embodied energy assessment for the building sector. Absence of localized data base on building material consumption on the basis of dwelling type and lack of data on cradle to grave embodied carbon and energy of common building materials were the most important obstacles in this research. On the basis of international research, paint, bitumen, platevirgin, sheet Galvanized-virgin, steel, ceramics, primary glass, iron bars, lime, cement, and common brick are the most energy intensive materials. So on account of lack of localized data, we used international embodied energy of common building materials (cradle-to-gate) to calculate embodied energy of different dwelling types. Despite of major shortcomings in data base, noteworthy conclusions have been deducted from this work which are summarized as follows: traditional form of housing in Shiraz which is known as central yard houses in this paper with brick and wood structures (in which there is a yard in the center of the block and the residential parts are located at its periphery) are the most sustainable form of housing according to this research criteria and case study. This may owe its accomplishment to the low embodied energy of common materials used in this type of housing which we may call the most environmental friendly form of housing in Shiraz. Furthermore there is a substantial lack of data on embodied energy and carbon of materials in general, and in particular on the embodied energy and carbon of buildings to be able to do an entire evaluation of buildings in their life long period. So to do a complete research in building sector (life cycle assessment), including embodied energy, gray energy, operational energy, induced energy, Demolition/Recycling Energy, and retrofit energy are unavoidable.

Energy efficiency and comfort consideration in building, contribute to significant energy saving and improvement of spatial quality. According to the importance of energy issues and lack of researches on energy use in educational buildings, climatic variation in the country and huge amount of energy consumption in educational buildings, the need of redefinition environmental design criteria is essential.
The main purpose of this article is to assess the influence of different design variables on comfort condition and energy consumption in the hot-Arid climate of Tehran. Most of the literature concerned with energy performance of school buildings is focused on using saving methods such as utilization of solar energy, constructional issues such as thermal insulation, infiltration, thermal mass, building materials, sun shadings and HVAC performance while assuring thermal comfort and indoor air quality of the building. However, the topic of energy performance and comfort condition of schools located in Iran’s climatic conditions has not been explored.
Nowadays, the subject of energy and optimizing energy consumption in different buildings and different societies is of great importance. On the other hand, energy experts claim that in designing educational buildings, natural energy resources should be used most. This subject is related to the energy consumption of schools. Furthermore, the positive effect of thermal and visual comfort on the quality of students’ education has been confirmed. Educational buildings generally are spaces with different functions.
However, classrooms not only have a central role, but also cover a great part of the school surface. Classrooms are the most fundamental and important units of the educational buildings in terms of energy consumption and thermal comfort. Students spend most of their time in the classrooms. Classrooms are more important, given the relative congestion in comparison with other educational spaces. Due to this fact, proper ventilation is considered necessary. Furthermore, students’ presence as latent thermal energy sources needs special attention in hot seasons. On the other hand, the same thermal sources can play an effective role in creating the comfortable conditions. Therefore, according to the difference of using pattern of these places and their higher internal heat gain, energy saving patterns in designing office and residential buildings cannot meet the needs of designing these buildings.
Methodology
This research using simulation method is looking forward to realize the influence of different physical variables on energy consumption in educational buildings in Tehran’s climate; the different circumstances that were resumed by diverse variables were assayed. this process took place with the help of E quest energy simulating software and during this process in two separate parts, the independent effect of each variable and the simultaneous influence of applying diverse variables on energy consumption were simulated and its results were compared and discussed in various steps.to enumerate the most essential effective parameters in determining the amount of energy consumption in educational building in Tehran’s climate, we can point out the infiltration rate, heat isolating of the building roof and windows dimension.
To understand the range of influence of each variable on the comfort condition and energy consumption in the classroom, the difference between the maximum and minimum energy consumption obtained for each of the evaluated variables was considered. This difference represents the potential savings that can be achieved by improving a variable within the considered range of values. In this work, the four main orientations were analyzed.to observer the influence of design parameters on energy consumption, a base case classroom was designed and then the absolute and simultaneous effects of different parameters were assessed. The base-case was a common classroom to where all changes were applied and examined. Based on the similar studies, the recommended value for each design variable was determined to achieve a high
performance classroom. The fixed parameters of the classroom were its size and height. The thermostat of the heating system was set at 21.1 C while the thermostat of the cooling system was set at 24 C, due to the dissimilarity in the children’s clothing in different seasons. The ventilation system provides a minimum of 4.5 air changes-per-hour (ach) when the classroom is occupied. When there were no children in theclassroom, the ventilation rate will reduce to save energy and the lighting level on the children’s tables was set at a minimum of 300 lux.
Results
The results indicate that by reducing the infiltration rate of the classroom from 4.5 ACH to 0.75 ACH, an energy saving of about 65 KWH/m2.y will achieved. The airtightness of a classroom depends on windows and doors type, quality, and materials as well as on the quality of the construction process. For obtaining infiltration rate of about 0.75 ACH, designers and contractors should give more attention to the quality control of materials and construction and energy performance of the windows and the doors. Meanwhile according to the high amount of sun radiation during the year, roof heat insulation with a 6cm polyurethane layer would reduce the energy consumption by 40 KWH / m2.y in comparison with a roof without any heat insulation. Since the windows have a significant influence on the energy consumption and performance of the classroom, In order to reduce the energy consumption, dimensions and position of the windows should be choose very carefully. It was observed that the recommended size of north and south facing windows is equal to %12 of the classrooms floor area, whilst east and west facing windows should not be exceeds from %10 of the classroom area. If the windows size exceed from %12 of floor area, the glare effect would make visual discomfort for the students. In the simulation process, three types of light control features were evaluated. The results show that with the aid of smart lighting control system, the required electrical energy for lighting would reduce 34 KWH / m2.y. And finally the types of glazing have an important role in energy consumption of the classroom. It is observed that high performance was achieved when using lowemissivity
glazing to reduce cooling loads and encourage daylight in classroom. Double glazed windows shows acceptable performance as well, in all directions compared to other alternatives.
Discussion and Conclusion
After analyzing the absolute effect of each parameters on energy consumption and comfort condition in the classroom, the cumulative effect of all parameters were analyzed. It is obvious that by changing of each parameter, the effect of other parameters will be changed. In this case two combination of design variables are assessed in “set-a” and “set-b” in which the annual energy consumption of the classroom is maximum in “set- a” and minimum in “set-b”. Based on the results obtained by simulation, this can be claimed that the proper design of classrooms in hot and arid climate, like the city of Tehran can reduce the amount of energy required for cooling, heating, ventilating and lighting systems from 232 KWH/ m2.y in “set-a” to 104 KWH/ m2.y in “set- b”. It means a %55 reduction in the classroom’s energy consumption. This statics are in conformity with the results achieved by researches in European’s green school which can reduce %55 up to %75 of heating energy consumption and 30 % up to 40 % of electrical energy consumption by using different tricks.
