Abstract: شكلت تغيرات نمط المسكن الحضري في العراق خلال القرن السابق اساسا لاشكالية في قدرة واجهته على توفيرالخصوصية البيئية والاجتماعية والتعبير عن هوية البيئة المحلية.وبنقد التوجهات الاساسية لحل هذه الاشكالية والمحددة بتحليل التكيفات الواقعية للنتاج السكني او درا | The basic changes of urban residence pattern in Iraq during the previous century have formed a foundation for a basic problems in its elevation ability to provide the social and environmental privacy and expressing the distinguished identity of the local environment. Through the criticism of the trends which try to solve this problem and which can be determined in analysis the real adaptations of the residence unit and by extracting data from the real residential production, or the specialized research studies which may prepare the necessary indexes to develop, a reference is made to the weakness of what has been presented by both directions in this aspect due to the change of the balance of the properties of the resident needs in the elevation increasing towards some apparent items of self needs in a way that explain the weakness of the ability of real production affected by these trends to create the suitable adaptability to realize other needs despite of its importance. the study also points out the weakness of these studies which tried to solve these problems by independently focusing its various items from the input of its extracted induces in the residential reality whether because of the disagreement of these items or the contrast of its indices with the priorities of real residential needs or the indices of its realization.On these bases, the study suggested a compromizing mechanism that depends on presenting the indeces that can realize the balance between realizing different needs of residence and the priorities of resident wills in the elevation based on an approach that depends on the use of the potentials of both real and research aspects in presenting its special indices and to examine the ones presented in the second aspect.The suggested mechanism, therefore presented its approach within a group of procedural steps depending first on extracting the indices of the residential reality. Being a representation of the resident wills and his priorities , these indices are compared with those extracted from the realization of different needs of residence.The results of the comparison can express the ability of research aspect on presenting its indices applicable in the residential reality whereas the deference may point out the extent to which the vision varies towards the priorities of residential need of the mechanisms of their realization between the two aspects and the ability of the residential reality to create its own indices by its own realistic mechanism and priorities. It also express the styles that can be adopted to inhance the efficiency of the research aspects in this respect. To practically test the suggested mechanism, it has been applied in the urban residential production in Mosul according to the prepared approach where the extracted practical conclusions showed the efficiency of the mechanism in extracting the realistic indices to realize the different needs in the residential reality and the effecting changes. The study also showed the limits of contribution and the evaluation of the architectural role whether in practical design or in research supporting studies in supplying this production with the additional indices to develop the residential production and the factors of success and failure in their role. The research concludes with some recommendations which focused on activating the cooperation between the two mentioned aspects and the role of architectural design in practice as an active joint capable of inhencing the transfer of indices between the two parties.

Abstract: Since the building envelope represents the main axis for all thermal controlling processes being the insulation of internal environment from the external one, and as a responsive and adaptable with the external changes through its thermal conduct by preventing external effects.In addition, it includes all the external means that ensure comfort for occupants represented by walls, roofs, grounds, and all vents (doors and windows) whereas the external walls represent one of the most important structural elements that have a direct effect on the thermal performance of the building.In order to achieve the aim of the research the experimental approach and style of analytical study were adopted. The current study included two main aspects : first, the theoretical side : Which included the time delay factor calculation and cooling load depending on the Radiant Time Series (RTS) theory that achieve accurate and detailed results and ease of application The theoretical results for each hour were calculated using a new version of Mat lab program. While the second aspect included the practical test and measurement where three test chambers have been constructed as samples for the purpose of study located in the department of the mechanism and productivity of Al - Fao Engineering in Altajiat in Baghdad. The three chambers were constructed with dimensions (3000mm x 2250mm) and (2250mm) height without windows and the ceilings and walls were made the only effective resource in changing the level of thermal comfort inside it. The longest side of the three test chambers was directed towards the east - west. The walls of the first chambers have been made of perforated brick , the second chamber of thermo - stone, the third of double glazing units. The ceilings of rooms were treated by materials of humidity contraindications with thermal insulators are quite similar in order that the comparison would be only confined to the walls, and to identify the effect of the air cavity (100mm,25mm) when using it with the different materials of cladding such as ( white marble, black marble, stone of Ba Athra, composite - panel).Two iron structures were made in order to exchange the termination materials and the thickness of the cavity as well as each chamber has been equipped with (one ton) air conditioning with a same cooling degree for each chamber, the devices were connected by a scale to measure the amount of energy spent in each chamber with a fixed temperature inside, in addition to thermal sensors fixed on the inner and outer surface of the wall and in the inner space, consequently the energy exchange was considered as an evidence and indicator to the differentiation among the materials used and types of cavities in double walls. The theoretical and practical results made a good rapprochement, whereas the first test chamber (in which Brick is the material construction of the walls) has made a contrast ratio between the theoretical calculations and practical application for the electric power about 23.6%, while the second test chamber (in which thermo - stone is the material construction of the walls) has made a contrast ratio for the electric power about 22.3%. Consequently, Results of the study showed that the Exterior cladding material by using perforated brick of 120 mm thickness recorded the highest proportion of the economy in the amount of electric energy which considered to be the best thermally. However, Exterior cladding material (such as black Marble) and cladding materials with fewer block (such as composite - panel) represent the worst thermal performance because they made the lowest economic proportion of the amount of electric power. Besides, the thermo - stone material as a material of walls constructing has made an economic ratio of electric energy higher than the one made by the 240mm thickness perforated brick. The research, As well as, concluded that increasing the thickness of cavities from 25mm to 100mm may reduce the consumed amount of electric power about 6.6% when the construction material for the walls is 240 mm thickness perforated brick and 4.3% when the construction material for walls is thermo - stone.

That shows the importance of comprehensive perspective on how to build sustainable local transportation stations and determining their planning, designing and structural requirements, accordingly many studies that included either mainly or implicitly sustainability perspective were submitted, presenting the most important world experiments that had effected positively the life quality in societies in which served, nevertheless those studies and previous experiments seemed selective and collective which refer to lack of comprehensive solutions specially in planning, designing and structural aspects, furthermore the local experiments limited on developing the transportation station in to modern ones which take sustainability aspects in consideration without adopting and applying thoseaspects in active & clear way.Based on that the thesis’ topic has been identified as” Lack of previous knowledge in forming comprehensive theoretical perspective that explains patterns of planning,design and details for sustainable passengers' land - transportation station in general, and sustainability reflection in applying them locally in particular”. To justifying the thesisresult in “Providing clear comprehensive theoretical framework to the planning, designing & structural aspects of the sustainable passengers’ transportation stations, and possibilityof applying sustainable aspects in local stations” The thesis based on analytical descriptive approach, that included forming comprehensive theoretical frame for sustainable passengers’ land - transportation stations special requirements in which represented by the following terms : ( planning requirements, designing requirements, structural components requirements) which they’ve been used in applying the practical study.Samples were selected for practical study, and the previous terms applying on six samples of local passengers’ land - transportations stations, by reaching analyzing the results and conclusions, where set of conclusions obtained represented by two axis, the first axis dealt with general theoretical frame conclusions, the second axis dealt withpractical study results, the thesis presented set of recommendations and future research perspectives along with thesis potential beneficiaries Keywords/ land - transportation, sustainable transportation system, sustainable passengers’ land - transportations stati.
