المستخلص: Early childhood is a crucial stage of life in terms of a child physical, intellectual, emotional and social development. Growth of mental and physical abilities progresses at an astounding rate from birth to age six composing 50% of the intelligence of the child at this stage.. The progress of nations and communities is measured by the extent of their interest in the world of childhood and the development of the educational system in line with the developments and requirements of the times. So it is the responsibility of the community to focus on children and support their growth and development as they reflect the image representing the community in the future. The importance of the establishment of nurseries and kindergartens is represented in providing generous purposeful environment for children in the first years of age to help the continuity of growth and integration of mental, emotional, sensory and kinetic abilities.. The absence of a theoretical framework that integrates contemporary educational and architectural trends for the child's architecture reaching general strategies, constitutes the main research problem. This problem arises from the lack of a knowledge in the field of architecture in providing theoretical frameworks for designing solutions for the architecture of children (as a result of literature concentration on fragmented and separate attributes), as well as the absence of a dialectic and reasonable interrelation between architectural theories and child's educational and psychological theories.. In light of the research problem, the aim of the present research is determined at the establishment of a theoretical framework that integrates educational and contemporary architectural trends for building the general strategies and deriving the designing solutions for the the friendly - child architecture. This requires the building of the theoretical framework , and then applying the framework to selected architectural environments in order to draw the bases and mechanisms of designing of the architecture of the child. In light of this, the structure of the research includes five chapters : Chapter One is allocated to demonstrate the importance of the role of nurseries and kindergartens in the development and growth of the child and within two axes : one focuses on the architectural and educational history of nurseries and kindergartens on a global level. The second axis deals with the history of nurseries and kindergartens at the local level. The intake Chapter Two the psychology of play and intellectual approaches & their reflection on the requirements of the child's environment within the two axes. The first axis Includes growth and development of the child and the psychology of play. Either second axis deals with intellectual approaches and it's reflected on the child's environment includes the intellectual approach of Pedagogy and intellectual architectural appraoches down to build four general concepts common to reflect the desired characteristics of the child's environment - including the external environment and internal environment - represented by (learning environment by doing, simulation, workshops and laboratories / rich exciting environment, working as a third teacher for child / sustainable environment - health, economic and social / Home - Like environment of psychological and physicist safety).Chapter Three deals with extracting the main strategies in the child's environment (external and internal) and the resulting indicators reaching to the final theoretical framework. Chapter Four aims to apply the theoretical framework and the resulted strategies on selected architectural environments (nurseries and kindergartens).Chapter Five presents the final conclusions and future recommendations. The results of the research in both its theoretical and practical aspects led to clear mechanism to achieve a child - friendly environment that supports the growth and development of the child and meets his physiological, ,psychological , mental and emotional needs. This mechanism enables the designer to innovate convenient solutions to attain a friendly child architecture.

المستخلص: يرتبط تطور مفهوم الاستدامة في التصميم العماري المعاصر مع تطور وتقدم التقانة وتوظيفها في انتاج العمارة، اذا مثل التفاعل بينهما حافزا مهما للمعماريين نحو تقديم صيغ جديدة للتفاعل مع البيئة المحيطة وما تطرحه منمحددات في عملية التصميم العماري. في ضوء ذلك، ي | The development of the concept of sustainability in the Contemporary Architectural design is related to the progress of technology employed in the production ofarchitecture ,the interaction between the two concepts is an important incentive for architects to provide new forms of interaction with the surrounding environment and itsdeterminants in the Architectural design process. In View of this, The research sheds the light on two fundamental concepts which took place in the last few decades in both Architectural Theory and Design : "Digital Architecture" with it's impact on Current Design approaches, and "Sustainability" with its role in formulating approaches of sustainable design, which the an exploration of the nature of their relationship and its impact on achieving "sustainable identity" is the pivotal core of this research. With Digitisation and new technological challenges resulting from rapid acceleration in the evolution of digital design and software and what provides of potentials in design and construction, thedigital architecture synchronized with the requirement of sustainability produces active and influential concepts, important changes in the Architectural mindset towards restructuring both process design and production methods in contemporary architecture, offers new insights into the generation format digital and Architectural resulting ' strategies for sustainable design.By examining the foundations associated with the concept of sustainability and sustainable architecture in the digital age, to determine the general problem in the "absence of a clear conceptual framework of the concept of sustainable architecture in the light of the impact of digitalization age. " And identified the specific problem on "the need to provide clear conception about employing digital architecture as as a method of design for achieving sustainable architecture". Resulting in the crystallization problem associated with : "the absence of clear framework of employing digital design appraoches in identify mechanisms for achieving Sustainability in Digital Architecture.Accordingly,the research assumes that "sustainable identity Association employ digitization in sustainable Architectural design process through the activation of intellectual and formal elements of digital architecture for digital design and select stratigiath.

المستخلص: توجهت الادارات التخطيطية الحضرية لعدد كبير من دول العالم الاكثر تقدما عمرانيا واقتصاديا نحو التاكيد على ضرورة اعتماد مفاهيم الانشاء الحضري الصديق للبيئة كاساس في انتاج مدن المستقبل التي تضمن حق الانسان والطبيعة على السواء في الاستمرار والبقاء, وذل | The urban planning administrations of many of the most developed countries, both cultural and economical, have advanced towards the emphasis on the need of adopting environment friendly concepts of urban construction as a base to establish future cities which guarantee both human and nature rights in permanence and survival through simulating the function of such construction with the function of the most sustainable systems in the universe. Such simulation involves a return to the natural ecosystems which had independent functional mechanism and integrates with everything presented by the surrounding environment, in addition to understanding the basis of such mechanism this simulation involves translating this mechanism to a number of primary laws that can be recruited in the production of an environment friendly ecological urban model.The aforementioned achievement of such purpose seeks to transfer the urban performance system to an integral and complete part of the natural performance system surrounding it. Such purpose will be the research foundation of all five chapters which proceed to give a primary clear picture of what the environment friendly ecological city is. The research, in its introduction, is based on a number of readings and briefings of previous literatures related to the subject matter which reveal the existence of a non - cognitive integration concerning many aspects of this subject. Therefore, the research issue individualizes in the "lack of available knowledge concerning the foundations of designing and planning the environment friendly ecological city". Accordingly as provided by the research issue, the research aims to "establish a general informative base of design and planning foundations of the environment friendly ecological city".So this research in its continuous quest to solve this issue, has assumed that "the emergence of human urban agglomerations has completely separated from the locations of the natural environment, and its developing towards environment friendly ecological agglomerations would depend on finding a complete urban structure grounded on a numbers of foundations and standards which are basically inspired from the qualities of systems in such natural environment". The research, in proving this hypothesis, has relied on a scientific descriptive analytical methodology in which its general structure is developed progressively. This methodology, in the first part of the research, seeks to build an integrated theory base about the ability of recruiting natural ecological laws in the sustainable urban construction operations. In the second part of which, it seeks to detail the designing and planning foundations of such construction and to verify its dependence ratio in different international experiments specialized in constructing environment friendly ecological cities. In translation of this methodology, the research contained a general organizational structure which includes an introduction and five research chapters. Chapter one, under the title "the origin of ecological city emergence" came to clarify the historical roots of ecological city emergence and the most important modern environmental urban problems which prompted its adoption in the construction operations of modern cities. This chapter represents the introduction of chapter two which is under the title" what is the ecological city in its environmental surrounding". This chapter explains the concepts of ecological city, its natural planning philosophy as well as the planning tools that describe it as a lived urban machine. Thereafter, comes chapter three which demonstrates "the design and planning foundations of structure components of the ecological city". This chapter shows the basic elements to establish the structure of the environment friendly ecological city and its most important design and planning foundations. , this chapter establishes for the fourth chapter which entitled as "the ecological city in the international experiments". This chapter sheds the light on detailed analytical study of many selected case studies in purpose of verifying the ability of implementing the findings of the theoretical framework of the previous chapters in reality. Chapter four of this research attains the conclusion of a number of mutual environmental decisions adopted by the sustainable developmental urban policies in many of the most successful countries in the field of establishing environment friendly ecological cities. These four chapters prepare a number of summary conclusions and recommendations which are shown in chapter five of this research "final conclusions and recommendation" which includes a reliable ruler of measure to find integrated components for an efficient ecological urban structure.

المستخلص: الاسكان في العراق عموما والعاصمة بغداد خصوصا يشكل حاجة مهمة ومسالة كبيرة في حياة البغداديون واصبحت هذه الحاجة مشكلة معقدة تزداد تعقيدا يوما بعد يوم لعدم وجود خطط وبرامج وتوجهات اسكانية واضحة مع تفاقم المشكلة الاسكانية لمدينة بغداد مع احتمالية مضاعفة سكانه | Housing in Iraq in general and Baghdad in particular is an important need and a big issue in the life of Baghdadis became the need for a complex problem is furthercomplicated by the day for lack of plans, programs and orientations of housing and clear with the worsening problem of housing for the city of Baghdad, with the potential to double its population in the past (25) years to come, The situation worsens during the years of economic blockade, making housing moves from the stage of "disability" to the "problem" and then "crisis" as a result of the stop mass housing projects. Making the purpose of this study to develop solutions, plans and programs to solve this housing problem worsening and that turned into a crisis, and we are here to put the definitions and terminology NES definition of all citizens by the study of the housing crisis in Iraq in general and all of Iraq's provinces for the variables details of the housing crisis in which the identification of the housing stock The housing need and housing problem and overcrowding, as well as growth rates and population density. A study of some experiments specialized Arab a heart housing, similar to the housing crisis in Iraq and to identify solutions to problems and design and style of implementation and management expropriated the land and the style of the distribution of residential units and how to get the citizen limited income and employee housing units for the purpose of drawing lessons them and get to know the method of solution so housing crisis, Assuming that the planning studies, the overall city of Baghdad and to ensure that the expectations of population growth for the short term and the medium and long term, as well as housing a high - density city of Baghdad is the base discreet to solve the problem of housing the growing alignment between housing high - density expected with theconditions of the city of Baghdad, environmental, social and economic, as well as sustainability is the prerequisite to solve that problem, and then put the plan residential comprehensive City Baghdad to resolve the housing crisis in which up to the year 2040 no status plan over 25 years starting from 2015 and ending in 2040 after a study of the housing stock in Baghdad and the population growth rate and population growth, overcrowding and housing need and housing problem to be able to these data of knowledge population and housing stock and housing need and housing problem and the growth rate and population growth for the year 2040. Plan was developed that we can which calculate the number of residential units to be implemented until 2040 with COST pilot for the purpose of implementation of these units, after we got to tabbed implementation of price per square meter (units of housing and services for infrastructure) by the Ministry of Construction and Housing and the plan that has been applied by the competent authorities of a heart housing in Iraq would have identified the correct pace towards resolving this crisis and to be able to live from Baghdad's housing cream worthy of their history and their culture and welfare of confidence.
