The construction sector consumes large amounts of energy during the lifetime of a building. This consumption starts with manufacturing and transferring building materials to the sites and demolishing this building after a long time of occupying it. The topic of energy conservation and finding the solution inside the building spaces become an important and urgent necessity. It is known that the roof is exposed to a high amount of thermal loads compared to other elements in a building envelope, so this needs some solutions and treatments to control the flow of the heat through them. These solutions and treatments may be achieved by using nanomaterials. Recently, nanomaterials have high properties, so that this made them good elements to the strategy of energy conservation in the architectural field. Accordingly, the research problem lay in "the lack of studies that deal with strategies to use nanomaterials in the roof of the building (especially the administrative building) in order to achieve energy conservation within its spaces". Then the research aims to: "Determine the efficient of nanomaterials in the roof to improving the thermal performance and achieving energy conservation in the indoor environment of the buildings in Iraq". This research's theoretical aspect has focused on using nanomaterial and their applications in roof systems. While in the experimental aspect, an administrative application to test a mass of identical administrates building in the design. In this research, simulation of the standard roof with nanomaterial, cool roof, and standard roof systems has been done using the Ecotect program. The results obtained in this research showed that the nanomaterial affected the thermal performance and achieved the indoor environment's quality by reducing to energy-consuming in the administrative building in the hot-dry climate of Iraq.

The Effect of sustainable roofs to Conservation Energy for University Administrative Buildings: Iraq as a case study The Supervisor Asst. Prof. Ghada Mohammed Ismail Abdel Razzaq Kamoona [email protected] The Researcher Duaa Faal Nama [email protected] Abstract Sustainable roofs are an important element in environmentally sustainable architecture, as they are an effective and practical way to increase the efficiency of thermal performance in building spaces and thus achieve energy conservation in them, and what this concept contribute to reduce the consumption of electrical energy which is depends mainly on fossil fuels especially in Iraq. In fact that the administrative buildings, consume large amounts of energy because of the functional nature, higher occupancy throughout the day period, especially in Iraq with the hot dry climate, which is characterized by long summer, frequent solar radiation, high temperatures, and a large amount of the thermal loads on the envelop of building, specially the roof which is a bears a large amount of it and it has become necessary to use a sustainable roofs on administrative buildings, specially university administrative buildings, to achieve energy conservation for indoor environment of buildings, as well as improve air quality ,and increase thermal comfort ranges in them The general problem is to look for: the lack of a holistic perception of knowledge about the patterns and the role of the sustainable roof in energy conservation according to the climate of the region and the pattern of buildings. While the special problem: there is a lack of knowledge about the utilize the efficient sustainable roofs in the field of energy conservation for university administrative buildings in Iraq. Then, the general aim of the research is: To clarify the most comprehensive strategies related to utilize the sustainable roofs for energy conservation in hot dry regions such as Iraq. As for the secondary aims of the research, they are defined as: • Clarifying the types of sustainable roofs and the importance of each type to increasing the efficiency of thermal performance, and then achieving the concept of energy conservation for indoor spacing of university administrative buildings . • Finding practical strategies to explore the most efficient sustainable roofs in the field of energy conservation for each type of them, while clarifying the possibility of its application in contemporary Iraqi university administrative buildings. • Providing a hypothetical application to test a university administrative building block that is identical in design, with different sustainable roofs and in line with Baghdad's hot dry climate in order to enrich the architectural experience in general, and the university administrative buildings in particular. The research lays the following basic hypothesis: “Sustainable roofs are considered one of the efficient design solutions and one of the most effective ways to achieve energy conservation within administrative buildings in general, and Iraqi university administrative buildings in particular.” The general hypothesis of the research included a set of secondary hypotheses, which included the following: • the roofs effect on overall of thermal performance, and as a result, on achieving energy conservation for university administrative building. • Contributed all of types of the Sustainable roofs and the results of their applications a fundamental role in achieving the concept of energy conservation in the university administrative buildings. • using the environmental simulation programs to recognize the most efficient sustainable roofs which it's achieving conservation energy in university administrative buildings. The research is based in its methodology for the purpose of achieving its goals, on a theoretical study supported by a practical application of a university administrative building in the hot and dry city of Baghdad. Many sources related to the main concepts of the research were reviewed and discussed in three chapters, namely: The first chapter dealing with the concept and strategies of achieving "Energy conservation in the building", and the second chapter discussed: requirements, importance and advantages of "university administrative building and energy conservation", then the third chapter dealt with: all types of roofs that achieve energy conservation, which are "sustainable roofs". After extracting the theoretical indicators from the previous chapters, from Then the practical aspect was implemented in the fourth semester: "Application of sustainable roofs in university administrative buildings" using a computer program for environmental simulation. As a result, the research reached a number of conclusions, the most important of which are: Energy conservation is a concept that is applicable in the hot and dry climate of Iraq sustainable roofs, and the high efficiency of the Intensive Green Roof and the Ponds roofs in improving the internal environment of the university administrative building in Baghdad is specifically by reducing the energy consumed for Cooling and heating, which is reflected positively in reducing energy demand and then saving it.

The world has gone beyond the realization that fossil fuels are a depleted energy source, that the earth is going through a global warming phase, and that it is important to find the necessary energy alternatives, with the least environmental impact, and to address energy consumption in the building sector in particular. Passive systems and their use, or combined with effective systems. due to the dependence of the Iraqi urban environment on the electricitySignificantly and the source of fossil fuel, it is important to find suitable solutions, especially in the summer because of high temperatures and increased drought, by taking advantage of the experiences of countries within this scope, and applied to buildings , Because the roof is the main source of thermal gain inside the buildings it is necessary to take the systems of cool roofs, which is a passive system in the roofing of buildings, contribute to improving the internal environment and achieve the thermal comfort of the occupants, the research problem was:"There is no clear conception of the possibility of applying cool roof systems in the local administrative buildings" and The objective of the research is to" clarify the importance of achieving the concept of conservation of energy and improve thermal performance through the application of cool roof systems in the administrative buildings in the urban environment of Iraq with a hot- dry climate, "and then ensure the research Two aspects,first one:The concept of thermal performance and conservation of energy in administrative buildings and the way of achieving energy conservation using cool roofs, while the practical side included: the handling of several global experiences of sustainable administrative buildings used cool roofs and indicate the impact of this system on the efficiency of thermal performance, The research concluded that it is possible to apply cool roofs in claimte of Iraq (hot-dry) because the cool roof has the ability to reflect a large amount of solar radiation falling on the surface of the roof, thereby reducing the thermal gain of the building and improve the thermal performance of the administrative building envelope, and as a result achieved Save energy within its spaces

Lots theories and researches have been researching and analyzing the principles of the sustainable architecture according to the international standards. However, Iraq, its architects, and specialists are still behind the possibilities of applying the accelerating global green architecture trends and sustainable criteria. Hence this research represents a sustainable analytical process to one of the most unique event in the Iraqi architecture which is "MUSTANSIRIAYA UNIVERSITY". This process called the integral sustainable design theory. The main point of this research concentrate on the importance of the objective behavioral successfulness of the University complex around the years and the creativity of the designer (Qahtan Awni) in adopting the heritage vocabulary and giving its sense of belonging to the environment in a contemporary modern architecture with local material. As a result, we can consider "Mustansiriya University "as a successful example of a sustainable urban academic complex from the idea that the connectivity in its part make the sustainable holistic picture. 2 1. Introduction As Ken Wilber † described the integral model as a coherent harmonization of all in together, in comprehensive perspectives, and methodologies [1]. This research paper tries to put Mustansiriya University in an analytical inclusive process to have all its parts to an interrelated sustainable approach. Its work with complexity of the integral sustainable design theory (ISD) to simplified Mustansiriya University in to four quadrants each one represents a stage of the University development. Starting with the designer quadrant which gives a state of Qahtan Awni s Education &Artistry, experience, early work, Practical Career Stages (Approaches). and passing through Al-Mustansiriya University Behavior as the second quadrant. Then going deeply into the system quadrant of the University and ending with the cultural intersubjective realities about the University. All this done by three main sources, the available books and information, frequent visits to the university and the sources approved by the Engineering Department at Mustansiriya University, and the questionnaire for (29 specimen), twenty of them (20) are random samples working in the university, and (9) of them are architectural students studying now at the university to give the real expression for the University life and see whether it is sustainable or not. So the goal of this research is measuring the urban sustainability at Mustansiriya University according to the four quadrants of the integral design theory. The research was based on the descriptive analytical approach through a brief overview of the theory of integral sustainable design theory and its development within the conceptual framework, moving toward the practical framework which consist of analyzing the four quadrants of the theory trying to measure the urban integral sustainability in Mustansiriya University context.
