Translucent concrete (TC) is a green and sustainable material allows the light to transmit through itself by means of plastic optical fibers (POFs) or resin material embedded in concrete components. This study highlights the compressibility characteristics of resin translucent cement mortar (RTCM) and the possibility of using this material in the construction of external walls to rationalize energy expenditure within the building spaces to create a green sustainable environment inside the building. Compressive strength characteristics of RTCM, compared to that of translucent concrete containing POFs, is investigated in this paper. Furthermore, it is required to identify a theoretical approach for using RTCM in external walls of the building and its relationship to energy conservation, and then determining the effects of its use through a practical study on a test sample with using Passive House Planning Package (PHPP) program in the field of energy to measure the amount of energy expenditure. It’s found that adding a small amount of epoxy resin (ER) to the plain mix will raise the compressive strength, any extra amount of the ER will reduce the compressive strength. Finally, the study proved the possibility of using RTCM, with high efficiency, instead of bricks in the external walls of the building because of its ability to rationalize the energy spent in the building compared to the bricks.

الوصف Today, energy has undoubtedly become a feature of the era in which we live, and the amount of energy consumed by an individual has become a measure of the progress of nations. It is an established fact that buildings consume high energy in all its life stages and with its various components, and most of the energy wasted in the building is due to its misuse or as a result of the wrong design of the building, which makes it draining energy significantly. The research problem is that the traditional techniques and materials used in buildings, have a specific impact on energy savings in buildings within certain limits. The research aims to use nanomaterials to provide thermal comfort in the building while rationalizing energy consumption without neglecting the architectural formation and aesthetic appearance. Therefore, an inductive and deductive approach was used to achieve the goal of the research. The research reached a group of nanomaterials whose roles varied between thermal insulation, the amount of energy consumed for lighting, or the extent of the impact of nanomaterials on global warming, and thus their role in the process of energy conservation in the building.

The growth and expansion of urban areas around the world suggest that the future of the earth is predominantly urban, especially in less developed countries. This highlights the dynamic nature of these regions [1]. In the last 200 years, cities have become the most important places where people live all around the world. By 2050, 68% of the world's population will live in cities, which is called urbanization. However, this will mean that another 2.5 billion people will live in cities by 2050, and most of this growth will happen in Asia and Africa [2]. Urbanization refers to the transformation of rural land into urban areas, which is caused by various factors such as migration, economic growth, population increase, natural growth, improved social infrastructure, and availability of facilities and services [3-6]. Urban growth leads to urbanization, industrialization, and land development, but these developments have adverse impacts on the environment, traffic, and population [7]. The complex factors affecting urban land have consequences for its development and economic activity, both in the past, present, and future. Urbanization and its expansion have altered land use and coverage concerning climate change [8-10], the loss of forests and agricultural lands destroying plant and animal biodiversity [11], noise, air and water pollution, thereby affecting the quality of life [12], changing the hydrological ecosystem [13-17]. However, changes in land use and cover have detrimental effects on natural resources and the socio-economic system both directly and indirectly [18, 19]. In developing countries like Iraq, urbanization is a significant issue, with most communit

Today we live in an era witnessing an increasing demand for energy at a time when the main sources of energy generation have begun to run out. Which is witnessing a significant increase in the amount of consumption, offset by the inability to meet the population's energy needs. It would be beneficial to reduce energy consumption in buildings to a more environmentally friendly level and to a more energy-efficient level, this paper evaluates the Mantosiva material in walls to reduce heating cooling loads. Using (block, brick, Thermostone block) walls and creating the models, which have been simulated by Passive House Planning Package (PHPP) and Hourly Analysis Program (HAP) programs. To do this, image analysis techniques were used, and the analysis of the models was described by the diagram parameters. Six types of walls were analyzed in two programs, Mantosiva was used as a replacement for the external plaster. The objective of this research is to study the effect of Mantosiva material on the energy consumption of buildings in Iraq and identify the amount of energy savings from the application of Mantosiva in buildings. PHPP and HAP were used to calculate the thermal loads and the amount of energy needed. The building is located at Longitude 44.44° and Latitude 35.44° in Kirkuk/ Iraq.
The Role of Green Architecture in Smart Cities

Since the last few years, the concept of" smart cities" has become a widespread topic in a variety of fields. The practice of sustainable development is to thank for this rise in popularity. The philosophy, physics, and aesthetics of ecologically friendly building design and construction are collectively referred to as" green architecture" or" green building." The goal of green design is to reduce the amount of resources used in the construction, usage, and operation of a building, as well as the pollution, waste, and emissions that result from these activities. Design and construction of buildings generatorbaes waste that is harmful to human health and the environment. In order to minimize these resource-efficient structures and negative effects and build environmentally sound, it is necessary to introduce, define, understand, and practice green architecture. There is a word for environmentally friendly architecture. There are many benefits to adopting the principles of" Green Architecture" and" Green Building" in order to better utilize the natural environment and renewable energy sources, and then to creating standards for energy efficiency in buildings. In this study better understanding about the relationship between green architecture and smart city concepts and their impact on each other have been studied, where this study focuses on the role that green architecture plays when planning and executing smart cities.
