The Earth-sheltered building type is spreading all over the world in the last decade as an eco-friendly building’s style, and as a passive energy saving technique. Most previous researches regarding this type are discussing the energy savings’ and measuring the “heating/cooling loads” reduction extent. This research is discussing the subject from the urban point of view, and the application’s possibility for the housing projects in the Egyptian deserts. Adopting the quantitative method followed by the qualitative analysis; the research quantified the results of a questionnaire survey, and used the chi-square test to analyze the significant results, in order to be able to generalize the results to the community. Followed by some urban design considerations and applicable recommendations related to this type according to the questionnaire survey results. The practical discussion argued the application’s possibility at the housing sector in the Egyptian deserts through discussing the motives behind thinking of the application in the housing sector at the Egyptian deserts; and the application’s optimal performance constraints. The research recommends using this type of buildings for housing in the developing projects of the new communities in the Egyptian western deserts, like ”Toshka”. Moreover, in the new touristic resorts, and in the small and middle-sized projects.

The evaluation of buildings in real conditions of use, or post-occupancy evaluation, is the systematic study of buildings with the objective of determining their performance once they are inhabited; it is a process of review and identification of successes and failures in order to improve the conditions of existing buildings and to feed future designs. Nowadays, the construction industry in Colombia does not have feedback processes regarding the operation of a building. The research presented below proposes the HEPO post-occupancy assessment tool, which is oriented to the analysis of buildings in phase of use, in terms of meeting the needs of the inhabitants, the consumption of resources associated to the use, and the conservation of the qualities of the materials in time. In order to verify the effectiveness of the tool, this is validated in five collective height housing projects in the city of Medell´ın, Colombia.

Sustainable development and sustainable housing indicators are a response to the trend of adopting sustainable development objectives, adopted by most countries, especially developed and less developed countries. It is difficult to implement indicators developed for a developing country context in other contexts with different social, economic and environmental conditions. Social sustainability is the most important priority regarding evaluating the housing development projects in the developed and less developed countries. Economic conditions is linked in many aspects to the social sustainability indicators. Environmental indicators are important, but the less developed countries in general has a very low environmental foot prints, this is because the industry sector is usually week comparing to the developed countries. This paper reviews the sustainable housing indicators, with a focus on United Nations reports and indicators developed for contexts similar to study area, without ignoring the most reputable indicators developed for developing countries context. The research came with a set of indicators reflects the social priorities of the new housing development in Sudan. A questionnaire participants decided the relative important of each indicator and also the importance of the parameters of each indicator. Developing a set of social priorities for Sudan will give extra efficiency in promoting and assessing sustainability in the study area. Description of the questionnaire results which reflects the national social sustainable housing development priorities are discussed. The researches came with a set of recommendations to enhance the social aspects for new housing development projects in Sudan. Using this set of priorities and recommendations will give extra efficiency in promoting and assessing sustainability in the study area.

The shortage of sufficient available fresh water resources in Jordan to meet water needs forces the nation to look for new water supply sources also to meet the increasing demand for fresh water. In this manuscript, a case study for designing, optimizing and implementing an off-grid water desalination system using photovoltaic (PV) power generation system is introduced. The system is installed on a farm in Southern Ghore of Jordan valley where the access to the grid is not reliable enough to guarantee the desalination of the amount of water for the farm’s irrigation needs. The study offers a framework to aid in designing similar pilot plants where the classic power generation prediction is greatly affected by the environmental conditions. An off-grid PV system with a total nominal power of 10.4 kWp was designed, procured and installed in the southern part of Jordan Valley near Karma town. The system operates the pumping system as well as the reverse osmosis based desalination unit. A measurement system has been collection relevant data like temperature, radiation, voltage, current, water quality, pressure, etc. continuously for the last 4 years. In this paper we will present the sizing procedure used, the system design and evaluate the design using the collected data of the run-time of 4 years. Data about the water quality and amount of desalinated water will equally be used to evaluate the system. The paper will end with recommendations to adapt the system design in different part of the Middle East and North Africa (MENA) region.

This paper presents the results of using a pilot-scale-constructed wetland as a tertiary treatment to the domestic wastewater by using local plants in Syria, aiming to achieve the Syrian legal standards of phosphorus and nitrogen emissions. This pilot plant consisted of tow types of wetlands.The emerged plants are placed in 3 tanks and followed by 3 tanks of free-floating plant, daily estimating the treatment of24.m3/day of effluents. The effluents were circulated in a vertical subsurface flow through a porous matrix of thick sand and gravel, in which the roots of the Arundo donax and Cattail (Typha sp.) and Bottomos (locally species Reed) were fixed. Monitoring of the pilot plant was performed through biological analyses. The flow bypassing through free-floating plant tanks will support removing the nutrients. The system offer a good degree of pollutant efficiency removal, especially for phosphorus (45% medium), TKN (80% medium), and NH4–N (60% medium).

There are numerous important human activity factors which cause drastic reduction of the population of migratory birds as well as resident birds in the Libyan coastal areas and inner land too. Resulting into the deterioration of the ecosystems which support life, urban health, and simultaneously causes loss of urban heritage and place identity. The urban sprawl has increased significantly over the past few decades as a result of population growth and economic activity. This rapid urbanization seriously invaded agricultural land and natural environment to the extent of endangering rural and urban landscape. In the absence of legislative regulations; this uncontrolled spatial development is threatening wildlife habitat. Therefore, we see how urban expansion has gone out of control in many Libyan cities to an alarming rate surmounting the increase rate of population caused by extensive economic policies. These policies lack an ecological vision of preservation of cultural and natural heritage which would have ensured the realization of healthy ecosystem and a sustained vision towards the future of rebuilding Libya. This paper aims to identify the relationship between built environment and natural habitat for migratory and resident birds. The paper is using archival research methods by drawing together mortality causes from various sources so that human related factors can be placed in perspective with one another and perhaps, eventually, with other mortality factors in future studies. The paper attempts to shed light on the dangers faced by these birds including those inflicted by human activities. Finally, the paper tries to formalise general outlines for presenting safer urban environment for birds in the city. A strategy for green buildings and sustained urban design in order to preserve the fragile natural landscape and the endangered biological diversity in our Libyan cities.

Exterior Thermal Mass (eTM) is known to improve building energy and thermal comfort performance. Despite its known benefits, studies to date have not thoroughly addressed the effects of eTM on building environmental performance by considering a wide range of influential factors and various climatic conditions. This paper addresses such a gap in the body of knowledge by conducting a comprehensive and detailed analysis of eTM impacts on residential buildings’ energy performance. Using quantitative research and simulation analyses, this study has found various trends of energy reductions and, in a few cases, energy increases depending upon the location of projects. In fact, the cooling energies are shown to increase of up to 4% for the scenario of 20 cm thickness wall in several locations. Aiming for better energy and design load scenarios, this research has also established the optimal eTM depth to help architects and engineers make informed design decisions with regard to building envelopes, which is particularly important for developing countries with similar climates studied in this paper, where the use of masonry materials is widely common. As for future steps, further exploration of cooling energy increase phenomenon, which was observed for several climates is recommended. Also, coupling eTM with code-required thermal insulation based upon specific climatic locations and evaluate their integrated performance can be considered.

This paper discusses and presents the implementation of a boost converter as power electronic interface to be used with the thermoelectric generator (TEG). The common application for such system is the battery charger. The boundary conditions for battery chargers include the charging current and battery voltage limits which have to be respected throughout the charging process, while the maximization of the power generated from the TEG is a global target that is desired to be met as much as possible. Coordinated control algorithm that collectively combines these constraints is the main focus of this work. Novel global control algorithm is proposed and verified in this paper with detailed analysis that shows the effectiveness of the proposed algorithm. Dual control loops for the voltage and current of the boost converter will be designed and analyzed to satisfy the source and load demands. Maximum power point tracking (MPPT) mode, power matching mode and voltage stabilization mode will be integrated in the control algorithm of the battery charger. This paper puts a schematic design for a system that harvests energy from a thermoelectric generator bank of a TEG1-12611-6.0 TEG modules in order to charge a battery bank of Samsung ICR18650 Batteries using constant current (CC) and constant voltage (CV) charging profiles.

Whilst sustainable construction relates to both a building’s structure and the use of proper life cycle processes, the selection of the most appropriate material/s is deemed a considerable undertaking. Throughout a building’s lifecycle that extends from design, construction, operation, maintenance, renovation, until demolition, the selection of sustainable material/s is a particularly crucial task for the development and establishment of such structures. Traditionally, there are three main materials for general construction: (1) Steel, (2) Concrete and (3) Timber. These materials not only influence the function within the structure, but also affect the operation cost and energy usage. Operation cost reduction and energy savings are typically elements of the sustainable construction sphere. However, in developing countries, there is a variety of highly critical factors, which can impact material selection as well as the long-term sustainability of the structure, including: Fire Performance, Environmental Impact, Structural Performance (strength and durability), and Functioning Capabilities. Accordingly, this paper will first compare the sustainability of these three key materials and then converse with appropriate processes for material selection. Attention will be given to the sustainable construction recompense associated with the different material selection factors. Doing so ensures a more sustainable built environment by means of an improved material selection process.

Sustainable development presents one of the most complex challenges in Egypt in particular of keeping up with the global march. According to what Egypt possesses of original cultural spatial components, the need has necessitated taking care of the investments, but in a sustainable way in the historical cities centers where its possession of cultural spatial elements with high economic importance. However, Egyptian historical centers have suffered from Degradation and dissipation of energies and capabilities resulting from the negligence of urban conservation projects, and its incompatibility with the ongoing social changes. The pathway taken by urban development have been considered as incomprehensive methods for all the levels of effect of the historical centers.These levels are the international, national and local levels with the Totalitarian goals for the city and the national economy which has been aimed at the methods of conservation of the urban in the domain of the historical area only. That narrow perspective hasn’t achieved an increase in economical and job opportunities, without relying on the attracting the investments and tourism that can achieve a change of the value of the targeted area from the actual value towards the highest probable value. The historic core is considered as an attraction for the tourism activities but in the centers of the Egyptian cities, the public realms are the outcomes of the undersigned remaining realms. Therefore, they cannot perform their function as public spaces expressing the local character, as they are the center of social relations and cultural product.
