    Recently, green structures turned into a huge path to an economic future. Green building outlines include finding the harmony between agreeable home living and a maintainable environment. Furthermore, the usage of modern technologies is seen as part of greener construction changes to make the urban environment more viable. This paper introduces an exhaustive state-of-art review and current practices to look for the ideal green arrangement’s models, procedures, and parameters utilizing the genetic algorithms innovations to help for settling on the most ideal choice from various options. The integrated Genetic Algorithm (GA) along with the Nondominated Sorting Genetic Algorithm strategy GA-NSGA-II is considered to be more accurate for predicting a viable future. The above methodology is widely relevant for its humility, ease of execution, and enormous durability. Besides other approaches, the GA was incorporated as well as the Neural Network (NN), Simulated Annealing (SA), Fuzzy Set theory, decision-making multicriteria, and multi-objective programming. The most fashionable methods are moderately the embedded GA-NSGA-II approaches. This paper gives an outline of the capability of GA-based MOO in supporting the advancement of methodologies of the techniques and parameters to find the best solution for the building decision-making cycle. The GA combined schemes can fulfill all the requirements for finding the optimality in the case of multi-objective problem-solving

    This paper discusses the effect of various climatic conditions that pertain to passive design measurements and their relationships with building configurations to improve indoor thermal comfort based on the different climate zones in Egypt to support Egypt’s sustainability agenda 2030. We find the most appropriate design settings that can increase the indoor thermal comfort, such as building orientation and shape. These settings can be modeled using DesignBuilder software combined with Egyptian meteorological data. This software is used accompanied by computational fluid dynamics to numerically assess the outcomes of different changes, by simulating indoor climate condition factors such as wind speed and temperature. Natural ventilation simulations were performed for four different shapes to create comprehensive dataset scenarios covering a general range of shapes and orientations. Seven scenarios were optimized to put forward a series of building bioclimatic design approaches for the different characteristic regions. The results indicated that the temperature decreased by about 3.2%, and the air velocity increased within the study domain by 200% in the best and the worst cases, respectively, of the four different shapes. The results of the study gave evidence that the configuration of buildings, direction, and wind speed are very important factors for defining the natural ventilation within these domains to support the green building concept and the sustainable design for a better lifestyle

    AbstractThe hydrodynamic features of Rosetta promontory are simulated numerically to minimize the outlet siltation problems. Many coastal structures (i.e. revetments, groins) are used to solve the erosion of the shoreline and siltation in the outlet. However, the shoreline along the promontory is still unstable and these structures did not achieve the expected results to reduce the problem where the erosion problem is shifted down drift. In this research three potential solutions were investigated. The first solution is to apply a soft approach in term of re-establishment of natural hydrologic conditions such as providing additional water discharge processes through diverting Burullus drains to the end of the estuary to achieve the nature and stable condition for the promontory. The second proposed solution is to reach the equilibrium cross section of the outlet by dividing the Rosetta outlet into two parts by constructing two 500m separated jetties. The third solution is to control the sedimentation in the outlet by constructing 450m length jetty attached to the eastern bank of the estuary. Numerical Coastal Modeling System (CMS) was used after tuning the model parameters to check the feasibility of the different proposed solutions on the stability of outlet channel. The study shows that an additional discharge of 47m3/s in the first scenario results in a stable outlet cross section suitable for navigation purposes but with limited effect on the erosion problem
