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.

The adoption of green building technology has become significant for ensuring sustainable development; it has become the main step to a sustainable future. The designs for green buildings include finding a balance between comfortable home construction and a sustainable environment. Moreover, the application of emerging technology is also used to supplement existing methods in the development of greener buildings to preserve a sustainable built environment. The main problem of this research is how to tackle the environmental parameters balance based on new techniques that are being used for green building optimization. To mitigate the cumulative effect of the constructed climate on human wellbeing and the regular ecosystem, the most popular goals for green buildings should be planned. This can be achieved by efficient use of natural resources such as energy, water, and other resources and minimizing waste. This will contribute to the security of occupant health, enhancement of work performance, emissions control, and improvement of the environment. In the construction of green buildings, several criteria that may contradict, interrelated indistinct and of qualitative and/or quantitative environment are broadened to utilize. This paper provides a detailed state of the art analysis on improving existing practices in green architecture/building using analytical hierarchy process (AHP) techniques to tackle the environmental balancing values based on optimal strategies and designs by green solutions to help make the best possible option from numerous options.

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.

Thermal comfort is the result of a balanced of building frameworks adjusted to both the area of the structure just as the kind of air move performed inside the structure or the room of the structure. This article represents the Minia city as a case study based on the Mahoney tables method to validate the best design strategy in the hot desert bioclimatic region. Mahoney tables are a collection of referenced tables utilized in construction as a climate-appropriate design manager coupled with the meteorological data to include the right design recommendations. As indicated by the examination of the results that be gotten from Mahoney tables climatic characteristics, the design strategies were recommended. These recommendations can help architects bring forward a set of bioclimatic design strategies for buildings in Minia's environment to conduct thermal comfort with the help of the climate consultant tool. So, the Mahoney tables can assess the climate to be more accurately reflect the environmental conditions in the summer. Also, it can beware of the passive heating technique as natural ventilation used in the construction of energy-efficient buildings.

This paper studies the Egyptian building design strategies for different building envelope shapes based on the green building design using the DesignBuilder program by simulating the outdoor climate conditions depending on the Egyptian meteorological data. The simulated results are applied to Minia City as one of the hot-desert climate regions in Egypt. The research is performed on the hottest day in summer according to the analysis of climatic data overall months using the climate consultant tool. This research studies two main variables to characterize the quantitative relationships between the building form and the Natural Ventilation (NV) of thermal comfort to be achieved, which are mixed-mode maximum wind speed, and natural ventilation setpoint temperature. The research focuses on two output parameters, which are air velocity and pressure, relating to natural outdoor ventilation. The simulation findings revealed that the circle form offers the best case, which has a significant role in achieving thermal comfort that optimized the value between the two major parameters in building design, while the worst case is the U-shaped building based on the same two optimized values. Finally, the usage of natural ventilation, simultaneously with choosing the suitable building geometry, is principal for adapting the current outdoor air velocity and pressure, thus reducing the energy consumption of buildings. Practical application: This paper studies the relationship between building form and natural ventilation to achieve outdoor thermal comfort and its effects on buildings. The study assesses the wind speed and temperature parameters using the DesignBuilder tool. The study suggests a combination between natural ventilation and choosing the suitable building form to adapt the air velocity and pressure to reduce the energy consumption of the buildings.

Passive design architecture is attractive to all of us; however, due to the present energy shortage, architects and engineers are interested in developing creative solutions that depend on nature's resources. This study investigates the design strategies that affect thermal comfort in residential buildings in Minia City. The study examined the Minia climate using a psychometric chart and CBE tool based on 12 passive strategies to develop building design recommendations. These recommendations will give architects the necessary knowledge throughout the project design phase to assist them in using natural resources, reducing operational energy usage, and preserving thermal comfort using passive approaches.Although passive design has received little attention, it is crucial to know how natural systems that mimic the ecological systems on Earth perform. Climate type, adaptable thermal comfort, vernacular and contextual solutions, tools and evaluation techniques, microclimate, sun path, wind, rain, passive and active systems, and responsive forms are the main topics covered by the components of climatic design.
