One of the pillars of architecture is modern environmental building technologies, in which the modern architectural theories seek to achieve the environmental compatibility in between building materials and the environment. This is done through the use of modern environmental technologies and treatments in buildings in projections, façades, and sectors. Facades of buildings using modern environmental architectural technologies and treatments allow an increase or decrease in lighting, ventilation, and temperature. It is the conditions of internal spaces, which require the architectural designer to consider when using modern environmental architectural technologies and treatments. This achieves compatibility with climatic variables throughout the whole year. Therefore, the research aimed to identify the applications of modern environmental technologies for building envelopes, how to achieve thermal comfort for users, and the extent to which it rationalizes energy consumed in achieving thermal comfort. To achieve the goal of the research, the study analyzed the covers of seven buildings, in terms of modern environmental technologies. An analytical comparison was also made between the study cases to determine how these technologies achieve thermal comfort. From which, it became clear the extent of the impact of the applications of modern environmental technologies on the case studies in obtaining a built environment characterized by thermal comfort suitable for users as well as the extent of rationalizing energy consumed in achieving thermal comfort in the internal spaces of buildings.

This paper presents an experimental investigation to clarify the behaviour of reinforced concrete square columns strengthened using ferrocement jacket. Strengthening using ferrocement jacket is relatively a new technique, which has a high strength/weight ratio, good resistance to cracking and impact loading, acceptable resistance to fire, and more resistance to corrosion than traditional materials. Ten reinforced concrete short columns with nominal cross-sectional dimensions of 200 × 200 mm with a total length of 1200 mm were cast and tested under axial loading until failure. The main parameters in this study were the number of layers of wire mesh, type of wire mesh, and the cement mortar strength. The results showed the effectiveness of the ferrocement jacket in improving the column capacity and reducing the vertical and lateral deformation. The results from the experiment were compared with the theoretical results obtained from the modified ECP 203 and modified ACI 318 equation codes.

The main goal of this study is to undertake the three methods of life cycle assessment (LCA), the environmental performance (EP), and the building information modeling (BIM) to determine the environmental performance and impacts of two window frame materials: aluminum and wood. This study has been carried out in a proposed project at the Assiut University campus. The LCA has been conducted by assessing materials and processes involved in manufacturing the two window frame types using the SimaPro. The LCA scope of this research covers from cradle to the gate with a designated system boundary. The network flow has been drawn to produce one kilogram of aluminum and wood; the quantities data were gathered from the BIM (using Autodesk Revit). Selecting the database is carefully picked from the Ecoinvent dataset to be closer to Egypt's manufacturing processes. Afterwards, the IMPACT 2002+ with midpoint and endpoint calculations has been used. Finally, the LCA results have been compared with the EP results (using DesignBuilder) to determine the best choice between the two materials. The integration analysis shows that the aluminum industry has higher negative environmental impacts and environmental performance than the wood industry. The total midpoint results of the two materials are found to be 29.6 for aluminum, and 7.57 the wood. Turning to the endpoint results, human health and resource depletion impacts are the most significant results. The human health scored the highest value, with 13.9 for aluminum and 3.51 for wood. A novel framework for integrating LCA, BIM, and EP for a proposed building during the early phases of a project has been conducted in this study. The presented study can be used as a model for integrating comparative analysis on other proposed projects as the LCA applications in Egypt are scarce due to the absence of a reliable database. This study has introduced a value applying an approach to select the appropriate life cycle inventory database from the Ecoinvent dataset. The research findings contribute to choosing the most suitable window frame materials with the most energy-efficient effect and the least environmental burden. Moreover, it can help the concerned legislative bodies and the decision-makers.
