Residential and commercial buildings are responsible for almost 50% of the total electricity consumption in Egypt. This percentage is expected to increase due to the global warming effect. This work deals with the cooling energy use reduction strategies for residential buildings compatible with the Egyptian market accounting for the global warming effects. A study in the Egyptian market was done to explore the best available technologies in the Egyptian market. A series of dynamic simulations were executed in each city to optimize the building envelope using the best available technologies to reduce the cooling needs. Financial, energetic and environmental factors were taken into consideration, and comparative analysis was done to assess the best alternatives. The double wall with air gap and insulation on the outside was found to be the best alternative in all the cities. Moreover, simple measures to further reduce the cooling energy need were explored, such as the usage of more efficient lighting and night ventilation. This work led to an average reduction of 40% in the cooling energy needs and CO2 emissions across the three cities, with a maximum discounted payback period down to 6.3 years. Future weather files adapted to climate change were generated, and the selected passive strategies were tested to assess the validity of such strategies in the future. The cooling energy needs are expected to increase by 39%, while the peak cooling loads are also expected to increase by 23% by 2080, rendering the current installed HVAC systems undersized.
The development of existing technologies and the emergence of new technologies aiming at the total decarbonization of the buildings sector by 2050 requires and encourages upskilling and reskilling of existing professionals as well as the development of new subjects from higher education courses to be able to respond to the demands of these challenges. In responding to those challenges, the main objective of the research is to design, implement, and evaluate a novel, integrated, and transnational educational approach aimed at equipping professionals and students in the construction sector with the necessary skills to achieve sustainable and energy-efficient buildings. This study aligns with the European Union’s 2050 decarbonization goals by developing innovative methodologies that address the multidisciplinary challenges of sustainable building design, operation, and renovation. The proposed educational approach was developed in the framework of an Erasmus+ project entitled “Training for Sustainable and Healthy Building for 2050 (BUILD2050)”. Six higher education institutions from five European countries joined forces to create transversal skills in the building sector knowledge for emerging challenges through an integrated training composed of eight training courses for students and professionals of the construction area. In this work, the pedagogical approach used to develop the course contents, curricular development issues, technology, and infrastructure, as well as student support, the results obtained from the evaluation carried out after the pilot training of the eight training courses, and best practices and lessons learned, are presented and discussed. The courses’ learning objectives, the learning material, and the assessment activities were well-accomplished. However, based on the feedback of students and teachers, some improvements for future editions of the courses are required.
