Egypt is actively working towards developing the use of new and renewable energy sources. This commitment is evident in Egypt's participation in the COP27 climate conference, where it aims to maximize the utilization of solar energy and explore new prospects for green hydrogen. Egypt strives to be at the forefront of renewable energy adoption globally. To achieve these goals, it is essential to focus on two main aspects: developing plans and strategies for incorporating new and renewable energy in newly constructed buildings and enhancing existing facilities by studying how to implement and measure the effectiveness of renewable energy utilization. This involves assessing the expected energy savings and evaluating the efficiency of renewable energy systems in the operational phase.
This research emphasizes the importance of applying the principles and steps of value engineering to evaluate the effectiveness of replacing the current energy system with a renewable system and the potential energy reduction. A case study of a hotel in Sharm- El Sheikh Governorate is discussed in this research. The value engineering approach is applied by gathering information, forming a team to analyze this information, and conducting functional analyses. In this step, the operating costs are studied, revealing that they are high, mainly due to energy consumption and the use of fuel in boilers for water heating, resulting in environmental pollution. The next step in the engineering approach is to provide solutions and innovations, studying their feasibility, cost, and the achieved savings potential.
