- ItemASHRAE Type 2 Energy Audit for Rafidia Hospital(2023-07-09) Ziad Tuffaha; Majed TayyemProject Description The team members of the project consisted on two students, Ziad Tuffaha and Majed Tayyem, with Dr.Mohammed AlSayed being the supervisor. The project was an energy audit for Rafidia hospital, which is one of the largest hospitals in the West Bank, following the ASHRAE Type 2 audit methodology. Energy audits are a method to decrease energy consumption and increase energy efficiency without disrupting the output or quality of life of the audited establishment. During both semesters, numerous visits to the hospital were taken. During these visits, the team members got familiarized with the site, collected data, and used energy management tools to collect more information and readings. Some of the tools used include a flue gas analyzer, multimeter, and power analyzer. After the visits and the data collection, the data was analyzed to find the best saving opportunities for the hospital. Moreover, each saving opportunity had an economic evaluation conducted, and the most feasible were selected. The identified saving opportunities were heat recovery from the which is achieved by rerouting and utilizing the wasted heat from the oxygen production compressors. This opportunity can save 25,351 NIS, and 11.4 tons of CO2 annually, with a very short payback period of 8 months. The second identified opportunity was applying overall boiler maintenance to the steam boiler, which will result in savings of 95,922 NIS and 41.4 tons of CO2 annually, with a payback period less than 6 months. The third identified opportunity was adjusting and increasing the load factor of the washing machines. Finally, information management and tracking systems have been recommended as there is a scarcity of data in the hospital.

- ItemAssessment and Redesigning of HVAC system for Al-Rawda Complex(2023-07-03) Abdullah Alshelleh; Dunia Lahham; Mohammed FaourAbstract Rapid growth of industrial, and huge growth of population have led to tremendous energy demand in Palestine in recent years. Heating ventilation and air conditioning (HVAC) are among the most energy consuming systems in the world, therefore, these systems must be designed and operated effectively. The main idea of the project is to assets an old heating and air-conditioning systems at Al-Rawda Complex. Moreover, a new efficient HVAC system is proposed and evaluated economically and environmentally. The proposed new system is suitable for installation and retrofitting at the studied building taking into consideration the age and function of the building. After reviewing different HVAC systems and analyzing the targeted building, it was found that the variable refrigerant flow (VRF) HVAC systems the best. Among the methodology was calculating the thermal loads of the entire building, including the mosque and the dispensary, in addition to making a design and economic feasibility calculations for three different scenarios. The third scenario was chosen as the most appropriate, realistic and reliable based on several factors.

- ItemAnalysis of Thermal Energy systems at Al-Hijaz Company(2023-06-13) Mohammad Abdelhalim; Monther QrariaAbstract This report presents two separate studies focused on energy efficiency in the food industry. The first study analyzes the thermal energy systems at Al-Hijaz Chocolate Company in Palestine and proposes strategies for reducing electrical consumption while maintaining efficiency. The study includes a feasibility analysis of proposed strategies and emphasizes the importance of renewable energy sources. The second study outlines strategies for reducing energy consumption in a factory, including replacing filtration fans by heat recovery units, installing a VRF ducted system, and adding a VFD controller to the chiller system. Economic feasibility studies were conducted for each strategy, and the report concludes that implementing these changes could result in a 20% reduction in electricity costs for the company. The document highlights the importance of energy conservation and sustainability in the industrial sector and provides references for further reading. We recommended this study for applying to get fiscal profit by saving energy consumption in the thermal system. Which the total investment is 165000 NIS, it will save about 34000 NIS per year, simple payback period 4.7 years. So it’s economically feasible to apply.
