... = pressure loss reduction (31 kPa) and RS = energy consumed for every additional increase in pressure (0.5% per kPa). Therefore, SP is approximately 2.25%. Thus, the annual energy savings can be calculated using Eq. (5) and multiplying by the SP. Hence, AES = E c × SP AES = 10...

...Osama M. Selim; Mohamed Abousabae; Alaa Hasan; Ryoichi S. Amano Energy audits can identify energy consumptions, energy costs of the facility and evolve to develop measures to maximize efficiency, optimize supply energy, and eliminate waste. This paper investigates the potential energy savings at 20...

... achieved the highest GJ energy savings within the studied industries. Lighting, motors, compressors, and heating, ventilation, and air conditioning (HVAC) were the most contributing industries in a total of 547 recommendations. This study could be considered as a guide for plant managers, energy...

... measurements have been made, and energy, mass balances, and exergy analysis have been formed. Then, the efficiency of boiler, potential energy saving options and savings quantities, investment costs, and payback period for normal operating conditions have been calculated from the energy and mass balances...
