The current study aims to investigate the feasibility of integrating rainwater collecting and solar photovoltaic (PV) systems in the car park of the hospital in Mosul, Nineveh Governorate, Iraq to promote sustainability, cost savings, and resource efficiency. The proposed system utilizes two types of steel structures: Type 1 with a level slope and Type 2 with a 25° tilt to optimize energy production and collect rainwater for irrigation and cleaning. For this purpose, RETScreen and SAP2000 software were utilized. For both types of structures, the Z-section design was determined to be the best feasible choice to offer stability, strength, and efficiency under a range of load conditions, including seismic and wind forces based on the SAP2000 software. Besides, the RETScreen software results demonstrate that Type 1 outperforms Type 2 in terms of financial viability and energy output. Consequently, this hybrid system offers a sustainable method to reduce reliance on conventional energy and water sources while providing significant financial benefits, making it a feasible option for urban infrastructure projects.

摘要

The current study aims to investigate the feasibility of integrating rainwater collecting and solar photovoltaic (PV) systems in the car park of the hospital in Mosul, Nineveh Governorate, Iraq to promote sustainability, cost savings, and resource efficiency. The proposed system utilizes two types of steel structures: Type 1 with a level slope and Type 2 with a 25° tilt to optimize energy production and collect rainwater for irrigation and cleaning. For this purpose, RETScreen and SAP2000 software were utilized. For both types of structures, the Z-section design was determined to be the best feasible choice to offer stability, strength, and efficiency under a range of load conditions, including seismic and wind forces based on the SAP2000 software. Besides, the RETScreen software results demonstrate that Type 1 outperforms Type 2 in terms of financial viability and energy output. Consequently, this hybrid system offers a sustainable method to reduce reliance on conventional energy and water sources while providing significant financial benefits, making it a feasible option for urban infrastructure projects.
