This paper concerns the simulation study of a mathematical model of the solar pond performance for collecting and storing the incident solar energy on the Karbala city (32.616° N, 44.025°E) in a form of thermal energy in its lower layer. It was found that there are several parameters affecting the amount of stored energy. The most effective factor is the amount of incident global radiation on the pond’s location. Therefore, a program in the FORTRAN language was established in the first stage to calculate incident solar radiation and the second stage to solve the One-Dimensional Finite Difference Method for heat transfer equations by using the arrays dimension. Various data for incident global solar radiation were in high agreement with NASA’s published data for Karbala city. Additionally, the obtained data of temperatures inside the solar pond were very similar to the published physical and experimental data of solar ponds.

The Salinity Gradient Solar Pond (SGSP) can be an effective way of capturing and storing thermal energy from incident solar radiation. The concept of using the SGSP to provide cooling or heating air for buildings models is studied. The idea seems appealing for a number of reasons, the design study shows it to be technically feasible and provide in the cost of electricity. The simulation program in FORTRAN is designed to investigate the possibility of the SGSP for cooling and heating of the models of the buildings in Karbala city, Iraq (32.62° N, 44.03° E). The obtained results have been shown the SGSP could be used for the cooling and heating loads during all hours of the simulation time and to meet 100% of the cooling and heating air the SGSP needed is 4-5 times the area of the building model. Keywords: Salinity gradient solar pond, cooling and heating air, solar thermal energy, and FORTRAN Program.
