Application of solar active systems at Hakim Sabzevari University, a case study, dining hall

In this paper, on the basis of Green Comprehensive Plan at Hakim Sabzevari University of Sabzevar, Iran, application of solar active systems at self service hall has been evaluated. Solar systems and energy management are designed for this hall and their impact on energy consumption and environment has been investigated. Electricity and thermal energy consumption of the dining hall was monitored and by measuring and calculating the required amount of electric and thermal energy in the dining hall. Renewable energies that were available in the region were evaluated and solar energy was selected based on the amount of radiation and sunshine hours to provide part of the energy needed. For determination of solar insolation by using the modified Angstrom equation reand sunshine hours using library resources, mathematical relations and models, and the results of numerical-analytical methods were studied. The region is technically and economically feasible to use solar photovoltaic devices to an acceptable level. The results show that the average monthly solar radiation in this region is 281 mega joule per hour per square meter and the area needed for solar collectors to supply all of the dining room s hot water is about .150 square meters and the area required to supply electricity for its lighting is 118 square meters
