Designing and Application of Solar Active Systems for Hakim Sabzevari University: A Case Study of the Dining Hall

In this paper, on the basis of Green Comprehensive Plan at Hakim Sabzevari University of Sabzevar, Iran, the application of active solar  systems for the dining hall is evaluated. The impact of solar systems and energy management designed for this hall on energy consumption and environment was investigated.This study measures the electricity and thermal energy consumption of the dining hall , proposes some new efficient lighting systems for rational usage and calculates energy consumption based on new technologies. Further, it evaluates renewable energies available in the region such as solar energy that includes hybrid photovoltaic/thermal panel and one ended evacuated tube collector systems for providing energy requirement. Then roof top and façade installation for solar collector and photovoltaic/thermal panel are chosen. Modified Angstrom equation, sunshine hours, mathematical relations and models are used to determine solar insolation. For these systems, the required area, rate of energy saving, pollutant reduction, and payback time are calculated. Results show that 85 photovoltaic panels are needed for providing 9898.2 Kwh/year electric energy. In addition, 36683 Nm3/year natural gas saving and 87.6 tone/year pollutants are reduced. The payback time for the system based on internal energy carrier and export electricity price is 21.3 years  and 3.9 years respectively.
