A Framework of Economic and Environmental Assessment of Solar Energy Water Heating System for Public Buildings

Abstract

Solar energy is a common practice in hot water production. In particular, the efficiency of the use of these systems has increased with the increase of collector efficiency. However, the effectiveness of the systems is also linked to the economic analysis as well as the effective project process. In this work, a framework was been established in the public sector with important user characteristics. In this study, collector optimization with solar energy as a hybrid system was made for the hot water requirement of the reference gym. In the annual heat demand analysis and with the developed mathematical model, it has provided savings of approximately 83.24%. In the analysis carried out, the annual recycling period was estimated to be about 4.24 years for fuel oil consumption and 8.82 years for natural gas. At the end of the study, associated annual CO₂ emission savings were calculated, and some suggestions were made to the public administration.
