Evaluating the effect of modern technologies to supply energy of buildings using new energies

Given the limitation of fossil resources to supply energy to buildings, recent years have seen arevival of interest in new technologies that produce the energy using new forms of energy in manydeveloped countries. In this research, first the potentials of new energies in Iran are discussed andthen based on case studies undertaken in a building in Tehran, the effects of utilizing new solarenergy technology for supplying the energy of buildings are investigated. Then, by analyzing thedata recorded over a four-year period, the technical performance of this system is investigated.According to the experimental operation plan, this system requires an auxiliary heating circuit forcontinuous operation over a year. Also, in the economic analysis, real conditions are consideredand the results are recorded based on long-term data. Considering the purchase and commissioningbuilding, supplementary energy consumption, etc. a comparison is drawn between the costs ofusing a solar water heater in a residential unit with the energy costs of a similar unit equipped witha conventional gas water heater. Given the current price of energy, using a solar water heater inthe country will not economical, but considering the global energy prices, this system will have areturn on investment after ۴.۵ years. It also produces ۸۱% less pollution and saves about $۲۱.۵ onenvironmental pollution cleanup.
