Economic feasibility of implementing solutions to reduce energy consumption in Naja buildings (Case Study: tropical areas)

Given that the government intends to serve out the second phase of the project is targeted subsidies And also one of the most widely used program, energy agencies and state enterprises are most common, In this paper, we explore economic solutions to reduce energy consumption Jask for residential buildings that are owned by Iranian police (as the case study), pay. In general, one of the sources of energy waste in buildings, the external wall of the building is Use insulation and double-glazed windows can be effective. Firstly, the amount of energy wasted in buildings calculated The insulated state in both night and day compared Finally, calculate the difference in costs between state and non-insulated and insulated building Using Excel for Engineering Economics and Economic Assessment strategies are discussed. Calculations show that the cost optimization measures Jask optimization and building insulation to reduce energy loss, which is followed by most of the cost benefit makes. Taking the annual inflation rate of 10% and 15% to the cost of electricity, cost less than 39.16 and 44.31 percent interest rate there.
