Analysis of different walls and the building’s location impact on energy consumption and designing solar water heaters: case study of Andisheh city
As the main factor of countries' economic development, which are also needed by all generations. In recent years, the issue of energy supply has been one of the significant challenges, the main reason for which is dependence to the limited supply of fuel. The way to end this problem seems to optimize energy consumption and re-switch to renewable energy. In this research, a building in the new city of Andisheh is analyzed considering environmental conditions and geographical directions using Carrier air conditioning software, and its thermal and cooling loads are examined for two different compositions of external walls. After selecting the optimal mode, the building is rotated 45 degrees clockwise, which by examining eight different directions, the minimum and maximum heating load required are equal to 124502.8 and 129579.3 kcal per hour and its cooling load were equal to 53.53 and 55.44 tons of cooling, respectively. In the second step, in order to use renewable energy considering the average daily radiation of 5.2 kWh in the new city of Andisheh, the project of hot water consumption using solar energy led to savings of 18945.16 Cubic meters of natural gas per year. The economic study of this issue shows that the return on investment of solar water heaters is 11.26 years, which is not cost-effective in the current economic situation.
