... Solar water heating is another way to generate hot water and at the same time eliminate the cost of electricity or fossil fuels and eschew any environmental impact that may occur [9]. The solar water systems comprise of a collector which absorbs and transfers heat from the sun to water and it is stored in tank [19]. The solar water system is reliable and has low maintenance system because it is stationary and have few moving parts. ...

This research presents thermal building and renewable energy integration: A review of modeling approaches and procedures. Past literatures shows that buildings consume 40% of energy from heating, cooling and fossil fuels. Little efforts were made in the area of combining renewable energy sources and integrating them into buildings. This research tends to offer solution to the problem of CO2 emissions and the amount of environmental impact emanating from over dependency on fossil fuels and other sources of electricity generation by mixing renewable energy resources and integrated into buildings using Nigeria as case study. From the results obtained, a total of 17,303 MW was targeted for the year 2010. It is however, unfortunate that even as at 18th October 2015; Nigeria's peak electricity generation was less than 4,500 MW. It would be very difficult to achieve a total of 131,122 MW of electricity projected for 2030 in the country if the country does not adopt renewable energy mix.
THE RELEVANCE of the study lies in the fact that air conditioning systems in Iraq consume more than half of the electricity generation. During the summer, when temperatures rise, the demand for air conditioning increases, resulting in constant power outages. Consumers are starting to use local generation - diesel generators, which increase environmental pollution. THE PURPOSE. Consider the problems thermal energy from the sun is an ideal solution for reducing electricity consumption, increasing the performance of air conditioners, ensuring continuity of power supply and reducing pollution from diesel generators and power plants, as well as saving energy and reducing the consumption of fossil fuels. METHODS. When solving the problem, a comparison of options for standard and (hybrid using solar thermal energy) air conditioning systems was used. In a hybrid system, thermal energy enters the system from a solar collector built behind the compressor. Thermal parameters and level of electricity consumption were calculated. RESULTS. The article showed that a hybrid air conditioning system using solar thermal energy is more efficient than a traditional system, as it increases the cooling coefficient by (38.9 - 46.3%) and reduces electricity consumption by (56.89 - 66.66). %). CONCLUSION. The use of a hybrid air conditioning system in the climate of Baghdad city with a vapor compression air conditioning system reduced the electrical energy consumption of the compressor and increased the performance of the system, which will lead to increased reliability of power supply and eliminate the need to use local diesel generators.
