Abstract
In this work, 13 different solutions for the optimization of energy consumption of a building located in the tropical city of Bandar Abbas are studied out via the EnergyPlus and TRNSYS (Transient System Simulation Tool) commercial codes. Then, the suggested solutions are economically studied and the most economically viable ones are proposed. Ultimately, an energy efficient consumption scheme is put forward with the approach of solar energy utilization. Results reveal that 9 out of 13 studied solutions are techno-economically viable; and by implementing these solutions the energy consumption of the building could be decreased by 81% up to 165624.1 kWh as well as preventing 63022.66 kg of CO2 emission.
Highlights
With the energy crisis turning into a global concern, solutions are sought for the energy issues
The results show that an inclination of 37° provides the highest annual useful energy gain
As Bandar Abbas receives a high amount of solar insolation, utilization of solar systems for HVAC and power generation is investigated for the building
Summary
With the energy crisis turning into a global concern, solutions are sought for the energy issues. Another passive application in this field is utilizing specific windows along with dedicated control devices In this way, both lighting, heating, and cooling requirements of the building could be enhanced leading to lower total energy consumption, as presented in [31] and [32]. Poppi et al [36] presented a techno-economic review of solar heat pump systems utilized in buildings. There are variety of studies on energy conservation of building, but there are no studies to investigate different solutions including modern technology such as using renewable energy for a specific environment condition such hot and humid climate and present the applicable solutions for this condition. In this study different solutions for energy reduction are investigated for reducing energy consumption of a building in Bandar Abbas city where have a hot and humid climate. Electricity can be regarded as the main energy source (fuel) of the building since cooling is conducted with compression refrigeration and the domestic hot water is provided with the electric water heater
