MODELING THE USE OF ALTERNATIVE ENERGY SOURCES AND TECHNOLOGIES TO REDUCE ENERGY CONSUMPTION OF A SINGLE DETACHED HOUSE AT ANKARA, TURKEY

G. Gugul, M. Koksal

Abstract: In this study, hourly energy consumption model of a single detached house in Ankara is developed using ESP-r. Natural gas is used for space heating, cooking, and water heating in this two-story 4500 square feet four-bedroom home. Hourly electricity and daily natural gas consumption of the dwelling are monitored for one year. The hourly space heating demand model is developed using the hourly climate, building envelope, and occupants' energy consumption behavior data. The estimated hourly heating energy demand of the dwelling is then compared with the actual measured heating demand to determine the performance of the model. Various energy saving scenarios are applied to the model to determine the amount of reduction in total energy consumption, associated emissions, and fuel expenditure. As for renewable energy scenarios, photovoltaic panels to generate electricity, ground source heat pump for space heating, and solar panels for domestic hot water generation are applied to the hourly model. Scenarios based on improving wall and roof insulations, and window glazing are also applied to the model for heating demand reduction analyses. These scenarios are evaluated based on annual energy demand, associated CO2 emissions, and fuel expenditure savings. The pay-back periods for each scenario are also calculated to determine the most appropriate scenario for this single detached dwelling to reduce annual energy consumption, CO2 emissions, and fuel expenditures.
