Abstract: The implementation of solar panels for a green building in Jordan to generate solar energy and to support the electricity supplied by the national grid is presented in this study. The photovoltaic panels used generate approximately 7.2 kW of electrical power, which is used for office lighting. RETScreen software and computer simulation is used for the analysis of renewable energy technologies. The Energy Model worksheet is used to evaluate the proposed case system, which is the photovoltaic one. The result showed that the project cash flow is positive. The annual energy saving is found of 9315.61 kWh, which will annually eliminate 920.7 tCO2 of GHG. These findings support strongly the implementation of a local residential photovoltaic small project in Jordan, taking into consideration the escalating oil and natural gas price, and the decrease in photovoltaic technology cost.

Keywords: Green building, energy model, RETScreen software
