The benefits of green building practices include a lower and more efficient use of energy, water and other resources, improved health and safety standards for the building residents, as well as reduced environmental impact, through less waste-production and pollution. Jordan limited and costly supply of natural resources, our future must be a sustainable. Jordan is one of the highest in the world depending on foreign energy sources , with 96% of the country oil and natural gas imports from neighboring middle eastern countries . This full reliance on foreign oil imports consumes a considerable amount of GDP in Jordan. The government of Jordan had established a renewable energy target equal to 7% of the energy mix by 2016 and 10% by 2020 as part of its 2007-2020 Energy Strategy. The plan calls for up to 1,000MW of wind, 600MW of solar and 50MW of waste-to-energy to be brought online by 2020. It lies in the hands of architects to reduce the effect of the construction because building construction contributes to around 41% in the carbon emissions and electricity use. The construction sector represents the major share of the energy consumption in Jordan consuming 45% of electricity. The objective of the study is to convert Al-Isra University to be a green building. To achieve this object surveying literature to know what has been done in this field, a comprehensive literature review has been done then investigating the energy levels consumption in XV Al-Isra university ,followed by design and analysis for electricity, design and analysis for cooling and heating, replacing traditional materials with green building materials, finally comparing the sustainable alternatives wing economical engineering analysis for selecting the best alternatives. Results of the engineering economic analysis of the five alternatives showed the alternative is installing a pv system which will save 10,577,250JD over 25 year so, it is recommended to apply the results and recommendations of this study and working hardly to convert Al-Isra University to be a green building.
