For the last 10 years, the issue of green building movement had been growing in Jordan, due to the environmental and financial benefits, and since that Jordan suffers from the lack of resources, the concern of sustainable and green building developments has increased recently. Several buildings in the country had applied sustainable methods, but none of those buildings is a healthcare facility. Sustainable buildings had shown positive impacts on human health, and the environment. Taking into consideration that the healthcare sector in Jordan is important and that hospitals are large consumers of resources and they have high running costs, the Gardens Hospital was chosen as a case study. The methodology that was used is a descriptive-analytical one. The aims of this research is to evaluate the hospital according to sustainability standards in Jordan, then to give several sustainable alternative improvements. After that, economic analysis for the improvements was done to check the feasibility after implementing the proposed sustainable improvements on the building. The results of this research had shown positive profits for implementing the proposed improvements and the high value of the IRR which was found to be 34,6%, which means that the suggested improvements are feasible and effective. Another result which was found from this research is the importance of applying sustainable methods for all kinds of buildings due to their high benefits.
