| dc.description.abstract | As natural resources are decreasing and environmental pollution is increasing, the buildings that play an important role in this problem should be constructed sustainably so their affects are kept to a minimum. Hospitals operate 24 hours a day and 7 days a week, therefore they are one of the largest energy consumers. Hence designers have started to design healthcare facilities according to the Leadership in Energy and Environmental Design (LEED) criteria, believing that it will reduce waste production, energy consumption and increase patient satisfaction by creating brighter and less stressful facilities. To understand if the claims are correct or not, this thesis first studied the results of the patient survey, Hospital Consumer Assessment of Healthcare Providers and System (HCAHPS), undertaken at most of the hospitals in the U.S., and compares the results to LEED and non-LEED certified hospitals. To find answers for the claims related to the financial benefits, this thesis compared three financial indicators; cost of operation of plant, profitability, and inpatient revenue. In the cases where there is a large enough sample size, a t-test is used to compare two groups, however when the sample size was not large enough, two groups are compared based on their means.
For the cost of operation of plant and profitability, non-LEED certified hospitals are performing better. However, the patient satisfaction and inpatient revenues are significantly higher at the LEED-certified hospitals. | en |
