Other studies on building design and performance compared the new LEED healthcare certified children’s hospital, which had
incorporated additional specific features such as improved daylight, green roof, healing gardens, private patient rooms, to its
previous traditional structure. The impacts of the built environment on hospital’s performance and on patients and occupants was
also studied. The study concluded that following the move into the new LEED-certified building, the children’s hospital reported
significantly improved productivity, quality of care, and staff satisfaction, and reduced utility use per square meter, while their
expense per patient in bed remained stable during this time
