We renovated three patient floors in the Galter Pavilion at Northwestern Memorial Hospital, which encompassed a total of 116,368 sq. ft. and included 89 beds combined. In all, we specified 13 commissioned oil paintings plus 93 posters and prints. The 13th floor unit was occupied by the psychiatry department which required us to work with a specialized group of physicians and nurses to make sure that all of our images were suitable for this highly specific patient population. We worked closely with the medical staff to develop large scale nature images printed directly to polycarbonate panels which were built into the wall structure and then back lit with dimmers. This groundbreaking concept uses these art panels as a therapy, adjusting the environment from day to night, thus treating the circadian rhythms as a combined therapy for these patients.
