Each room has floor-to-ceiling windows to maximize both the stunning views and the flow of natural light deep into the core of the building. Studies have shown that patients exposed to higher-intensity sunlight levels perceive less pain and take less pain medication. Increased natural light exposure has also correlated to better management of stress and happiness levels, decreased patient length of stay and improved employee performance. This design feature earned international recognition in 2014 as one of the top 100 leading sustainability innovations by Scandinavian think tank SUSTAINIA.
