Stantec & LIGHTGLASS Simulate Daylight in a Windowless Patient Space

Even before the pandemic, hospitals in major metropolitan areas faced a significant challenge: too many patients, too few patient rooms. A children's hospital in Philadelphia needed to create more space for emergency patients, and decided to construct an Observation unit nearby to monitor patients before they being released or readmitted. An administrative office portion of the building was selected to be the site of the new observation unit due to its close proximity to the emergency department. However, this administrative space was located in the core of the building, eliminating the possibility of having an exterior window for each of the sixteen patient observation rooms. Without the possibility of sunlight, the hospital design team knew they needed to provide a connection to nature and a circadian stimulus, as it is proven to improve healing times and contribute to the quality of life of everyone in the facility.

LIGHTGLASS windowlights were selected to create the experience of a 1'x8' clerestory window in every observation room. These clerestories are LED-powered, and programmed to change brightness/color automatically throughout the day to mimic the sunlight outside.  In addition to giving each patient access to daylight, it was an important design objective to give each patient an equal healing space, and hospital experience. The LIGHTGLASS windowlights are less than four inches deep, and recess easily into a four-inch wall partition. This meant that every room could have the same clerestory application, no matter its proximity to other patient rooms or common areas. 

^{“LIGHTGLASS was able to help us achieve the circadian stimulus values throughout the course of the day; it operates like daylight, and feels like daylight, and being able to do that in the core of a building is fantastic.”}

This pioneering application of circadian lighting and windowlights is a game-changer in biophilic healthcare design. Any space can now incorporate the experience of a daylit window, regardless of its proximity to the outdoors. This will benefit patients, family members, and staff alike, leading us towards a healthier future.
