Patient Observation Rooms at a Children’s Hospital in Pennsylvania


A typical observation room is lit from the ceiling, in this case with linear slot fixtures and downlights. The light coming from the ceiling is high quality and functional, but it is unlikely to improve the patient experience.
The addition of LIGHTGLASS luminous clerestories in 16 patient rooms adds brightness, richness, and character. The patient will feel as if there is daylight entering their room, which is proven to improve moods and healing times. Because LIGHTGLASS™ is constructed like a window, with aluminum and glass, it can create a subconscious connection to the outdoors in a way that traditional lighting form factors cannot match. The dynamic-white lighting provides stochastic stimuli for patients, family members and staff who are spending hours without stepping outside.

“Since LIGHTGLASS is only 3.5” deep, it easily recessed into a standard 2’x4’ stud wall. This allowed every patient room to have its own window light so the hospital maintains a consistent patient experience.” – Stantec

The Result

Our mission at LIGHTGLASS is to improve lives with light. We are proud to know that at this very moment, a family going through a difficult time is at least a little more comfortable because of our work with Stantec and the hospital for children.
