We are working on a new medical buidling (cancer center) and there is a gift shop off a large corridor close to the main entry. The owner wants the wall between the gift shop and the large corridor to be glass. The other three walls are partitions with a min STC above 50. Does the glass wall need to be above a 50 STC if it is adjacent to a large public corridor? We want to provide a visual connection to the retail space; however, don't want to loose this credit if at all possible. All othere occupied spaces in the 500,000+ sf building comply, so loosing the credit for one glass wall would be disappointing.

I really appreciate any feedaback that can be provided!
