Marriott Crystal City

Energy Efficiency & Privacy


The engineering team at the Marriott in Crystal City struggled to eliminate guest complaints of excessive heat and glare on the mezzanine level which included meeting rooms, hallways, and exercise rooms.


Again, HITT Contracting, one of the top 100 largest general contractors in the United States, counted on N.G.S. to be their turn-key window film solutions provider. After a series of sample installations N.G.S. furnished and installed HanitaTek OptiTune 15 to provide the best solution for mitigating excess solar heat and glare while minimizing interior reflection. Due to the positive experience they had with N.G.S., the engineering team has requested an estimate to protect the guest rooms.
