In order to provide rain and snow protection for the generator and power transformers on the roof of this Chicago high-rise, Evanston Awning designed a canopy and curtain system that encloses the power equipment, yet allows the curtains to roll up for maintenance. All components had to be brought to the roof via a service elevator, which stopped at the floor below. From there, the crew pulled the system components through the elevator ceiling hatch onto the rooftop deck.
