The goal was to alleviate the burdensome cost of hot water needed for dishwashing and cleaning in this industrial building-turned-restaurant. The solution was to place two rows of south-facing evacuated tube solar thermal panels next to the skylights that were part of the original roof design. Cold water is heated as it circulates through the rooftop tubes, then returned back into the building, warmed and ready for use.
Since the restoration of this former hotel, more than half of the tenants’ annual hot water needs have been supplied by a solar thermal system, installed to keep energy costs to a minimum. Due to the building's landmark status, the eight new solar panels were required to be invisible from the front, so they were arranged at the back of the roof, facing south. Thus, the elegant facade remains intact.
