Lawrence Convention Center are addressed with CURRIES hollow metal doors and frames, McKINNEY hinges, PEMKO weatherstripping and locking solutions from SARGENT. The world’s first green convention center was awarded a LEED Gold certification for its excellence in building environmental performance. The David L. Lawrence Convention Center incorporates many green technologies, including the use of natural ventilation, daylight sensors and carbon monoxide sensors, a water reclamation system that reduces potable water use by 60 percent along with roof skylights and walls of glass that produce diffused lighting and uniform temperature. The shape of the building captures natural airflow from the Allegheny River to help ventilate and cool the building. All of the green features incorporated into the 1.5 million square-foot building help reduce energy usage by 35 percent.
