Pathfinder is providing mechanical, plumbing, fire protection engineering and energy modeling for the renovation of the historic 76,000 sq. ft. Crosby Hall, housing classrooms, studio and office space for the School of Architecture and Planning. It originally housed the School of Business Administration (School of Management). This project is being designed with a Deep Energy Savings Retrofit target of 50% energy reduction relative to the building’s existing consumption and the goal of LEED Gold certification.
Mechanical design includes a new HVAC system with risers and horizontal ductwork, air handling units and DDC controls to connect with the existing campus system. New chilled water distribution piping, pumps and controls to supply chilled water to new air handling units and terminal cooling units will be provided. The Campus chilled water system serves the basement of Crosby Hall. A new steam to hot water heat exchanger system with pumping, controls and distribution piping system will be equipped. In addition, the steam coil in the basement AHU will be replaced with a new hot water heating coil.
Plumbing and fire protection design includes a new domestic water and sanitary distribution piping to new fixture locations, a gas fired water heater for domestic hot water system and an automatic sprinkler system on floors above the basement. New exterior perimeter drainage systems will address water infiltration issues in the basement.
