Pathfinder is providing mechanical, plumbing and fire protection engineering and energy modeling for the total renovation of this historic 90,000 sq. ft. building. Marshall Hall was built in 1933 and has not undergone significant renovation in over 40 years. 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.
The project is decoupling from the district steam heat source. Marshall Hall will be equipped with high-efficiency condensing boilers. Additionally, the perimeter steam radiators, gravity unit ventilators, fan coil units and all steam and condensate piping will be replaced with a building-wide hydronic heating system with occupancy-based controls. All components are being sized for compatibility with a future geothermal-sourced heating system.
This project will provide cooling to all spaces via a new heat pump loop and ventilation will be provided through demand controlled energy recovery ventilator units. Occupancy sensors will tailor ventilation airflow rates to each space to maximize energy efficiency.
All lighting and power will be replaced in the building. New lighting will be energy efficient utilizing LED technologies. Historical light fixtures in the main lobby and spiral stairwell will be refurbished and relamped to be more energy efficient as well. A 100A 408/277V-3 phase-4 wire diesel emergency generator will be provided to serve the life safety loads in the building.
New telecommunication systems will be provided throughout the building. Additionally, a new fully-addressable fire alarm system will be provided. Card access and security systems will also be replaced.
