Distributed throughout campus, NORESCO's energy conservation measures have saved over $5 million. These measures include the installation of numerous central chiller plants, over 300 kW of distributed generation, over 12000 lighting fixtures, over 150 motors, over 6 miles of underground steam and condensate piping as well as a campus-wide energy management steam that provides the feedback to the maintenance shops on the location of any potential heating or cooling problem.
In addition to installing four water tube boilers at the main steam plant, NORESCO added new pumps, motors, compressors and piping, and renovated some associated equipment. The Company also undertook a major redesign and installation of underground steam and condensate piping to the university buildings.
All work was performed with minimal disruption to campus activities. The construction effort was closely coordinated with the university's Buildings and Grounds, Capital Projects, Police and Fire, and other departments. The improvements included
Environmental Hazard Abatement and removal of all asbestos and conducting a lead abatement program within the more than 80-year-old steam plant.
NORESCO also removed underground fuel oil storage tanks and replaced them with an above-ground fully contained system.
Central District Heating Plant
Installing four new water tube boilers along with all associated pumps, motors and compressors and all new piping as well as connections for gas, water and electric utilities. In addition, NORESCO installed an emergency generator.
The project included first demolishing and removing all old boilers, piping and associated equipment, and renovating the plant's 175-foot-high stack.
NORESCO did not disturb the original stonework of the building exterior and operated the plant throughout the construction period.
Steam Distribution System
Redesigning and installing over 6 miles of new underground steam and condensate piping to the university buildings using state of the art pre-insulated welded steel piping systems for high energy efficiency and minimal maintenance. This includes adding new pumps within the buildings and new manholes.
Control System
Installing a new control system to sense changing heating requirements and automatically adjust plant output and the number of boilers on-line. The 2000-point campus-wide energy management system manages the energy throughout the campus. NORESCO also tested the entire network.
Benefits
With NORESCO's facilities management unit providing full service on-site and the operation of new higher efficiency boiler and steam distribution systems, the University of Rhode Island is benefiting from NORESCO's wide range of expertise in minimizing energy costs.
