A brief description of energy use standards and controls employed by the institution:
The University has a Central Building Automation System (CBAS) which provides the ability to create discrete building and system operating schedules to reduce energy consumption. The CBAS system is implemented across over 87% of the campus. This system is used to match the operation of a facility’s HVAC systems with its occupancy patterns. Discrete scheduling is performed in all spaces where possible. Additionally, in newly constructed or renovated spaces, occupancy sensors are employed to enhance the energy conservation of both the lighting and HVAC systems by setting back unoccupied spaces. Additional strategies including discharge reset, CO2 control, and a zero dead-band control of space temperatures between 70 and 75 degrees F is managed by this system.
A single system is installed with a single front end which is under the purview of the Utilities Department. This Invensys system provides energy managers with the ability to tighten fan system controls. Building Managers work with our energy managers to adjust schedules for special events rather than a general expanding of schedules to cover a wide array of events.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
All existing campus exterior lighting has been retrofitted to LED lighting and has been established as the standard moving forward for new applications. They are also being used in applications indoors where there is an energy efficiency opportunity and where the lighting capabilities are appropriate. This has included projects in conference rooms, offices, athletic facilities, and lobbies.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Three geothermal well fields located under the East Quad, Ricci Fields, and the parking lot south of Notre Dame Stadium provide water heating for the Walsh Family Hall of Architecture, Ricci Band Rehearsal Hall, Pasquerilla Center, and Dunne, Flaherty, and McCourtney residence halls. The new geothermal systems at the East Plant and south of Notre Dame Stadium also provide chilled water that is piped to the campus-wide chilled water distribution system to be used where it is needed on campus.
A brief description of co-generation employed by the institution:
Five steam turbine generators, of which two are backpressure and three are extraction type, are used to co-generate electricity with the waste heat being used to heat campus or drive turbine-driven chillers to cool campus.
