A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
EcoReps conduct "Sustainability Week" on campus with several workshops scheduled each day. Facilities will send email blasts to campus on energy saving ideas or initiatives.
A brief description of energy use standards and controls employed by the institution:
NMU utilizes Johnson Control Metasys for the majority of building automation functions. The building automation system is utilized to control both lighting and HVAC infrastructure. NMUs in house energy management program adjusts HVAC and Lighting schedules for all applicable buildings to ensure all systems are running at the most efficient setting based upon occupancy and need. Schedules are reviewed on a daily basis to ensure accuracy and effectiveness.
In addition to effective scheduling, all systems have seasonally relevant set points (summer 74 ± 2 °F, winter 70 ± 2 °F). Occupancy sensors have been installed in initial construction for areas which have high occupant capacity.
In addition to JCI Metasys, NMU has also begun to utilize KGS Clockworks fault detection software on a number of buildings. This software monitors all data points within Metasys to determine any potential system issues that are or will cause excess energy usage. NMUs energy management staff monitor this software on a daily basis and report issues to the Trades department to correct both software and hardware issues.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
NMU has eliminated installation of all fluorescent, incandescent lamps, HPS, and MH where applicable. In event of lamp failure, LED retrofits are being installed where available or the entire fixture is replaced as needed. Renovation and new construction specifies only LED fixtures.
To date the NMU campus is approximately 15% LED converted and is anticipated to retrofit approximately 10% per year.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
A brief description of co-generation employed by the institution:
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
NMU utilized Johnson Controls in 2010 to perform retro-commissioning on all HVAC systems. All systems are reviewed on an annual basis to ensure there has been no drift in performance for these systems.
Steam Trap Surveys, Boiler and Chiller Tuneup/Testing are all completed on an annual basis as well to ensure optimization of these system and the most efficient output.
Any systems that are scheduled for repair or replacement (whether by age or in new construction) are reviewed for the potential of increased efficiency. NMU strives for LEED certification of all new construction as part of the push towards a more sustainable campus.
