Cost and Use Reductions
●
●
●
●
NMU has saved over $25 million since 1973 with the
energy conservation program

space is up by 146.8%
Electrical use is down 1% while square footage of space is
up 77.7%
Water use is down 34% while square footage of space is
up 77.7% and irrigation programs have been initiated
Expanded Energy Conservation Focus
 Three focal points:
 Occupant awareness
 Capital improvements
 Operational savings
Occupant Awareness
●

Space utilization
Space Utilization
 2007 – NMU implemented College Net scheduling and
utilization software:

R25 – Inventory of campus spaces (classroom, offices, conference
rooms, etc.)



S25 – Course scheduling (automated course scheduling)
X25 – Space utilization analysis
“Web Viewer” – Online schedule view and request tool (used for
informal event scheduling)
 Why





State of Michigan reporting requirements
Facilities are the largest campus asset
Better manage/utilize existing space
Defer need for new construction
Reduce operational/energy costs
Space Utilization
(continued)
 Goals noted at December 2007 Board of Trustees
Presentation




Model “what if” scenarios for classroom buildings
Model space needs for enrollment growth
Benchmark current space utilization
Model changes to improve utilization
***NMU’s Opportunity for Operational Savings***
Space Utilization
(continued)
NMU established a Space Utilization Committee in 2008 with
broad representation of campus community.
 Committee Charge:
 Provide space utilization information and recommendations




that will help effectively manage facility space
Establish benchmarks for current space utilization
Develop utilization standards for academic, administrative, and
athletic/recreational space
Develop yearly space utilization reports for each campus
facility
Advise the administration on system access, data
enhancements, and utilizing system features and functionality.
Maintain and update system information and recommend
system and data enhancements.
Space Utilization
(continued)
 Committee accomplishments to date:
 Reviewed current space inventory
 Summarized best practices and generally accepted utilization
standards
 Analyzed two years of utilization reports
 Developed classroom scheduling recommendations

 Opportunity for Operational Savings:
 “Consolidation Scheduling” (65 – General Use Classrooms)
 Limit evening, Friday, and weekend courses to core buildings
where possible
 “Priority Scheduling”
 Zone buildings by mechanical systems. Coordinate class
schedules with mechanical system operation to maximize building
efficiencies
 “Hours of Operations”
 Consider reducing building hours of operations to be after last
evening or weekend class
Space Utilization
(continued)
Jamrich Hall:
 Fall 2009 – Consolidation Scheduling
 Relocated weekend courses to core buildings
 Closed building until 5:00 pm on Saturdays
 Turned back mechanical and lighting systems
 9 hours per week x 16 weeks x 2 semesters = 288 hours annually
 Estimated annual savings $14,000
 Future – Consolidation Scheduling (in addition to actions noted
above)
 Relocate Friday courses to core buildings
 Close building until 5:00 pm on Fridays
 Turn back mechanical and lighting systems
 12 hours per week x 16 weeks x 2 semesters = 384 hours annually
 Estimated annual savings $17,800


Establish scheduling/mechanical priority zones
Maximize zone capacity where possible
Relocate courses to other buildings where possible
Operate only occupied zones for evening classes
Reduce mechanical and lighting systems operation by
approximately 50%

University supports all informal activities placed in core buildings for
off-peak use
Mechanical systems scheduling tied to course scheduling – close
coordination between Registrar’s Office and Facilities Management
Some department controlled classrooms available for space
requests
On-line space request “web-viewer” available for space requests
University supports an evaluation/reduction in building hours of
operation
