In Attendance: Mel Kotur, Otto Pohl, Steve Bruner, Matt Madden, Peter Belschwender, Hattie Baker
Notes prepared by: Hattie Baker
Introductions
Swim center usage
Purchasing power w/in the city. Swim center an example. Put together 5 years ago.
Identify waste w/in sector:
Most current: Library‐ largest building – energy estimations based on size as part of LEED construction.
Looked at daylighting components. Models generous w/ energy use.
Issues: air conditioning system not fully integrated w/johnson control system
Working w/engineer on design standards. James would welcome guidelines for all buildings so that he
has set of standards to go by.
3 combustion boilers‐ 98% efficiency
Proactive w/improvements‐ difficult to track efficiencies. Temperatures different year to year. How do I
account for efficiencies?
Software that normalizes for weather. Trend over the last 75 years its gotten warmer and warmer.
Monitoring library still and working w/ engineer. Warranty items which need to be addressed. No
baseline starting from scratch.
Professional Building
1950 iron man boiler‐ replaced w/two boiler at 50%‐ not happy w/engineer could have been smaller.
Hot water system which has been upgraded.
Air distribution modifications would improve comfort levels. Changed around 2000. Usage is different in
that building‐ business hours skew data.
Senior Center
1980 building. 3 different systems b/c done cheaply. Want to improve efficiencies. Heating and cooling
side. Want to put A/C. $87K to put A/C . Built w/CBG bond. City owns building and commissions hires
director who is responsible for day to day operations.
City Hall
1964 equipment. Steam boiler for fire station and city hall. If sell, need to replace steam boiler w/hot
water boiler possibly.
Old Library
LEED‐EB certification calls for complete change out of mechanical systems.
Was latest technology in the 80’s. Going to improve on what’s there.
Shops
60’s building. Improvements‐ 3 hile energy marshall boilers. All other buildings have smaller ceiling
mounted gas fired heating units. Could increase training/ w foreman to keep doors closed.
Tried to improve on what we have. Aggressive on maintenance, spring and fall. Keep all distribution line
Electrical side‐ work closely w/NWE and gone back to the E+ program. Changedout all the T12‐T8. New
library all T5. Office and common areas have sensors and lights. Looked at motor replacement for most
efficient motors. Filter, belts change out regularly.
Are putting in motion sensors difficult? Why not everywhere? Cost? Labor?
• Demands on me.
• Mostly contracted out
Water Use
Waterless urinals and automatic flush valves new library.
If replacing will go to more efficient. Changing out all toilets in city.
Most facilities are on underground wells so keeps us off of city water for irrigation. Watching cycles on
clocks.
Any pie in the sky that you wish we could do?
• PV’s for new city hall
• Battery back‐up for essential services facilities
• EB requirements‐ having policy’s and programs in place can give you points
• Now at mercy at private sector‐ only way to get service we want is to hire our own people
• Products‐ low VOC’s to get in projects
• Recycling carpet
• A/C unit 60 ton chiller – adding 3,000 ft to city hall. Nee to replace to get away from cfc’s
Analysis
$66K to take old windows out facing south & west will decrease heat load in old city hall.
Feels that money spent on Control specs John Phillips w/FICO who was overseeing control systems.
What you would like to see as recommended practices?
Has had good support for projects from city.
Northwestern has helped pay half for any of the projects.
• Helped w/switching out all lighting
Need to promote and track those costs better document achievements
Looking at energy star ratings
Need help monitoring and evaluating.
Energy charge and demand charge. Some based on peak demand.
Elevator motors‐ getting the motor controller changed out to lower peak demand.
Procurement practices. Hard to get buy‐in from tax payers. Consider life‐cycle, env benefits, and
economic benefits. Include life‐cycle costs in all new bid projects.
Building dpt has adopted international building codes.
Does not oversee school district.
Facilities condition index‐ national program. Mostly for universities.
• Through analysis for each of the buildings which helps use to identify long‐term usage.
• Budget‐ want to include
• Put together plans for each building‐ improvements, cost
• MSU‐ goes through every 3 years
• Puts in on objective ranking
There isn’t a system in place, need to institutionalize these practices.
Waterless urinals
How often do fluids need to be changed. Switching out 1.1 gallon.
Haven’t done a head count of all toilets.
How much foresight do people who have check have here?
• To date going for shortest payback
• Old library and window replacement is high cost
• A/C replacement‐ trane 60 ton unit ability to unload to 30 ton. If we change that out to a chilled
water system it is a more efficient system. Will cost additional $20K.
Library mechanical system can see usage at desk. Remodel will get updated system. But for Professional
building can’t .
Any low hanging fruit for old city hall. When re‐roofed office area for FS1 increased insulation. Will look
at more energy efficient options for building.
Identify needs to then put into CIP projects. It has been formalized for many municipalities. Performance
contracting.
How does lawn factor in for maintenance at library? If it’s green and grows should we send it over to the
parks?
Has energy consumption gone up? We’ve been able to maintain or decrease usage to account for
increase in terms of price.
Janitorial Crew? Day cleaning? Increase energy savings by 8%.
Yellowstone Business Partnership has normalizing data.
Having someone to track data.
Didn’t address the building envelope issues. Weather stripping?
Calculations done‐ electricity worse than natural gas
1 ton CO2e= 6.3mmbtu of electricity and 17mmbtu of natural gas
Consider Potential to effectively create some change.
How can we give James the tools to identify savings?
1. Measuring and documenting all data is first
2. Recommend what you have to do‐ hit certain efficiency standards
Do you self meter certain products. Always a moving target. Need to supply PSC with this data.
How do you come up with a savings figure? Every change you make affects something else. Changing
out light figures decreases heat load but may increasing heating for winter.
Possible Recommendations
• Day Cleaning
• Hire someone to monitor energy usage
• Set bar for standards ex: 2% per year?
• Create maintenance manual or policy guidebook
Gary Griffith with the school system has a lot of experience. Done a lot of research on monitoring.
