PARTNERSHIPS IN SUSTAINABIL ITY & ENERGY EFF IC IENCY
Presenters: Jim Ibister, Sara Terrell, Christina Reeves Date: January 28, 2016

Energy: Part of a bigger plan – Includes recycling, water efficiency, purchasing, certifications – Not just energy efficiency, but also carbon footprint reduction
Strategic process makes it more effective – Efficiency first
• Equipment retrofits • Improved operational processes
– Renewable energy for further CO2 reduction • Windsource®
• On-site renewable energy & carbon offsets
Today’s Key Takeaway: Efficiency doesn’t have to be complicated!
SPRC-XEC: OUR ENERGY STORY
LIGHTING RETROFITS FOR IMPROVED EFFICIENCY
4
Xcel Energy can help with lighting efficiency – Two types of programs
Custom Rebates – Apply BEFORE you buy – Requires information on existing & proposed product
• Quantity, wattages, lamp/fixture model # and price, annual hours of operation, etc.
– Rebates based on demand reduction (kW saved) • Up to $400/kW
Prescriptive Rebates – Submit AFTER purchase/install – Energy efficiency opportunities for both interior and exterior applications
• More straightforward, fixed rebate per type of fixture/lamp • LED rebates defer to Energy Star or DesignLights Consortium Qualified Product
Lists (DLC QPL) as a guideline
LIGHTING RETROFITS
5
Steps in our process 1. Identify the upgrade location (how many lights, what kind of fixture)
2. Talk to vendors about options
• Hang samples - get feedback – compare pricing & product performance
3. Collect info for rebate application (custom rebates)
• Total fixture quantities, product specs & pricing
• Lighting layout from supplier
4. Order fixture after rebate approval
5. Install fixtures, submit for rebate after completion

One of our first Custom Rebate projects – Figuring out our process along the way
High ceiling, long distance to throw – 400w metal halide fixture Replaced with 83w LED
Results
– Much brighter, better light quality
– Incorporated daylight sensing • Lower output & energy use on sunny days
– Over $9,500 in rebates
– Energy savings: $10,000/yr

Installed in 2015 – largest lighting project to date – Biggest event space in SPRC – 371 fixtures - replacing 250w and 400w MH
Began searching in 2011 – Products initially too expensive or not enough output – Building electricians kept looking
• Finally found something simple, relatively affordable • Samples had great light output (1.5x current lights)
Project Completion – Pre-approved for over $61,000 total rebate – >$30,000/yr energy savings – Financed by SPPA’s Trillion BTU
• No out-of-pocket cost - Paid back through savings

Working with NHL as they finalize specs for LED – Hockey requires very bright light (>200fc) – Also needs: consistency, low glare
From 100+ft up in the rafters
Working with Xcel Energy to quantify current usage
– Widely varied schedule makes it hard to estimate hours Anticipated completion: Summer 2016
– Seek to replace work lights and show lights as well – Almost 400 fixtures, currently using >750,000 kWh/yr – LEDs would cut usage in half, if not 1/3
• Savings potential: $50,000-$70,000/yr

BEYOND L IGHTING RETROFITS:
RECOMMISSIONING FOR IMPROVED EFF IC IENCY
13
What is recommissioning? (RCx) – Helps to identify existing functional systems that can be “tuned up” to run as
efficiently as possible through low- or no-cost improvements – Two steps: diagnosis & implementation
How Xcel Energy can help
– Funding up to 75% of study cost (not to exceed $25,000) – Additional rebates available for implementing identified opportunities
Other Benefits
– Save as much as 15% on energy bills – Increase equipment life & reduce wear and tear – Earn valuable credits for environmental programs & increase your
ENERGY STAR® score
RECOMMISSIONING IN A NUTSHELL
14
The Study – Almost half funded by rebates – Partner Sam Stewart & Assoc. surveyed the entire complex
• Checking equipment calibrations, leak-testing, evaluating efficiency of existing HVAC equipment & lighting
– Result: 60 recommendations for repair / improvement • Most low-cost or no-cost tweaks with very quick paybacks
The Follow-Through – Plan and timeline to implement based on cost & payback
• >30 projects have been completed
– Resulting energy savings: ~$100,000/year – Over $25,000 in further rebates for implementation

Project examples – Repairing air leaks in hard-to-reach ductwork
– Revising building-control strategies to:
• Improve space pressure, reduce equipment run-times & fan-speed settings
– Replacing CO2 sensors that were no longer calibrated properly
– Installing demand-based ventilation for kitchen equipment exhaust
In short – We tackled many simple issues and a few big improvements not easily addressed as part of daily operations & maintenance

BEYOND EFFICIENCY:
RENEWABLE ENERGY & CARBON REDUCTION
17
Xcel Energy’s Volunteer Renewable Energy Program – Allows businesses and events to buy blocks of wind energy that offset their
electric use • Sold in blocks of 100kWh with the option to chose 100% renewable energy
• Small premium (average 2015 less than a penny per kWh)
• 3-year commitment
– A Windsource ® subscription helps your business: • Meet environmental goals
• Earn LEED certification points
• Create a positive environmental impact
– Green-e Certified
– Available to residential customers as well
WHAT IS WINDSOURCE®?
18
RiverCentre & Xcel Energy Center helped pioneer this program – Short-term wind energy purchases for events ranging from one day to an
entire season
– Past participants: Minnesota Rollergirls, 2011 NHL Draft, We Day, Starkey Hearing Foundation Gala, Minnesota Government IT Symposium - and today’s Energy Efficiency Expo!
– A long-term Windsource® contract covers all MN Wild home games plus several other events
– Now a Top-5 purchaser of Windsource® in MN for three years running
Windsource® is one of several energy strategies that have together reduced our carbon footprint by over 62% since 2008.
