1. Center for Energy and Environment
Minnesota History Center:
Six Years (and counting) of
Energy Conservation Work

2. The results have been dramatic
 Total energy used by the Minnesota
History Center has been cut in half in
6 years without affecting operations or
personal comfort.
Year % Savings
2007 6%
2008 0%
2009 9%
2010 11%
2011 26%
2012 12% -6% -6% -9% -20% -46% -58%

4. How was it done?
 HVAC and Controls Upgrade in 2008-9 – 20%
 Implementation of best practices by staff with Plant
Management. Ongoing – 26%
 Recommissioning with Public Buildings Enhanced
Energy Efficiency Program. 2012 – 10%
 Upgrade lighting, including LED’s. 2013 – 5-10%

5. Typical measuring: Scheduling
 Use equipment when you need it (and the amount
you need)
3,000
Page 5

6. Typical Measure: Special Use Spaces
 Classrooms hold up to 60 people and can be used in the
evenings
 Install a special button to activate ventilation when used
after hours
 Vary amount of ventilation based on number of people
Page 6

7. Typical Measure: Low Flow Faucets
 24 Public Lavatories, assume hot water is used 5
minutes/hour, saves over 200,000 gallons of hot
water and $1,200 a year. You can do this at home,
too.

8. Overall Energy Conservation Savings are
over 20% at the Capitol Complex
-8% -10% -19% -25%
 Using Best Practices continuously across the Capitol
Complex has met the Governor’s Goal of 20% Energy
Savings compared to the baseline year.

9. The Future of Energy Includes Efficiency
 SB2030 standards will get us to Net Zero buildings
 Renewable Energy
 Integrated Design
 Efficiency
 142,000 square feet
 4,316 photovoltaic panels
 1 MW or
 1.2 Million kWh annually
 14% of MHS Usage
