Transcript Fond du Lac Band of Lake Superior Chippewa

Fond du Lac Band of Lake
Superior Chippewa
The Minnesota Pollution Control Agency
coordinates an Americorps program,
Minnesota GreenCorps, which aims to
preserve and protect the environment
state wide while training a new generation
of environmental professionals.
Minnesota GreenCorps and
Fond du Lac

Fond du Lac’s Air Program was looking
for someone to tackle building energy
efficiency.

Fond du Lac receives the Minnesota
Pollution Control Agency news letter
where the grant for a MN GreenCorps
member was advertised.
The State of Minnesota B3 Energy Benchmarking
Program has been developed by the State of
Minnesota Department of Administration and
Department of Commerce to help state and local
governments improve the energy performance of
their buildings by tracking and managing facility
energy consumption.
Made in collaboration with the private design firm
the Weidt Group.
Fond du Lac’s Building Portfolio

Fond du Lac Manages 26 publicly owned
buildings that equal just over one million
square feet of conditioned space.

 Energy
use burns fuels that contribute
to poor air quality as well as global
climate change.
 Energy costs money and wasting energy
means there is less money to spend on
other programs.
Climate

Minnesota has the 3rd coldest winter in the
nation and experiences extreme temperatures
2012 Cloquet Temperatures
Vulnerability to Global Climate Change
Ecologically sensitive "hotspots" - Areas projected to undergo
the greatest degree of species turnover
Why Benchmark Buildings?
 You
cannot manage what you cannot
measure.
 There
is a disconnect between those
who pay the utility bills and those
who manage the buildings.
Data Collection
Gathering 3 years of utility data for all the
buildings reservation wide proved
challenging
 The Utility will provide this information
 Collect account and meter numbers and
understand what those meters power
 Push the utility to give you the best data
possible

Entering Data in B3

Keying in data can be time consuming.

It can go a lot faster if your utility can give
you digital data (numbers you can copy
and paste).

Keep a hard copy of the data.
Maintaining Data in B3

Historic utility data going back 3 years is
great but it is vital to maintain current
data as well.

We had to determine how we were going
to collect that energy use data every
month and who was going to enter it.
Analyzing the Data

Now you know how much energy your
buildings use, GREAT! But what are you
going to do with that information?

Benchmarking is a great tool to identify
potential energy savings through both
retrofit installations and more efficient
building management.

Get Facility Managers Involved
Benchmarking is a great tool to identify
poor performing buildings and create a
plan for better managing the energy use
through the building automation software.
 Training building managers to use the
benchmarking software and incorporating
efficient building management training is a
FREE way to save money and energy used.

Identifying and Prioritizing
Retro Fit Projects
Pool Covers
The Cloquet Community Center is
housed in the Fond du Lac Tribal Center.
 It has a large swimming, a small shallow
children's pool, and a spa tub
 These pools are heated to at least 70° F

Reducing the Costs of
Operating a pool
Adding pool covers reduces the amount of
energy dollars that evaporates off the pool.
 Many nationwide case studies estimate the
energy savings from pool covers from 30 %
to 55%
 Less evaporation means less make up water
and less chemicals (also cost $) needed to
treat the pool water.
 Less evaporation and less chemicals used
means less corrosion to the surrounding
structures.

Update the HVAC System
Early Head Start Building
 Used by the preschool education
program
 18,000 SF containing classrooms, offices
and a kitchen.
 The building has electric resistance heat
in the ductwork with 2 exterior air
handlers and 2 split system air
conditioners

What Do the Numbers Mean?

Using the Benchmark tool helps you
understand how much energy you could
save if you bring the building up to the
current energy code.
Looking Beyond the Numbers

What type of energy is being used to heat
the building matters.
The Fuel Type Matters
HVAC Occupancy Sensors
Black Bear Resort and Casino hotel
rooms
 234,025 SF more than half of square feet
of the complex
 The hotel rooms use the largest portion
of energy for the complex and a great
deal of that comes from heating and
cooling
 Occupancy controls for the HVAC can
cut down on energy used.

Infrared Occupancy Sensors
Completed Projects
Lighting Retrofits
Lighting Retrofits are the low hanging fruit of
energy efficiency improvements.
 Fond du Lac has been changing out their old
lights for new more efficient one and it has paid
off in energy costs and maintenance

Large Space Air Management
System
Why ventilate a gym for 120 occupants
when you have a gym class with 30
students in the space. Moving around that
much air and conditioning outside air
uses a lot of energy.
 A large space air management system was
installed at the Ojibwe school gym which
included a variable speed drive as well as
CO occupancy sensors.

This is data from the Large Space Air
Management system in the Ojibwe School
which was completed in August of 2012.
