The Generations of Energy: Efficiency Model
 demonstrates a 9-Point Winterization Protocol
that can be done on a house for ~$180.


logos of sponsors who made the project possible: Keweenaw Community Foundation, CLK public schools, and Michigan Tech ETEC EnterpriseThis demo is set up at our home office in downtown Hancock.  Please feel free to arrange a visit (email: through this great little exhibit that demonstrates simple things like how to open a can of caulk and use a caulk gun, to more complex solutions, like how to do a rim joist seal.

After more expensive solutions like replacing windows, and insulating the attic and walls, the rim joist is the next leakiest place in a house to address. It is something the average person is capable of but doesn’t know how to approach.  

This exhibit was built by the CLK High School Wood Shop class, and the project was chosen for funding by area high school students who make up the the Youth Advisory Council of the Keweenaw Community Foundation.

Perform a Rim Joist Seal:

See how a basement is constructed!

  • This component identifies where a basement wall meets the rim and floor joists and first-level flooring.
  • Learn how to safely cut Rigid Foam Insulation (blue board) to fit in the cavities formed by the rim joist, floor joists and floor.
  • Learn how to safely operate a spray foam gun and “glue” the blue board to the rim joist, while sealing the edges.
  • Learn to properly maintain a spray foam gun.

Caulk Windows, Doors and Floor Trim:
This model displays the inner and outer construction of windows, doors, and floor trim:

  • Learn how to correctly open a can of caulk and use a caulk gun.
  • See where the casing meets the trim on the door and window, and where the trim connects to the walls and floor.
  • Identify the places where cold air infiltrates.
  • Learn how to apply the caulk in the most effective manner.

Insulate a Water Heater:
This exhibit demonstrates the products and tools needed to:

  • Safely open a water jacket (gloves, goggles, hat, old clothes)
  • Fit the water jacket around the water heater.
  • Cut the jacket to the correct size.
  • Score the holes needed for the temperature/pressure control valve, overflow pipe and gas burner control.

Insulate Hot Water Pipes:
This exhibit is a copper pipe construction using pipes of different diameters.MTUs Construction Engineering Class pose inside Generations of Energy: Efficiency Exhibit

  • Learn how to measure the inner diameter of a pipe to determine the size of insulation required.
  • Correctly place and install pipe-wrap insulation.
  • See thermal images taken before and after showing a 10º difference.

Install a Door Sweep and Weather Stripping:

  • Learn the different types of door sweeps and the tools needed to install them.
  • Learn the different types of door weather stripping and which to use on what types of doors along with installation methods.

Insulate Outer Wall Outlets and Light Switches:
This exhibit is a bank of light switches and outlets that can be disassembled.

  • Introduction to outlet and light switch gasketing.
  • Learn about thermal bridging and how to stop it with a gasket.
  • See thermal images taken before and after showing a 7º difference.

Caulk/Foam Wire Inlets and Basement Leaks:
This exhibit is a wall showing the different types of intrusions that occur in attics and typical types of leaks in a basement foundation.

  • Learn how to correctly open a can of caulk and use a caulk gun.
  • Learn how to safely operate a spray foam gun.
  • Learn how to maintain spray foam and caulk guns.
  • Learn how to identify leaks around these areas and which product to use in addressing them.

Wire Brush Refrigerator Fins/Coils:students posing in front of old drafting table
This exhibit is a mock-up of a refrigerator with refrigerator fins.

  • Learn which product is used to clean refrigerator fins
  • See how to properly clean and maintain them, and how often.
  • Discover up to 6% energy savings.

Shop-Vac Dryer Vent Hose:
This exhibit will show where a dryer hose meets both a dryer and the outer wall of a house.
A dryer with a blocked vent can cost upwards of $3 per load compared to $.75.

  • Learn the steps required to remove the dryer vent hose from a gas or electric dryer.
  • Learn to remove the dryer vent from the outside of the house.
  • Use the shop-vac to pull the lint from the dryer hose.
  • Learn to properly reconnect the vent hose to the dryer, and the vent to the outside of the house.
