What's In Your Attic?

Winter is on its way and, with it, so come the frigid temperatures. Do you know what’s in your attic?…or walls?…or floor? Hopefully the answer is insulation. In the United States, heating and cooling account for 50 to 70% of all energy used in the home. A lot of that energy is being wasted because of inefficient building practices. Ensuring proper insulation in your home can make you more comfortable, save money and reduce the burden our limited energy resources. Here are a few things that you should know about insulation.

How Insulation works

Heat naturally travels from warm to cold space through conduction, convection and radiation. In winter, heat moves from our living spaces to wherever it is colder, typically outdoors. This lost heat must be replaced by a heating system to maintain comfort. In the summer, heat moves from outdoors in and must then be removed by an air conditioner. Insulating decreases the heating and cooling that is needed by providing an effective resistance to the natural flow of heat. This thermal resistance is known as the R-value. The R-values vary widely depending on the type of material, its thickness and density. The higher the R-value, the more effective the insulation.

Types of Insulation

Blanket or Batt insulation is traditionally made of mineral fibers or rock wool, but are now available in cotton, sheep’s wool and hemp. They are available in a variety of widths and are available with or without vapor retardant facing. Because of its availability and ease of installation, blanket insulation is a great choice for the homeowner.

Loose Fill insulation is typically made from cellulose (recycled paper), fiberglass or rock wool. These loose fibers are blown into walls and attics using pneumatic equipment, usually by professionals. Loose fill can be packed in to existing walls and irregularly shapes areas, making it an excellent option for retrofits on older homes.

Foam insulation is sprayed in liquid form using special equipment by professionals. This insulation comes in open or closed cell varieties. Open cell foam allows water vapor to pass through, but has a lower R-value. Closed cell foam is a better choice when space is limited.

Rigid insulation is made from plastic foams and is molded into board forms. Rigid foam is often used on foundation walls.

Insulation Fun Facts
  • Insulation reduces average home heating and cooling costs by around 20%. [1]
  • Insulation currently in place in U.S. buildings reduces the amount of carbon dioxide by 780 million tons each year. [2] This is the equivalent to the electricity use of over 90 million homes for one year [3] 
  • For every Brittish Thermal Unit (Btu) consumed in the production of insulation, 12 Btus are saved each year by the use of insulation. [4]
  • All insulation products installed in U.S. buildings save consumers about 12 quadrillion Btus annually, or about 42% of the energy that would have been consumed with no insulation in place. [5]
  • This is the equivalent of 40 million Btus or 7 barrels of oil per person per year. [6] This is the equivalent of 28 barrels of oil saved by each U.S. family of four per year. 
  • Energy efficiency through insulation is the simplest and most cost effective way to reduce energy use and greenhouse gas emissions.  [7]

Senator Bennet Announces 4CORE's USDA Grant


Colorado U.S. Senator Michael Bennet today announced that the Four Corners Office for Resource Efficiency (4CORE) has won a $50,000 grant from the U.S. Department of Agriculture’s (USDA) Housing Preservation Grant program. The grant will be used for home repairs and energy efficient improvements for low-income rural residents.

“This grant will help Coloradans save money on their monthly energy bills while improving housing conditions,” Bennet said.  “4CORE’s work with local communities is another example of Colorado’s vision and leadership on energy conservation and sustainability.”

"This funding will complement our existing Weatherization Assistance Program and allow us to better assist low-income residents, many of whom work full time, but still qualify as low-income,” said Gregg Dubit, director of 4CORE. “In addition to improving energy efficiency for families, we'll be able to repair and resolve health and safety issues, such as indoor air quality, leaking furnaces, and other potentially unsafe problems.”

4CORE serves southwest Colorado by helping communities conserve energy and integrating energy efficiency and renewable energy into the daily lives of Coloradans.

The Housing Preservation Grant program provides grants to sponsoring organizations for the repair or rehabilitation of low- and very low-income housing.  The grants are competitive and are made available in areas where there is a concentration of need.

Home Spotlight Event Provides Glimpse of Net Zero

Home Features Geothermal, Solar, and other efficient qualities 

The first Home Spotlight event takes place from 4 to 7 PM on November 3rd as part of a quarterly series hosted by the Four Corners Office for Resource Efficiency (4CORE). La Plata County homeowners Richard and Jill Hoehlein will open their home to educate the public and raise awareness about the value and comfort of a sustainably built, net zero home.

The Hoehlein’s home was designed as a prototype with plans available at a discount so renewable energy and energy efficient features can be easily replicated for other homeowners. Passive solar design is used, along with natural day-lighting techniques, solar photovoltaic, and solar hot water to take full advantage of the 278 days of sunshine in our region. Home comfort and low heating costs are ensured by a geo-exchange ground source heating and cooling system, combined with quality air sealing, superior insulation, and a heat recovery ventilation system. A Growing Spaces Growing Dome® provides food year-round, with xeriscaping and native landscaping maintained around the home with drip irrigation. Finally, universal design features accommodate people with physical disabilities.

Register here for the Tour ~ It's FREE!


"We are delighted to share our experience in building the county's first LEED platinum home and our commitment to living in a way that is highly energy efficient and environmentally responsible,” said Richard Hoehlein, the homeowner. “Hopefully it will serve as a model for others who share our concern about the long-term sustainability of our planet's resources and would value living in an essentially net-zero energy residence."

The home is located at located at 602 Powder Horn Trail just outside of Durango and the event is free and open to the public. Suppliers and builders will be on-hand to explain the products and processes used to construct the home. A Road Runner Transit shuttle bus will run from the Durango Transit Center to the home between the hours of 4 and 7 PM. 

“We are pleased to showcase this relatively modest home,” said Mark Galbraith of Galbraith Builders. “The mix of geothermal, solar and energy efficient attributes makes this home the ideal solution for anyone who wants to minimize their impact while living in the utmost comfort.”

Plug Loads = Opportunities for Savings!

Our households and offices have more plug-in devices than ever before. The use of home electronics, mobile devices and computers has increased rapidly over the years.

We often think of space heating as the main energy gobbling culprit. Much less attention is given to the plethora of devices that plug into the wall sockets. Current information shows that these “plug loads” can contribute anywhere from 9 – 20% of a home’s energy usage.

For instance: A single workspace can consume 1,500 kWh each year. 
That's an average cost of $175!

Common plug loads:

  • Televisions
  • DVD players
  • Computers
  • Stereo systems
  • Printers
  • Remote controlled devices

Many of these devices, such as set-top boxes and computers, are left on even when unused. Others are “turned off" but still use a significant amount of standby-power, like televisions and stereos.

How do you identify and manage the worst abusers? What can you do to curb your plug load consumption? What tools are out there to help?

Join us for a free Brown Bag Session October 17th from noon – 1:15 pm at the First National Bank of Durango, in the downstairs training room.

Our presenter, Erica Lighthiser, from Ecova, will cover the following topics:
1.      What are plug loads?
2.      Why are they a problem?
3.      Simple steps to save energy and money at your home or office.
4.      Alternatives to the gadgets you can’t live without.

When we save electricity, we save money and decrease emissions from power plants.

Remember, the cheapest (and cleanest!) energy is the energy that is never used!
