Why Choose Energy Star Housing?
![Page 14: Shelterwood Homes](https://reader037.vdocuments.us/reader037/viewer/2022110306/554e1362b4c90518298b56d2/html5/thumbnails/14.jpg)
High Energy Bills
Air leaks in your home’s envelope
Inefficient windows Inefficient heating
or cooling equipment
Poorly sealed and insulated ducts
![Page 15: Shelterwood Homes](https://reader037.vdocuments.us/reader037/viewer/2022110306/554e1362b4c90518298b56d2/html5/thumbnails/15.jpg)
Drafty Rooms
Caused by cold air coming into or going out of your house
Leaks hidden in the attic and basement

Hot or Cold Rooms
Significant differences in room temperature could be caused by several factors▫ Inadequate insulations▫ Air leakage▫ Poor duct performance
![Page 17: Shelterwood Homes](https://reader037.vdocuments.us/reader037/viewer/2022110306/554e1362b4c90518298b56d2/html5/thumbnails/17.jpg)
Did you know that a typical home can cause twice the greenhouse gas emissions of the typical car?
![Page 18: Shelterwood Homes](https://reader037.vdocuments.us/reader037/viewer/2022110306/554e1362b4c90518298b56d2/html5/thumbnails/18.jpg)
Did you know?
In 2005, the Energy Star program as helped Americans have save▫ Enough energy in 2005
alone to avoid greenhouse gas emissions equivalent to those from 23 million cars
▫ $12 billion on their utility bills
![Page 19: Shelterwood Homes](https://reader037.vdocuments.us/reader037/viewer/2022110306/554e1362b4c90518298b56d2/html5/thumbnails/19.jpg)
The average family spends $1,900 a year on energy bills
Energy efficient choices▫ Save families about a
third on their energy bill
▫ Save on greenhouse gas emissions
▫ No sacrifice in features, style, or comfort
Did you know?

Geothermal Facts
In a February 2006 report, the Energy Information Administration states that between 2005 and 2010 of the renewable fuels available today for residential use including solar, wind turbines, and forms of biomass, the most widely used and readily available residential renewable energy is geothermal energy from ground source heat pumps
![Page 122: Shelterwood Homes](https://reader037.vdocuments.us/reader037/viewer/2022110306/554e1362b4c90518298b56d2/html5/thumbnails/122.jpg)
Your Energy Bill...
If you are a typical homeowner▫ About 70% of your total energy bill is for
heating, cooling and hot water▫ The rest is for lighting, appliances and other
usage Therefore, the biggest opportunity to save
large amounts of money on your energy bill is to increase the efficiency of you heating cooling, and hot water system
![Page 123: Shelterwood Homes](https://reader037.vdocuments.us/reader037/viewer/2022110306/554e1362b4c90518298b56d2/html5/thumbnails/123.jpg)

What Is Geothermal Energy?
Geothermal systems use the earth or well-water to provide heating, cooling and hot water for your home
A heat pump “moves” energy from one location to another, instead of creating heat by burning fossil fuels, such as a gas furnace does▫ Works like your refrigerator▫ Winter vs Summer
![Page 125: Shelterwood Homes](https://reader037.vdocuments.us/reader037/viewer/2022110306/554e1362b4c90518298b56d2/html5/thumbnails/125.jpg)
How can it heat using the earth temperatures?
A few feet below the surface, earth temperatures remain relatively constant and moderate.
Ground temperatures are much milder than average monthly air temperatures.
![Page 126: Shelterwood Homes](https://reader037.vdocuments.us/reader037/viewer/2022110306/554e1362b4c90518298b56d2/html5/thumbnails/126.jpg)

How Does the Heat Move from the Earth to My Home?
The heat pump moves through a liquid medium ▫ Inside a loop system (CLOSED LOOP) ▫ Through well-water (OPEN LOOP)
![Page 128: Shelterwood Homes](https://reader037.vdocuments.us/reader037/viewer/2022110306/554e1362b4c90518298b56d2/html5/thumbnails/128.jpg)
Geothermal Loops
Closed Loops▫ Horizontal▫ Vertical▫ pond/lake
Open Loops▫ Well water
![Page 129: Shelterwood Homes](https://reader037.vdocuments.us/reader037/viewer/2022110306/554e1362b4c90518298b56d2/html5/thumbnails/129.jpg)
Open Loop Systems
Key considerations▫ Adequate water supply (5-9 gpm in addition
to household requirements)▫ Good quality water (low mineral content)▫ Adequate discharge location (drainage
ditch, field tile, pond, etc.)▫ Only changes the temperature of the water
a few degrees

Closed Loops
High density polyethylene pipe (life expectancy of over 200 years)
Does not rust, rot, or corrode All connections are made by heat fusion 55 year No Leak warranty

What About Hot Water?
A geothermal unit can make hot water too! An optional component makes hot water
when the unit is heating or cooling your home
The unit will generally make around 50-75% of the hot water required for your home, but the actual amount can vary depending on run time ▫ The rest of the hot water is generated by your
conventional water heater. Free hot water during cooling
![Page 132: Shelterwood Homes](https://reader037.vdocuments.us/reader037/viewer/2022110306/554e1362b4c90518298b56d2/html5/thumbnails/132.jpg)

Federal Tax Incentives for Homebuilders(2009 – 2010)
A builder can claim a $2,000 Federal Tax Credit per home if the structure exceeds the 2004 International Energy Efficiency Code by 50%
An Energy Star home, already exceeds the 2004 IECC by at least 30%; adding a geothermal system will get the home to the 50% level in most cases
