Why Choose Energy Star Housing?

High Energy Bills

Air leaks in your home’s envelope

Inefficient windows Inefficient heating

or cooling equipment

Poorly sealed and insulated ducts

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

Did you know that a typical home can cause twice the greenhouse gas emissions of the typical car?

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

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?

Each Energy Star qualified home can keep 4,500 lbs of green house gases out of our air each year

Energy Wise Building Methods

ICFAn Overview ofInsulated Concrete Forms

For thousands of years, concrete has been a common component...

...offering structural integrity to building envelopes.

Use of Expanded Polystyrene

Since the early 1960’s, expanded polystyrene (EPS) has been used for its exceptional insulating qualities

Today, ICF’s innovative form technology has successfully married concrete and EPS to give a new alternative to concrete wall construction…

And utilizing simple, common sense construction techniques…

…high performance wall systems

Geothermal Heating and Cooling

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

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

System Operating Cost Comparison

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

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.

What Is a Geothermal Heat Pump?

LPK

TO LOOP

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)

Geothermal Loops

Closed Loops▫ Horizontal▫ Vertical▫ pond/lake

Open Loops▫ Well water

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

Applications

Forced air heating and cooling Supplemental water heating Dedicated water heating (radiant floor,

snow melt, pools) Add-on splits to fossil fuel furnaces

Geothermal System Benefits

Energy savings up to 60% Quiet operation No short, hot blasts of air - more even heat No noisy outdoor unit Less maintenance Long equipment life No flame, fumes or combustion - SAFE No unsightly outdoor tanks (propane) Environmentally friendly Clean

Customer Satisfaction

According to the International Ground Source Heat Pump Association (IGSHPA) 99% of geothermal system owners are so satisfied with their systems they would recommend one to a friend

US Environmental Impact

Nearly 1,295,000 cars taken off the road

More than 385 million trees planted

Reduce reliance on imported fuels by 21.5 million barrels of crude oil per year

Federal Tax Incentives (2009 – 2010)

New and Replacement HVAC Systems▫ 30% tax credit to homeowner▫ Geothermal equipment must be Energy Star

rated

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

Local Property Tax Incentives

home change-out Ranges from $50-350/year

The #1 reason that homeowners decide to install a geothermal system in their home…

Energy Savings▫ Once they own the system, they love it for

its comfort, quietness and reliability!
