The
Young Home
2008 GRAND Aurora Award Winner
&
2009 APEX Winner for Energy Efficiency!
For 12 months, this 6640 square foot home buys about 73 KWH
per day (2209 KWH per month) with approximately 35 KWH of it
being for home comfort (heat/air) and hot water. How much is
that in dollars? At $0.11 a KWH, the average monthly utility
bill is $243 a month. And that includes their heated pool
and lawn pumps! According to a 2005 study by AEC, a 1500 sq
ft all electric home (without pool and lawn pumps) averaged
1910 KWH. This is about 4.5 times larger than that with only
16% higher power bill! Turn off the pool pump and lawn pumps
and it would drop below the average 1500 sq ft home! What
drives all of this? Super tight construction utilizing
WaterFurnace Geothermal heating/cooling, Spray Foam
Insulation, and solar power.
 
Air Conditioning & Heating:
The concept was building a home around the latest and
greatest in energy conservation. In 2007, Dept. of Energy
states that 55% of our bill goes for heating, cooling, and
hot water. According to the EPA, geothermal systems are the
most energy efficient, environmentally clean, and
cost-effective space conditioning systems available (source:
"Space Conditioning: The Next Frontier," EPA 430-R-93-004,
April 1993).
To get the lowest possible power bills at the highest level
of indoor comfort , we selected the home comfort system to
use three WaterFurnace NDV Series systems using a four ton
for the main living, two ton for the master suite, and two
ton for the guest area. These systems all use two stage
compressors and twelve speed, variable blowers, touch screen
programmable thermostats, and latest environmentally
friendly 410 refrigerant. As with most geothermal systems,
no outside unit is necessary.
Because of the two stage compressor, the four ton, the EER
is 22.7-29.6 depending on what stage the compressor is
running. The two ton units has an EER of 26-34.5. An
equivalent SEER would range from about 31 to 46.
  
Insulation:
Applied as a liquid, spray foam expands to 100 times its
volume to fill every crack and crevice while remaining
flexible so that the integrity of the building envelope seal
remains intact over time. It acts as a complete insulation
and air barrier to minimize air leakage and seal the
building envelope for optimal airtightness. According to the
Minneapolis Blower Door testing, the estimated cost of air
leakage for heating/cooling in this home is about $10 a
month.
 
  
Solar Panels
Solar panels were also installed to deliver roughly 30KW per
day with this home needing roughly 102KW a day. Bulk of the
domestic water heating is done with solar panels with hot
water assist off the geothermal heating/cooling system. The
solar panels also provide 100% of the water needed to heat
the swimming pool. Additional solar power that is generated
is sold back to the utility company.

End Result:
A very efficient home that gained roughly 1600 square foot
of usable semi conditioned attic space, all the hot water
you’ll ever need, extremely comfortable and even temperature
rooms, and at a power bill any homestead could afford. The
home is super quiet and extremely energy efficient, based on
the savings in power bill versus increased mortgage, the
higher standard of efficiency actually saves money every
month!
