By offering the option of geoexchange, Earth Energy Systems, Inc. gives
builders and developers a new energy efficient, environmentally friendly, less
expensive to operate option for their client's heating and cooling needs.
Geoexchange Fact Sheet for Builders and Developers*
- Sales of geoexchange systems over the past five years have grown an average of over 22 percent per year, with a 33% increase in 1999 (the latest
year with data available).
- Geoexchange systems have a lower life-cycle cost than conventional systems, even in hot and humid regions where the demand for air-conditioning
- Energy costs with geoexchange typically are 25 to 50 percent less than
other HVAC systems.
- Surveys by utilities indicate a higher level of consumer satisfaction for
geoexchange heat pumps than for conventional systems. Polls show that
more than 95% of all geoexchange customers would recommend geoexchange
to a family member or friend.
- Geoexchange offers design flexibility because the landscape is free of noisy
condensers and other outdoor equipment.
- The elimination of outdoor equipment means the geoexchange system is not exposed to temperature extremes, dirt, pollution or vandalism.
- Geoexchange systems do not require a flue or chimney. There is less risk of
fire, and no chance at all of carbon monoxide spilling back into the building
from the heating system, because there is no on-site combustion.
- Geoexchange can reduce energy consumption--and corresponding
emissions--by over 40% compared to air source heat pumps, and by over
70% compared to electric resistance heating, according to the EPA.
Combining geoexchange with other energy-efficient measures, such as
window or insulation upgrades, generates additional savings
- Installing just 400,000 geoexchange systems each year could reduce US
greenhouse gas emissions by over 1 million metric tons of carbon each year.
This reduction in carbon emissions is equivalent to converting over half a
million cars to zero-emission vehicles, or planting over a million acres of trees.
Big Market, Bright Future*
Geoexchange has been building its share of the HVAC market for 20 years,
gaining support in both the public and private sectors.
Today, it captures
about one percent of the United States' $64 billion HVAC market.
analysts expect that figure to grow to nearly seven percent early in the next
century, carried on the demand for efficient, earth-friendly 'space
In the residential HVAC equipment market, there are two major sectors: new
construction and residential retrofit. Currently, 66 percent of the activity is in
the retrofit area, which includes energy upgrades, replacements, add-ons and
In new home construction, reasonable interest rates and favorable
demographics are expected to fuel the home building industry for the
foreseeable future. The largest increase is expected to be in the 35-64 age
range-baby boomers who have higher income and higher standards of living.
Current data supports a scenario of continued growth across all market
sectors. Over the past five years, unit sales nationally have climbed at an average of
over 22 percent per year. The 22 percent growth rate represents an increase
of over 10,000 units annually.
"People are recognizing the advantages," said Conn Abnee, executive director
of the Geothermal Heat Pump Consortium, Washington, DC. "And the impact
of that fact is being felt throughout the HVAC industry." An estimated seven
million units are expected to be installed by the year 2010.
Geoexchange technology is currently being used throughout the United
States and in several countries. Here's why:
- Geoexchange has a 25-year life cycle (50+ years for the ground loop piping)
and is virtually maintenance free.
- Geoexchange systems have a lower life-cycle cost than conventional
systems, even in hot and humid regions where the demand for air-cooling is
- Energy costs are 25 to 50 percent less than other conventional HVAC
systems, depending on latitude.
- Geoexchange is a 'green' technology in that it reduces greenhouse emissions
by 45 percent over other systems.
