OUTSIDE
AIR "AC"
Free
Air Conditioning!
Saving Money!
The U.S. Department of Energy reports that...
"Optimized
ventilation
presents one of the largest
opportunities for energy and money savings...".
The
home guide, Best Ways To Save On Home
Energy Costs by Sunset Books, states...
"In
temperate weather, (moving) outside air
throught the entire house can substantially
reduce the money you spend on air conditioning."
In
the Better Homes & Gardens Complete Guide To
Home Repair & Improvement, it reports...
"Power
ventilation reduces energy costs by a
surprising amount."
According
to Federal Energy
Research...
"Heating
and cooling accounts for about half
the energy you use in your home. Since the
heating and cooling systems usually last 10
years or more, the choices you make will
affect your utility bills - and your wallet - for
years to come."
A Florida Power & Light Report states that...
"Natural
ventilation can reduce or even
eliminate air conditioning costs
by providing much of the cooling
needed to make a home comfortable.
Ventilate when the outside temperature
is below 77 degrees and at night..."
A
Report in Alternative Cooling & Low Energy Systems states...
"It
is a paradox that in buildings throughout
the world, even in temperate climates, that
vapour compression equipment (air conditioning)
is providing cooling throughout the year even
though the external temperature for the vast
majority of time is lower that the internal building
ambient temperature."
At
a "Cooling Frontiers Symposium", UCLA researchers
La Roche and Milne reported...
"...the
greatest single source of free cooling energy
for homeowners is outdoor air. Most homes are not
designed to effectively 'harvest' this resource, and
most homeowners do not understand how to manage
or control it. Proof of this is the common situation where
home air conditioner is running when the outside air
is quite comfortable."
Here's how it works...
From
October through May - two-thirds of the year - we
get to enjoy our great Florida weather. When the outside
air is refreshing and comfortable, the Natural Air System
will automatically use that fresh air source to cool or
heat your home to the exact comfort level you want...
instead of powering up and wearing out your expensive
to run, repair, and replace central air conditioning system.

Outdoor
air temperatures are favorable on
average, for "FREE AC" outside air intake
at least for parts of days during entire year.
For example, even in cold February and hot
August, outside temperatures during periods
of the day are a moderate 74 degrees, when
fresh air can be brought in by the Natural Air
System to maintain desired comfort.
Red Temperature Areas Usually Require The
Natural Air System Automatic Humidity Control
System To Be Activated When Pulling In Fresh
Air -- Providing Somewhat Lower Savings.

THE
NATURAL AIR SYSTEM automatically Uses Favorable
Outdoor Air To Heat Or Cool When Possible... And When
Taking In The Prescribed Amounts Of Outside Fresh Air
Into The Home... Will Do So At The Most Favorable Time Of
The Day For The Most Favorable Outside Air Conditions.
Indoor Humidity Is Automatically Controlled.
Another example of significant money savings was reported in the Lakeland (Fl) Ledger on May 17, 2003, where the results of an energy-saving test home was reported. It was stated that a conventional home of the same size (2,425 square feet) would use 37.5 kilowatt hours on a sunny summer day, while the energy-saving test home was only using 5.8 kilowatt hours, with daily energy costs dropping from $2.81 to 43 cents per day. Over 30 days of such operation, these cash savings would mount up to over $700 for the homeowners that are able to use less air conditioning.
Poor Attic Ventilation Also Costs Money!
THE
NATURAL AIR SYSTEM
ALSO VENTILATES THE ATTIC TO SAVE EVEN
MORE MONEY... BY PUMPING THE STALE BUT
CONDITIONED INSIDE AIR INTO THE ATTIC...
FLUSHING IT OUT AT THE SAME TIME.
Attic air heat can reach 150 degrees...
A Natural Air indoor cycle also flushes out hot attic air and moisture!
The
excessive hot or cold air that builds up in your attic causes your
central air unit to work harder and longer to maintain your desired
temperatures inside your living area, in some cases using over 50%
of the output and costs of operating the central air conditioning unit.
Attic
heat flows into the living areas below, often all night long, causing
your cooling unit to continue working many hours to remove that extra
heat load. The hot attic air also transfers heat into the air conditioning
components - such as air distribution ducts - causing them to loose
cooling capacity and to run for longer periods.
The U.S. Department of Energy has found that a conventional central
air conditioning unit with attic components can loose one-third of capacity...
where a three-ton unit for instance, puts out only around
two-tons to actually cool the home interior... but you pay for it
all.
Inadequate
attic air flow also causes advanced deterioration of the roofing
structure, insulation, vapor barriers, and air conditioning equipment...
mainly from the excessive temperature and humidity levels that build
up in attics... often requiring costly repairs or replacements. Many
roofing material suppliers will not guarantee their materials on unvented
attics. AP writer David Bradley stated in a research article on roofing
that...
"...poor
ventilation beneath the roof is the major
culprit in roof deterioration. Heat and trapped
moisture are largely to blame."
Normally,
it is not easy to achieve good attic ventilation, especially so
when attempting to moderate the wide ranges of differences between
attic temperatures and humidity levels, and that in the living areas
inside the home. The higher the difference between inside air temperature
and humidity, and the attic heat and humidity, the more transfer there
is of heat and humidity from the attic air down into the interior air...
which obviously requires more run time on the air conditioning system
to handle the added loads.

Actual
energy & money savings will vary according to such
variables as type and construction of home, the number of people, lifestyles,
weather conditions, and personal preferences as to inside
air conditions and the amounts of fresh air brought into the home by
the automated computer control settings of the Natural Air System.
According to research, on average a central AC in this area runs around 2,500 hours a year with energy costs as high as $1.50 per hour. This is why central air is easily your highest expense item.
However, you also need to factor in the fact that improvements such
as the Natural Air System usually recoup their price via a higher sale
price
when the dwelling is sold. Additionally, if you run your AC half as
much, it should last somewhere around twice as long while requiring
fewer repairs. That means the significant money spent to repair and
replace the AC stays in your pocket!
When
you add both $ return factors together - not counting improved
health benefits and other payoffs - the Natural Air System should
"return" much more than it cost, be a good investment value
for you.
