Cause for Concern
Outdoor
air is continually being cleansed by nature using the natural processes
of weather, rain, wind, lightning, and ultraviolet energy from the sun.
Nature's methods of cleaning outdoor air are not naturally present in
our indoor air environment. Man-made synthetic building materials,
furnishings, and household cleaning products have created a virtual
chemical soup in our homes with no natural method of control.
One
of the main reasons for heightened public concern about deteriorating
indoor air quality is the alarming increase in the number of children
and young adults with severe allergies and asthma.
According
to the National Center for Health Statistics, 2001 National Health
Interview Study, over 7.6 million children (5-17 years) and over 12.7
million young adults (18-44 years) suffer from asthma. The United
States Environmental Protection Agency ranked indoor air pollution
among the top five environmental dangers to the public. EPA research
also concluded that indoor air can be two to five times (and sometimes
as much as 100 times!) more polluted than the WORST outside air! Since
research indicates Americans spend 90% of their time indoors, it's no
wonder that asthma and allergy suffering is on the rise.
Why the Increase?
Why
has indoor air quality substantially deteriorated over the last 30-40
years? Because changes in new home construction materials and practices
that evolved out of the 1970's energy crisis created “tight homes” that
are tightly sealed, heavily insulated and very energy efficient. While
these practices help to conserve energy, they also “lock in” allergenic
particles, infectious agents, and toxic compounds which are bad for the
health and well being of our families.
Allergenic
particles such as pollen, dust, mold spores, fungi spores, tobacco
smoke, dust mite feces, pet hair and pet dander all contribute to poor
indoor air quality. Additionally, common household furnishings such as
draperies, carpeting, wallpaper, paints, stains, and furniture may
continue to “off-gas” potentially toxic fumes for a long time after
application or installation. Heating and air conditioning ducts which
are dark, damp and rich in “nutrients” provide an excellent breeding
ground for mold, fungi, and dust mites which can spread rapidly when
these ducts are in use to heat or cool the home. Poor ventilation and
dirty filters are also major contributors to unhealthy contaminates in
the home.
What can be done?
There
are many products on the market today that work with your existing home
comfort system to provide unparalleled filtration and cleansing. There
are basically three categories of infectious agents that need to be
addressed by your IAQ (indoor air quality) system:
Allergens
and Particulates that can cause health effects such as nose and throat
irritation, runny nose, congestion, and asthma flares. This is
controlled by high quality filtration.
Infectious Agents that can cause bacterial and viral infections. This is controlled by a UVC light.
Toxic
Compounds that include formaldehyde, carbon monoxide, smoke, and mold
mycotoxins that can create such symptoms as memory lapse, depression,
headaches, and fatigue. This is controlled by a UVV light.
We have Comfort Advisors standing by that would be happy to visit your
home for a free IAQ analysis. They can answer any of your questions
about what would be best for you and what options on the market today
would best fit your needs. Call us today at 850-983-6688. You can also
get more information on Indoor Air Quality and browse through some
excellent products at our vendor partner Nature's Home. Visit their

Whole House as a System Approach
The
house as a system approach to heating and air conditioning in based on
building science research that was started during the energy crisis of
the 70's. Princeton University led the way and designed an
Infiltrometer blower door that can be used to measure the air tightness
of a structure. Air movement into and out of homes is called
infiltration and exfiltration. They found a direct correlation between
the uncontrolled air movement into and out of homes and energy
expenses.
This unwanted air
movement for which Energy Savers uses the acronym, DARK AIR, is a
combination of poor design and construction, antiquated plumbing
systems, and or inefficient and poorly installed air distribution
systems (ductwork) which create multiple problems. The home owner sees
these problems as mold, dirt, uneven temperatures and high energy bills
(Utility Overpayment. In general home owners are frustrated and upset
that their energy bills are high and that their home is still not
comfortable!
Because of these
problems and the need to identify them, Energy Savers approaches the
house as a system, our comfort Consultants use an Infiltrometer Blower
Door, Forward Looking Infrared imaging, Data loggers and other
diagnostic equipment to test homes and find the problems.
DARK Air
On
the other end of IAQ spectrum are far more homes that are Not tight, In
fact they leak Air like a tent, air duct systems that hemorrhage hard
earned energy dollars. Energy Savers of Florida wants to inform our
customers of the potential health hazards that exist in most homes and
older mechanical systems and ways we can help.

DARK
air is BAD air! DARK air is air leaking from your attic, garage and
crawl space into your home. Ask us how we can make your DARK air LIGHT!
