We
were once able to achieve natural ventilation in our homes
by merely opening a window. However, with the concern for
energy efficiency in recent years, we have been busy making
homes “tighter” from an energy standpoint. Armed
with weather-stripping and caulk guns, we have eliminated
air leaks from our homes. Unfortunately, that has also eliminated
the opportunity for outside ventilation that could help
to reduce concentrations of indoor contaminants. But, thanks
to some innovative engineering, it isn’t necessary
to throw energy efficiency out the window in order to grab
a breath of fresh air.
HOW
CAN I VENTILATE MY HOME AND STILL BE ENERGY EFFICIENT?
It
is now possible to exchange stale indoor air with fresh
outdoor air without compromising the energy efficiency of
your home. With heat recovery ventilators (HRV’s)
and energy recovery ventilators (ERV’s), it’s
out with the bad air and in with the good — all without
wasting energy. HRV’s and ERV’s are electronically
powered units that circulate air throughout your home, using
the existing forced air system or specially installed ducts.
The units pump stale air out of your home and replace it
with an equal volume of fresh outside air. The HRV is a
compact unit that conditions the temperature of the outside
air, while the ERV is a packaged unit that conditions both
the temperature and humidity of the outside air. Because
these units condition the air before it enters the home,
your energy costs remain stable.
PROVIDING FRESH AIR FOR EXCHANGE
The HRV uses virtually noise-free fans that draw in fresh,
cool outdoor air while it removes stale, heated indoor air.
The ERV performs the same function, only utilizing a rotary
energy recovery wheel. In both cases, the units transfer
the temperature and moisture properties from one air stream
to the other, without allowing the two airflows to mix.
Both units offer easy access for change of filters and necessary
maintenance, making them not only energy efficient, but
easy to use.
DETERMINING
IF AN HRV OR ERV IS RIGHT FOR YOU
If you’re wondering whether you need to clear the
air in your home, you might ask yourself these questions:
1.
When was your home built? If your home is new,
chances are it has been built “tighter” to be
more energy efficient. This may mean concentrations of air
pollutants in your home could be a concern.
2.
Have you upgraded your home to be more energy efficient?
If so, it may need an additional source of ventilation.
3.
How often during the year can you comfortably open your
windows? Due to cold winters and hot summers, it
is not always possible to have your windows open year-round.
This means that you may not always have a constant controlled
source of ventilation.
4.
Do odors tend to linger in your home? If this is
the case, it is a sign of poor ventilation. There isn’t
enough air being circulated throughout the home to dilute
unwanted odors.
QUALITY
YOU CAN COUNT ON
Your home comfort should include products and accessories
that improve indoor air quality. Your family’s health
and comfort should be a priority, and working together,
we can help you provide your family with a “breath
of fresh air”. The benefits you’ll feel and
see will be worth it.
