Home Energy Improvements
In
addition to being the place where you live and care for your family,
your home is the single largest investment you are likely to own. It is
important, therefore, that you know as much about it as possible. When
you bought your home you, or your Real Estate agent, probably hired an
inspector to verify that there were no problems hidden in the walls or
attic. Your house is structurally sound, and doing the job for which
you bought it, protecting you and your family.
However, how
energy efficient is your home? This question is rarely asked, yet with
ever-increasing fuel prices, it’s becoming essential. Few home
inspectors are trained in energy efficiency, and it’s a newly-emerging
issue for Real Estate agents as well. And, more and more lenders are
considering “green” mortgages, favorable rates for energy-efficient
homes.
Building Envelope
How tight is your
house? Does it hold in the heat you’ve paid for? Or do air leaks allow
cold air to infiltrate and heated air to escape? If it’s a new home,
you may have the opposite problem: it may be sealed too tightly. Fresh
air in a home is essential. If a house is too tight, odors from
cooking, smoking, breathing, and out-gassing from rugs and furniture
can seriously affect your health and that of your family.
A blower door test
can show that your house allows for the recommended number of air
changes per hour, without letting valuable heat escape. If the house
is too leaky an experienced inspector can find the leaks and make
recommendations to repair them. Your home will be snugger, and you’ll
find the heater coming on less often. The result is peace of mind, and
lower energy bills.
Duct Leakage
Forced air heating is an efficient, highly
cost-effective way to heat homes, and the one most often used in new
construction. However, studies by the California Energy Commission have
found that on average about 30% of heated air escapes from ducts into
unheated spaces such as the attic or the crawl space under the house.
(In older homes, it’s often higher than 30%!). Not only is this heat
lost to the outside, but the heating system must draw in cold, outside
air to replace the air lost. Even worse, some of that air drawn into
your home may come from a musty, damp crawlspace, or a carbon-monoxide
laden garage. Or from an attic full of insulation dust. Result: even
more fuel used, even higher heating bills, and a potential health
hazard for you and your family. Having your heating ducts tested and
sealed may be the best thing you can do to save energy, money, and your
health.
Insulation Inspection
Turning your thermostat down is a
sure way of saving energy. However, if the insulation in your home is
too thin, or badly installed, it will take too much energy to keep your
home warm at any temperature. While determining the quality of the
insulation in the walls of a finished home requires special equipment,
most attics are easily accessible. A quick visual inspection can show areas where a small investment in time and materials can pay off
in energy savings for decades to come.
