Turn
It Down !
Turn
down the furnace thermostat. You can save as much as $3-$5
per month by simply turning down the thermostat one degree,
and another $15-$25 by setting it back 5 degrees at night
or when no one is at home. Installing a set-back thermostat
will do this automatically. Remember, keeping your furnace
clean and in good repair will ensure that it runs to peak
efficiency. It is good practice to change your furnace filter
monthly during the heating season.
Turn down the water heater thermostat.
Most
people have their water heaters turned up way too high (160
degrees), 120 degrees (the low setting for gas water heaters)
is high enough to meet your hot water needs. Wrapping your
water heater and inlet and outlet pipes with additional
insulation will decrease heat loss and pay for itself in
less than one year.
Use low wattage task lighting where illumination is needed
only for a small area, such as a favorite reading chair.
Consider replacing frequently used high wattage bulbs with
compact fluorescent light that last ten times as long as
incandescent bulbs.
Install low-flow showerheads. Typically a standard showerhead
allows more water flow than is needed. Installing a low-flow
showerhead can save you close to 10 gallons during a five
minute shower.
Seal
It Up !
Caulk,
weather-strip, and foam to seal air leaks. Even though you may
have a furnace and an air conditioner that run at or above standard
efficiency, losing all that conditioned air through leaks in
your house is truly "conditioning the great outdoors".
Pay special attention to the areas around windows and doors,
where pipes enter walls, around light switch and outlet boxes
(foam gaskets work best), and anywhere two materials meet. Caulk
the interior of wall cracks, not the exterior. Use rope caulk
around very leaky windows. Weather-strip your attic access hatch
to prevent conditioned air from escaping. Seal your exposed
air ducts with mastic or metal butyl tape and wrap them with
insulation.
Close your fireplace damper when it is not in use. Don't ever
start a fire and turn up the furnace thermostat at the same
time! If you rarely or never use your fireplace, consider covering
the opening with cardboard or some other type of material to
decrease loss of conditioned air.
Repair or replace windows. When repairing windows, don't seal
cracks in the glass, replace the whole pane. Make sure your
windows shut tight and fit properly. Windows are expensive to
replace, if you are considering replacing all or a large portion
of your windows, make sure it will be a cost effective upgrade.
Fill
It In !
Make
sure walls, attics, and floors are filled with adequate insulation.
Too often existing homes have little or no insulation in the
walls and attics. Removing switch plates or outlet covers on
outside walls and paying a visit to your attic can help you
determine how much insulation you have working for you during
those cold winters and hot summers. Attic insulation should
be at an R-30 or greater level for a cold climate. The type
of insulation you have in your attic determines the thickness
and R value present. An insulation specialist can help you determine
if it is necessary to add to your attic insulation. The R value
of the insulation in your walls is harder to determine and difficult
to increase. With typical 2 x 4 construction, you should have
at least an R-11 in your walls. If your walls have no insulation
and there is space to add it, consider having insulation blown-in.
This will help to keep the conditioned air in and your energy
bills down. Make sure that it is a cost effective improvement.
If you have an unfinished basement or crawlspace, adding insulation
to the ceiling (floor joist) will work to ensure that you are
not allowing heat to travel to this area. Heat only the areas
that you want to heat and not the unconditioned parts of your
home.
Keep
It Full !
Wash
only full loads of clothes and dishes, but do not overload or
oversuds. Wash clothes in cold or warm water and rinse in cold.
Always remember to vent your clothes dryer to the outside.
Keep your freezer full, even if only with containers of water,
to keep it operating at peak efficiency. If you have a second
freezer or refrigerator, be aware that it may be costing you
more than $20 per month. Remember to vacuum the condenser coils
on your refrigerator or freezer every three months. Also, replace
your refrigerator door seal when it becomes worn. To keep your
freezer running efficiently, defrost it whenever the ice inside
gets to be a quarter inch thick.
Use small cooking appliances like microwaves, frying pans, and
crock pots. Save the big appliances for the big jobs.
Make
It Happen !
The
most important thing you can do to increase your home's energy
efficiency is to determine what your needs are, make a plan,
and do it! You may not do everything at once, but each improvement
will add to your comfort and increase your savings!

Why
Have an Energy Efficient Home?
- Utility
expenses are one of the largest costs of home ownership
after the mortgage.
- Energy
efficient homes save money on utility bills and provide
greater comfort.
- Reduces
environmental pollution.
What
is A Home Energy Rating?
- A
measurement of a home's overall energy efficiency by a
Home Energy Rater, similar to knowing the miles per gallon
rating for your car.
- Data
is recorded and analyzed from the energy using and energy
saving features of the home.
- The
information is then translated into a multiple point system
and given a specific energy rating depending on the number
of points the home achieved.
- The
energy ratings range from 1 STAR to 5 STAR (0-100 points).
- The
average rating fee is about $350.00. Some rating fees
may be incorporated within your mortgage costs--check
with your local lending institution for details.
What
Are the Benefits of an Energy Rating?
- To
pinpoint specific areas that are wasting energy and money.
- To
participate in various Home Energy Loan and Energy Mortgage
programs.
- To
know before you buy a home whether it's energy efficient
or an energy waster.
- To
offer as a valuable selling point for a home.
What
Are the Benefits to the Housing Industry?

Why
Should the Mortgage Industry Be Interested in Home Energy Ratings?
A
20% national market penetration in energy ratings would result
annually in:
- 1.6
million homes rated
- a
minimum 11% increase in first-time buyer activity
- an
$8 billion investment in energy improvements
- additional
mortgage payments of $640 million, higher resale value
and,
- the
creation pf 50,000 full-time jobs
(Data
from: Indiana Office of Energy Policy, 1985 and "The
Effect of the Shelter Industry Energy Rated Homes System on
Home Ownership", Harvard/MIT, 1985)
What
is an Energy Efficient Mortgage (EEM)?
- An
EEM allows the home buyer to finance 100% of the energy
improvements.
- Works
best when a Home Energy Rating System documents the relative
efficiency the home.
- FHA
allows home buyers to finance the energy efficiency of
a new home above its appraised value when the home energy
rating documents of the home exceeds the Current Energy
Code in place in that area.
- Through
this program, home buyers can purchase homes whose prices
exceed FHA limits.
Energy
efficient mortgages offer opportunities to:
- Help
more lower and middle class families achieve the dream
of home ownership.
- Purchase
higher quality and more affordable housing.
- Create
a market demand and value for energy efficient homes.
- Catapult
new construction standards above minimum energy codes.
The
Buyer of an Energy Efficient Home Can Get a Bigger Mortgage
Loan and More Easily Afford a Dream Home!
What
is an Energy Improvement Mortgage (EIM)?
- Energy
Efficient Mortgages finance cost-effective energy improvements
at the time of sale or refinancing.
- A
home energy rater inspects the home and recommends cost-effective
improvements.
- The
funds for the improvements are placed into an escrow by
the lending institution.
- A
post-improvement rating is performed to confirm the improvements
were installed. The lending institution then releases
the escrow funds to pay for materials and contracted labor.
- The
FHA and VA Energy Improvement Mortgage programs can finance
improvements above the appraised value, if the measures
are shown to be economical.
Energy
improvement mortgages offer home buyers of existing homes opportunities
to:
- Upgrade
the homes they are buying immediately without tapping
the family's savings or taking out a higher interest,
home improvement loan.
- Own
a more comfortable home that costs less to heat and cool.
- Net
a better return when selling because of the higher resale
value.

What
are some methods of measuring duct leakage in a house?
METHODS OF MEASURING DUCT LEAKAGE
METHOD |
DIAGNOSTIC EQUIPMENT NEEDED |
GENERAL DESCRIPTION OF
TEST PROCEDURES |
Simple Subtraction |
Blower Door |
Pressurize house and all ducts (recommend 50 Pa). Record
Cfm 50 level.
Tape off all supply and return registers and grills. Pressurize
house again (same level if possible). Record Cfm 50 level.
Untaped Cfm 50 – tapes Cfm 50 = leakage in Cfm 50. |
Modified Subtraction |
Blower Door & Digital Pressure
Gauge |
Same procedure as above, plus a measurement of pressure
inside the taped ducts is taken with reference to the house
to account for additional leakage from the inside of the
house that communicates with the duct system and eventually
ends up outside.
(You are not taping stairways, baseboards, or sheetrock
penetrations that may communicate with the duct system,
so they are leakage points that are not counted by the Simple
Subtraction method used above. |
Flow Hood |
Blower Door & Flow Hood |
Tape off all supply registers and return grills except
the largest and least restricted return.
Pressurize the house to 50 Pa (Pascals) with the Blower
Door.
Place the Flow Hood up to the open return and measure the
flow. The duct leakage is in Cfm 50. |
Total Leakage Calculations (Duct leakage
to Inside + Duct Leakage to Outside = Total Duct Leakage) |
Duct Blaster |
Tape off all supply registers and return grills except
for the largest and least restricted return.
Install the Duct Blaster on the return selected.
Pressurize the duct system to 25 or 50 Pa.
Duct leakage will be in Cfm 25 or 50Pa. |
Leakage to Outside |
Blower Door & Duct Blaster |
Save as above, except pressurize the house to 25 or 50
Pa with the Blower Door and pressurize the ducts to the
same chosen static pressure with the Duct Blaster simultaneously.
Duct leakage is Cfm 25 or 50 measured to the outside only. |
