Air Leakage
Energy Smart Tip:
Your analyst used a blower door fan to test for air leakage. This test helps determine how leaky or tight the
home is relative to other homes. Your home’s natural leakage rate is shown in the chart on the left. A very
leaky home costs more to heat, while a very tight home may require continuous mechanical ventilation. Leaks
can be repaired through attic floor sealing, caulking, weather stripping, and other means.

CF = Cubic Feet. The volume of air contained in a
1’ x 1’ x 1’ cube.
CFM50 = Cubic Feet per Minute at 50 Pascals
negative pressure. This number estimates how
much air your home loses each hour.
ACHn = Natural Air Changes per Hour. Expressed
in the chart above as 0, this means that about
0.00 % of the air in your home is lost to the
outside every hour.
Recommendations:
No blower door test conducted due to state of home and remodel progress with numerous air connections to
the outside. A blower door test would not produce meaningful information.
Make sure ERV filter is cleaned periodically and that there are easy wall mount controls wired to the unit for
ease of operation.

Energy Smart Tip:
Your home’s foundation is a very important part of its thermal performance. Increasing the level of insulation
on your foundation may be an important step to improve comfort. Sealing cracks and gaps can help to reduce
“stack effect” – a thermodynamic process that contributes dramatically to heat loss in your home. As a result,
it is recommended to always combine air sealing with any insulation project.
Upgrading Foundations – If your home is built over
a vented crawlspace, you can improve energy
efficiency, comfort and durability by upgrading the
foundation to a “conditioned crawlspace.” This
involves sealing and insulating the foundation
walls and rim and installing a sealed vapor barrier
on the ground.

Cantilevered below conditioned
space
Recommendations:
Cantilevered floor is made up of tongue and groove panels. Assuming there is not plywood/osb
sheathing or some other continuous air barrier behind the t&g, there is going to be air infiltrating between
seams of t&g. Seal all seams with caulk to reduce air infiltration/heat loss.

Envelope – Walls
Energy Smart Tip:
Walls make up the largest percentage of surface area facing the outside environment. Improving wall
insulation can be a challenge due to the limited space inside a wall and the difficulty accessing wall cavities. If
wall cavities are exposed during a remodel, consider fully insulating them with fiberglass batts. Insulation can
also be blown in through holes drilled through the exterior of the home. When replacing exterior siding, rigid
insulation such as foam board can be installed to minimize heat loss while also improving the wall’s R-value.
Thermal bridging – This term refers to the transfer
of heat through the structural components of your
home, like wood or steel beams, or other framing
elements.
R-value – Represents the capacity of an insulating
material to resist heat flow. The higher the R-
value, the greater the insulating power.
Lots of thermal bridges
Recommendations:
Consider spray foam to fill steel beam depressions to reduce thermal bridges.
If drywall was to be removed entirely, I would recommend spray foam full depth insulation. If only certain
areas are to be removed/replaced, leaving the 5.5” fiberglass batts would make more sense.

Energy Smart Tip:
Adding insulation to your attic can be one of the most cost-effective upgrades to your home. Be sure to air-seal
all connections between the attic and living space before installing additional insulation. Also be sure to protect
existing vents with baffles and complete any repair projects. And don’t forget to insulate and weather-strip the
attic hatch!
Upgrading roofs – Roofs are typically considered
for energy improvements when there is easy
access to the existing insulation, such as an attic
floor, or when you are re-roofing your home. In
some cases, rigid foam insulation can be added to
your roof deck to increase its thermal
performance, saving you money on utility bills and
making your home more comfortable.
12” roof cavity depth Flat attic area with R38 fiberglass Access hatch
Recommendations:
Cathedral ceilings are insulated with R38 fiberglass. If drywall is going to be removed in the entire ceiling
area, spray foam insulation should be considered. With double the r-value of fiberglass, spray foam
insulation could get the ceiling to current 2021 IECC standards.
Make sure the flat attic area has approximately 18” of insulation depth to achieve R60 - it’s currently 12” in
depth, or R38. And be sure the access hatch has insulation fastened to the back of the hatch door. Several
layers of rigid foam insulation glued/fastened to the hatch door works best.

Envelope – Windows & Doors
Energy Smart Tip:
Adding storm windows, insulating blinds or replacing your current windows can save energy and make your
home feel more comfortable. When replacing windows, install energy efficient units with a U-factor of .28 or
lower and ensure that the rough opening of the window is properly air-sealed with a low-expanding foam that
is approved for doors and windows.
U-factor – This number refers to the ability of your
windows to resist heat loss. It is the numerical
reciprocal of R-value.
Low-e – These coatings are applied to glass when
windows are manufactured and help to reduce the
window’s emissivity, which can improve insulating
properties when properly applied.
Gas filled – Noble gasses are used as an air
barrier between panes of glass to help increase a
window’s thermal performance. The seals that
keep these gasses trapped inside can fail over
time and should be inspected periodically.

The only recommendation is to add thermal insulated window treatments such as honeycomb blinds and
draw them down at night during winter months.

Heating & Cooling
Energy Smart Tip:
Your home’s heating and cooling systems were inspected for safety and efficiency. Older heating systems
should be replaced with energy efficient, sealed-combustion units or highly energy efficient heat pumps. This
is often a significant upgrade so considerations beyond energy savings should be made. ENERGY STAR
certified equipment will provide the best efficiency and savings.
AFUE – Annual Fuel Utilization Efficiency is the
measure of your heating system’s efficiency.
Higher numbers are more energy efficient.
SEER – Seasonal Energy Efficiency Ratio is the
measure of your cooling system’s efficiency.
Higher numbers are more energy efficient.
Recommendations:
Boiler assumed to be original to the build date of the home, making it 15 years old. It’s an 89% efficient unit.
The ideal scenario would be to replace this aging boiler with an electric air to water heat source pump. In the
meantime, insulate the exposed pipes with foam pipe insulation.
Condensers are assumed to be from 2015 based on what appear to be a hand written date on side of one of
the units. The units are between 13 and 14 SEER rated. Next time these need to be replaced, look towards
a cold climate heat pump that might work with the existing air handlers. In addition to more efficient cooling,
this would provide the option to heat with an efficient electric system as well.
Have the doors to the existing open gas fireplace replaced with sealed gasketed doors, or have a glass front
installed that turns the unit into one that is sealed. An open gas fireplace is like leaving a window open year
round.

Water Heating
Energy Smart Tip:
Many water heating systems are set to temperatures that are too high for safety and energy efficiency. Keep
your water temperature at 120˚F for optimum energy performance and to keep your family safe.
EF – Energy Factor is a metric used to compare
the energy conversion efficiency of residential
appliances and equipment. EF ratings vary by
appliance size and type, but in general, bigger
numbers are more energy efficient.
Recommendations:
Hot water heater is an indirect tank off the boiler. This is good setup. Insulate the pipes for a minor
efficiency improvement.

Health & Safety
Energy Smart Tip:
Energy Smart Colorado requires analysts to perform combustion safety tests on gas-fired equipment.
Problems with furnaces, boilers or water heaters may include but are not limited to: poorly-tuned burners,
combustion gas spillage (also called back drafting), gas leaks and improper venting. Any health and safety
issues identified by your Analyst should be a top priority and must be repaired by a qualified professional
before making efficiency upgrades to the home. *Caution: improper air-sealing may create safety issues.
CO – A byproduct of combustion, CO (Carbon
Monoxide) is a colorless, odorless and tasteless
gas that is slightly less dense than air. It is toxic to
humans in concentrations above 35 ppm.
Worst case – Your Analyst tested your heating
system under the "worst case" conditions for
proper operation. If your appliance fails this test, a
follow-up test is performed under “natural
conditions” to determine if there is a safety risk.
Recommendations:
With combustion appliances in the home, be sure to have carbon monoxide detectors on all floors of the
home.

Energy Smart Tip:
Replace incandescent and CFL lamps with LEDs. LEDs use about 20% of the energy and last up to 25 times
longer than traditional incandescent bulbs. They also contain no toxic mercury and turn on instantly. Your
refrigerator is usually one of the biggest consumers of electricity in your home. If your fridge is more than 10
years old, consider replacing it with an ENERGY STAR certified unit.
Tips to reduce kWh base-load:
1)Use smart power strips for big energy users
like home entertainment systems
2)Use laptop computers instead of big towers –
they use up to 90% less power
3)Upgrade all of your appliances as they age to

Extensive heat tape
Recommendations:
It appears all gutters and some roof eaves contain heat tape. Make sure heat tape is wired to inline timers
and programmed to operate for only 2-3 hours per day during the middle of the day (to get an assist from
warmer temperatures). Heat tape is a very large electric load and should be managed carefully.
Make sure all lights are LEDs. And be sure to select high efficiency Energy Star rated appliances.

Radon system Air handler for AC condenser
Understanding infrared (or thermographic)
images:
Energy analysts use infrared cameras to check
the effectiveness of insulation in a building's
construction.
Infrared images use light waves to interpret
surface temperatures and can be impacted by a
number of factors.
During a blower door test, air leakage can often be
identified by finger-like patterns around openings.
Areas with poorly-performing or missing insulation
will reflect the outside temperature relative to the
interior (generally lower temps in the winter or
higher temps in the summer.)
As a general rule, infrared images provide more
clarity when the outdoor air temperature is lower
than the indoor air temperature.
