Welcome to Energy Smart!
Chalet style home in Aspens west end. The owner is planning a renovation with efficiency
upgrades in mind. Currently in the planning stage. The assessment was completed as a
beginning baseline. Air sealing would be a huge improvement.

Recommended Upgrades Your Energy Smart Analyst:
Charles Cady
(970) 379-2961
When your Analyst performed your Home Energy Assessment, information was collected to estimate annual energy savings on projects you might consider completing to save
money on your energy bills. Below is a breakdown of those suggested improvements, the estimated costs and potential annual savings, which were calculated through software
modeling. A Savings to Investment Ratio (SIR) of 1 or greater means that the resulting energy savings will pay for the cost of the project.

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 1.05, this means that about
105.00 % of the air in your home is lost to the
outside every hour.
Infiltration at the upper level door.Infiltration at the sill plate .Blower door set up for the
pressure test.
Recommendations:
Air infiltration observed at exterior doors, attic access, windows and trim, switches, outlets and sill plates.
Exterior doors need new weatherstripping to replace the old.
The attic access should be weatherstripped to keep out unwanted attic air.
Windows and trim should be caulked to seal. Window replacement would be optimum.
Switches and outlets can be sealed with gaskets and caulk to reduce infiltration.
Sills and baseboards need to be caulked also.

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.

Single pane window with signs of
deterioration .
Double pane replacement doors
with broken seals.
Large expanses of single pane
glass .
Recommendations:
Single pane windows are quite inefficient. Currently the windows have insulating shades and most have
plastic window kits. Replacement would be optimum.

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.
Sealed combustion gas boiler Uninsulated heat pipes
Recommendations:
All exposed heat pipes should be insulated to reduce heat loss.

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.

Lighting & Appliances
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
ENERGY STAR
