Blower Door Testing

Only.....$220.00

The Largest Missouri Home Energy Auditing Service
In Central Missouri

Blower Door Set up at the front door.

When do I need to have an Energy Audit?

The best time to have an Energy Audit service is when you are planning on buying a
home, New homes included. The seller can make the option to have the energy
audit done before the home goes on the market. Once the repairs are complete, A.E.P.I. will
reevaluate the home with another test, to make sure all repairs have been properly
completed to give the home a seal of an energy efficient home to move into.

Package Price:

The Blower Door Test $200.00
The Energy Audit is $185.00 save $50.00 if you include both Blower Door test
and the Energy Audit combined.
This service does NOT include any Basic Home Inspection services, if you would like
to add a Home Inspection please call me for a quote. Special Rates available

This service Starts June 6th 2008....Call to make an appointment.

Professional energy auditors use blower door tests to help determine a home's airtightness.

These are some reasons for establishing the proper building tightness:

Reducing energy consumption due to air leakage
Avoiding moisture condensation problems
Avoiding uncomfortable drafts caused by cold air leaking in from the outdoors
Making sure that the home's air quality is not too contaminated by indoor air pollution.

How It Works

A Blower Door is a powerful fan that mounts into the frame of an exterior
door. The fan pulls air out of the house, lowering the air pressure inside.
The higher outside air pressure then flows in through all unsealed
cracks and openings. The auditors may use a smoke pencil to detect air
leaks. These tests determine the air infiltration rate of a building.

Blower doors consist of a frame and flexible panel that you can place
in a doorway, a variable-speed fan, a pressure gauge to measure the
pressure differences inside and outside the home, and an airflow
manometer and hoses for measuring airflow.

Diagram of a blower door. The parts of the blower door are labeled as follows: exterior door frame (around the outside edge of the door), temporary covering (over the surface of the door), and adjustable frame (just inside the exterior door frame). An air pressure gauge, a small vertical rectangle with three round gauges inside, is alongside of the door. The top gauge is connected by a tube to the temporary covering, and the bottom two gauges are connected to a fan sitting at the bottom of the door. The caption reads: Diagnostic Tools. Testing the airtightness of a home using a special fan called a blower door can help to ensure that air sealing work is effective. Often, energy efficiency incentive programs, such as the DOE/EPA ENERGY STAR® Program, require a blower door test (usually performed in less than an hour) to confirm the tightness of the house.

There are two types of blower doors: calibrated and uncalibrated. It is
important that auditors use a calibrated door. This type of blower door
has several gauges that measure the amount of air pulled out of the
house by the fan. Uncalibrated blower doors can only locate leaks in homes.
They provide no method for determining the overall tightness of a building.
The calibrated blower door's data allows the auditor to quantify the
amount of air leakage and the effectiveness of any air-sealing job.

Thermal Infrared Imaging

How They Work

Thermography measures surface temperatures by using infrared
video and still cameras. These tools see light that is in the heat
spectrum. Images on the video or film record the temperature
variations of the building's skin, ranging from white for warm regions
to black for cooler areas. The resulting images help the auditor
determine whether insulation is needed. They also serve as a
quality control tool, to ensure that insulation has been installed correctly.

A thermographic inspection is either an interior or exterior survey.
The energy auditor decides which method would give the best
results under certain weather conditions. Interior scans are more
common, because warm air escaping from a building does not
always move through the walls in a straight line. Heat loss detected
in one area of the outside wall might originate at some other location
on the inside of the wall. Also, it is harder to detect temperature
differences on the outside surface of the building during windy
weather. Because of this difficulty, interior surveys are generally
more accurate because they benefit from reduced air movement.

Thermographic scans are also commonly used with a blower door test
running. The blower door helps exaggerate air leaking through
defects in the building shell. Such air leaks appear as black streaks
in the infrared camera's viewfinder.

Thermography uses specially designed infrared video or still
cameras to make images (called thermograms) that show surface heat
variations. This technology has a number of applications. Thermograms of electrical
systems can detect abnormally hot electrical connections or components.
Thermograms of mechanical systems can detect the heat created by excessive
friction. Energy auditors use thermography as a tool to help detect heat losses
and air leakage in building envelopes.

Always ask for an Energy Auditing service before you get
stuck paying the big Heating or A/C bill
