Blower Door Testing (included)
The purpose of the blower door test is to measure the air tightness of a building. The air tightness of a house is directly correlated to the energy use and comfort of the structure. Used to measure air-leakage rates; determine mechanical ventilation requirements; and identify leakage and weakness in the air pressure boundary that, if addressed, could result in energy savings, improved air quality, or avert mold and moisture damage.

Duct Blaster (optional)
Leaks in forced air duct systems are now recognized as a major source of energy waste in both new and existing houses. Studies indicate that duct leakage can account for as much as 25% of total house energy loss, and in many cases has a greater impact on energy use than air infiltration through the building shell. Just as important, duct leakage can prevent heating and cooling systems from doing their job properly, resulting in hot or cold rooms, and humidity problems. Worse yet, duct leaks can create air quality problems by pulling pollutants and irritants directly into the house. A Duct Blaster is used to directly pressure test the duct system for air leaks, much the same way a plumber pressure tests water pipes for leaks. The Duct Blaster fan is first connected to the duct system at the air handler cabinet, or a return grille. After temporarily sealing all remaining registers and grills, the Duct Blaster fan is turned on to force air through all holes and cracks in the ductwork. The fan speed is increased until a standard test pressure is achieved in the duct system. A precise leakage measurement is then made using an airflow and pressure gauge connected to the Duct Blaster system. Estimates of efficiency losses from duct leakage can then be made from the leakage measurements.
Infrared Scanning (optional)
View building components, shows the difference in temperature of building
components and inside building cavities To identify areas of energy waste infrared imaging has quickly become a valued tool in identifying problems related to energy loss, missing insulation, inefficient HVAC systems, radiant heating, water damage on roofs, and much more. A thermal imaging camera identifies patterns of heat loss that are invisible to the naked eye. Thermal imaging will quickly indicate the air leaks within a property and measurement data are easily compiled into a report. Air Tightness and Thermal Imaging testing are important quality control measures when building or renovating a house. Heat losses in buildings can account for up to 50% of the total energy consumption and comes from air leakage through chimneys, attics, wall vents and badly sealed windows/doors, etc.
Combustion Safety & Efficiency Testing (included)
Including a procedure called worst-case CAZ (combustion appliance zone)
depressurization, that involves depressurizing the house with its existing
exhaust appliances (i.e., exhaust fans and laundry dryers) to create a
worst-case negative-pressure condition. While under worst-case conditions,
one tests the combustion appliances’ ability to draft safely. Carbon monoxide
analysis and draft and spillage tests on combustion appliances are also performed.
Appliance Consumption Testing (included)
Used to measure electricity usage
Exhaust Pan Testing (included)
The Exhaust Fan Flow Meter is designed to make quick and accurate measurements of air flow through residential exhaust fans. During the measurement procedure, the Metering Box is placed directly over the grille of an operating exhaust fan and the airflow reading (in cfm) is displayed on the DG-700 pressure gauge
Used to determine if proper exhaust ventilation is adequate
Humidity & Temperature Testing (included)
Instruments used to measure humidity and moisture content and identify areas that are susceptible to mold growth.
Numerical Analysis (included)
Measure the home’s exterior horizontal dimensions, wall height, floor area, volume, and area of windows and doors
Determine the compass orientation of the home
Extract monthly energy consumption from utility bills
Calculate heating, cooling, water heating, and electric baseload energy use
In some cases, calculate an energy index for the home
Computer Modeling (22 Page Report, see example) (optional)
