Drainage plane - The space between the exterior cladding and the wall in cavity-wall construction,
designed to prevent water from penetrating the wall assembly.
Cavity-wall construction - A building construction method with a space between the exterior cladding
and the wall, allowing for drainage and moisture management.
Innermost building envelope component material - The material within the building envelope that is
closest to the interior space, affecting the indoor comfort and energy efficiency.
Outermost building envelope component material - The material within the building envelope that is
closest to the exterior, providing protection against weather and environmental elements.
Flashing - A waterproof material used to prevent water from penetrating the wall assembly by
redirecting it away from vulnerable areas.
Simple payback calculation - A calculation that determines the time it takes to recoup the costs of a
project based on the savings generated by the project.
Material Cost - The cost of materials required for a project, including the purchase and delivery
expenses.
Labor Cost - The cost of labor required for a project, including wages, benefits, and any additional
expenses related to the workforce.
Annual Savings - The amount of money saved per year as a result of implementing a project or energy-
efficient measures.
Ambient CO level - The level of carbon monoxide present in the surrounding air, which can be harmful to
human health if it exceeds safe limits.
, Immediate termination of the inspection - The point at which the inspection must be stopped due to
high levels of carbon monoxide, ensuring the safety of the inspector and others present.
Water heater venting - The process of safely removing combustion gases from a water heater to prevent
the buildup of carbon monoxide and other harmful byproducts.
Chimney liner - A protective lining installed in a chimney to improve venting efficiency and reduce the
risk of fire hazards.
Power venter - A device used to assist in the proper venting of combustion gases, ensuring the safe
operation of fuel-burning appliances.
Venting table - A reference table that provides guidance on the proper venting requirements for
different types of combustion appliances.
Flue pipe - A pipe that carries combustion gases from a combustion appliance to the outside, preventing
their release into the living space.
Vapor barriers (retarders) - Materials used to slow the diffusion of moisture through building materials,
preventing condensation and moisture-related issues.
Indoor air contaminants - Pollutants present in the indoor air that can negatively impact the health and
well-being of occupants, requiring proper ventilation and filtration.
Bulk moisture - Excessive moisture that can enter building assemblies, leading to structural damage,
mold growth, and compromised indoor air quality.
Air leakage - Unwanted air movement through the building assemblies, which can result in energy loss,
discomfort, and decreased indoor air quality.
Carbon monoxide detector - A device that detects the presence of carbon monoxide gas, providing an
early warning to occupants and preventing potential health hazards.
