29 AIR Features
12 Preconditions
Carbon filters are designed to…?
absorb volatile pollutants and remove the largest particles
These filters are meant to address smaller particles
Media Filters

Vapor Diffusion
What documentation is required for 14 Air Infiltration Management?
Annotated Document
Commissioning Report
What heating/cooling system may be preferable in arid environments because it doesn’t further dry out the air?
Radiant heating and cooling
An increase in relative humidity of what % can increase the emissions of what?
a 35% increase
the emission of formaldehyde by factor of 1.8-2.6
High humidity may promote the accumulation of growth of…
Microbial pathogens including bacteria, dust mites, and mold

What is one of the most widely used pesticides, that is a suspected endocrine disruptor associated with cardiovascular problems?
Atrazine
What widely used herbicide, to which long term exposure, may lead to kidney problems and reproductive difficulties?
Glyphosate
Exposure to this can have neurotoxic effects and in early development is associate with negative effects on memory, IQ, learning and behavior
Lead
Exposure to this through inhalation can occur when building materials degrade over time or are disturbed during renovation or demolition, and is associated with lung cancer and mesothelioma
Asbestos Fibers
This feature requires the use of ultraviolet germicidal irradiation (UVGI) devices to manage mold and bacteria on cooling coils as well as inspections for signs of mold outside of the air handling system
