NOTES AND TERMS
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends a concentration of CO2 no more than 700 ppm above the ambient air (outside) concentration in order to minimize human odors and maintain comfort.
Carbon dioxide is a colorless, odorless gas. It is produced when any carbon-based material used for fuel (coal, oil, wood, etc.) is burned. When fuel burning is not a factor, the main sources are tobacco smoke, human and animal respiration. Carbon dioxide is given off whenever we exhale. Cars, trucks, industrial equipment, and burning fuel for power are some of the major contributors to CO2 in the air.
Ideally, CO concentrations indoors are expected to be the same as CO concentrations outdoors. CO concentrations are typically around one to two parts per million parts of air (ppm) or less. Concentrations are usually lower in rural areas. Finding CO concentration higher indoors than outdoors indicates an indoor source of CO, or a source very close to your home.
Carbon monoxide is an odorless, colorless gas often formed in the process of incomplete combustion of organic substances, including fuels. CO can cause serious health problems.
