Ventilation Rate
The rate at which indoor air enters and leaves a building.
ventilation
Process of supplying a building or room with fresh air.
Process of exchange of air between the ambient atmosphere and the lungs.
In physiology, the amount of air inhaled per day.
Oxygenation of blood.
Ventilation/Suction: The act of admitting fresh air into a space in order to replace stale or contaminated air; achieved by blowing air into the space.
Ventilation
In this guide, the movement of air between the inside and outside of a building usually through windows, doors and air vents built into the building's walls or ceilings.

Ventilation: The process of supplying and removing air by natural or mechanical means to and from any space. Such air may or may not be conditioned.
Viscosity: Friction or resistance to the flow of a liquid.
bottom ventilation
botulism Food poisoning due to the presence of a powerful exotoxin developed from botulinum bacteria.
boulder Any loose rock (sediment) larger than 256 millimeters (10 inches).
A ventilation system using heated or cooled water pumped through a building.
Hydrophilic
Having a strong affinity for water.
The lack of ventilation indoors concentrates air pollution where people are most exposed to them. Background pollution comes from such mundane sources as shower water mist containing arsenic or manganese, both of which are damaging to inhale.
Displacement Ventilation - A method of space conditioning where conditioned air is supplied at or near the floor.
Demand Control Ventilation Using Carbon Dioxide Sensors - A combination of two technologies: CO2 levels in the air inside a building, and an air-handling system that uses data from the sensors to regulate the amount of air admitted.
Positive Crankcase Ventilation (PCV): An emission control system for a reciprocating internal combustion engine that involves recirculating gases that blow by the piston rings during combustion from the crankcase back into the intake manifold so they ...
Used widely as a measure of the ventilation adequacy of a space. Carbon Footprint A measure of a particular item's impact on the environment in terms of the amount of greenhouse gas (GHG) produced, measured in units of carbon dioxide.
ventilation Atmospheric air circulation determined by wind speed and mixing height. The degree of ventilation is an indication of how well air pollution will be dispersed. volatile Any substance that evaporates at low temperature.
Ventilation Rate The rate at which air enters and exits a building or home.Vermicomposting Also known as 'worm composting,' vermicomposting can be accomplished in bins or pits and adapted for indoor or outdoor composting.
Passive heating strategies most often rely on the collection of heat from the sun during the day, while passive cooling strategies rely on heat gain avoidance and the use of cross ventilation, evaporation, ...
PCV stands for positive crankcase ventilation. Automobile makers began installing PCV systems in all new cars in 1963. It helps to recycle hydrocarbon contaminated gases inside the engine (blowby) back into the engine's combustion process.
Energy performance of a building is the amount of energy actually consumed or estimated to meet the different needs associated with a standardised use of the building, which may include, inter alia, heating, hot water heating, cooling,ventilation and ...
Pollution formed indoors can be reduced by ensuring that all gas appliances are working correctly. Good ventilation will improve indoor air quality by dispersing biological pollutants like dust mite, and other pollutants such as cigarette smoke.
Carbon Dioxide - Odorless gas commonly sourced by respiration, and which has been used widely as a measure of the ventilation adequacy of a space.
Carbon Monoxide - A colorless, odorless and highly toxic gas commonly created during combustion.
environmental management international standards = DD ISO/TS 21220:2009 Particulate air filters for general ventilation. Determination of filtration performance; See SAI Global ...
Radon: A colorless, naturally occurring gas formed by radioactive decay of radium atoms. Radon accumulating in basements and other areas of buildings without proper ventilation has been identified as a leading cause of lung cancer.
sick building syndrome - a human health condition where infections linger, caused by exposure to contaminants within a building as a result of poor ventilation.
A very poisonous, colorless and odorless gas formed when carbon-containing matter burns incompletely, as in automobile engines or in charcoal grills used indoors without proper ventilation.
Carbon tetrachloride (CCl4) ...
The data show that using better cooking devices and cleaner fuels, such as gas or electricity; improving ventilation; ...
Radon accumulating in basements and other areas of buildings without proper ventilation has been identified as the second leading cause of lung cancer.
Stack Effect: Flow of air resulting from warm air rising, creating a positive pressure area at the top of a building and negative pressure area at the bottom. This effect can overpower the mechanical system and disrupt building ventilation and ...
The organization publishes recommendations on ventilation, air sampling and air concentration guidelines (threshold limit values or TLVS) designed to control exposure of workers to chemicals, noise and radiation in the workplace.
