Chapter 10: Indoor Environmental Quality Flashcards
ANSI/BIFMA e3-2011
A furniture sustainability standard developed by a joint committee of stakeholders using a consensus process described by the American National Standards Institute (ANSI).
ASHRAE 55-2010
A standard that defines the range of indoor thermal environmental conditions acceptable to majority of occupants, but accommodates an ever-increasing variety of design solutions intended both to provide comfort and to respect today’s imperative for sustainable buildings.
ASHRAE 62.1-2010
A standard that specifies minimum ventilation rates and other measures intended to provide indoor air quality that is acceptable to human occupants and that minimizes adverse health effects, and is the recognized standard for ventilation system design and acceptable indoor air quality.
Bake-out
A process used to remove airborne contaminants from a building caused by the off-gassing of furniture, paints, adhesives, sealants, carpets, wall-coverings, and other building materials by increasing the temperature in the building before it is occupied.
Carbon Dioxide (CO2) Concentration
A measurement of indoor air quality that determines the safety of a space for human occupancy depending on whether CO2 concentrations greater than 530ppm above outdoor air quality are present.
CIBSE AM10
The Chartered Institution of Building Services Engineers (CIBSE) Applications Manual (AM10) is a standard that defines the process for natural ventilation in nondomestic buildings.
Circadian Rhythms
The natural pattern of physiological and behavioral processes that are timed to a near 24-hour period.
Contaminant
An airborne particle that has qualities that would adversely affect human health should it be inhaled.
Cubic Feet per Minute (CFM)
The measurement used to determine airflow rates.
Daylighting
The purposeful amount of natural daylight in a building that decreases the amount of electrical lighting required.
Flush-out
A process used to remove airborne contaminants from a building caused by the off-gassing of furniture, paints, adhesives, sealants, carpets, wall-coverings, and other building materials by flushing out all the interior air several times with outdoor air.
Greenguard Certification
A program that gives assurance that products designed for use in indoor spaces meet strict chemical emissions limits, which contributes to the creation of healthier interiors and gives credence to manufacturers’ sustainability claims with empirical scientific data from an unbiased, third-party organization.
Mechanical Ventilation
The process of supplying, directing, and removing air from an indoor space b mechanical means.
Minimum Efficiency Reporting Value (MERV)
A rating system that ranges from 1 (low) to 16 (high) for filters made for a mechanical building ventilation system that filters particulates and airborne contaminants out of the air.
Natural Ventilation
The process of supplying, directing, and removing air from an indoor space by natural means, meaning without the use of a fan or other mechanical systems.
Occupant Comfort Survey
A survey distributed electronically or on paper to building occupants to determine their comfort level with building temperature, airflow, acoustics, and lighting.
Off-gassing
The emittance of volatile organic compounds (VOCs) from building elements such as flooring, wall-coverings, furniture, paints, adhesives, and sealants.
Sick Building Syndrome (SBS)
A series of symptoms connected with the phenomenon of building occupants feeling sick when they are in a building and recovering they leave the building.
Thermal Comfort
The range of indoor air temperature that most building occupants are comfortable at as prescribed by ASHRA 55-2010.
Ventilation Rate
The amount of air circulated through an indoor air space measured by air changes per hour as set by the ASHRAE 62.1-2010 baseline.
Volatile Organic Compounds (VOCs)
Organic chemical compounds that are emitted as gases from certain solids or liquids that evaporate under normal indoor atmospheric conditions for temperature and pressure and may have short and long-term adverse health effects. VOCs may be emitted by paints, glues and adhesives, cleaning supplies, building materials, office furnishings, copiers, and printers.
