Flashcards in Air Concept Deck (218)
The Air Concept contains xx features that address design choices and policies.
The first xx features are predominantly preconditions, except for one optimization for New and Existing Interiors in Feature 08.
Set of symptoms, such as headaches, fatigue, eye irritation, and breathing difficulties, believed to be caused by indoor pollutants and poor environmental control that typically affects workers in modern airtight office building
Sick building syndrome (SBS)
Known as demand controlled ventilation, is ventila-tion provided by mechanically powered equipment, such as motor-driven fans and blowers, but not by devices such as wind-driven turbine ventilators and mechanically operated windows.
Can be vectors for mold growth and can easily spread contaminants such as dust.
Mechanical ventilation systems
Movement of air into and out of a space primarily through intentionally provided openings (such as windows and doors), through nonpowered ventilators, or by in filtration.
Can easily allow the infiltration of humidity and air pollution, such as tobacco smoke and outdoor chemicals
Natural ventilation systems
Feature 01, Air Quality Standards, is a precondition for
all three project types that limits the levels of indoor air pollutants.
The levels of volatile organic compounds (VOCs) in an indoor environment can be xx times higher than outdoor levels
The release of chemicals or particulates into the air from substances and solvents used in the manufacture of a building product.
A colorless gas compound that is used for manufacturing melamine and phenolic resins, fertilizers, dyes, and embalming fluids
Air Concept Part 1a requires that a project limit the levels of formaldehyde in the air to
less than 27 parts per billion (ppb).
Contains carbon and hydrogen that evaporates and diffuses easily at ambi-ent temperature and is emitted by a wide array of building materials, paints, wood preservatives, and other common consumer products.
volatile organic compound (VOC)
Air Concept Part 1b requires that a project limit the levels of VOCs in the air to
less than 500 micrograms per cubic meter (µg/m3).
A colorless, odorless, and highly poisonous gas formed by incomplete combustion. It replaces oxy-gen in hemoglobin, which limits the ability of blood to deliver oxygen and can lead to death.
Part 2a requires that a project limit CO levels to
To less than 9 parts per million (ppm).
Complex mixture of elemental and organic carbon, salts, mineral and metal dust, ammonia, and water that co-agulate together into tiny solids and globule
Particulate matter larger than 2.5 micrometers (µm) and smaller than 10 µm in diameter.
coarse particle (PM10)
Particulate matter 2.5 µm or smaller in di-ameter.
fine particle (PM2.5 )
Part 2b requires that a project limit PM2.5 levels in the air
to less than 15 µg/m3.
Part 2c requires that a project limit PM10 levels in the air to
less than 50 µg/m3
Triatomic form of oxygen that is hazardous to the respiratory system at ground level. It can be released into the air by photocopiers, printers, and air cleaners.
Part 2d requires that a project limit the ozone level in the indoor air to
less than 51 ppb.
Radioactive, carcinogenic noble gas generated from the decay of natural deposits of uranium.
Part 3 requires that a project limit the radon levels at its ____ level to _____
lowest occupied levelless than 0.148 Bq/L (4 pCi/L)
Feature 2 Part 1 Indoor Smoking Ban
No smoking within the building
Part 2: Outdoor Smoking Ban of Feature 02 requires the placement of signs that indicate a smoking ban near entrances and in specific exterior spaces. These signs must indicate that smoking is banned within
within 7.5 m (25′) of all entrances, operable windows, and building air intakes.
Part 2 also requires signs that educate oc-cupants about the hazards of smoking in the specific areas where smoking is allowed (beyond the 7.5 m [25′] distance). These signs should be
placed on all walkways within the area in intervals of 30 m (100′) at the mos
Part 1: Ventilation Design of Feature 03 uses which standard?
ASHRAE Standard 62.1-2013, Ventilation for Acceptable Indoor Air Quality
