BPI Building Analyst QUESTIONS AND
ANSWERS A+ GRADED
Types of indoor air pollutants
CO, Radon, Asbestos, Lead, Nitrogen Oxides, VOC (offgassing) dust particles, Mold,
Bacteria
Radon, What is it?
Decay of radioactive elements in the earth. Enters through cracks in holes and service
pipe penetrations. It can diffuse through concrete and brick and wood. Colorless,
Odorless, Tasteless.
Radon Limit in Water
4 pci/L of air. One billionth of a curi
Asbestos
Long thin fibrous mineral. Released into the atmosphere if disturbed. (Friable) held in
suspension in the air.
Most common places to find lead. When was it banned?
Paint, plumbing, flashing. Banned in 1978
What does mold require to live
Moisture, food source, right temp
Most common places to find mold
Places with high delta T and moist places
Carbon Monoxide, how is it formed?
Incomplete combustion. Colorless, odorless, tasteless
CO thresholds in air
Below 9ppm 24 hrs. Good. 35 PPM disable appliances., identify source. 35 ppm for 1
hr.
Clues for Carbon Monoxide
Carbon buildup, dirty burners, lazy flames, fails CO test.
What is correlated color temperature
Color appearance measured in degrees kelvin. Bulbs are stamped, <3200K warm,
3200-4000 Neutral. >4000 Blue White
Color Rendering Index (CRI)
measurement showing effect of a light source on the color of objects based on a 0 to
100 scale. Not all light sources propduce the right color compared to naturally
Luminous efficiency
How many lumens you get vs watts
incandescent
Low efficiency, most energy goes to heat, light produced by glowing tungsten wire
fluorescent
Requires ballast control, has mercury gas in it
Fluorescent Code on light F32T8
F Flourescent, 32 wattage, T bulb shape, 8 Diameter. Measure din 1/8ths of inch
Compact Fluorescent Lamp (CFL)
