BPI EP (60) Practice Questions and
Answers
2 lumber rot treatements - ANSWER-- chromatid copper arsenate (CCA) - its toxic,
contains arsenic, poisonous
- alkaline copper quaterney (ACQ) - less toxic, water based, fungicide and insecticide
according to BPI standards what should be the top priority for air sealing in a home? -
ANSWER-attic leakage paths
air leakage requires ... - ANSWER-a hole and a pressure difference across that hole
ammonium sulfate - ANSWER-added to cellulose insulation as a flame retardant. is it
also corrosive to metals when wet
at what ambient CO level would cause a building to be immediately evacuated -
ANSWER-70 ppm
balloon framed homes are typically energy inefficient because - ANSWER-they do little
to stop interstitial airflow
blower door test indicates a leakage below the buildings airflow standard. If your
partition wall cavities are open into the attic, what is the correct approach? - ANSWER-
seal the openings and evaluate the need for mechanical ventilation
cold air enters from - ANSWER-below the neutral pressure plane
determine peak electrical energy demand - ANSWER-the highest total wattage of the
electrical operated devices in use at a given time
fiberglass insulation requires - ANSWER-baffles to block airflow and work properly
Given the following conditions. Based pressure= -0.5 Pa, worst-case pressure = -4.5
Pa. What is the net worst-case depressurization? - ANSWER--4.0 (difference between
the 2)
IAQ issues can occur when the surface is at or below dew point due to lack of insulation
- ANSWER-
in buildings with attached garages which should be done to ensure health and safety -
ANSWER-eliminate pollutant pathways into the living space
