BPI Building Analyst Exam Questions and Answers Latest Update 2025 Graded A+
Absolute humidity - Answers Air moisture content expressed in grains (or pounds) of water vapor per
pound of dry air.
Absorptance - Answers The ratio of a solar energy absorbed to incident solar. Also called absorptivity.
Absorption - Answers A solid material's ability to draw in and hold liquid or gas.
Air barrier - Answers Any part of the building shell that offers resistance to air leakage. The air barrier is
effective if it stops most air leakage. The primary air barrier is the most effective of a series of air
barriers.
Air changes at 50 pascals (ACH50) - Answers The number of times that the complete volume of a home
is exchanged for outside air when a blower door depressurizes the home to 50 pascals.
Air conditioning - Answers Cooling buildings with a refrigeration system. More generally means both
heating and cooling.
Air exchange - Answers The total building air exchanged with the outdoors through air leakage and
ventilation.
Air handler - Answers A steel cabinet containing a blower with cooling and/or heating coils connected to
ducts.
Asbestos - Answers A material made of brittle mineral fibers that damage lungs and other bodily tissues.
Annual fuel utilization efficiency (AFUE) - Answers A laboratory-derived efficiency rating for heating
appliances which accounts for chimney losses, jacket losses, and cycling losses.
Annual return - Answers The yearly savings divided by the initial cost needed to achieve the savings,
expressed as a percent.
Backdrafting - Answers Continuous spillage of combustion gases from a combustion appliance.
Backdraft damper - Answers A damper, installed near a fan, that allows air to flow in only one direction
British thermal unit (Btu) - Answers The quantity of heat required to raise the temperature of one pound
of water one degree Fahrenheit.
Capillary action - Answers The ability of water to move through materials, even upward against gravity,
through small tubes or spaces.
Carbon dioxide - Answers One of two main products of complete combustion of a hydrocarbon(Do you
recall the other?)
