BPI Test Questions and Answers1st Law of Thermodynamics - ANSWER-energy moves from place to place; energy
changes form one form to another; energy cannot be created or destroyed
Energy moves around and changes form.
2nd Law of Thermodynamics - ANSWER-energy flows naturally from high
concentrations to low concentrations
HEAT moves from warmer to cooler; AIR moves from higher pressure to lower
pressure; MOISTURE moves from wetter to drier
Active solar or Solar Thermal - ANSWER-uses solar energy to heat water
AFUE applies to - ANSWER-furnaces and boilers
AFUE ratings range from - ANSWER-68% to 72% on old, low-efficiency appliance all
the way up to 97% on high-efficiency models
Air conditioner refrigerant - ANSWER-readily changes form from a liquid to a gas, and
vice versa. The refrigerant transfers heat from indoor air to out door air
Air exchange Rate - ANSWER-the number of time the interior volume of air changes
over in one hour (air changes per hour, or ACH).
Formula: ACH = CFM x 60 / volume
air flow - ANSWER-the movement of air; air transfer
airborne moisture - ANSWER-as heat moves through air (convection), so too does
moisture. it's the fastest and easiest way moisture moves around the home
Annual Fuel Utiliztion Efficiency (AFUE) - ANSWER-the efficiency of a furnace or boiler
is most commonly expressed
This is a measure of how efficiently the appliance converts fuel to heat, on average,
over typical year
expressed as a percentage; it is the ratio between the appliance's output capacity
compared to it's input capacity
Assessing Existing Insulation - ANSWER-Good: no gaps or imperfections are present
Fair: there are gaps in over 2.5% of the insulated area; this equals a 3/8-inch space
along a 14.5-inch batt
,Poor: there are gaps in over 5% of the insulated area; this equals a 3/4-inch space
along a 14.5-inch batt.
Atmospheric Vent - ANSWER-combustion by-products exhaust from the house up
through a chimney by the stack effect due to natural buoyancy of hot gases
Attached garage - ANSWER-BPI first priority for air sealing between the garage and
house bc of occupant health and safety
average R-value - ANSWER-you must convert the $-value to a U-value. R-values and
U-values are inversely proportional to one another: as $-values increase, U-values
decrease and vice versa.
U=1/R (and R= 1/U)
balloon framing - ANSWER-has continuous wall cavities from the basement to the attic
baseload - ANSWER-home's electricity and water demand
baseloads can be reduced by - ANSWER-energy-efficient lighting appliances and
electronics
water-saving measures such as low-flow showerheads and faucet aerators
Bay - ANSWER-the space between and the size of the wood influence the cavity or bay
(indicates the amount of insulation)
Before attempting any of the air sealing work, it is important to: - ANSWER-Walk
through the home and map out the sites as you discover t hem
Move aside existing insulation
Clean the area; otherwise, the foam or chalk will not adhere to the surfaces
boiler systems - ANSWER-heats water to produce either steam or hot water fro heating.
Steam is distributed through pipes to steam radiators; hot water can be distributed
through baseboard radiators or radiant floor systems, or can heat air via a coil
