BPI EXAM/ACTUAL EXAM QUESTIONS
AND ANSWERS 100% PASS
How should energy auditors approach assessing a home? - ANS Use the house as a system to
approach to assessing a home.
Core concepts of home performance - ANS Don't insulate unless you air seal.
Don't air seal unless you insulate.
Don't air seal unless you have air for the fire.
Don't know if you have air for the fire until after you air seal.
Don't put good air in bad places.
What does the national fire protection association's national fuel gas code (NFPA 54) state that
combustion air must be provided for any combustion zone? - ANS Where the collective fuel
input exceeds 1,000 BTU per 50 cubic feet.
What are the three goals all building scientists should strive to achieve? - ANS Increased IAQ
= healthy indoor conditioned spaces.
Use low flow shower/faucet heads
Decrease heating/cooling system use
What is the square footage of the living room, kitchen, bedroom, dining room, garage,
sunroom, total area, and the value of y in a home (in ft2)? When the base and height are 35/30,
20/30, 35/35, 20/35, 12/35/30/9/12/56, 12/9/2, 1050/600/1225/700/672/54 - ANS Living
room (1,050), kitchen (600), bedroom (1,225), dining room (700), garage (672), sunroom(54),
total area (4,301)

What are the categories of potential for energy conservation and how do you define them? -
ANS Heating and cooling - seasonal efficiency for fossil-fuel heating systems range from 30 -
90%. Most older systems operate at the mid-to-lower end of this scale.
Air leakages - infiltrating air must by heated or cooled to a comfortable temperature, and
heated and cooled air is lost when air leaks out of the building.
Water heating - energy losses in heating and storage of hot water can amount to 40% or more
of that system's energy consumption.
Appliances and Lighting - refrigerators, lights, entertainment systems, computers and other
appliances use considerable electrical energy because of obsolete design, careless operations,
or just the sheer number of electrical devices in a home.
Residential Behavior - The awareness and care of a buildings residents and managers has a
significant influence on how much energy the building uses.
What are the cost effectiveness formulas? - ANS Simple payback: PB (measured in years) = C
(the initial cost in dollars)/S(the annual savings in dollars).
Life-cycle savings: Sic= S (the annual savings in dollars) * L (the life expectancy of retrofit
(measured in years).
Savings to Investment Ratio: SIR= Sic(measured in current dollars)/C(the initial cost in dollars).
A homeowner spends $12,000 on an energy retrofit and the energy bill is reduced by
$100/month. What is the SIR, PB, and Sic if there is a life expectancy of 11 years? - ANS SIR =
1.1, PB = 10 years, SIC = 13,200
How do you define energy? - ANS A measurable quantity of heat, work, or light.
What is potential energy? - ANS Stored energy, like a cord of wood.
What is kinetic energy? - ANS Transitional energy, like a flame.
What does potential energy turn into? - ANS Kinetic energy
