BPI BUILDING ANALYST FINAL PAPER 2025/2026
QUESTIONS WITH ANSWERS GRADED A+
✔✔Efficacy - ✔✔Light output-per-power input measured in lumens per watt. It is
calculated by dividing light output measured in lumens by electric input in watts.
Incandescent is the least efficient; low pressure sodium is the most efficient.
✔✔Refrigerator settings savings - ✔✔Hot climate
- fresh food from 36.4 to 43.9
- freezer food from 9.1 to 12.4
Saves 200 kWh/yr
✔✔New Showers - ✔✔1.75 gpm saving 44% or 12.75 gallons a day
✔✔Flow Optimized Aereators - ✔✔1.5 gpm saving 47% or 11.4 gallons a day
✔✔Simple Payback - ✔✔The most basic metric, and is the cost divided by the annual
savings in dollars.
✔✔Payback - ✔✔Cost / Savings
✔✔Always deal with moisture at - ✔✔the source.
✔✔Most effective way to deal with moisture - ✔✔Source Control
✔✔Thermal Comfort - ✔✔State of mind that expressed satisfaction with the surrounding
environment.
✔✔Thermal Comfort Factors - ✔✔1. Air Temperature
2. Radiant Temperature
3. Air Velocity
4. Humidity
5. Clothing
6. Body Metabolism
✔✔EPA suggested maximum 8 he exposure to CO - ✔✔9 ppm
✔✔CO is caused by - ✔✔incomplete combustion.
✔✔Blue Flame - ✔✔Complete Combustion
✔✔Key to a building performing efficiently is - ✔✔alignment of the thermal and pressure
barriers.
, ✔✔House-as-system - ✔✔Interactions between all of the components of a home and
their relationships to heat loss, heat gain, and comfort.
✔✔Diagnostic Audits - ✔✔Include a blower door, infrared scans, duct blasters, and any
other applicable evaluation tools. Some include building modeling software.
✔✔Walkthrough Audits - ✔✔Include visual inspections, and sometimes utility, usage
reviews.
✔✔Diagnostic evaluations must be aborted if - ✔✔ambient CO concentrations greater
than 70 are recorded.
✔✔Conduction - ✔✔Dominant heat flow mechanism in solid materials with stationary
molecules (direct contact).
✔✔Radiation - ✔✔Energy that comes from a source and travels through space.
✔✔Q = U•A•T - ✔✔Heat Loss
✔✔Vapor barriers stop - ✔✔the migration of water via vapor diffusion.
✔✔Air barriers stop air via - ✔✔infiltrations and exfiltration.
✔✔Convection - ✔✔Bulk movement of heat through fluids.
✔✔Thermal barriers keep the structure - ✔✔warm to prevent condensation from forming
in the first place.
✔✔Warm humid air - ✔✔condenses when it reaches cold enough surfaces.
✔✔Attic insulation should be installed - ✔✔with a blown product.
✔✔99% of moisture is - ✔✔carried by air movement.
✔✔Most effective way to deal with moisture and pollutants. - ✔✔Source Control
✔✔Relative Humidity - ✔✔Amount of water vapor in air relative to the total amount of
water vapor it is capable of containing expressed as a percentage.
✔✔Vermisculate - ✔✔may contain asbestos.
✔✔SIR - ✔✔Cost / Annual Savings
