✍️ Sample Certified Energy Auditor Certification Questions & Answers
1. A utility offers a $0.15/kWh rebate for verified electricity savings from an energy retrofit. If the project saves 200,000 kWh annually, what is the one-time rebate amount?
The rebate equals $0.15/kWh multiplied by 200,000 kWh, which equals $30,000.
2. Which metric is commonly used to express boiler efficiency as measured by the flue gas method?
Combustion efficiency using the stack loss method measures boiler efficiency by analyzing flue gas temperature and oxygen/CO2 content.
3. In evaluating a solar thermal system for domestic hot water, what does the 'solar fraction' indicate?
Solar fraction is the percentage of a building's total hot water (or space heating) energy demand provided by the solar thermal system, with the remainder supplied by a conventional backup source.
4. What is the significance of the building envelope's effective R-value compared to the nominal R-value of installed insulation?
Thermal bridging through framing, gaps in insulation installation, and air leakage all reduce the actual thermal performance below the nominal R-value printed on the insulation product.
5. For a fixed-tilt PV installation in the continental US, what is the general rule for maximizing annual energy production?
Setting the tilt angle equal to the local latitude and orienting panels toward true south maximizes annual solar energy capture for fixed installations in the Northern Hemisphere.
6. What is the primary risk of performing air sealing work without addressing combustion safety in a home with atmospheric-vented appliances?
Tightening the building envelope without ensuring adequate combustion air supply can cause atmospheric-vented appliances to backdraft, pulling dangerous combustion gases including carbon monoxide indoors.
