ICC Energy and Sustainability Professionals 2 — Questions and Answers
Question 1: Under IECC 2021, what is the minimum continuous air barrier requirement for commercial buildings regarding tested leakage?
- 0.25 cfm/ft² at 75 Pa (Correct answer)
- 0.40 cfm/ft² at 75 Pa
- 0.50 cfm/ft² at 75 Pa
- 1.0 cfm/ft² at 75 Pa
Correct answer: 0.25 cfm/ft² at 75 Pa
IECC 2021 requires commercial buildings to achieve an air leakage rate no greater than 0.25 cfm/ft² at a pressure differential of 75 Pa.
Question 2: Which ICC certification specifically covers energy inspection in residential construction projects?
- Residential Energy Inspector/Plans Examiner (REIPE) (Correct answer)
- Commercial Energy Plans Examiner (CEPE)
- Green Building Inspector (GBI)
- Building Energy Auditor (BEA)
Correct answer: Residential Energy Inspector/Plans Examiner (REIPE)
The ICC Residential Energy Inspector/Plans Examiner (REIPE) credential covers energy code compliance for residential construction.
Question 3: In ASHRAE 90.1, what is the primary method used to establish a baseline building model for the Energy Cost Budget path?
- Appendix G Performance Rating Method (Correct answer)
- Table 5.5 prescriptive envelope values
- Section 6 HVAC prescriptive requirements
- Section 9 lighting power allowances
Correct answer: Appendix G Performance Rating Method
Appendix G of ASHRAE 90.1 defines the Performance Rating Method and provides the baseline building model rules for the Energy Cost Budget compliance path.
Question 4: A building's solar heat gain coefficient (SHGC) requirement is MOST directly related to which climate characteristic?
- Annual cooling degree days (Correct answer)
- Annual heating degree days
- Annual precipitation totals
- Altitude above sea level
Correct answer: Annual cooling degree days
SHGC limits are driven primarily by cooling load potential, which correlates with annual cooling degree days in a given climate zone.
Question 5: Which section of the IECC addresses the commissioning requirements for commercial mechanical systems?
- Section C408 (Correct answer)
- Section C303
- Section C401
- Section C502
Correct answer: Section C408
IECC Section C408 outlines the systems commissioning and completion requirements for commercial HVAC, lighting, and other mechanical systems.
Question 6: When performing a whole-building energy simulation, which software tool is listed in ASHRAE 90.1 Appendix G as an approved simulation program?
- EnergyPlus (Correct answer)
- SketchUp
- AutoCAD MEP
- Revit MEP
Correct answer: EnergyPlus
EnergyPlus is one of the DOE-validated whole-building energy simulation programs approved for use under ASHRAE 90.1 Appendix G compliance.
Question 7: Under the IECC 2021 residential provisions, the maximum fenestration U-factor for Climate Zone 5 is:
- 0.30 (Correct answer)
- 0.35
- 0.40
- 0.45
Correct answer: 0.30
IECC 2021 Table R402.1.2 specifies a maximum fenestration U-factor of 0.30 for Climate Zone 5 residential buildings.
