# DOMAIN 1: ENERGY POLICIES, CODES, AND STANDARDS
## Questions 1-35
**QUESTION 1**
A facility manager is planning a major HVAC retrofit for a 150,000 sq ft office building
constructed in 2008. Which standard provides the most relevant guidance for energy efficiency
requirements for this project?
A) ASHRAE Standard 62.1
B) ASHRAE Standard 90.1
C) ASHRAE Standard 55
D) ASHRAE Standard 100
**CORRECT ANSWER: B**
,Page 2 of 304
**Rationale:** ASHRAE Standard 90.1 provides minimum energy efficiency requirements for
building design, construction, and operation, including HVAC systems. For a retrofit project, this
standard establishes the baseline for energy-efficient design. The 2022 version (current for 2026-
2027) includes updates for HVAC efficiency, controls, and commissioning .
**Why the others are incorrect:**
- **A) ASHRAE Standard 62.1:** This standard addresses ventilation for acceptable indoor air
quality, not energy efficiency requirements. While important for HVAC design, it does not
establish energy performance criteria .
- **C) ASHRAE Standard 55:** This covers thermal environmental conditions for human
occupancy, defining comfort parameters rather than energy efficiency requirements.
- **D) ASHRAE Standard 100:** This standard focuses on energy conservation in existing
buildings through operational and maintenance practices, but is not the primary standard for new
construction or major retrofit design requirements.

**QUESTION 2**
Which of the following is a key requirement of the Energy Policy Act (EPAct) of 2005 for
federal facilities?
A) All federal buildings must achieve LEED Platinum certification
B) Federal facilities must reduce energy intensity by 30% from 2003 baseline by 2015
C) All federal buildings must be powered entirely by renewable energy
D) Federal agencies must conduct energy audits every 10 years
**CORRECT ANSWER: B**
,Page 3 of 304
**Rationale:** EPAct 2005 established energy intensity reduction targets for federal facilities,
requiring a 30% reduction from the 2003 baseline by 2015. This was part of the federal
government's energy management requirements . The act also established other requirements
including metering, commissioning, and energy audits, but the 30% reduction target was a key
performance metric.
**Why the others are incorrect:**
- **A) LEED Platinum certification:** EPAct 2005 required LEED Silver certification or
equivalent for new federal buildings, not Platinum. The requirement has since been updated, but
Platinum was never mandated.
- **C) All renewable energy:** EPAct 2005 did not require all federal buildings to be powered
by renewable energy. It did encourage renewable energy use and set some targets, but 100%
renewable was not mandated.
- **D) Energy audits every 10 years:** EPAct requires energy audits every 4 years for federal
facilities, not 10 years. The 4-year cycle was established to ensure regular evaluation of energy
performance .

**QUESTION 3**
An organization is implementing an ISO 50001 energy management system. What is the primary
benefit of achieving ISO 50001 certification?
A) It guarantees 50% energy cost reduction within the first year
B) It provides a systematic framework for continuous energy performance improvement
C) It eliminates the need for energy audits
D) It qualifies the organization for automatic tax credits
**CORRECT ANSWER: B**
, Page 4 of 304
**Rationale:** ISO 50001 provides a structured framework for establishing, implementing,
maintaining, and improving an energy management system. The standard follows the Plan-Do-
Check-Act (PDCA) cycle to drive continuous improvement in energy performance. It helps
organizations systematically manage energy use rather than providing one-time savings
guarantees .
**Why the others are incorrect:**
- **A) 50% cost reduction guarantee:** ISO 50001 does not guarantee specific savings
percentages. Savings depend on the organization's baseline, opportunities, and implementation
efforts. Continuous improvement is the goal, not a fixed reduction target.
- **C) Eliminates need for energy audits:** ISO 50001 actually includes requirements for energy
reviews and auditing. It does not eliminate these activities but integrates them into a management
system.
- **D) Automatic tax credits:** While ISO 50001 certification may help qualify for some
incentive programs, it does not automatically generate tax credits. Tax benefits depend on
specific government programs and regional regulations.

**QUESTION 4**
Which of the following is NOT a required component of an ASHRAE Level II energy audit?
A) Utility bill analysis
B) Building envelope inspection
C) Sub-metering of specific systems
D) Computer simulation of energy savings for all ECMs
