CHFM CHFM - Certified Healthcare Facility Manager Energy Management and Sustainability Questions and Answers 1 — Questions and Answers
Question 1: Which ASHRAE standard provides energy efficiency guidelines most commonly referenced for healthcare facilities in the US?
- ASHRAE 90.1 (Correct answer)
- ASHRAE 62.1
- ASHRAE 170
- ASHRAE 55
Correct answer: ASHRAE 90.1
ASHRAE 90.1 sets minimum energy efficiency requirements for buildings, including healthcare facilities, and is widely referenced in US codes.
Question 2: What term describes the ratio of useful cooling output to energy input for a chiller system?
- COP (Coefficient of Performance)
- EER (Energy Efficiency Ratio)
- SEER (Seasonal Energy Efficiency Ratio)
- kW/ton (Correct answer)
Correct answer: kW/ton
kW/ton is the standard performance metric for chillers in healthcare, representing kilowatts of power consumed per ton of cooling produced.
Question 3: A healthcare facility wants to reduce peak demand charges. Which strategy is MOST effective?
- Replacing all lighting with LEDs
- Load shifting using thermal energy storage (Correct answer)
- Installing submeters on every circuit
- Upgrading to high-efficiency boilers
Correct answer: Load shifting using thermal energy storage
Thermal energy storage allows cooling to be produced during off-peak hours and stored, directly reducing peak electrical demand charges.
Question 4: Under the EPA's ENERGY STAR Portfolio Manager, what score indicates a facility is in the top 25% of energy performance?
- Score of 50 or above
- Score of 75 or above (Correct answer)
- Score of 90 or above
- Score of 100
Correct answer: Score of 75 or above
An ENERGY STAR score of 75 or above qualifies a facility for ENERGY STAR certification, representing the top 25% of performance.
Question 5: Which federal law requires large federal facilities and encourages private healthcare facilities to report energy use and set reduction targets?
- Clean Air Act
- Energy Policy Act (EPAct) (Correct answer)
- National Environmental Policy Act
- Occupational Safety and Health Act
Correct answer: Energy Policy Act (EPAct)
The Energy Policy Act (EPAct) establishes energy efficiency standards and reporting requirements that influence healthcare facility energy programs.
Question 6: A building automation system (BAS) in a hospital is BEST used to:
- Replace preventive maintenance schedules
- Monitor and optimize HVAC, lighting, and utility systems centrally (Correct answer)
- Eliminate the need for certified operators
- Control medical gas pressures throughout the facility
Correct answer: Monitor and optimize HVAC, lighting, and utility systems centrally
A BAS centralizes control and monitoring of mechanical and electrical systems, enabling real-time optimization and energy savings.
