SFP Sustainable Facility Operations & Maintenance 3 — Questions and Answers
Question 1: A facility manager is developing a sustainable purchasing policy for office supplies. Which criterion should carry the most weight?
- Lowest unit purchase price
- Products made with post-consumer recycled content (Correct answer)
- Items sourced from international suppliers with lower labor costs
- Products packaged in the largest available sizes
Correct answer: Products made with post-consumer recycled content
Post-consumer recycled content reduces demand for virgin materials and diverts waste from landfills, directly supporting circular economy principles.
Question 2: Which commissioning activity is specific to existing buildings and focuses on improving current system performance?
- Initial commissioning (Cx)
- Retro-commissioning (RCx) (Correct answer)
- Re-commissioning
- Ongoing commissioning
Correct answer: Retro-commissioning (RCx)
Retro-commissioning (RCx) applies a systematic process to existing buildings that were not previously commissioned to optimize energy performance.
Question 3: A facility's irrigation system accounts for 40% of total water use. Which technology offers the greatest reduction potential?
- Drip irrigation for all landscape zones
- Weather-based evapotranspiration (ET) controllers (Correct answer)
- Soil moisture sensor-based irrigation scheduling
- Converting all turf to native drought-tolerant plants
Correct answer: Weather-based evapotranspiration (ET) controllers
ET-based controllers adjust irrigation schedules in real time based on actual evapotranspiration data, typically achieving the highest water savings across diverse landscape conditions.
Question 4: Under the EPA's Safer Choice program, which characteristic defines a Safer Choice-certified cleaning product?
- The product is manufactured in the United States
- All chemical ingredients meet EPA safety standards for human health and environment (Correct answer)
- The product contains at least 50% bio-based content
- The product is biodegradable within 28 days
Correct answer: All chemical ingredients meet EPA safety standards for human health and environment
EPA Safer Choice certification requires that every ingredient in a product meet strict standards for human health and environmental safety.
Question 5: When conducting a waste audit at a facility, the primary objective is to:
- Calculate the annual cost of waste disposal contracts
- Identify the composition and quantity of waste streams to prioritize diversion opportunities (Correct answer)
- Determine the weight of recyclables collected over the past year
- Assess compliance with local solid waste regulations
Correct answer: Identify the composition and quantity of waste streams to prioritize diversion opportunities
A waste audit characterizes waste by type and volume, enabling facility managers to identify which materials offer the greatest diversion and cost-reduction opportunities.
Question 6: Which indoor environmental quality parameter is most directly associated with occupant cognitive function and productivity, according to recent building science research?
- Relative humidity levels
- CO2 concentration as a proxy for ventilation adequacy (Correct answer)
- Illuminance levels on work surfaces
- Acoustic noise levels in open offices
Correct answer: CO2 concentration as a proxy for ventilation adequacy
Elevated CO2 concentrations in poorly ventilated spaces have been linked to measurable declines in cognitive performance and decision-making ability.
Question 7: A facility manager is evaluating solar photovoltaic (PV) installation. Which financial metric best captures the total lifetime economic value of the investment?
- Simple payback period
- Net Present Value (NPV) of lifetime energy savings (Correct answer)
- First-year return on investment
- Internal rate of return over a 5-year horizon
Correct answer: Net Present Value (NPV) of lifetime energy savings
NPV accounts for all future cash flows discounted to present value, providing the most comprehensive picture of a PV system's long-term economic benefit.
