Correct Answer: B
Extending occupancy hours (Option B) increases energy consumption and, in turn, a facility's carbon footprint.
Why Option B is Correct?
* Longer operational hours mean increased use of HVAC, lighting, and electrical systems, leading to higher energy consumption and greater carbon emissions.
* IFMA's Environmental Stewardship & Sustainability competency emphasizes the importance of energy efficiency in reducing carbon footprints.
Why Other Options Are Incorrect?
* Option A (Replacing filters in air handlers): Improving air filtration enhances HVAC efficiency and reduces energy waste, thereby lowering carbon emissions.
* Option C (Replacing the existing system with high-efficiency equipment): High-efficiency systems reduce energy consumption and emissions, decreasing the carbon footprint.
