LEED Green Associate Practice Test

What must the fundamental refrigerant management prerequisite ensure regarding CFC-based refrigerants?

1. They are preferable to renewable options

2. They are never used

3. They are reused continuously

4. They are documented for recycling

The correct answer is: They are never used

The fundamental refrigerant management prerequisite is designed to address the environmental impact of refrigerants, particularly those that contribute to ozone depletion and climate change. The correct answer is that CFC-based refrigerants must never be used. This approach stems from the established scientific consensus on the harmful effects of chlorofluorocarbons (CFCs) on the stratospheric ozone layer, which safeguards life on Earth from harmful ultraviolet radiation. By prohibiting the use of these substances, the prerequisite helps foster sustainable practices in building design and operation, aligning with broader goals of reducing greenhouse gas emissions and protecting natural resources. The other options do not accurately reflect the goals of the prerequisite. The notion of CFCs being preferable to renewable options contradicts the intentions of promoting environmentally friendly and sustainable refrigerants. Similarly, practices like reusing or documenting CFCs for recycling do not address the core issue of their harmfulness; instead, the focus is clearly on avoiding their use altogether to mitigate environmental damage.
