LEED Green Associate (LEED GA) — Question 2

In which of the following common building applications are chlorofluorocarbons (CFCs) found?

Answer options

• A. Fire hydrants
• B. Roof-top vents
• C. Insulation agents
• D. Centrifugal chillers

Correct answer: C

Explanation

CFCs are commonly used in insulation agents due to their properties as effective refrigerants and foaming agents. The other options, such as fire hydrants and roof-top vents, do not typically involve CFCs in their construction or function, while centrifugal chillers may use CFCs but are not classified as building applications in the same way as insulation.
