Due to increased insulation, green structures enhance the potential of what?

• A. Settlement
• B. Flashover
• C. Shrinkage
• D. Moisture migration

Answer: (B)

Higher insulation keeps heat inside a space, so during a fire the heat builds up and stays trapped rather than escaping. This rapid heat buildup raises the temperature of everything in the room, increasing heat feedback to fuels and bringing the space to flashover—where all exposed surfaces ignite almost simultaneously. Green structures with more insulation therefore can raise the potential for flashover because heat is retained longer and spreads more quickly. Other concepts like settlement, shrinkage, or moisture migration aren’t about how heat behaves in a fire, so they don’t explain the fire growth dynamics at play here.
