Building with improper insulation levels could contribute to which outcome?

Building with improper insulation levels could contribute to which outcome?

• A. Increased fuel costs for the building.
• B. Improved energy efficiency.
• C. No effect on energy bills.
• D. Reduced heat loss in winter.

Answer: (A)

Insulation slows heat transfer. When insulation levels are improper, heat escapes from the building in winter, causing the heating system to run longer and work harder to keep the indoor temperature steady. That extra running time uses more fuel, driving up the building’s fuel costs. The other options don’t fit because improper insulation does not improve energy efficiency, does affect energy bills (it increases them), and does not reduce heat loss—in fact, it increases heat loss.
