In NSPIRE practice, which temperature range is classified as severe?

• A. Between 60 and 63.9 degrees
• B. Between 68 and 72 degrees
• C. Between 64 and 67.9 degrees
• D. Between 58 and 59.9 degrees

Answer: (C)

NSPIRE uses severity bands for indoor temperature to signal when conditions may require action. The band defined as severe covers 64.0 to 67.9 degrees Fahrenheit. This range is flagged as severe because it indicates underheating that can affect occupant comfort and safety, suggesting the heating system isn’t delivering adequate heat. It sits between the cooler ranges (which indicate more extreme underheating) and the warmer range (which, while outside the comfort zone, isn’t classified as severe in this scheme). So, the 64–67.9°F range is the one designated as severe in NSPIRE practice.
