Question

Identify when the insufficient ventilation warning will appear in the Homeowner Information Sheet.

a) When the insulation level is too high
b) When the heating system is too efficient
c) When the air exchange rate is insufficient
d) When the windows are not properly sealed

Answer 1

The insufficient ventilation warning will appear in the Homeowner Information Sheet when the air exchange rate is insufficient. Insufficient ventilation can lead to an increase in pollutant levels and can have negative impacts on indoor air quality.

Step-by-step explanation:

The insufficient ventilation warning will appear in the Homeowner Information Sheet when the air exchange rate is insufficient. When there is little infiltration, natural ventilation, or mechanical ventilation, the air exchange rate is low and pollutant levels can increase. Insufficient ventilation can lead to an increase in pollutant levels and can have negative impacts on indoor air quality. If the air exchange rate is too low, it can be indicated in the Homeowner Information Sheet to prompt corrective actions for better ventilation.
