A project team is discussing increasing the ventilation of a planned building in an urban area with poor outside air quality. The building will be mechanically ventilated. What can be done to minimize additional energy consumption?
A: Increase airflow paths
B: Alter external driving pressures
C: Use heat recovery
D: Increase outdoor air intakes

参考答案: C

Reference: Indoor Environmental Quality Credit, Increased Ventilation, Benefits, Economic Issues

Higher ventilation rates can improve indoor air quality, but can also increase costs. Mechanically ventilated spaces can use heat recovery to minimize these extra costs.

For a description of a heat recovery ventilator see this Popular Mechanics article. This system is one for a home but the same kind of system applies.
