How does ASHRAE 62.1 view energy efficiency in relation to IAQ?

How does ASHRAE 62.1 view energy efficiency in relation to IAQ?

• A. Energy efficiency must be sacrificed to achieve IAQ.
• B. Energy efficiency and IAQ are incompatible.
• C. It allows energy-efficient strategies like filtration and recirculation as long as IAQ targets are met.
• D. It prohibits any energy-saving measures.

Answer: (C)

Energy efficiency and IAQ are not at odds in ASHRAE 62.1. The standard allows energy-saving approaches as long as IAQ targets are still met. For example, you can use filtration and recirculation to improve IAQ and reduce outdoor-air requirements without compromising IAQ, and you can employ demand-controlled ventilation to reduce outdoor air during low occupancy while staying within IAQ targets. Energy recovery helps precondition outdoor air so you save energy while maintaining IAQ. In short, energy-efficient strategies are permitted and encouraged, provided they are designed, installed, and operated to meet the IAQ criteria established by the standard.
