In my experience, particularly in this economic environment, if the balancing cost $50, they would say it's $50 they don't want to spend.

AOP Forum Rules:
Here every commercial place that gets occupancy has to be tested and balanced. As a designer and a balancer, I would personally leave the OA setting alone. 10% may be a good rule of thumb, but I've done places that need 25%, and I've done stores that need 2% (co2 sensor setup). If 10% is to high, your causing excess energy usage, if you set it too low, you not allowing enough ventilation.
