Saving Energy in an OR
Saving Energy in an OR
(OP)
I am currently working with a hospital to lower there energy usage. One way that was brought up was to lower the air chages when the day operating room is not in use over the night time. I know the standard is 15 ACH when it is in use, but does that need to be maintained even if it is shut down? If anybody else as done research on the subject or knows where to find the information I am looking for I would be grateful.

Is this operating room served with energy recovery ventilator??
Does this AHU have the control valve to vary the flow of chilled/hot water??
savings can be done....some save by dollars.... others save even the cents...

Would make sense to have a general mode with low ACH, OR mode with high ACH, and an off mode. But confirm with the authorities this is acceptable.

Most ORs use 15~20 ACHPH and that is adequate for a recovery time( time required to bring the room upto required cleanliness level) of less than 30 minutes if terminal HEPA filters are used.

DOH requires 20 ach, but does not state that I can remember that you can have an "off" period. The only time I have seen that apply is when you perform a daily fire alarm pull test (FDNY requirement) and all fans over 2000cfm must shut down. I will check the codes when I go back in this week.
