 |
|
The CLG conventions state that we are no longer able to use the software default values for the flow rate (l/s/m2) of local mechanical extracts but instead must use the values in the prescribed list.
Are you able to offer any guidance on how to calculate air changes per hour into l/s/m2 please?
I appreciate any assistance you are able to offer. |

In the conventions guide released earlier this year there is an appendix at the end for air changes per hour. use this as a reference (or CIBSE Guide)
calculate the volume of your zone
multiply by air changes per hour
divide air changes per hour (in l/s) by the floor area. |
