Part L 2013 - Increased SFP in Notional Building due to HEPA filters
Posted: Fri Jan 29, 2016 1:10 pm
In the recent update to the 2013 NCM Modelling Guide there was a note stating that if a room required the use of a HEPA filter, then the system assigned to the room in the Notional Building would have its SFP increased by 1 W/l/s.
This was implemented for Part L2 2013 - ApacheSim method in VE 2015 Feature Pack 2. A few users have asked how this is applied through the software, so I have listed the steps below showing what you have to do.
Go to a room using a system with a HEPA Filter, and on the Building Regulations tab select “High pressure air drop treatment”.
When you do this a new Notional Building System is created and it is labelled (HEPA). This will have its SFP increased by 1 W/l/s.
This system is now used by the Notional Building.
