NC-2009 EAp2: Minimum Energy Performance
I use Carrier-HAP and according to ASHRAE 90.1 G.1 #4, all baseline HVAC fans should be running continuously when the space is occupied and cycled when the space is unoccupied. However, I have some systems that follow exception (a). Any hint how to apply this?

A HAP subscription comes with customer service included so you can call/email them directly. There is also a HAP Users discussion forum at onebuilding.org.
If it is for a heating only space model a system 9 or 10 from ASHRAE 90.1-2010 which is allowed via addendum dn. Another way way to deal with the no heating/no cooling system situation is to set the temperatures in the spaces so that the system never comes on in the first place. There are ways around the situation of not having a heating or cooling system in a space.
