HVAC Ducting and component layout design rules with revit in mind

[Mark B]

Hi
Does anyone have some basic rules for HVAC design and layout with REVIT in mind?
Um, like number of diffusers and extractors per cubic meter.
Something like a "HVAC manual for newbies" or some links to explore?
Cheers

Order the Trane HVAC design manual..worth a ton of HVAC design gold.
