Definition

The Air Diffusion Performance Index (ADPI) is used for cooling mode conditions. If several measurements of air velocity and air temperature are made throughout the occupied zone of a space, the ADPI is the percentage of locations where measurements were taken that meet the specifications for effective draft temperature and air velocity.

Description

Technical note: in IFC this property takes 'IfcReal' as value. Such objects are not included in bSDD for simplicity reason. IFC also doesn't enforce particular units, but recommends using metric SI units (metre, kilogram, etc.). Read the IFC documentation for more information.
