Does anyone know of approved methods to prove this credit without completing a full energy model to simulate indoor conditions, in particular radiant heat?
It seems a Psychrometric chart is no longer acceptable.
We have a DC fan coil unit system with VSD control in climate Zone 2A (Warm/Humid)
Our reviewer is asking for us to provide documentation, such as PMV/PPD calculations or ASHRAE comfort tool results, demonstrating how the thermal comfort conditions have been established for the project and how the design of the conditioning system addresses the thermal comfort design with air speeds greater than 40 feet per minute.
We can do this if we run a full energy model but as it is a small LEED-CI project following prescritpive approach we are not doing modelling.
