Operative temperature in a house with Solar Floor heating and PCM in floor

[<bengt.perers@xxxxxxxxxxxxxxxxxxxxxxxx>]

I just wanted to ask if anybody already has done some work on Solar floor
heating (pipe system in floor) including PCM (latent heat) materials in the
floor. 

Our main question now is to investigate how much the operative temperature
(as felt by a human) is affected due to the large variations in solar input
day by day.

Before starting to programme or modify a house model in TRNSYS with PCM
option included, I wanted to check if that may already be available 
somewhere.
