Hi, I am also trying to simulate PCMs in a building envelope for my dissertation. I have incorporated the enthalpy curve and wall material into a EPlus reference building and have gotten results that I am not comfortable with. I looked at the EPlus PCM example idf but itis not representative of what I am doing. I would like to review and run the Solar Decathlon idf to see what that output looks like with and without PCM. However, I could not download your attachment from the group messages.
Thanks,
