Re: [EnergyPlus_Support] Phase Change Materials



Dear Joe, 

I am not sure about PCM's as an open studio measure, however if you export to IDF then it is pretty straightforward to add a material with the PCM material properties and a material property phase change object and an object that calls the conduction finite difference algorithm.  In previous work I setup and ran models for thousands of buildings at many locations and found: PCM's are most beneficial in terms of sensible cooling load reduction, operative temperature stabilization for comfort enhancement, and HVAC energy savings in thermal zones that have high daytime heat gains and high nighttime heat losses. 

If you have issues setting up your model or interpreting results and post them here I will be happy to help.

Best of regards-

Good afternoon,

I am trying to add phase changing materials to the building fabric of my OpenStudio model for my university dissertation.

OpenStudio does not deal with PCMs currently, so the only way of implementing them into my model is through an EnergyPlus measure.

There are guides for writing measures online, but these are limited to generic measures which do not have the inclusion of PCMs (as far as I am aware).

Do you have any template measures which contain PCMs? Or failing that, do you have any guides on how to write a measure which includes PCMs?

Thanks & Regards,
Joe
