I am an MSc student in Cardiff University and I am now starting my dissertation on the use of water in the envelope of a building, in order to regulate heat flows. I am new to TRNSYS and I would like to know if the following is possible and to get some direction/guidance regarding these areas:

1) Can water as a construction material on the enveope of a building be modelled in TRNSYS?
2) Can water flows (due to natural, or forced circulation, or from solar heating) inside pipes embedded on the fabric of a building be modelled?
3) In the case i can simulate a natural flow or circulation of water in a chamber, then at which moments? under which circumstances? I reckon that even with a stable incident solar radiation, the temperature of the water will be different after 10 minutes, 30 minutes 1 hour, or 12 hours. Can i calculate or simulate this interaction of the incident solar radiation on the water chamber and its effect on the natural flow of the it?
4) Considering a pipework or a network of chambers that contain water and supposing that some of them are exposed to solar radiation whereas others are in shade, provided that there is a natural flow of water caused by the differentiation in temperature, could i simulate somehow the heat distribution in the fluid? could the constant differentiation in temperature and flow of the water in this network be somehow calculated?
5) In the above case could i have different time "snapshots" of the system? To get an idea how this mechanism behaves?
6) In the case that these water chambers-containers form an enclosure, would i be able to simulate the conditions in this enclosure caused by the presence and flow of water around it?
