| hi! im working on my thesis ryt now..my proposal is "the study of water wall as a thermal mass for the interior and exterior walls of a science center". im asking 4 views about topics involving water walls as a thermal mass. |

I remember an experimental villa in Almere (NL) at the end of the 1980's: it used an enormous tank of water (something like 60 m3) to accumulate heat during summer and releasing it during winter. Apparently this direct approach didn't work very well, the house was demolished after only two years.
Nowadays more often heat pumps are used. they store warmed up water 40 m underground, pumping it up in the winter. |

Another option is to use water columns or tubes. The tubes can be filled with water that then radiates solar collected heat. The columns can be made of lined steel, plastic, or any other material suitable for containing it. The can be part of the structure, or they can be independent of the structure.
There was a building constructed in the 1970's or 1980's using clear plastic columns. I can't recall where it was built. I have no details about the efficiency of this approach. If my memory is correct these columns were placed behind a glass wall to collect solar energy. Water columns or water storage tanks lend themselves to the direct collection of solar energy. One major consideration is the extra upfront costs of providing for thermal storage. |
