Wine Cellar without cooling system - possible?
I'm building a new house in Northern California and we will be including a wine cellar. It will be in the basement, which will eventually be climate controlled (at first it will be unfinished).
At the moment we have complete control over size, insulation and placement of the cellar so I'm looking for some overall planning advice. Also, I'm wondering if it is possible, with the right insulation, to build it in such a way that we do not require a cooling unit?
It will be completly subterrarian (one emergency exit window in entire 30x30ish basement) and if it is worthwhile i could plan it with three exterior walls.
Any initial planning suggestions?
Also, I should mention that we will be doing this as a mostly DIY project after the house is completed so I'm just trying to make sure we hav
