[papercreters] Re: Walk in cooler

How do you intend to actually cool it?

I know that basements can be kept at around 70 "or so", but above ground that'll take serious electricity. We're building a farmstand right now and I sure wish we could store fruit and veggie for sale.

It gets up to 110 here some days, and can be over 90 every day for six months at a time, sometimes humid, sometimes dry, sometimes thunder storms, and freezing maybe ten days a year. I started out thinking of using straw bale, but I'm concerned it would rot due to constant condensation in the bale wall. Then I thought earthbag, but apparently it's not very insulative unless you can fill it with volcanic scoria gravel which we do not have here. I'm going for a more eco friendly and cheaper option than shed with foam panels, so what do you think, is papercrete the thing to use? What is the optimal mix for insulating / structural walls?
