[QUOTE="Baluncore, post: 6242852, member: 447632"] To answer the question you will need to evaluate what possible passive cooling systems can be integrated into the construction. Keep the sun off the surface, so you have a surface at the air temperature. The temperature below the surface will be the average air temperature, with less variation as you go deeper. But if you go to ridiculous depths you will encounter the Earth's “geothermal gradient” increasing at about 1°F per 60 feet downwards. It is easy to maintain the average external air temperature in a building. Passive cooling below that average is possible. During dry hot months you might use some evaporative cooling, which costs water. You could cover the cellar with a layer of vertical tubes, open at the top, that fill with cool air at night, venting heat which biasing the average cellar roof temperature downwards. Insulate the walls. If you need an active cooling system, it may only need to operate during the day, operated on solar power. Take warm air from the vault of the cellar where it will accumulates, introduce cool air at the base. Store the wine in the cooler air close to the floor. [/QUOTE]
