Build a Wine Cellar to Help the Environment

by Basement Wine Cellar Guy on February 22, 2010

You want to build a basement wine cellar for the convenience, but you are reluctant to build it because it seems like an extravagance. Guess what: a home wine cellar is actually a green alternative! That’s right: building a basement wine cellar helps the environment!

Refrigerator Wine Coolers

Before I built my wine cellar, I had two wine coolers, or refrigerators. The motor to cool the units ran virtually none stop, just like happens with your kitchen refrigerator. Obviously they were using a lot of energy.

With my basement wine cellar cooling unit, the unit only runs for perhaps five minutes every hour, often less. Obviously one small unit running for five minutes per hour uses less energy than two refrigerators running none stop. Even better, my wine cellar can hold 1,200 bottles, as compared to under 300 for more two wine fridges. That’s an obvious energy saving.

Why the difference? I’m not an engineer, but I assume it’s due to the fact that, once the wine cellar reaches the optimal temperature, the 1,000 bottles store the coolness, which keeps the cellar cool. Also, the wine cellar has far better insulation than a wine refrigerator, which helps to maintain the temperature.

Other than great insulation, and keeping the door closed, I have two other energy saving tips.

First, keep your wine cellar full. The more wine you have, the more mass you have to retain the temperature. If you can’t fill your wine cellar with wine, store pop, beer, vegetables or anything else to help retain the heat.

Second, during the coldest days of winter, half fill plastic jugs with water, and leave them outside overnight to freeze. Then, bring them into your wine cellar during the day. They will absorb heat while they cool, which saves energy. In effect you are bringing the cold air from outside into your wine cellar. That’s free air conditioning, and that’s using winter to your advantage.

Wine Cellar Floor Insulation

by Basement Wine Cellar Guy on March 20, 2009

In my last post I discussed spray foam insulation in the walls and ceiling. The same technique was used for the floor. Here’s what the floor looked like after framing but before the insulation was applied:

Framing Wine Cellar Floor

Here’s the floor after applying the insulation:

Floor Insulation

Yes, it looks just like the walls look. The foam insulation does dry solid, but it is full of tiny air pockets, so you don’t want to walk on it, since you will likely compress the air pockets and lower the insulation value. That’s why we applied the plywood floor as soon as possible:

Yes, this picture also shows the drywall on the walls, but that’s the subject of my next post.

Spray Foam Insulation

Now that the framing is done, it’s time for the insulation. Insulation is critical, since the goal is to maintain a constant temperature in the basement wine cellar. The better the insulation, the less variation in temperature, and therefore the less effort required by the cooling unit to keep the wine cellar at a constant [...]
