When it comes to heating costs, most of us are not lucky enough to live in a temperate area with a constant year-round climate, and instead have to contend with winter heating bills that can be exceptionally high. When evaluating alternative home heating, an option that is often overlooked is passive solar heating. You not only save money, but energy as well.

Even on the coldest winter days, the sun's heat can be significant. It's only the shortness of the days that keeps the snows from melting. What if you could harness that heating power, even for the short time you get it, without making huge changes to the structure of your home?

Enter the Trombe wall. It's a wall of material used for thermal mass (concrete or stone, for example) to store the heat of the day and release it slowly through the day and night. It's insulated on the outside by a pane of glass and an airspace to prevent heat loss to outside at night. Above the glass is a shade that allows direct exposure to the low winter sun, but shades the glass from the prolonged heat of the high summer sun, helping to keep summer cooling bills low as well.

Many of us are interested in pursuing more energy efficient heating alternatives such as passive solar heating. Whatever alternative you choose the cost of installation may be expensive. Whether you are seeking a custom designed home or renovating an existing structure you have options. One advantage of passive solar heating is that once installed continued use expenses are nominal.

Not everything from the past involves excessive waste of resources. Trombe walls invented in the 19th century are an excellent green choice for building or buying your new home. These type of walls, made popular in home designs in the 1960's, are to be considered when you are searching for an energy efficient home.

Now that the awareness of green issues is commonplace, people are becoming aware of the costs involved in heating our homes, both financial and environmental. Ideas from our ancestors, both ancient and not so ancient, solutions such as passive solar heating, are being looked at as viable because not only do they have a benefit environmentally, but they save us money as well.
