Passive Solar Heating And Energy Efficiency

Most of us don’t live in Southern California where they have climate instead of weather. Because of that our winter heating costs can be astronomical. Who doesn’t want to save energy and money? You get the cachet of energy efficiency in these green-conscious times and you save a little extra money to use however you want. One thing people seldom consider when it comes to alternative home heating is the use of passive solar heating.

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?

Now we have the Trombe wall. It is made of some sort of material (concrete or rock, for instance) which is utilized because of its thermal mass. This means that it holds in the heat of the warmest part of the daytime and releases it gradually throughout the following hours. It has exterior insulation by means of a sheet of glass and also has an airspace which means it avoids losing warmth during the nighttime. Over the glass there is a shade which lets the lower wintertime sunshine in but keeps the higher summertime sunshine out. That results in smaller air conditioning costs also.

Unless you are doing major renovations to your home, it may not be easy to retrofit your house for passive solar heating. However designing a custom home is very expensive, and so is implementing other energy efficient measures, such as radiant heating. The advantage of passive solar is that once installed, it costs almost nothing to use as opposed to the other alternatives.

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.

Ideas that circulate in the mainstream today do work, but people have been looking for money saving opportunities for a long time now. It’s due now to the increase in environmental consciousness and rise in heating costs that is leading people to look to the solutions of yesteryear, such as passive solar heating, that were used effectively by our ancestors to save resources, to use as solutions to help save the world.

Our winter heating costs can be astronomical. Who doesn’t want to save energy and money? You get the cachet of energy efficiency in these green-conscious times and you save a little extra money to use however you want. One thing people seldom consider when it comes to alternative home heating is the effect of passive solar heating. 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.
