Passive solar energy for home heating

The use of passive solar has gained enormous fame as a result of its practicality. This inexpensive method of heating homes is free forever once the initial investment is made into producing the system. It is no wonder this method is so popular.

The use of passive solar in homes within cold regions is effective to a certain extent. There is some rationale that is required regarding the time your area receives sunlight. This method would not be productive for areas receiving direct sunlight for less than five hours. Sufficient sunlight is needed to produce the required energy to heat your home.

Regions with warm to mild climates are the areas where passive solar would be most effective. The popularity is well earned, as passive solar offers a means to keep homes warm for free after that initial installation investment. Regions that receive a lot of sunlight simply have to strategize the location of large windows. If you already are living in a built home, you may look into altering the positioning of windows and if you are in the process of building, make sure that you consult your architect to consider passive solar in the house design.

Two key elements to consider in the architectural design of your home include a greenhouse and the use of large Trombe Wall.

In the principle of passive solar design, Trombe Walls are very effective to harness the heat from the sun’s rays. The use of these walls could also be a wonderful aesthetic element for your home. Use an eight to twelve foot length of a Trombe wall at the area facing south on your property. You may have to look at a larger wall if your home is in a colder region.

To make this method more effective, a supporting system should also be incorporated. The surface of the glass of the windows could lose a lot of heat energy when the glass plate heats the walls. An air circulation method is the supporting system that is needed for passive solar heating. The hot air must be drawn to another area at the other side of the wall. An unneeded room or free space would do the job. One should time the circulation somewhat like a solar thermostat. The goal is to retain heat inside the walls.

The greenhouse will allow you to collect the heat and retain it inside during the day. The principle used for greenhouses for plants is the same as what is needed for homes. The climate may be unfavourable but the presence of sun provides the source for heat energy. The heat collected must be kept inside as this heat could escape through the glass or similar surfaces in the same manner it came in. Air must be blown around the house using timers when the desired temperature is achieved in an effort to retain it.

The use of biomass is also a good heating method and offers an alternative to passive solar heating. A lot of people utilize furnaces that burn corn and find it dependable. This is one of the cheapest methods of generating heat, second to passive solar.

Solar energy is probably the most attractive source of energy. It is renewable and causes no pollution to the environment. If not regulated however, the heat that it offers your home may be too much.

A lot of us are unaware of the fact that we already use passive solar as an energy source. Expensive solar panels are not required in this method, as you can garnish solar energy through your regular windows. The heat from the sun is transferred to your home’s interior thus warming up all the furnishings inside it. People who understand this concept make it a point to design their home and their interiors to maximize the use of passive solar.

Our sun is a source of powerful energy. There are a lot of opportunities brought forth by the sun’s energy and we need to explore all the possibilities to utilize this mass of power to it’s fullest potential. One thing we must remember is that this energy could at times be too much so while we learn about the application methods, we should also learn how to regulate it.

Passive solar heating is very effective and energy of the sun will surely bring heat. However, as the climate changes and summertime arrives, this heat could get unbearable.

When too much sun has penetrated into your home, the condition gets to be unfavourable. An effective way to prevent this is to use shading. There is a lot of sun shading devices that you could incorporate in your windows. Some of these can be installed in windows and some could be placed on open areas of the house like the porch. The best location is the exposed southern portion of your home where most of the sun is. You may opt to close all openings in this area during the day, and open it at night to let warm air enter.

There are other tricks to designing your home for passive solar. One is the use of the landscape that could utilize the elements outside the house. Plant trees around the house, ones that have lush leaves in the summer and lose these leaves in the winter. Placing trees in front of windows could regulate heat entering the house; they are like nature’s regulators to the passive solar system

Finally, the way to maintain an appropriate amount of heat for your home is to understand the nature of light and the sun. This level of understanding will help you maintain levels of temperature in you home at comfortable levels.
