DIY heating passive solar
Do it yourself, diy heating passive solar is a smart step for any homeowner who wants to limit their use of electricity.
Proper use of passive solar for heating a home can reduce energy consumption by 30%!
Homes designed with this in mind are very rare. The location and orientation of a structure are the first most important step in a highly efficient home. Most people can make some use of passive solar even if the home is not perfectly located.
diy heating passive solarIn the northern hemisphere you will maximize your solar capacity by orienting the house to the south, the optimal orientation is perpendicular to the high point of the sun on the winter solstice. This maximizes your sun capacity on the shortest day of the year, and guarantees maximum capacity over the course of the year.
A sun room on this side of the house acts as a regulation chamber, it is a void space which is used to trap the heat (regulated by blinds). As much as possible the windows in this sun room should be angled so they receive the maximum sun.
that trapped heat can be radiated throughout the house at night when the temperature drops, or alternatively, the trapped heat can be quickly released by strategically placed open windows, skylights, or using a chimney maximize the circulation of air. The engineering necessary for smart passive solar heating is relatively simple once you recognize the importance.
Mass (e.g. a wall) absorbs heat when the sun is out. Mass radiates or releases this heat when the sun goes down and the temperature drops. This warmth can be used to heat bedrooms at night. Therefore, it is nice to have bedrooms near the south side of the house or, in the best case, adjoining your sun room.
To help regulate temperatures it is important to remember that the frost line is usually 4 to 5 feet below the surface and maintains a temperature 58 degrees year-round. By digging out a basement you can take advantage of this fact and have a cool room in the heat and a warmer room when it's cold.
It's easier to heat a room that begins at 58 degrees than an upstairs room that drop much lower in freezing temperatures.
Another important fact to remember for diy heating passive solar enthusiasts is that most heat is lost through the roof. Insulating your roof is absolutely crucial to maintaining heat in your home. Next important are windows and doors. Single pane windows lose an incredible amount of energy. Energy efficient windows are important to insulating your home. Energy efficiency improvements like this can reduce your heating bills by 50% in many cases.
