A passive solar house… what is it exactly? Well, there are two main types of solar power; active and passive. Active utilizes the power of photovoltaic cells, wafers of layered P-type and N-type silicon which transform the energy of the photons from the sunlight’s rays falling onto the cells into flowing electrons of electricity. Passive solar power is a bit different – instead of extracting energy solely from the sun’s light, it does so primarily from the sun’s heat, but in some ways from the light as well. How is this done? Allow me to explain…
In a passive solar house, heat from the sun is taken and/or stored for providing heat – whether heat for heating the air and circulating it, or for hot water. Perhaps the simplest form of passive solar energy at work is when sunlight pours through the windows. With the way modern windows are today, double (or even triple) paned, vacuum or special gas impregnated, as well as completely insulated, they’re actually dynamic heat magnifiers. This can have a profound effect on the warmth of the house on really sunny days. In northern areas, another very simple idea is merely to have the house’s exterior be of a very dark color. However, there are other means of using passive energy from the sun that are less simple.Visit here: Insulation4Us.com
Sometimes a passive solar house can be heated and provided with hot water through the means of large cylinders of clear plastic, filled with water, with about half of the inner face of the tube’s wall being colored a very dark color, even black. The sunlight (and heat) pours in, is more absorbed by the darker inner surface, heats it up as a result, which in turn heats the water, and the water is then circulated throughout the home to provide heating for the rooms within, or this also may be utilized as a means of acquiring hot water for use in cooking, cleaning and etc. This type of energy conservation efficiency is just what many are looking for when seeking to build a passive solar house.
Some passive solar house designs include the concept of a solar furnace in order to heat the house with it. These are basically collectors and focusers of the sun’s light and heat, and through convection ventilation the air is circulated within and throughout the entire house to provide warmth and heat for the home. This heat too, can be directed for the purpose of heating water stored away as a hot water source. With a passive solar house built with this type of system in mind, you can be sure that the utility bills for just such a place can be exceedingly low in cost. While we lessen our impact on the environment we are also lessening the impact in our wallets.
