Savings in heating is based on reflecting surfaces i.e. surfaces that reflect direct and diffuse radiation of the Sun (around 80%). These are glossy coats (of lacquer and paint), aluminium foils and metal sheets on hard surface. You can also use milk-white paint, which is also acceptable since there is not much diffusion loss because the reflecting surfaces are positioned next to the window.
Special attention should be paid to reflecting surfaces, since they are the cheapest solar device which, in addition to heating, also increases the presence of light within the object.
Glossy foils, metal sheets and coats on hard surface can be positioned on upper or lower part of the house. Upper reflecting surface is fixed and built into the eaves, and the lower one is movable and can be used as a shutter.
Reflecting surfaces are the cheapest solar device which, in addition to heating, also increases the presence of light within the object. Eco house in Novi Sad (Serbia), for example, had savings in lightning of 30%.
Objects with soil protection and/or reflecting surfaces are especially acceptable for breeding of all farm animals, and many savings in food production are enabled with the rise in temperature of the ledge. The concept of self-heating eco-houses can also be applied in constructing stables, thus enabling more appropriate temperatures and insuring higher productivity in food production. It is possible to adjust the objects with soil protection completely to breeding of all kinds of farm and other animals and to provide free (solar) heating of stables with the help of reflecting surfaces.
Application: agricultural eco-buildings - eco stables for small and large animals; small farms intended for breeding poultry, rabbits, bees; mushroom farms; Californian worms farms; greenhouses and hothouses with reflective surfaces; driers, pantries, warehouses for food; complete farms and agricultural holdings with objects made using the concept of self-heating eco-house; wineries with the use of reflective surfaces etc.
