The Internet portal Agroklub conducted an interview with academician Veljko Milković on the occasion of his concept of reflective surfaces applied in agricultural production. Stables and barns can be built on a similar principle as self-heating eco-houses, because in fact a more favorable temperature provides higher productivity in food production, says Milković.

The original article is published in Serbian language, so the follownig text is a full translation of the published article:

Thanks to the Novi Sad inventor and academician of SAIN (Serbian Academy of Inventors and Scientists), Veljko Milković, in Serbia for nearly three decades there are a dozen self-heating ecological houses or solar dugouts that have proven to be an excellent investment thanks to reflective panels that can be used in agriculture.

This type of construction pays off in ten years at the longest, so the house literally pays off on its own, because these are constructions with reflective surfaces, which have shown that they can save up to 85% on heating. Also, those who live in them, state that about 30% is saved on lighting.

The reason for that is that instead of an ordinary roof, they have earth protection, which protects the house from low temperatures during the winter, but also high ones during the summer months. Another advantage is that the walls are also protected from erosion, so the solar eco-dugout requires the least investment with which the greatest energy savings are obtained.

The creator of the idea of a self-heating ecological house states that this type of building does not require deep foundations, neither a storage room for heating, nor the large consumers such as boilers for steam heating, radiators and stoves.

The key is that its foundations are buried about a meter into the ground. However, the interlocutor points out that construction is not possible in all parts of the country due to groundwater. Wavy terrain is good for its construction, but it also proved to be excellent in the plains.

In fact, the wisdom is that the savings in heating are based on surfaces, which mostly reflect direct and diffuse radiation from the sun. It is a glossy coating, aluminum foil and sheets on a solid surface. It is allowed for the foil to be milky white, as there are no large losses due to diffusion, and it is placed directly next to the window.

Reflective panels in agricultural buildings as well

All of the above can be applied in agriculture as well, because this principle is especially interesting in the breeding of all types of domestic animals. Stables and barns can be built on a similar principle as self-heating eco-houses, because in fact a more favorable temperature enables higher productivity in food production. Facilities with soil protection can be adapted for breeding all types of domestic and other species of animals.

Due to faster growth and maturation of plants, the permeability effect can be installed in a greenhouse or hothouse, and in addition to growing certain agricultural crops, a similar principle can be used for growing mushrooms, desalination of sea water or distillation of polluted water. "These panels are excellent in dryers, pantries and food warehouses, but also in wineries. All this is feasible according to the concept of self-heating," he concluded.

In November 2002, he received his highest recognition - the November Charter of the City of Novi Sad for the eco - house project, as well as for his outstanding contribution to innovations in the field of ecology and energy. Later in 2009, he received recognition for one of the nine best technological innovations in Serbia. Then follows the International Sustainability Award "Energy Globe Award 2010", when this invention became the national winner for the Republic of Serbia for 2010.
