Eco houses in the area of Scandinavia have existed for a long time, while in recent years more and more are being built in Serbia.
An increasing number of buyers in Serbia are opting for the eco type of house, most often because they think it is profitable. Namely, according to experts, the energy consumed by eco houses is equal to that produced by the facility.
Veljko Kalicanin, the owner of the company that deals with the construction of eco-houses, shows that the price of a square meter of environmental facilities ranges from 280 euros and up.
Buyers often opt for a turnkey system, which is more expensive, but the important thing for them is that they can move into the house in just two months.
Gray construction costs less
The most common construction system comes from the area of Scandinavia, says the interlocutor.
– Future owners can opt for “gray construction” or construction on a turnkey basis, thus the price of houses varies. A square of gray construction costs 280 euros, while the system in which you get everything is almost 440 euros per square meter. Sometimes that price can be higher, and moving in can be up to two months in a month – says the owner of the company, Veljko Kalicanin.
The materials must be environmentally friendly, while wood predominates in construction, he says.
– In our company, the construction system is based on environmental materials. Primarily wood is used, wool, which is found in the walls and serves as insulation because it is environmentally friendly. The facade is wooden. All materials used in the construction of the house are certified, while the raw materials are imported – he adds.
Isolation is crucial
During the construction of this facility, the insulation must be of high quality and of a certain thickness, in order to maintain heat or cold, depending on the seasons.
– Insulation plays a crucial role, it is found in the walls, ceiling and roof and its thickness must be between 25 and 30 centimeters, in order to be effective. The standard of other prefabricated houses is insulation with a thickness of 10 centimeters – says Kalicanin.
If the future owners of environmental houses decide for the “turnkey” system, in that way they do not only take care of the construction, but move into the finished house, they take the furniture as they wish.
– The advantage of environmental houses is faster construction, while in parallel, the foundation can be built on the plot, and parts of the house can be assembled in a workshop. From one to two months, the house can be completely finished. Buyers in Serbia are opting more for this system, so that they do not have to do anything around the house. It is only up to them to buy the desired furniture and move into the facility – he adds.
Zero consumption as a construction goal
When building environmental houses, architecture tries to reduce various negative impacts on the environment. Recycled and used materials are important for the sustainability of architecture, explained Vladimir Lovric, a graduate engineer of architecture.
– Sustainable architecture seeks to reduce the negative impact on the environment by increasing efficiency and moderation in the use of materials, energy and spatial development. With quality thermal insulation on the outside of the walls of the building, quality carpentry and locksmithing with triple glazing, it is possible to reduce the need for heating and cooling – says Vladimir Lovric.
By using LED bulbs and smart home systems, it is possible to build an eco house of the future with zero consumption, ie a facility that produces the same amount of energy that it consumes.
– Sustainable architecture includes the use of recycled or used materials. The reduction in the use of new materials creates a corresponding reduction in the contained energy, which is used for their production – he adds.
By using all the elements of solar systems, it is possible to get a house that is energy efficient.
– The environmental principle implies the obligatory use of renewable energy sources, especially solar. By using all the elements of passive solar systems, it is possible to get an energy efficient house that saves energy. With the additional use of active solar systems, collectors for heating hot water and photovoltaic panels for converting the sun into electricity, it is possible to get zero energy houses – Lovric explained.
Mud and straw are becoming increasingly popular
Wood, brick, stone, straw and mud are not only in trend again, but modern eco-houses cannot be imagined without their partial or complete use during construction, said Lovric.
– Principles unite proven modern technologies with the use of classic materials and traditional construction methods is often applicable. By using natural, unpolluted materials from our environment, we reduce energy consumption – he claims.
Built as electricity producers
In the summer of this year, citizens who decide to install solar panels on their houses or buildings will be able to save electricity, and the cost-effectiveness of the panels is from seven to ten years.
– Also, citizens will be able to become producers of electricity as early as the summer of this year, if they decide to install solar panels, regardless of whether they live in a house or an apartment, on the basis of which their electricity bills will be reduced. The life of solar panels is 25 years, and the investment in them can pay off in seven to ten years – Vladimir Lovric reminds.
Dilapidated carpentry can be replaced with subsidies offered by the state, which amount to 50 percent of the price of windows and doors that will be found in the apartment, Kamatica reports.
