Five times lower household cost

A building of the future is constructing. A very good isolation, special bricks, vacuum panels, thermal bridges and solar walls will make household costs lower. Square is more expensive, but payable

OSIJEK – Since December of this year, 15 families in Osijek will move in first low-energy and self-keeping building which will have five times lower total costs than the average Croatian household, Jutarnji list writes. House of the future is building at the Reisner street, square price is 200 Euros more than in comon building in the neighbourhood, and it's estimated that investment on more expensive square will pay off in 3 to 5 years. Just in case of breakdown, temperature is 16 °C "We guarantee that temperature in the flat will not drop below 16 degrees of Celsius, and that will happen when all pumps and solar systems fail at the same time, which is impossible. This self-keeping system is more expensive than the standard constructing up to 15%, but it pays it off in 3 to 5 years", says projecter Glasnović. Smart building project is made for the first time in Croatia as Swiss example where Minergie standard is successfully applying.Its application on building of the future has came up by Chemistry and Technology University from Zagreb in cooperation with Swiss institute. Chief projecter dr.Zvonimir Glasnović claims that Minergie standard limits the total household consumption on heating, cooling, hot water and electricity to 3 liters of light cyan per year. "Entrepeneur Janoš Seleški told me at one symposium that his company Agria wants to build the first low-energy business-residential building in Croatia. We immediately agreed to turn one part of the complex in the Raisner street into house of the future. 200 meter probe is deeper, and concrete construction is building. Now follows the most tense part because constructors have to build everything as planned to get all the necessary certificates.“, says Glasnović. They achieved five times lower household costs by using methods of building active and passive low-energy houses with geo-thermal crane which is buried 215 meters below ground. For extremely good isolation, special brick, vacuum panels, thermal bridges and main sewer you need to use 42 kW h/m2 energy power per year. Investor Janoš Seleški fromiz Agria company said that he believed in this modern system efficiency which experts built and he will also live in that low-energy building, Jutarnji list writes. Croats pay 22.000 kunas per year on heating and electricity One quarter of expenses in average Croatian 4-member family is going away on household costs, that is 1600 to 1800 kunas per month or 19.200 to 21.600 kunas per year (Independent Croatian Union research and GfK agency research). For example, on heating of a 100m2 flat by using electricity, family will spend averagely 12.000 kunas; on heating by using light cyan they'll spend 7500, and on heating by using natural gas they'll spend around 4000, and by using woods 2500 kunas. Families in passive and active houses spend 2000 to 8000 kunas per year on all the household costs; heating, cooling, hot water and electricity. Depending on the way of heating (electricity, gas or woods) you can save up to 2 or 6 times more, and families that live in houses of the future say that average savings are five times higher.
