How to get to the "passive house"

Montenegro must accept the standards of the European Union to reduce energy consumption and carbon dioxide emissions by 2020% by 20, but also to have the same percentage of renewable energy sources, it was ordered at the passive house seminar held at the Faculty of Architecture.

University of Zagreb professor Ljubomir Miščević explained that the passive house is the name for a new construction standard that implies a pleasant temperature in homes throughout the year without additional heating or cooling systems.

Citizens are interested in ways of saving, and the most frequent questions are "how much does it all cost".

"The passive house is ten percent more expensive than standard construction in the countries of the European Union. Croatian experience shows that it is up to 15 percent. We won't achieve it until 2020, but it's time for our people to start thinking about energy efficiency," Miščević said.

Green loans

Those interested in advanced construction have the option of asking banks for so-called green loans, while, as Miščević says, the state also has an "obligation to repair the windows on its buildings."

"It is important that incentives, which should first come from the state, can only be given for advanced construction and with loans with special interest rates. In that case, this 10 or 15 percent more expensive construction would be covered by those incentives," he said.

When asked whether the country's energy efficiency will be advocated due to economy or pressure from the European Union, Miščević said that the Balkan countries will have to accept the rules of conduct, and that the pressure towards more efficient use of energy is positive.

Participants of the two-day seminar, architectural, construction and mechanical engineers and students, will learn about the international criteria for the construction and design of passive houses and the methods used in the design and calculation of energy consumption in them.

The seminar was organized by the German Society for International Cooperation GIZ and the Faculty of Architecture as part of the project Improving Energy Efficiency in Montenegro.

Hermetically sealed space

The first passive house was built in Germany in 1991. It was about a study that was supervised by the German Ministry of Environmental Protection, writes dom.hr

Since then, the term "Passive house" has been used for every house in which no more than 1,5 liters of fuel oil or 1,5 m of gas is used per square meter of living space.

These are sensational values ​​even today, and whoever owns such a house really saves on heating.

Many confuse the term "Passive House" with "Low-Energy House", the difference is that a low-energy house has achieved a construction standard and a low-energy house is one that consumes a maximum of 7 liters of fuel oil, or 7 m of gas per m of living space per year.

The concept of the house, the position, the insulation and their calculations must meet high standards and it is necessary to get an almost hermetically sealed space inside the house, because otherwise the precious heat would escape through joints, joints and various openings.
