The life of modern man brings into focus energy efficiency and using renewable energy sources. This is the idea that Easy Building introduces into your life offering elegant solutions for your home, cottage, office space or a guest house in the form of prefabricated building with high performance when it comes to saving energy. The energy crisis caused that today on a similarly way we approach when buying a car.

Buying or building a house is a big thing in someone life, usually done once in a lifetime. By investing in a house of this type, one decides to live or work in a pleasant and healthy environment at low cost for heating or cooling, hot water, etc. By investing in a house of this type, one decides to have something permanent and of a high quality being pleased to be able to hand it over as a legacy to the children or grandchildren.

Because of efficient insulation of laminated walls and optimized structures, our buildings are configured so that their average energy consumption for heating and hot water is between 4 and 6 liters of oil or cubic meters of gas per square meter of living space per year!Thermal insulation is excellent and for example, for our standard wall, is: U factor = 0.14 W/m2K

The use of wood leads to energy savings in the building, since its porous cell body provides exceptional thermal insulation. On average it is 15 times better than that of concrete, 400 times better than steel and 1700 times greater than that of aluminum. For example, 5 cm thick wooden wall insulates as well as 25 cm thick brick wall. The consequence of these facts and the increasingly stringent thermal requirements in building codes is that the houses made of wood became the optimal solution.Facilities being built by Easy Building are characterized by a specific mode of production (precision engineering and structuring) of elements and then their mounting, which ensure the sealing of the space to the maximum extent possible – so that a prerequisite for minimizing energy consumption for heating and cooling is achieved.

After completing the installation of the house, one of the quality control test is checking tightness of the building. This is done by blowing air (creating overpressure in the house) and recording the curve of equalization of air pressure inside and the pressure outside. Well Sealed Housing is a prerequisite for the energy efficiency of each building. In Easy Building facilities, include openings for windows, entrance and balcony doors are only 5mm larger than the dimensions of the interior components. This facilitates sealing of these critical compounds of each dwelling. In a classical building, this rate is often larger than 3cm. Having in mind that the danger of uncontrolled exploitation of fossil fuels is ascertained on the planetary level, EU has estabilished regulations concerning the building permit introducing the obligation of determining the energy efficiency of each planned building.

This regulations are becoming more severe in shorter intervals and getting the force of law. Today, for example, in Germany, a single building ca not be built if the total amount of the required primary energy does not consist of min. 20% of energy from renewable sources. In most cases it is solar energy. When using thermal pumps as a basic system for heating and hot water production, the percentage of energy from renewable sources is almost 100%. For this reason, in Western Europe residential buildings are increasingly equipped with thermal stations that use renewable energy sources and (or) solar panels to produce hot water or electricity.Our advice to you is to think of the house as a single system and take care of all parts rather than to focus on the selection of a material due to its theoretical value. No matter what the manufacturer says, the house is the sum of its parts (components). In this respect one should have in mind that a bad choice of one of the components can have a greater negative impact than all the positive effects of well-chosen components.

Thermal conductivity is a physical property of the material; only depends on the material and not the other characteristics (thickness, size). The thermal conductivity of the material is not easily measured. Usually there is a difference between the results of measurements in the laboratory (in ideal conditions) and what you will get in your house, in less than ideal conditions.

When evaluating the thermal insulation of the entire constructive component, all of its parts must be taken into account. To calculate the energy efficiency of the entire house, following things must be taken into account: the walls, floors, ceilings, roof, windows,… accordingly all its parts. Therefore, there is no reason to pay much more for the insulation of walls if we decide to save money when purchasing windows (other words if the windows that will be incorporated in it has bad characteristics in terms of thermal insulation). All parts and components have to be harmonized.
