Prefabricated houses ekokoncept: Technology
At ekokoncept we design and manufacture houses for future generations. Our diffused-open outside wall system does not contain any PVC foil or Styrofoam, both largely used in construction today. This means that the walls regulate humidity, which does not get caught in the construction system and therefore can not cause any damage to it. Also, the carefully determined layers within the walls are detached from the base plate, allowing the air (as well as humidity) to circle and dry the house. Everything else is up to the weather and seasons.

Starting points
NEG – low energy building
With choosing the right materials, correct dimensions and high-quality windows, we can achieve low-energy standard whit minimal assets. Low energy buildings require lower temperatures for heating, which makes them perfect for using alternative energy sources also used for cooling the building during the summer. This is very important, because global warming and use of excessive glazing in architecture today cause higher energy demands in the summer. ekokoncept energy efficient buildings meet the current top European standards, also applying our own, innovative manufacturing technologies.
A 3-liter low energy house must meet the following standards:
– specific heat loss – 20 W/m²
– energy used for heating
– 20-30 kWh/m²a
To achieve these standards it is necessary to meet the following Umax levels in the buildings shell elements;
– outside walls and walls (ceiling) bordering a unheated attic ≤ 0,18 W/m²K
– ceiling above the unheated basement ≤ 0,30 W/m²K
– sloped roof above a heated attic 0,15-0,20 W/m²K
– terrain floor with under floor heating ≤ 0,30 W/m²K
– doors and windows (glass and frame) ≤ 1,5 W/m²K (double glazing)
At ekokoncept we believe in environment-friendly and energy-efficient building materials and in the utilization of renewable energy sources. We are very aware of the importance of solar energy and the energy of the wind.
The sun provides a significant share of energy necessary for heating, warm water and electricity at large. We distinguish between:
– an active solar system (collectors/photovoltaic’s)
– passive solar system (large glazed surfaces facing south)
