Nearly Zero-Energy Houses

In 2020, the Energy Performance of Buildings Directive enters into force, the intention of which is primarily to reduce harmful emissions into the atmosphere and to increase energy performance and the use of renewable sources. From the next year on, the construction of nearly zero-energy buildings will be mandatory for all types of new buildings. At Rihter, we have been building in compliance with or even above the prescribed standards of this Directive for many years. All our construction systems are classified as nearly zero-energy buildings.

A nearly zero-energy building is essentially an excellent low-energy or passive house. It is built in line with the best energy standards; however, as outside temperatures are significantly different to those people prefer in their houses, additional energy for temperature regulation is still required. In addition to energy needs to maintain a suitable temperature in the house, there is also the need for the electricity that residents require for performing everyday functions.

Energy needs in a prefabricated house are minimal, yet some costs are still incurred. This energy can be supplied in full by installing solar panels, which generate all the electricity necessary with the help of the sun. In this case, your house can become completely independent and self-sufficient energy-wise.

If the number of installed panels exceeds the house’s energy needs, we refer to energy surplus creation. Currently, surpluses of small solar power systems are not sold through the network, so it is necessary to carefully plan the capacity of the residential solar power system. It is worth considering a form of electrical mobility if the residential solar power system generates an electricity surplus. At Rihter, we can offer you all that when you purchase a Rihter house.

During the development of a house, special attention must be paid to its thermal envelope, which is one of the most important parts of every prefabricated building. As we are well aware of this, we have developed several construction systems, which have been certified by various international certification bodies. The thermal insulation in the envelope prevents cooling of the building during winter and its overheating during summer. The thermal insulation of Rihter construction systems significantly exceeds the statutory requirements regarding heat transfer of external structural components.

All Rihter construction systems, except for the Rihter Natura system, use rock wool as thermal insulation between the load-bearing construction. In Optimal, Optimal+ and Pasiv systems, the rock wool is used for the thermal insulation of the facade. Thus, we ensure low consumption of energy, excellent sound insulation and fire safety.

All Rihter prefabricated houses are made from wood, which is an exceptional thermal insulator. Despite its low density, it is distinguished by its excellent mechanical properties, which ensure that prefabricated construction provides seismic safety. With the help of the latest technology and top-quality building materials, Rihter houses create a comfortable and healthy environment.

Nearly zero-energy houses Rihter are built in accordance with the top energy standards, ensuring minimum consumption of energy and maximum comfort of living for their residents.
