An ultra low-energy house is a type of house that, using design, technology and building materials, uses less energy than a traditional house and other modern houses.

In the practice of design, architecture and construction method, an ultra low energy house often uses active and passive solar energy, design techniques and components to reduce energy consumption.

Usually the use of the high levels of insulation, e.g. heat-insulating systems to prevent heat loss through walls, ceilings and basements along with energy-efficient windows.

This way of using the solar energy system also provides hot water for the household and at the same time for cooling the house.

Lighting and various energy consumption are equipped with low energy light and energy efficient appliances.

This type of house meets the new regulations and regulations for the construction of low-energy houses.
