The Passivehouse project was developed in 2017-2018
Passive House has established itself as the internationally acknowledged standard for energy efficient architecture.
This 320 sq.m. building, designed to the Passive House standard, consumes energy equivalent to the energy consumed by a standard 80 sq.m. apartment.
Research has shown the energy consumption for heating and cooling in Passive House buildings to be roughly 80 percent lower than in conventional buildings.
Passive House offers a realistic option for cost-effective structures that provide high levels of comfort while using very little energy for heating and cooling.
In the face of rapidly increasing energy prices, this makes Passive House an economically attractive option. For homeowners and residents, it is also a chance to gain independence from volatile energy markets. The energy needs of a Passive House building are so low, that they can easily be met with active solar gains or other renewable sources located either onsite or

The level to the north of the property is about 1 m below the street level.
The ground level displacement within the property, in the north-south direction is 2 m.
Due to the specifics of the terrain, the building was decided on five levels.
