Zero energy home

They are regular grid-tied homes that are so air-tight, well insulated, and energy efficient that they produce as much renewable energy as they consume over the course of a year, leaving the occupants with a net zero energy bill, and a carbon-free home.

Increased energy efficiency

SINERGO houses are built according to the Passive House construction standards. These are houses with very high energy efficiency, in which a comfortable indoor climate can be maintained without active heating or cooling systems.

Well-being and comfort

Exceptional thermal insulation and excellent building air-tightness protects a house from the risk of accumulation of moisture, mold and condensation.

Effective ventilation

Pleasant and fresh air inside the house is provided by an automatic ventilation system which keeps the air pleasantly warm, fresh and clean from dust.

Green and ecological construction

SINERGO houses are designed to use as much natural material as possible in the construction process. The house is built from high-quality wood and is heat-insulated with natural cellulose and wood fibre boards.

Live in a house built according to Passive House construction standards!

High energy efficiency GUARANTEED!


savings on heating costs compared to conventional houses

Heat consumption comparison

  • Passive house – (≤15kWh/m2/a) 5% 5%
  • Very well insulated building – (40-60kWh/m2/a) 30% 30%
  • Average insulated building – (60-100kWh/m2/a) 50% 50%
  • Non-insulated building – (150-300kWh/m2/a) 100% 100%

By living in a passive house you will save up to €2,000 per year! **

* European Parliament Directive 2010/31/EU requires that by 31 December 2020 all new buildings in member states of the European Union must comply with the passive house standard for energy efficiency.
