SINERGO s120 PASSIVE HOUSE
m2 living area
m2 total area including terrace and garage
A house without heating costs
If the house is equipped with solar panels, it is possible to produce as much electricity as is required to recoup the electrical heating costs throughout the year, making this house a zero-energy building, i.e., a house without heating costs!
Large windows on the south side with excellent sound and heat insulation
The windows are like solar collectors that heat the rooms in winter, spring and autumn, while the window overhang prevents the house from overheating in summer.
Efficient ventilation with heat recovery
The automatic ventilation system provides fresh air all year round, without the need for dedicated ventilation of the house.
Well thought-out building structures
The excellent heat insulation, building structures without thermal bridges, the airtightness of the building and especially warm windows ensure a constant temperature in all corners of the house, even next to a window when the outside temperature is -10°C!
Passive house design uses the PHPP energy balance calculations in which all geometrical building data, thermal and physical properties or materials, data about the house users, heating and the ventilation system loading schedule are entered in detail and the building orientation and Latvian climate data are taken into account. Such calculations are required to verify if the house meets the Passive House standard.
- Annual heating demand – 15-20 kWh/(m²a);
- Air tightness (n50) – 0,4 h-1;
- Heating load – 18.5 W/ m²;
- Primary energy requirement (incl. solar energy gains) – 9.38 kWh/m² gadā.
Annual heating demand if house is positioned:
- to south – 15kWh/(m²a);
- to west – 27kWh/(m²a);
- to east – 28kWh/(m²a);
- to north -34kWh/(m²a).
