| Passive House Days Attendance: |  '11 '12 | |||
| Building type: | terraced house (low energy new build with PH components) | |||
| Project description: | Prefabricated wood, local sheep's wool insulation and wood fibre. Construction price less than 1100/m2. Build time, 6 months. Energy consumption heating 10kwh/m2 year PHPP. Minimum gray energy of materials. Positive CO2 balance. Minimized ecological footprint. Adapted to the European guidelines for low consumption 2012-2020. With 6m2 of PV power generation could be a ZEB (Zero Emission Building). Annual heating cost, 250. Removable. | |||

| Miscellaneous: | Editor's note: To define a building as a passive house, the criteria for the heating demand, the primary energy and the building airtightness are to be observed.
Editor's note: The verification considers local climate data. In Central European Climate the U-values of opaque building elements are recommended to be less than 0,15 W/(mēK). In case of deviating climate conditions this may require review, U-values are always linked to specific climate data. Thermal bridges should be considered. | |||
