    7 th June 2011
  • Passive housing
    • Reduction of energy consumption
        • up to 90%
        • 15 kWh/m 2 per year instead of 120 kWh/m 2 per year
    • Starting from 2020 – obligatory standard for the entire European Union
    7 th June 2011
  • Features of the passive house
    • Superinsulation
    • Compact shape
    • Exposure towards the equator
    • Right fenestration

  • Bioclimatic design in ‘HOUSE 2020’ Ground Floor First Floor Cross-section 7 th June 2011
    • We achieve reduced energy demand for heating by:
    • smart design
    • increasing thermal insulation
    • air tightening the building envelope
    • installing high performance windows
    • incorporating an HRV system
    And as a final product we are receiving… Passive house concept 7 th June 2011
  • Passive house concept 7 th June 2011
  • The risk deriving from thermal insulation
    • Excessive moisture of building partitions causes:
    • deterioration of the interior microclimate
    • a good environment for microbial growth
    • decrease in thermal insulation of materials
    • corrosion and destruction of partitions
