  1. Windows have an important function in the energy plus house . To meet the requirements of the Passivhaus standard, windows are manufactured with exceptionally high R-values (low U-values, typically 0.85 to 0.70 W/(m².K) for the entire window including the frame). These normally combine triple-pane insulated glazing (with a good solar heat-gain coefficient 3) Windows

  2. 3)Isolatingmaterials • Indoor isolation • Outdoor isolation

  3. 3.1 Indoorisolation Isover – PIANO - soft, under pressure rolled strip of insulating glass fibers with excellent sound insulation

  4. 3.2 Outdoorisolatiom

  5. Fibreboard is a proven large-scale insulating material for use indoors and outdoors. They are from domestic production, made ​​of spruce wood chips • 7 reasons for fibreboard: -are environmentally , made ​​from natural raw materials -production does not pollute the environment, are fully recyclable -excellent thermal properties λD = 0.039 W / mK -the highest specific heat capacity of insulation between C = 2100 J / kg.K -high permeability μ = 5 - is diffusion open for the passage of water vapor -equalize air humidity as well as natural wood - they absorb moisture and issued -excellent acoustic properties - suitable for sound absorption and impact sound

  6. OutdoorIsolation

  7. 4) Redeemablesources • Solar energy

  8. 4. Solar energy Active raster -linear lenses of their function still need other technical elements and they are a part of a solar collector concentration, raster linear Fresnel lenses are designed and manufactured for pitched roofs and facades and are corrected for normal and oblique impact of solar radiation Passive raster -operate without the use of other technologies RAYWALL 45 (reflector grid for normal incidence solar radiation) RAYWALL 90 (reflective screen for an impact angle of solar radiation)

  9. Active raster

  10. Methodsofsolarenergy Solar energy that reaches Earth's surface can be used active, passive and biological methods. Under actively understand the conversion of sunlight into heat or electricity. Heat supplied to thermal solar collectors of various types
