3) Windows 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)Isolating materials1) Indoor isolation2) Outdoor isolation
3.1 Indoor isolation
Isover – PIANO - soft, under pressure rolled strip of insulating glass fibers with excellent sound insulation
3.2 Outdoor isolatiom
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
Outdoor Isolation
4) Redeemable sources
1) Solar energy
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 technologiesRAYWALL 45 (reflector grid for normal incidence solar radiation)RAYWALL 90 (reflective screen for an impact angle of solar radiation)
Active raster
Methods of solar energySolar 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
