Children’s learning abilities
increase by 15% if they are in a good
indoor climate
We spend up to 90% of our time indoors –
living, working, learning and playing
TOWARDS MORE SUSTAINABLE BUILDINGS: SOCIAL IMPACT
Productivity
increases by 18% with
access to daylight
Nearly 65% of office workers are
distracted by too much
noise

Heat needs
6 kWh/m²y
House in Vienna with Triple Glazing with SGG PLANITHERM MAX Ug = 0.6 W/m²K and g = 0.60
Wall U=0.12 W/m²K
Solar gains compensate for the difference in thermal insulation
Having more glazing is favorable!
