Energy-efficient renovation of a single-family house
built in 1967
Building floor space: 230 m²
Insulation thickness: 14 cm with WLG032
Additional energy-saving measures: new roof
covering, new between-rafter insulation in the attic,
replacement of low-temperature heating system from
1990 with gas condensing boiler
Planned measures: thermal solar system (approx.
12 m² vacuum tube collectors), triple glazing
Ralf Bayer, owner:
“When we took over the house from my parents in
1996, we discovered that the indoor climate was very
uncomfortable and cold. There was even a draft
coming through the power points. We now use 20%
less energy and the exterior walls are warm on the
inside, even in winter.”
