Many older buildings have a heat requirement of over 200 kWh/(m²a). Expressed in terms of heating oil, this means that approximately 20 liters of fuel are needed during one heating period per square meter of living space per year. The corresponding gas equivalent would be about 20 m³ of gas per square meter per year. Consequently, a single-family house with 150 m² of heated living space and a heat requirement of 200 kWh/(m²a) consumes approximately 3000 liters of heating oil or 3000 m³ of gas per heating period. These consumption figures can be considerably reduced by means of energy-related improvement measures. Studies have shown that energy savings of more than 50% can easily be achieved through thermal insulation (source: Institut Wohnen und Umwelt, Germany).The money spent exclusively for the thermal insulation is often already recouped after just one heating period. The benefits to the environment are selfevident.
