The worst energy offenders: the lineup
About a third of annual energy consumption in Germany goes toward heating buildings. In households, about 78 percent of energy used is for heating. Here, you can learn more about the worst energy offenders in your own home.
When it comes to energy consumption in homes, exterior walls, roofs, foundation floors and windows are often true energy wasters, since that is where the most heat escapes. In Germany, existing buildings present the greatest potential for energy savings, because they require about three times as much energy to heat as new buildings.
Old boilers often lose a lot of heat
We shouldn’t get too attached to old equipment – especially old boilers. Their heat shielding leaves a great deal to be desired, allowing for a heat loss of 8% in some cases. Good insulation can cut this figure down to 1.5%. Exposed heating pipes in locations such as basements should also be insulated.
When it comes to electronic equipment, you can use the EU labels as a guide to saving energy. These labels consist of seven colored arrows with the letters A through G. These letters stand for energy efficiency classes, with a device falling under Class A being especially efficient in its use of energy and devices in Class G using particularly high amounts of energy. For cooling equipment there are two additional categories, A+ and A++, which are used to designate the champions of thrifty energy use.
