Ö-quadrat - Ökologische und ökonomische Konzepte

Stromspar-Check for low-income families

The Federal Ministry for the Environment, Nature Conservation and Nuclear Safety in the Association office Ö-quadrat, Berliner Energy Agency and Energy Agency Regio Freiburg, implemented a pilot project. The task was to install electric saving and water technologies and analyse the effect of on-site energy advice. Additional inefficient refrigerators have been changed through high efficiency cooling devices in the Hartz-IV-households (households without own income).
In this pilot study, conducted in 2008, 108 Hartz-IV-households were studied, including 80 in Freiburg, and 28 in Berlin.

Advice to households and direct installation
The consulting services were carried out according to a special schedule and process. They included the measuring of the electric power consumption, the direct installation of energy saving lamps, TV stand-by-reducer, installation of switchable power strips, timers, perlators, flush-stop for the toilet and water-saving shower heads, or when required to support the replacement of existing inefficient refrigerators or freezers through high efficient appliances. The support was given through a grant of up to 300 € (max. half of the purchase price) and an additional micro-credit to cover the difference between purchase price and grant.

The analysis of the basis of the 108 Hartz-IV-households showed the following results:
    * Households could save on average 18% of their electricity consumption.
    * The cost per kilowatt saved were up 7 cents / kWh, well below the cost of
       producing, transporting and deliver electricity.
    * The average benefit per household was 840 Euro (over the life of the
       conservation technology; at constant current prices).
    * The CO2 emissions were reduced by 3.7 tons per household.

In a modified form, the project "Stromspar-Check" is currently implemented in more than 60 cities in Germany.
