Electricity saving family
Electricity saving family
Phase I: 2010 – 2012
Background: Electricity target of lower Austria: :
100% of electricity from renewables in 2015
Energy efficiency is a precondition to increase
the share of renewables in the electricity market
Target of the initiative: exploitation of electricity
saving potential in private households
![Page 8: The Electricity Saving Family - a case study](https://reader034.vdocuments.net/reader034/viewer/2022052311/559e82c51a28ab377d8b45d7/html5/thumbnails/8.jpg)
Electricity saving family
Electricity saving contest for households
Energy consulting for free at the start
Incl. report
Suggestions for improvements
Energy meter for free
All participants were asked to document the
electricity demand monthly „Electricity dairy“
Analysis was offered
Possibility for comparison

Electricity saving family
Awareness activities using public media
(advertisement in newspaper)
Promotion through “energy hotline”
Smart Meter in some regions
Energy consulting after one year
Final event with regional minister
Prices for families with the highest
savings (absolute and relative)

Conclusion
Targets of the project have been fulfilled
10% - 15 % of savings with energy consulting realistic
No loss of comfort or high investments were mentioned
Willingness for investment mainly for electric appliances
No significant influence of smart meter over the period
Very high savings sometimes caused by “special
effects”
