What is eNu?

The Energy and Environment Agency of Lower Austria is THE

point of contact for all questions concerning energy,

environmental protection and the preservation of nature.

It is known as a competence center and unites the know-how of

the following initiatives:

33-Formula

3 Services:

Consulting, Research/Awareness building, Public Relations

3 Topics:

Energy & Climate

Environment & Lifestyle

Nature & Resources

3 Target Groups:

Citizens

Municipalities / Public Institutions

Enterprises

appointed energy officers by municipalities

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

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)

Statistics

Number of participating families 229 (310)

Thereof Smart meter 56

Size of the family:

1 person : 8

2 person : 41

3 person : 31

4 person : 66

> 4 person : 47

Companies :36

Outcomes – overview

Electricity demand start : 1.521.579 kWh

Electricity demand final : 1.329.189 kWh

Savings : -192.390 kWh (= 55 households)

Families with savings: : 80%

Average savings: 12,6%

Main saving potentials

Fan heater as additional heating system

Ventilation system

Whirlpool on 37°C (as an example)

Fan heater in winter garden

Inefficient appliances

Lighting

….

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”

Electricity saving family II

New elements/design:

Web-based only

No mandatory energy consultation – but

recommended

„open end“ but annual award

Monthly electricity accounting -1st day per

month (reminder per Email)

Annual electricity bill for verification

Competitions between regions

Start in September 2014

Lower Austria electricity saving bet

Electricity saving bet (For all participants):

Precondition: saving 5% or more and monthly electricity accounting

Main prices :

E-Scooter

Energy efficient washing machine

For regions and lower citizen only

Lower Austria bet:

Every 4 month you can win a bottle of wine or LED lamps in a lottery if you reach your goal

Regions families within a can form region teams they can challenge each other and also win non-cash prizes
