As the first location in the Waldviertel housed the Dämmwette of the Energieberatung NÖ on the Sonnenplatz Großschönau. From 1st October 2012 to 31st March 2013 there were two model houses on the Sonnenplatz Großschönau and braved the winter in Waldviertel.
One with very good insulation, the other with little insulation, as it corresponds to the design of the 70s. A small furnace was keeping the internal temperature at comfortable 21 ° C.

The model houses
Insulation thickness "70s house”:
roof: 12 cm, wall: 5 cm (equivalent to 30 cm hollow bricks), window: Two-pane insulating glass

Insulation thickness "Modern house”
roof: 40 cm, wall: 30 cm (in wood frame construction), window: three-pane insulating glass

Ewald Grabner from the Energieberatung NÖ was happy about Großschönau as the first site in the Waldviertel, "Our Dämmwette fit thematically ideal for the Sonnenplatz Großschönau and its expertise in the field of energy efficiency."
This experiment demonstrates the enormous saving potential that exists in modern energy efficient construction. Sonnenplatz Großschönau was after St. Pölten, Kirchschlag in the Buckligen Welt and Pressbaum the already fourth location of the Dämmwette.

After six months, the energy consumption in a well-insulated passive house and a poorly insulated house of the 70s was compared. The final result shows that the passive house needs 76.40 percent less energy than the house from the 70s. The savings would have been even greater if more hours of sunshine in the winter months would have brought higher solar gains.

After six months in the harsh cold winter air of the Waldviertel was clear that the insula-tion delivers what it promises. While the existing model consumed 758 kWh of energy, the passive house model required only 179 kWh. The lower heating costs correspond to a saving of almost 60 euros per square meter in heating season.

The evening event of the 11th schönauerExpertentage was held on 8th November thematically fitting with the motto "klima:aktiv award event 2012" and in cooperation with the green building cluster of lower Austria and the Energy and Environment Agency of Lower Austria (eNu). A part of this celebration was the receipt of the klima:aktiv-distinction of the Sonnenplatz Großschönau for the construction of the research and competence centre for construction and energy.

A total of four excellent service buildings in Lower Austria were awarded with the klima:aktiv GOLD:
• Rehabilitation of the district administration Lilienfeld
• Office buildings in Weidmüller IZ NÖ-south in Wr. Neudorf
• Office and event building Sonnentor Kräuterhandels GmbH, Sprögnitz (klima:aktiv Gold)
research and competence centre for construction and energy, Großschönau (klima:aktiv Gold)

The klima:aktiv building standard is the quality mark of the Austrian Federal Ministry of Agriculture, Forestry, Environment and Water Management for sustainable buildings with a special focus on climate protection and energy saving in Austria. So energy efficient, ecological and comfortable living and work is guaranteed. Klima:aktiv buildings are designed and constructed for making independent from energy price developments. The klima:aktiv standards make the quality of a building measurable and comparable.

Klima:aktiv is the climate initiative of the Austrian Federal Ministry of Agriculture, Forestry, Environment and Water Management launched in 2004. The goal is to launch and disseminate climate-friendly technologies and services in the areas of building and renovation, energy conservation, renewable energy and mobility. The program klima:aktiv building and renovation is a central component of the climate protection initiative when it comes to energy-efficient new building or a high-quality restoration in Austria.

As a part of the BIOEM on 31st may the TDW Großschönau organized a symposium in the new research and competence centre at Sonnenplatz. Invited were 100 people from all over Austria and neighbouring countries. In the centre of the all-day event was the theme "energy future of our communities." TDW Chairman Josef Bruckner welcomed the numerous guests of honour and the high-calibre speakers. DI Franz Angerer of the head office of the Energieberatung NÖ pointed that 1.6 million people are responsible for the energy consumption in Lower Austria. The challenge is to explain to these 1.6 million people that energy is precious to us and is no longer available in unlimited quantities. After the keynote speech by Mayor Dr. Peter Brandauer from Werfenweng the results of two research projects in the area of smart grids and CO2-neutral communities in rural areas of the program line "New Energies 2020" were presented. Großschönau takes decisive role in these projects as a test site and project applicant. This “GAVE project - Großschönau as a virtual energy storage” was presented by DI Dr. Fried Kupzog (Vienna Univer-sity of Technology ICT) and Max Blöchle, MSc (AIT Energy Department). The results from the Zero Carbon Town project were presented by DI (FH) Luke Lippert (AIT Energy Department) and DI Mag Wolfgang Prüggler (TU Vienna EEG). These projects prove that Großschönau is already one of the six pioneer regions in Austria concerning these themes.
The afternoon was devoted to the first energy-efficient mobility. The relevant papers came from Peter Mag Czermak by the Climate Alliance Austria and DI (FH) Jörg Worschech of Eco Plus NÖ.
Currently, there are already 85 Climate and Energy model regions in Austria. Mag Wolf Christoph Egger, MSc, from the Climate and Energy Fund reported on the tender, in which the 100th KEM-region is to be found. Ing Otmar, head of the Energy Agency of the Regions, hits on the basis of the 29 KEM-regions in Lower Austria that efforts are more than just a short trend toward energy independence.
Concrete results from the climate and energy model region "Lainsitztal and environment" were presented by Mayor Martin Bruckner. Finally Johann Hofbauer brought the greetings on behalf of Governor Dr. Erwin Pröll.

In this year 20 cities, municipalities and regions from nine European countries have received the Climate Star 2012. The Climate Stars have been presented on invitation of the Regional Authority of Lower Austria during a gala at Schloss Hof on 26 April 2012. Including also the Member of the Climate Alliance Großschönau in Lower Austria.

The winning project „Construction and energy at the Sonnenplatz“ (category regions)
In the beginning there was the environmental trade fair in Austria; Bio-Energiemesse BIOEM. It has now been held 27 times. Sonnenplatz (sunny place) was inaugurated in 2007 and the first European passive home village opened for test living. The focus is on energy saving construction,
renovation and living. Five passive homes in various styles were available for testing and experiencing for all those interested in building and renovating. An educational department was also set up at the same time. The research and training centre for building and energy opened in November 2011. One-point-nine million euros were invested with expertise coming directly from the region. A lot of the planners and craftsmen involved in the planning and building of the passive houses were trained and educated in Großschönau. The modern training rooms are used to train and educate building planners, craftsmen, technicians and municipal politicians. Just in the first three months of 2012, 90 people were trained as passive house craftsmen, planners and energy advisors. In 2013 Sonnenplatz will be expanded to include Sonnenwelt (Solar World) – an exhibit available throughout the year discussing energy-efficient construction, homes, renovation and living.

In May 2011, the first European passive house village in Großschönau celebrated its fourth birthday and now there was a second jubilee: Sonnenplatz was able to welcome its 4444th guest visitor who tested a passive house in this unique village. The mayor of Großschönau Martin Bruckner welcomed Anton Koczur and his wife Christiane from Groß Siegharts and gave them a little present.
The delight about the successful development of the showcase is a great pleasure for the initiators of the Sonnenplatz project; Sonnenplatz is visited by more than 1000 visitors annually. Martin Bruckner is sure: “We are able to contribute to the dissemination of energy efficient- building, -reconstruction and -living with our efforts. The company neutral consulting of the people who spend some days in our passive houses is very important for us.” The family Koczur spent two nights in the certified house made out of bricks from the company Schiller and they were enthusiastic about the possibility of test-living. They said: “The practical part is always better than the theoretical one.”
The former president of the federal state government and the former mayor of Groß Siegharts Anton Koczur pointed out, that it is very remainable, that a small municipality like Großschönau is able to do such great things. Through the intensive work with the energy-topic, Sonnenplatz works in cooperation with the federal government and does great work for a better future.” He recommends every interested person to test-live a passive house at Sonnenplatz and to get a feeling for energy-efficient living.
