Czernohorszky / Gaal: In Simmering smart climate protection makes school
"We have created an innovative project at a very important school location here,“ said a pleased Education Councilor Jürgen Czernohorszky. "So not only a new modern school room emerged, but succeeded with Smart City solutions an appreciation of the whole district quarter, which is indeed a EducationQuarter! For me, the inclusion of pupils and teachers in the design process was particularly important.“
"Climate protection makes school here. The ideas and wishes of the students and teachers were included. The result is an innovative, ’smart‘ school – with ‚zero-energy gyms‘, plenty of space for athletes, solar benches for charging smartphones and more," said a delighted women’s and housing councilor and "Smarter Together" patron Kathrin Gaál. Adding: "An entire district quarter in Simmering is being upgraded by the EU-sponsored ‚Smarter Together‘ urban renewal initiative,“ said Gaál.
"This school extension is literally a showcase project. The underground gymnasiums in zero-energy construction were a special challenge. For the use of geothermal heat numerous deep holes were necessary. And otherwise, the extension plays all pieces of state-of-the-art home and energy technology," said Wien Holding Managing Director Sigrid Oblak.
Smart school extension NMS Enkplatz benefits 1000 pupils and the local population
On the 9th of October 2019, the City Councilor for Education Jürgen Czernohorszky, housing councilor Kathrin Gaál, Education Director Heinrich Himmer, Head of District Paul Stadler and Wien Holding Managing Director Sigrid Oblak officially opened the new rooms at 11 am. At the heart of the smart extension, designed by the architects Burtscher & Durig, are four underground gymnasiums, as well as the above-ground extension with 13 classes, 4 leisure classes and various special education rooms. In total, the construction project comprises 3,800 m2 of gross floor space and 3,500 m2 of outdoor sports space. The school extension was developed in close cooperation with the EU-funded Smarter Together urban renewal project and includes a number of innovative technologies designed to ensure a zero energy balance. The pupils and teachers were also involved.
On the occasion of the school opening, the street workers of Balu&DU resp. Mojosa and the GB * offered a colorful program that was wonderfully welcomed by the kids. A big thank you for your commitment.
"Smarter Together": good climate in the Simmering school through sustainable "zero energy construction“
A special feature of the annex building, which was implemented as part of the EU-funded urban renewal project "Smarter Together“, put climate protection and sustainability in the foreground. The annex building with four "zero energy gyms“, 13 classrooms, four leisure classes and open break and work areas and a new school library is available to the approximately 1,000 students. The school extension building will be connected to the listed building in the form of a walkway. The new stairwells with lifts enable barrier-free access not only to the new building but also to the existing school building.
Climate neutral: Energy is generated locally
In total, the smart school extension includes 3,800 square meters of gross floor space and 3,500 square meters of outdoor sports grounds – located above the underground zero-energy gymnasiums. "Zero energy“ means generating as much energy in the year on site as it consumes, which is carbon neutral in operation and long term cost effective for the city.
The centerpiece is the special building technology concept with a 350 square meter photovoltaic system, 16 deep geothermal probes and the use of geothermal energy via heat pumps. In addition, excess energy is fed back into the district heating network via a system of 318 m² of solar thermal collectors. There is also "Free Cooling“ in summer, the underfloor heating is used for cooling (tempering).
A school with a great design and wow-effect that makes kids want to go to school even more
In the forecourt of the two schools are solar benches – innovative seating that offers the ability to charge smartphones via integrated photovoltaic cells. The blue and green runs to the arcade glow brightly, the modern design of the arcades reminds one of a river. Two colorful "enzi-benches“ from MuseumsQuartier in downtown, painted by the students, welcomed visitors ar the entrance of the school.
Before the conversion, "SIMmobil“, the mobile communication laboratory of the EU program "Smarter Together“, was in use in front of the school. In June 2017 students and teachers were asked for their ideas regarding school improvements and the results flowed into the planning. This turned the students into ambassadors for the Smart City. A wish of the pupils was realised: A climbing wall was built.
The public and school were regularly informed about the progress of the project. For further insights, the energy data of the school will in future automatically be delivered every quarter of an hour to a data platform and evaluated by experts of the City of Vienna.
The city of Vienna invested around 27 million euros in the project. The school extension building is at the heart of the Smarter Together urban renewal initiative of the EU.
The project was implemented by the WIP Wiener Infrastruktur Projekt GmbH, a company of the Wien Holding subsidiary WSE Wiener Standortentwicklung GmbH, on behalf of the City of Vienna – Vienna Schools and in close cooperation with the City Building Directorate Vienna.
Conclusion: A school with all imaginable innovations and comforts
The school expansion of the New Middle Schools at Enkplatz 4 addresses all areas of importance. From modern design, to sports opportunities, blue and green trails to the meandering arcades and huge open space. The centerpiece is the modern building services engineering with 16 deep geothermal probes, heat pump, PV systems, solar heat, recovery of surplus energy into the district heating network. This is groundbreaking for Vienna and has aroused great interest in the international network of Smarter Together.
Above all, the Meander design that can be seen from the outside is present in many different places: in the benches in the courtyard, on the door plates, on the glass surfaces as protective foils and especially in the arcade.
DOSSIER extension NMS Enkplatz, background information
The listed double school from the 1970s houses an arts and sports school (NMS and ONMS). It suffered from a lack of space, and some classes had to be outsourced. The two outdated and non-renewable gyms had for instance had only one toilet for boys and girls together.
As part of Smarter Together, the idea was born to obtain EU funds for a forward-looking, energy-efficient refurbishment. A first feasibility study was prepared. This showed the energetic potential of a new building, in which geothermal energy could be used. An EU-wide architectural competition was announced. 34 architects from 5 EU countries, with Ulrich Burtscher and Marianne Durig, finally being accepted. The underground layout of the gymnasiums reduced the gross floor area and saved costs with a total cost of 27 million euros. The innovative energy concept comes from Vasko & Partner.
The new stairwells with lift enable barrier-free access not only to the new building but also to the existing school building.
As part of the preparations, the mobile communication lab of Smarter Together, "SIMmobil“ was used. In June 2017 it was positioned in front of the school and a survey was made of pupils and teachers about their wishes for their school of the future. The results were incorporated in the planning activities of the architects (bolder climbing wall, possibility of manual ventilation of the gymnasiums). An Austrian exchange brought further innovative ideas and insights that flowed into the planning.
Additional activities: numerous workshops with the children in the two schools, workshops through the Science Pool, Research Festival, Beat the Street, 2 solar benches in the forecourt (November 2017), and 2 Enzi-benches from MuseumsQuartier (MQ) have been in the forecourt since June 2019 painted.
A "sporty“ school building in fast motion
From February to May 2015, Smarter Together was designed as a project. The central "political“ task of Michael Ludwig was to ensure maximum citizen participation. Encouraged by this mandate, the two NMSs were quickly integrated in the project in order to include children on the Smart City voyage.
Timelapse: The idea of energy refurbishment of the old gymnasiums (spring 2015), a feasibility study for new gyms was made available (September 2016), council decision (October 21, 2016), pupil survey on the extension building in SIMmobil (June 2017), Europe-wide realisation competition (7 weeks , April to May 2017), winner Burtscher & Durig (general planner), commissioning July 2017, start of construction (January 2018), official ground-breaking ceremony (1 March 2018), trial operation (May 2018), regular operation (2 September 2019), official handover (9 October 2019).
Project partners who are committed to excellence and create synergies
The cooperation of the project partners was a key to success: the municipal departments MA 25, MA 56, the Municipal Council (budgeting), the architects Burtscher & Durig, WIP Wiener Infrastruktur Projekt GmbH, a subsidiary of WSE, Wiener Standortentwicklung GmbH, the construction company ÖSTU STETTIN, Vasko & Partner (house technique), the Wien Energie (total energy concept and recoup to the district heating network), the municipal department MA 34, which is responsible for the monitoring of the building services right up to the end of the project and analyses the data together with the AIT on behalf of Smarter Together.
Energy concept and EU funding
The gymnasiums are executed in "zero energy construction“. In addition to a photovoltaic system, the building services concept also envisages the use of geothermal energy in conjunction with heat pumps. In addition, in cooperation with Wien Energie, a solar thermal system was built which will feed excess heat into the district heating network. For optimum indoor air quality, a ventilation system with heat recovery is planned for the gymnasiums.
- PV system with 350 m² collector surface and a capacity of 64,000 kWh / year
