PopUp Dorms won the Sustainable Construction Grand Prize of the 2019 Green Solutions Awards at the national level + a mention for the international Sustainable Construction Grand Prize.
The PopUp dorms – affordable and sustainable housing for students
The PopUp dorms are highly energy efficient student dormitories. But they are much more, than just built to most energy efficient and sustainable building standard. Made of pre-fabricated sustainable timber construction, the PopUp dorms were built extremely quickly. The project shows how quickly and inexpensively passive house buildings can be constructed. In addition, this pioneer project saves a lot of the expensive property costs. A reaction to the discussion about affordable housing over the past several years, the idea was to take advantage of currently unused property for temporary, affordable housing – temporary student dorms. When the final use of the property is nearing, the dorms can be easily moved to a new location.
The first section for 40 students was built in Vienna's Seestadt Aspern district. The basic plan for this section called "GreenFlexStudios" – with ten residential groups surrounding a large, attractive two-storey atrium courtyard– was highly convincing and raised expectations for quality. The project shows that temporary housing and design can be well combined. Like the high-quality architecture and structural engineering, the compact concept for energy and building services also features many innovations. Each of the ten dwellings has a completely independent design, is self-sustaining and can be moved multiple times, including the interior facilities.
The basic layout of the PopUp dorms – 10 accommodation sections around the large, attractive, 2-storey atrium courtyards – was convincing and promises high quality standards. It proves that temporary accommodation and design can easily be linked. The covered courtyard of 250 m² is both an opening and a central community area of the house. It is lit by cupolas in the roof. It is also the heart of the building and provides the residents with spaciousness.Despite the very limited budget, this multi-functional meeting area is very important. A lounge area in the center of the 2-level, spacious room is the communication center. Moreover, a communal kitchen and a cleaning and laundry room are in a reconstructed shipping container and are part of the courtyard.
Each accommodation section with its 4 room units can be accessed via the courtyard. The 4 rooms are equipped with 2 bathrooms and an additional small common room with a mini-kitchen. Although this intimate communal area is separated from the courtyard, visual connections are still possible. A small loggia on the upper floor offers an additional communal area. Apart from the high quality in architecture and construction technology, the compact energy and technology concept exhibits many innovations. Each of the ten accommodation sections is completely self-sufficient and functional, and can be relocated to various properties five times within 40 years including their furniture.
Built and ready for occupation in no time
After the submission of building plans in January 2015 and a 2-monthfabrication period, the PopUp dorms were assembled as of 18 August 2015. After only one month, they were ready for occupation and handed over to the developers on 16 September 2015. The setup time (to the topping-out ceremony)including the assembly of all delivered parts took only six working days.
Low costs of property, construction and operation
This project perfectly implements “affordable living”. Apart from the low property costs, the private housing pioneer project has minimal construction costs of only € 1,270/m² gross floor area (ÖNORM B 1801-1)which is about 10% lower than the usual Viennese construction costs. Therefore,the project is exemplary for the fact that energy-efficient construction is not contradictory to social and affordable housing. Even though the project is implemented without housing subsidies, the students pay no more than 350 EUR per unit per month including all running costs.
High standard of comfort and design
Nevertheless, the best energetic standard – the passive house standard – could be realized for this project. Thus, energy efficiency is not a cost driver but rather ensures that residents benefit from constantly high living comforts due to ideal air quality and very low running costs – from the first day on.Moreover, the passive house standard including exterior sun shades guarantees comfortable temperatures even in summer.
Ecologic passive house
All modules are nogging piece constructions without chemical wood preservation.The entire insulation is made of mineral insulants. The totality of embodied energy could be reduced to a minimum for the entire building, as even the foundation is comprised only of reusable deep foundations which are again topped with a nogging piece construction rather than a concrete floor plate.
Minimum construction site logistics
In spite of the unique and spectacular ten special transports of the 5.5 meter wide and 16.8 meter long accommodation units, the entire project exhibits only minimal construction site transportation. Almost all companies and workers involved in the assembly of the accommodation units were from around Schwanenstadt, where the high-quality accommodation units were constructed “ready for occupation” in the construction hall of the renowned woodwork company Obermayr Holzkonstruktionen.
The Wohnbauvereinigung für Privatangestellte (WBV-GPA) in cooperation with the accommodation operators OeAD-Wohnraumverwaltungs GmbH and home4students - Österreichische Studentenförderungsstiftung are the developers of this project.The team of the of the PopUp dorms is including F2 Architekten ZT GmbH, Obermayr Holzkonstruktionen GmbH as well as Grünraum planen und bauen GmbH from Schwanenstadt, S&P climadesign GmbH from Ohlsdorf and LANG consulting from Vienna, impresses with competences regarding sustainable, energy-efficient building. Moreover, the latest innovation by J. Pichler Gesellschaft m.b.H.from Klagenfurt, energy-efficient and economical ventilation units for passive houses, provides coziness for interior rooms. The comfortably warm outer shell of the building was supplied by Saint-Gobain Isover.

Each of the twenty-two accommodation sections is completely self-sufficient and functional, and can be relocated to various properties five times within 40 years including their furniture. The ventilation system (one per box) can supply a whole module of 75m² independent of the use, whether if it is used for accommodating a group of 4 students or a family or even using it as an office.
Thanks to the intelligent low-tech-concept the whole HVACR of the building is using only 0.5 percent of the floor space. The new from Passive House Institute certified “all in one” heat pump multi-unit “System Ventech PKOM4classic” handles the functions ventilation, heating, cooling and hot water on an area of 0.75m². This reduction of space helped to keep the costs low.
The maximum heating capacity for air is 1300W, the maximum heating capacity for hot water is 1600W. Each ventilation unit delivers a total of 240m³/h, which is split in 120m³/h to the student rooms and 120m³/h to the atrium. The heat pump multi-unit supplies 1.2kW heat load per module, which is split in 800W heating through the air and 400W through convectors. Per module a hot water tank of 212 liters is included, in combination with water saving water taps.
The students and stakeholders are satisfied. Fresh and healthy indoor air quality is guaranteed 24 hours a day.
