Minimize, Maximize or Balance: Designing for Net Zero on an Urban Site (WED, 6/14)

Pop Up Dorms

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 dorm can move.

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.

Built and ready for occupation in no time
After the submission of building plans in January 2015 and a 2-month fabrication 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.

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 “GreenFlexStudios”, 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 – after all, the team is made up of members of the “Passivhaus Austria." 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.
