Vision

At the beginning of the project was the vision of an innovative and sustainable prefab house, which not only generates all the energy needed in-house from sustainable sources and that can be 100% recycled into the material cycle. The building should also create a link between the built environment and electromobility - and show ways of optimally coordinating energy generation and energy consumption at the local level through a smart grid.

Context

The prefab house is located at Bruckmannweg 10, in the heart of the famous Weissenhofsiedlung in Stuttgart. Built in 1927 within a few months, this settlement on the Killesberg was like a revolution in construction. The designs of various world-famous architects showed how we can build and live in the future. Parts of the Weissenhofsiedlung were destroyed and rebuilt after the war - except for the property in the Bruckmannweg, which lay fallow since 1945. Here, for a period of three years, appears B10, a new forward-looking building that shows how innovative materials, designs and technologies can sustainably improve our design environment.





Project

The research project - named "B10" after its location in Bruckmannweg 10 - is an active house. Thanks to a sophisticated energy concept and self-learning building control, it generates twice as much energy itself - from sustainable sources. With the surplus gained, two electric cars and the listed building of the architect Le Corbusier (since 2006 the home of the Weissenhof Museum) have been supplied. Upon completion of the research project, the prefab house will be completely dismantled, rebuilt elsewhere or 100% recycled. The property is then returned to the city of Stuttgart in its original condition.

In an initial phase of use, interested visitors can find out more about the energy concept and the applied construction technology in B10 prefab house. In the second phase of use, the building will be inhabited free of charge by two students. During the entire project period, energy generation and energy consumption as well as a large number of other highly relevant data for building research are continuously measured and scientifically evaluated at the University of Stuttgart.

Builder

The developer of the project is E-Lab Projekt GmbH, a project company of the non-profit Stuttgart Institute of Sustainability Foundation e.V. (SIS). SIS is a non-profit association. It supports and develops methods and technologies for sustainable construction. SIS combines science with industry and crafts. The association was founded in 2011 and has its headquarters in Stuttgart. Further information can be found at http://www.sis-stiftung.de/verein.php



Description from architects

Active House B10 is part of a research project examining how innovative materials, structural designs and technologies can improve our built-up world in a sustainable manner. Thanks to a sophisticated energy concept and a predictive, self-learning building control system the house generates twice as much energy from sustainable resources as it actually requires for its own needs.

The surplus energy is used to power two electric cars and – utilizing smart grid technology – the neighbouring house built by the architect Le Corbusier (home to the Weissenhof Museum since 2006). Combining mobile and permanent infrastructures is an extremely promising approach towards achieving an integrated and decentralized power supply to serve the needs of both electro-mobility and the built-up environment.

Throughout the entire life of the project the consumption and generation of energy as well as a large spectrum of data relevant to building research will be measured on a continual basis and scientifically evaluated at the Institute for Lightweight Structures and Conceptual Design (ILEK) of the University of Stuttgart.

B10 is part of a network of projects known as "Shop window LivingLab BWe mobile", in which some 40 projects are being promoted in the Stuttgart and Karlsruhe regions. The project is supported by the Federal Ministry of Transport and Digital Infrastructure in Berlin. The state capital Stuttgart has made available property belonging to the city for a period of three years to allow the project to be implemented.

The building plot is located in Bruckmannweg 10, which is in the heart of Stuttgart's famous Weissenhof Estate. In the 1920s the estate was a ground-breaking signal for essential improvements to our built-up environment. Located on the Killesberg hills Active House B10 is following the innovative character of the estate and transferring it to new realms – where real-estate and mobility are considered and designed as an integral unit.





B10 dovetails the energy systems of electro-mobility solutions and buildings to an overarching integral control system. As a consequence, it combines the charging infrastructure and the building services equipment to generate, store and manage energy in a central element – that in turn makes B10 the link between the user, building, vehicle and the smart grid.

As well as its energy efficiency the building offers important design innovations. B10 was planned and industrially prefabricated within a few months. It was then assembled on-site in just a day. The diverse constructive innovations of the building include, for example, the use of just 17 mm thick vacuum glazing in the form of a storey-high glazed front. Other important innovations include the installation of a prefabricated technology rack with a central cable harness, fold-down facade elements (that fulfil a dual function as a patio), a fully recyclable timber-and-textile wall construction et cetera.

As is the case with all research buildings designed by Werner Sobek, B10 requires a minimum of resources and is completely recyclable. As a consequence, it fulfils all of the requirements demanded by the Triple Zero standard: the building generates more energy than it needs itself (zero energy), it does not produce any emissions whatsoever (zero emissions) and it can be returned to the materials cycle without leaving behind any residual waste (zero waste).


Description from AlphaEOS AG and B10 Future Living Lab

The Aktivhaus B10 serves alphaEOS as an experimental prefab house for the testing of new technologies and as a showcase for the networking of buildings and electromobility. The term "active house" coined by Werner Sobek stands for buildings that generate more energy than they themselves need alone or in conjunction with others (in a so-called active house network). It stands for buildings that can actively react to changes in the external space or in the interior, if these affect the energetic performance of the building or the comfort of the users. With other buildings, energy producers, energy stores and energy consumers, active houses can form a self-organizing network with the goal of the greatest possible energy self-sufficiency.

A unique project

A house that generates twice as much energy from renewable sources as it needs for operation and intelligently provides the excess for electromobility and electricity - that was the vision of the B10 Active House. A challenge on the whole track and a project that has no equal.

For alphaEOS, however, the Aktivhaus B10 is more than just a research project. On the one hand, the extraordinary architecture and the prominent building site in the Stuttgart Weissenhofsiedlung attract visitors from all over the world. On the other hand, we and our customers are always inspired by this place. The prefab house is the perfect environment for meetings and workshops on building and living in the future. For us B10 is therefore a magical place, no matter who we meet here, it always opens a space for new exciting ideas.

The birthplace of the active house

As consortium leader of the research project, alphaEOS AG was instrumental in the implementation of the Aktivhaus vision and was able to make a major contribution to the successful completion and fulfillment of the vision through the ingenious alphaEOS system. The energy concept and the self-learning building management make it possible to provide energy not only to the B10 prefab house itself but also to an electric car and the UNESCO World Heritage Site of the architect Le Corbusier (now the Weissenhof Museum). In cooperation with the University of Stuttgart, the recorded data are scientifically evaluated and used for further development.

A laboratory for the future of living

Here we are testing new networking technologies and developing forward-looking, network-compatible energy management for prefab houses with Active House standard. The enormous demand for home automation has given us ample opportunity to test new and existing technologies. Today we can share this practical experience with our customers to implement innovative projects very effectively.



Insulation

Thanks to its ingenious energy concept and forward-looking control, the Aktivhaus »B10« at the Weissenhof in Stuttgart generates twice its own energy requirement from renewable sources. The required, highly efficient and yet slim prefab house envelope was made possible by the use of vacuum insulation. The insulation materials Vacuspeed and Vacupor from Porextherm were used. Vacuspeed XPS panels have 3 mm thin XPS laminations on both sides to protect them from film foil damage and to facilitate attachment of the insulation material. The insulation panels were installed in walls and ceilings of the prefab house. For floor insulation, however, the choice fell on the insulating element Vacupor TS-B2-S with a lamination of recycled impact sound insulation panels.
