Greetings from Prof. Köster about Solar Decathlon Europe 2021/22

Dear readers,

The ‘energy transition’ is one of the greatest challenges of our time. Public discourse, has pri- marily focused on the topics of transportation and power generation. Largely ignored; however, is the fact that these ambitious goals are seriously jeopardized by a modernization backlog in the area of energy-efficient building refurbishment. A real energy transition cannot proceed if the energy efficiency of existing buildings is not significantly improved. In the European Uni- on, 40 percent of energy consumption results from existing buildings - so there is still a consi- derable amount of potential in this sector for the future.

Solar Decathlon Europe 2021/22, an international university competition for sustainable building and urban environments, is all about intelligent solutions for the future. 18 university teams from eleven countries plan, build and operate sustainable houses. The Rosenheim team „levelup“ wants to build on the past success of our university in 2010, when we took second place in this global competition. Then as now, the recipe for success lies in many inquisitive minds and a healthy mix of visionary foresight, engineering expertise, creativity, and drive.

On behalf of the Rosenheim university family, I wish the team much success for the competition. At the same time, I would like to thank all participants for their outstanding commitment, which exemplifies the high innovative strength of the university.

Prof. Heinrich Köster With the kindest regards, President of the TH Rosenheim Prof. Heinrich Köster

2 3 greetings from the patron

Participation of the TH Rosenheim on the Solar Decathlon Europe 21/22

Sustainability is one of the guiding principles of Bavarian politics – which naturally also carries over to the energy sector. For example, in recent years Bavaria has enormously increased its share of renewable energies by using mass electricity generation. We have reached over 48 percent with this endeavour. Our goal is to make Bavaria the first climate-neutral state in Germany.

Increasing the share of renewable energies even further; however, means that we cannot rely on restrictions, but on new technologies and innovations. Which, to a very large extent, come from our Bavarian universities.

Because 40 percent of Germany‘s total final energy consumption can be contributed to buildings, the focus on sustainable construction and housing has greatly increased.

Therefore I am very pleased that the TH Rosenheim, with its innovative faculty and student team, is participating in the Solar Decathlon Europe for the second time. By doing so, TH Ro- senheim enormously contributes to increasing the level of innovation in the building sector, which in turn also strengthens Bavaria as a technology hub.

I wish all participants at the TH Rosenheim, who are involved in this future-oriented project, much joy and success. I am positive th Klaus Stöttner at you will present outstanding, sustainable solutions for modern construction in urban areas. Member of the Bavarian State Parliament 1. Chairman of the Board of Trustees Sincerely of the TH Rosenheim Klaus Stöttner

The teams not only develop designs, but also implement them in the form of a fully functional prototype on a 1:1 scale. At the end of the project, the teams will compete against each other in ten disciplines at the exhibition in Wuppertal over a period of two weeks. The fully functional house demonstration units are open to visitors at the exhibition in Wuppertal in June 2022. The Rosenheim team‘s building must convince the jury not only in terms of comfort, technology and sustainability, but also with its innovative approach to the concept. The goal of the competition is to raise public awareness of real-life solutions for the energy transition, the creation of affordable housing and energy-efficient construction using renewable energies.

10 11 our vision

levelup ... your building

Cost-effective addition of stories using prefabricated, standardized, wood construction elements with attractive architecture. The innovative und barrier-free interior offers many conveniences and high func- tionality.

levelup ... your sustainability

Within the framework of holistic planning, the individual planning components that address sustainability are interlinked. Natural resources and ecosystems must be protected and the health and well-being of animals, humans, flora and fauna must be improved.

levelup ... your comfort

For the provision of indoor comfort, climatic conditions and functiona- lity are vital to increase the personal well-being of the occupants and their user satisfaction.

levelup ... your technology

The challenge is to find the most efficient energy concept in order to realize a carbon neutral building with a low level of energy demand. This will be accomplished by the use of photovoltaic and solar thermal systems, intelligent building automation and other innovative systems.

levelup ... your community

Residents in different phases of life live together and form a community that supports each other by sharing services and goods. Green community areas on the roof and sharing concepts strengthen the feeling between neighbours.

Team‘s Organisation and Objectives

The Solar Decathlon Europe (SDE) competition at the TH Rosenheim is currently being driven forward by an interdisciplinary team of students, from various courses of study and faculties, with over 20 advising professors at their side. Our levelup team is also supported and sponso- red by numerous industry, business, research partners, organisations, and individuals. Coming from specific disciplines, twelve student team leaders supervise larger groups of student teams that, in turn, cover major topics areas required by this comprehensive completion. Interdisci- plinary teamwork enables very detailed and extensive work processes, and facilitates communication between faculties. levelup will create practical, innovative, and future-oriented solutions for affordable and climate-friendly housing in cities and communities. Existing building stock is abundant in urban environments in Germany, and for this reason, we are developing renovation solutions based on these existing structures. The premise is not to demolish, but to reuse what already exists. By adding additional stories onto existing residential buildings, we can “level up” their functiona- lity by increasing and improving living space. Because the majority of these existing buildings were built between the 1950s and the 1970s, we need to achieve high synergies by making sure that addition of storeys are adaptable to various floor plan types of all periods of construction. Vertical, two-storey extensions can be achieved with a modular timber construction, which is detached from the statics of the existing building. Prefabrication of the modular elements will reduce construction time and keep costs to a minimum. By using sustainable, energy-efficient, and socially acceptable architecture to advance the energy transition in urban neighbourhoods and create sustainable cities, our objectives align 100% with the goals set out by the United Nations (UN), the European Commission (EC), the Federal Government of Germany (BRD), and the Free State of Bavaria. More specifically, the Sustainable Development Goals (SDGs) of the UN, namely no. 11 Sustainable Cities and Com- munities, the EC Mission, Climate-neutral and Smart Cities, and the objectives of the New Euro- pean Bauhaus, the National Sustainable Development Strategy of the BRD, and the Bavarian Bioeconomy Strategy, all correlate to the objectives of the levelup project and our team. We are planning with renewable, biogenic, CO2 absorbing building components like wood and recycled materials, because it has been estimated that buildings produce over a third of all greenhouse gas (GHG) emissions worldwide.

18 19 This made it possible to bring more interdisciplinary students into the team, coming from different courses of study and faculties, and to integrate their knowledge into the project. The first submission design, called DEL#1, was broken down into individual focal points, called deliver- ables, which were then further developed and elaborated by relevant faculties. During the following summer semester of 2020, the levelup team was expanded even further to include additional professional disciplines and faculties required by the competition. Tech- nical components dealing with energy and building technology were thoroughly investigated by various student teams, and were incorporated with the initial designs from the first delivery. Meanwhile, a team focusing on neighbourhood integration evaluated the levelup design in a holistic context by uniting concepts dealing with urban transport and the future of mobility.

The levelup team contacted the Nuremberg Municipal Housing Association or “Sied- lungswerke”, because they have the appropriate real estate at their disposal for this purpose. In addition, there is great interest in adding storeys to the building after the competition on the basis of de designs created there. Despite COVID-19 pandemic restrictions, the levelup teams intensively communicated with their consulting professors via the internet.

House Description and Relevant Items

As an addition to the storeys of an existing apartment building, the system can be adapted to a wide variety of buildings that correspond to the building and floor plan typologies of residential buildings from the 1950s to 1970s. This creates an innovative solution for redensification in cities, which can be applied to the largest proportion of the German building stock of multi-family houses. The SDE21 competition entry will be developed on the basis of an existing building in Nuremberg, that exhibits the building and floor plan typologies described. The extension to the existing building comprises two levels of extension, which includes private living space as well as communal common areas and utility rooms that serve as basement and attic compensation.

The modules of the system are planned with a high degree of prefabrication in innovative timber construction, so that all elements can be dismantled and recycled according to the Cradle to Cradle® principle. This makes it possible to react individually to the existing situation at each location and to create new, innovative living space that is needed on site. At the same time, the system can react flexibly to the needs of the residents and serve every age and target group without restrictions. The integration of flexible rooms, some of which are located between the individual residential units, enables the desired flexibility. The flexible as well as connectable rooms can be used as a separate living unit or divided among the neighboring apartments, gai- Figure 2: modular addition of storeys, © levelup I SDE21/22 ning additional living space, which allows the apartments to be enlarged. With its expressive, visionary architecture, the levelup system stands out from the existing building and at the same time forms a unit with it through the redesign and the renovation of the existing façade. The extension, makes a statement. It does not try to hide in the monotonous image of the residential buildings, but arouses the interest of passers-by through its prominence. This is not only to draw attention to the levelup system in timber modular construction and the associated type of redensification in the city, but the architecture also draws attention to the issue of sustainability in the neighborhood.

The House Demonstration Unit illustrates the entire Design Challenge addition in Nuremberg. Three modules are „cut out“ of the cubature of the extension with its gable roofs. The new vo- lume of the HDU results from the chosen cutting lines. This includes, in addition to the three residential modules on the first floor, the derived representation of the common areas of the extension on the upper floor in the form of a roof terrace and a winter garden.
