Communal living in the House Falunred

IU International University of Applied Sciences

Idea projektu

House Falunred is being built as a communal, sustainable housing project on an undeveloped plot of land in the northeast of Mannheim's squares, the T6. A contemporary interpretation of the Phalanstère concept is being created. The aim is to develop a progressive, high-density, resource-efficient, and energy-self-sufficient form of living that enables working, producing, and living in a hybrid context. The architecture draws on the surrounding area with its red brick facades and fascias and reinterprets them using sustainable, regenerative building materials such as wood, clay, and cork.

Popis projektu

The Phalanstère concept is based on the principle of self-sufficiency in a self-functioning and viable space (community). The following conceptual ideas have been developed for the contemporary and urban planning (adaptations to property size and location) application of this idea.
INTEGRATION into the T6 by inviting neighbors to the café falunred.
PROVISION for the neighborhood and the building by the unpackaged store falunred. The most important groceries are always available.
EDUCATION for the children of T6 in the daycare center falunred. The eastern outdoor area belongs to the daycare center and thus offers the best lighting during the main care hours.
WORK SPACE in the building, whether it‘s bike repair and furniture building on the ground floor, or art creation and home office directly above.
CLEANING in the in-house laundromat. Washing together is more fun than washing alone.
RELAXATION in the in-house spa with pool and sauna. Here, stress is sweated away.
INTERACTION between residents in POINT, the communal cooking, dining, and recreation room. Billiards and table soccer provide entertainment.
LIVING in 39 apartments of various sizes; for singles and couples in one- or two-room apartments; families in multi-room apartments; singles and seniors in cluster apartments and students in shared apartments. Single parents are also supported here.

Greenery concept/biodiversity:
The renaturation of the urban space, here on the grounds of the house Falunred, is promoted by a sustainable greenery concept. Several plant species with different primary functions are combined to develop natural biodiversity. This measure is intended to benefit not only the Falunred, but also the entire T6 square and beyond. The development of the roofs, mostly as green roofs, as well as the generous renaturation of the remaining ground areas contribute to increasing resilience to heavy rainfall. In addition, the evaporative cooling effect of the vegetation improves resistance to heat and drought periods. Wall greenery consisting of various climbing plants primarily serves to create spatial quality (visual comfort), but also promotes improved air quality (olfactory comfort) as a CO₂ storage. Facade greenery consisting of further vines not only improves the microclimate, but also provides noise reduction (acoustic comfort) and shading (thermal comfort) for the building surfaces. The south facade in particular benefits from the shade, as it creates a more pleasant indoor climate. It is important to choose the right plants: wild vine flourishes better on the south facade, while the north facade is better suited to ivy and honeysuckle. It is also important to ensure that the plants are truly native.
Natural materials/circularity:
The building products intended for the house Falunred will mainly be sourced from natural and renewable resources. This means that materials containing harmful and hazardous substances can be largely avoided, and instead, the building can be constructed and used in a circular way. As a result, not only is the carbon footprint reduced compared to conventional reference buildings, but the indoor air quality is also improved, which is better for the health of the residents. The building's construction is based on consistent modularity, repetitive construction with wall elements, prefabricated wet room units, and timber frame construction. This enables planning based on the cradle-to-cradle principle. Prefabrication in the factory not only ensures higher quality of construction, but also simplifies assembly and disassembly in the factory, on the construction site, and at the end of the (first) use. Separating materials by type thus contributes to resource-saving reuse, recycling, or upcycling. Where possible, construction adhesives or glue are not used. Instead, techniques such as mechanical fastening of wood fiber insulation and connecting the planks in the stacked board ceilings or wall elements using wooden dowels ensure stability and connection.
These material-specific details offer high durability and circularity. In addition, air-dried clay bricks are used for interior construction, which, unlike fired clay bricks, are an energy-efficient and resource-saving alternative. This means that the clay bricks can be easily recycled and even reshaped after their first life cycle. At the same time, their moisture and odor-regulating properties and thermal storage capacity offer additional comfort for residents. The same applies to the floor structure. It consists solely of rammed clay with a linseed oil sealant (as well as floor temperature control) and cork impact sound insulation. The reduction in the number of layers and the simplicity of the details are intended to facilitate easy separation and avoid the production of hazardous waste.
Partial self-sufficiency:
The partial self-sufficiency of the house Falunred is a sustainability goal that is being pursued through various, partly independent concepts. One concept involves the efficient use of (rain)water and the creation of an ecological and economical water cycle system. With the help of decentralized water management, water treatment can take place locally in a gray water recycling system, saving valuable drinking water. In addition, a cistern can promote the natural water cycle by collecting rainwater and buffering it during heavy rainfall. The subsequent use of this water for garden irrigation or toilet flushing returns it to the natural cycle and reduces the consumption of additional drinking water. The sustainable greenery concept provides synergetic benefits for the natural water cycle on the property. Extensive roof vegetation ensures rainwater retention, while the green ground surfaces are beneficial for natural drainage. This ensures adequate groundwater recharge, but also protects against flooding. Evaporation from ground surfaces and through the foliage of the plants follows the natural water cycle. At the same time, thanks to the west winds and cross ventilation, it provides passive cooling of the interior spaces.
Another concept for promoting partial self-sufficiency is the contemporary reinterpretation of the Phalanstère concept as a communal living project. Instead of serving only one purpose (living) or only one social milieu, this concept is based on a functional and social mix of uses in eight categories. These include integration, provision, education, work space, cleaning, relaxation, interaction, and living. This heterogeneity is intended to focus life more strongly in the house Falunred and thus secure the existence of the house in the future. At the same time, it demonstrates the possibility of flexibility and adaptability to future (utility) changes.
If the house cannot offer something on site, it offers transportation to the destination instead. A low-emission mobility concept which, in addition to its proximity to public transport (tram and bus stop Gewerkschaftshaus approx. 200 m away) and public VRN next bike rental stations, relies on in-house car sharing and parking spaces for (cargo) bicycles in the basement. Charging stations will be available for electric cars and e-bikes, enabling emission-free travel even in old age.
However, emission-free energy for charging e-bikes requires a sustainable energy and heat generation concept. To achieve this, the installation of solar panels on the roofs is planned. The energy generated can either be used directly by the residents, collected in an electricity storage unit, used to charge electric cars and e-bikes, or made available for further technical operations. A brine/water heat pump can thus use renewable energy to operate active underfloor heating and passive cooling, as well as provide hot water. Verandas have been developed as sun protection for passive thermal insulation. These contribute to a reduction in summer heat gain and thus a reduction in cooling loads, while at the same time providing pleasant threshold spaces for social interaction.

The holistic combination of concepts and measures is intended to create a sustainable and future-proof house Falunred that meets ecological, economic, and socio-cultural developments.
