Material research
The project took off by researching many different materials with different properties.
There were a few different criterias for researching materials at the beginning of the assignment. Some should be representing traditional building materials, like cellulose insulation and concrete. Some should be more unconventional, like cardboard and some should be unexpected like growing buildings. Some inovative production processes where researched as well.

Grasshopper & Projects Creating tools to make parametric models of existing projects
Three projects where re-made by programming different tools in grasshopper to make the models parametric. They were chosen from different architectural categories and because of a great difference in what digital tools they would need. The projects where FabLab House, Jellyfish House and R128. FabLab House is a previous Solar Decathlon building, thus solar energy income was an important factor to deal with in the grasshopper script. The Jellyfish House is an experimental competition that handles a lot of complex systems within its building envelop and the script needed to interpret this complexity. R128 by Werner Sobek is a good example on a modern modular housing with lots of nicely solved energy systems.

Jellyfish house
[ ] RAINWATER
Is cApTuREd & fIlTEREd by ThE ExTERIoR lAyER
By Ivamotoscott Architects
The Jellyfish House is pretty much an empty envelop. But the interesting part is what happens within this envelop and how it works without any interaction from its users. It acts both as a protecting physical cover and also as an active smart technology that remediates its own environment. Just like the jellyfish the building is symbiotically integrated with the ecological processes of its site. The skin of the building consist of a mesh that captures, filters and stores rain water so that the inhabitants can use it. It is first lead to cavities where UV light filament purifies it, powered by thin PVfilm. To protect the inhabitants from the harmful UV rays, the cavities are coated with titanium dioxide that filters it. Moreover the skin has fluid-filled pockets with a phase change material that act as a latent heating and cooling system. Worth mentioning is also that the house is a future vision, that should be feasible to construct within 25-50 years.

By Werner Sobek i-bEAM
MoRTicE-TEno EASy ASSEMbL
The R128 house was the first building to meet the requirements of the triple zero standard. It was designed to be completely recyclable with no emissions and to be self-sufficient in terms of heating and energy consumption. The building is completely glazed with high insulating triple glazing panels. To meet the energy requirements the heat energy radiated into the building is absorbed by water filled floor elements. The water is stored in a reservoir which is used to heat the house in the winter by reversing the exchange process. The electrical energy required for the energy concept is produced by pv-cells on the roof. All the energy systems are computer controlled to optimize performance and allow the system to be remote controlled. The load bearing structure consists of a steel frame stiffened by diagonal steel wires. The design is modular without composites and the structure is assembled with mortice-tenon joints and bolts. This makes the structure easy to assemble, disassemble and recycle.

Conclusions
Experience from the three projects and collective reference database.
There were many things from the projects that influenced the outcome of the final competition project. From modular frame system in the facade, to an active building envelop and ideas about how to gain as much solar energy as possible. Tools where developed to understand complexity in structural elements and solar gain.

Urban implications The urban forest
Urban agriculture seem to be a more sustainable way of growing food than our industrial agriculture; it reduce our consumption patterns, make people increase their resource efficiency, work as a closed loop system, and use the direct and indirect energy from the sun in a resource effective way. Right now the disadvantages or problems with this kind of farming are that it often needs to be complemented with products from the large scale agriculture, that there are health risks from using contaminated water, or growing on contaminated soil. But with proper control integrated in a simple way in our society i believe these problems will be dealt with. With protection against cold, like greenhouses, the urban agriculture can become even more effective and produce more food and thus replace large scale agriculture even more. Hopefully we can see that the numerous positive benefits, like sustainability, improved health and happiness, is enough to transition into a society where urban agriculture is a natural part, instead of use it only in times of crisis.

Building Principles
Basic principles & logic behind the design of the building
Water system
Rainwater is purified along the green walls, and doesn’t run off as quickly as normal. The water also gets collected in a water buffer tank. This water can then be used for showers and sinks and is later purified again via the facade.
24
Ventilation system
The southern wall acts as a trombe wall when heated; it makes air cirkulate and heat it within the building envelop. During summer or whenever cooling is needed the house instead act as a solar chimney, with air beeing cooled by thermal mass at the north facade.

Interior system
A part of the load carrying structure morphs in certain places to create furniture and spatial qualities. It also lets the inhabitants have plenty of space for storage. This organic shape makes the interior more soft and toghether with the floor heating from the water tank it feels nice and warm.
Exterior principles
The lower part of the southern facade is dedicated to growing your own vegetables! they are easily reached and are slided into the facade so they can be removed at any time. Evapourative cooling from the green facade is also one important feature during hot summer days.

Translucent skin
the top 60% of the facade is used for pv-arrays on top of a transparent wall system. The translucent wall lets in daylight while keeping privacy towards your neighbours.
Growing skin
the bottom part of the facade is used for plant boxes, adding green area on narrow plots.
A-frame structure
the load bearing structure is built like a regular A-frame roof truss. Simple and flexible elements that can be adjusted to fit the triangular shapes.
Egg-crate interior
the interior structure shades the sun in the summer and integrates interior parts and furniture into the wall. The egg-crate structure is cnc-cut from recycled cardboard sheets.

Solar radiation
around 60% of the southern facade can be used efficiently even during the colder seasons when more energy is needed. The rest of the wall can be used for vegetation. The building volumes can be placed with a spacing of 7 m in beetween without shading each other.

city scenario
Implemantation of the Seed in a city
New city scape adding green
high rise buildings with flat rooftops gets a new appealing silhouette. By putting the building on the rooftop we give back green space to the city .
Adaptable shape
Purifies and collects rainwater, cools the city and reduce the urban heat island effect. For the neighbouring situation there are 3 main scenarios for the house placement-the roof tops,as an addition to existing building and as a floating house. Concerning the water implementation, the units are placed on floating rectangular bases that are connected with the shore.
New temporarily land usage
the houses can be placed in sensitive environments and polluted plots to purify the soil and water.
Reducing the urban heat island effect
Little vegetation or evaporation causes cities to remain warmer than the surrounding countryside Heat energy radiates from the urban areas,the green areas disband the heat accumulation ,green walls,green roofs and parklands absorb heat and cool the urban atmosphere

Locally produced food
Flowers with yellow,blue and purple colour attract bees Mints,Lavenders
Lichens and alga is a symbiont in this parternship, providing through photosynthesis the nutrients the fungus needs to live. Sometimes the symbiont is a cyanobacterium, as in the case of the lettuce longwurt, which pulls nitrogen directly from the air and is a source of natural fertilizer for trees. Bats provide the city many benefits: they eat insects and mosquitoes.
minimizing the need for imported food and transportations
Increased equality
when you can control what you eat and how much to eat you get less dependent on stores and prices. This leads to increased independence and equality.
Biodiversity
insects ,birds and urban bats can immigrate back to the city where they once lived.

ownership
The houses placed in the community can have different sizes, fitting up to 5 habitants and can have the interior adapted for the family’s necessities. The habitants can vary and the community shape makes the living beneficial for a big range of ages. For kids for example, can have a close contact with the green, experience how to grow their own food, and discover nature without warring about traffic and other city barriers to the green.
gardens ownership ROOFTOP COMMUNNITY SHARED GARDEN The shared gardens between the neighborhoods are important to promote production commuting. Since the houses differ on their solar orientation the vegetable growth will vary. The vegetable commuting promote social interaction between the neighbors.
SEED 2.0 OWNER’S PRIVATE GARDEN The owners of each house can grow their favorite vegetables in their private garden. Special herbs and medicinal plants needs may vary between different house habitants, therefore an area where they can choose what they prefer to have.
BUILDING HABITANTS SHARED GARDEN In this communal space, the habitants share the responsibilities and the garden production. This area is also where the goat stays and where the community can come together in social or work mingles.
Meeting points The meeting points can be set in between the houses, and they can differ according to the community preferences, but the areas could have barbecue places, game tables, kids playground or whichever activity suits better the inhabitants.
rooftop urban farming “SHARED” GOAT The community can benefit from a “shared”goat in many ways. Goats are friendly animals that can easily adapt in different situations and habitats. Their demands are low, a dry place to sleep, to be milked twice a day and be walked 3 times per week. They also produce compost that can be used to fertilize the home gardens.
URBAN BEEKEEPING Incorporating the beehives into the Seed 2.0’s community brings out a full range of benefits. Besides producing honey and wax, the bees pollinate the garden’s fruits and vegetables in the area, potentializing the house’s farming walls.
BAT HOUSES The bats are great allies for plant’s growth and reproduction. They eat unwanted insects that could harm the plants and also undesirable animals such as mosquitoes, which disturb the humans. They excrement is a great plant fertilizer. Like the bees, they work as important pollinators.

How it works and what it does on the site
The site situattion illustrated on this poster shows how the house volume would look placed in the Solar Village, the Solar Decathlon Competition site in Versailles, France. structure is placed in the plot minding the boundaries set by the competition, is completely weelchair accessible. The house is perfectly placed to get the maximum optimization of the facades and also to give the visitors the best view of the design. While the exterior has a sharp and straight feeling, the design of the interior is more soft and inviting. The load carrying structure morphs in certain places to create furniture and spatial qualities and integrates technical equipment. Through the upper parts of this structure indirect sunlight is shining through and makes the interior bright without getting too warm.

plan
The flowing curves of the internal wall structure leads seamlesly from the entrance area through the livingroom to the kitchen. From here two doors gives you access to the hotbed and the garden and a coridor gives you access to the bathroom and bedroom situated in the more private areas of the house. All the technical equipment and storage is integrated into the wallstructure.
52
section A-a
The hotbed is situated underneath the the stair thet leads up to the loft. The stair also acts as an aditional seating area creating the heart of the house, the livingroom.
section B-B
The loft takes full advantage of the remarkabel ceiling height (7 Meters) creating a more private space in the otherwise very social and open planed building.
53
Passive ventilation
The main concept is to create an efficient and durable passive system that is based on thermodynamic principles.

solar study
Facade insolatoion and daylight simulation
The steep angle and the slightly bent shape of the building envelop ensures that the solar energy is harvested all year around. The placement of PV panels along the facade are optimized for the worst scenario, the winter sun, but also works well during the rest of the year. In that way more energy is produced when needed. The design of the building is an iterative process where the building model is analysed in different programs like Ecotect and Diva and the feedback is a direct input for further development of the 3D model. In that way the energy income, placement ov PV cells and costs can be optimized.
