Phytoremediation
natural cleansing of contaminated soil.
Phytoremediation is a method of rinsing and cleaning contaminated soil of a number of different toxins and metals.
Phytoremediation may be applied wherever the soil or static water environment has become polluted or is suffering ongoing chronic pollution. Contaminants such as metals, pesticides, solvents, explosives, and crude oil and its derivatives, have been mitigated in phytoremediation projects worldwide. Some plants are even able to remedy sites poluted with uranium, so expert on phytoremediation, plant physiologist Leon Kochian.

Many plants such as mustard plants, alpine pennycress, hemp, and pigweed have proven to be successful at hyperaccumulating contaminants at toxic waste sites, being able to contain different amounts of various types of toxic waste. The alpine pennycress is one of particular interest to this project, as it can hold high levels of zinc and cadmium and even thrives in areas with high doses of these metals in the ground. These plants can since be used for what is generally called ‘biomining’. The plants will be cut and baled after they’d taken in enough minerals, then they’d be burned and the ash sold as ore. Ashes of alpine pennycress grown on a high-zinc soil in Pennsylvania yielded 30 to 40 percent zinc—which is as high as high-grade ore.
add-on elements and ‘Plug & Play’
prefabricated, wood, removable, exchangable.
The big advantage of a working with
prefabricated elements in an ‘add-on’ system is that the different parts can be developed as you go. At the same time construction can start early as further elements will be added on as they are needed and/or finished. This also makes for a potential very interchangeable system where whole building parts or specific material parts can be removed, changed or added later in the process. This system seems very fitting for the project at Filmbyen, as there is a large demand for 4400 m2 that, however, are fairly unspecific - some of the area is used as workshop
spaces, but if other stakeholders would demand specific instalation or spaces in their rental units, this add-on method of dealing with the spaces and building parts can help cover that demand. The architectural studio “Vandkunsten” just won first prize in a competition about the ‘sustainable house of tomorrow’, that uses a timber frame construction that is since filled in with a wall build-up, referring strongly to a half-timbered house. It is in an indirect way a plug-&-play system, as the proposal encourages renewing materials as they become obsolete

wind energy
renewable power in an urban environment.
a windbelt produces energy by exploiting
prototype that presents anoter way of producing energy through wind. It was developed at the TU Delft. The big advantages of the Ewicon is that it has no moving parts as it works with charged particles and a tension in the electrical field within the turbine.
Prototypes of the device are claimed to be 10 - 30 times more efficient than small wind turbines and a lot cheaper. However, there is currently no large scale plant that produces energy on a household level or higher. There is also a noise issue when working with large scale ‘vibrating’ windbelts. the EWICON is a bladeless wind turbine
Since it is noise less and modular scaleable, it seems very fitting for the urban context. Because the turbine is reliant on a specific form to work (though some shapes are more optimal than other) it can be transformed to fit a facade or by itself.
the motion of a string that is produced by what is called aerolastic flutter - essentially wind moves over a string and creates a vibration in the string, like you could imagine a blade of grass held between your fingers.

wooden construction & visible instalations
Accesible, construction, transformable.
wooden joinery can be translated into the
modern era in a number of ways, examples here of could include using prefabricated elements, lasercut or cut on a CNC drill, and then assembled at site. It is an important to emphasize that the main construction is wood.
A big advantage with this way of constructing a building is that large parts of the building can be constructed elsewhere, while foundation work and thelike are already established on site. When the prefabricated elements arrived, the rest of the building can be errected quite effectively.
Another advantage is the possibilty for disassambly and reuse of building parts and construction timber and/or steel fitted together in this way. The addition of making installations visible and easy to reach, is another step towards making the building easy to maintain and exchange obsolete technology as we go. The wirering, pipes and sockets is intended to become a clear visual element in the building, without being messy. It should be understood how the building is fitted together, so it makes the most sense for the user, the maintanence crew and any future involved parties, all the way to the deconstruction team.

rainwater collection and gray water reuse
rainwater, reusing, visible functions, green habitats.
Rainwater harvesting is the
accumulation and deposition of rainwater for reuse on-site. Uses include water for garden, water for livestock, water for irrigation and indoor heating for houses etc. When rinsed the water can even be used as drinking water. It is especially fitting for the side at Filmbyen as the contaminated soil will eventually contaminate the water as well. The point is to hold the clean water in the internal system for as long as possible in order to get the maximum value out of this free resource.
12
To do this, reuse of gray water should also be implemented. There is less gray water in a structure like this, compared to the same amount of squaremeters in a domestic property, but with implementation of showers, toilets, workshops and additional water using features, the reuse and recycling of the water will be important. It does not at the time seem like a possibility to establish an open water reservoir due to the contaminated soil, but it might a possibilty in the future due to the established phytoremediation.

general summary - Keywords Wood-based building system
The main innovation is to almost exclusively use a wooden construction. As Vandkunsten, the CO2 optimized Woodstock system is suggested. To keep it pure wood the building heights are held under 12 m (fire regulations) and all the spans are not over 8m (construction system). Point foundations
In order to minimize the impact on the site, point foundation are either screwed- or hammered into the soil in the necessary points. The consequence of this is that the building is ‘lifted’ a bit from the ground, but this can be seen as a quality, not a bad thing. creation of inner courtyard building mass optimized to sunlight and wind on site
Double programming
If spaces can be used for more than one function, we can save material, heating, maintaining etc. add-on system with prefabricated rooms / spaces
To use as little resources as possible, a lot of the elements, from details to whole conference rooms, will be constructed as prefabricated elements. These can be added on to the construction as they are done and/ or needed. visible installations
Easily accessible and replaceable as they become obsolete. green roofs
In order to use as little energy as possible in the building, it is very important to use the ‘free resources’ on site as well as possible. Thermal mass, natural ventilated spaces, intelligent placement of openings and spaces.
Water re-use and harvesting
natural movement through site (openings through building mass)
See Add-on system and visible installations. It is important that the materials are not destroyed as they are used. We wont to re-use directly, not downgrade our existing materials and the energy they embody.
rammed earth as thermal mass Establishing phytoremidiation
To cleanse the soil and add value to the site. An urge to let the grown environment have space to be more ‘wild’ in the area. expanding natural habitats
It is not realistic to recreate any nature that ‘used to be there’. But it is possible to establish new habitats for plants, animals, bacteria, mushrooms, trees & people. Green roofs and phytoremediation programs add to this, but it is necessary to keep it in mind in the building design as well.
Water harvested from the roofs, kept in tanks inside the climate space. Used for watering, toilet flushing, heating. Design for disassembly
‘filmbyen’ not ‘filmbygningen’
Maintain architectural, social, human diversity and diversity in flora and fauna on site. Spread the program out and make it possible to add on later instead of making one big ‘packaged solution’. connect to the harbour and let the proposed recreational route run optimally through the site

proposed materiale palette, municipality A palatte of materials is set for the newbuild. These are illustrated below. According to the local plan: “The newbuild must not use reflective materials in the facade that can be a nuisance for the neighbours.

Roofs must be clad with roofing membrane or zink - like surrounding buildings. Flat roofed proposals may have green roofs. Roofs must be plane, apart from the portrusion of circulation shafts, roof lights and possible installation of photovoltaic panels.�

proposed materiale palette, project In a number of points the projects differs from the local plan in regards to choice of materials - the proposed materials in the local plan are not great from a sustainability and/or re-use perspective.
wood is the main constructive material
Rammed Earth is proposed as a thermal mass in the building. It is a cheap material, easily constructed and disassembled (both can be done with man-power) and used correctly, the thermal mass of rammed earth can delay heat flow through the building envelope by as much as 10 to 12 hours.
building in order to expand biodiversity on the site and can also function as a part in a water-harvesting system. The extend and depth of the roof is not yet determined.
In cool or cold climates well-located rammed earth walls (e.g. feature walls within a well-insulated envelope) can supply useful thermal storage.

ZINC is not the worst roofing material and
it is one of the proposed materials by the municipality. Zinc can be re-used to 95% or even directly as a building part again. Zinc can be exposed to ‘sour’ air in industrial areas, but it is not sure that this will be a problem.
