PROJECT summary - Keywords Wood-based building system
The main innovation is to almost exclusively use a wooden construction. A beam and column construction supported by the Thoma ‘Holz100’ building system is the building structure. To keep the buildings in pure wood the building heights are held under 12 m, with the top floor being less than 9.3m from the ground (fire regulations) and all the spans are not over 8m (construction system).
Double programming
Spaces are used for more than one function, in order to save material, heating, maintainence etc. add-on system with prefabricated rooms / spaces
Point foundations
In order to minimize the impact on the site, point foundation are screwd into the soil. These can be removed after the lifespan of the building
To use as little resources as possible, a lot of the elements, (windows, decks, walls) will be constructed as prefabricated elements. These can be added on to the construction as they are done and/or needed.
creation of inner courtyard
visible installations
In order to create the highest quality of outdoor spaces on sight, two buildings are placed on site, in order to minimize wind. building mass optimized to sunlight and wind on site
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. natural movement through site Establishing phytoremidiation
To cleanse the soil and add value to the site, willow is planted beneath the green roof. These willow basins can utilize the extra rainwater all while they clean the soil underneath. 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,
8
bacteria, mushrooms, trees & people. Green roofs, willow basins and a placement of programs and parking that still allows for more or less ungroomed nature support this cause.
Easily accessible and replaceable as they become obsolete. green roof Design for disassembly
See Add-on system and visible installations. It is important that the materials are not destroyed as they are used. We want to re-use directly, not downgrade our existing materials and the energy they embody. ‘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
Local plan VIOLATIONS Materials: As seen on the next two pages,
the project uses radically different materials than what is suggested in the local plan. This could however be dispensated for, as the local area consist of a broad range of building materials and facades, and this project only would support this more or less messy (but very charming) expression that can be seen as a quality to the site.
Parking: There are 300 parking spaces in
the project, which is also the number the local plan wants to meet. The same is true for bicycle parking. River & recreational route: The river
placement: The local plan suggests a
placement of two six story buildings with gabels facing towards the harbour. This project is more concerned about creating the best spaces for people than it is about the symmetry on site. This means that the buildings are placed in a way, that makes a wind free courtyard as well as create a great view towards the harbour for as many people as possible. This is probably the biggest violation on the local plan, and will probably need a rewriting of the local plan to become a possible building project.
suggested in the local plan, is not respected in this project, as it is not seen as a realistic future player on site. The suggested recreational route is suggested to run through the existing Filmbyen building, and this route is respected. However, a more likely outcome is that people will walk around the gable, and this is the reason the building corners are held free in order to welcome pedestrian and bicyclists traveling along the scenic route.

proposed materiale palette, municipality A palatte of materials is set for the new buildings on site. 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.
10
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.�

material strategy
wood, mechanical, disassembly.
Two building, one building system.
The decision to have two building is a result of contextual thoughts, but the building system remains the same in both buildings, both regarding the structural system, window strategy etc, as elaborated in this folder. The main differences between the two are FLOOR HEIGHTS and the GREEN ROOF on the main building. in addition to the Holz100 elements, cross laminated timber are used for the trusses and a structural beam and colum grid for structural support.
32
â&#x20AC;&#x153;Every board, beam, pipe and fastener going into the Bullitt Center must meet a strict set of guidelines established by the LBC to ensure that the building is constructed of materials that cause minimal harm to the land, air, water and people during the extraction, harvesting, processing, manufacturing, and transportation of that material.â&#x20AC;? BullittCenter.org
The project is an attempt to design as much for disassembly as possible (and, as a result, also designed to be quickly erected and easy to maintain). As a result of this there is used no concrete in the project, as of now. This results in a more experimental foundation consisting of screw-piles and a steel frame.
thoma ‘holz 100’ wood elements
pressed natural straw, structural and insulating
‘Holz 100’ is pure solid wood, untreated and free of toxic chemicals. Walls are left free from mould and condensation. The unique wooden-dowelled cross laminated construction results in no air leaks, no shrinkage and no thermal bridges.
Walls, ceilings and roofs can be made in thicknesses from 12 to 40cm and the elements are prefabricated with CNC milling and quickly assembled on site. The elements consist of layers of FSC certified wood that are connected mechanically instead of chemically, which means no glue or preservatives. Holz 100 provides very good insulation due to the thin layers of air between each layer of wood, and no aditional insulation is needed.
The Holz100 40cm thick thermo-wall has a certified thermal conducting co-efficient of 0.079W/mK which is a world record among all structural building materials. The wood is breathable and to keep as much of the woods natural abilities, no vapor barriers are used together with the wood panels in this project. Additionally the Holz 100 elements have very good abilities regarding fire concerns (Thoma Holz100 40cm thick wall: REI 120 minutes, or F90 fire resistance) and acoustics. (http://www.thoma.at)

The slanted green roof is tilted at an Angle of 52* degrees, which makes a ‘standard’ construction of a green roof difficult. It is necessary to have a layer of ‘Geocells’ that can hold the earth and on top of which the sedum will be placed. The roof construction is explained in detail in the 1:20 section.
38
The roof can support sedum, mosses & herbs. The roof will hold some water and release it more slowly than a non-green roof. The roof holds organic material and will contribute to the bio-diversity in the area.

staircase strategy
removable, simple, wood, steel.
the staircases both inside and outside of the building will mainly be comprised of steel. Outdoors the escape route staircases
will be made of galvanized steel and steel grating for the steps, without any risers. These staircases will be easily removable and can be used in order buildings after the lifespan of the project. The staircases will be delivered ready to the site and are easily mounted and require little maintenance.
42
indoors the staircases will be steel girders
with wooden steps. These are easy to maintain and can be used in a number of different building after the lifespan of the project.
Window strategy
full size standardized, Hidden frame, plug and play.
windows in the two buildings will
mainly be full sized windows that stretches from one column to the next (3700mm). In selected places the full frame windows will be replaced by cut windows with mullions in order to make openable windows. (see reference below) Towards the courtyard, the slanted green roof will provide protection from the south sun in order to reduce the necessity for
cooling the building. In strategic places the green roof is penetrated to make room for meeting spaces. Through these meeting rooms the offices are also provided with warmer sunlight from the south, but in a controled manner. The window frames are placed in a manner that they are hidden from the inside but can still easily be removed from the outside. (Detailed in 1:20 section)
