Design project introduction This design project aims to design a new ‘New Forest’ fungi forest park by reusing a post-Fawley oil refinery site, where the picking area and tanks in this area are designed in detail as the background of technical studies.

The site is belonging to the industry strip, which is bordered by the New Forest national park eastern area and Southampton water ria. This industry strip is proposed to be naturally recovered through the forest extension and be re-included into the region of New Forest national park, back to its original forest territory in my brief, forming new ‘New Forest’ forest park in the future.

Technical study topic The technology studies in this design project is focusing on mushroom cultivation in the oil tank facilities and the methed to create specific microclimate especially vapour, to help achieve the function and experience of mushroom picking area and tanks for picking purpose in the design project. This picking area and its 19 tanks includes three functions and three types of design, where picking tanks as main buildings with maximum proportion in this region.

Following the key study question, only the tank reuse strategy related to the cultivation and microclimate will be analyzed in detail in this journal rather than introduce all reuse strategies, in order to not focus on too many aspects.

The structure is divided into three main parts: first is general reuse strategy of original tank as a general guidance; second is mushroom cultivation microclimate criteria and strategy; third is the detail technologies of cultivation and microclimate based on the tank facilities, as the detail explaination of first and second part.

Part I

Tank and general reuse strategy In the first part, general tank reuse strategies base on the original tank structure in the picking area will be introduced, as the starting point to exlpore the part II microclimate and Part III detail technologies. As the research process, the tank original structure and precedent that inspire the thiking of reuse strategy will be also studied in this part.

Oil tanks are the major facilities in the whole park site, including reaction tank (right top)and storage tank(right bottom).There are 330 storage tanks at Fawley Oil Refinery large site and 19 storage tanks in the picking area site, as the major reused facilities for mushroom cultivation.

The storage tanks closed to the central facilities contained crude oil. Those in other locations contains intermediate products obtained from the refining and processing of crude oil. they keeps these intermediate products warm and liquid until they are ready to be further refined or used in chemical manufacturing processes.

The precedent, Mapo Oil Tank Culture Park, was used as oil storage for 41 years, before the tanks were reborn into a culture complex. The five tanks were transformed into performance halls, exhibition halls, and a multi-purpose pavilion.

The library and exhibition hall are majorly studied. Their strategies are adding new spaces and new floors to achieve the new functions, and also add new structure and building walls to support the thin tank skin and create a comfortable interior space for human, which could not be achieved by original tank skin.

In my project, the tank skin would be erosed in the future surrounding by the landscape in this picking area. The new structure and wall should be also added to support tank skin and create microclimate for mushroon cultivation. The detail reuse strategy are shown in the next page.

Part I conclusion

Tank and general reuse strategy This part gives a general study and strategically thinking on the tanks in the picking area, as the foundation to continue the following microclimate and detail technology study.

Being inspired by the Mapo Oil Tank Culture Park, the general reuse strategies are adding new walls and new structure to support the most of reused original roof and tank wall as well as part of the tank floor, which would be gragually erosed in the future. The new wall have a distance with original tank skin is to leave a corridor space with original tank roof, wall and floor to experience walking in the tank.

Part II Cultivation microclimate

Four important elements area necessary for mushroom growing:

30

Mushroom should be kept out of direct sunlight, but also not necessarily need a dark environment.Because mushrooms cannot extract nutrients from the sun as green plants do.

The advantage of growing mushrooms in the dark is that darkness preserves the moisture that mushroom spores need to reproduce.

moisture

Mushrooms thrive in moist environments.

Button mushrooms need moist growing media such as compost or manure. Shiitake mushroom logs should be kept at a moisture level from 35 to 45 percent, which requires soaking for 48 hours in the event the logs become dry. Ideally, a shiitake growing log should have dry bark and moist inner surfaces.

temperature

Button mushrooms need temperatures between 55 and 60 degrees (12.7-15.6)Fahrenheit to grow properly, and strong drafts or dry air can kill them or prevent them from growing. The ideal temperature for growing shiitake mushrooms is between 72 and 78 F [22.2 - 25.6], but they can grow in temperatures from 40 to 90 F [4.4 - 32.2].

Keep logs in a shaded outdoor area or under trees to preserve their moisture and maintain an ideal temperature. Heaters or fans may be necessary to create the controlled environment button mushrooms require to grow indoors.

nutrients

Mushrooms synthesize the nutrients they need from organic material.

The particular nutrients they need to grow are sugar, starch, lignin, fats, protein and nitrogen. Compost made from manure and straw contains ideal amounts of these nutrients for growing button mushrooms, whereas shiitake are able to extract the nutrients they need from the wood of the logs or sawdust where they’re growing. A mixture of corn, peat moss and sand is an alternative to manure and straw.

A closure space to keep this specific microclimate is necessary for mushroom cultivation. As the tank shell would be gragually erosed in the following time as the specific landscape, a new closed shell consisting of wall and openings should be add into the tank space. This ‘shell’ also functions to support the tank original structure.

Enough moisture is the most important element for mushroom cultivation. Thus, a system is designed in this closed environment to keep the moisture level. General principle is the outside river could flow into the underground water storage where pipe in the middle of the tower could deliever the water into the roof water tank (that also collect rain water). Then the water flow down through the pipes in the hollow tower structures and reture the underground water storage.

Vapour is generated from the hollow structure when water flows down.And interior pools getting water from underground storage are layouted around the cultivation tower.

The principle of the water/vapour system shown in the previous page is learning from humidifier.

The closed ‘shell’ could help reduce the moisture loss in the cultivation environment and keep it in a suitable scope.These vapour could also create a beautiful mist atmosphere for human experience besides supporting moisture to mushroom.

The sun light has negative influence to the mushroom growing, which could not take nutrient and reduce the moisture level that mushroom need.

The strategy about the sunlight is to transfer it into soft indirect light by openning materials and arrange the opening location to reduce the direct sunlight. The indirect nature light will not influence mushroom growing so much, but take benefits to human nature experience and picking activities, which is also good for keeping enough temperature.

Part II conclusion

microclimate criteria and strategy The major function of tanks in this picking area is to grow high-quality mushroom for picking experience, which need specific microclimate.

Mushroom growing needs enough moisture, certain temperature, enough nutrient and context without direct sunlight. Therefore, a water /vapour system is needed to support moisture and creat mist atmosphere; extra heating strategy need to be considered to increase the temperature in the winter; openings for light should be careful in location and materials; and a new closed ‘shell’ is also needed to maintain the moisture and temperature as well as reduce the direct sunlight.

This part put all of these cultivation conditions and general strategies together to give an overall concept of mushroom cultivation microclimate criterias, while the detail strategies and technologies to achieve this microclimate will be detailly explained in the next part

43

Part III

Technologies for cultivation The third part is to demostrate the detail technologies about mushroom cultivation structure and microclimate in tank, as an explanation and expansion of the part I general tank reuse strategies and part II general microclimate study.

This part is divided into two semi-parts: first is about two types of mushroom walls, including mushroon cultivation on tank skin as living wall and mushroom brick wall to create that closed environment in part I; second is the cultivation tower structure and water/vapour system based on the tower in the middle environment to grow high-quality mushroom, which is the major cultivation structure and also helps to maintain the most important microclimate element.

The light strategy and roof detail is also belonging to this part, but being put in the appendix as an unfinished part.

Part III-1

Mushroom walls There are majorly two types of walls related to mushroom being introduced in this part: first is mushroom cultivtion wall by resuing the tank skin, which connect the inside and outside of tank with organic appearance to decorate the tank skin; second is a circle of new wall being added in the tank space to create a closed environemnt for the specific cultivation microclimate.

The first type of wall is also what my 1:1 project explore. The second wall is constructed by mushroom bricks which is made with the help of mushroom cultivation in this project and its features will be also introduced in this part. Apart from these two walls, the study is expanded to include the foundation being related to these two walls and demostrates the reuse strategy in the joint of original part and new part.

The material precedent study of the mushroom brick is from the Growing Pavilion, where I learnt the mycelium material making process and the circular relationship with environment meaning. mycelium panel making method: A unique power of mycelium is that it can easily be molded into any desired shape. The best way to do this is to fill molds with it. These molds can take various forms, from lampshades to chairs and facade panels. The molds are covered so that there is only minimal oxygen supply and they are placed in a dark, closed room. The molds stay there for four to five days. The mushroom spores start a slow process of breaking down the residual flows. The tracks create a natural network of connections through all plant remains. This way they glue everything together. The molds are then removed after a week in the humid environment and are baked at 80 degrees Celsius for two days. The mushroom growth process is stopped before the mushrooms actually sprout. This completes the production process and the mycelium designs are ready for use. circular relationship: The mycelium used for The Growing Pavilion establishes a circular relationship with the agricultural and horticultural sector in the Netherlands.

Supplier Krown.bio uses ‘residual flows’ from farmers. Residual flows are products that are left over at the end of a growing and processing process, such as stumps and branches. Currently it is customary to burn these residues or to process them into animal feed. However, design agency Krown. bio recently utilized these streams in a much more effective way by turning them into mycelium. In this way, they design and produce high-quality and natural products that are safe and sustainable.

The advantages of using fungal mycelium lie in the fact that it is 100% biodegradable as well as in its exceptional material properties.

More specifically, the bricks can be used as a both an insulator and as support for interior walls within a building. The mycelium tissue can trap more heat than fiberglass insulation, it is fireproof, nontoxic, partly mold and water resistant and stronger pound for pound than concrete. Moreover when dried, it can become very light, depending on the used substrate and its density: the mushroom brick weighs an astonishing 43 kg/m³, while concrete weighs about 2,400 kg/m³.

The rapid growing, tight mycelium tissue can expand under a wide range of environmental conditions and therefore allows a fast, easy, low-cost and energy material production.

Another characteristic is that, when placing two alive, individual mycelium bricks together, the mycelium will rapidly spread amongst them and become the bonding material.

Several advantages, its brutal appearance and its relationship with my project topic make me chose this material to construct the new wall for middle cultivation environment.

Part III-1 conclusion

mushroom walls To explore the detail technologies from outside to inside based on the general tank reuse and microclimate strategies, this part demostrates the technology of cultivation wall that reuses the tank skin and the mushroom brick wall that creates middle cultivation region. Both of these two walls use the mushroom and compost as brutal material appearance in two different status, but their technologies and functions are totally different. The cultivation wall totally relies on the original tank structure but the new wall needs the new foundation and floors to suport itself and and joint with the original tank.

The mushroom bricks as material of new wall have several adcantages, whose production can be supported by the cultivation in this region, so that the building construction and building funstions could help each other.

Part III-2

Cultivation tower and water system In the middle space of tanks created by the new wall, cultivation tower is designed as the major structure for high-quality mushroom growing and vapour creation.

The tower can be regarded as a whole functioning as the ‘column’ to support the roof, and its structures can load itself to allow people to walk on it and experience the picking. The structure holding the cultivation boxes with natural feeling create the atmosphere of ‘industry forest’, responding to the industry characters in the large oil refinery site. Pipes with relevant equipments are installed in these hollow structures to form the most important part of water/vapour system.

This is the transparent mushroom box for picking and observing designed in the 1:1 project, which was used in the cultivation wall on tank skin. In the final design, the cultivation wall on tank skin change to use exposed compost without transparent box, and the box change to be used in the cultivation tower, where the cultivation wall is purely formed by this boxes with compost as non-load-bearing elements.

The water/vapor system is designed to rely on the tower primary structure, as the most important system to maintain the specific microclimate and keep the moisture level of this middle cultivation area. The water run in a circle in this system: The water is pumped up from the underground water storage through the middle pipe to arrive at the top water tank, which could collect rain water, and then flow domn through the pipes in the hollow primary structure and finally return the underground water storage. In this process, small humidifire installed in the hollow steel structure could generate vapour (blue arrow in diagram 1).

The underground water storage connects the outside river to consist a large water system in the picking area and this water storage itself works like a reservoir to store the water and also drain the water out.

Part III-2 conclusion

Cultivation tower and water system The cultivation tower is the major design part to grow high-quality mushroom for experiencing the tank picking, being located at the middle cultivation area created by the mushroom brick wall.

Its importance make me decide to show its structure design in this part, with three levels of elements: the primary load-bearing structure is a hollow steel rigid strcuture with water pipes in it; the secondary structure use arch plate for asthetic purpose, which disperses the horizontal load; the third level of structure is the cultivation wall consisting of transparent cultivation box. The transparency make the box itself invisiable and emphasis the brutal feeling of mushroom compost to add the organic nature elements on the ‘industry forest’. The whole tower function as a column to support the whole roof structure.

The major part of water system linking the top and bottom water storages sits in the primary hollow structure and these two storages connect the environment water to form a larger water system.

Technical study conclusion The technology studies of new new forest design project explored the tank reuse strategy to grow the mushroom for picking experience and specific microclimate for mushroom growing.

This journal shows the study about tank reuse and the consideration towards the tank reuse strategy in the first part, as well as cultivaton conditions and microclimate strategy based on the reused strategy diagram in the second part.

The third part explain the technology details including the cultivation wall on tank skin, the new wall to create a middle cultivation context, the foundation join between old and new, mycelium materials, designing of the major cultivation structure in the middle cultivation space and water/vapour system to maintain the microclimate based on the tower structure. Light and the roof joint between new and old is also studied in the appendix.

During the study, the conditions of mushroom microclimate is learnt and strategies about seperating the space with special microclimate out but also building its relationship with larger context at the same time are also interesting. For example, the designning of water system support the moisture to the middle space which should be maintained by a closed context being seperated out of the outside environment, but this system could also connect with the large water system, which inspire me to understand more about both small microclimate and large environment. Additionally, the structure design based on the original tank make me consider more about the value of old structure and study how to design building under the limitation of existing structure.

It include two parts: appendix I is the light and skyligt detail being relavant to the mushroom cultivation microclimate in picking tank; and appendix II is structure and construction principle of living pavilion, as another type of building in picking area besides the picking tanks.

Appendix I

light and opening Lighting strategy is an important part for this specific microclimate, which is also studied and considered in the design process. The method to reduce the direct sunlight by carefully chosing opening location and materials is the major point to exlpore in the light consideration.

This part explore both the light strategy and the technology details of openings, but only the sky light together with the roof reuse strategy is drawn out.

Because of the time limitation, it could not be completed and precise enough in the content to put into the main body of the journal, but the content that I already have are still put in the appendix I to show design consideration.

Appendix I light and opening

Diffuse glass is focused on generating the best possible light transmission and diffusing the light that enters the space, which is used in my sky light.

Cultivation tower have distance with openings, so that direct sunlight could not arrive the tower but could light the tank space corridor before entrance towards middle cultivation area.

Sky light uses the diffuse glass to transfer the direct sunlight.

Appendix II

living pavilion Apart from the picking tanks as main buildings being analyzed in the main body before, the technology of living pavilion is simply shown in this appendix II part, in order to reduce the aspects that the main part focus.

This part only simply includes the structure study and construction principle done in the design process to show the possibility of curve timber grid, that is different from the principle of picking tanks in main body.

Right is the old version of living pavilion, and left is the final one with similar principle in site context. Original tank skin would gradually erose to leave the pavilion part stand, to make this area return nature.

Appendix II Living pavilion

108

The precedent of Downland Gridshell, chosen to study the timber structure, sits in an elevated position in an area of outstanding natural beauty on the South Downs.Timber was a natural choice for a structure to support the preservation of historic timber-framed buildings.While drawing on modern design and technology, the Downland Gridshell also celebrates traditional carpentry and building techniques.Its gently curving form and natural materials sit beautifully in the surrounding South Downs landscape of the Weald and Downland Living Museum in Sussex where the buildings and artefacts of traditional rural life are brought to life.

This curve timber frame principle and joins inspire the grid structure as the foundation for mushroom living into a pavilion in my project, which is not exactly drew out and studied in detail as a non-key building type put in appendix.

Appendix II Living pavilion

Based on the timber grid structure being studied before, the method of mushroom growing into a pavilion is considered. The process to achieve it is shown below: i. construct the grid ii. fix the composts on grid to grow the living mushrooms (yellow) iii. fix the new composts to grow new living mushrooms (yellow)between the old, that have been dry and processed after nutrient had been used up by mushroom growing(red) iv. repeat the step 3, more dry processed composts and new compost with living mushroom fill the grid. v.the whole grid surface is covered by the dry processed compost forming the pavilion with natural feeling.

The brief is to imagine the industry strip, bordered by the New Forest national park and Southampton ria, be recovered by the forest to change to its original border in 2050. The Fawley oil refinery in this strip is chosen as site to design and plan as a fungi forest park. Oil tank as the major facilities are studied and reused for various functions. All layers in this reused tank building would erose in order and this area will totally return nature territory in the far future

This 1:1 aims to study the inside and outside relationship of oil tank space, some of them will be resued as mushroom cultivation and picking space.

The idea of this wall is that outside mushroom blocks/logs and inside observing units could move oppositely to achieve interaction in two sides.

Additionally, this wall, include original tank skin and newbuilt timber frame, will be erosed in the future to leave the ‘core’ stand only.

interaction

precedent of timber frame: reused strategy of the tank is to reuse the tank skin and add the wall / supporting frame behind the skin. Both thick ‘core’ and light timber frame will be built behind the skin. The interaction wall choose timber frame as added structure to support the skin as it is easier to erose p i c k i n g a n d o b s e rv i n g
