PROJECT ABSTRACT A KIT OF PARTS TO BUILD THE CIRCULAR FUTURE

For the past 30 years Architects have largely operated in an almost post scarcity economic conditions. Land prices boomed, materials from every corner of the global we’re easily available and there was always some new innovation of our globalized economy on the horizon. Unfortunately it is becoming increasingly clear that this period of architectural history was an exception. In March 2020 the Covid-19 Pandemic swept across the planet and exposed the vulnerability of global trade systems. Practically overnight factories were forced to shut or radically alter their production. While freight services operating on Just in Time Delivery models suddenly developed massive backlogs and ballooned in price. This Thesis will explore how Architects might be able to create a set of universal components using common construction materials that can be assembled and disassembled with relative ease allowing materials to be reused in future projects reducing new material requirements and turning old structures into a resource than can be tapped by the construction industry, thus reducing reliance on imported material and lowering carbon emissions. While Disrupting the traditional linear model of construction in favor of a circular relationship. As a test case the kit of parts will be applied to two projects. A new Architecture Building at Swinburne University that will act as circular economy research center and teaching space for AEC Disciplines built utilizing the structure of the Existing SR Building. Then use the recovered components to explore their re usability providing club facilities and spectator stands at Auburn High School proving the projects circular economy credentials.

1/BACKGROUND AN INTRODUCTION TO WASTE AND THE CIRCULAR ECONOMY

METALS RECYCLED

PLASTICS RECYCLED

(Hyder Consulting, 2011)

INTRODUCTION TO WASTE The construction industry is one of the largest contributors to non-food waste in Australia creating 13,000,000 tons of waste each year. Of this waste around 60% is Recycled (Kabirifar, Mojtahedi and Wang, 2021) while on the surface this might seem like a decent figure there are a few key problems with recycling that make it less than ideal response to the problem of waste. As recycling usually requires high levels of manual labor, energy use and is limited to areas with specialized processing facilities. (Cáceres Ruiz and Zaman, 2022)

THE PROBLEM WITH RECYCLING

COSTLY

Usually requires a lot of manual labor greatly reducing profit.

ENERGY INTENSIVE Metals especially require smelting which is energy intensive.

SPECIALIZED FACULTIES Requires specifically designed facilities which may be far away from site and have limited throughput.

(Cáceres Ruiz and Zaman, 2022) (Reck and Graedel, 2012)

OTHER CHALLENGES IN THE CONSTRUCTION INDUSTRY The Covid 19 Pandemic In concert with the war in the Ukraine exposed the weaknesses of modern supply chains. Goods that we’re previously cheap and plentiful have suddenly become expensive with lengthy lead times. Combined with the many issues the world was facing before this latest crisis supply systems are under a level of stain that as not been experienced since the 20th Century. While this has presented problems across range of institution the construction industry been one of the most heavily affected. (OCED, 2022) KEY ISSUES Collapse of Global Supply Chains (OCED, 2022) - Leads to long waits for materials - Unexpected delays along with prices rises can disrupt construction schedules - Particularity has affected the construction industry. Climate Change (Müller, Krick and Blohmke, 2021) Need to reduce emissions in the construction industry and move toward methods that construction methods that produce lower green house gases and have longer lives.

Labour Costs (Deloitte, 2016) - In developed nations labour makes up a huge portion of the cost of a building. - These high costs compound when poor planning requires late changes on site. - Materials are labour intensive to install Material Independence (Productivity Commission, 2021) - The more materials a country has to import the more vulnerable it is to price shocks and global crisis. - Insecure supply chains mean that imported materials my be harvested from unsustainable sources or may use unethical labour practices in the supply chain.

A CIRCULAR RESPONSE Circular Economies are an economic production model that focuses on creating self sustaining loops within the economy that take materials that would otherwise be discarded and place them into Reuse, Re-manufacture or Recycling systems the key difference of circular approach to the older recycling systems is place recycling is a last resort if the material cannot be easily reused in this manufactured from. This results in materials that go through the circular economy being used for longer before being heavily reprocessed making more efficient use of their embodied energy and raw material use. (ARUP, 2016) (ARUP, 2018) Effects (ARUP, 2018) - Materials are not placed in landfill reducing pollution and land area used for landfill. - Reinserting these materials into the supply chain we can reduce the need to manufacture new materials and supplement existing supply chain shortfalls. - Processing of the materials creates local jobs in all areas close to where materials are produced and most needed. Components of a Circular Economies Reuse: Materials are in good condition and are easy to use and require litte extra labour to prepare them. By designing with this in mind architects can design components so they are as easy to reuse as possible and document both the assembly and disassembly of structures making it as easy as possible to reuse components. (ARUP, 2016) Examples: Unused construction material from a site, old electronics after users upgrade, out of style furniture, recovered steel beams from a demolition. Remanufacturing: Recovered materials that cannot be reused in their recovered form may require processing to restore their condition. This is generally more labour intensive than reuse and as result can be expensive making it hard to justify for materials that have low value on the secondary market. (ARUP, 2016) Examples: Brick usually needs to be cleaned to remove excess mortar and to restore appearance, refurbished electronics can be returned to manufacturers who replace any damaged components and replace the battery. Recycling: recycling is the most intensive of the 3 as it involves transforming a object back into a raw state. This is even more labor intensive and can also be quite energy intensive. Metals for example requite application of high heat to melt them down allowing them to turned into new forms. For composites and complex materials the recycling process can require removal of permanent glues, chemical processing, granulating and other intensive processes. A such recycling tends to favor materials that are of high initial purity or have high value to offset extraction costs. (ARUP, 2016) Examples: Metals, Paper, PETG and Glass All 3 of these techniques are an important part of circular economy but the most preferable will almost always be reuse due to it’s simplicity and low environmental impact as such where preferable this project will focus on reusing materials in their original state.

CIRCULAR ECONOMIES ARE THE SOLUTION

REUSE OVER RECYCLING A reuse first approach maintains materials in their original form allowing easy reuse.

REDUCED EMBODIED ENERGY

Material are derived locally not imported from overseas and have reduced processing costs.

SUPPLY CHAIN SECURITY

Supply chains the use reclaimed materials are more resilient against global disruption.

CASE STUDY 1 IN DETAIL

fig 1. Villa Welpeloo Exterior (Strauss, n.d.)

VILLA WELPELOO Superuse Enschedenther Netherlands, 2009

Designed for a couple who wish to showcase a collection of paintings by young artists. While also attempting to use as much recycled materials as possible. The project is around the reuse of industrial materials and machines and waste rather than just focusing waste recycled materials from the construction industry. The facade of the building is constructed of cable reels from the Twente cable factory. The steel structure is composed of columns from a Textile paternoster (a device for the storage and retrieval of rolls of fabric) and the roof beams from an old factory. Instead of installing a lift a scissor lift that was used in construction is permanently installed with some minor alterations. (Strauss, n.d.) Inside the house much of the art works and joinery also make use of recycled materials including chairs made from old signs and Kitchen Cabinets made from recycled plywood.

fig 2. Living and Gallery Space (Strauss, n.d.) The art works on display also shows off circularity here the table is made out of a reused billboard.

fig 3 & 4. Lift and Kitchen Area (Michler, 2011) The lift is an industrial scissor lift used during construction that was installed permanently.

CIRCULARITY STRATEGY: RECLAIMED TIMBER FACADE

The entirety of the buildings facade is constructed out wood reclaimed from industrial cable spools. The facade has a approximate external area of around 395m² that means that in order to cover the entire area at least 43 spools would be required to fully cover the facade. This figure assumes that all sections of wood from a spool are reused. The round upper sections of the spool may have to be joined together to get timbers of uniform size. Alternatively the builder could discard sections that are too short but this would obviously create additional waste so it would be ideal to minimize offcuts. From the photos it appears that each timber on the facade is lapped (see detail) shorter sections could be placed behind the longer ones hiding joins and reducing waste it is unclear if the was done in this project.

Shown above is 3D detail of the facade that illustrates how each of the main recycled materials are used in the facade. The details show that even when working with reclaimed materials that might have variable levels of quality it is still possible to design a clean high quality that successfully integrates all of the recycled components. This is helped greatly by using recycled materials that are as close as possible to standard industry materials. For example the reused steel beams are standard European HBA 140 profile making it extremely easy to use due to it’s known structural performance and common use. The cable spools while requiring some processing to break down are composed on untreated wood making them easy to work with. The use of close to pre-finished materials does make products much easier to reuse the harder problem is making use of construction waste that cannot or is very labour intensive to reuse in the general industry.

CASE STUDY 2

fig 8. Exterior view of the “The Circular Building” showing exposed superstructure with visible bolted connections (ARUP, 2016)

THE CIRCULAR BUILDING ARUP London United Kingdom, 2016

“The Circular Building” was a 2016 experimental building designed to be a test platform for the construction industry might go about building a truly circular building. The projects main goal was to create a building that was low waste, self supporting, and able to be dissembled and reused once the installation concluded. There are two strategies that we’re employed by ARUP to achieve this firstly the steel structure relied on bolted and clamped connections rather than welded connections which would typically be used for steel structures. Secondly the building was designed as a series of layers as shown in fig 9. the steel forming the key structure of the building with facade

elements being attached as a series of panels that could be bolted to the structure and then removed intact during disassembly. The design of this system is very important as it is usually in the cladding of a structure that the most irreversible connections are used such as glues, nails, staples and spray foams. By creating a panelized system the designer allows for some use of these connections which have many desirable qualities while also designing in the connections at the panel level that will allow them to be reused. (ARUP, 2017) Another key aspect of the project was the installation of a suite of sensors that closely monitored the performance of the building and a QR code tracking system that allowed each component of the building to be easily tracked during the disassembly process. (Santos, 2017)

CASE STUDY 3

PEOPLE’S PAVILION ARUP Eindhoven Netherlands, 2017

Like the Circular Building the Peoples Pavilion was designed as a temporary structure with a heavy focus on creating demountable connections. The key focus of the project was designing with “borrowed” materials that had come from demolished building or loaned from the manufacturer before going to be to used in their originally intended building. By doing this the project aimed to create a structure with zero carbon footprint.

Material sources Roof - Borrowed from Greenhouse Company Facade - Saved from Demolished Building Lighting and Heating - Borrowed Bar - Borrowed Plastic Tiles - From recyled PETG bottles This building is fantastic exmaple of the pay of designing and planing for reuse by creating a system that allows for material borrowing to become a core part of the construction industry we can create structure with almost no carbon footprint after the initial building has reached the end of it’s lifespan.

THESIS QUESTION

CAN WE CREATE A KIT OF PARTS THAT ALLOWS US TO REUSE THE CORE OF A BUILDING REDUCING MATERIAL WASTE, ENERGY INTENSIVE RECYCLING AND OVERALL EMBODIED ENERGY?

3/DESIGN FOR DISASSEMBLY DESIGNING THE KIT OF PARTS

KEY PERFORMANCE REQUIREMENTS STANDARDIZED

Where Possible Use Standard Construction Materials

REVERSIBLE CORE

All Core Structure other than the Slab can be Disassembled via the use of reversible connections

STANDARDIZED LENGTH Common set of lengths to minimize the number of unique components

SCALABLE

Able to be used from buildings at a range of scales

LENGTH

Longest Structural Member Size of 10m to Allow Easy Road Transport

BUILDING LAYERS

By separating core structure from elements with shorter life spans we are able to selectively replace elements of the building lengthening the life span of the entire system

BASED ON THE ANALYSIS OF THE CASE STUDIES I DEVELOPED SET OF KEY REQUIREMENTS THAT WOULD GUIDE THE DESIGN OF THE COMPONENTS OF THE CONSTRUCTION KIT 27

THE KIT OF PARTS

Using the performance requirements as a guide i selected the key components of the kit. Here the focus was on selecting products that already existed in standardized forms to allow the system to be easily sourced across the country protect it from being discontinued. And to create something industry was conformable with using. As such the components primarily draw from ISO steel profiles, prefabricated facade panels at common spacings and standard roof panels.

THE KIT OF PARTS - PANELIZATION

From this Slection of parts I then combined them into a set to panels that shared a common base unit allowing them to be used together in a range of combination to achive architecture of diffrent scales the key driver was the steel wall panels from which the rest of the sizes we’re determined

DESIGN LOGIC

1. Panel Sizes are based on a base horizontal unit of 2400 Allowing for a range of spans up to 9.6m and 600 spaced facade elements, Floor to ceiling of 3800 allows for flexible programing.

2. Standard Steel profiles allow system to easily be created in any ISO standard steel country and ensures that parts will always be available to expand the system.

KEY STEEL CONNECTIONS

Steel Connections where kept standard where possible above is a collection of common connection that occur in the structure designed to connect using rigid and non rigid bolted connections so as to avoiding welds unless absolutely required. The connections are based on the standard connection design from the Steel Designers Handbook (Gorenc, Tinyou and Syam, 1996)

System in context showing all the panels being connected into a simple box here we can see the layer approach allowing the decision to be made about which side of the building gets louvers. In future this could be expanded to offer a range of different facade and shading systems to introduce visual variation into the system and expand the systems vocabulary. 34

PRIMARY SITE

fig 1. Site Extents Satellite View (Google, 2022)

SWINBURNE UNIVERSITY SR BUILDING

SWINBURNE UNIVERSITY, HAWTHORN, VICTORIA 3122 Sitting a the heart of campus the SR building is generally unremarkable building that is easy for the casual visitor or student to walk past. Despite the building enjoying close proximity to the highly trafficked John Street and student residences. The building currently provides a few specialist rooms from OT student and the campus’s dance studio. But it’s placement between the Swinburne Advanced Manufacturing and Design Centre and ProtoLAB makes the site ideal for a new architecture building

that will programmatically connects unite the design school and provide a physical presence for architecture on campus rather than having to share existing facilitates. The Building will also provide architecture student with permanent studio space. AS the Architecture school is new and constantly growing it is likely the facility will need a larger space in the next 15-20 years as such this building will be an ideal candidate to test the kit of parts and reuse concept

EXISTING CONDITIONS SUMMARY - Existing Campus Building - Provides Nursing Specialist Rooms - Occupational Therapy Rooms - Dance Studio - Centrally located on campus but easily ignored. - The missing heart of Campus!

SITE PROPOSAL - Architecture Students Currently Lack Dedicated Studio Space - Create a new hub for Architecture on Campus - A showcase of the circular economy - Design for medium term life space to prepare for replacement as the facility grows over the next 15 years

EMBODIED ENERGY

TOTAL: 17000GJ

TOTAL: 220T/CO2

Using the Epic embodied energy database i carried out a calculation of the approximate amount of embodied energy that went into the construction of the current structure based on the large amount of energy already expended it was decided to preserve as much as the original structure as possible to maximize energy savings.

fig 5. Auburn High School Grounds (Google, 2022)

MATERIAL REUSE SITE: AUBURN HIGH SCHOOL 126 Burgess St, Hawthorn East VIC 3122 Auburn High School is a coeducational high school located in Hawthorn East the school has approximately 500 students. The school is composed of a four level main building which contains classrooms and administrative faculties, an indoor gymnasium and lecture theatre and extensive outdoor sporting faculties including a cricket pitch and soccer fields. The main school buildings are currently undergoing a major refurbishment along with the addition of a new preforming arts center and some alteration to the grounds closest to the school. The sporting fields are open to the public when not in use by the school and are also used by the nearby Schools, a number of community teams also use the grounds for games and training. The outdoor fields currently lack any protected outdoor areas for spectators or teams

there are presently no club rooms on site for community teams to stage events and the only onside facility is small old brick building with toilets and some limited equipment storage. As one of the outcomes of this thesis the dissembled materials from the circular economy hub will be used to construct: New Club Rooms with a small event space, change rooms and additional storage space. Along with sheltered spectator seating on the eastern side on the grounds. The proposed new structures will be evaluated by the amount of reused material from the initial structure and the embodied energy savings over a brand new structure.

EXISTING CONDITIONS - School of 500 Students - Large Grounds and Strong Sport Focus - Grounds also serve public teams - No spectator facilities and old very limited equipment storage. fig 6. Auburn High School Main Building (Google Maps, 2022)

PROPOSAL - Using the reclaimed components from the Swinburne design hub create a new club house and spectator area for the grounds - Acting as a test case for the reuse of the system similar buildings could be rolled out to other sporting fields fig 7.

EXISTING BUILDING

Existing Building On Site

As previously covered the decision was made to preserve as much as the original building as possible the other key preservation decision was to maintain the three large gum trees of the east of the site this placed restrictions on where the building could be extended.

Areas of Demolition

Shown above in the blue are the building areas that are to be demolished fully it has been limited to the front facade and roof of the single story extension on the sites east.

ITERATION 6

A range of massing experiments explore how we might extend and build on top of the existing structure. Here i established the the idea of hanging the new area off the old elements to create a division between new and old and get extra foot print to the rear of the building. I also experimented with extending the structure over the train line but zoning regulations made that infeasible.

PROPOSAL

Exterior View of Proposal

N Based on the application of the kit to the remaining features and my massing studies i developed the above final proposal the design focus on activating the front of the site introducing a new lecture theatre and social are at the front of the building while also introducing a new entry at the rear of the building as the levels advance the building becomes more private transitioning into the Architecture Studios

DISASSEMBLY & TRANSPORT

At the conclusion of the buildings 15 years or so life span it are the disassembled the dissembled components loaded onto flatbed truck in conformance with VicRoads transport regulations. The main components can be transported in a relatively low number of trips this combined with the close proximity to the reuse site minimizes carbon emissions during transport.

PROPOSAL

Using the recovered components from the Circular Innovation Hub we can build the club house and spectator stands for the Auburn High sporting fields the terrain on the west of the site is elevated providing the ideal place to create an elevated platform for spectators with a BBQ area pushing the kit into quite different application

N The Proposal manages to reuse around 50% of the steel work from the innovation hub see next page for a full tally and is almost entirely constructed out of the reclaimed components resulting in a structure that is both low cost financially and in terms of energy.

ENERGY SAVINGS According to Trelor and Fay (2005) on average a commercial building has an initial embodied energy of 15 GJ/m2 of floor space i’ve added a slight loading of 3GJ to this figure to account for the extra EE of school buildings. Using this figure its is possible to calculated how much embodied energy was saved by utilizing the existing building and how much was saved by reusing the recovered materials to build the Auburn High spectator stands.

Total Embodied Energy in Existing Structure Total 17,000GJ

Embodied Energy of Extension 18,311GJ Embodied Energy of average of building with same floor area 26,668GJ Savings | 26668 - 18311 = 8,357GJ

Embodied Energy Saved via Reuse 6,010GJ As shown by the EE calculation due to the extensive use of steel this kit of parts actually has a higher initial embodied energy than a more typical building. While we we’re able to 8357GJ vs constructing a brand new building all those savings come come from the reuse of the existing structure. Had we built a brand new structure using the kit of parts we would have likely used substantially more energy than a more traditional building. The savings of the system only start to come into play when the system is reused in the reuse example we recover 1/3rd of the total embodied energy. The spectator stands are a special case don’t make extensive reuse of the PC panel if we we’re to use the reclaimed materials on building closer to the original we would increase the savings even more.

CONCLUSIONS

Looking at the final analysis of the initial EE of the Swinburne Project and the Auburn High Projects. I think final system is broadly successful while the system does have higher EE costs during initial manufacture that are no so high that they cannot be recovered when reusing the components in a secondary project. And the benefits will only increase the more times they can be reused. The Key challenges facing the system will be ensuring the components are actually reused at end of life this could be added by tracking system and careful documentation. To increase savings more optimization of the system are no doubt possible and will increase the savings. Had i had more time i think the logical expansion of this system would be expanding the kit to allow for the creation of a wider array of architectural forms, explore other compatible facade systems which may help reduce EE and increase possible aesthetics of the system. Additionally there is the possibility of integrating a secondary lighter weight system that can be used in areas that have less structural loading in a secondary material that could be used to further control EE. However it’s worth considering that the more unique components exist in the system the more new components are likely to be required with each reuse as it is unlikely the old and new structure will have the same part requirements as such any expansion of the base panel system should be somewhat conservative.

6/APPENDIX USING RHINO.INSIDE TO AUTOMATICALLY EVALUATE REVIT MODEL EE

DIGITAL QUANTIFICATION OF EMBODIED ENVIRONMENTAL EFFECTS USING EPIC, GRASSHOPPER AND REVIT EP.iC Database The Environmental Performance in Construction initiative is a project by the University of Melbourne to create a free open access model for accessing that embodied environmental effects of construction projects. The database if notable for being one of the few free models covering Australia. Regional differences in terms of materials used and differing production and transport methods make the use of overseas data in accurate for the Australian context. Revit -> Grasshopper -> EPiC Connection EPiC is currently primarily interacted with as a plugin to Rhinos Visual Programming Interface Grasshooper as Rhino is not a full BIM modeling suite it can be time consuming to correctly model all the materials required to generate accurate material geometry in rhino for assessment by epic. This is especially true of complex building components such as layered walls, floors and roofs. Revit however is able to correctly quantify the layers of a wall along with correct calculation of joins and thin layers. So in order to combine the advantages of each platform i have created a more advanced script that uses the Rhino.Inside Revit connector to pull in the appropriate geometry and material take offs into grasshopper sort them by wall types and do material take offs before passing the results to EPiC for analysis. Over the next few pages i will briefly explain the main data processing techniques used to correctly sort the data from revit for processing.
