FPA Material Reuse Catalogue

Acknowledgements

We started this catalogue because we wanted to capture and communicate the learning that we had gathered discussing and testing reuse opportunities over the past few years. We wanted to create a material by material reference, in a standard format, where the relevant information could be picked up and developed by any designer.

The challenge of collating this information was eye-opening.

Providing a level of detail that is comprehesive (without being overwelming), yet approachable (without being oversimplified) was a constant balancing act. We don't expect to have covered everything, and we know industry capabilities are constantly evolving, but we hope we have provided information that can springboard further investigation.

As with all material reuse - it is inherently a collaborative process. We need clients, designers, contractors and suppliers to work together to share knowledge and find solutions.

This is how we wrote this guide, we could not have done it without the detailed input of our collaborators. We are very greatful to these committed individuals who gave up their time to capture their knowledge and experience, in the hope that this will drive action across the industry.

1.0 How to read and use template Turning theory into action

Instructions When implementing the reuse strategies and theories learnt in the Material Reuse Guide, the Material Reuse Catalogue will help you navigate the decision processes for reuse on a material by material basis.

The Catalogue is a collection of materials researched for reuse purposes and will help you navigate steps 2-4 of the reuse process set out in the Reuse Guide. Rather than read the whole guide, navigate to the elements that are relevant to your project.

Sharing knowledge is key to growing a circular economy.

This collection is the beginning of an expanding library to help fast-track the reuse process to help you on your reuse journey.

Please use this as a guide to begin your research journey.

Inside you find common materials, but there will also be specific conditions particular to each project or site and the supply chain is constantly developing new opportunities. For new or materials, use the template to create your own and add to this library.

The first chapter is an example explaining how to read and use the catalogue template. Refer to this each time you work with a new material.

Share updates as new materials are explored and new reuse opportunities develop.

1.2 Organising material systems Building layers

Buildings aren’t static objects. They are layers of components and systems with different rates of Thinking about materials as building components categorised in system layers helps us to target reuse approaches are change. suitable for the functional and life cycle requirements of each The concept of 'shearing layers' describes how buildings are composed of different systems that age and change at different rates (Stewart Brand, 1994). 'Shearing' explains how each layer should be able to flex independently, without compromising systems with different lifespans.

layer.

The layers are defined as: Site is ground the building is built on, which remains constant, but the context surrounding the building can change.

Skin is the facade and roof of the building. This can require updating to differing extents every 15-30 years depending on the system used.

Structure is the foundations and load bearing elements of the building. It is the most expensive element to change and usually has the longest lifespan, but it can be hard to adapt if requirements change. The structure usually contains the most embodied carbon.

The Space Plan describes the layout of the internal walls and partitions. These move with tenant preferences and as the functions change.

Stuff is easy and quick to change based on user requirements. For example furniture and loose fit-out items that change with trends and use patterns.

Recovering materials by layer helps the team to organise the materials according to their location, design and construction package, and to consider their different lifespans and requirements.

Services include HVAC systems, lighting, water and fire systems, as well as moving parts like elevators. These often become costly to maintain as warranties expire and more efficient systems are developed.

Key sub-types Describe the different sub types of the material if applicable. e.g.

– X component or type has Y properties – W component or type has Z properties

Condition This should provide a guidance to factors that might need to be considered when sorting materials by condition. For example, the element must not have rusting or broken edges, scruff marks are acceptable.

Re-certification process Some materials will need to be re-certified before they can be reused. Re-certification is often a significant challenge for the reuse of materials. This section should evaluate the viability of re-certifying the material. If re-certification is feasible, the process typically begins with the removal of the material, which needs to be addressed early in the discussion.

Embodied carbon Embodied carbon of the material/element: Source of data should include ICE database, EPDs, One Click LCA. Note: This section exclusively focuses on the embodied carbon content of materials and elements. It does not account for ‘Carbon Saved,’ which involves calculating the net benefit by subtracting the carbon required to prepare the element for reuse from the carbon that would be needed to produce a completely new element.

Ecological impact This is a developing knowledge, refer to UKGBC embodied ecological impacts webpage for more information and review EPD information on environmental impacts where appropriate.

Additionally, contractor and subcontractor information is crucial in this section. Each step of the process should be clearly documented.

Skin 2.1 Precast Concrete Chapter input by façade engineers FMDC and structural engineers Heyne Tillett Steel.

Key properties Precast concrete is a versatile material that is used in many parts of construction, including structural elements and as cladding. This is due to its many properties some of which are listed below: – High compressive strength – Typically reinforced with steel rebar to provide tensile strength but can also be without.

– Good fire performance – Robust – Low maintenance – Can be prone to staining – When used as cladding, panels can incorporate an additional facing material (e.g. brick slips, terracotta tiles, stone).

Key sub-types Precast concrete can be divided into two main classifications: load bearing and non-load bearing. In the past, it was also used in smaller sizes as cladding tiles, requiring a support sub-structure.

Load bearing cladding systems provide; – Inner structural panel (part of main structure) – An insulation layer – Outer non-structural panel (as cladding) Non-load bearing cladding systems provide; – A self-supporting cladding elements – Air and weather barrier This section will focus on non-load bearing systems, i.e. the single-leaf precast cladding.

Condition Pre-cast concrete panels can be reused in various applications such as new façade panels, stair treads, and new tiles. A detailed banding strategy will help to identify potential for reuse. Some factors to consider are listed below but this will vary project to project, depending on their original size and configuration.

Re-certification process Prior to deconstruction Ferrous scanning determines rebar levels in concrete and measures residual cover over the rebar. Tests will need to be

18

carried out on the concrete to check for defects and strength.

Drilling a hole into the concrete will quickly reveal if there is rebar or other impurities to the material that could affect its reuseability.

Post deconstruction Cut panels must be tested to meet performance requirements for reuse. Cutting precast concrete panels exposes rebar, making them unsuitable for reuse in weatherexposed applications, unless a suitable anti-rust treatment can be agreed with a specialist. There is also an opportunity for internal use, where exposed rebar is less of a problem.

Embodied carbon Cement is essential for creating concrete panels, but its production generates high levels of CO2. This process contributes to 8% of global carbon emissions.

Embodied carbon varies significantly depending on the amount of cement replacement and steel reinforcement required.

Approx. 0.22 - 0.28kg CO2e/kg (A1-A3) for standard precast concrete lower if cement replacement is used.

Ecological impact Over 46% of aggregates are used in manufacturing cement and concrete. The extraction process significantly impacts biodiversity and oceans. During this process, over 1,000 species are threatened.

Cut & Lift If the strategy is to reuse whole panels, then they need to be removed as individual pieces with an appropriate size crane, after being detached from the main structure.

If panels are to be broken down into smaller pieces on site, then sections are either or cut with track saws of holes are drilled through the concrete and diamond wire fed through to create a look and cut through.

Additional labour required and equipment required, at least 1 x additional person to drill and cut and then second person needed for the lifting of the slab.

Additional costs if working on uneven surfaces.

Panels will be large and heavy so will need adequate storage and arrangements to guarantee stability.

Crushed 1. Machine with breaker attachment will break through the concrete into rubble.

None - this is current practice across all sites.

2. Material moved to ground floor for further processing (On site crusher) or sent off as waste.

3rd party Concrete is harder to donate but there are some companies that are doing material development on this.

Lignacite (blockwork), Biolth (paving slips), EFC concrete (Earth friendly concrete).

Will require all the concrete panels to be extracted separately and placed into a separate bin to avoid contamination.

WORK SHEET: Possibilities and Priorities Reuse opportunities and process Examples

Reuse Re-use Panels Panels in good condition can be reused ‘as new panels’ in their original sizes, if a “recipient” building can be found, which can be challenging. Alternatively, panels should be tested for performance and structural properties before reusing.

If panels recovered from a donor building are deemed appropriate to use “as is” on the recipient building, panels can be reused.

This is subject to maintaining structural, weathering and thermal integrity i.e. Pre-cast concrete can’t be cut if it is to be reused as façade panels.

Repurpose Cut into decorative panels Panels could be cut into smaller sections for other applications.

Trimming or resizing will mean that rebar is exposed, and so a suitable treatment would need to be applied. This could mean the panels are only suitable for low-risk areas or as a rainscreen.

Precast concrete elements can be reused as stair treads after being cut and painted. However, not all panels are suitable for reuse, as their bending capacity will need to be assessed. When the existing panels with rebar are cut, if the rebar is exposed to the external environment it will corrode over time. To prevent this, special anti-rust paints can be applied.

Fig. 2.4

Paint panels to improve surface finish (durability and visual quality). Cut panels can be reused for non-cladding areas such as stair treads.

Trim into manageable sections.

Potential to use as king post system for plant screen or other non-structural walls. Ensure rebar is not exposed for external application.

Skin 2.2 Stone Chapter input by façade engineers FMDC.

Key properties There are multiple types of stone with different properties.

Stone is usally selected for its hardness and resistance to scratching and weathering.

Historically, stone was used as large blocks in mass walls, fulfilling both the asesthetic and the structural function.

Later, it also started to be used as cladding only, first in selfsupporting cavity walls and later also as a rainscreen.

The existing building stock offers many opportunities for stone to be reused, and in this chapter we are going to explore some innovative solutions.

Stone taken from façades will have good weather resistance so it will be suitable for both exterior and interior applications.

It is also highly resistant to wear and tear and should be able to maintain its appearance and structural integrity for a long time.

Condition Talk to a stone specialist to undertake a condition survey to establish the best way to remove panels.

If lime mortar was originally used in the construction of the stone wall, then it will be easier to deconstruct. If a different mortar was used, try other methods (such as cutting) to carefully remove the stone and take care in removing the stone in large peives for maximum retention.

Most stone can be reused as new after being carefully removed from the building, being cleared of gluing agents (typically mortar), and being surface cleaned. Some of the rougher finished materials will need to be sanded down or re-cut.

Re-certification process Prior to deconstruction – Stone Assessment: Includes visual inspections and structural tests to detect cracks, damage, or weaknesses.

– Once a sample is taken, material identification: Petrographic analysis confirms the stone type and its properties.

– Mechanical and Chemical Testing: Evaluates compressive strength, frost resistance, and contaminants like asbestos to meet UK regulations.

24

fletcher priest architects

Fig. 2.14

– Deconstruction Planning: Ensures careful removal to preserve stone integrity while adhering to the Construction (Design and Management) Regulations 2015.

Post deconstruction – Reclaimed natural stone undergoes material identification, mechanical testing, and chemical analysis to ensure compliance with UK building regulations, including strength, frost resistance, and absence of contaminants like asbestos.

– Dimensional verification assesses usability, while provenance documentation and certifications confirm compliance with standards like BREEAM. – Residual materials are removed to meet environmental regulations, ensuring the stone’s structural integrity and suitability for reuse in new construction projects.

Embodied carbon Approximately 0.1 - 0.3kg CO2e/kg (A1 - A3) can vary depending on the type of stone and method used for extraction.

Ecological impact Quarrying and (to a lesser extent) mining require a change in land use, which can damage habitats in the vicinity of the site, and the processes can produce air pollution. Quarrying also removes topsoil and can accelerate soil erosion.

Responsible quarrying can include remediation measures to restore biodiversity and create new habitats. Additionally, large amounts of fresh water can be used in the process.

De-mount Demo contractor to manually remove each stone panel.

Most stone will be salvageable and valuable to recover.

Additional labour and equipment required, at least 1 x additional person cut and then second person needed to remove and manoeuvre heavy panels.

Additional programme to demolition package. If intention is to further retain as full sized panels, increase cost and programme to be stacked an stored prior to collection/delivery to specialist stone company. To be arranged by demo contractor.

Common practice. If you specify aggregate, extra process required to crush stone into specific sizes.

Testing and storage will be required, resulting in added costs.

Will require all the stone panels to be extracted separately and placed into a separate bin to avoid contamination.

Should be included in demolition costs but additional care will be needed. Maybe a cost uplift for storage.

Skin 2.3 Brick (mainly clay) Chapter input by structural engineers HTS and brick specialists K-briq.

Key properties – Highly durable, weather resistant and stable – Can be easily handled manually, small alterations are possible.

– Excellent fire resistance and thermal mass Key sub-types Bricks are categorised as load bearing and non-load bearing. For non-load bearing bricks refer to section 3.0 Structure for more detail.

To understand how to deconstruct bricks you must first distinguish between mortar types.

Cement mortar vs lime mortar – Most handset bricks will use cement mortar.

– Some bricks will be laid in lime mortar and are easier to remove individually. Good quality recovered bricks usually have a high resell value.

– Bricks laid cement mortar are difficult to extract as mortar is stronger than the bricks.

Load bearing bricks are usually made for structural purposes and can be very durable if properly maintained.Refer to the London Brick Guide for more information on brick types.

Condition Early access to potential locations for brick recovery will allow brick specialists to assess the reuse potential. Scratching the bricks can give an indication of material strength. Check the bricks for potential metal contamination. For more information please refer to For this section refer to FutuREuse document “Evaluating the technical performance of reclaimed building materials” (D Baker-Brown, 2021).

Re-certification process Prior to deconstruction Perform a visual inspection to confirm the condition and whether it is load-bearing or non load-bearing and look for any evidence of moisture ingress, cracking or spalling. Contact a brick specialist or brick manufacturer to inspect the bricks as they are. They will be able to quickly tell you the type of brick material, mortar and estimate the period of manufacture. This will help you assess which banding to place the material - whether time should be spent in removing the bricks individually.

Once initial assessment is made, a trial of taking a portion of 30

bricks out is encouraged so the bricks can be crushed and their material qualities can be assessed.

Some of these test include: – Dimensions (as per BS EN 772-16:2011 – Gross Dry Density (as per BS EN 772-13:2000) – Unconfined Compressive Strength- Dry and Saturated (as per BS EN 772-1:2011) – Initial Rate of Water Absorption - Capillary Action (as per BS EN 772-11:2011) – Total Water Absorption- 24hr Cold Water Immersion (as per BS EN 772-21:2011 – Freeze -Thaw resistance (as per 772-18:2011) – Microscopy Analysis – Particle Size Distribution (as per BS EN ISO 17892-4:2016) Determining if the bricks can demonstrate meeting the same standards and requirements of a new brick, it can be factored into the reuse direction.

Post deconstruction Reclaimed bricks are usually not certified, but some salvage dealers will have done the above tests before reselling on the market.

Reclaimed bricks are not covered by British Standard, so specifiers should check that their insurance policies cover their use.

Embodied carbon 0.24 to 0.54 kg CO2e/kg. Figure for embodied carbon will differ depending on the mix/ materials used.

26 kg of CO2/m2 for clay bricks (2022 -British Ceramics Confederation) 26.5 kg of CO2/m2for concrete blocks (2020 - Marshalls PLC -Average) Ecological impact Firing bricks is energy-intensive, as is the production of cement often used in the mortar to bind them. The burning of fuel for firing bricks releases pollutants and ash into environment, affecting both soil and air quality. The removal and unearthing of large amounts of virgin materials for bricks has major impacts on habitats.

Donated If bricks can be reclaimed individually, bricks can be sold or donated back into the material market.

If bricks are crushed, K-briq can run tests to test compatibility to make new bricks,

DETERMINING THE RECOVERY METHOD Recovery method depends on the resulting value and use of the reclaimed bricks. The type of mortar significantly impacts the time and effort required for removal, as well as the final quality of the reclaimed bricks. Some bricks may have higher value as individual bricks but if a buyer is lined up to buy whole panels, it will affect how the bricks are extracted. Reuse route needs to be considered if not decided upfront. Some companies offer onsite brick cleaning services using excavators, providing quotes based on the number of bricks processed.

Skin 2.4 Glass Chapter input by façade engineers FMDC.

Key properties Glass is used in several parts of the building - including internal façade/skin. This section discusses glass applications in façade.

– Typically maintains its clarity and strength, with minimal degradation in quality.

– Thermal and solar performance of IGUs (Insulated Glass Unit) degrade with time due to gas leakage from the cavity and moisture eventually seeping into it.

– Generally high demand in the market.

– Unless processed in a way that alters its chemical composition (e.g. fritting) it can be recycled in closed loop.

Key sub-types Architectural glazing can be broadly categorised as follows: – Single (monolithic) glass panes can be annealed or heat treated (heat strengthened or toughened) to improve strength. They can also be coated to confer enhanced thermal and solar control properties when used in IGUs (see below).

– Two or more monolithic panes can be combined into laminated glazing with the use of interlayers.

– IGUs (insulated Glass Units) are made by combining two (double glazing / DGU) or three (triple glazing / TGU) glass panes separated by a tightly sealed cavity filled with inert gas (typically Argon) or air.

Non-intrusive surveys can be undertaken to establish the configuration (glasstypes and thicknesses) of sngle glazing and of IGUs. Look for glass kitemarks (stamps) in the corner of the glass; if present, a kitemark identifies ‘safety glass’, providing information on the type, the impact resistance properties, and the fire resistance, if relevant.

Glass specialists will be able to determine the configuration of IGUs with the use of simple tools. Saint Gobain will carry out surveys for free and buy collected cullet.

Thermally Toughened safety glass

Fig. 2.48

fletcher priest architects

Fire safety glass

Condition Direct re-use of IGUs is problematic because at its end-oflife (25-30 years) the unit will have likely lost its thermal and solar properties to some degree. Also, to be re-used, and IGU needs remain unchanged and retain its original dimensions.

Direct reuse could be possible if the specific application required lower performance parameters.

If reusing glass panes, the inner and outer glass layers of an IGUs can be separated and individual panes can potentially be re-used, with some limitations. However, this requires special machinery to avoid breaking the glass so it needs to be done off site, and it's novel process, still in its infancy and under research and development, and not yet common in the industry.

Close loop glass recycling is relatively simpler. It can be done on-site by carefully breaking the panes and collecting cullet in bags. Avoiding contamination is key. Bags of cullet will be transported to a recycling processor.

Contaminated glass waste can be down-cycled into container glass, glass wool insulation or other applications.

Re-certification process Direct glass reuse is very uncommon in the industry, therefore there is no known examples of re-certification processes to date.

In general, re-certification will depend on the new application, and the performance requirements specified for it. For example, if a single pane is to be reused as a balustrade, impact testing including post-breakage behavious will be required.

Embodied carbon Single glazing: 1.2 - 1.8 kg CO2e/kg Double glazed units: 1.7 - 2.2 kg CO2e/kg Triple glazed units: 2.1 - 2.3 kg CO2e/kg Values should be considered indicative; variation within range will depend on actual glass configuration (glass type and thicknesses).

Ecological impact Glass production significantly impacts the environment by releasing CO2 and greenhouse gases due to the high temperatures required for melting raw materials and the ensuing chemical reaction. The extraction of raw materials required to make glass (sand, soda ash, lime) impact habitats and potentially adds pollution to local environments during processing.

Prepare for reuse Glazing units suitable for reuse to be identified and carefully removed and stored safely to avoid breakage until they are transported to a storage facility.

Reuse of individual IGU panes After being removed from the building, IGUs need to be transported to a specialist glass processor. Once separated, individual panes can potentially be reused, although there are limitations.

Requires a glass processor owning a special machine that can separate the two glass panes without breaking them. It’s a novel process so its not common on the market.

Minor due to the process being still in development stage.

Closed-loop recycling or downcycling Closed loop recycling to make new architectural glass is becoming popular in the industry, with Saint Gobain Glass leading the way.

Any glass deemed not suitable for closed loop recycling can be downcycled to make container glass or other products.

For closed loop recycling glazing units need to be segregated from other materials to avoid contamination.

Then it can be either transported to a processor as entire units or broken in site under controlled conditions and transported with suitable bags. This is not required for downcycling.

Should be included in demolition costs but additional care will be needed.

Additional care when separating the material.

CAREFUL OF CONTAMINATION! If glass is selected for closed loop recycling it must be stored away from any metals and magnetic materials. The contamination can cause visual and structural defects.

Reuse As is If an IGU / single pane of a specific size is deemed suitable for direct reuse, it can be demounted ‘as is’ and reframmed to form new enclosures or balustrades. For IGUs that have lost some of their thermal performance, the application might be one with lower performance requirements. Specific testing might be required depending on the type of application.

Skin 2.5 Aluminium Frame Chapter input by façade engineers FMDC.

Key properties Aluminium plays a crucial role in façades as it’s used in the form of frames for window, doors and curtain walling, thus contributing to both aesthetics and functionality. Although other materials can also be used for such elements (e.g. wood, uPVC, steel), aluminium is the most typical one and will be encountered on most buildings.

Aluminum window and curtain wall facades need to meet a large number of key performance parameters including structural stability, air and water tightness, thermal and acoustic performance and security.

It should be noted that aluminium extrusions an also be used in other façade elements, for example as sub-structure for rainscreen cladding.

Key sub-types Aluminium frames are extrusions, typically made with specific alloys (6000 series) and then distinguished between the possible finishes: anodised, PPC (Polyester Powder Coating), PVDF, or mill finish (only for non-exposed elements).

When assembled in frames, they incorporate plastic thermal breaks (generally polyamide), gaskets, and possibly other filler elements that improve thermal performance and air / water tightness. When assessing recyclability, it’s important to keep in mind that some of these components might not be recyclable, or will need to be separated to be recycled independently.

Look for any labels or certifications provided by the manufacturer, typically included in product documentation or packaging, which may indicate the materials type, thermal performance ratings, or compliance with safety standards. If such markings are absent or unclear, further inspection may be required to verify the frame’s properties.

Condition Window / curtain wall frames can potentially be re-used as they are, although the obvious limitation is that they would need to retain their original sizes. Alternatively, frames can be disassembled and altered to form a new configuration, with the integration of new elements (screws, cleats, sealant, etc.).

In both cases checks need to be performed on the structural properties, on potential corrosion, and on the condition of the finish. Depending on the age and condition, the finish might need to be refurbished.

Re-use is uncommon in the industry at the moment, while recycling is the standard. Closed loop recycling to make new aluminium extrusions should be preferred to downcycling (e.g. cans and other containers). To ensure proper recycling, it's essential to remove non-recyclable components such as sealants, adhesives, plastics, and metal reinforcements.

It is essential to segregate the framing elements from any other metal (including aluminium of other alloys) to avoid contamination during the sorting and shredding processes.

Re-certification process For direct re-use, testing can be performed to guarantee the structural performance, and the air / water tightness of the window / curtain wall system. Since the latter depend on gaskets and other elements as much as on the profiles, it might be necessary to replace some of these. Any on-site and off-site testing is unlikely to lead to new warranties being issued, but it’s an essential process to gauge whether re-use is a possible solution.

Refurbishment of the finishes (most likely re-spraying) will allow to achieve a new warranty for them, albeit limited.

Embodied carbon Aluminium is extremely carbon intensive. Direct re-use would avoid all the carbon required to make new framing systems.

Closed loop recycling allows to avoid most of the emissions due to the electrolysis and the smelting processes required to make aluminium billets, thus producing elements with a much lower carbon footprint. The values below refer to a mill finish aluminium extrusion: - New (average European production) ~ 7.4 kgCO2e/kg - New (produced with renewables) ~ 4.7 kgCO2e/kg - 75% post-consumer recycled content ~ 2.5 kgCO2e/kg Ecological impact Re-using or recycling aluminium allows to avoid extraction of new bauxite and eliminates waste from its processing, which hugely benefits ecosystems.

Structure 3.1 Reinforced concrete slabs Chapter input by structural engineers Heyne Tillett Steel.

Key properties Also known as post-tension slabs are commonly used in flooring and roofing systems due to its efficient design.

Some of its traits are: – High compressive strength – Typically reinforced with steel rebar, enhancing tensile strength – Good thermal and sound insulation properties – Fire-resistant due to concrete’s natural fireproof characteristics – Can span long distances with fewer supports, offering flexible design options – Low maintenance – Prone to cracking if not properly installed or handled

Fig. 3.1

Key sub-types and properties There are many types of reinforced concrete slabs but the only type of system that has potential for reuse is precast slab.

Embodied carbon Slabs generally contain the greatest volume concrete for the structure so therefore contain the most carbon. So a great target for testing innovative reuse strategies.

In order of reuse difficulty (easiest to hardest): 1. Block and beam - including hollow core slabs 2. Pre-cast slab system without a structural topping potential to remove section that aren’t tied together 3. Solid in-situ slabs (potential for retaining and jacking slabs to a different level) 4. Post- tension slabs and precast slabs with structural topping

For reinforced concrete structures, the resulting material intensity ranged from 719 to 768 kg/m2, and the embodied carbon, from 163 to 196 kg CO2e/m2.

Condition Hollow core slabs can be reused if they are in good condition.

They should be inspected for cracks, damage, or corrosion in the reinforcement.

Slabs with surface damage may need repair or resurfacing.

Adhesives or fasteners should be carefully removed to avoid further damage. The slabs must be reassessed to ensure they meet the load-bearing requirements of the new design, which may require re-engineering or strengthening.

Proper handling during deconstruction is essential to preserve the slabs' integrity, ensuring they remain intact for reuse in large sections. For material testing - carbonation testing, Concrete strength - refer to euro codes for specifics.

If intent is to reuse, ensure no cross contamination by providing a dedicated skip bin for rubble.

CAREFUL OF CONTAMINATION! Metals found in demolition waste is one of the main reasons why much concrete can’t be reused. To mitigate this, intrusive investigations through concrete panels and slabs can reveal if any rebar is used. Where possible, avoid exposing any rebar. If exposed the rebar is vulnerable to rusting and a anti-rusting solution will need to be applied.

Contact local recycling facilities to see if they have the machinery to separate any rogue metals from concrete rublble before it is crushed into smaller aggregates.

Structure 3.2 Steel Chapter input by structural engineers Heyne Tillett Steel.

Key properties Steel is the perfect material to be reclaimed and used repeatedly when kept in its current form.

– It is strong, robust, stable and if kept in the right conditions (a warm, dry environment), and has an incredibly long lifespan.

– Typically composed of iron, carbon, and other IT alloying elements like manganese, chromium, or nickel, can be easily shaped, welded, and fabricated. Highly recyclable, it retains its properties through multiple cycles of recycling, as is business as usual.

– Steel reused as is will require minimal to no re-heating. If recycled, the steel will be fully remelted to be remade into steel.

As steel is widely used for its versitility, consider all steel elements including steel mesh, louvers, balustrades, posts etc. Any elements related to safety will need to be tested and rewarrantied by the manufacturer.

Condition Most steel can be reused as new after being cleaned and coatings removed and reapplied. Some of the rougher finished materials will need to be sanded down or recut.

Speak to engineer on other considerations.

Re-certification process Follow the process in SCI P427 and/or P440 (depending on the age of the steel) Recondition: CST / EMR, Recertification: Masteel, SGS, Metaltest, Sandberg Prior to deconstruction 1. Assess visual quality of the steel, grade in terms of acceptable damage.

2. Samples extracted for metallurgical testing.

3. Results determine appropriate products for reuse.

Before extraction The process for reusing is straightforward. The following information will need to recorded for each element: – A description of the structure. This should include a description of how the building is stabilised.

– The age of the structure, which may be from records, or local information.

– A preliminary listing of the steel components deemed suitable for reuse, with numbers in each group, e.g. numbers of rafters, numbers of floor beams.

Embodied carbon Steel within the construction industry is already a heavily recycled product. In the UK, the recycled content of steel is typically 20% scrap and, on the continent, where electric arc furnaces are utilised, this increases to 95% or more.

However, the process of melting the steel scraps and reforming still requires vast amounts of energy, around 1.7kgCO2e/kg as an average figure for structural steel sections.

3.03 kgCO2e/kg for electrogalvanized steel- with world average steel thin layer coating with zinc / zinc nickle. (Varies depending on the type and content of steel) Ecological impact Iron ore is the world’s most extracted metal and 98% goes into steel production. More than 86% of iron ore is extracted from Australia, Brazil, China, India, Russia and South Africa.

Open-pit mining destructs the habitat as the mines are generally located in remote and ecologically diverse areas, A significant amount of fresh water is used, causing local scarcity but it is also associated ecological damage caused by dam construction.

Reuse Unbolting steel whole

To reclaim them to reuse them, steel will need to be kept at full length which makes the deconstruction process different and it usually requires more labour.

Deconstruct High potential in reusing unencassed steel created after 1970. Exposed ends of beam with a machine with a small breaker attachment so that the ends can be sheared off and dropped safely.

Sections are then lifted to ground floor.

May require a crane to lift large sections down multiple floors. Label and reevaluated steel.

Recycle For scrap value

THE LONGER THE BETTER It hasn’t been proven that steel is still viabale once casing it removed. Focus on steel made after the 1970s, try and keep the sections as long as possible and avoid any drop cuts (where the ends are cut at an angle).

62

fletcher priest architects

Cost fluctuates a lot, and depends on the contractual arrangement. Reused steel can fetch higher prices than new steel. Not always a rebate however, after factoring in deconstruction costs.

WORK SHEET: Possibilities and Priorities Reuse opportunities and process Examples

Up-cycle As is Assess visual quality of the steel grade in terms of acceptable damage. Explore ways to reuse the steel without extraction e.g. painting, exposing or encasing.

After unbolting steel, existing holes will need to be repaired.

Historic plates, connections etc. will need to removed and deep cleaned. If the steel is to be reused structurally there are more onerous requirements (as listed in earlier parts of this section).

Consider disassembly and transportation early to avoid hidden costs and time.

Elements that can be dismantled whole can be re-sold to specialist reused steel stockholders like Cleveland Steel & Tubes and EMR.

Re-manufacture Cut into smaller sizes Keep elements as long as possible, until a reuse application is finalised. Beams will need certified structural testing before returning to the marketplace.

Structure 3.3 Brick (mainly clay) Chapter input by structural engineers Heyne Tillett Steel and recycled brick supplier K-briq.

Key properties – Highly durable, weather resistant and stable – Can be easily handled manually, small alterations are possible.

– Excellent fire resistance and thermal mass Key sub-types Bricks are categorised as load bearing and non-load bearing.

For non-load bearing bricks refer to section 2.0 Skin for more detail. To understand how to deconstruct bricks you must first distinguish between mortar types.

Cement mortar vs lime mortar – Most handset bricks will use cement mortar.

– Some bricks will be laid in lime mortar and are easier to remove individually. Good quality recovered bricks usually have a high resell value.

– Bricks laid cement mortar are difficult to extract as mortar is stronger than the bricks.

Load bearing bricks are usually made for structural purposes and can be very durable if properly maintained. Refer to the London Brick Guide for more information on brick types.

Condition Early access to potential locations for brick recovery will allow brick specialists to assess the reuse potential.

Scratching the bricks can give an indication of material strength. Check the bricks for potential metal contamination.

For more information please refer to FutuREuse document “Evaluating the technical performance of reclaimed building materials” (D Baker-Brown, 2021).

Re-certification process Prior to deconstruction Perform a visual inspection to confirm the condition and whether it is load-bearing or non load-bearing and look for any evidence of moisture ingress, cracking or spalling.

Contact a brick specialist or brick manufacturer to inspect the bricks as they are. They will quickly tell you the type of brick material, mortar and estimate the period of manufacture.

This will help you assess which banding to place the material and whether time should be spent in removing the bricks individually.

66

fletcher priest architects

Fig. 3.26

Once initial assessment is made, a trial of taking a portion of bricks out is encouraged so the bricks can be crushed and their material qualities can be assessed.

Some of these test include: – Dimensions (as per BS EN 772-16:2011 – Gross Dry Density (as per BS EN 772-13:2000) – Unconfined Compressive Strength- Dry and Saturated (as per BS EN 772-1:2011) – Initial Rate of Water Absorption - Capillary Action (as per BS EN 772-11:2011) – Total Water Absorption- 24hr Cold Water Immersion (as per BS EN 772-21:2011 – Freeze - Thaw resistance (as per 772-18:2011) – Microscopy Analysis – Particle Size Distribution (as per BS EN ISO 17892-4:2016) The bricks can demonstrate that it can achieve the same standards and requirements of a new brick. It can determine the reuse direction.

Post deconstruction Reclaimed bricks are usually not certified, but some salvage dealers will have done the above tests before reselling on the market. Reclaimed bricks are not covered by British Standard, so specifiers should check that their insurance policies cover their use.

Embodied carbon 0.21 to 0.54 kg CO2e/kg. Figure for embodied carbon will differ depending on the mix/ materials used.

Ecological impact Firing bricks is energy-intensive, as is the production of cement often used in the mortar to bind them. The burning of fuel for firing bricks releases pollutants and ash into environment, affecting both soil and air quality. The removal and unearthing of large amounts of virgin materials for bricks has major impacts on habitats. Over 46% of aggregates are used in manufacturing cement which is used in mortar. The extraction process significantly impacts biodiversity and oceans. During this process, over 1,000 species are threatened.

DETERMINING THE RECOVERY METHOD Recovery method depends on the resulting value and use of the reclaimed bricks. The type of mortar significantly impacts the time and effort required for removal, as well as the final quality of the reclaimed bricks. Some bricks may have higher value as individual bricks but if a buyer is lined up to buy whole panels, it will affect how the bricks are extracted. Reuse route needs to be considered if not decided upfront. Some companies offer onsite brick cleaning services using excavators, providing quotes based on the number of bricks processed.

Structure 3.4 Timber Chapter input by Structural engineers Heyne Tillett Steel and sourced from Materials Report Toolkit for Carbon Neutral Developments - Part 1, Bio Regional Development Group, 2003.

Key properties Structural timber refers only to softwood and hardwood elements such as beams, joists and columns. This section focuses on joists and studs.

Like brick reuse, the reuse of timber joists has been happening in an informal way for a long time. There is not much guidance on this so the same strategy applies - thinking of creative ways to reuse timber that doesn’t require strength grading or re-certification.

Fig. 3.46

The lack of an integrated supply chain to support the reclaimation and reuse of timber use is one of the main reasons why timber is not reclaimed in the first place. This puts more onus on the demolition contractor to store, find potential buyers and negotiate costs and changes. A wider knowledge of how to reuse aims to encourage a broader support network for reclaiming used timber.

repurposed. It is especially relevant for structures constructed or altered between the 1950 and 2007. This guidance requests contractors to classify waste wood at its origin depending on the expected level of hazardous substances. This will require segregation of waste wood on site, otherwise it will all be considered as hazardous waste and subsequently requiring specialist hazardous waste disposal.

Condition Before deconstruction, visually grade the timber. Refer to Waste Wood Assessment Guidance for timber grading.

Embodied carbon 0.26 kgCO2e/kg for Softwood 0.31 kgCO2e/kg for Hardwood

Typically, construction and demolition waste is considered as Grade B. Usually, this waste wood contains some non-wood materials prior to processing such as nails, metal fixings, paint, plastic, glass, grit, coatings, binders and glues (The Wood Recycle’s Association, 2021). Other conditions that affect the reusability are any fungal decay, straightness and, moisture content. However, there are many new products that can transform construction timber into reuseable products to avoid timber entering waste streams.

Timber also sequesters carbon, so keeping timber in use and avoiding landfill or burning keeps this carbon out of the atmosphere.

Re-certification process Unlike new timber that is graded, and CE marked, reclaimed timber lack certification, making results difficult to guarantee that the material is fit for purpose. Finding design solutions with a lower performance requirement can allow used timber to be repurposed.

From this, approximately 83% is processed, 1% ends up in landfill and the rest 16% is unaccounted (Wood Recyclers Association, 2019; TRADA 2020). Some of the timber is donated or sent to recycling facilities. However, the overall amount of reclaimed and reused material is unknown as the practice of reuse is informal. The majority of the waste wood processed is used as fuel in biomass for energy recovery including the waste wood exported as fuel. However, this remains highly controversial as unlike other renewable energy technologies, most of the current technologies used for the combustion of biomass generates carbon emissions (Office for National Statistics, 2019).

The Waste Wood Assessment Guidance for the Construction and Demolition sectors (Law, 2021) is an output of the Waste Wood Classification project that started in 2017. It provides guidance on the the identification of hazardous waste wood.

The Waste Wood Assessment guidance could help to identify non-hazardous timber members with the potential to be

Cable Trays

Chapter input by environmental design consultants Atelier Ten.

Key properties Distribution and containment includes non-movable parts such as ductwork, pipes, cable trays. Although commonly, modularised, ready distribution of containment is labour intensive and often overlooked during demolition.

Fig. 4.1 PVC pipes

Existing ductwork

Fig. 4.2

Fig. 4.3

Ductwork is an essential component of heating, ventilation, and air conditioning (HVAC) systems. It distributes air throughout buildings and is typically made out of galvanized steel, aluminium, or plastics making IT. Durable and lightweight. Often modular, so it is easy to maintain and replace, but it has limited reusability. Parts of the components can be repurposed for other systems.

Reusing pipework (steel, iron, copper or plastic) can reduce greenhouse gas emissions compared to buying new steel.

Pipe work for sprinklers, hot/cold water etc. could be reused subject to retesting.

Electrical containment such as cable trays, baskets and ladders are usually modular and can be reused as long as the fixings can be replaced and its condition is deemed acceptable. Cable trays are designed to support and organise electrical cables in a building of typically made from materials like galvanized steel, aluminium, or fiberglass. Designed to allow for ventilation, cable trays help prevent overheating of cables by allowing air circulation around them. Cable trays are easy to install and modify, offering flexibility in cable management.

Busbars are electrical distribution systems make generally of either copper and aluminium. They are modular and reasonably free of contaminants and could be removed and reused, subject to condition and testing.

Speak to a MEP consultant for other distribution and containment equipment that could be reused.

Condition Things to look out for when considering reusing support equipment are: wear and tear, holes, warping, rusting and disassembly potential.

Re-certification process The majority of containment equipment (cable trays etc.) shouldn’t need recertification it its in a good condition.

Certain distribution equipment like pipework and ductwork 82

fletcher priest architects

will need testing and recertification for its fire rating and leakage. Reconditioning process as below: Steps 1. Clean each section of the trays and trunking to remove dust, dirt, and any adhesive residues. For items that may have been cut, they may need additional treatment for its exposed edges.

2. Inspect each piece for structural integrity, looking for bends, cracks, or corrosion 3. Repair any minor damage or set aside sections that cannot be reused 4. Bundle the sections together securely, using ties or straps to keep them organized during transport.

Embodied carbon Most MEP containment and distribution is made of metals or sometimes plastic and as such have high embodied carbon. In a large building, distribution can account for a significant part, sometimes 60% of the MEP upfront embodied carbon.

Ecological impact Mining of metal used in the making of ductwork is energy intensive process which destructs habitat and soil. Some uses flexible plastic which contributes to fossil fuel depletion, air and water pollution. The manufacturing process generates waste materials, including metal off cuts, plastic scraps, and chemical byproducts. Improper disposal of these materials can lead to environmental contamination.

DATA SHEET: Investigate

Sinks

Chapter input by environmental design consultants Atelier Ten.

Key properties Fittings refer to items related to sanitaryware such as toilets, sinks, urinals, vanities and shower trays etc.

Equipment for MEP includes AHUs (Air Handling Units), Boilers, Chillers, Generators, Condenser units, Cooling towers, pumps, LV panels, water tanks etc. Other equipment are related to access and maintence such as BMU units and lifts. A site visit with a MEP team can quickly identify any equipment that is still in good condition and has warranty.

If considered for reuse, tests will need to be conducted to validate reusability.

In general, buildings undergoing major renovations will have MEP equipment at their end of life or equipment that doesn’t meet current standards. However, always check with suppliers and MEP consultant to identify the newest equipment.

Most water tanks can be reused, but the size and capacity may not be appriopriate for the new project. If so, there are many reclaimation sites that accept water tanks. There is a growing market for leasing MEP equipment with some lift and luminaire companies providing services that install, maintains and then removes for reuse and recycles at the products end of life.

Speak to a MEP consultant for other equipment that could be reused.

Condition Things to look out for when considering reusing MEP equipment are: life span, wear and tear, water damage such as mould or leaking, holes, warping, rusting, energy efficiency, and disassembly potential.

Re-certification process Reconditioning processes will differ for each equipment.

Contact specialist for more information. The majority of MEP equipment will need recertification. But sanitary fittings can usually be reused.

4.3 Light Fittings Chapter input by lighting specialist Erco.

Key properties The reuse of light fittings is still in its early stages, but it presents a valuable opportunity to reduce environmental impact.

Manufacturing new luminaires (the light) and fittings (the casing) has a significant footprint, making reuse a sustainable and responsible choice that should not be overlooked.

the amount of light you get for each wattage used once the light has left the luminaire, e.g. 100lm divided by 10w = 10lm/w. It is very important to note that it is not the amount of light from the LED Light Source. Not all luminaires are built the same, and many are not capable of meeting these requirements. This is why it is important to read through manufacturer specification documents.

PART L dives into many other aspects of lighting, including the way in which it is controlled, so it is certainly worth a read.

This section briefly explores current technologies and strategies related to the reuse, remanufacturing and recycling of the large amount of fittings found in an office environment. The lighting industry has always been subject to a ‘‘make and dispose of’’ type of linear economy, particularly with short-lifespan fluorescent and halogen luminaires. However, LED lighting (with a much longer shelf life) has played a huge role in changing how we think about (and use) lighting and is much more energy-efficient.

Over the last decade, the transition to LED lighting, mostly in commercial buildings, has accounted for the highest share of electricity consumption.

Condition Things to look out for when considering reusing light fittings: cracks, rust, lifespan, and overheating. Harmful chemicals can be released if fluorescent lights break. Contact a specialist for safe deconstruction.

Apart from refurbishing existing light fittings to add new life and functionality, parts harvesting is another loop in the circular economy for lighting. Many existing lights contain small amounts of mercury, which is harmful to the environment and needs to be disposed of properly. Only incandescent and halogen bulbs can be disposed of with regular waste.

Embodied carbon When working on the refurbishment of a workspace, it is important to look into the carbon-related global warming potential of the light fittings being specified. This can raise a question: is it worth remanufacturing existing luminaires within the space or is it more appropriate to purchase new fittings altogether?

In October 2021, CIBSE released TM65 documentation providing guidance on how manufacturers can report on the embodied carbon in some aspects of a product’s life cycle, from manufacturing to installation, maintenance and end of life.

Specifying a luminaire with low-embodied carbon can assist the overall project in meeting certain accreditation. It is worth noting, however, that these scores are self-certified by manufacturers so please double-check your information.

Key sub-types Firstly, identify what type of lights you are recovering. With the exception of LED light sources, these can no longer be sold in the UK and EU. While the light source itself is not officially banned, the government has implemented Minimum Energy Performance Standards (MEPS), forbidding the importation and sale of light sources with an efficiency lower than 120 lumens per watt.

There are 5 types of light fittings: Fluorescent tubes, halogen bulbs, compact fluorescent, incandescent light bulbs and LED light bulbs. The only type that is deemed reusable, due to its long and efficient lifespan is the LED light.

When it comes to office lighting, referring to PART L. Building Regulations (2021 Edition) when specifying light fittings will provide you with plenty of information on what type of luminaire will be most appropriate if you are looking to meet a certain accreditation. If we use the general lighting example (L1(B), L2 6.60) it details that a luminaire must have an average luminaire efficacy (LM/W) of 95 luminaire lumens. In a nutshell, this means 96

fletcher priest architects

Re-certification process Reconditioning processes will differ for each fitting. Contact a specialist for more information. If you are considering reselling fittings, information such as lifespan, warranties, energy usage, etc., will be required.

Ecological impact When looking at the ecological Impact of a light fitting it is very important to have the entire picture- or rather, consider the entire life of a luminaire. Although TM65 and TM66 are great for surfacelevel evaluations of luminaires, manufacturers MUST consider investing in Environmental Product Declarations (EPDs). Whereas TM65/66 are self-evaluated, EPDs are externally measured.

This means manufacturers are unable to alter numbers to make themselves appear more favourable. EPDs examine the details of material sourcing, manufacturing process, a luminaire’s life during and after installation, and it’s recycling process, including where its materials end up. This therefore provides you with the most detailed assessment of a luminaire’s ecological impact.

Space Plan 5.1 Raised access floors

Key properties Raised access flooring (RAF) is designed to provide a strong and stable platform, capable of supporting heavy loads, including equipment and foot traffic. Typically constructed from materials like steel, aluminium, or high-density particleboard with a protective finish. Designed to provide flexibility, it allows easy access to the space beneath for cable management, HVAC systems, and other utilities. The panels are often modular, enabling quick reconfiguration or replacement. Also it can be reused / relocated to different spaces if needed.

Condition There is a huge knowledge gap in the industry on the best way to recondition or preserve used RAF. Besides the assessing the panels of visual impairments such as delamination, water damage or chipping, it is hard to guarantee no impact to the strength and performance of the panel during demolition, strip out and cleaning. Transporting RAF tiles has its own challenges. Lack of adequate, climate controlled storage can cause rusting and warping that can weaken the strength and integrity of the panels.

To mitigate these challenges, clients with large project porfolios are begining to assess, store and reuse within their projects.

New ranges of RAF are now made of bio-based/ sustainable materials, up to 80% recycled materials where the panels can be dismantled to recycle different components.

Re-certification process Due to its structural requirements to be able to perform as an elevated platform, RAF must withstand specific loading requirements for safety and wellbeing, especially in high traffic areas.

There are two types of standards to measure the quality of RAF panel. PSA standards for RAF is known for its independent testing and come with a 25-year warranty and can take up to 12kN/m2 of weight. BSEN 1285 requires more technical detail but there is no independent testing and it is down to the each manufacturer to carry out tests and selfcertify. This also means no guarantee is required.

104 fletcher priest architects

Fig. 5.1

Currently no reused RAF panel is tested to the PSA standard prior to being reinstalled. Suppliers in the market refer to their reused raised access floor panel as having previously been tested to meet PSA at the point of production.

Prior to deconstruction 1. Floor panels get carefully lifted and inspected of any wear and tear.

2. Pedestals to be unbolted from stringers. Inspect any damage or broken pedestals.

3. Carefully remove stringers.

4. Tape respective fittings to each panel/batch.

Embodied carbon The production of the raised access floor is energy intensive process due to amount of steel and aluminium is used. Transport and removal also requires substantial amount of carbon.

Ecological impact Raised access flooring systems are typically made from materials like steel, aluminium, concrete, and wood. The extraction process of those materials can result in air and water pollution - and other pollution that can cause environmental degradation.

Space Plan 5.2 Carpet tiles Chapter input by Tarkett

Key properties Carpet tiles provide an aesthetic appeal and acoustic control to a space. They are made in standard sizes, making them great candidate for reuse. Typically commercial carpet tiles are made from materials like nylon or polypropylene, they’re designed to be durable, stain resistant and low maintenance.

Carpet tiles allows for easy replacement, so can be a sustainable choice for high-traffic area. Once cleaned, can be reused but due to low cost it’s hard to be sold separately and usually in bulk.

Re-using carpet tiles in commercial environments is now more difficult due to the new Building Safety Act 2023, where stringent product data is required, especially regarding Fire ratings. Majority is likely to be downcycled as carpet has low demand in the market. Although, Re-Use in the Social Housing sector can significantly improve living standards for low-income families, which adds social value.

Condition Things to look out for when considering reusing carpet tiles look out for the following: wear and tear, water damage such as mould or leaking, holes toxic glues. Historically, most carpet tiles are bitumen and PVC backed which can lead to some major considerations.

The condition of carpet tiles can play a significant role on whether they can be re-used. That said, all considerations should be made. Nylon and polypropylene, the predominant fibres used in commercial carpet tiles, are extremely durable and will rarely ‘wear out’. However, depending on the maintenance of the product some pile flattening may be apparent, especially in traffic lanes or beneath caster chairs.

Carpets must be laid with a good quality trackifier or adhesive spray. If during the first installation, the carpet tiles have been installed prior to the adhesive ‘tacking off’, this can result in a permanent bond. So, when it comes to removing the tiles, the fleece backing can remain on the subfloor, permanently damaging the tiles beyond re-usability.

Over time, spillages and temperature changes in the office environment can shrink carpet tiles, leaving gaps between tiles causing damage to the edges. Solution Dyed Nylon is the best for reuse as the colour is soaked through every fibre of yarn. Avoid reusing carpet tiles which aren’t solution dyed will fade inconsistently overtime.

110 fletcher priest architects

Fig. 5.10

By assessing the “Yield” a carpet specialist can calculate the amount of reuseable carpet tiles. Approximately 5% of carpet tile insulation consists of cut tiles - either at the perimeter, above floor-boxes, or due to creative designs. These cut tiles will need to be discarded but the remaining tiles could be graded/banded depending on their condition and stacked/ collated accordingly.

Re-certification process Currently there is no re-certification process for carpets but a report can be made by a carpet specialist who can quickly identify what % of carpets can be kept.

Embodied carbon Historically, the manufacturing process of carpets and carpet tiles is highly energy-intensive, involving the production of fibers, dyeing, backing production, and assembly. This process often relies on fossil fuels, leading to substantial carbon emissions.

The majority of major manufacturers have implemented renewable or green energy sources in their factories, which actually reduces the energy intensity / impact of the manufacturing process.

The highest impact comes from raw material extraction, as highlighted in the next section. Hence why most manufacturers are utilising higher levels of recycled content, again, to limit this impact.

Ecological impact Most carpets are made from synthetic fibres which are derived from petroleum. The extraction and processing of petroleum are energy-intensive and contribute to habitat destruction, water pollution, and greenhouse gas emissions.

Many carpets contain flame retardants, stain repellents, and other chemicals that can be toxic to both humans and wildlife. These chemicals can leach into the environment during manufacturing, use, or disposal. Check with a manufacture before shredding carpets. Cradle to Cradle certification reduces these harmful chemicals and additives being used in carpet and carpet tiles.

Space Plan 5.3 Ceiling tiles

Description Suspended Ceiling tiles are designed to provide aesthetic appeal and acoustic control. Typically the tiles are made from materials of mineral, wood, metal or resin. the suspended frames are usually made of aluminium.

Ceiling tiles are usually modular, allowing for easy installation, removal, and replacement.

Fig. 5.25

Condition FIrst thing to do when assessing a ceiling tiles is to find the product code or name of manufacture which can usually be found at the back of the tile. If a name can’t be found, contacting a ceiling specialist can help you identify the recovery potential by whether there is demand for the tile in the resale market.

If a product name is identified, contact the manufacturer as they may have take back schemes linked to the product.

Characteristics to look out for in ceiling tiles include staining or discolouration in tiles, damage or performance issues.

Water damage, cracks or holes can affect the overall performance and quality of the tiles.

Inspect the suspended ceiling frame. The frame should be easily to unscrew but be cautious of warped or rusting frames.

Re-certification process Follow the BS EN 13964 code that applies to suspended ceilings. This covered general defects such as lack of robust fixing to the soffit above, inappropriate product of the environment such as humidity or acoustic requirements.

Prior to deconstruction 1. Identify product and manufacturer.

2. For ceilings over 100m² confirm that load test to fixings are requirements.

3. Confirm whether ceiling had any special features - high humidity, fire. acoustic requirements.

4. Clarify the soffit construction with grid layouts and fixing schedules.

5. Confirm what considerations were included in the design of the support structure e.g. fire/sound insulation etc.

116 fletcher priest architects

Post-deconstruction 1. Identify any risks or change from the original design and advise site management team.

2. Frame to be unbolted with fixing location inspected for quality (no damage) to ensure it can still support the load.

Inspect any damage or broken fixing, wires or brackets.

3. Ceiling tiles to be removed carefully, inspected and stacked.

4. If elements need replacement, check compatibility with what’s available on the market.

5. Pull tests should be carried out on ceilings with an area exceeding 100m² and a factor of safety of 2 is applicable.

6. Where the ceiling is to be reused in a high humidity area or externally, confirmation of suitability must be provided in the form of a 3rd party certification which would also cover fixing requirements.

7. Fire resistance and fire testing certifications would also need to be issued if it is required in the new application. If the manufactuer can be identified early on, their records whould tall you the products properties.

Space Plan 5.4 Ironmongery Chapter input by d line

Key Properties For more enduring and hard-wearing products, most ironmongery and sanitary fittings that you will find will be made from non-corrosive AISI Grade 316L Stainless Steel. Stainless steel is chosen for its health and hygiene properties, as well as its recyclability and durability.

These properties make the products incredibly resistant to aggressive environments and allow them to have extraordinary lifespans.

Under the industry test evidence for lever handles BSEN1906, seven-digit codes relate to many categories, one of which is used, that being digit 2. Lever Handles should be tested to a minimum cycle test of 250,000; some manufacturers have pushed the boundaries to the Millions. This allows the product to have a strong LCA alongside a manufacturing warranty. Companies like d line offer a minimum of 20 years of life from the delivery of their products.

Condition Things to look for when considering reusing would be the corrosion and functionality of the wearing parts. The area that is most prone to wear an tear is the locking mechanism and the gears within. It is important to seaparte the fittings into its smaller parts to prolong its life.

D line has now offered to extend its 20-year warranty by introducing its ReHandle scheme. The programme is industry-first within its sector, allowing clients to return and have existing products serviced and returned to the building as good as new. This circular system will prolong the life of its products for up to 100 years.

Re-certification process Ironmongery requires certifications, on national levels. As long as the products are used for the purpose they were bought for, the certifications will be upheld even after reuse.

Post-deconstruction 1. Inspect the visual quality of the levers and move them to test the wear on the lock case within.

2. Unscrew the levers and remove the lock case within, take note of any rusting or breakage.

3. Store together to ensure lock case and levers stay together.

Fig. 5.38

Embodied carbon Almost 63% of operations’ carbon footprints stem from their choice of material. Stainless steel is a very resource-intensive but highly durable material, making it a great candidate for reuse. Every new product put into the world has severe CO2 impacts. By choosing to Re-handle d-line products instead of producing new ones, you will dramatically reduce the carbon footprint between 54% and 91%, depending on the product. This has been documented in 40% of d line’s current active range, which has fully declared EPDs ( Environmental Product Declarations) rather than only the mandatory A1-A3 production phase. EPDs are missing one vital information: the expected life span. D line prefers solid stainless steel AISI 316 because of its endurance and recyclability. Heavyweight increases the global warming potential, so they need to include expected life span and Re-handled possibilities. As an example, to ReHandle dline’s Lever handle, you have 4.21 kg CO2 (of 1kg of product) in the production phase, and then to ReHandle, you will use only 1.59kg CO2 (against 1kg of product)—a massive saving of 62% less emissions.

Ecological impact 90 % of the global loss in biodiversity comes from mining and processing the world’s natural ressources. Mining and quarrying, as well as manufacturing metals that are part of the majority of ironmongery’s value chain, are both dependent on ecosystem services and are both in the critical zone to danger zone with regards to nature related risks.

Prevention of downcycling is the best possible way to avoid further climate impact. d line therefore offers to service their products to renew the 20-year warranty.

Stuff 6.1 Furniture (office)

Key properties Office spaces frequently replace furniture during fit outs, leading to their reduced lifespan and high environmental impact.

Mass-produced furniture is often made from composite materials, which, if not properly considered, can have a negative environmental impact as they likely end up in landfills.

Office furniture can be reused with minimal effort and creativity.

With careful consideration, sustainable and aesthetically pleasing solutions can be achieved. The goal is to reuse or remanufacture where possible. Other sustainable options include reselling or donating furniture to charities and local organisations, which helps extend the lifespan and prevents waste.

Key sub-types Office furniture includes all movable pieces that are not fixed in place, and it encompasses a variety of types. The main categories of office furniture include: Breakout and lounge soft furniture – Often upholstered and can become damaged – Aesthetic requirements often key Meeting room furniture – Can be more unique – Aesthetics important Workstation desks and chairs – Often in large quantities – High levels of wear and tear – Note variation in product instances Storage – Often modular – Can be back or house or front of house Pods/booths – Often complex systems that can feature audio visual Consider how to handle soft upholstered furniture versus hard surfaces, the material composition, and how materials are bonded together.

130 fletcher priest architects

Fig. 6.1

Condition Set out a strong banding strategy. Consider the following: – Suitability for modern workplace environments: Is the furniture still appropriate for today’s office needs?

– Physical condition: Check for signs of wear and tear, staining, and structural integrity.

This clarity helps determine which items are suitable for reuse, which may only need minor repairs or refurbishment, and which should be replaced entirely.

Re-certification process Re-certification processes may be necessary for various types of furniture, especially when reselling or donating. For soft furnishings, fire safety tags are required, while other items may need timber certification, information on lifespan, warranties, and other relevant details. It’s advisable to consult with a specialist to ensure all necessary certifications and requirements are met.

Contacting original manufacturers can help restore and improve existing furniture, with buy-back schemes offering a way to return items for refurbishment or recycling.

Embodied carbon Furniture can have relatively high embodied carbon, especially considering their often short lifespans. Refer to product EPD’s or Overbury’s ‘Counting the upfront carbon in cat B fitouts’ report for more detail on the typical embodied carbon of different furniture items. Complex items featuring metals usually have the highest embodied carbon, e.g. phone booths and meeting pods.

Ecological impact Furniture often features multiple materials and components with complex global supply chains resulting in significant ecological impacts that are hard to trace. It is common for certifications such as FSC to be missing for certain components.

Notes

Confirm audit, listing, storage, and coordination responsibilities.

Engage with the provider to understand how waste is managed and certified.

Engage with reuse market providers early to understand their costs and requirements. Some collect the products themselves whereas some facilitate collection by others. Consider who is going to coordinate viewing, collections, goods lift booking, or storage with site works and programme.

Engage with the provider to understand how waste is managed and certified.

Engage early to understand which items have a reuse market.

Consider how to balance speed an ease with certainty over maximising reuse potential, social, and economic value.
