Do the building regulations support a zero carbon future?

Ryan John Cooksey

Main Changes In The 2022 Edition - General updates that most people do not read. - Industry jargon that the everyperson archetype doesn’t understand. - Updates that are only solving a problem now but not solving a problem of the future. - Zero effort to engage and educate all stakeholders.

- Identify the problem within the current Building Regulations and Approved Documents. - Provide a framework to help educate all stakeholders within the construction industry. - Apply a carbon negative alternative to a real world problem. - Understand how to maximise the success of nudge behaviour through a visual carbon model.

Summary

*Negotiated Practice Proposal* The negotiated practice project identifies the current approved documents’ limitations when promoting new sustainable materials. Currently, publications like these tend only to demonstrate how traditional carbon-positive materials are applied to various scenarios. For example, suppose they were to be replaced with sustainable carbon zero material. This work provides critical steps that need to be followed to push for change: 1. Present the reader with shocking facts, and educate them on alternative options. 2. Have evidence that these innovative sustainable materials meet various standards and outperform standardised details. 3. Provided visual and written guidance on applying and sourcing these materials. Combining the three would see more sustainable materials used in the construction industry. With this said, I will create a booklet that uses everyday details used in the construction industry; however, I will change the materials to negative carbon materials. With that, I would survey those in the industry if they would consider swapping materials now that there is evidence that there are alternatives. The ambition would be to bring together existing material research to provide futureproofed carbon-negative building regulations / Common details.

What Is The Proposal For This Work?

Stage 1:

Stage 2:

Identifying The problem

Education Is Key

The problem with the current building regs and accompanying approved documents does not provide any information advising the variety of available materials to the user. The initial stage of this research investigates who has the agency to take control of the matter and enforce futureproofed decision-making policies favouring a carbon-negative industry. This is not a name blaming exercise. It must be perceived as an educational piece demonstrating the lack of guidance, education, and carbon-negative material exposure, impacting the difficulty of enforcing a good decision.

This investigation highlights the surprising amount of concrete consumed within the building industry. Typically when an analysis is published, it uses technical terms evaluating large numbers. However, these numbers have been brought back to an understandable scale. This has been achieved by directly linking this negotiated practice with the Miyawaki research undertaken for the accompanying thesis project to provide the every person archetype digestible analysis.

Stage 3:

Stage 4:

An Carbon Negative Material Pallet

Implementing Nudge Behaviour

The final stage of this investigation is to provide the reader with an alternative spread of an approved document / rewritten building regulations guidance. A comparison model and details demonstrate the significant amount of carbon emissions that could be reduced if alternative materials were used. The visual comparison should allow the viewer to understand carbon at a relevant visual scale. A series of models such as these should change the perception of ‘not my job’, ‘not my problem’ when it comes to specifying, designing, constructing and using specific materials.

This research investigates the consequences of applying nudge behaviour to change the material pallet used as a default throughout the construction industry. As analysed, nudge behaviour must be taken gradually to avoid tragic mistakes, which may be caused due to a lack of material investigation, application issue or incorrect use. However, a successful process could be significant to achieving overall carbonnegative results in the construction industry.

What Are Building Regulations ? The Building Act 1984 “Generally, the Building Regulations set out the required standards for the building work. For example, a home must be insulated, but the Building Regulations do not tell you how you should do it. The approved documents give help for some common problems” (HM Government, 2020:9).

Approved Document “Approved document refers to a document approved by government that provides practical guidance on how the Building Regulations can be satisfied in some common situations. Approved documents are given legal status by the Building Act 1984” (HM Government, 2020:55).

What Are The UK Staple Building Materials & Why? This page is a extract from the group work undertaken in stage 1A of the thesis. This presents the materials visible along Dudley high street. They break down the percentage of each Material featured on the facades and categorise them into primary, secondary and tertiary. To focus on the primary materials, all 3 of them are masonry / stone-based materials that carry an extremely high amount of embodied energy. Going forward, the challenge would be to introduce zero-carbon materials and allow for acceptance as Timber products only make up 2% for secondary and 10% for thirty.

Primary

It is concerning here that the top 3 materials found on the high street are all materials that carry a high embodied energy of carbon. Any material change will be drastic, especially if these were carbon negative materials.

Tracking blame It is challenging to track who is responsible for reducing materials with a high amount of embodied carbon. The page identifies that education must be the most significant factor at each stage, should the approved documents not change their stance on informing what materials should be used.

Education system The client should be advised by those educated in the field; however, they can be as much to blame if guidance is not followed.

The client

The designer

Consultants

The builder

Education is a crucial element to implementing any new guidance. Talking to those who have left the education phase of their career will be the hardest to reach out to. This group of people would most likely prefer to maintain using the material pallet they have used throughout their career until now. To ensure that better material choices are being used, guidance needs almost to force the implementation of new materials.

The User

It is controversial to blame the user of specific infrastructure. The user, in many scenarios, has no choice in the embodied carbon within a structure. IMG: 16. Tracking blame: Creating hierarchy (Source Cooksey,R )

Existing Research When reading through publications on the subject, it becomes apparent that the most significant factor preventing the construction industry from being more innovative and future proofing itself is the lack of awareness. Unfortunately, both of these papers have similar conclusions. So this research must focus on creating awareness through shocking facts and visual engagement through models.

Response of construction clients to low-carbon building regulations. (Ozorhon, 2013) Below are some of the key sentences with in the work of Ozorhon which suggest a lack of awareness. - The project was notable for the proactive role of the client, whose desire and commitment to sustainable practices was the main driver of carbon reduction (Ozorhon, 2013:7). - The inexperience and conservative behaviour of the contractor were an obstacle in the innovation process. To overcome those issues, seminars and project meetings were held at an early stage to familiarize the contractor and supply chain partners with the process approach and construction technology involved (Ozorhon, 2013:7). - Five main themes emerge based on the findings of this study. These are the client’s leadership style, client corporate responsibility, focus on end users, repeatability of projects, and integrated teams (Ozorhon, 2013:10).

A Study of Innovation Perception within the Construction Industry. (Abadi, 2014) Abadi identify that there is a criticism towards the construction industry for its lack of innovation (Abadi, 2014:10). However it was “found that the problem with managing innovation in construction has its roots in a misconception of innovation” (Abadi, 2014:10). Adadi concludes the investigation highlighting the awareness is a prime factor to the lack of innovation which could be related directly to the lack of sustainable implementation.

Discursive model of innovation in the construction industry Here I would add cross sector engagement and awareness strategies. - Shocking Facts - Public Exhibitions - Visible Carbon models

What Contributes To The Worlds Green House Gasses? Cement production contributes towards 4% of the world’s total greenhouse gas emissions. Although cement is vital to the construction industry and world infrastructure, There are, however, in many cases, alternative materials that can be a substitute. Furthermore, these ‘new’ materials are less threatening to the world, as they tend to be carbon zero. Therefore, offsetting carbon should no longer be an acceptable solution to producing carbon. Instead, carbon should be tackled at source; in this instance, the following page aims to tackle the use of concrete within the construction industry and why alternatives are not widely used.

Investigating Fire Protected Staircases A1 Fire Resistant Class: Concrete does not burn – it cannot be set on fire and it does not emit any toxic fumes when affected by fire. Concrete is proven to have a high degree of fire resistance and, in the majority of applications, can be described as virtually fireproof.

Low Cost For medium density concrete the raw material costs are between £100-£120 per m3.

High Environmental Impact The production of CO2 for 1m3 concrete is a staggering 80Kg CO2 . Compared to other materials this is extremely high.

Pre-Cast or In-Situ The luxury when using concrete is that it can be pre-cast off site, or poured on site depending on the required situation.

Non-Toxic Concrete does not produce and toxic gasses nor smoke when in contact with flames.

Water Has No Effect Concrete is not affected by the water used to quench a fire.

Repairable Concrete can be repaired after the event of a fire.

The Importance Of Correct Material Application

!!This study does NOT aim to undermine the importance of material testing. Whilst this investigation promotes the use of new materials, any material that is being transferred for concrete must meet the fire classification for its proposed use. This study does not want to undermine the importance of material testing and correct application.

Material must aim to be within this category When investigating alternative materials, they must meet the classification required for their intended use. What seems to be apparent is the lack of testing on some of these new innovative carbon-negative materials that are emerging, making it difficult for them to be specified for use. For them to be used, there needs to be a surge in testing to allow them to be recognised as safe materials. This testing would provide confidence in their application, leading to more of these innovative materials being used in the construction industry. Due to recent events making fire classification a priority, new materials will be avoided until confidence is gained. Once the testing is completed, nudge behaviour is necessary to broaden their application. 34

Alternative Materials Meeting Requirements

The final stage of this investigation is to provide the reader with an alternative spread of an approved document / rewritten building regulations guidance. A comparison model and details demonstrate the significant amount of carbon emissions that could be reduced if alternative materials were used. The visual comparison should allow the viewer to understand carbon at a relevant visual scale. A series of models such as these should change the perception of ‘not my job’, ‘not my problem’ when it comes to specifying, designing, constructing and using specific materials.

Handrails: The handrail must be between 9001000mm from the pitch line or floor. As these stairs are more than 1000mm in width handrails on both sides are required. Table 1.11 suggests a handrail overhang of 300mm. Diagram 1.13 suggests that the hand rail must be 50mm in diameter with a clearance of 50 - 75mm away from the wall. To prevent children falling the guarding rails must not have a distance of more than 100mm between them.

External doors & frames to match existing to meet a FD-60s fire rating

Part K, Table 1.1 suggests that a general access stairs should have a rise 150 -170mm and a going 250 -400mm. These have a 150 Rise and a 250 going. The steps will have level non slip treads, 55mm in width, 50mm away from the nosing of each step. These should contrast visually (yellow). A minimum of at least 2m is required between the landing and ceilings. All electrical work required to meet the requirement of Part P (electrical safety) must be designed, installed, inspected and tested by a person competent to do so. Prior to completion, building control officer should be satisfied that Part P has been complied with.

1.20 Conventional Material Model Here is a 1.20 model of a conventional fire-protected staircase, based on the lack of material guidance in the approved documents alongside the precedence in earlier pages. Notice the lack of material pallet. There is only concrete, steel, and iron. All of which have a heavily embodied energy. Refer to the tennis court model to visualise the amount of trees required to offset the embodied carbon.

“Off-site production” This page highlights the off-site production processes of a concrete staircase. Notice the amount of wasted material required to cast the concrete. This needs to be added to the embodied carbon.

IMG: 44. 1.20 Conventional material model B (Source Cooksey,R )

The reinforcement bars also add tot he embodied carbon. (see the calculation in previous pages)

There is a waste element when working with concrete. Although the manufacturer would calculate the exact amount required per mould to avoid wastage. There is still the waste within the machinery, waste that may be spilled, and waste that they may allow for. All of this adds to the embodied carbon. The timber framework on site needs to be accounted for when calculating the embodied carbon. This was left open the model to allow the viewer to see the full process.

As with all processes there is sometimes the chance that there is a fault. This crack during drying could cause this to not be used due to the potential structural issues.

Handrails are also included within the overall carbon calculation.

Link To Thesis Throughout the thesis investigation, it has been highlighted that the amount of embodied carbon on a Dudley high street was incredibly high (see thesis 1A). During the study, alternative forward-thinking ways to retrofit and construct new structures accept no material other than carbon-negative ones. To Achieve this production of materials needs to be localised. Due to a lack of land, the Miyawaki method was introduced. From this point onwards, tennis courts are referred to when referencing the required space needed to offset co2. This creates a human scale. This study investigates the barriers to using alternative carbon-negative materials, providing detail for a carbon-negative staircase replacing a concrete structure.

IMG: 2. Conceptual thesis image (Source: Cooksey, 2022)

Understanding Miyawaki Planting The Miyawaki planting method creates a forest aesthetic in a short in a short period of time, whist minimising the area of land required. It works well by using native spices of trees and shrubs (see reteach list next page for native species for Dudley), creating a multi layered forest community. This is a solution to urban planting as the growth time is significantly reduced. Here is a solution to replanting deforested areas of woodland in a short period of time. Whilst achieving high amounts of biodiversity compared to traditional forests. This is due to its dense nature. The only constraint of this method is the cost to plant 30 times more saplings than traditionally planted.

10 Times Faster Growing A Miyawaki forest grows in 20 to 30 years instead of taking 150 to 200 years if the forest was to be planted traditionally. This is ideal for a urban environment where the need for intimidate presence is required. Also this would accelerate the carbon sequestering. (Urban Forest Europe, 2022)

30 Times Denser The seedlings are randomly planted and at high density, 20,000 to 30,000 per hectare rather than the traditional 1,000 per hectare. Dense planting encourages each plant to grow faster than the one next to it a perfect scenario of survival of the fittest. (Urban Forest Europe,2022)

Local These forests can be planted anywhere under and conditions with limited space. There are case studies where even a car park space is large enough for this to be successful. (Urban Forest Europe, 2022)

20 Times More Biodiversity Due to the increased dense of the planting there is 18 times the amount of biodiversity compared to a normal forest. Again this is down to the vast number of plants within a small area. Perfect for an urban environment where Biodiversity struggles. (Urban Forest Europe, 2022)

Participative The application of these forests can be completed by anyone with out having specialised knowledge. This means that a local scheme could inspire schools and clubs to get involved. (Urban Forest Europe, 2022) IMG: 3. Miyawaki forest, setup. DR. Akira Miyawaki (Source: Atoms, 2022A)

Reference To A Tennis Court Dr Akira Miyawaki was an expert in plant ecology. He was the man behind the Miyawaki planting that has driven this thesis so far (Canplant, 2021). I investigated if the miyawaki planting requires a particular layout to ensure efficiency. In most articles, it soon became apparent that to allow the reader to visualise an area, miyawaki is referred to as an amount of tennis courts worth planting. For that reason, it is evident that from now on, when referring to Miyawaki planting, this will be visualised using a tennis court layout.

Miyawaki ‘Tennis Court’ Miyawaki forests, when related to scale, are often referred to as the size of a tennis court. As there is a preexisting relationship between Miyawaki forests and tennis courts all of the investigations will refer to a tennis court to provide human scale. The human relationship will also help promote this idea as it allows people who have a sense of scale to compare it to. Below are two images of a tennis court in two different settings. Regardless of one interest in sport or keenness to take part, most people would be able to gauge a rough idea of the size of a tennis court as its dimensions are fixed regardless of its setting.

Offsetting Via Planting Physical Model

Industry Engagement

This model demonstrates the around of carbon to offset both a traditional concrete staircase and a stair case designed with innovative materials against both typical and miyawaki types of planting based on the Miyawaki tennis court ‘grid’.

Standard Planting

Miyawaki Planting

(Controversial Materials)

195.6m2 required to offset the traditional concrete stair case core analysed in the previous pages. When scaling this to a tennis court grid, notice the significant percentage of the area of trees it requires to offset the embodied carbon over a year.

16.3m2 is required to offset the traditional concrete stair case core analysed in the previous pages when using the Miyawaki Method of planting trees. Notice the reduction of floor space required to offset the carbon. Note that this is not the ideal solution. Using innovative materials is.

General Planting

Miyawaki Planting

41.5m2 is the ‘leftover’ space of a tennis court when comparing the two models.

(Innovative Materials)

7.4m2 required to offset the innovative material led staircase core analysed in the previous pages when using the Miyawaki Method of planting trees. A proportion of this space does not offset the carbon but provides space to grow the materials required. This is a forward-thinking solution to reducing embodied carbon in what seems to have been standardised approved documents. IMG: 52 . Industry engagement (Source Cooksey,R )

1.20 Planting Visualisation Model This model is a scale representative of the number of trees required to offset the embodied carbon within both of the 1.20 models. Notice the incredible reduction of trees required when miyawaki forests are implemented over traditional planting— also the staggering difference of trees required when using modern materials over conventional ones.

The Building Regulations 2022

ur O e v !! a e S r u t u F

Nudge Behaviour Building Regulations do not tell you how you should do it. The approved documents give help for some common problems” (HM Government, 2020:9). There is an opportunity to change the materials used in construction as there is no guidance that says that a particular material must be applied to a given situation.

Current material selection Default

Currently, the materials chosen within the construction industry are impacted by nudge behaviour. Traditional construction methods are the most common ones, meaning they are the ones that get used. As a result, they become a ‘default’.

Default

Think of it as a shop layout, with the products being various materials. Most people would not travel each aisle. They already know what they want and where to find it. New materials would not even be common knowledge at this point as people walk straight past them.

When a shop wants to promote a product, it gets a prime location, such as an entrance or the tills. However, nudging someone towards one product has consequences of the product they would have bought, which also needs to be considered.

Changing the material selection route requires nudge behaviour.

Changing the current default

Influencing change to an automatic process

Making the preferred option the default

The first step is to influence change. The first step is to present a range of alternatives and not force one single material to create resistance.

Create new habitats

When these Materials become a habit, they also become an easier sell to future projects.

Presenting Alternatives

These need to be in an obvious place to prevent stakeholder avoiding them. Exposure is key to its success. Mass use

Education

Education is required for the user and designer to apply the new materials.

Consequence of nudging Nudging can become problematic if products and materials develop issues damaging their credibility. Any new method must be thoroughly tested prior to mass use.

Public Engagement CoLab Dudley Partnership

“CoLab Dudley is an experimental form of social infrastructure located on Dudley High Street.” CoLab creates spaces for people to connect across Dudley, the Black Country, and beyond. As a result, artists, Architects, Poets, and so many more have been able to reach out to each other, creating new bridges that might never have been built without this flexible and open space.

During a thesis exhibition, I was able to speak to community members and discuss the findings of this negotiated practice investigation. The visual evidence I presented through models demonstrating the amount of embodied carbon in specific building details shocked them. I noticed that those looking at the models felt they did not have a voice in the materials selected unless they were the client. However, even as the client, those I had spoken to would not have considered alternative materials. Instead, they felt that the designer should inform them of better material choices when taking on a project. This is where the importance of nudge behaviour could significantly impact the amount of embodied carbon used within the construction industry. There needs to be a series of models such as the one I have produced here for multiple construction areas with high embodied energy. These need to be exhibited on a much larger scale at construction events. The shock factor alongside education would encourage better decisions in the future.

Those in the construction industry had split opinions, leading back to economic routes and client exploration. They realised the amount of carbon the industry produced, and most were shocked to see the vast difference in planting required to offset both models. However, they felt they could only advise and coordinate based on the brief. When asked what should be done to encourage innovative carbon-negative materials, the replies were: Education is a crucial factor to all stakeholders. This includes awareness of alternative materials. Seeing a nudge behaviour scenario would encourage some; however, the most common answer was to change policy. Having a policy instructing the use or limiting the amount of carbon that can be used would force all stakeholders to think differently. However, we discussed that in order to achieve this, there needs to be more testing to provide the industry with confidence. There was an element of caution in the room when asked if these materials were the solution to the embodied carbon within the construction industry. I found that the group’s older members felt that they were less willing to change their material pallets due to them being comfortable with the materials they have used all of their careers. On the other hand, the younger members were more enthusiastic about change. This could be related to them being surrounded by the education system when sustainability is a hot topic.

Education Sector Engagement Here i had conversations with individuals and groups of students at various levels of their study.

The discussion with the students found that they were not exposed to material creativity within the industry. This could be assumed that at the early stages in our careers, we do not have the authority to be making those sorts of decisions/design inputs. The students said the only opportunity to explore innovative materials is in the educational surroundings. However, not all of the students agreed that they had been exposed to materials as much as others. This was a correlation between unit groups. Pharaps the most effective way to ensure a blanket knowledge base is to focus on this at the undergraduate stage where all students follow one brief. However, it should be up to those regulating the industry to force the curriculum to expose all students to a hands-on, material orientated module. Also, one must remember that materials are constantly evolving, so the industry must ensure that a range of CPDs provide exposure to new materials once the student leaves the education environment. As per the pie charts students feel that the only way to enforce change is to change the law. That means an updated building regulations that aims for a sustainable construction industry.

Hempcrete Investigation

Reflection Throughout this short investigation, it was clear that there is a requirement for the construction industry to take ownership of the vast amount of carbon it produces. This study identified the problem within the industry. The conclusion to this chapter was that the current policy and legislation allow there to be an open-ended argument of whom is to take the blame for the use of carbon-positive materials. This was backed by primary research based on a visual inspection of Dudley high-street (completed within stage 1b of thesis work) and secondary data published by green space. This study highlighted that a change in the approved document wording would significantly impact the specified materials. For example, change ‘does not tell you how to do it to ‘ advising a range of junction/ material pallets’. Investigating the total embodied carbon in a fire protected staircase became the case study. However, this is only a rough, educated estimate. The calculation would need to be taken further for an accurate reading, including operational, embodied, and carbon data. Nevertheless, the figures generated were shocking and proved that action is urgently needed. Users and designers need to understand the effect on the environment when specifying particular materials. When investigating alternative materials, they must meet the classification required for their intended use. What seems to be apparent is the lack of testing on some of these new innovative carbon-negative materials that are emerging, making it difficult for them to be specified for use. For innovative materials to be used, there needs to be a surge in testing to allow them to be recognised as safe materials. This testing would provide confidence in their application, leading to more of these innovative materials being used in the construction industry. Due to recent events making fire classification a priority, new materials will be avoided until confidence is gained. Once the testing is completed, nudge behaviour is necessary to broaden their application. The investigation into nudge behaviour was the most

engaging chapter of the investigation. The public engagement: This group seemed to have a split response. Many said they would be open to seeing a broader range of materials used in construction, but others feared new materials for their testing. Due to the fire being a hot topic in construction-related news, the public wanted to stick with what they knew and had confidence in. See the industry and educational feedback on the relevant pages. This study has highlighted that putting embodied carbon into visual perspective creates conversations. The underlying problems are as follows. The education sector across all industries provides the future proof modules and assessment criteria. Ensuring that materials are fast-tracked (with precision) with new innovative carbon negative materials. Allowing materials to be used with confidence across the industry. While the most significant factor is changing how the older generations use materials and challenging what they are used to by pushing them out of their comfort zones. The next step is to reproduce similar visual studies for every commonly used area of the approved documents to create awareness. This should then be exhibited and published to drive awareness and create a surging nudge behaviour. An interactive version of the approved document would help better choices when selecting materials as a secondary exercise to this. Providing the reader with options would expand their choices, reducing the potential amount of embodied carbon within standardised construction elements of buildings.
