7.2 Standards & Sustainability CPD

“The Role of Value Standards in Sustainable Construction and Operation”

An “introduction” to relevant standards or AEC sector in relation to “sustainability” and the value they deliver.

Outline structure:

The BIM Heroes programme is looking at the relationship between “quality” (ISO 9001), “project management” (ISO 21500), “asset management” (ISO 55000), and “information management” (ISO 19650).

“Sustainability” is both a “quality” issue, and has an impact on the long-term asset value (particularly with regards to upcoming climate change initiatives, EU green deal etc.

How do these fit into “quality”, “project”, asset” and “information management”?

The sophisticated calculations and analysis required to determine and guarantee “green building” is highly dependent on “information”, as well as engaging the right people, at the right time.

It is very difficult to implement “green building” at a late stage.

What are the most important things AEC should consider?

Coins Of The Realm Crest, 88p GBE AccountsI prefer to dwell in environmental issues because sustainability is always compromised by bad economics, the way QSs run the show at the moment with:

  • Inadequate elemental cost planning,
  • based on an outline specification, not updated at full specification,
  • ignoring all the details, interfaces, etc.
  • violet price books for conventional methods and materials, that lack granularity,
  • no green methods or materials,
  • ‘value engineering’ aka ‘cost cutting’,
  • encouraging or causing substitution and surreptitious substitution
  • helping to increase the “Performance Gap” between designed and actual performance.

In the absence of a really useable definition for Sustainability, Green Building Encyclopaedia uses HERACEY™:

GBE HeraceyTM GBE HERACEY™ (Jargon Buster)

Healthy Environmental Resourceful Appropriate Competent Effective Yardstick.

If your project is addressing these issues robustly in its materials and methods of construction choices, then it is probably sustainable.

BRE Green

Unfortunately, (formerly Building Research Establishment) BRE’s Environmental Assessment Method’s (BREEAM) reliance upon BRE’s Green Guide to Specification (GGtS) are our primary tools to ‘Green up our buildings’; are a long way from enabling “Green Building” as I understand it but helps perpetuate “Less Violet Buildings” and will continue to do so until “Green Materials and Green methods” and included.

It gets worse BRE’s GGtS perpetuates Business as Usual (BAU), is reliant upon carbon credits outside of the industry to get to greenwash Net-Zero and creates barriers to use of carbon sequestering biobased materials and methods to ever achieve low carbon materials and construction.

“BIM & BREEAM”

I have limited exposure to BIM, attending a few BIM events at BRE, BIM for Manufacturers and Manufacturing (BIM4M2), one about Digital Object Identifiers (DOI) and attending one and speaking at a second ‘Green BIM’ event in Leeds; another significant one called ‘Beyond BIM’ and I have presented about BIM twice from a specifiers perspective and lectured about BIM to Architecture students.

At the second Green BIM event I presented Cycle Assessment Procedure for Eco Materials (CAP’EM) an Interreg funded Life Cycle Assessment (LCA) and Environmental Product Declaration (EPD) methodology used initially to assess 100 eco materials before EN 15804 was developed.

Another Green BIM speaker mentioned that “If we did not have to do BREEAM we could have done a greener building”, this response is repeated on many projects including some I was involved in.

My most recent exposure to BREEAM was spending weeks calculating areas of materials to record what had been designed but not to use the results to change the specification, it was already too late to change anything, now that cost plan budget was in place and restricting everything that followed.

Emphasizing the need to engage with “Sustainability” at the earliest stage in a project (before bad cost planning prevents changing anything).

Another project planning to use timber construction would not get any BREEAM points unless we switched to concrete, because BRE GGtS did not have timber school building options; so we cancelled BREEAM assessment.

I hope GGtS got or gets better or we will be prevented from going low carbon by BREEAM and GGtS.

Quality Management

My approach to “Quality Management” is “say what you do, do what you say and keep records to prove it”; don’t add any more procedures to your day.

The real challenge is to maintain the clients brief, not drop the batten at any stage of the process and not allow bad cost planning to erode their ambition to invest well in a building that performs well and facilitate their business, but now with extra focus on energy, carbon along with costs.

“Project Management”:

  • Postman Pat seeing how fast it can be done on paper,
  • Ignoring correct sequence and curing times forcing the adoption of high-chemistry fast-acting poor-environmental materials.

“Cost Management”:

  • How cheap can we do it, legal minimum conventional construction, ignoring the green obligations and green ambitions, forcing the adoption of cheap high-chemistry materials.
  • Cost plan not being reviewed between outline and full specification once we know the true scope of work.

Procurement Methods

These two disciplines Project Manager (PM) & Quantity Surveyors (QS) appear to be responsible for recommending the adoption of bespoke procurement methods:

  • That make it cheaper still and/or speed up construction on larger projects.
  • That hand over specification responsibility to builders who do not have the knowledge to do so.
  • That complicate and inadequately resolve trade contractor interfaces and design responsibilities.
  • Take an extra fee to ultimately reduce quality.

See Also:

“Asset Management”

Never having had anything to do with “Asset Management”, I can see opportunities, but what do I know?

  • Government Soft Landings (GSL) or Soft Landings (SL) requiring design teams to be involved for several years after handover to ensure the building and its services are tested and commissioned correctly, operating at optimum performance and ensuring FM staff know how to maintain them.
  • Post Occupancy Evaluation (POE) for occupants to feedback and help design teams to get the building working effectively.
  • Digital Twins (DT) including updated as-built and updatable 3D model and specification information, potentially playing the role of CAD FM Operation & Maintenance Manuals (O&MM) without the hard copy.
  • Managing & Occupying Buildings Sustainably (MOBS) one of the best resources to make a difference, sadly no longer available.

“Information management”:

  • As a Specification writer and Carbon calculator I am acutely aware for the absence of and need for comprehensive competent information including: specification, test evidence, accreditations, method statements, maintenance data, LCA, EPD, Material Safety Data Sheets (MSDS) etc. for Apps to interrogate and process with many equations.
  • Post Grenfell enquiry I know I need to be sceptical about any test evidence pre-Grenfell, we need manufacturers to be honest with themselves and get everything independently tested outside of the United Kingdom (UK) until UK test houses and United Kingdom Accreditation Service (UKAS) have got their acts in order.
  • All datasets need to be proactively kept up to date, and in the ideal world all datapoints need to be search engines interrogating the origin data every time the dataset is accessed.
  • Digital Object Identifiers (DOI) should help to keep track of the origin data, if DOI was/is adopted by Architecture Engineering & Construction (AEC) sector.
  • Construction Operations Building Information Exchange (CoBIE) & Product Data Templates (PDT) tables always presented a problem for me since there are not enough cells to post any useful environmental data, EPD AMD A2 needing 126 cells alone.
  • The best solution suggested by BIM for Manufacturers and Manufacturing (BIM4M2) was point one cell at an EPD inside a database,
  • I would suggest the cell points at a machine-readable PDF EPD and/or PDF on websites using 301 redirects and/or DOI to maintain the connection.

Inevitably there is a need to address Whole Life Carbon (WLCO2) and Whole Life Costs (WLC) services that Designers and Quantity Surveyors (QS) are not offering these without an extra fee; the tools do exist but only in the hands of a few.

  • Embodied carbon and sequestered carbon play a significant role in WLCO2 and need to inform our choice of materials and methods of construction.
  • If we want to take Low or Zero Carbon seriously and avoid greenwashing with Net Zero Carbon, we have to radically reconsider material choices:
  • No longer viable options: due to significantly high percentage of man-made CO2 comes from making these materials: (GBE Violet materials)
    • Cement, Lime, Concrete, Steel, Aluminium, Fired Clay, Plastics, Chemistry.
    • High rise using steel or concrete
  • Future-proof and viable options with either zero or negative CO2: (GBE Green materials)
    • Stone, Timber, Plant-based materials, Earth-based materials, Plant and Earth based materials,
    • Highrise using Solid Wood Systems (SWS) Cross Laminated Timber Panel (CLT), GluLam, etc.
    • Healthy Environmental Resourceful Appropriate Competent Effective Yardstick materials.
  • A whole new world that we need to get up to speed on rapidly to the point we can confidently adopt them and promote them to our future asset owners.

“Beyond BIM”

BIM technologies have been available since the 70s, but the industry has been in perpetual accommodation for the past 40 years.
However we are now finally at the eve of adaptation (BIM level 2/3)…

furthermore we now have information technologies and a global data infrastructure that will accelerate us towards evolution allowing us to remake the industry in novel, but desperately needed, ways; transforming an adversarial self-serving Construction Industry into a low cost, low carbon Built Environment industry that sustainably serves society.
(Paul Fletcher 2012)

A word of warning

  • Even Government & Non-Government Organisations (NGO) publications get it wrong sometimes, because of party political objective which may differ from the real needs; lobbying by interested parties, funding the party to get favours, bribes, etc.; first drafts are nearer the truth, but you will never see it, unless leaked.
  • Even BRE misunderstand some issues and make statements that don’t appear to be questionable.
  • AI written publications and articles may be used for marketing advantage but there is plenty of evidence that AI is a generalist when it comes to specialist subjects and AI is built on predominant business as usual published know-how unless briefed to do the opposite.
  • AI will make mistakes; well informed humans can probably spot them and avoid or correct them.

Case Study: Question Everything:

  • It is crucial to challenge the status quo, including ‘rules of thumb’ and ‘authoritative documents.’
  • The commonly cited heat loss percentages for a building’s elements (walls, floors, roofs, windows) from sources like BRE and other authorities require deeper examination:
    • When were these figures determined?
    • On which Regulations or Design Guides are they based?
    • Do they account for solar heat gains through glazing?
      • Likely not.
    • Do they consider heat losses due to glazing emissivity?
    • Window technology has significantly advanced (U values from 5 to 0.5 over the decades)
    • The building’s form factor and areas (whether it is boxy, linear, or has wings) greatly affect heat loss percentages no matter how high or low the U Value targets are.
    • These percentages may not accurately reflect the current project’s or client’s investment, performance ambitions or needs.
  • Exercise caution and do not accept guidance from authoritative documents as absolute truth without thorough scrutiny.

Case Study: Triple vs. Double Glazing

  • The addition of a third pane of glass in a window may have a larger environmental impact (such as embodied energy) during its production compared to the energy savings it provides over the building’s lifetime (such as in-use energy).
  • This can lead to a cognitive bias that discourages its use.
  • However, this is not the complete picture.
  • The exact specifications of the glass, gases, coatings, edge spacers, window frames, and installation methods can all affect the overall impact, either positively or negatively.
  • Therefore, we should not accept simple statements as absolute truth and allow them to become cognitive biases.
  • The improved temperature of the inner pane’s internal face makes it closer to the wall’s internal face temperature.
  • This minimizes noticeable temperature differences, providing thermal comfort that reduces the occupant’s need to adjust the thermostat, significantly lowering in-use energy over the building’s lifetime.

European Union (EU)

Energy Efficiency Directive 2012/27/EU (EED) and 2018 update

  • EU Directive 2012/27/EU as amended in 2018 sets rules and obligations for achieving the EU’s 2020 and 2030 energy efficiency targets.
  • With the European Green Deal (not UK’s failed GreenDeal), the EU is increasing its climate ambition and aims at becoming the first climate-neutral continent by 2050.
  • The European Commission (EC) has therefore revised the Energy Efficiency Directive (EED), together with other EU energy and climate rules, to ensure that the new 2030 target of reducing greenhouse gas emission by at least 55% (compared to 1990) can be met.
    (EC website ’22)
  • (https://energy.ec.europa.eu/topics/energy-efficiency/energy-efficiency-targets-directive-and-rules/energy-efficiency-directive_en)
  • EC are driving a reduction in-use energy of buildings; needing a radical response in levels of conductivity thermal insulation to achieve it.
  • When thermal insulation levels increase across the board and reduce building in-use energy demands considerably; then the embodied energy in the materials used to build them, grows proportionately, hence choice of building materials and methods needs to be targeted.
  • Low energy, Low carbon, Low chemistry and Low water materials including stone, subsoil, earth-based, bio-based and timber materials become very relevant in this quest.

2023     Energy Performance of Buildings Directive (EPBD):

  • Introduced the “Fit for 55” legislative package.
  • The proposal includes the following priorities:
  • Obligation for all member states to establish National building renovation plans
  • Establishment of Minimum Energy Performance Standards (MEPS), requiring the worst energy performance (non-residential) buildings to reach at least class F by 2030 and class E by 2033.
  • Promotion of technical assistance, including one-stop-shops and renovation passports
  • Introduction of new financial mechanisms to incentivize banks and mortgage holders to promote energy efficient renovation (mortgage portfolio standard)
  • Following the outbreak of the war in Ukraine, the Commission issued additional proposals, such as the obligation to ensure new buildings are solar ready and to install solar energy installations on buildings.

(Wikipaedia ’23)

  • The EPBD recast represents a comprehensive action plan to renovate the EU’s buildings, bring down energy consumption, reduce building-related emissions and reach a climate neutral European building stock by 2050.
  • Embodied carbon is estimated to account for 10-25% of the total carbon footprint of buildings.
    EC are driving a reduction in-use energy of buildings; needing a radical response in levels of conductivity thermal insulation to achieve it.
  • An especially welcome aspect of this EPBD recast is that it addresses embodied carbon and whole life greenhouse gas emissions (that is, both embodied and operational emissions).
  • Until now, embodied carbon (EC) has remained largely ignored in the EU and the building sector’s efforts to reduce its carbon footprint.

With this EPBD recast, this is set to change.

  • “This EPBD vote ensures several positive steps forward for decarbonising buildings, of which two are especially welcome to us: It will establish a harmonised framework for addressing and measuring whole-life carbon, and it will set targets for embodied carbon reduction”
  • (Bellona ID ’23)
  • “The EPBD recast represents a real opportunity to accelerate the emissions reduction trajectory for embodied carbon, and we expect to see the level of action that the Parliament has now called for maintained throughout trilogues”
  • (Bellona MA ’23)

A strong EPBD is critical to reaching climate targets

  • Buildings account for approximately 40% of the EU’s total energy consumption and 36% of its CO2 emissions.
  • Meanwhile, three out of four buildings in the EU are still energy inefficient.
  • The EPBD recast represents a comprehensive action plan to renovate the EU’s buildings, bring down energy consumption, reduce building-related emissions and reach a climate neutral European building stock by 2050.
  • Embodied carbon is estimated to account for 10-25% of the total carbon footprint of buildings.
  • Heavy industries such as cement and steel production account for a large portion of these emissions associated with the construction, renovation, and demolition of buildings.
  • (EC ’23)

What the EPBD says about embodied carbon

  • The EPBD recast sets out a requirement to both calculate and establish targets to reduce building related emissions throughout the building’s life-cycle.
  • The European Parliament position on the EPBD that was voted on, calls for an EU-wide framework for calculating life-cycle Global Warming Potential (GWP), and for Member States to publish roadmaps that introduce limit values and targets on life-cycle GWP.
  • Each Member State must develop national building renovation plans, including renovation targets suited to each country’s building stock and needs, and illustrate how these national targets are to be met.
  • By calling for this, the EU is ensuring that high quality data on embodied carbon will be widely available to the myriad of actors in the buildings sector.
  • Coupled with the clear signals provided by targets, this information could help trigger a scale-up of the production and use of low-carbon construction materials.
  • In this sense, it is also important for the EPBD to be aligned with the on-going recast of the Construction Products Regulation (CPR).
  • (Bellona Europe ’23)

2024     Energy Performance of Buildings Directive (EPBD):

The latest amendment to the recast Energy Performance of Buildings Directive (EPBD), approved by the European Parliament mandates significant enhancements in building energy efficiency across the EU. (Not UK)

Here are the key impacts and important dates:

New Real Estate:

– Zero-Emission Buildings (ZEB): By 2030, all new buildings must be zero-emission, characterised by high energy performance with the remaining energy demand met by renewable sources.

– Enhanced Building Codes: New constructions must comply with stricter energy efficiency standards, incorporating advanced technologies such as high-performance insulation, energy-efficient windows, and renewable energy systems.

The whole life-cycle emissions of buildings will be considered, starting with new buildings promoting sustainable building practices and materials from construction to demolition.

Existing Real Estate:
– When buildings undergo major renovations the energy performance of the building or the renovated part thereof is upgraded in order to meet minimum energy performance standards.
– Member states shall address, in relation to buildings undergoing major renovation, the issue of indoor environmental quality, adaption to climate change, etc.
– Member States shall introduce a scheme of renovation passports based on the common framework
Key Dates:
– January 2028: Public buildings must meet ZEB standards. (GBE: no not Net Zero Carbon)
– January 2030: All new buildings must be ZEB (GBE ditto)
– October 2023: United Kingdom (UK) Conservative Government abandon or postponed all ambitions
Financial Incentives and Support:
Increased financial incentives, grants, subsidies, and tax breaks are available to property owners to offset the costs of energy-efficient renovations.
Integration of Smart Technologies:
Encourages the use of smart technologies and automation systems to optimise energy use in existing buildings, including smart meters and energy management systems.
The EPBD aims to reduce carbon footprints, save energy costs, and improve living conditions, driving the EU towards a climate-neutral economy by 2050.

  • Direct to shareholders without improving services?
  • The amount of money loaned (billions) matches the amount of shareholder payouts, not representing profits after a job well done.
  • Government voted that water utilities can pollute waterways, waterbodies, beaches and seas with raw untreated sewage with associated flotsam, in dry conditions as well as rainy conditions associated with combined sewer overflows when excessive surface water drainage combines with foul sewerage.
  • Heavily polluted rivers but gill breathing mammals and fish at risk of asphyxiation.
  • Environment Agency are underfunded effectively nobbling their policing role.
  • Once caught out and improvements demanded by public objections Water utilities claimed they will have to increase consumer bills to pay for improvements
  • Enabling more income from consumers to be distributed amongst shareholders?
  • Immediately after this issue identified (and resolved?) government voted to permit housing developers to pollute waterways.
  • Housing developers share value skyrocket overnight, shareholders benefit.

Greta 1st School Strike for Climate

Global Climate Strike London 200919

Not the truth, not the whole truth and nothing but not the whole truth

  • Dictatorship: Boris/Liz/Rishi & Home Office politicians: drive to outlaw all anti-government policy protest.
  • Police instructed to use kettling and/or arresting thousands of peaceful protestors.
  • One Extinction Rebellion (XR) Architect and peaceful protestor arrested and convicted ran the risk of being struck off for life by Architects Registration Board (ARB)
  • ACAN protest outside ARB office seeking clarity on this issue; ARB “peaceful climate protestors will not be struck off”.
  • Judges, instructed by politicians, to ban the whole truth: defendants not permitted to argue Climate Change drive their actions!
  • Juries reminded by green advisers they can vote based on their own conscience, moral judgement and ignore the judge’s instruction.
  • Some court cases thrown out by climate concerned jurors.

Do you think being better informed will help with persuading Clients to engage

  • Yes
  • Government legislation or target dithering or yoyoing prevents persuading clients
  • No
  • Others not listed here, please record in comments

Do you feel Government could be doing more to encourage engagement?

  • Brexit appears to be enabling Government to wriggle out of responsibilities
  • Government publishes without apparent business consultation nor dissemination activity
  • Government speaks with forked tongue, says one thing then acts differently
  • Business Link like organisation could have helped with dissemination
  • Supply Chain Sustainability School (SCSS) could help with dissemination
  • Construction Industry Training Board (CITB) should help training skills
  • We need to get on with it and ignore Government until it is updated to serve the majority.
    • July ’24 update, it changed colour, let’s see if it can serve the majority and environment.

    • Method: Normalising to Euronorm (EN) 15804:2012, over last decade +Amendment (AMD) A1 2013 +AMD A2 2019
    • AMD A2 became mandatory for EPD in 2022, therefor all EPD must be AMD A2 by 2027
    • All new LCA EPD must be in AMD A2 format
    • AMD A2 aligned EPD with European Commission’s PEF to avoid duplication
    • Product Environmental Foot printing (PEF) because LCA EPD has been hijacked by the violets
    • AMD A1 and AMD A2 EPDs are incompatible and should not be compared
    • EPD platforms and carbon calculators need to be updated to AMD A2
    • But most EPD are AMD A1 and all must be updated to AMD A2
    • Manufacturers will update their EPD but generic materials might get left behind
    • Manufacturer’s Associations/Federation may need to fund generic materials updates?
    • Over a period likely to be 5 years long during which EPD are not comparable
    • Plays into the violet’s ambition that EPD should not be compared
    • Sequestered Carbon Method, outside of EN 15804 system boundaries
    • Biogenic carbon is addressed by EN 16449:2014
    • Manufacturers: 10,000 EPDs in market, plenty are in construction materials
    • But most are AMD A1 and all must be updated to AMD A2
    • 5 year cycle of regeneration as EPDs expire or products improve and manufacturers want to declare it
  • LCA is a broader set of impacts, but we still need to focus on:
    • Embodied carbon ≈ CAPEX Capital Expenditure
    • Sequestered Carbon, Biogenic carbon, Timber and Bio-based materials, not Fossil carbon
    • EN 16449:2014 (we might not be in EU but standards are private enterprise in United Kingdom (UK) but cited in regulations)
    • In use carbon (IUC) ≈ OPEX Operational Expenditure
    • Whole Life Carbon (WLC) ≈ TOTEX Total Expenditure
    • Heathy building: Low chemistry, low plastics, low off gassing,
    • Low embodied water and embedded water
  • Platforms including OneClick LCA cannot show AMD A1 & A2 LCA or EPD datasets in the same place at the same time
    • Many viewing platforms present A1 EPD
    • Platforms are required to upgrade to an A2 viewing platform
    • Currently many A1 EPD can be seen together,
    • Very few A2 EPD exist but can only be seen with other A2 EPDs
    • A1 and A2 cannot be seen together
    • Until many A2 arrive A1

Environmental Assessment Methods: Drive change?

BREEAM driven via GGtS & GBL

  • Green Guide to Specification (GGtS)
    • ‘BRE-Green’ not ‘GBE-Green’ Green Building Encyclopaedia (GBE)
    • ABC ratings should be relegated to DEF and ABC are missing
    • Industry average Generic Materials (no incentive to improve)
    • 1200 Readymade Elemental Assemblies (probably not what you are doing)
      • But exclude accessories
      • High energy and high carbon metalwork and plastics
      • So gives a completely false rating
    • Bespoke assessments (BRE take their time)
      • 400 more assemblies added? Still not green enough
      • Green Materials missing
      • Green Methods missing
      • Low carbon materials and methods missing
      • Negative carbon materials and methods missing
      • Bio-based materials missing
    • GreenBook Live (GBL) Products directory
      • Previously mostly plastic or bitumen backed carpets (BRE Green!)
      • BRE Environmental Profiles (EP) predating EN 15804
      • = EPD once recalculated to EN 15804

BREEAM Infrastructure (Pilot)

  • Like all BREEAM Tools
    • it records what you did,
    • not change the way you did it
    • “If not from BREEAM, it could have been greener”
  • High Speed Rail Link Phase 2 (HS2) destroys easy targets (whilst COVID lockdown hid evidence)
    • Many Sites of Special Scientific Interest (SSSI)
    • Many Ancient forests
    • 400-year-old free standing specimen tree felled for a maintenance slip loop road
    • designed at 1:50,000 scale that should have been rerouted 100 m at 1:1 scale
  • BREEAM completely fails on behaviour change.
  • BREEAM with Green Guide to Specification: completely fail on low carbon construction

  • Previous CEEQUAL V5
  • 15 years, 1300 trained assessors,

  • National Rail Specification? Nothing yet

Highways England:
Department of Transport (DoT) Standards

  • National Road Specification?
  • Guidance:
  • Missed opportunity?
    • No promotion just updated and reissued
    • Example recycled content permitted, but nobody knew
    • What about embodied carbon? Nothing yet

Missed past opportunities:

  • WRAP’s Aggregain website: no longer funded, so gone.
  • But some of WRAP outputs addressed recycled content, emphasised higher % over competency.
  • Earth Exchange website: exchanging clean subsoil between sites, also gone.

  • Less Energy datasets
  • Update funded by infrastructure:
    • Heathrow, Rail Safety & Standards Board (RSSB), Environment Agency (EA)

    • Bad Cost planning?
      • Especially in Infrastructure projects
      • Bankrupt construction industry? Financially and morally
    • Crippled Supply chain?

      • Mental Stress prevails?
      • Suicide rates are high.
    • Public consultation 2023
      • Listened to Violet sector looking after its interests
      • Over complicated carbon sequestration to point it cannot practically be taken into account
      • Is effectively abandoned timber as a solution to climate crisis
      • But despite that architects that care and know better, do better.
    • Edition 2 February 2024
      • More detailed, more solutions and more challenging
      • Reporting table: Includes but makes sequestered carbon difficult to address
      • Despite EN 15804 setting a consistency standard for all countries
      • RICS makes LCA EPD inconsistent with other countries LCA EPD outputs
      • Violets have their way again; nothing can be compared.

Contracts & Procurement:

  • Government does not want to collect enough tax from big business and wealthy individuals so introduced a different way to pay for infrastructure and buildings:
  • Private Finance Initiative (PFI) or Private Public Partnership (PPP)
  • Letting private Contractors build and private Facilities Management (FM) enterprises make £ millions, maintaining them for 25 years then handing the buildings back to Government.
  • If a bid can cost a £1m in professional fees there has to be a major incentive to make a bid.
  • So lucrative that most Constructors expanded into FM others gave up contracting and converted to FM enterprises.
  • Very little joined up environmental thinking.
  • Weak on specification and failed to control impacts of materials choices.
  • Short life materials and 25-year long-life warranties and premiums to pay: the straw that breaks the camel’s back, helping to bankrupt UK National Health Service (NHS).
  • Failure Case studies:
    • 50 km (per hospital) of capped and coved Poly Vinyl Chloride (PVC) skirtings that fails when the phthalate plasticisers in the PVC polymer migrates into the adhesive immediately destroying its ability to stick, creating voids for bacteria to reside in, inside brand-new hospitals.
    • Or building school with external masonry cavity walls without wall ties.
    • Or building with Reinforced Autoclaved Aerated Concrete (RAAC) floors and roofs,
      • Unreinforced Autoclaved Aerated Concrete (AAC) is used to make insulation concrete blockwork
      • Aerated Concrete (AC) is used insulated ground bearing floors
    • The latest thinking is that PPP will help to fund replacement of RAAC, which probably was adopted for the first time in PFI or PPP projects in the first place.
    • Initial applications for RAAC were precast insulating wall panels carrying its own self weight and where an external rainscreen cladding with waterproof membranes and internal lining with vapour barriers may have been used.
    • PFI school contractors appear to have adopted RAAC in place of Precast Reinforced Concrete planks as a loadbearing floor or roof; where its moisture permeability makes it vulnerable to leakage wetting, reinforcement corrosion and frost damage, all predictable issues.
    • If thorough and competent scrutiny of the specification had occurred, this should have been avoided.
    • But bad violet cost planning probably forced the hand and there was little will to veer away from low costs.
    • PFI and PPP is superseded by a better system in Scotland.

Sustainable Engineering Specification?

  • Engineer’s use Specification Templates
    • Who maintains and updates the template with current good practice, new materials development
    • How often is it updated?
    • May well need a radical update to keep up with cement and concrete low carbon developments
  • New cover for each job
  • List all materials and techniques Green and Violet
  • Permit greener options but do not require it.
  • Little or no editing to be job specific.
  • Rely on drawings to specify which, where.
    • Are the Engineers getting Continuing Professional Development (CPD) seminars to keep them up to date with the specification template?
    • Can they tell the difference between green and violet?
    • Are they choosing low impact or being pushed by Professional Indemnity Insurance (PII) towards Business As Usual (BAU)?
    • Are they choosing what they know?

Materials

Concrete Mixing Plants

  • Have two cement silos.
  • Ordinary Portland Cement (OPC) & Ground Granulated Blastfurnace Slag Cement (GGBS)
    • waste from iron ore from steel production
  • GGBS is significantly lower Carbon than OPC
  • GGBS is lower cost than OPC

They save money by blending:

  • OPC and GGBS
  • A slower set but same ultimate strength
  • Just enough GGBS so you won’t notice
  • OPC drives GGBS hydration to maintain 7 & 28 day strengths
  • Colour difference: OPC: cold grey, GGBS: Warm grey.
  • As UK steel production shrinks GGBS will become rationed.

Green Building Calculator (GBC) (by the author of this article)

  • In the absence of career competent architectural education there is a need for design and decision tools to fill some of the gaps.
  • In the post-Grenfell world with the impending Regulation tsunami demanding competence not just awareness.
  • It’s no good just doing scattered carbon calculations for parts of the building:
    • Structural Engineers doing frames and slabs
    • Façade Engineers doing cladding and curtain walling
    • Architects doing building fabric
    • Interior Designers doing finishes and furniture
    • Service Engineers doing Mechanical Electrical & Plumbing
    • Landscape Architects doing hard, soft and wet landscapes
    • Civil Engineers doing Infrastructure
    • And loads being missed out because somebody assumed the other was doing it
    • See UK GBC NZW Low CO2 ambition above
  • We need to become carbon-literate and chemistry-literate to be able to intuitively make environmental and healthier choices.
  • Calculators need to address:
    • winter heating and summer overheating, and future facing
    • form factor,
    • Choose and apply: legal minimum regulations v design standards v campaign targets
    • U values of all elements, and sub-elements, new build and retrofit
    • Competent appropriate materials offered in all applications
    • k value, density, specific heat capacity, format and competent application of insulation materials
    • Condensation check
    • From hours of conditioning (heating or cooling) through to design life
      • (normal = UK 60 years = EU/INT 50 years)
    • Fuel choices, carbon factors and fuel costs
    • Energy, carbon & cost of building and energy, carbon & cost in use

Green Retrofit Calculator (GRC)

  • In addition to GBC features:
  • Ready-made house types: based upon UK English and Scottish House Condition Survey and accommodate variations
  • Survey form for other buildings and bespoke
  • Elemental U values for existing, previous and proposed interventions
  • Risk assessment based on existing building, previous and proposed interventions
  • Scenario comparison: Existing + Previous interventions + New Interventions + Options & Alternatives

Green Interior Calculator (GIC) (proposed for development)

  • In addition to GRC features:
  • Furniture types and bespoke furniture
  • Carbon (EPD) and Chemistry (MSDS) analysis of materials

Green Insurance Repair Calculator (GIRC) (proposed for development)

  • Scope 3 Carbon emissions in supply chain
  • Emissions for labour, plant, materials, waste, vehicles

Other ambitions include:

  • Glazing, Flooring, MEP Services, Landscape, Infrastructure, etc.
