How to complete an LCA for BREEAM 2018

life cycle design

From specific products to whole project analysis, LCA is taking off globally to help project teams quantify and improve environmental performance to meet global and national impact reduction targets.  BREEAM have recognised this and the new updates to BREEAM 2018 place a heavy emphasis on the LCA approach.

  • Up to 2 credits available for completing an LCA using IMPACT.  Credits awarded depend on performance against the Bre benchmarks.  Credit is awarded at Stage 4 once detailed design information is available
  • Up to 2.66 further credits available for Superstructure options appraisals during RIBA stage 2
  • Up to 1.33 further credits available for Superstructure options appraisals during RIBA stage 4
  • 1 credit available for substructure and landscaping options appraisal during RIBA Stage 2
  • 1 exemplary credit available for services options appraisal during RIBA stage 2
  • 1 exemplary credit for alignment with LCC
  • 1 exemplary credit “3rd party verification”

Understandably this is a big step change for many design teams used to the traditional Green Guide approach.  However, significant changes are enabling LCA to become common practice for designers, including:

  • newly available life cycle data,
  • user-friendly and cost-effective software platforms,
  • collaborative development of international standards and increased transparency,
  • integration with Life Cycle Costing for economic and environmental accounting
  • LCA legislation in planning policies, EIA and government incentives,
  • increasing uptake in academic research and universities curriculum
  • professional leadership and technical know-how;

The heavy weighting of credits for Stage 2 analysis encourages design teams to consider the life cycle impacts of their buildings at early design stages. (BREEAM require evidence for this to be submitted pre-planning). Applied at project concept stage, LCA provides insight and huge opportunities for life cycle environmental and cost improvements. Performance targets can be set during project preparation and brief, “what if” scenarios are used to assist design development and a detailed report will consolidate results according to project specifications. This “disruptive” practice in sustainable design will hopefully unlock the further potential to decarbonise buildings and infrastructure.

LCA Stage 2: Often there will be limited information available at pre-planning and a limited appetite for spending money on LCA.  This is where eTools powerful template system comes into its own.  Our whole building LCA templates allow for quick, rough and ready LCA analysis.  With only basic information the template will fill the gaps using industry average defaults, this can be analysed for hotspots and design options and updated with project specifics as the design progresses through to Stage 4.

Benchmarking:  Although the benchmarking credits do not need to be submitted until Stage 4 the benchmarking report is fully automated from eTool.  So the number of likely benchmarking credits can be analysed early on and design options can be prioritised based on what provides the greatest uplift.

LCC Alignment: Aligning the LCA and LCC is of vital importance for effective LCA work. Quantifying the costs of improvements will help teams prioritise how to get the best environmental gain for least capital spent. With our recent cost functionality, it is a simple step to extract LCC results from your LCA model and report for the Man2 credits. Simply ensure you report the same options in your LCA submission as you do in your LCC reporting.

Substructure and Landscaping:  Our templates system covers all of these elements and they can be added to the model with basic information (eg depth and width of piles or area of macadam road).

Services: Services require a separate model because the Bre IMPACT data cannot currently be used to model services.  We are currently working on alternative datasets that will do this.

3rd Party:  Our certification service is provided to all users projects completed commercially as part of our standard software offering. During the certification process, a senior eTool LCA practitioner is made available to the project and will undertake all quality checks defined in BREEAM.

For further detail on how to run reports for Breeam 2018 from eTool please see our support video here.

To continue supporting this process, eTool have released the eToolLCD Enterprise subscription. Embedding LCA at an organisation level has become easier and will provide added value with centralised ownership of LCA models, inter-company collaboration for integrated design and an unrestricted number of read-only users. 

Designers that have increased demand for LCA services can choose the new Specialist subscription to work on an unlimited number of projects with a fixed software cost.

We are working hard to continue bringing innovative solutions and we are improving eTooLCD with additional life cycle inventories, enhanced Life Cycle Costing functionality and many others that you can check out by creating your account at eToolLCD.

eTool have produced a number of different articles on integrated design using LCA including latest materials comparison, reporting efficiency and additional revenue by selling LCA services. Help us by sharing with friends and colleagues.

Life Cycle Design of Buildings: An Introduction & Application in Green Star (recorded webinar)

The use of Life Cycle Assessment (LCA) is gaining greater recognition in sustainability assessment. An LCA credit is embedded as a core credit in the Green Star rating tools Design and As Built v1.2, Interiors v1.2 and Communities v1.1.
Points may now be easier to achieve for some projects provided there’s early engagement of LCA consultants. Points allocation have been adjusted with operational energy reductions capped. Further Additional Reporting initiatives were added with extra points available.
– Design and As Built v1.2 – up to 7 points
– Interiors v1.2 – up to 19 points
– Communities v1.1 – Up to 5 points

This recorded webinar covers the basics of LCA, the eToolLCD software, and how it applies to Green Star – LCA credit.

New eToolLCD Pricing

eToolLCD subscription prices have been recently updated. Please read on for more info.

Why have we updated pricing?
For a few reasons. We have noticed a strong trend where our subscribers are each (on average) conducting more LCAs per year. We wanted to ensure our pricing remained competitive and predictable so have added some plans that reduce the per project fees. For example, the new specialist subscription has no per-project fees and the new enterprise pricing gives a 40% discount on per-project fees. In addition we wanted to simplify our offering and hence dropped our “Freelancer” plan.

How can users benefit upgrading to new plans?
As well as reduced per-project fees the new Enterprise subscription and the updated Specialist subscription include new functionality with improved collaboration, reporting, user admin/management and the soon to be released Revit Plugin. Consultant subscribers will also enjoy additional Life Cycle Cost functionality, and automated BREEAM 2018 reporting that’s coming out soon. All round eToolLCD is getting better for users, and watch this space, more to come!

Why the US Dollar pricing?
The use of eToolLCD is expanding globally and some of our users provided feedback that the Aussie $ pricing was a unusual. So we’ve now set our pricing in a currency that everybody recognises.

How will this affect existing subscribers?
eTool is “grandfathering” existing eToolLCD subscriptions so you won’t lose any functionality or have to pay any more or less until June 30th 2019 when we’ll ask existing subscribers to migrate to one of the new plans. Please note, if your subscription lapses you’ll need to transition to a new plan.

Who is the new Enterprise Plan for?
Organisations that have a number of consultants using eToolLCD, or developers and builders who want to track the performance of their portfolio is projects. We have a range of features for this plan that will make Life Cycle Design very easy, scaleable and transparent for these businesses. Please get in touch if you’d like more info.

Project Stage and LCA Processes(1)

Life Cycle Design is gaining greater recognition in Green Building and Infrastructure rating systems. Early engagement of LCA consultants will identify impact hot spots and help prioritise improvement strategies that are most cost effective. LCA credits may be easier to achieve as a result of engaging early. 

To continue supporting this process, eTool have just released the eToolLCD Enterprise subscription.

How to Price Construction Life Cycle Assessment Services

With the general interest in LCA growing rapidly and ramp-up in LCA credits within Breeam NC 2018 imminent, many of our users are asking us how much work is involved in completing an LCA, how long it takes and what they should be charging their clients for undertaking the work. eTool has always maintained a very transparent approach towards our own pricing structure and we thought it might be useful to share our thoughts on pricing LCA consultancy services.  We have highlighted 3 different approaches for costing an LCA described in detail below.

  • Value to the Developer –  This is the approach eTool take for costing an LCA.  We charge a fee that attempts to reflect the value that the LCA provides to the design team, developer and the planet.  In some circumstances, the consulting work to deliver an LCA of a large apartment block may actually be similar to that of a single house. However, the LCA will provide learning outcomes that can have a much higher impact in terms of environmental benefits or life cycle cost reductions.  Let us take the example of two projects in the UK, a large apartment building with 120 dwellings and a construction budget of £30,000,000 and a small single dwelling development with a budget of £150,000.   An attractive strategy identified in the single dwelling may reduce greenhouse gasses by a total of 100tCO2e and also save the occupants £5,000 in life-cycle costs.  In the apartment building, however, a similar strategy may save 10,000tCO2e and over £1,000,000 in life-cycle costs.  Similarly, if a developer has a specific environmental target, the stakes are much higher in the apartment project.  The cost of abatement is quite critical and can severely increase capital costs if not well understood.  For example, if a 50% reduction of life-cycle greenhouse gas emissions is sought, employing the best strategies on the cost abatement curve may cost the developer £500,000 by targeting the lowest cost of abatement, but employing strategies without this consideration may cost them £1,500,000 to achieve the same environmental outcome.   So regardless of the level of effort in the two projects, there’s a much higher potential value that the apartment stakeholders get from a quality LCA and LCC study.  We like this approach as it aligns the consultant’s motives with both the planet and our customer.  The consultant’s role is to deliver value, so a higher fee should yield more value.  This may be realised by greater effort in identifying low impact strategies and optioneering to ensure meaningful reductions in environmental and cost impacts.
  • Bottom Up – Determining the billable hours to complete the work and charging the consultants the hourly rate plus a profit margin.  The total hours spent on an LCA can vary dramatically depending on the following:
    1. Design stage.  The more detailed the information the more complex the modelling becomes.  A “Target setting” LCA will have no more than a design brief as input information and a basic model may take an hour to complete with another few hours of optimising strategies, a stage 2 LCA may have more detailed information available and take half a day to a day and a detailed stage 4 LCA may take a further day to 2 days to complete.
    2. Quality of information available.  Often the most onerous part of any modelling process is gathering the information required.  If this is orderly and well organised then completing the LCA should be very simple. Cost plans and BIM models can contain good levels of information but are these freely available or will it take months to track them down? Are they complete or missing crucial bits of information? Sometimes it can be quicker and easier to measure up drawings manually rather than spending days chasing down an elusive bill of quantities which may not actually exist!
    3. Design Team Engagement. How involved are the design team in the LCA process?  Will they require optioneering for many small details in the design or are they only interested in some basic high-level results?  More engagement is great and very rewarding for the LCA practitioner but can take time.  If the client is only looking for the bare minimum required to award credits under BREEAM then the LCA may be completed very quickly using the eTool automated reports.
    4. Project Management and Margins.  You want to leave room in the scope for unexpected design changes, complex design elements and of course margin. Don’t forget that for LCA to become mainstream we all want this to be a profitable exercise as well!
    5. The LCA software that you use! Choosing the tool most appropriate for your task is of course very important.  For simple embodied carbon calculations on a single material then a simple spreadsheet (or open use eTool) would suffice. For a full whole-of-building-whole-of-life LCA with multiple environmental indicators then dedicated tools will be far more cost and time effective.  Our door is always open to help you understand the full functionality of eToolLCD. Our unique template system, strategy and option recording and automated reporting are just a few features that enable not only the quick building of an LCA model but detailed and in-depth design analysis for effective feedback to the project team.

  • Top down: What is the market rate for delivering the LCA?  Often it is a case of testing the waters to understand how much the market is willing to pay for the service and matching the price and level of work accordingly. We have seen practitioner LCA quotes ranging from £3k to over £30k!!  If the user is really enjoying the LCA work they may match the price to be competitive with whatever alternative BREEAM strategy is being considered. Considering BREEAM for example, any design effort that equates to over £2,ooo per credit is often considered a costly strategy (project dependent).  Can your competitors deliver the LCA for this fee if so what added value could you bring beyond their offering?  Alternatively, consider how can you streamline your service to get your client excited about engaging the power of LCA no matter the design stage.  For example, we targeted early stage design with a “Target Setting” LCA service which costs under £2000 and is aimed at very early stage design feedback.  Developers are happy with that service but would be very reluctant to engage in a full LCA study that early in the project.  We can deliver this service to an acceptable accuracy by employing whole building templates and high-level strategy optioneering.  The design team gets quality, quantified feedback on possible low impact strategies and can embed these in the early geometry.

Determining the fee is of course only half of the story.  Making sure the client understands the value that the LCA is bringing to the design service is equally important.  A client who understands the true benefits of LCA; a performance-based design which is driving innovation to deliver quantified savings against science-based targets, is the client you really want to work with! For more on adding value through LCA take a look at my blog post and Henriques webinar.

Alignment with eTool

General Approach

eTool are excited to see the progression of the LCA credits within Breeam. LCA is fast becoming a mainstream aspect of sustainability and is seen in the construction industry as the future of good environmental performance.  Embodied or capital carbon represents approximately 20% of total UK building emissions, LCA therefore will need to form a vital role in tackling climate change and meeting the Paris commitments. Within the industry landowners now recognise the importance of LCA and are requiring it to form part of the design process as do developers such as Land Securities and infrastructure projects such as HS2 many European countries (Holland and soon France are legislating LCA across all buildings).

The general approach of the new materials section and emphasis on using LCA to improve environmental performance from the design outset should be applauded.  eToolLCD was built with the primary intention of informing design outcomes and getting involved as early as possible, when we have the greatest number of opportunities available for improvement. By building an LCA models, analysing recommendations and presenting results we have influenced a reduction of over 500,000 tCO2e on our projects.  The high volume of LCAs that we produce has allowed us to form an extremely efficient workflow within the tool and we look forward to further helping design teams quantify and improve their building

The full 10 credits can be achieved using eTool by anyone with some basic construction knowledge. Our existing features align perfectly with the credit requirements.

Stage 2 analysis:  Often there is a shortage of information available at stage 2 to undertake a full LCA.  However, we have always believed that these are the key times to deliver LCA analysis when the big structural decisions are being made and opportunities for improvement can be analysed.  That is why we built our unique template system which can provide very detailed LCA analysis using minimal information.  Our templates for entire wall and floor make-ups contain well-researched assumptions to fill any gaps in quantity information.  These can then be updated as the design progresses.

Optioneering: Another key component of eToolLCD is our recommendations reporting.  There is little point in building an LCA model if you are not going to try and improve the design outcomes or present lessons to the team, this is where the fun really begins!  We have a public library of recommendations that is building and improving with every new job and new suggestion that is proposed.  The library has groups of different recommendations that can be applied in bulk – high cost, zero cost, shell only, energy etc).  The user can record any change that is made to their model and report how they affect the impacts both environmental (CO2, water, acidification, ecopoints etc) and monetary (£, Euros and $).  The team has a simple shopping list that can be prioritised based on what provides the greatest environmental improvement for the least cost.

Reporting: Nobody wants to spend their time copying and pasting graphs and tables into reports formatting, issuing, repeating.  This is time that could be much better spent digging deeper into our LCA work and finding recommendations! We now have several reports automated directly out of the software that provides information and results in an easy to follow format. These reports are automated from our LCA models as standard and will, of course, be fully compliant with Bre evidence requirements. We are continually working on improving the reporting for our users and will continue to improve on the presentation of the LCA work

LCC Alignment: Aligning the LCA and LCC is of vital importance for effective LCA work. Quantifying the costs of improvements will help teams prioritise how to get the best environmental gain for least capital spent. With our recent cost functionality, it is a simple step to extract LCC results from your LCA model and report for the Man2 credits. Aligning the LCA with the LCC means that a full LCA will need to be completed including all elements within the build – finishes, operational energy etc . These are beyond the scope for the Materials credits however they can be easily added to a model using our template system.  Including operational energy in particular, can raise some very important design decisions. Do the savings from thermal mass or triple glazed windows make up for their embodied impacts, would more carbon be saved on spending 1k on solar PV or 1k on a timber roof, this is when LCA becomes a very powerful tool?

3rd Party:  The 3rd party verification is a great inclusion. Recent publications from RICS (Whole life carbon measurement: implementation in the built environment) suggest that there can be a large variance in results of LCA studies.  A 3rd party verification will not only improve the quality of individual LCAs but also encourage greater learning with the LCA community feeding back to each other improvements to processes and design options. eToolLCD has over 2000 registered users and eTool have certified over 300 full building LCA project.  Our certification service is provided to projects completed by commercial users as part of our standard software offering. During the certification process, a senior eTool LCA practitioner is made available to the project for the purposes of:

  • Assisting the LCA team with completing the study in compliance with relevant standards (Breeam LEED etc)
  • Reducing the risk to and elevating the professionalism of the users LCA service by peer reviewing their LCA study to ISO 14044 standards.
  • Assisting the LCA team with challenging concepts or modelling requirements.
  • Improving the LCA teams efficiency in completing LCAs using eToolLCD
  • Providing the LCA team with potential strategies that may be worth considering to reduce the impact of the design.

The certification system ensures a consistent, high quality of LCA studies is produced from the eToolLCD software. We will add to the certification checks those listed by Breeam such as review of total quantity data.

eTool hold the view that, if anything, the new credit offering does not go far enough and there exists further potential to deliver performance-based design.  The optioneering is a vital component of LCA work, however, further credit should be weighted towards the benchmarking.  As it stands a theoretical 100% timber building (which has zero CO2e impacts) would achieve the full 10 credits and an average building would achieve somewhere between 8 and 9 (depending on the benchmarking outcome).  There is opportunity to give more weight to the benchmarking performance which should be taken now, the climate catastrophe clock is ticking!

The new revision is by all means a positive step in the right direction.  Further detailed comments on the credit methodology (we encourage everyone to provide their own comments to the Bre) are shown below.

Further Improvements

3rd Party

 “A suitably qualified 3rd party (see Definitions on page 294) shall either carry out the building LCAs or produce a report verifying the building LCAs accurately represent the designs”

One area that requires careful consideration by the Bre is who qualifies as a 3rd party.  The definitions communicated by the Bre state that anyone who has not consulted on the design is a 3rd party.  Given the LCA work will include optioneering and will often be completed by the Breeam/sustainability consultant, the LCA practitioner would always be considered a design team member.  The exception might be if the practitioner is given only designs to assess by the active team members (architects engineers etc).  They will not be able to propose options but the design team may put forward suggestions for them to then test.  This is somewhat grey and could get challenging for the Bre to assess.  At eTool we have a large public library of recommendations for our users to review and test on their models. Would the practitioner who presents the model and recommendation options still be a 3rd party?  A far more appropriate and simplified approach would be to require a 3rd party verification whoever completes the LCA work, “3rd party” or not.

 

LCA Scope

The scope of the LCA is not entirely clear from the credit, should trade staff, their transport and equipment impacts be included?  eTool and our users always complete as full an LCA as possible to ensure there are no missed opportunities for improving the design.  We include trade staff and all equipment that they use to build and maintain the development over its life cycle (cranes, pile drivers, concrete pumps, vacuum cleaners etc). This can be of particular interest when, understanding different foundation systems and excavation requirements or when looking at modular buildings.

The scope of the LCA neglects finishes and fittings despite them making up a very significant portion of a buildings impacts. The current approach in the industry (and EN15978) is to include these and to assume the same products will be replaced throughout the buildings life cycle. We feel this is still the most appropriate approach and places emphasis on the elements that have the largest likely impacts under today’s conditions.  Taking LCA categories in their isolation can cause perverse design outcomes particularly in cases when the scope of the build also includes fit-out.  In whole building projects, the design team should be assessing each strategy on its environmental merits and prioritising.  Reducing the scope of the LCA only serves to reduce the scope for improvement strategies.  We recommend that when included within the scope of the build all optioneering should be included and given credit for, the LCA assessor will most likely do this anyway as a client requirement.

 

Functionality

eTool would also like to see some mention of “Functionality” in the principles.  Whilst there are challenges in benchmarking functionality good design is not being recognised in the principles and/or credit without some notion of function.  If an office can increase its floor plan by reducing service or car park spaces this should be encouraged (greater office area provided using the same resources).  Likewise, 60-year life expectancy is not accurate for the majority of high rise building which will be standing far longer and are therefore a more efficient use of resources and carbon than low-density buildings which will face more re-development pressure over their life cycle. Often much bigger environmental wins can be gained through improved functionality.  Consider a concrete low rise building in an urban centre, it may well be knocked down within 50 years.  A high rise on the same spot, on the other hand, may well still be standing in 100+ years this represents a 50% saving of impacts (in terms of kg CO2e/m2/year). eTool recommend that optioneering can include functional improvements and that an accurate life expectancy is considered when comparing options.

 

Negligible Items

Negligible items. Whilst nails tend to be pretty negligible, adhesive and certain brackets are not always, of course, this all depends on the scope of the LCA, nails could be the largest impacts of a small timber shed!  In a full LCA a great deal of adhesive can be used in carpets and finishes.  This is simple to quantify, xm2 times thickness (0.5mm of adhesive).  Likewise, brackets in curtain walling and other systems can be very significant.  It is rare that a design team member will know the area of glue on a particular component.  We would advise therefore that it is always included as a conservative assumption. If its looking like a significant item then more information should be sought and the model refined. The LCA assessor should always use their own experience to determine the negligible items and follow the EN15978 rule of 1% of total environmental relevance or the RICS guidelines of 1% of cost.

 

Super Credit

We think there is an excellent opportunity to go further by completing a full LCA/LCC including operational energy and water. This could in the future lead to the super credit whereby all chapters in Breeam that can be quantified through LCA – energy, water materials, pollution (perhaps even health) are assessed in a single model with each environmental strategy assessed based on its actual quantified merits.  This allows the design team the maximum flexibility in meeting their targets as well as delivering quantified results in terms of reductions of CO2e (or any other environmental indicator).

eTool believe that the current separation of energy, water and materials is no longer necessary with the advancements in standards, LCI data sources, LCA tools, and knowledge within the industry.  Siloed thinking of environmental performance in this way leads to adverse trade-offs for the planet.  The only way to prevent these adverse trade-offs is to use life cycle assessment within a life cycle design process.  The construction industry is recognising this and moving to LCA for environment decisions makings.  Examples below:

– In standards development: CEN was directed by the EU to produce standards for voluntary rating of sustainable buildings.  They developed “EN 15978: Sustainability of Construction Works, Assessment of Environmental Performance of Buildings, Calculation Method” which is entirely LCA based.

– In regulation: Laws such as the 2011 French Grenelle regulation require mandatory LCA-based environmental product labelling.

– In Green Building Rating Schemes: DGNB, the majority of the environmental points are achieved through an LCA (quantifying water, energy, materials holistically through their life cycle metrics.

What Cladding – a look at life cycle impacts.

Facade impacts can really add up, the cladding in particular on walls can take a real hammering in British weather and could be replaced 2 or 3 times over a buildings life cycle.  Picking the cladding with the lowest impacts can present significant savings both initially at product stage and over the life cycle as that cladding gets replaced.

I dropped a few of the cladding options available under Bre IMPACT to understand the heiarchy of choices that might present low carbon alternatives to design specifications

Capture

Of course their are many other factors that should be taken into account – framing, structure, glazing propotion etc but as a basic reference I thought the above might be useful.

Redução do Impacto do Ciclo de Vida do Edifício – LEED (Portuguese)

Análise de Ciclo de Vida (ACV) é uma metodologia usada para avaliar os impactos ambientais associados a todas as etapas da vida de um produto ou serviço. É uma abordagem holística que engloba a extração dos materiais, processamento, fabricação, distribuição, uso, reparo, manutenção, descarte e reciclagem ao fim da vida útil. A ACV quantifica os impactos ambientais e compara a performance por meio da funcionalidade do produto ou serviço. A performance de um prédio comercial, por exemplo, pode ser avaliada por meio do impacto ambiental por m2 de área locável por ano (kgCO2/m2/ano). O estudo de ACV permite identificar as potenciais áreas para aumento de performance e redução de impacto ambiental, podendo também incluir recomendações de melhoria para a equipe de projeto. A ACV é regulada pelo padrão internacional ISO 14044 (e EN15978 especificamente para edificações) e a aplicação na área de construção civil é utilizada mundialmente para promover desenvolvimento sustentável.

Na certificação LEED, o objetivo do crédito Redução do Impacto do Ciclo de Vida do Edifício é otimizar o desempenho ambiental de produtos e materiais e permite obtenção de até três pontos. Apesar da metodologia permitir avaliar impactos relacionados a todo o ciclo de vida do projeto, este crédito LEED (opção 4) tem o foco apenas na estrutura e recinto do edifício, durante período de 60 anos. Ao comparar a performance do projeto proposto com o modelo de referência (Baseline), a equipe de projeto deve demonstrar redução de impacto de no mínimo 10% em pelo menos três categorias de impacto (por exemplo: aquecimento global, depleção da camada de ozônio e eutrofização).

A eTool, empresa Australiana especializada em avaliação do ciclo de vida de todo o edifício, desenvolveu o software eToolLCD que atende aos requisitos técnicos da norma ISO 14044 e pode ser utilizado na certificação LEED. A eTool iniciou operações em 2012, já completou mais de 300 análises internacionalmente e é pioneira no uso de ACV para certificação na Austrália (Green Star). Atualmente, está expandindo os serviços na Europa (BREEAM) e nas Américas. Os projetos LEED que utilizaram o software eToolLCD incluem: King Square 2 – Cundall (Austrália), Wildcat Building – Arup (Dinamarca) e ENOC Tower – AESG (Dubai).

“A única forma de garantir redução de impacto ambiental é quantificar a performance ao longo da vida útil do projeto e a metodologia de ACV foi desenvolvida para auxiliar na tomada de decisões. Este crédito LEED será muito importante para as equipes de projeto trabalharem de forma ainda mais integrada e o software eToolLCD facilita muito esta análise”, afirma Henrique Mendonça, engenheiro da eTool que está de volta ao Brasil depois de passar cinco anos na Austrália e se especializar na prática de ACV de toda a edificação.

LCA – More than just Breeam credits

Since being awarded IMPACT compliance in Christmas 2015 eTool now have many clients successfully using eTool on either a consulting basis or as LCA software providers.  With an IMPACT compliant LCA they can guarantee the two bonus LCA Materials credits in Breeam New Construction 2011/2014. These credits are awarded as a bonus to the Green Guide materials credits and awarded for completing an LCA and reporting on the results. 6+1 credits can also be achieved under Breeam Fit-out/Refurbishment/International, up to 23 credits in HQM and 3 under LEED.  Upcoming updates to Breeam 2018 will award up to 10 credits.  The LCA modelling can also be used for life cycle costing Man 2 credits, and Mat 06 Resource Efficiency.  The Bre are trying to encourage uptake in LCA and for the time being the credits can be applied at any stage of the design – effectively points for trying.

But! There is a lot more to LCA than just some easy credits.  We prefer the term Life Cycle Design (LCD) to describe the powerful methodology that utilises Life Cycle Assessment (LCA) to model full environmental and cost impacts from cradle-to-cradle. Only when a complete picture of a buildings environmental performance over its life cycle is established  we truly know if we are making good design decisions. Benefits of incorporating an LCA approach into you project include:

  • Performance-based approach.  Which has the smaller impact, the nylon carpets shipped from overseas or the wool carpets locally sourced.  Only through quantifying the full impacts in terms of kgCO2e (or any other environmental indicator) can we truly understand.
  • Value engineering. The life cycle model will provide a plethora of design options for improving both the environmental and the cost performance of your asset ranging from zero to high capital cost. Only through quantifying the actual increases/reductions in CO2 and £ can the team prioirtise how to get the best value  from their design – achieving the greatest environmental gain for the smallest capital spend.
  • Innovation. LCA is growing in popularity as the most robust methodology for assessing buildings true environmental performance and represents the next level in sustainability reporting.
  • Approvals.  Certain councils are now giving credit to an LCA approach, sometimes in lieu of targeting costly and inappropriate energy targets (Barnet Council for example). LCA and embodied carbon are also regarded highly within the new London Plan.
  • Infrastructure. Within infrastructure there is a government mandate for HS2 to complete LCA analysis.  LCA also forms a very large part of the PAS2080 standard.

“A clear understanding of absolute impacts at aggregate and detail level is essential for identifying hotspots and exploring the real benefits of improvement opportunities. I highly recommend integrating eTool at earliest project stages to support systems thinking and inform decisions.” Patrick Jeannerat, Colliers International”

Below are just some of the clients who we have been working on LCAs with to date.  Although the primary motivation is often Breeam related, LCA is also providing some fantastic learning outcomes for design teams.

“We have been using eToolLCD for the last year and have completed 3 certified assessments.  This has enabled us to give our clients and design teams valuable information on the environmental impacts of design options as well as giving an additional 2% to the projects BREEAM assessment once the eToolLCD model has been certified.” David Barnes, Volker Fitzpatrick 

Aligned with international standards for LCA, Life Cycle Design is guarenteed to enhance the sustainability of your project regardless of your role, the type of project or what stage it’s at. Find out more about our recent projects here.
