Changes to Green Star – D&AB v1.2, Interiors v1.2 and Communities v1.1

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.

eTool have completed and peer reviewed over 50 LCAs for Green Star projects and we have a great group of eToolLCD users that are constantly providing feedback to improve the way we quantify and improve project performance using Life Cycle Design.

In early July 2017, Green Star released the 1.2 version for Design and As Built and Interiors rating tools and the Materials Life Cycle Impacts credit was further improved, as follows:

  • Points may now be easier to achieve for some projects provided there’s early engagement of LCA consultants
  • Projects registered with Green Star after September 2017 will need to engage early. Projects that wait until very late in the design process to begin the LCA may be limited to 4 points of the available 7.
  • Points allocation have been adjusted with operational energy reductions capped.
  • Further Additional Reporting initiatives were added with extra points available.
  • Additional guidance throughout to improve clarity and other updates.

Design and As Built v1.2 points breakdown – Up to 7 points in total:

  • Up to 6 points for performance (limited to 3 points for operational energy improvement)
  • Up to one point for LCA Design Review (early stage)
  • Up to 1 point for material changes informed by the LCA
  • Up to 1 point for construction process change informed by the LCA
  • Up to 1 point for reporting additional indicators
  • Innovation: 1 additional point where the cumulative impact reduction as defined within the credit is increased by 20% to a total of 150%.

Interiors v1.2 points breakdown – Up to 19 points in total:

  • Up to 18 points for performance (limited to 12 points for operational energy improvement)
  • Up to 1 point for reporting additional indicators
  • Up to 2 points for material changes informed by the LCA
  • Up to 2 points for construction process change informed by the LCA
  • Up to 2 points for LCA Design Review (early stage)
  • Innovation: 1 additional point where the cumulative impact reduction as defined within the credit is increased by 20% to a total of 150%.

Communities v1.1 points breakdown – Up to 5 points in total:

  • Up to 4 points for performance (whole of site impact reduction)
  • Up to 1 point for reporting additional indicators

The Life Cycle Design process using eTool services will now be:

  • Target Setting Study conducted at Concept Design Stage
  • Life Cycle Design Services conducted later in the design project when energy modelling has been undertaken

Note to eToolLCD users: The Indicator verse Life Cycle Phase Summary report can be used for LCA Design Review. The Target Setting report will be updated soon to include multiple indicators.

eTool hosted a webinar to present the recent changes in Materials Life Cycle credit and how to maximise design value using LCA methodology.

Stay tuned for other updates and get in touch if you need further details.

eTool’s Thoughts

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 land owners 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, acidfication, 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 provide 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 Allignment: Aligning he 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 soffering. 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.

 

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 practiotioner 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?

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.

eTool Has A CEO

Announcement

We are very excited to see the advancements of Life Cycle Design applied to the construction industry, from consultants adopting the methodology at concept stage and use for regulatory purposes to Green Building rating system using LCA to form part of their scheme core structure, and many other applications. We envisage other opportunities as we continue to grow our presence in Australia and New Zealand. The European office is producing great results and we develop a new market in the Americas.

A few years ago at eTool we identified eToolLCD software as the main revenue driver in the coming years. Pursuing that outcome as well as our many other goals has led to the appointment of a CEO. Co-founders Alex Bruce and Richards Haynes decided that 2017 was the year to make the move and began their search for a CEO.

Of utmost importance was someone with the high ethical standards the rest of us have around here and, of course, a passion for saving the planet. The search led them to Matt Szwedzicki who is a friend and former colleague of both co-founders. He was originally approached to “sense check” the attractiveness off eTool as an investment and had some great positive feedback about the business.

Matt graduated from The University of Western Australia in 2000 with a Bachelor of Engineering (1st Class Honours) & Bachelor of Commerce. He has worked with some of the country’s biggest companies including Woodside Energy, Origin Energy and Elixir Petroleum where he was Chief Operating Officer. He is also Director of Southwesterley Group, an investment and fund management company.

We are excited to welcome Matt on board and are looking forward to him helping eTool become the mass carbon saving machine we all want it to be.

HBF Arena – Life Cycle Costing

eTool was engaged by EMCO to conduct a Life Cycle Costing (LCC) study on the HBF Arena Upgrades located in Joondalup – WA. The design development report required a conclusive whole facility life cycle cost analysis showing cost elements to be budgeted for in each year of the planned project useful economic life.

 

The object of the assessment was the structure itself. eToolLCD software was used to model the LCC using available construction drawings. The assessment included all the upstream and downstream processes needed to provide the primary function of the structure from construction, maintenance, operation, and finally demolition and disposal. The inventory included the extraction of raw materials or energy and the release of substances back to the environment or to the point where inventory items exit the system boundary either during or at the end of the project life cycle.

LCC Diagram

LCC Diagram

The results of the life cycle model over the 50 year period showed little difference between the benchmark design and the concept design as both assume NCC compliant ‘deemed to satisfy’ thermal comfort measures. It was assumed that the concept design had slightly better energy consumption due to design features (like the extended roof) which should be of benefit. These design features were also reflected in the capital costs of the building design. The Low Impact design (assuming all low impact strategies are put in place) significantly exceeds the performance of the other designs modelled. This is due to energy cost savings which are significant (over $100,000) in the first year and expanding over time with inflation).

Opportunities – The study highlights a number of opportunities to improve the LCC of the buildings during the operational phase. These are summarised below:
• Care for the sprung floor in the sports hall to extend the life past 25 years.
• Care for other floor finishes (carpet and vinyl throughout) to extend their life.
• Care for the sports seating in the sports hall to extend life past 15 years.
• Ensuring energy is conserved by switching off lights and air conditioning in zones that are not in use.
• Ensuring building ventilation systems are deactivated when the buildings (or zones) are not in use.
• Minimise cleaning costs by spacing cleaning frequency, careful selection of service provider and setting high expectations of occupants regarding cleanliness.

eTool LCC is a whole of building, whole of life design approach aimed at improving the economic performance of buildings. The scope of the LCC model provides certainty that design decisions made with the aim of improving performance of one life cycle stage or component of a building don’t result on poor trade offs and net reductions in performance.

ACV de Edificação – Mais fácil e perto de você (Portuguese)

Quantificar sustentabilidade ambiental foi o desafio que deu origem à empresa eTool. Desde 2010, os amigos e engenheiros australianos Richard e Alex desenvolvem o software eToolLCD para realizar cálculo de impacto ambiental na construção e promovem uso da metodologia Avaliação de Ciclo de Vida (ACV) para garantir performance ambiental genuína nos projetos em que participam.

Desde então, a equipe da eTool cresceu e expandiu da Austrália para a Europa e agora também para as Américas. A empresa já completou mais de 200 análises de projetos residenciais, comerciais e de infraestrutura, prestando serviço de consultoria ou fornecendo solução de software para a equipe de projeto.

O software eToolLCD é totalmente web-based, atende às normas ISO 14044 e EN15978 (específica para ACV de edificação), possui atualmente mais de 1.500 usuários ao redor do mundo e pode ser utilizado para obter pontos na certificação Green Star, BREEAM, LEED, entre outras.

Eu trabalho com a eTool desde 2012, onde me especializei em Avaliação de Ciclo de Vida e fui líder da equipe responsável por conduzir os estudos técnicos e colaborar com a equipe de desenvolvimento de software. Depois de morar cinco anos na Austrália, voltei para o Brasil para dar continuidade ao trabalho que iniciei em 2014, mas agora em definitivo para desenvolver a eTool Américas. É um grande desafio e também uma realização pessoal e profissional trazer para o Brasil uma metodologia que ainda não é muito utilizada, mas tem um grande potencial para auxiliar equipes de projeto a reduzir o impacto ambiental das construções e também demonstrar viabilidade financeira por meio da Análise de Custo do Ciclo de Vida.

Somos uma empresa apaixonada em projetar melhor e garantir bem estar social e harmonia com o meio ambiente. Estou entusiasmado para trabalharmos juntos.

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.
