Green Building Calculator – bespoke

Not Bespoke but options:

  • GBC Green Building Calculator is available as XLSX format file
  • If you need XLS please contact GBC
  • If you need other file formats please contact GBC

Bespoke versions can be made including: 

  • Corporate Identity, layouts and logos
    • Carried out by GBC for users
    • Maintaining calculator integrity

Bespoke Modules can be developed:

Historic Building Window Intervention Calculator

  • At STBA and SPAB 2020 Conference GBC suggested a bespoke module to compare window improvement cost and carbon analysis

This was developed as a mock up of a spreadsheet by brainstorming the possible solutions and placing a gut-instinct value in the cells.

  • The plan would be to replace the + and – with calculated numbers

  • This has been recreated in GBC awaiting future development
  • Retrofit Bespoke datasets will be collected from bespoke research publications and added
  • The Event organiser has commissioned the development of the Historic Fabric Bespoke Calculator
  • This bespoke development is underway with the support of Historic Environment Scotland

Infrastructure Calculator

  • A recent GBC CPD for Women in Sustainable Rail and CIOB was an opportunity to talk about Infrastructure Embodied Carbon, PAS 2080, ICE V3, CEEQUAL and Carbon counting of materials and transport of heavy materials, etc.
  • Inevitably showing Green Building Calculator will reveal the early Infrastructure components waiting to be developed in a later version.
  • GBC will show how users can do their own calculations, get ahead of the curve or help GBC bring this module forward for early completion.

Peer-Previewed LCA and EPD generator?

  • In the event that a manufacturer has one primary ingredient that gets mixed to a number of products recipes with subtle performance differences, mixed in many locations with locally specific ingredients.
  • The permutations would make doing an LCA and EPD for every mix time consuming (a problem for this product group) and costly.
  • I wonder if there is a possibility to develop a method of generating LCA and EPD in a semi-automatic way that can be Peer-Previewed as a system to generate EPD rather than a Peer Reviewed EPD?
  • I could envisage a MS Excel template spreadsheet including look up tables of readymade recipes, readymade ingredients, ready made travel distances; and drop down lists corresponding to the look up table items.
  • Then the manufacturer could open MS Excel Template to create a new LCA/EPD file and then choose the recipe specifics from the drop down menus, which auto-populate the LCA spreadsheet cells and auto-carryout the LCA calculation and auto-feed it into a MS Excel Template EPD?
  • The pieces of information needed would be the recipe and location specific, the choice of local ingredients and the unique recipe specification.
  • The output would have the advantage of being a Peer-Previewed EPD and could be issued almost immediately after the specification and sent with the specification to the customers, mixing plant and site.

Challenge the LCA EPD Status Quo

  • I suspect this would be unique and may challenge the LCA EPD world and they may even want to object to its development, or object to its Peer-Previewing in principle.
  • I could imagine this being useful in many walks of life
  • I think we need to challenge the status quo and see if this can be done.
  • It will make a very interesting Case Study and may push the boundaries of what is permissible in the LCA and EPD arena.
  • It may require some BS EN ISO standards to be updated.
  • It will probably be a useful marketing platform to get some mileage out of for all parties.

Developer Version

  • An unlocked version for user development can be available under an NDA.
  • There will be no hidden pages: all cells will be accessible to interrogate the calculations
  • It allows users to customise, manipulate and develop unique versions for their organisation
  • With GBE guidance in order to maintain calculator integrity
  • GBE will encourage user developers to share there unique parts for consideration for the core product
  • GBE will establish and maintain a stakeholder group to steer the development of GBC
  • A BIM App is on our agenda at Version 15 unless users want it sooner
    • We will have conversations early to avoid end of cul-de-sac issues

International Version

If the world is watching and would like to join in:

  • £ conversion to Euro or other currencies
    • Regrettably we left EU (sort of, almost entirely),
  • Metric to Imperial
    • USA is asking for feet and inches, etc.
    • We asked USA to find somebody to do the conversion for us
  • U (UK) and R (EU) values
    • Both already exist in ‘Elements’
  • Local/Regional/National/Europe/International ‘Product’ datasets
    • A worksheet is available to submit other products, accessories and systems to enhance GBC
    • Free upgrade to current or next version as a reward
  • National Regulations or Local Green Building Council Targets
    • A worksheet is available to submit other regulations or standards to enhance GBC
    • Free upgrade to current or next version as a reward
  • Regional LCA Datasets
    • A worksheet will be available to submit other LCA datasets to enhance GBC
    • Free upgrade to current or next version as a reward
