Green Building Calculator – bespoke

Options

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

Your options

Bespoke versions can be made including: 

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

Bespoke Versions

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 Options Appraisal

  • STBA has commissioned the development of the Historic Fabric Bespoke Calculator
  • This bespoke development is underway with the support of Historic Environment Scotland
  • GBC and STBA presented it in the Retrofit Arena at Futurebuild 2022
  • It includes a Survey worksheet, for dimensional information and descriptive data
  • There are cells with drop down lists to choose from to control the cell content to ensure results
  • Retrofit Bespoke datasets have been collected from bespoke research publications and added
  • Building types from English and scottish housing conditions surveys and created as look-up tables
  • Risk factors have been developed by STBA and included as part of the reporting to users function
  • It will be developed as an on-line tool on an STBA website

GBC Retrofit

  • GBC has reserved Stand F9 at Regen 2nd-3rd November 2022 St George’s Hall Liverpool
  • We plan to show new Retrofit features within GBC V2 or later additions

Infrastructure Calculator Module

  • A recent GBC CPD for Women in Sustainable Rail, CIOB and a University lecture were opportunities 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 reveals the early Infrastructure components waiting to be developed and implemented in a later version.
  • GBC shows how users can do their own calculations, get ahead of the curve or help GBC bring this module forward for early completion.
  • See GBC CPD Carbon Counting Calculators (CPD) (Event)
  • GBC CPD Seminar C#983
  • GBC at University Learning C#964

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 Versions

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
