Release Notes

by: Phil Northcott, C Change Labs.

We make regular updates to the EC3 tool based on your feedback.  Here are a few of the most prominent that we would like to share with you. 

Calculator for Insulation  

Insulation products are declared in a slightly counterintuitive way, in multiples of 1 m2 with an RSI of 1.   In EC3, when you specify an Insulation, a calculator will appear to help calculate the right quantity from the desired R-Value and area.  Supports both USA and SI units. 

 

Sample Bid Documents and Supplier EPD Request Letters  

A set of sample bid documents and supplier letters are now provided in the Building Planner, courtesy of Skanska USA.

View BIM import results in 3D

We are constantly working on improving BIM imports, but not every BIM element is going to translate successfully.  The latest feature allows you to view which parts of your model imported successfully in 3D, using the Large Model Viewer.  Clicking on the element brings up an explanation of the issue.

Extra-large BIM models

Some BIM models have hundreds or thousands of BIM types, too many to map reasonably.  We have implemented new features to summarize these, such as in this example of a French building.

Tree Diagram, LEED chart, or Sankey?

You can view GHG impacts as a Sankey Diagram, Tree Diagram or a LEED-customized bar chart from the Building List.

Better Product comparisons

When comparing products, you can now interactively select any of the products in the list and see comparisons in real time.  Just click on "Compare Materials" to get started.

Easier EPD imports to EC3

The "Import EPDs" function now provides substantially more information about the status of an EPD you are trying to import, and explains what each status means.

Search multiple manufacturers/plants

When searching for EPDs, you can now select several specific manufacturers or plants sumultaneously, not just one. 

Bug fixes and more data!

Many, including fixes to the LEED charts, resilient flooring, the Operating vs. Embodied graphs, and Manufacturer editing functions.

We love to hear your comments and feedback.  Most of the above features came in response to specific feedback from users (you know who you are!).  Please make use of the Report Bugs and Feedback  tool to let us know what you think. 

 

Thanks as always to the forward-thinking organizations who sponsor BuildingTransparency, and our intrepid Pilot Users who help us shape and improve the tool.  Amid the pandemic and rampant injustice, let's be calm, be safe, and be kind. 

 

Filter EPDs by specific PCR

You can now search and filter EPDs to find ones that use the same Product Category Rules.  The search box will show all PCRs that apply to the category or its parent.

Users now displayed by name and employer only

As part of our ongoing improvements in privacy and confidentiality, professional users now show up by name and employer, rather by your email address. As before, Private users will not be visible, and cannot use the sharing functions.   To become a Professional user, you just need to enter your employer and profession, demonstrating that you have entered business contact information (rather than personal information).

Adding new EPDs to EC3
Adding EPDs to EC3 is now easier using the Import EPDs function in the left sidebar.  EPDs you have uploaded will be shown with their current import status.  Old methods such as emailing PDFs to epd-uploads@building transparency.org, direct API imports, and uploads via box.com remain available.   

Exclude products with certain options.

You can now click an option a second time to search while excluding materials with a certain optional feature.  Currently this feature only works with a few materials, but it will be enabled for the remaining materials over the next month.

Templates for Commercial Buildings in SI and USA units

There are now Templates for commercial buildings, containing examples of most of the major materials, along with notes and suggested calculations.   Save As Copy to get an editable version of your own.

Preview EPD before uploading
When you upload an EPD, you can use 'preview' to check the file you're uploading.  This also helps answer a couple of questions we ask you that help us parse the document (the material category and Program Operator).  If you don't know the answers, you can leave them blank.  

CSV download with selected materials

The CSV download of the building project now includes total realized impacts based on the selected materials.
 

Bug fixes and missing data
Many, including data for selected materials in the CSV download, support for more BIM360 features, and a bunch of fixes to the LEED charts.

Please make use of the Report Bugs and Feedback  tool to share your ideas and bug reports.  C Change Labs is grateful to forward-thinking organizations who sponsor BuildingTransparency, and our intrepid Pilot Users who help us shape and improve the tool, who together allow us to deploy cloud technology in the fight to preserve our climate.  

Embodied Carbon vs. Operating Carbon

Compare embodied vs. operating carbon impacts based on the Conservative estimate for the building, the EUI, local grid, and local gas supply.  The graph incorporates anticipated decarbonization of the grid between current levels and 2050.

Elements made up of multiple layers

For walls, decks, and other building elements with multiple layers, you can now create multiple materials, using simple math to create stud spacings, layer thicknesses, and so on.  The quantities are multiplied up for you in Masterformat view and Sankey diagrams.

BIM Imports in the Background

When you import a building from BIM360, you can now let EC3 do its work in the background, while you do other work (including importing other buildings).  EC3 will notify you when it’s done, with a report of what occurred.

Improved LEED Charts

The Selected vs. Baseline chart is now much improved based on user feedback, with clearer data notations and several bug fixes.

Bug fixes and missing data
Many, including LEED charts not showing for non-Pilot users, inabilty to copy buildings, and a major infusion of new insulation EPDs.

Selected vs Baseline Chart

The new Selected vs Baseline Chart compares the selected material(s) for the builiding against the CLF conservative baseline and the EC3 achievable target, for eight material types:  concrete, steel, wood, Aluminium, Glazing, Insulation, Ceiling Panels, and Carpet.

3D view of how Selected Material stacks up in Large Model Viewer

BIM360 imports are now colorable by relative performance of your selected materials vs. the best available.  Use the dropdown control at top right and choose “Selected Material”.  The name of the selected material is also shown in the property view box.

Large BIM Imports
Users with large BIM models will now be able to import from BIM360.  To contain the number of materials that must be mapped, EC3 combines Revit families in the same model and using the same structural material into a single EC3 Building Element, in cases where there are large numbers of such families.

BIM360 en français

Nous avons amélioré EC3 pour mieux supporter RVTs françaises.

Better reports for non-English languages

Downloading BIM and Tally import reports, or the entire project as CSV now properly supports characters like é, ñ, and ü.  

Bug fixes and missing data
Many, including linking most Industry EPDs with the correct PCR, fixing overly-enthusiastic privacy protections, and more.

Easier Selected Material search

To make it easier to select a material, entries you make in the filter bar no longer change the statistics of your overall search, they only change the list of EPDs shown.

Manufacturers Edit Product Specs
Manufacturers who are signed up with EC3 can now review and edit the description, performance specs, and plants associated with each material.  However, only the Program Operator can edit environmental data.  Manufacturer reps wanting edit permission for their company should make a request via  Report Bugs & Feedback.

Downloadable Product Category Rules

Every EPD in EC3 is now has a link to its PCR document, which you can download from its publisher.

Sankey Diagram Improvements

  • Hovering over any path shows the Building Element it represents.
  • Clicking on any of the sub-assembly bars  zooms in to just that sub-assembly
  • Really big Sankeys now group the smallest elements into 'Other'. Zooming in will let you see more detail.

Building Project Search Bar

Convenient search bar for building projects.  Searches by name, user ID, keywords like "Tally" and "BIM", and more.

Tally Import Reports

Tally imports now show the % of Tally materials successfully imported.  You can further refine the results by adding performance specs and geographic info, if you know them.

Better Building Comparisons

More details and clearer explanations when you compare multiple options or multiple buildings.
