Technical Director’s 2025 Highlights and Look Ahead

Technical Director’s 2025 Highlights and Look Ahead
December 18, 2025

Friends and colleagues,

I hope you’re winding down for some well-deserved holiday time with family and friends. I wanted to thank you for your support through a challenging year for Building Transparency, and share what we accomplished and where we’re heading.

What we delivered in 2025

Early this year, we deployed our latest EPD Parser using AI models to improve digitization. Your uploaded PDFs are now processed with Claude’s help, and we continue refining our algorithms and prompts to improve data quality and comprehensiveness. Of course, AI is just one part of the equation—it still takes our dedicated team to manage the complex world of EPDs, PCRs, and LCA standards.

EC3 grew by over 12,000 EPDs this year, now covering more than 200,000 EPDs representing products from 67 countries.

Tally updates

Many of you have been waiting for Tally 2.0, which has unfortunately been delayed; however, work on Tally 2.0 continues, and we’ll share updated timelines in the coming months. In the meantime, in June, we released our annual update for Revit 2025 and 2026 compatibility and refreshed core Industry EPD data for the current version of TallyLCA.

Security and infrastructure

In the latter half of the year, we made significant backend improvements to EC3—enhancing our development processes and investing in new security and monitoring services. This work culminated in successfully completing our first SOC 2 Type 2 audit, receiving our report in October. You can see more about our security posture in our Trust Center.

This is critical for the 2,000+ organizations across 84 countries now using the EC3 Project Planner to track embodied carbon on building and infrastructure projects.

The team

One of the most exciting developments has been re-growing our small but mighty team, thanks largely to our Board’s dedication.

Looking ahead to EC3 2.0

I’m energized about 2026, when we’ll modernize how Building Transparency’s tools deliver on our mission. We’re planning a comprehensive EC3 2.0 overhaul that includes:

  • Building next-generation, cloud-agnostic database architecture for better performance and reliability
  • Engaging with a multi-stakeholder group on improving our data schema and API, in turn improving interoperability with other platforms
  • Completely redesigning the Materials database UI/UX for speed, clarity, and better filtering and comparison tools
  • Enhancing Project Planner with ECHO Schema alignment, streamlined data entry, spreadsheet imports, and B4 + C1-C4 calculations for whole-life carbon
  • Exposing assembly builders via API for seamless third-party integration
  • and much more…

We’ll be engaging with stakeholders throughout the process to shape these improvements. If you already engage with us via the in-tool feedback button, we have your feedback, but we also welcome additional feedback via this form. More details on further stakeholder engagement to come early next year.

I’m grateful for how dedicated every member of BT’s team has been since our start in 2020, and I’m excited to continue this work toward a better, low-carbon future for many years to come.

Happy Holidays,

Vaclav Hasik
