100X faster engine

We are thrilled to announce the release of Sefaira Concept v1.4.0, which has some truly amazing new features, including a rebuilt engine that is up to 100x faster.

Faster Engine

Our upgraded engine analyzes models up to 100x faster than before. That means you can perform even more investigations, analyze more complex models, and get great data faster than ever before.

Improved Rainfall Data

We’ve updated rainfall data for over 1,000 locations worldwide, and will continue to improve our data in the future. For existing projects, the new rainfall data is automatically used the first time you re-run your analysis. New projects will use the new data by default.

Bug Fixes

As usual, we fixed a few bugs.

Site maps: Fixed a bug in which project map images occasionally fail to load.
Water strategies: Fixed a minor problem with certain combinations of water-related strategies that caused the app to become unresponsive.
Create Concept from strategy: Fixed a bug involving the creation of a new Concept from a strategy or bundle. Now when you create a Concept from a bundle or strategy that contains variables from a toggleable group, that group is turned “on” by default in the created Concept.
Site Area units: Fixed a minor bug in which the units for Site Area occasionally failed to load.

As always, Sefaira’s engineers are here to help you with all your sustainable design projects. Should you have any questions, comments, or ideas, please let us know!
