I just wanted to make an announcement that is only for people staying up-to-date with the latest development version of the LBT Plugin using the LB Versioner component. So this does not concern anyone using the last stable release of the LBT plugin (version 1.4.0 directly from Food4Rhino).
We just finished upgrading the development version of the LBT plugin to use OpenStudio 3.4 instead of OpenStudio 3.3. We have updated the compatibility matrix accordingly.
There were relatively few breaking changes between OpenStudio 3.3 and 3.4. Furthermore, thanks to the efforts of the developers of EnergyPlus and OpenStduio, there are several important new features and bug fixes that we will benefit from in the Ladybug Tools community. To list a few major ones:
- It is now possible to import schedules and loads from the IDF format given that Tim Coleman added a means of importing the Schedule:Year format used in IDFs to the ScheduleRuleset format commonly used in OpenStudio and Honeybee.
- The various display_names of Honeybee Rooms are now translated to gbXM thanks to this issue that was addressed in the OpenStudio SDK.
- A previous EnergyPlus bug in the auto-calculation of water mains temperature from EPW has been fixed, meaning that service hot water load calculations will be a little more accurate going forward.
- Certain large models with many rooms connected by AirBounadries are now simulate-able in EnergyPlus thanks to this bug fix here.
In case it’s helpful, the last development version that works with OpenStudio 3.3 is LBT
1.4.79. So you can always plug
1.4.70 into the
version_ input of the LB Versioner component to get the last LBT version that’s OS 3.4-compatible.
