Changes 27 Feb 2024

A new cost component “Carbon emissions tax” is available for the Pareto Analysis
The Admin Portal is undergoing changes to improve support for user bound licenses, like the BIM Syncer.
- As such the User edit screens are extended with a License Assignments section.
- This will enable assignment of licenses to individual users, potentially differentiating which features are available to which users.
- This is a preparation step. There is no enforcement YET of the selections made here. This will come in an upcoming release.
  - Hence, no changes are required and license assignment will be handled automatically
  - Expect the BIM Syncer license assignment to be integrated into this screen in an upcoming release.
New "Polyvalent four-pipe heat pump" base circuit has been added to both the heating and cooling libraries. The polyvalent four-pipe heat pump is a heat-pump based production unit that can deliver simultaneous heating and cooling, independent heating and independent cooling all in one system.

- The launched date-time of the activity.
- The user who launched this activity.
- The current activity status.

Filtering of activities can also be done in this view, the filtering can be done on the basis of

- Current status of the activity
- Activities started between a particular time period
- Activities launched by a particular user

Changes 26 Sep 2023

Some models created between 12 Sep 2023 and 26 Sep 2023 , might have a deprecated diversity standard (based on DIN1988-300 v1) defined by default.
If that's the case for your model, the diversity standard will be automatically upgraded to the newer version (based on DIN1988-300 v2) when you open it again. This might influence (improve) your diversity calculations a bit.
Simulation results are no longer lost on any save. They are retained until a change is made that could potentially influence the results.
- E.g. Adding labels, moving BCs, ... should no longer lead to loss of simulation results
- E.g. Changing a parameter, pipe length, model settings... will still lead to loss of simulation results on save as they constitute changes that will affect simulation results.
Introduction of multiple x-axes in graphs: we display multiple x-axes for the use cases where different series with different x-axis units get shown together.
Showing general simulation details in the sensitivity status page, i.e., start date, duration, weather profile are now visible in the sensitivity status page.
