TEASER - v1.0.1

Major release with breaking changes

This new TEASER release fixes many bugs and adds several features, mainly new buildings constructed after 2015 based on the KfW standard. This new feature required to change the current archetype parameterization based on usage, methdo, and construction_type to geometry_data and construction_data:

  • Geometry data is just method and usage, e.g. geometry_data = f"{method}_{usage}".
  • Construction data is basically the old method associated with a retrofit state, e.g. tabula_de_standard or iwu_heavy. The previous construction_type heavy oder tabula_standard only worked with iwu and tabula_de anyway.
    See more here: * Issue745 add kfw archetypes by @jonas0902 in https://github.com/RWTH-EBC/TEASER/pull/757

Also, we now only use the main branch. To update locally:

git branch -m master main
git fetch origin
git branch -u origin/main main
git remote set-head origin -a

TEASER - TEASER release v0.7.0

Pre-release status

We want to state, that this release is a pre release and so a (maybe) non stable version with bugs. It is not that havily tested as the other releases. As the enhancements are great we have nevertheless decided to publish this release. So apologies for that.

Non-backwards compatibility

We no longer support python 2.7!

A lot of functions have been deleted in this release (e. g. all XML and GML interactions and old Project() functions for generating archetypes. We highly recommend to use this version.

New classes, parameters and name changes

We deleted the package module boundaryconditions all parameters moved to the class UseConditions. In particular if you changed the use conditions settings manually you will experience a lot of changes, among these are renamed parameters and additional parameters.


# Parameters for heating or cooling
with_heating: boolean
    Sets if the zone is heated by ideal heater or not.
with_cooling: boolean
    Sets if the zone is cooloed by ideal cooler or not.
with_ideal_thresholds: boolean
    Sets if the threshold temperatures for ideal heater and cooler should
    be used to prevent simultaneous heating from AHU and cooling from
    ideal heater and vice versa. This should only be turned on if an AHU
    exists.
T_threshold_heating: float [K]
   Threshold temperature below ideal heater is used. Default is 15 °C
   which corresponds to the value for all buildings that are not built
   according to EnEV standard according to DIN EN 18599-5.
T_threshold_cooling: float [K]
    Threshold temperature above ideal cooler is used. Default is 22 °C ,
    since there are no european standards for cooling degree days this value
    is taken from the following paper: "Heating Degree Days, Cooling
    Degree Days and Precipitation in Europe—analysis for the
    CELECT-project" by Benestad, 2008.
heating_profile : list [K]
    Heating setpoint for a day or similar. You can set a list of any
    length, TEASER will multiplicate this list for one whole year.

    Annex: Used for internal gains
persons_profile : list
    Relative presence of persons 0-1 (e.g. 0.5 means that 50% of the total

TEASER - TEASER Release v0.5.0

This is release v0.5.0

Before using this release you will need to update PyXB to version 1.2.5 to do so use python-enabled command line:

pip install -U pyxb

This is a major release cleaning up the calculation for AixLib and modelica IBPSA (former Annex60) models. After there have been major developments in these models, we had the feeling that TEASERs calculation needed some restructering as well. The parameter calculation for different models (one, two, three or four element) is now encapsulated in specific classes and attached as an attribute to each thermal zone. Library specific calculation for buildings is as well moved to specific classes. All mentionend modules are within the package logic.buildingobjects.calculation.

From this relase on, we do not support all modeling options for AixLib any more, as we had the feeling that they where not used anyway. The only available option for AixLib is a MultiZone model where the number of elements of the zones may be chosen as well as the centralized air handling unit. It will always decouple the resistance for windows, calculate a correction for solar gains of the window and uses internal gains calculation of AixLib. For IBPSA (former Annex 60) model it is still possible to set model options. If you compare old simulation results, please be aware that with this version the night set back for AixLib is by default true (while it was false in other versions). To turn off the night set back please have a look at the module logic.buildingobjects.calculation.aixlib. In addition we revised solar absorption for all used materials, which may also cause differences in the results.

We also changed API functions for archetype generation, please read the docs and look out for warnings if old API functions are used (the old functions will still work, but will be eleminated within the next releases). Further, examples and documentation have been improved.

If you have any questions regarding this release, please contact us at [email protected].

Improvements in this release:

  • continuous integration for Python 2.7, 3.4, 3.5
  • restructured and modular calculation for model and library parameters
  • revised values for solar absorption for materials
  • night set back is always turned on
  • new examples
  • new API functions
  • improved documention

TEASER - TEASER Release v0.3.0 going open source

With this release we introduced a lot of non-backwards compatible changes, thus we highly recommend you to check your scripts using TEASER. There are probably two things you need to do:

  1. all modules and packages are renamed to lower case (e.g. change import teaser.Project to teaser.project) to be PEP8 conform
  2. If calculating simulation parameters, we do not longer support the parameter calculation method. If you want to use vdiplease set the following parameters:
project.used_library_calc = 'AixLib'
project.number_of_elements_calc = 2
project.merge_windows_calc = True

If you want to use ebc

project.used_library_calc = 'AixLib'
project.number_of_elements_calc = 2
project.merge_windows_calc = False

Further features of this new release:

  • beta release of the gui (it is not pretty, yet only works for AixLib and probably has some bugs, BUT it is a beginning :-) ) If you find any bugs or problems with the gui, please report them to us!
  • import of CityGML files
  • support of Annex60 model calculation
  • lot of smaller features and bugfixes

Hard facts: more than 600 commits and about 80 closed issues.

Please keep in mind, that this is still a pre-release. We are still working on the code and try to maintain it as good as possible. If you find any bugs or run into any problems using TEASER, please report this to us!
