As in previous versions, the release comes in two variants:

EINSTEIN_2.2-Installer.exe
a bundle installer for MS-Windows 7, Vista and XP that contains not only EINSTEIN but the MySQL server, a Python environment and all dependencies in one installer.
EINSTEIN_2.2.zip
is only EINSTEIN. If you’re comfortable with setting up the data base and providing the necessary Python environment by yourself, this variant offers the smallest download size. It is also the most sensible choice for users on a different computing platform than MS-Windows.

EINSTEIN 2.2 can be used as an update to existing Einstein installations of any version.

2.6. Version 2.1

(November 2011)

we are happy to announce the 2.1 release of EINSTEIN. This release is an intermediate result of ongoing work in the Framework of the project IEE-EINSTEIN-II. It contains stability improvements and improvements to existing features.

Since version 2.0 the following new features were introduced:

  • introduction of thermal chillers as an equipment type
  • a separate treatment of air handling in buildings
  • Bulgarian as a new language for the GUI and the report generation

Since version 2.0 the following improvements were made:

  • differentiation between indoor temperature and heating system temperature
  • differentiation between process temperature and minimum supply temperature to processes in general
  • a flow chart input for process and pipe parameters for an easier understanding of the meaning of the parameters.
  • the possibility to connect heat exchangers as a low temperature heat source to heat pumps.
  • improved consistency checks of process temperatures
  • a speed up of the heat pump simulation code
  • updates of the French translation
  • updated technical documentation
  • several improvements to the GUI
  • fixes for several crash bugs in the simulation code
  • and a lot of the usual small bug fixes

The release comes in two variants:

EINSTEIN_2.1-Installer.exe
a bundle installer for MS-Windows 7, Vista and XP that contains not only EINSTEIN but the MySQL server, a Python environment and all dependencies in one installer.
EINSTEIN_2.1.zip
is only EINSTEIN. If you’re comfortable with setting up the data base and providing the necessary Python environment by yourself, this variant offers the smallest download size. It is also the most sensible choice for users on a different computing platform than MS-Windows.

EINSTEIN 2.1 can be used as an update to existing Einstein installations of any version. An update from 2.1 prereleases is recommended.

2.7. Version 2.0

This major release contains several new fundamental features. This release is an intermediate result of ongoing work in the Framework of the projects IEE-EINSTEIN-II and EINSTEIN in Austria.

Since Version 1.2 the following major features have been introduced:

  • the integration of buildings as entities with energy demands
  • an new, detailed heat recovery model that is implemented in python replacing the old c# based “MS windows only” solution
  • processes with cooling demands and the corresponding equipment to generate cold
  • the possibility to model processes with multiple inflowing and outflowing media

And the following improvements were made:

  • French as a new language for the GUI and the report generation
  • a finer grained simulation of the covering of energy demands that takes the user defined connections between energy sources and sinks into account
  • higher stability by fixing GUI bugs that led to freezes of the whole application
  • a simple overview window to see the interconnections of equipments, pipes and processes
  • and a lot of the usual small bug fixes

2.8. Version 1.2

The 1.2 release of EINSTEIN is an intermediate result of ongoing work in the Framework of the projects IEE-EINSTEIN-II and EINSTEIN in Austria.

Since Version 1.1 the following major changes have been introduced:

  • the possibility to model complex time schedules in processes
  • an improved editor for EINSTEIN data bases
  • better plots in the graphical interface by integration of matplotlib
  • a graphical installer for MS-Windows XP, Vista and 7

2.9. Version 1.1

EINSTEIN Version 1.1 is the final version of EINSTEIN within the European project “EINSTEIN”.

This version has been used and tested in 90 energy audits in 6 European countries from October 2008 to July 2009.

With respect to Version 1.0 a significant increase of stability and bug-fixing has been carried out.

2.10. Version 1.0

EINSTEIN Version 1.0 has been released in October 2008 as first public version of EINSTEIN, mainly for its use within the training courses and the energy audits realized within the EINSTEIN project, although we are happy if also people from outside the EINSTEIN consortium start using and testing this software.

The present version of EINSTEIN is a version that is still under development within the EINSTEIN project and, therefore, is NOT yet a fully tested and reliable version.

Please check all the outcomes and calculations carried out by the tool before delivering results obtained with EINSTEIN to your customers.
