1. On EINSTEIN

1.1. Overview

For optimising thermal energy supply in industry, a holistic integral approach is required that includes possibilities of demand reduction by heat recovery and process integration, and by an intelligent combination of efficient heat and cold supply technologies.

EINSTEIN is a tool-kit for fast and high quality thermal energy audits in industry, composed by an audit guide describing the methodology and by a software tool that guides the auditor through all the audit steps.

The main features of EINSTEIN are:

  1. the data processing is based on standardized models for industrial processes and industrial heat supply systems;
  2. special tools allow for fast consistency checking and estimation of missing data, so that already with very few data some first predictions can be made;
  3. semi-automatization: the software tool gives support to decision making for the generation of alternative heat & cold supply proposals, carries out automatically all the necessary calculations, including dynamic simulation of the heat supply system, and creates a standard audit report;
  4. a basic questionnaire helps for systematic collection of the necessary information with the possibility to acquire data by distance.

The software tool includes modules for benchmarking, automatic design of heat exchanger networks, and design assistants for the heat and cold supply system.

The base version of the EINSTEIN expert system software tool is available for free, as an open source software project. This type of software development has shown to be very efficient for dissemination of knowledge and for the continuous maintenance and improvement by user contributions.

Since Version 2.3, in parallel a commercial version EINSTEIN Plus is being developed by energyXperts.NET as a means of fund raising for maintenance and continuous development of the EINSTEIN project.

Other contributions:

Thanks to all partners of the European projects EINSTEIN-I and EINSTEIN-II (www.einstein-energy.net), for their ideas and suggestions, critical review, testing, the promotion of the software and the organization of the training workshops.

Thanks furthermore to the approx. 500 energy auditors that have been trained on and worked with EINSTEIN from October 2008 to July 2009 within the EINSTEIN-I project and from March 2011 to June 2012 within the EINSTEIN-II project, and to the other’s from the EINSTEIN users community for their comments, ideas, testing and bug-reports.

Special thanks to the following users for valuable comments and suggestions:

  • Uwe Dankert (udEEE Consulting, Haar, Germany): * detailed comments and suggestions for the EINSTEIN user interface (some of them already included in V2.2) * detailed testing of time schedules in combination with heat recovery calculations
  • Stephan Mücke (Energie- und Solarberatung, Dresden, Germany): * providing contacts and information about fluid property libraries (humid air, steam). Tips could not yet be included, but are on the list.
