8. Tips & Tricks

In this section some tips & tricks are collected for the work with the current versions (V2.2 / V2.3plus).

Features that are not yet - or not yet fully - working are highlighted and some possible workarounds are mentioned.

You can also see and add your own items at:

8.1. Data Entry - general issues

  1. It is not possible to change the name of an existing equipment, process etc once it has been created and saved. The tool will automatically add a new item to the list with the new name (in addition to the existing ones).
Workaround: If You want to change the name, create a copy with the new name and delete the old one. Take care: Connections from / to this equipment / process / pipe etc. then have to be established again.
  1. Refresh of windows
  • Lists for selection of parameters are not updated automatically in the questionnaire panels. E.g., if a new fluid is added into the DB while data entering, in order to view the new fluid in the pop up list close and enter again the window in use (e.g. the process questionnaire).
  • In order to view a New project or an imported one among the “ project in the database” go to the EINSTEIN main screen and then go back again to “Einstein industry data”

8.2. Consistency Checking and Energy Statistics

  1. Only annual and monthly data are available. Daily statistics are not yet implemented
  2. In order to get familiar with the data input and the consistency-check concept, it is recommended to try to perform the example 4.2 (Project Einstein Guide 4.2 Basecase) according the description given within the Audit Guide.

Following a simple procedure for data entering may help to pass the consistency check in a shorter time.

It is recommended to enter the process’ data first, then the equipment’s (but without any boundary such as the load factor), then the pipes’ and last the overall consumption. Of course in order to perform the consistency check equipments and pipes have to be previously created and linked each other and to the processes – but without adding any specific parameter such as the power etc.

It is also recommended to analyse sub-system by sub-system (e.g. Enter data of equipment 1 -> related pipes -> related processes THEN check the consistency and enter the second group of data equipment 2 -> related pipes -> related processes…).

8.3. Benchmark Module

Not yet fully tested. Operations with the benchmark module may cause instabilities. => Use it on your own risk.

8.4. Heating and Cooling Supply

Biomass. Not yet supported explicitely, however you can define any biomass as fuel within the fuel data base.

8.5. Boilers and burners

For automatic design of boilers and burners, only natural gas fired boilers are considered.

8.6. Economic analysis

  1. Some elemental economic data should be filled in the questionnaire at the very beginning (fuel and electricity price, general economic data and operation and maintenance costs).
  2. For new equipment, and where no explicit information is given, EINSTEIN assumes default values for investment, O&M costs and funding rates. Critically revise these estimated values before relying on the results of the financial analysis.
  3. The results of the economic analysis are not fully writen into the Report. In the page 4.7 of the Report, the data of Modified Internal Rate of Return and Benefit and Cost Ratio are still missing. You can find these data in the tool from the last panel of the Comparative Study.
