The EINSTEIN methodology is supported by an expert system software tool that guides the user through the whole auditing procedure spanning from data acquisition, processing and estimation to the design and quantitative (energetic and economic) evaluation of alternative solutions.

The EINSTEIN Software Tool is:

Modules of the EINSTEIN software tool

Consistency and Completeness Checking and Benchmarking

Breakdown of Energy Consumption and Supply by Processes, Equipment, Temperature Levels, Time

Pinch Analysis

Design of Optimised Heat Exchanger Network

Design of efficient Supply System (Utilities): CHP, Heat Pumps, Solar Thermal, Biomass, Efficient Chillers, Boilers and Burners

Dynamic System Simulation of the Whole System (Processes, Buildings, Distribution and Heat Exchanger Network, Utilities)

Economic and Environmental Evaluation

Automatic Report Generation

Data Acquisition and Analysis Module

Consistency and Completeness Checking and Benchmarking

Breakdown of Energy Consumption and Supply by Processes, Equipment, Temperature Levels, Time

The EINSTEIN software tool contains a questionnaire for structured and systematic data acquisition. Entered data is automatically checked for consistency. A procedure for estimation of non-available data is included. Using a benchmarking database, the current energy consumption of the company is compared with the typical standard values of similar companies or processes. The tool automatically generates a breakdown of the total energy consumption and supply by processes, utilities, temperature levels and time, both in graphical and in table format.

Heat Recovery Module

Pinch Analysis / Design of Optimised Heat Exchanger Network

The heat recovery module helps in designing and optimising an appropriate heat exchanger network for heat recovery and process integration. For this purpose, EINSTEIN analyses process and utility streams as well as available waste heat, and identifies the potential for heat recovery by pinch analysis. It takes into account energy demand and availability including the time schedules of processes.

Energy Supply & Renewables Module

Design of Efficient Supply System (Utilities): CHP, Heat Pumps, Solar Thermal, Biomass, Efficient Chillers, Boilers and Burners

The heat and cooling energy supply modules help to select and design the most appropriate energy supply equipment and distribution systems. EINSTEIN analyses the following supply-options: combined heat and power, heat pumps, solar thermal systems and biomass, efficient chillers, boilers and burners.

Simulation and Evaluation Module

Economic and Environmental Evaluation

EINSTEIN performs a dynamic system simulation (calculations on hourly basis) of the entire system (processes, distribution, heat exchanger network and supply utilities). Based on the resulting energy performance data an economic and financial evaluation is carried out. This analysis may be based on all parameters that influence the economic performance such as investment costs and depreciation, energy costs (fuels and electricity), operation and maintenance costs, and a lot of other cost concepts such as fees for legal requirements, income from sales of substituted equipment, etc.

As a result of financial analysis the user gets synthetic data on economic performance such as required investment, rate of return (IRR), pay-back and net present value (NPV).

Reporting Module

Automatic Report Generation

EINSTEIN automatically creates an exhaustive audit report that summarises the main results of the analysis on both the present state and the energy saving alternatives. The report (a spreadsheet in open document format) can be edited, printed and delivered to the audited company.
