Industrial thermal energy (heat and cold) demand constitutes about 28 % of the total final energy demand and produces about 21 % of the CO2 emissions in Europe. Space heating and cooling in buildings contributes another 27 % to the final energy demand. Despite improvements in energy efficiency across Europe over the last decades, there remains a large unexploited potential for reducing energy demand which can be achieved by the intelligent combination of existing solutions and technologies. However, frequently the required investments are not made due to e.g. lack of knowledge and too few resources available for energy auditing.


The EINSTEIN-II project aims to contribute to a widespread implementation of integrated energy-efficient solutions for thermal energy supply in industrial companies with a high fraction of low and medium temperature heat demand and for non-industrial users of similar demand profiles, such as hospitals, commercial centres, large office buildings, district heating and cooling networks, etc. 


To further optimise thermal energy supply, a holistic integral approach is required that includes the possibilities of demand reduction by heat recovery and process integration, and by an intelligent combination of existing affordable heat (and cold) supply technologies, under the given economic constraints. The proposed project builds on the EINSTEIN tool kit for thermal energy auditing that has been developed within the previous IEE project EINSTEIN (Project EIE/07/210/SI2.446708). This tool kit, based on an expert system software tool, guides the user through the whole procedure from auditing (preparation of visit and data acquisition), to data processing, to the elaboration, design and quantitative (energetic and economic) evaluation of alternative solutions.


The EINSTEIN II project will go beyond what was achieved in the previous project, setting the following objectives:

  • consolidate the EINSTEIN thermal energy audit methodology and extend it to non-industrial uses

  • realise an intensive training programme with relevant actors (energy auditors ...) in additional countries, including the larger European countries (UK, France, Germany)

  • test and validate the improved and consolidated methodology in an audit campaign in the participating countries

  • development of standards and contribution to standardisation activities ongoing in the European Committee for Standardization - CEN/CENELEC Sector Forum Energy Management SFEM, in CEN/CENELEC BT TF 189 Energy Management and Related Services – General Requirements and Qualification Procedures, in CEN/CENELEC BT TF 190 Energy Efficiency and Saving Calculations, and in the CEN/CENELEC Joint Working Group Energy Audits


The EINSTEIN Expert-System Software Tool

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.


Training and certification

A standard training programme on the EINSTEIN methodology has been developed. This training programme consists of introductory and advanced training courses, together with the possibility for trainees to carry out a project work and obtain certification as an EINSTEIN energy auditor.
