Ecodesign Preparatory Study – Steam Boiler

The Ecodesign Directive (Directive 2009/125/EC) establishes a framework for the setting of Community Ecodesign requirements for energy-related products with the aim of ensuring the free movement of such products within the internal market. This study provided the European Commission with a technical, environmental and economic analysis of steam boilers according to Article 15 of the Ecodesign Directive 2009/125/EC.


To prepare draft implementing measures for products under the Ecodesign Directive, the Europe-an Commission shall make a series of analyses and assessments, which are being called Prepara-tory Studies along a harmonized methodology. The methodology is described in the Methodology for Ecodesign of Energy-related Products (MEErP).

The MEErP consists of 7 Tasks, whereas Task 1 to 4 have a clear focus on data retrieval and initial analysis and Task 5 to 7 have a clear focus on modelling. It is prescribed that Task 1 to 4 can be performed in parallel and Task 5 to 7 sequential. Detailed information on the tasks is available in the report on the MEErP.

* BAT = Best Available Technology, BNAT = Best Not (yet) Available Technology
** LCA = Life Cycle Assessment, LCC = Life Cycle Cost

This study was carried out by PwC, Fraunhofer ISI and the National Technical University of Athens:

ICCS-NTUA participated in this project through its Decision Support Systems Laboratory EPU-NTUA in co-operation with experts from the Laboratory of Steam Boilers and Thermal Plants of NTUA (LSBTP-NTUA). EPU-NTUA is a multidisciplinary scientific unit which carries out research and development projects and provides high level consulting services on a wide range of complex societal and technical problems. EPU-NTUA operates within the School of Electrical & Computer Engineering of the National Technical University of Athens, the oldest, most prestigious and most competitive academic institute in Greece. LSBTP- NTUA has been working for the last 30 years on: The measurement and standardisation of warm water and steam boilers, the examination of phenomena which affect and determine the process of combustion in furnaces of conventional and non-conventional steam boilers, the energy exploitation of low rank coals and other fuels of poor quality, i.e. biomass and/or waste with biogenic origin, decentralized energy systems, power-to-gas.
