IEA EBC Annex 57 - Subtask 3: Evaluation Methods of Embodied Energy and Embodied GHG Emissions in Building and Construction


This report is one of the deliverables of the International Energy Agency Energy in Buildings and Communities programme (IEA EBC) Annex 57: “Evaluation of embodied energy (eE) and carbon dioxide equivalent emissions (CO2eq) for building construction”, dealing with the Evaluation of Embodied Energy (EE) and Embodied GHG emissions (EG) for Building Construction. The document was developed by Subtask 3 of the annex, aiming to present the different calculation methods, and a common and transparent reporting format for the evaluation of EE and EG (EEG) in building and building materials/elements.


This report presents the different types of data sources and calculation methodologies to evaluate the EEG of construction products, whole buildings, and parts and processes in the building industry sector, based on a common framework and transparent reporting format. The important technical features of each methodology are presented to ensure appropriate interpretation and application of results, and thus, facilitate improved stakeholder and context-based decision-making.


The key elements of a generalised embodied impacts evaluation process are: dataset preparation and organisation, evaluation calculation methods, output formatting and documentation and application of results for a specific purpose and/or decision-making context. The document covers all these key elements.
