A new CEN Workshop is being established to expand on the innovative deliverables of the CHRONICLE research project. The project’s vision is to improve building performance in terms of energy efficiency, comfort, and well-being through the digitalization of building information.
Buildings play a significant role in global greenhouse gas (GHG) emissions, accounting for approximately 40.3% of total energy consumption and 34.4% of CO₂ emissions in the European Union (EU) alone. Therefore, the built environment is a critical sector for achieving the carbon neutrality goals established by the EU for 2050.
The revised Energy Performance of Buildings Directive (EPBD) aims to ensure that the building sector contributes to the overarching goal of reducing net greenhouse gas emissions by at least 55% by 2030. One of the overarching objectives is the decarbonization of EU's building stock, reducing the energy demand and promoting the use of renewable energy sources.
This Workshop is based on several deliverables of the CHRONICLE project, such as “dynamic Level(s) approach for building and LC performance assessment (2.2)” and “tool suite for WLC assessment and climate neutral building renovation planning (4.3)”. More specifically, the Workshop proposes the calculation of the carbon bill of buildings based on the GWP defined in EN 15978 and the price for emissions allowances in Europe. Based on calculation, the carbon bill of the refurbishment is defined as the difference between the carbon bill of the existing building and the carbon bill after the renovation, both with a lifecycle perspective. It is intended that the CWA as an outcome of this Workshop can be used to support the “polluter pays” principle from a “positive” perspective, encouraging renovations that reduce the carbon footprint over the life cycle of a building.
The kick-off meeting for the Workshop is planned to take place remotely on March 31st 2025 from 9.30 a.m. to 12.30 p.m. (CEST).
All interested parties are invited to submit comments on the draft Project Plan using the commenting form below, to the Workshop secretary (UNE) Aitor Aragon Basabe (aaragonb@une.org) by March 14th, 2025.
For more technical details, please refer to the draft Project Plan, which contains all relevant technical information. Additionally, comments or observations can be submitted via the dedicated commenting form below.
