ANNEX III Calculation of life-cycle GWP of new buildings pursuant to Article 7(2)
ANNEX III
Calculation of life-cycle GWP of new buildings pursuant to Article 7(2)
1. GENERAL FRAMEWORK
This annex sets out a Union framework for the national calculation of life-cycle GWP, with a view to the disclosure of the results in the energy performance certificate of the building pursuant to Article 7(2). For the verification of compliance with a limit value pursuant to Article 7(5), Member States may decide to leave out some parts of life-cycle stages and some parts of the scope of building components, for example by applying weighted coefficients associated with the date of emission during the building’s life cycle.
The life-cycle GWP of new buildings shall be calculated in accordance with the minimum requirements set out in this Annex and following the relevant parts of the standard EN 15978 (EN 15978:2011 Sustainability of construction works. Assessment of environmental performance of buildings. Calculation method) and taking into account any subsequent standard relating to the sustainability of construction works and the calculation method for the assessment of environmental performance of buildings. This does not constitute a legal codification of this standard.
The life-cycle GWP disclosed in the energy performance certificate (EPC) of the building shall reflect the as-built stage.
2. REFERENCE STUDY PERIOD
The life-cycle GWP shall be calculated over a reference study period of 50 years (
9
).
3. DATA FOR CALCULATION
Data issued in accordance with Regulations (EU) No 305/2011 (
10
) or (EU) 2024/3110 (
11
) of the European Parliament and of the Council, referred to as ‘data available under the Construction Products Regulation’ in Table 1, shall be used when available. If compatible with ‘data available under the Construction Products Regulation’, data issued in accordance with product regulations adopted on the basis of Directive 2009/125/EC, Regulation (EU) 2017/1369, or Regulation (EU) 2024/1781 of the European Parliament and of the Council (
12
), referred to as ‘data available under ecodesign and energy labelling legislation’ in Table 1, shall also be used. If such data are unavailable, other types of data referred to in Table 1 may be used. Member States shall ensure the highest possible accuracy and reliability of the results of the life-cycle GWP calculation and are encouraged to allow the use of project-specific or product-specific data which have higher quality and higher precision than generic data or default values.

Type of data
|
Definition and use
|
|
Data available under the Construction Products Regulation
|
Product data of climate change effects obtained from the declaration of performance and conformity (DoPC) under Regulation (EU) No 305/2011 or Regulation (EU) 2024/3110, including DoPC covered by a harmonised technical specification and DoPC issued in accordance with the relevant European assessment document and European technical assessment.
|
|
Data available under ecodesign and energy labelling legislation
|
Compatible data issued in accordance with product regulations adopted on the basis of Directive 2009/125/EC, Regulation (EU)2017/1369 or Regulation (EU) 2024/1781.
|
|
Project-specific data
|
Project-specific data calculated in accordance with standard EN 15804 or EN 50693 or a compatible standard, although not issued under Regulation (EU) No 305/2011 or Regulation (EU) 2024/3110 or product regulations adopted on the basis of Directive 2009/125/EC, Regulation (EU) 2017/1369 or Regulation (EU) 2024/1781. Those data may be used only if they are specifically permitted by national legislation.
|
|
Product-specific data
|
Product-specific data calculated in accordance with standard EN 15804 or EN 50693 or a compatible standard, although not issued under Regulation (EU) No 305/2011 or Regulation (EU) 2024/3110 or product regulations adopted on the basis of Directive 2009/125/EC, Regulation (EU) 2017/1369 or Regulation (EU) 2024/1781. Those data may be used only if they are specifically permitted by national legislation.
|
|
Average data for a product group in accordance with standard EN 15804 or EN 50693
|
Sectoral environmental data represent the average of multiple products from one or more companies and are provided by industrial associations or other equivalent organisations that cover the product. Those data may be used only if they are specifically permitted by national legislation.
|
|
Generic data
|
Generic environmental data calculated in accordance with standard EN 15804 or EN 50693 or a compatible standard for a group of products for a country or region. Those data may not be site or enterprise specific. Member States shall set clear rules as to how those data are to be generated or calculated, on the basis of similar existing product-specific data. Those rules shall be based on conservative assumptions, so as not to favour generic data on an unfair basis over product-specific data. Member States may establish generic data for reused construction products, taking into account the benefits of circular approaches.
|
|
Default values
|
Environmental data calculated in accordance with standard EN 15804 or EN 50693 or a compatible standard may be used to fill data gaps, where none of the above types of data are available, or where it is necessary to simplify the calculation. Default values may be set out for a specific scope of a building element or multiple building elements, or for a scope of a life-cycle sub-module or a life-cycle module, or multiple life-cycle sub-modules or multiple life-cycle modules. Member States may set default values with conservative assumptions that encourage the calculation with specific data when available. Member States may set a series of default values that ensures that the disclosure of the life-cycle GWP of new buildings, pursuant to Article 7(2), is possible even in the absence of any specific data.
|
Member States shall set out clear rules, with a consistent and conservative approach, to generate and update generic data and default values. Member States shall ensure that the necessary data, including generic data and default values, are made publicly available, allowing life-cycle GWP calculations for new buildings by the dates set out in Article 7(2), including in cases where project-specific or product-specific data are not available.
For data types other than data available under the Construction Products Regulation or under ecodesign and energy labelling legislation, Member States are encouraged to limit market fragmentation through the recognition of reliable and compatible available data issued in any Member State, including product-specific data and project-specific data calculated in accordance with EN 15804 or EN 50693 or a compatible standard. In any event, Member States shall take the necessary measures to ensure consistency and compatibility between data when combining those data from different sources and ensure that the final results for the life-cycle GWP are reliable.
4. USEFUL FLOOR AREA
The life-cycle GWP shall be expressed in units of kg CO2eq/m2 of useful floor area.
Member States shall set out how the definition of useful floor area is to be used in practice to calculate the life-cycle GWP of new buildings. The useful floor area shall correspond to the area of the parts of the building that are covered by the life-cycle GWP calculation and shall not extend beyond the building envelope. Member States shall describe at national level the adopted useful floor area in terms of component areas, as defined in accordance with International Property Measurement Standards (IPMS) (
13
) or an equivalent standard, which ensure the transparency, consistency and comparability of floor area measurements.
The life-cycle GWP shall be calculated and disclosed in the EPC of the building, in accordance with Article 19 and Annex V, or of the building unit where applicable. If relevant, Member States may set rules for allocating the emissions of building components shared by multiple buildings. Those rules shall ensure that the life-cycle GWP calculation is fair, transparent and consistent across different buildings and projects.
5. SCOPE OF LIFE-CYCLE STAGES
The life-cycle GWP shall be calculated for each required life-cycle stage, as set out in Table 2. Member States may decide to exclude any optional life-cycle stages from the calculation, as set out in Table 2.
For each life-cycle stage, when the information available at product level offers multiple scenarios, the calculation at building level shall be as representative as possible of the building project or building. When reliable information is not available, or a simplified calculation is relevant, Member States may decide to allow a default scenario to be used for the calculation, based on the worst-case scenario principle.
Member States may adopt default values for any life-cycle stages or sub-life-cycle stages in accordance with the requirements relating to data for calculation set out in Section 3 to fill data gaps or when it is necessary to simplify the calculation.

|
7. SCOPE OF BUILDING ELEMENTS AND TECHNICAL EQUIPMENT
The life-cycle GWP calculation shall include as a minimum the building elements and technical equipment listed in Tier 2 under the shell and core categories of Table 4. Member States shall ensure a comprehensive and accurate life-cycle GWP calculation, clearly describing at national level the building elements and technical equipment of a building required for the life-cycle GWP calculation. To this end, Member States may follow the examples shown in Tier 3 and Tier 4 of Table 4 and provide any substantial deviations in the national legislation.
Building elements and technical equipment or systems covered by the EPC of the assessed building shall be taken into account in the calculation if Member States consider that their ownership and maintenance is partially or exclusively the responsibility of the building owner (
14
), even if they are external to and structurally independent from the assessed building. When building elements and technical equipment are external to and structurally independent from the assessed building, the emissions associated to those building elements and technical equipment shall be taken into account in the embodied carbon and operational carbon analysis, but their floor area shall not be taken into account for the floor areas.
Member States may consider adopting generic data or default values for any of the elements mentioned in the tiers in Table 4, in accordance with the requirements relating to data for calculation set out in Section 3 to fill data gaps or when it is necessary to simplify the calculation.

|
|
Composite work, prefabricated work and sundries for ‘external buildings’ (10)
|
(1)
Insulation, waterproofing, screed, connections, fittings or elements for drainage, elements for services that are inserted or applied together with the substructural works but which are not already counted under specific entries in this Table 4 or elsewhere.
(2)
Fireproofing, insulation, waterproofing, screed, connections, fittings, ramps, permanent formwork, mezzanine structures, supports for tiered seating, maintenance routes or other elements that are inserted or applied together with the structural works but which are not already counted under specific entries in this Table 4 or elsewhere.
(3)
Fireproofing, insulation, waterproofing, screed, connections and fixings to the structure, fittings, ramps, shading devices, louvres, eaves, insect protection, grilled assemblies, parapets, railings, green walls, chimneys or other elements that are inserted or applied together with the external architectural works but which are not already counted under specific entries here or elsewhere.
(4)
Built-in refers to the incorporation of the relevant building features during the construction stage and prior to handover of the building to the owner.
(5)
Fireproofing, insulation, waterproofing, screed, connections and fixings to the structure or maintenance routes, framing, sealing, adhesives, floating floors, sprung floors, finishes, line markings, trim, skirting, fittings, ramps, grilled assemblies, parapets, railings, fireplaces or other elements that are inserted or applied together with the internal architectural works but which are not already counted under specific entries in this Table 4 or elsewhere.
(6)
Any other fixtures, fittings or other elements that are inserted or applied together with the building services, system and infrastructure but which are not already counted under specific entries in this Table 4 or elsewhere.
(7)
Any other fixtures, fittings or other elements associated with the installation of water, gas, electricity, heating, ventilation, above-ground drainage, telecommunications and other services, including ducts, protective coatings, holes, chases, sleeves, covers, fire stopping, labelling, and bases, etc, which not included elsewhere.
(8)
Refers to buildings that are external to and structurally independent of the assessed building, but which are located within the curtilage of the assessed building and servicing the assessed building occupiers and/or assessed building technical systems and infrastructure. Structural independence shall be understood as a lack of shared foundations and other load-bearing structural elements.
(9)
Parking facilities which do share structural elements and that fall within the envelope of the building structure shall not be considered as external buildings but instead as a part of the whole building, thus counting their associated embodied carbon, operational carbon and floor areas in the analysis. On the contrary, for independent parking structures that are considered as external buildings, their associated embodied carbon and operational carbon may be considered in the analysis, but not their floor areas. In cases where a parking facility is part of a shared structure between more than one building, either the whole complex of buildings shall constitute one single assessment, or the embodied carbon impacts and floor area of the parking facility shall be allocated on the basis of the relative shares of parking spaces that are designated to each building.
(10)
Any other fixtures, fittings or other elements associated with the construction of external buildings which are not included elsewhere.
