— a cradle to gate EPD with options: modules Al, A2 and A3 mandatory, a mandatory description of a scenario for module AS including the necessary activities to obtain the final insulation product out of the product. The other modules optional (i.e. cradle to gate and selected further life cycle stages);
— a cradle to grave EPD: modules A to C mandatory.
3) EPDs for products to be used as in situ thermal insulation products including installation:
— a cradle to gate EPD with options: modules Al, A2, A3 and AS mandatory, the other modules optional (i.e. cradle to gate and selected further life cycle stages);
— a cradle to grave EPD: modules A to C mandatory.
5.3 Comparability of EPD for construction products
In principle, the comparison of products on the basis of their EPD is defined by the contribution they make to the environmental performance of the construction works. Consequently comparison of the environmental performance of construction products using the EPD information shall be based on the product’s use in and its impacts on the construction works, and shall consider the complete life cycle (all information modules).
NOTE This is especially true for insulation products of which their main purpose is to reduce the energy consumption in the use stage of buildings. Since the reduction of the environmental impacts due to energy savings during the use stage is in most cases much higher than the environmental impacts of the insulation products themselves, it makes more sense to Focus on good performance on building level during use than on comparing insulation products.
End use applications are defined in Annex A. Cradle to grave analyses shall describe all relevant requirements for the end-use application of the product.
5.4 Additional information
As in EN 15804 and additional Annex A of this European Standard.
If benefits of insulation products due to energy saving during the installed life are reported in relation to the environmental performance of a building, they shall be reported as additional information. The environmental impacts shall be calculated using EN 15978. The benefit is the difference between the impacts of at least two insulation levels for the same building considered over the whole life cycle. The scenarios shall be fully described in the EPD and sufficient information given to the verifier to verif’ this.
5.5 OwnershIp, responsibility and liability for the EPD
6.3.1 Functional unit
As in EN 15804 and in addition clause 5.2 of this European Standard, a functional unit shall contain the R-value for the applications as listed in Annex A. If the R-value is not relevant for a specific civil engineering application, the relevant function for that application shall be defined instead.
6.3.2 Declared unit
The declared unit is defined as:
For batts, boards and similar:
I m2 thermal insulation product for a specific Rp-value of the product as placed on the market intended to be used for any of the application(s) listed in Annex A or used as generic insulation. Calculation rules can be added for other RI) -values.
Conversion factors may be added to translate from m2 and Rvalue to one or more of the other required unit types in EN 15804: item, mass (kg), length (m), volume (m3).
For pipe sections:
1 m’ thermal insulation pipe section product with the declared lambda, diameter and thickness, as placed on the market or used to insulate a pipe. Calculation rules can be supplied to account for the various thicknesses, diameters and densities.
Conversion factors may be added to translate from m’ to one or more of the other required unit types in EN 15804: item, mass (kg), area (in2), volume (m3).
For civil engineering applications:
1 m thermal insulation product with the declared lambda, as placed on the market intended to be used for the application(s) listed in Annex A or used as generic insulation.
Conversion factors may be added to translate from m3 to one or more of the other required unit types in EN 15804: item, mass (kg), area (m2).
Grouping of products shall follow the rules of EN 13172, but should ensure that any deviations due to intra- or extrapolation are less than 25 %, as described in Clause 6.3.6 of this European Standard.
6.3.3 Reference service life (RSL)
As in EN 15804.
A RSL linked to a specific application defined in Annex A can be declared. The parameters used to determine the RSL such as in use conditions etc., shall be declared in line with the applicable ISO standards (as in EN 15804),
NOTE The thermal performance characteristics of thermal insulation products are usually based on a minimum of 50 years.EN 16783-2017 pdf download.
