An EPD (Environmental Product Declaration) is a multipage document describing the environmental effects of building products based on a life cycle assessment with quantitative data. It is created by the manufacturer and reviewed at the IBU by independent verifiers on the basis of ISO 14025 and EN 15804 norms, and is subsequently published.
An EPD serves to provide transparency to the public regarding the environmental influences of building products. It is the basis for the ecological evaluation of buildings in building certification systems such as the DGNB or BNB systems, or LEED, BREEAM, and HQE. In addition, EPDs clarify the optimisation potential over the lifetime of their products to manufacturers, who, as a result, can establish processes that conserve more resources, are more environmentally friendly and more economical.
Collecting the necessary data for the EPD, calculating the life cycle assessment and creating an EPD that conforms to the norms is the responsibility of the manufacturer. Normally, if the appropriate know-how is unavailable at his/her own company, the manufacturer will hire an experienced life cycle assessment service provider for support with the creation of the EPD. A list of companies and experts who have already successfully taken over these kinds of projects for EPDs with the IBU may be found in our list of cooperations in section 2 – LCA Practitioners.
IBU offers the following types of EPD to ensure that the appropriate EPD is created for each application:
For individual companies
- Project EPD
– Declaration of a product from a company’s plant for a specific (construction) project (usually created with an EPD tool) - Specific EPD
– Declaration of a specific product from a company’s plant
– Declaration of a specific product from several plants of a company - Average EPD
– Declaration of an average product from a plant of a company
– Declaration of an average product from several plants of a company
For industry solutions (e.g. associations)
- Specific EPD
– Declaration of a specific product as the average of several manufacturing plants - Average EPD
– Declaration of an average product as the average of several manufacturing plants - Worst case EPD
– Declaration of the effects of a product on the basis of a manufacturer survey for a product group - Model EPD
– For products with essentially the same material composition, the product with the greatest potential environmental impacts (worst case product) may be selected and declared as representative of any other product in the same class or group. - Individualization of manufacturer group declarations
– Limited individualization. The declaration ownership remains with the association and is indicated in the EPD
– Advanced customization of model EPDs (worst case EPDs) of a manufacturer group for a specific product under their own name
Verified tool solutions
- LCA tools are partially automated and require manual data entry of the product system’s inputs and outputs to create an EPD. After the tool has automatically calculated the EPD environmental indicators, the tool operator must enter them and other product-specific information into the EPD form on the IBU EPD Platform. Each EPD generated in this way is subject to an individual, simplified verification.
- EPD tools generate EPDs fully automatically and independently of the IBU EPD Platform. Typically, product-specific data (e.g. material lists) that is already available in a company’s software system or product configurators is linked to relevant life cycle assessment data. The verified evaluation system of the EPD tool calculates the results of the EPD environmental indicators, which, together with other required product-relevant information, are automatically entered into a defined EPD form. EPDs created by the tool operator using an EPD tool no longer require individual verification before publication
The EPD creation process can be divided into three steps:
Step 1: Development of Product Category Rules
The basis of an EPD is the guidance document (PCR – Product Category Rules), which consists of two parts. Part A, which is uniformly valid for all product subgroups, is written and maintained by the Advisory Board (SVR). It contains the algorithm for the life cycle assessment and the requirements of the underlying background report.
Part B is written for specific product subgroups and describes the requirements for the contents of the respective EPD. Working groups moderated by the IBU define the respective product subgroups, which exhibit similar characteristics and functionalities. They specify the structural data and the additional environmental and health-related evidence that is to be declared. IBU members, working together with external experts, thereby compile a draft of the new PCR Part B guidance text.
The SVR examines the draft for consistency between the product groups and for completeness. Subsequently, interested parties from the public have the opportunity to discuss the draft in an online forum and to contribute suggestions for improvement, before the SVR releases the document.
Step 2: Data collection, LCA and EPD creation
The collection of all necessary data is a basic prerequisite for the calculation of a life cycle assessment and for creating the EPD in accordance with the standard. Usually the manufacturing company commissions an experienced life cycle assessment service provider to do this.
The EPD has to be created on the basis of the guidelines of PCR guidance text Part B. For the writing of the EPD document itself, an easily operated, web-based Online Tool, accessible to all participants, is available.
In order for the results of the life cycle assessment to be checked, an additional “background report” based on PCR Part A must be drawn up. The underlying life cycle assessment model comes from this report, as well as the acceptance and allocation methods.
Step 3: Independent review and confirmation
In the third step, the EPD and the background report are reviewed by the verifier appointed by the SVR as an independent third party, in accordance with the principles of ISO 14025 and EN 15804. Following a review for completeness, plausibility and consistency of the data and calculations, a verification report is completed.
Subsequently, the EPD is published by IBU. An EPD is valid for 5 years.
According to DIN EN ISO 14025, product category rules are the combination of specific rules, requirements, or guidelines used to create an Environmental Product Declaration for one or more product categories. In the IBU’s EPD programme, the PCR is divided into two parts: A and B. PCR Part A contains the uniform life cycle assessment calculation rules for all building products, as well as the requirements for the background report. Part B regulates the specific requirements of each product subgroup for the contents of an EPD.
IBU has no basic requirements for the software used to calculate the LCA. The use of Umberto, SimaPro, openLCA and other tools available on the market is generally permitted.
IBU’s EPD platform is not itself a tool for LCA calculation or a database for LCA data, but is used to enter, verify and publish the final EPD data in a standardized and digitized format. IBU is not involved in the upstream step of preparing the LCA.
In principle, the EPD platform or an EPD tool verified by IBU must be used to create (enter data) and submit the EPD. The requirements for EPD tools and LCA tools are set out in the General Program Instructions.
IBU does not impose any general restrictions on the selection of background databases. However, there are often corresponding specifications for EPD applications on the market and in certification systems to ensure a database that is as uniform as possible for users of EPD data. which must be taken into account when selecting for EPD creation depending on the target market; IBU will be happy to provide you with information on this.
The main basic documents are:
- EN 15804 +A2
- General Terms and Conditions
- General Programme Instructions
- PCR Part A (as a basis for calculation and the background report, available on the EPD online platform)
- PCR Part B (basis for EPD content and at the same time an EPD template in the EPD online platform)
- Current decisions of the Advisory Board
and the IBU Statutes, Fee Schedule and EPD Fee Schedule. For further information, please see Membership.
We explicitly point out that only EN 15804+A2 forms the basis of our field of activity. The creation, processing, adaptation or other modification of EPDs according to EN 15804+A1 is no longer carried out, as the transition period expired in October 2022. In justified exceptional cases, however, a re-examination or adaptation may be necessary.
The costs for the review and publication of the EPD are documented in the IBU-Fee Schedule. The costs for an EPD, called declaration fees, are divided into two parts:
- The one-time verification costs of 2.000 € for each EPD, and
- the annual trade mark use fee, tiered according to the number of EPDs (€960 to €120).
The costs for the accompanying IBU membership may be found in the Membership dues regulation. The membership costs are tiered into several contribution classes, based on the member’s total sales.
The entire process for an EPD is complex and usually takes several months. In particular, the data collection and calculation of the life cycle assessment by your LCA practitioner are time-consuming.
The verification of the EPD data by the independent verifiers via IBU varies greatly from case to case, depending on the quality of the EPD, how quickly the EPD creator makes the necessary corrections after receiving feedback from the verifier, and how many EPDs are currently to be verified.
Verification by the independent third verifier is a thorough process that ideally takes about 8 weeks. However, due to the current high demand for EPDs and the limited availability of verifiers, this process is taking longer. At the moment, you should expect a verification time of about 6 months. In addition, there is an editorial pre-check and the final approval by the IBU after successful verification. We are working hard to increase capacity and speed up the process.
We understand that these are longer waiting times than you may be accustomed to and ask for your understanding. To ensure that your EPD is available on time, we recommend that you include verification in your planning at an early stage.
You can view the basic PCR document for all product groups, PCR Part A, if you are registered on the IBU EPD Platform (epd-online.com) and have been authorised to edit documents. You will find PCR Part A under the “EPD Information” tab or as an attachment to the EPDs you have created.
All current PCR Part B documents are also stored on the EPD platform and can be downloaded. You can access them as soon as you are registered.
Independent verification of EPDs is stipulated by ISO 14025 and EN 15804, and indicates that the EPD has been tested and approved by an independent expert (verifier) prior to publication. The review contains the following criteria:
- Plausibility
- Completeness
- Consistency
Using the EPD-Online Tool, the manufacturer submits its EPD to the IBU to be verified. The IBU selects a verifier from the verifier committee and assigns the EPD, allowing the required documents (EPD, background report, or other additional verification documents, if possible) to be made available to the verifier. In the event of questions or discrepancies, the verifier contacts the manufacturer so that the EPD can be revised. If all of the data is correct, the verifier releases the EPD so that it can be published by the IBU. The independence of reviewers is very important to the IBU, and therefore the IBU, rather than the manufacturer, selects the verifier. For this reason, the verification costs are not paid from the manufacturer to the verifier, but rather, the IBU charges a lump sum and pays the manufacturer for the verification.
The Verification is a document check. There is no on-site inspection.
If there is no suitable PCR Part B for your product at IBU yet, please contact the IBU office. We will develop the PCR together with you and. The PCR process is free of charge. Only expertise and time are to be contributed.
EPDs from the IBU are generally recognised worldwide. Based on EN 15804+A2, the EPD complies with the European standard and is accordingly accepted by users in Europe and worldwide.
- IBU is a member of the ECO Platform. Its aim is to standardise the rules and Europe-wide validity of EPDs.
- IBU has reached mutual recognition agreements with other programme holders. If an agreement for mutual recognition exists between two programme operators, the declaration owner may also have EPDs published in the other EPD programme without another review of the EPD or the creation of a new EPD. The current mutual recognitions are listed here. Special features may need to be taken into account when creating EPDs.
Exceptions are sometimes country-specific requirements that go beyond the EPDs; here IBU can provide information. In addition to EN 15804, there are national peculiarities in the EPD creation rules in France, Italy, the Netherlands and the USA.
DIN EN ISO 14025 (often shortened to ISO 14025) “Environmental Trademarks and Declarations – Type III Environmental Declarations – Principles and Procedures” is the basis for environmental trademarks in compliance with Type III. ISO 14025 regulates, among other things, how Type III Environmental Declarations and Type III Environmental Declaration Programmes are created and in particular, specifies the application of the DIN EN ISO 14040 series of standards for their creation. This enables comparisons between products that have the same function – on the basis of quantified environmental information from the life cycle of a product.
The assignment of the verifier to the individual EPD projects is done by the employees of the IBU branch office, in accordance with the experience and area of activity of the individual verifier, as well as their availability.
The verification costs are charged to the declaration owner by the IBU in a lump sum of € 2.000 per EPD. This process of manufacturer-neutral assignment and payment of reviewers ensures the independence and quality of the IBU, and serves as a fundamental element of our claim to credibility.
DIN EN 15804 (often shortened to EN 15804) “Building Sustainability – Environmental Product Declarations – Basic Rules for the Product Category of Building Products” ensures that all EPDs for building products, building services, and building processes are derived, verified, and represented in a uniform manner. It stipulates the fundamental product category rules (PCR). According to EN 15804, EPDs in the building industry will form the basis for the description and evaluation of buildings. They thereby specify ISO 14025 for building products.
In order to avoid re-calculating and re-verifying the EPD again, it is possible to publish a translated version through the IBU. To do this, a certified translation is required. Through the request for this authentication, the IBU ensures that the contents of the original EPD and the translation are identical and are not merely advertising statements or modified data.
The translator may be freely selected, on the condition that he/she is certified by a notary public to issue certified translations. The IBU office can provide contact information for agencies experienced with EPD translations.
Aside from the choice of translator, the translated German-English and English-German EPD contents must be transferred to the EPD-Online Tool before the IBU publishes them. To aid in this, the branch office can set up a data record copy into or out of English, so that the contents, and, in particular, the tables, are already available. At that point, the translated texts (and if necessary, the graphics) can be inserted. The certification is added as an appendix (the title page of the translation, with the authentication stamp as a scan), with which it is certified that the translated contents from the original EPD have been accepted without changes.
The EPD Platform is a database system that facilitates the online creationof EPDs. The advantages of this tool are that every EPD maintains the same layout and, during the creation process, is always the most current version of an EPD. In addition, all IBU EPDs are published there.
- Multi-user functionality with different authorisation levels
- Completely digital processing of EPD creation, verification and publication
- Publication of digital twins in IBU.data and the ECO-Portal
- Free interface to ÖKOBAUDAT
The EPD Platform is available following a two-stage registration:
- Stage 1: for viewing published EPDs;
- Stage 2: for creating EPDs, click on “Create My Own EPDs”.
The second stage will be activated by the IBU office. The multi-user functionality of the tool makes it possible for any number of people to work on a particular EPD document within an EPD. Various safeguards ensure that two people cannot simultaneously edit the same section of the EPD.
In order create to a data record for the official German ÖKOBAUDAT building materials database it is a prerequisite that the EPD has been created in the EPD online tool and that it has already been published. Please note that the data records must first undergo an initial evaluation by the Ministry before they can be published in the database. ÖKOBAUDAT updates take place at regular intervals, meaning that new EPDs will not be listed immediately, but only with the next update. The transmission of data records to ÖKOBAUDAT is free.
The automatic transfer of EPDs to ÖKOBAUDAT via the IBU is not possible, since the individual declaration owner is also the owner of the EPD and must actively agree to publication in ÖKOBAUDAT.
The currently valid EPDs published by IBU can be found on
- the IBU website and
- the EPD-Online Tool (following free registration)
- as digital XML file on IBU.data
At Institut Bauen und Umwelt e.V., two different EPDs are generally offered: the IBU EPD and the “Core EPD”, in accordance with EN 15804. The primary difference between these two types of EPD is the extent of information provided. The Core EPD contains only normative mandatory required contents. Specifically, this means that a Core EPD, among other things, contains no data regarding the production, product processing, conditions of use, disposal, or the behaviour of the product in unusual circumstances. Further, neither Chapter 6 (Life Cycle Assessment Interpretation) nor Chapter 7 (Evidence) are included. These missing chapters significantly reduce the usefulness of the EPD in comparison to a complete IBU EPD, which is why, in order to supply information that is as concise and comprehensive as possible, the IBU normally recommends the creation of an IBU EPD.
In the “Project-specific EPD” tab, you will find EPDs that are valid for a specific (construction) project. These are usually created using fully automated EPD tools.
Product life cycle description
1. Chapter: General statements
These contain, among other things, basic information about the manufacturer, the product declared, the range of the validity of the EPD, and the date until which the EPD is valid.
2. Chapter: Product
This contains, among other things, a detailed product description, the specific intended purpose of the declared product, a description of the most significant (building) technical data for the product, information regarding placement on the market and application rules, specifications for the raw and auxiliary materials of which the product is composed, a description of the production process, as well as the behaviour of the product under unusual influences. Furthermore, it contains information concerning the installation, use and disposal of the product.
3. Chapter: Life cycle assessment algorithms
These describe, among other things, the unit declared, the system limitations, cutting-off rules, background data, data quality and applied allocation processes with life cycle assessments.
4. Chapter: Life cycle assessment scenarios and additional technical information
These document the life cycle assessment on the building level and necessary scenario information, e.g., reference service life, or expenditures for cleaning during use.
Life cycle assessment data
5. Chapter: Life cycle assessment results
This contains the life cycle assessment results in accordance with EN 15804 and ISO 14040ff.
Additional data
6. Chapter: Life cycle assessment interpretation
This contains a dominance analysis as well as a description of the gap or variance of the results in order to make possible a comprehensive understanding of the life cycle assessment values.
7. Chapter: Certification and test results
This contains additional environmental or health-relevant statements, e.g., regarding the emissions behaviour of the product (keyword VOC emissions).
8. Chapter: Reference works
This is a listing of all norms, standards and key documents used that apply to the declaration.
Supplement to the core EPD:
At Institut Bauen und Umwelt e.V., two different EPDs are generally offered: the IBU EPD and the “Core EPD”, in accordance with EN 15804. The primary difference between these two types of EPD is the extent of the information provided.
The numbering is structured as follows:
EPD_KKK_JJJJLLLL-DSRV-SP
- K = company identifier (capital letters only)
- J = year
- L = serial number beginning with 0001; this will be generated by the system and is reset to 0001 at the beginning of each new year
- D = type of declaration:
- C = core EPD;
- I= IBU EPD
- S = system boundaries:
- A = cradle to gate;
- B = cradle to gate with options;
- C = cradle to grave
- R = representative status
- A = declaration of a specific product from a manufacturer’s factory;
- to H = declaration of an average product averaged from several factories of several manufacturers, not representative of the association;
- V =version; the current version begins with 1; changes to the EPD can be made using a version number.
- SP = language abbreviation
IBU.data is a data base, provided by IBU containing the LCA-based data from the EPDs of building material manufacturers, digitised i.e. made available to the public in machine-readable XML format. This enables the application for calculating building LCA.
With IBU.data, the IBU offers considerable added value for users of EPDs:
- The in-house database is accompanied by short publication cycles for new EPDs
- The in-house operation means that all IBU EPDs can be made available digitally
- Dependence on the specifications and requirements of external database operators is reduced
The basis is the concept of the InData working group, a European EPD initiative dedicated to building a data network of digital EPD data as XML files in the ILCD+EPD format based on the ILCD (International Life Cycle Dataset).
IBU.data publishes all EPD datasets that have been created and published by IBU via the EPD platform. Thanks to the direct connection to the EPD platform, IBU.data always contains the most up-to-date data.
In addition, all fully automated EPD tools are obliged to make all EPDs created with them available as a digital twin.
Note: We are currently facing technical issues which cause delays of transfers to ibu.data. We are working on this. For further information please reach out to verification@ibu-epd.com (Date 03/2025).
Use of the data offered on IBU.data is free of charge for end users for the purpose of information and use for Building LCAs. Click here for the terms of use. A separate licence agreement is required for all other types of use. Please contact info@ibu-epd.com for more information.
EPDs are the fundamental data for building LCAs and basis used for the ecological pillars of sustainability assessment in building certification systems: In the DGNB system and in the BNB, EPDs are applicable for individual building products, in order to calculate the building’s life cycle assessment. With LEED, credit points may be earned through the existence of EPDs, which is similar in function to BREEAM.
Further, through the data collection and evaluation that takes place in the process of creating an EPD, manufacturers are able to gain insights into their own processes. Through the life cycle analysis, the building product can be checked for ecological and economic hotspots, and can be subsequently optimised, not only conserving resources and reducing the environmental effects of the product, but also bringing financial savings through increased efficiency in the process.
The EPD is thus not only data source and an informational document for planners, architects and auditors, but also a valuable instrument for the manufacturer in optimising his/her own products and processes.
Companies have the opportunity to become full members of the IBU, or to place EPDs with the IBU through an association in which it is a member, which is also a full member of the IBU, as long as the applicable product group falls under the activities of the association.
As full IBU members, associations may forward their authorisation for EPD creation on to their membership organisations. This option does not apply for associate members of the association. In this case, the association may decide to exclusively create association EPDs so that its members may not create individualized EPDs or their own EPDs through the association. If this is requested, the company itself must become a full IBU member.
In addition, it is possible to become a supporting member of the IBU.
The general public does not currently have access to the website. If you are interested in accessing IBU.data from a building LCA tool via the online interface, please contact info@ibu-epd.com for more information.
For membership at IBU, a written application must be submitted to the IBU office, with a completed application form.
The Board of Directors makes the decision on admissions. The rules for membership are regulated in the Bylaws and Membership Fee Regulations.
The logos are available for download by IBU members. When using them, please observe the trademark use statutes.
To the extent that you would like placement of EPDs in foreign markets where the IBU has mutual recognition with an EPD program, the IBU branch office is available to assist with implementation. The IBU recommends making a decision during the creation of the life cycle assessment as to whether or not you will ultimately make use of mutual recognition, in order to perform potential additional calculations at that time, and thus reduce costs and time.
The ECO Platform is the umbrella organisation of the various national EPD program operators in Europe, and supports the creation of a European Core EPD system based on the EN 15804 European standard. The European program operators involved have agreed upon certain minimum standards in relation to quality management and the verification procedure, whose observance they have obligated themselves to. EPDs that carry the ECO Platform EPD logo and are listed on the ECO Platform stand for the best possible comparability to date in terms of a coordinated European solution.
The ECO Platform initiative, which is the basis for the creation of international recognition, has been well-received in the industry. Along with IBU, as program operator in Germany, the founding members of the ECO Platform also include the European building materials association Construction Products Europe.
For manufacturer data on specific contents of the EPD, please contact the declaration owner directly. You can find general contact information for the declaration owner and those responsible for the contents of the EPD on the last page of the EPD document.
IBU generally does not provide evaluations and recommendations concerning individual products, since building products are normally semi-finished products. Their efficiency and environmental effects unfold only in interaction with other products in specific installation situations. For this reason, building products are neither “good” nor “bad”, and the key numbers of the life cycle analysis in EPDs are normally not directly comparable. Evaluation and comparison is only meaningful on the complete building level, not with individual products!
Product seals‚ quality labels or seals of quality are designated as certificates for products, providing graphic or written product identifiers that certify the quality of a product, for example, regarding safety criteria adhered to, or product contents. Certificates are an evaluation of a product. The EPD does not provide these, because it provides quantitative information about the characteristics and environmental effects of a product and makes these transparent, without making evaluative statements.
This difference, as compared to traditional environmental labels and certificates or seals of quality, is consciously normatively regulated with EPDs, since, here, a life cycle assessment with a multitude of indicators is shown, which cannot be summarised in a single evaluative statement. For instance, an EPD does not test the product for specific characteristics, such as material content or emissions, as is the case in laboratories. On the contrary, verification examines whether the data provided by the manufacturer in its EPD are plausible and complete with regard to applicable standards and rules.
In order to receive up-to-date information about the IBU, subscribe to the IBU newsletter or follow us on LinkedIn.
The IBU is an initiative of building product manufacturers who operate as a registered association. The association is currently formed by around 330 member companies and associationsfrom the building materials industry inside and outside of Germany, who are involved in sustainable building.
The board of 15 people is elected at the general meeting, with the chair of the board as its head. In addition, an elected president represents the IBU in public and in strategic tasks.
The Advisory Board (SVR) represents the highest technical authority for the IBU’s work. Approx. ten experts from science and standardisation, building and environmental protection authorities, as well as nature conservation associations voluntarily participate in supervising conformity to norms and ensuring the quality of the verification procedures in the IBU EPD programme.
The IBU uses independent third parties to review the EPDs. These include verifiers from SVR-appointed experts from science and standardisation, and from testing and certification institutions who have comprehensive knowledge of products, methods and standardisation. Before they are certified by the SVR, they go through a supervision phase, in which they are guided by experienced verifiers during their practical training. In addition, they commit themselves to continuous further training within the context of the IBU programme.
