The DIBU - German Institute is building and the environment e. V. an initiative of building products manufacturers, and as a manufacturers' group a closed public image of environmental product declarations (EPD) of eco-labels type III according to ISO and CEN standards. Members come from the timber materials, mineral materials and metals.
Winning a DIBU declaration includes an independent review and shows the quality of a product as well as the responsibility of the company in terms of sustainable construction.
product-related environmental information are now regulated by law. Currently takes the European Commission mandated CEN *- norm on the harmonization of environmental declarations on the road. (CEN is the abbreviation for comitee Européen de Nomalisation that at European level in almost all technical fields - including in civil engineering -. Is responsible for standardization)
was the DIBU declaration program for construction in close integration with civil and environmental authorities in Germany and the international standardization process. All are based on the international standard ISO 14025, which is required for all sectors, leading in the application is the construction industry. For it is currently being developed in the international standards organization is ISO CD 21 930 "environmental declarations of building products. The DIBU in Germany is currently the only organization that consistently declared after the previously agreed international standards.
Based on the analysis of the different information needs of buyers developed DIBU or its precursor, the AUB (Arbeitsgemeinschaft eV
environmental friendly building, criteria for the declaration of building products, eg in terms of
• toxic gas and hazardous particles
• emission of dangerous radiation
• Water and soil pollution
• Improper disposal of waste water, solid or liquid waste
• energy consumption and contribution to the greenhouse effect
• Life
your assessment involves the entire service life of a building. In addition, it includes the production of precursors, the building and the creation of recycling opportunities.
DIBU this case, the procedure is as follows:
The manufacturer assembles the relevant product data.
An independent committee of experts reviewed the data for completeness and plausibility. Where appropriate, it requires an additional statement, Evidence or tests. Unless it is considered justified, the DIBU Calls To maximize environmental
pretend more information, such as government institutions. The DIBU prepares the data for the public to understand and confirm the product information in a structured but non-assessed form. The applicant receives the certificate DIBU a "Produktbeipackzettel. About
the above self-declaration is also evaluating the data according to ISO 14025 Type III in two steps further by including an independent third party and can also check the data independently. It submits to the DIBU drawn up at international environmental declaration types for construction of the ISO.
Type III environmental labels (ISO 14025)
The type III contain general product-label, LCA and additional information. They will also be created based on criteria developed with the involvement of independent third parties and are also checked independently.
you are suitable for products that are used in conjunction with other systems.
Here is a summary of
declarations for ISO TR 14025 Type III
- are intended for trade, commerce and consumer
- provide umfangreiche quantitative Informationen
- beruhen auf einer Ökobilanz
- stellen Umweltwirkungen dar, ohne zu werten
- beziehen interessierte Kreise ein
- liegen in alleiniger Verantwortung des Herstellers
- Drittzertifizierung möglich
Nachfolgend eine Zusammenfassung für
Ökobilanzen DIN EN ISO 14040 – 14043
Ökobilanzen werden nachfolgend noch ausführlicher beschrieben. - wenden sich an Experten in Wirtschaft, Wissenschaft und Politik
- stellen die Umweltauswirkungen eines Produkts umfassend dar
- beruhen auf dem gesamten Lebensweg eines Produkts
- sind für alle Produkte und Dienstleistungen geeignet
- liegen the sole responsibility of the customer
- review by independent third parties may include mandatory
In Germany, a manufacturer of building products at the forefront of this new declaration. The market is large: planners, architects, building owners and tenants are increasingly interested in environmental and health information relating to construction. However, there are often end products. They develop their performance in general only in the later re-use in
components and structures, so their environmental effects can often only be assessed in the context of a structure. Against this background, the type III declaration a sophisticated tool for environmental information to incorporate and share a holistic view of structures or components.
, as an "organizer" for declarations by type III in Germany has the DIBU - German Institute of Construction and Environment developed eV, an association of building products manufacturers. To ensure transparency DIBU is connected to an external expert committee, belong to him, among other things, the German Institute for Building Technology, the Confederation of German Construction Industry, the Federal Environment Agency and environmental groups to. The expert committee set a general guideline for the development of product-specific requirements by type III. After developing this guide Vendor and interested parties, the product-specific requirements for certain product groups such as brick, aerated concrete, structural metal, wood materials or mineral fibers. The DIBU provides stakeholders with the requirements in draft on the Internet for discussion, according to the returns they are modified. The resulting environmental declarations of the external review committee of experts before publication
standard for construction in preparation
In many European countries created similar initiatives on environmental declaration
by type III. Given the special nature of construction, the interest is great, so on a separate standard for environmental declaration is developed by construction at the ISO level. The European Commission plans to award for the harmonization of the declarations under a mandate from the European Committee for Standardization.
LCA
LCA is a standardized tool. You enter the
environmental impacts of a product from cradle to grave. The results can be used for an environmental product. The DIN EN ISO standards 14040-14043 provide procedures for the elaboration and communication of life cycle assessments.
LIFE CYCLE IN THE SERVICE OF THE PRODUCT
- are intended for professionals in business, science and politics
- represent the environmental impacts of a product comprising represents
- based on the entire life cycle of a product
- for all products and services
suitable with LCA, the environmental impacts of a product over its entire life cycle examined, ie, from raw material extraction production and use to disposal. A life cycle assessment points to ways in which a product can be improved from an environmental point of view, and supports the product development.
four elements of an LCA
Depending on the objectives may be different LCA-consuming. The DIN EN ISO standards 14040-14043 give their sequence and the necessary elements are present: first
Scope
is the goal and scope of an LCA clearly
second LCI
establishes the material and energy flows through all steps of the life cycle:
incorporated as many kilograms of raw material, how much energy is consumed, which wastes and emissions produced, etc.
third
impact assessment evaluates the potential effects of the product for humans and the environment, that is, the quality of air and soil, consumption of non-renewable resources, etc.
4th Evaluation
represents conclusions and makes recommendations
