Sustainability requirements for construction products in the QNG seal
All questions about QNG compliance answered at a glance
Die PROCA QNG declaration provides all actors involved in construction with a message about how a product contributes to achieving a QNG seal.
A simple, structured and BIM-compatible presentation of the required product data provides clear orientation and planning security.
With proca, you can ensure that your products meet all relevant requirements. This saves time, creates credibility and enables a transparent presentation of product properties.
This is all possible thanks to our 100% intelligent and automated service.
Label criteria relating to construction products
The following criteria set specific requirements for individual products and are therefore particularly important for construction product manufacturers:
Pollutant prevention criterion
Within these criteria, the focus is on evaluating the material health of the products, in particular with regard to emissions. For all relevant building products (except those, which are naturally emission-free), there is an overarching requirement for the quality of the building: If the product contains > 0.10% SVHC, appropriate documentation (e.g. manufacturer's declaration or REACH compliance test) is required. For further evaluation, products must comply with certain emission limits set for their product type. For example, for some products, formaldehyde emissions must be below a certain limit and for others, VOC emissions must be below a certain limit.
In EPEA's PROCA declarations, the QNG criterion for avoiding pollutants is presented with a result of “compliant” or “non-compliant.” Products that do not have requirements in this criterion are shown as “no requirement.”
Other criteria of QNG
In addition to the criteria mentioned above, there are some criteria on which construction products have an indirect effect. However, as there are no specific product quality requirements here, these criteria are not covered in the PROCA declarations.
Ecological quality criterion
This criterion aims to represent the emissions of a building over its life cycle. This ranges from the manufacturing phase through the use phase to the end of the life cycle. The individual building materials and construction products that make up the building play a relevant role here.
Economic quality criterion
This criterion consists of calculating the costs incurred over the entire life cycle of the building. Here, too, there are no specific requirements at product level, but the costs of the products are part of the overall rating.
