The new European standard EN 15804+A2 regulating EPDs for construction products will have particular impacts on the impact assessment stage; therefore, it will be impossible to compare EPD results with those according to the previous version EN 15804+A1. In order to offer all declaration owners an efficient and effective solution for the long transition period of 3 years, IBU has developed an attractive pricing model; it fully passes on the considerable synergies from a parallel EPD calculation using both the old and new standards. This allows producers of production products to always satisfy all requests for EPDs.

The new standard EN 15804+A2 is expected for fall 2019 and will bring a number of fundamental changes for EPDs of construction products. Probably the most visible of these changes is the mandatory consideration of modules C (end of life) and D (benefits and loads beyond the system boundary) which are still optional in EN 15804+A1. In addition, new characterization factors and sometimes even completely new models will be used for the so-called impact assessment, i.e. the aggregation of all the data about emissions and resource use into relatively few indicators. The latter is the reason why results from an EPD following the new standard can in no way be compared to those obtained following the old standard.

Considering the exceptionally long transition period of 3 years this creates a dilemma for all producers that want to prepare a new EPD or update an existing one: If they go for the new standard their EPD will have limited value in the beginning as there will not be enough comparable datasets for the calculation of a complete life-cycle assessment of a building. If, however, they publish an EPD following the old standard there is a serious risk that this EPD will soon become obsolete. Adding to the complexity is that for the time being there are no robust estimates as to when there will be a critical mass of EPDs following A2 – from that moment onwards this will be the standard to select.

The perfect solution for both producers and users would be to publish two EPDs in the transition period – one EPD following the old, one following the new standard. Therefore, IBU offers an attractive pricing model: for a small additional fee it allows its members to get a verification of EPDs following both EN 15804+A1 and EN 15804+A2. This solution enables owners of EPDs to satisfy all requests from clients and planners.
