Frequently asked questions Assessment method
The Environmental Performance Assessment Method (in short, Assessment method) is a uniform measuring method for calculating the environmental performance of structures in an unambiguous, verifiable and reproducible manner. It thus creates a level playing field for all parties involved. The environmental performance of various structures can be compared, with the aim of reducing the ultimate environmental impact of a structure. In the Netherlands, EN 15804 is the foundation of the Assessment Method.
Construction companies calculate the environmental performance of a construction with the Environmental Performance Assessment Method. They use it to calculate the environmental impact of material use. The outcome of this calculation is expressed in 1 number (Environmental Performance of Buildings - EPB (Dutch: MPG) for B&U, Environmental Cost Indicator - ECI (Cutch: MKI) for GWW). This allows developers to see which building components cause the most (negative) impact on the environment.
The Stichting Nationale Milieudatabase (formerly Stichting Bouwkwaliteit) manages the Assessment method.
