Developments in environmental performance for existing buildings
The development of Assessment Methods for renovation, transformation, and maintenance represents a significant step in expanding the environmental performance system to existing buildings. To ensure these methods can be effectively applied in practice, several follow-up steps will be taken in the coming period.
On this page, you can read about the current developments and what they mean for applying environmental performance in interventions on existing buildings.
The Assessment Methods for renovation, transformation, and maintenance will be further developed and applied in practice in the coming period. This involves creating new Category 3 data for maintenance, expanding usage scenarios with practical explanations, implementing the methods in calculation tools, and continuing to refine them based on practical experience.
Introduction
With the development of the Assessment Methods, an important foundation has been established for the environmental performance framework for existing buildings. To ensure proper application of these methods in practice, several follow-up steps will be taken in the coming period. These developments are outlined below.
1. Category 3 data for maintenance
A project will be initiated to develop Category 3 data specifically for maintenance. These data can be used when calculating the environmental performance of maintenance activities in accordance with the Assessment Method Environmental Performance Maintenance (MPO).
Further communication will follow once more information becomes available regarding the development and publication of Category 3 data for maintenance.
2. Expansion of practical examples and development of guidance
Based on a range of practical examples, this page explains when each method should be applied. This set of scenarios will be further expanded and published on the website once available.
In addition, we are developing practical guidance for both methods. These explanations provide further clarification of key concepts and include example calculations to support the application of the methods in practice.

3. Implementation and validation of calculation rules in calculation tools
Following the publication of both Assessment Methods, a validation round will be organised for tool owners who wish to implement the calculation methods for existing buildings. Validation is carried out in accordance with the Validation Protocol. “Validated” indicates that calculation tools have correctly implemented the calculation rules from the method, ensuring that users obtain the same results when performing identical calculations.
The total lead time for implementing the calculation rules in the tools and validating them by Stichting NMD is six months. After validation and release of the methods in the software of tool owners, the market can start applying them in practice.
4. Further development of the Assessment Methods for existing buildings
- After publication of the MPO Assessment Method v0.9, practical experience will be gained through application in real projects. As long as no validated calculation tools are available for MPO calculations, a temporary (non-validated) MPO calculation tool will be made available via the RVO website. Based on the results of these pilots and the experience gained in practice, the method will be further optimised towards version 1.0.
- Following implementation in practice, the Assessment Method Renovation & Transformation will be evaluated. Based on this evaluation, improvements and optimisations can be made where necessary.
- The methods will be further expanded, including exploring how energy-related environmental impacts (modules B6 and D2) can be incorporated. In addition, work is underway to align with the wlc-gwp method.
