Description of European Prototype Tool for Evaluation of Building Performance and the national tools

The aim of the project Building EQ "Tools and methods for linking EPBD and continuous commissioning) is to support the introduction of both certification according to the Energy Performance of Buildings Directive (Directive 2002/91/EC) and continuous commissioning, which is seen as a prerequisite for an energy efficient long term operation of buildings. Both EPBD and continuous commissioning are relatively new approaches that are still under development. The current state of the implementations of the EPBD and the diversity between countries makes a direct coupling between EPBD and commissioning on a common basis difficult. In the framework of Building EQ project , Guidelines for the Evaluation of Building Performance have been developed. The Guidelines describe a 4-step procedure for the cost effective performance analysis following a general top-down approach that tries to combine the outcomes of the certification process according to EPBD with continuous commissioning. The idea of this top-down approach is to put effort in form of measurements and analysis only where and when necessary. The transition from one step to the next should only be performed if certain criteria are fulfilled. The objective of WP5 of the Building EQ project (Development of assessment-tools based on EPBD data) is to develop a set of tools that can support this 4-step procedure. The development has two lines: one is the enhancement of two other tools (Granlund and ennovatis), the second line is a tool on European level, which will have a basic functionality. As the two existing tools are more sophisticated but partially specific to their respective country the main purpose is to use them as a benchmark for the development of the European tool. This report gives an overview over the features of the European tool and a description of the two other tools.
