In order to accurately evaluate the performance gap, it is essential that the testing methods used in research are robust and reliable. With this in mind, Subtask 2 of Annex 58 of the International Energy Agency ‘Energy in Buildings and Communities’ programme has produced a decision tree to support both researchers and industry professionals, with the overall aim of ensuring accurate testing and data handling methods are used. The Decision Tree follows a logical format, determining the context and limitations of the research before suggesting documents to support accurate testing; for example international standards and peer reviewed journals.

The full Decision Tree is presented using Xmind, which is a free mind-mapping tool that can be downloaded from www.xmind.net. Supporting the Decision Tree, there is also a Readme document which details the function and use of the Decision Tree. Both documents can be found on the DYNASTEE website by following this link.
