International Energy Agency, EBC Annex 58: “Reliable building energy performance characterisation based on full scale dynamic measurements” - Report of Subtask 1B: Overview of methods to analyse dynamic data

 

This report is one of the deliverables of the International Energy Agency Energy in Buildings and Communities programme (IEA EBC) Annex 58 “Reliable building energy performance characterisation based on full scale dynamic measurements”. The document was released by Subtask 1 of the annex, aiming to give an overview and evaluation of previous and ongoing in situ test activities based on a literature review and existing reports. An inventory was made of full scale test facilities for the evaluation of energy performances of building components and systems, available at different institutes all over the world. Common methods were described to analyse dynamic data, with their advantages and drawbacks.

 

The present report aims to give an overview of existing data analysis methods, ranging from averaging and regression methods to dynamic approaches based on system identification techniques. These methods are discussed in relation to their application in following in situ measurements:

 

  • measurement of thermal transmittance of building components based on heat flux meters;
  • measurement of thermal and solar transmittance of building components tested in outdoor calorimetric test cells;
  • measurement of heat transfer coefficient and solar aperture of whole buildings based on co-heating or transient heating tests;
  • characterisation of the energy performance of whole buildings based on energy use monitoring.
