Experimental facilities for assessing energy flexibility in buildings
Public seminar Annex 67 - Energy Flexible Buildings Annex 67 4th April 2019, Aalborg University
Jaume Salom
Motivation
• Development of Energy Flexibilitystrategies (usually developed bysimulation) need to be validated underdynamic working conditions
• Laboratories for Energy Flexibility offersto researchers and industry thepossibility to test the performance ofproposed systems in controlledenvironments prior to theirimplementation in real buildingsand/or field tests.
Semi-virtual method: Operation of real equipment according to the behaviour of a building/system computer model to emulate dynamic woking conditions in Hardware-in-the-loop
