Minimizing the gap
“Minimizing the gap between computed and measured energy performancesusing real-time calibration” (TRIBUTE)”
Tribute proposes an innovative building key parameterselection and associated automatic calibration. The proposed presentationdescribes the developed methods for the sensitivity analysis and calibrationmethods, as well as the achieved results on test sites.
“As of today, Building Energy Performance Simulation (BEPS) analysis tends to show a large discrepancy with real energy performance. Reasons are manifold, including use of over simplified models, incorrectness of the occupancy patterns. One of the main reasons can be the inadequacy of the values of the parameters used in the simulation model, de-rived from the Building Information Model. Sensitivity analysis, relying on BEPS, allows assessing the main variables affecting the building energy performance. The study, performed in the frame of the FP7 European project Tribute (Grant Agreement 608790, extending between 2013 and 2017), aims at developing a sensitivity analysis method applied on two buildings, a public library in Torino, Italy, and a public building in la Rochelle, France. After selection of building key parameters, automatic calibration meth-ods are put in place (surface vector machine, gradient based methods, genetic algorithm based methods) for identifying the building key parameters values.
