Simulator Validation Through IR Imaging

The authors have proposed a validation method for the simulation system using infrared (IR) thermography with a thermal imaging camera. The IR images will be taken to expose areas on specific rooms with potential thermal issues that may have been started after construction (for as-built modeling), like poor or inadequate insulation, air leakage, heating and plumbing issues, water damages due to leaks, condensation, mold or identification and location of other potential problems that ultimately will affect thermal comfort.

Building insulation quality becomes a pressing issue nowadays, as heating costs soar and heat leakage and thermal bridges are most common phenomena. Thermal imaging is a powerful tool for determining the energy efficiency of spaces within buildings. Here it will be used for existing construction in case that potential issues are being investigated. The simulation part will confirm the dynamic nature of the issue, while the thermal camera will capture at a certain point in time the overall problem to be addressed. The procedure can save repair time and heating costs due to early issue detection and simulation study performed afterwards. Facility maintenance and facility managers can be involved in this process with the commitment to diagnose and address the issue right after discovery.

The model validation is illustrated through a comparison process as shown schematically in the figure above. It is assumed that the CAD or BIM models are available at this stage, in order to generate the X3D thermal map of the structure in focus
