A BESTEST validation study of the dynamic ground-coupled heat transfer model used in accurate

This paper presents the ground effective slab model used in AccuRate’s simulation engine for house energy star rating in Australia. By comparing AccuRate’s predictions with the results reported in the IEA BESTEST, it is demonstrated that for uninsulated slab-on-ground buildings, AccuRate’s ground model performs satisfactory considering the balance between calculation speed and accuracy. Potential improvement in AccuRate’s ground model has also been recommended for further development.
