TestingΒΆ

Kiva has been tested against the International Energy Agency Building Energy Simulation Test (IEA BESTEST) in-depth diagnostic cases for ground coupled heat transfer related to slab-on-grade construction [2]. The results match very closely with the analytical truth standard and the verified numerical truth standards:
