Dear all Just for information I finally get quite good results by adjusting the thermal characteristic of the concrete slab above the active layer. I previously used standard values from BESTEST (http://www.nrel.gov/docs/legosti/old/6231.pdf) which are quite extreme. When using more conventional values for reinforced concrete I get emitted power to the zone really close from manufacturer calculations (gap < 2%). -- Antoine Gautier antoine.gautier@solamen.fr |
