What is <strong>BESTEST</strong>?• Inter-model comparison method– Comparison with several other tools whichare usually better known to the validators(ESP-r, TRNSYS, BLAST, DOE2…)• Well defined cases– Cases progress systematically from theextreme simple to the relatively realistic– Specific problem detection
