>The energy balance on a zone is given by: >BAL_ENERGY = -DQAIRdt + QHEAT - QCOOL + QINF + QVENT + QCOUP + QTRANS + >QGINT + QWGAIN + QSOLGAIN >BAL_ENERGY should be always 0. This (the energy balance) should be included in the coming TRNSYS manual. Although TYPE56 outputs lists all types of energy, it is often hard to check this balance. E. Halawa
