does anyone have any idea why discrepancies between E+ and simple steady state calculations, e.g. Q = U.A.dT, are so severe? despite it being a dynamic modelling approach you'd think that in the long term (e.g. a year) the two methods would have a reasonable harmony, instead I'm often finding 25-40% under-prediction in E+ compared to steady state for some simple buildings...
is there a recommended report for building fabric heat losses?
best regards and thanks in advance for any advice
