I want to calculate the required heat in order to maintain the temperature in the zones in this range, so after running a simulation I look at the " building:all zones:supplied energy:heating (W)". However I notice something weird with these values. I am always getting a sequence of large-small values. Am I doing something wrong? Is there something that I am missing? An example is given below taken from the .csv file containing the results.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><table class=MsoNormalTable border=0 cellspacing=0 cellpadding=0 width=332
