Hello Ahlem,It is because of your schedules named as SETOFF in building model. Since you created weakly schedule, first day of first year will be Monday. First day of second year will be Tuesday. So heating schedule changes a bit every year. You can see the pattern repeating over every seven years if you do simulation for longer period. To avoid this problem, create yearly schedule. Hope this helps you.RegardsPrasanth SubramaniOn Fri, Oct 26, 2018 at 8:40 AM berkane ahlem via TRNSYS-users <trnsys-users@lists.onebuilding.org > wrote:hello sirs,______________________________

increasing in the third year (-6804.004kwh) and decreasing in the
forth year (-6793.2kwh) while it should decrease every year .I’m
