when I run simulation in design builder with set point temperatures of 22 degree centigrade of heating and 24 degree centigrade of cooling I got -5000 which is negative of total cooling load of building and again changing setpoint temperatures to 24 of heating and 26 of cooling i got -3000 which is again negative but value has been changed and i didn't understand weather cooling load reduced or increased or energy consumption increased or decreased. can u give some reason and justification to my question. thank you in advance
