[TRNSYS-users] Cooling Demand Estimation

Htet,

   It is not really possible to diagnose without seeing the project and 
without knowing a little more about what you expected to see. If the 
cooling demand is a lot lower than you were expecting then one very 
common reason is forgetting to set a value for the temperature of the 
floor/soil boundary and instead leaving it set to its default of 0C, 
which causes the building to stay a lot colder throughout the year than 
is reasonable.

kind regards,

  David
