Ana,
  If you are interested in calculating the total cooling load of the 
Type56 building, you can just look at the Type56 default output called 
"QSENS" for each zone. This is the amount of energy that must be added to 
or removed from the building in order to maintain the set points that you 
specify in TRNBuild by turning on the heating and cooling types in each 
zone. If, on the other hand, you are interested in putting an absorption 
chiller in the building to meet the building's cooling demand then you are 
changing from a control mode called "energy rate control" to a control mode 
called "temperature level control." In energy rate control, the building 
model calculates how much energy was required to maintain a certain set 
temperature. In temperature level control, you have a certain amount of 
cooling capacity available in your equipment and you implement thermostats, 
ducts, fans, pipes, etc. as necessary to try and keep the building at the 
desired temperature. To use Type107 and Type56 in conjunction, you will 
need to add zone relative humidity outputs and ventilation stream inputs 
(air stream temperature, air change rate, and relative humidity) to each 
zone that you are trying to condition with the chiller. You will then need 
to implement a combination of controllers (Type2 perhaps), a fan (Type3), 
an air to water heat exchanger (Type5 can be used), and Type107 to take air 
from the building zones, cool it, and return it to the building.
Kind regards,
  david
