[Equest-users] CFM/ton conflict issue for LEED projects

[Mustafa Herzalla]

Dear eQuest users,

 

I calculate cooling load and design air flow using eQuest software then
apply the  same design using HAP 4.3, the cooling load for the two designs
in tonnage were the same, while the design air flow in CFM was in eQuest
less than the design air flow in HAP.

For LEED projects, the proposed design should be model as the design
documents, and many designers use HAP or other design software which is
different than eQuest. and for LEED simulation we use eQuest , in this case
the CFM/ton in the baseline design is less than the CFM/ton in the proposed
design. The problem here that this case will reduce the energy savings in
fans for the proposed design. 

My question is: is it ok to make the CFM/ton for the baseline design as in
the proposed design? If NO, is there a solution to increase the design
airflow for the baseline?

 

Best,

Mustafa Herzallah
