Hello. Here is the information you requested in regards to Cognex located at
15865 SW 74
1. Enclosed is the Non - Residential Energy Code forms.
2. AC -6 is 2400CFM. It provides for 480CFM of outside air. Manufacturing
occupancy load is 200 square feet per person. There is 1400 square feet
being serviced by AC -6. 1400 divided by 200 is seven people. At 20CFM per
person the outside air requirement is 140CFM. I have specified on the plans
the grill placement and CFM capability.
3. The economizer has a damper which closes upon an unoccupied signal from
the thermostat.
Reference mechanical permit #2000 - 00340.
Sincerely,
Darren W. Urton
