With all maintenance and repairs completed, and verification of test results on the seventh floor, the project moved toward completion for the rest of the building.
One last snag appeared. In order to maintain adequate static pressure and airflow for the Pharmacy, minimum total airflow could not be reduced to the design minimum. Additional boxes were identified to maintain minimum flow that allowed the Pharmacy to be properly supported.
The net result of changes made was a reduction of unoccupied cfm to approximately 50,000 cfm, a 50% decrease in unoccupied airflow, which translates to an EUI reduction of nearly 22 kBtu/ft2.
With this stage of the project (ECM-1) complete it was time to move on to redefining occupied airflow. This aspect is covered in Part 2.
