|

|
| | | | | | | | | | D) | Analysis | | | | The air conditioning system of the ten story Justice Center Tower was originally serviced by two large air handler units. These two units provided the entire tower with air conditioning. One unit cooled the even floors while the other one handled the odd floors. The fan array that handles the odd floors was replaced during the fall of 2018. The original system used a single large blower wheel and alternating motor configuration which caused long down time for repairs and maintenance. The system that has already been installed for the odd floors will be the same type that will be installed for the even floors. These new systems have smaller multi-fans and direct current motor configurations which eliminates down time due to the redundancy of the fans. The system will be much more energy efficient due to the direct current motors. |
|
| | | | | | | | | | E) | Options | | | | Approve – replacement of fans will provide continued air conditioning to the even floors of the Tower. Decline – The even floors of the Tower will be without air conditioning for an unknown amount of time if the current system fails. |
