ARTICLE 8 (n) Project: Police Station Ventilation System CPA Category: Historic Resources Amount Requested: $31,700 Amount Recommended: $31,700 CPC Vote: (6-3) Project Description: This project is requesting funds to replace the Police Station lower level ventilation unit with a higher rated fan and motor to achieve required ventilation. The existing unit is undersized and cannot deliver design airflows. As a result, the lower level, including holding cells, is not being adequately ventilated, resulting in insufficient fresh air and odor control. In addition, air conditioning will be installed to control relative humidity levels in the summer months. This project will also include an update of the Massachusetts Historical Commission Inventory Form "B". Project Goals and Objectives: Police Station audits have reported that the ventilation of the holding cells is inadequate. The goal of the project is to achieve design flow rates. Project Benefit: The existing unit cannot deliver required airflow due to the pressure drop of the installed ductwork. The new fan and motor will be rated to operate with the installed ductwork and achieve design airflow. The existing system was installed in 1994.; during the past fifteen years, the failure of the system to adequately vent the cell-block has been an impediment to operations and an unhealthy condition for detainees. This lack of air flow must be corrected. Outside air is heated when necessary, but not cooled. During summer months, lack of air conditioning allows saturated air to condense on cool, sub grade surfaces. Funding Request: The project requests $31,700 in CPA funds to be used to implement extraordinary repairs to the Police Station's lower level HVAC and to update the Massachusetts Historical Commission Inventory Form `B". 19
