Specifications include, but are not limited to: Design services to complete renovations to the outdoor air systems in both Turner and Schneider Hall. These buildings are dormitories and consist primarily of dorm suites with some common areas and mechanical spaced in the basements and attics. There are six outdoor air systems which currently condition the air with an enthalpy air to air plate heat exchangers, using the toilet exhaust, and staged electric heating coils for each of the outdoor air fans. This provides minimal condoning of the outdoor air and heating to maintain a minimum 55°F in the winter, and maximum 86°F in the summer. This project would add either chilled water or direct expansion (DX) cooling coils to enable dehumidification of the outdoor air prior to distribution to the building. An analysis of the existing chilled water system, which serves both buildings, will need to be completed to determine if enough capacity exists and if a pathway existing to get the required flow to the attics. This analysis will help in determining whether to use chilled water or DX for cooling. If DX coils are used, the condensing units would be located in the same attic space and would require modifications to controls for the existing attic ventilation fans to ensure heat rejected is removed from the attic space. Review of the existing structure will be needed to review the existing attic structure to determine if any modifications will be needed to support new cooling coils and possible equipment if DX is used
