Existing drawings do not show the installation of the service provided by the campus loop, but the chilled water service appears to enter on the north side of the north building. A branch from this service runs through the tunnel between RAL south and the Noyes Lab to serve the Noyes Lab. Overall Condition Date Installed 1/1/1993 Material Not all AHUs in the north building use the campus chilled water loop. AHU-2, AHU-16, and AHU-17 are heating-only units. AHU-6, AHU-25, AHU-405, and possibly AHU-18 use the chilled water loop served by the two roof-mounted air-cooled chillers. Generally all other air handlers in the building use campus chilled water for cooling. The chilled water system appears to be sized to eventually accommodate the entire building. Campus chilled water also serves two Computer Room Air-Conditioning (CRAC) units on the third floor, serving a CITES room (6.5 gpm) and an X-ray room (5.4 gpm). The campus chilled water also serves X-ray equipment on the third floor (3.2 gpm). The campus chilled water service replaced an earlier local chilled water service that originated in the Chemical and Life Sciences Lab building (which replaced a small chiller in the RAL south building penthouse). Thus some of the piping used by the campus chilled water system predates the campus chilled water service tiein to this building (approximately 2010). The chiller located at ground level on the north side of the building appears to be abandoned (disconnect appears to be in the off position), or possibly it is intended to serve as a backup system. The chiller appears to have been installed in the mid 1990 s, and is in fair condition. The chilled water is metered.

This loop uses the two air-cooled chillers on the roof (WCU-1 and WCU-2) in a primary-secondary arrangement. Each chiller has a single primary pump, and the secondary chilled water loop to the air handlers appears to use one pump to serve AHU-6 in the basement and one pump to serve the other air handlers. The pumping packages are located in the penthouse. This loop uses a 30% ethylene glycol solution. The other AHUs in the building that have a cooling coil use chilled water from the campus chilled water system.

Per Andy from Steam Distribution, the high pressure steam is only used in autoclaves for sterilizing lab equipment. Steam is otherwise not used by the labs (no steam to fume hoods). Overall Condition Date Installed 1/1/1950 Material Comments The perimeter of the building is largely heated by steam radiators or fin tube, with vacuum condensate return. The renovated third and fourth floor labs use hot water perimeter heat, and the existing drawings for these projects indicate that the hot water systems are designed to be expanded to cover the entire building floor. Most (but not all) AHUs in the building use a steam heating coil. Some AHUs (but not all) use steam zone heating coils. See the descriptions for each AHU. Where hot water is used for heating (in an AHU coil, in a VAV reheat coil, in a zone heating coil, or in perimeter fin tube), the water is heated by a steam-to-hot water heat exchanger. Domestic hot water is heated by a steam-to-hot water heat exchanger assembly. Three duplex condensate receivers are located in the middle of basement Mechanical Room 8. One receiver is a vacuum-type receiver. One additional duplex condensate receiver is located nearby in a pit. These condensate receivers pump into a 4 line that runs (overhead in the basement) to exit the building at the west end of the basement mechanical room, near where the steam enters the building. Condensate is metered. Per the list of building meters, at one manual meter is still in use in this building.

The steam service enters the building at the southernmost room of the basement mechanical room. There is a 3 high pressure and 12 low pressure service to the building. There is a 4 pumped condensate return. The regularly in-service air handling units have been converted to heating hot water. The majority of the steam use is through hot water convertors.

These hose valve cabinets (with hoses now removed) are still in service. These older Hose valve cabinets are typically located in the north, west and east corridors, and feature hose valve connections on each floor (except for the basement). The north corridor and east corridor risers also serve the penthouse. The basement does not appear to have any standpipe connections. This older standpipe system appears to have two valves, a 1-1/2 valve connection (presumably for use with the hose in the cabinet) and a 2-1/2 valve connection for fire department use. Overall Condition Date Installed 1/1/1950 Material At a later date a fire protection riser was added to the East stairwell. This riser serves the sprinklers located in the north building, but also has a hose valve connection in the east stairwell on the ground floor, 1st floor, and 2nd floor. The fire protection piping system (standpipes and sprinklers) in the north building appears to be served by a 6 connection that enters from the south building (at the east corridor) and appears to routed from the Chem Life building. This 6 connection has a fire pump that appears to be located in the Chem Life building. The North building has a single siamese fire department connection, located on the north side of the building. Due to the age of some of the piping in this system it is considered to be in poor condition.
