The air-cooled chiller was essentially abandoned when the building was added to the campus chilled water system. The system used an outside DX condensing unit that was connected to an indoor evaporator/chiller unit. The outside DX condensing unit is now abandoned, and the indoor evaporator/chiller unit is now abandoned except for the duplex inline pumps and pumping package components. These duplex inline pumps are still used to circulate the chilled water piping loop for the departmental units. When the building was added to the campus chilled water system the plate-and-frame heat exchanger was added to allow the campus chilled water system to serve this chilled water loop.

These pipes enter the building on the south side of the basement Mechanical Room 10. This piping serves the chilled water cooling coils in the air handlers (located in the basement and the penthouse), chilled water cooling coils in three of the four departmental air handlers, a chilled water cooling coil in one Liebert unit for Laser Labs #2 and #3, a process chilled water system for Labs 336 and 336A, and one of the helium recovery compressors located in basement Rm. 71. There may be other lab process functions not seen on existing drawings or at time of survey. There are no chilled water pumps. The piping from the campus chilled water loop was installed around 2002 (the absorption chiller was demolished). This newer piping ties into the existing piping. A large portion of the chilled water piping in the building is 1962 original, but there also appears to have been significant new piping installed at the time of the connection to the campus chilled water loop. Some of this piping inside the building is available for future use. The cooling tower that served the absorption chiller is abandoned-in-place on the enclosed area of the roof. The age of the original 1962 piping means that this system is classified as being in poor condition. The chilled water is metered.

Each room has an electric heating coil in the supply air ductwork serving each room. These Liebert units normally serve computer server rooms, but this unit is serving a lab. This unit does not appear to have any provisions for outside air ventilation (Liebert units are not designed to condition outdoor air). This unit (with the electric duct heaters) is the only HVAC system for these two rooms. It is not supplemental cooling. This unit has a chilled water cooling coil, and an integral steam-generating humidifier. The chilled water appears to be from the building/campus chilled water loop. Overall Condition Date Installed 1/1/2009 Equipment Tag Manufacturer Model Number Comments The supply air ductwork for these labs is fabric duct, designed to provide a very even airflow distribution across this room.

15 Text6 S T E A M A N D C O N D E N S A T E P I P I N G A S S E S S M E N T D A T A Item ID Description The building is served by the campus steam system. The steam system provides heating to the building via the perimeter heating system and the steam heating coils typically located in the supply air ductwork immediately downstream of the air handling units (in the penthouse and basement room 18). There is no heating hot water other than three of the four departmental air handlers. The steam system also provides domestic hot water to the building, via a steam-to-hot water heat exchanger assembly in the basement. The steam system at one time did serve an absorption chiller in the basement, but in approximately 2002 the building was added to the campus chilled water system. The labs do not appear to use steam for any process purposes. The supply air distribution system uses a dual-duct system, so there does not appear to be any zone heating coils. Overall Condition Date Installed 1/1/1959 Material Comments The building appears to be served by a 10 medium pressure steam line. This line would have been sized to accommodate the absorption chiller in the basement. The building is also served by a 2 pumped condensate return line. These lines all enter the building at the southeast corner of basement Mechanical Room 10. The vacuum and pumped condensate receivers (both duplex) are also in Rm. 10. The vacuum condensate receiver also appears to serve the perimeter radiation (fin tube and convectors), and this receiver pumps into the pumped condensate receiver. The overall condensate return is metered. There are additional condensate receivers in basement Mechanical Room 10 (serving the AHUs in this room) and penthouse Mechanical Room 501 (serving the steam-to-hot-water heat exchanger for the departmental AHUs). Most of the steam and condensate piping and equipment in the building appear to be 1959 and 1962 original construction. Steam traps appear to be well maintained in the building and the system is not blowing steam.

21 Text6 S U P P L Y A I R D U C T W O R K A S S E S S M E N T D A T A Item ID Description There has been no complete renovation of the building supply and return air ductwork system since the building was constructed in 1959 and The two main lecture halls have had their ductwork replaced, and there have been several major lab renovations with new ductwork over the years, but there is still a significant amount of original ductwork in the building. Overall Condition Date Installed 1/1/1959 Material Comments The supply air system is a dual-duct system, tied to zone damper boxes that mix the warm and cold airstreams to achieve occupant comfort. The supply air system is constant volume (not VAV), even though there are zone-level damper systems. The original pneumatic dual-duct boxes are in very poor condition and replacement parts can no longer be obtained. Some original boxes have permanently failed and have been modified with a manual sliding metal damper on one of the two ducts, to allow some manual control of the supply air temperature. Supply air and return air from the penthouse air handlers is routed down to the occupied floors through two different building shafts. The 1959/1962 original supply and return air ductwork is internally lined. Given the age of this lining it has deteriorated and the fibers will flake off into the supply airstream and can possibly contaminate the lab spaces. In many spaces the supply air diffusers have been covered with a filter batt. See the pictures below for an example of what these filter batts look like after they are removed. Per interview with the building personnel, some of the existing ductwork mains are undersized for the renovated labs they are feeding. The entire building appears to be air conditioned. There are no window AC units in this building. The laser labs use a fabric-type supply air duct to provide a very even (draft-free) airflow distribution in the room. This fabric-type ductwork typically has a 10- to 15-year useful life. Poor Remaining Useful Life Exceeded Nominal Useful Life: 30 Years Replacement Cost $4,545,500 Galvanized steel sheet metal Replacement of the internally-lined ductwork is considered a top priority by the building personnel. Correcting the issue of original ductwork mains being undersized for some of the renovated labs, along with replacing the original dual-duct boxes, are also considered top priorities. Some original ductwork has external canvas-type insulation. This insulation or canvas jacket may possibly contain asbestos PAGE 21

23 Text A H U 1 A S S E S S M E N T D A T A Item ID Description 58.AHU1 is a built-up air handler located in the penthouse Fan Room 501. This AHU has a steam heating coil and a chilled water cooling coil. The supply air fan is integral to the unit (a double-width, double-inlet base-mounted fan), and return/exhaust fan is a floor-mounted utility-set type fan (single-width, single-inlet). Most components of this air handler appear to be 1959 original construction, but the chilled water cooling coil was apparently replaced in 2001, and the steam heating coil appears to have been replaced within the past 5-10 years, possibly at the same time as the cooling coil. Overall Condition Date Installed 1/1/1959 Equipment Tag S-1 and E-1 HP/kW This AHU feeds a dual-duct system, so the airflow is split immediately downstream of the AHU. The chilled water coil is located at the main air handler, but the steam heating coil is located downstream of the ductwork split. There is no other steam heating coil inside the AHU. The original chilled water coil was located downstream of the ductwork split, but was removed. The chilled water coil installed in 2001 is at the main air handler (a full-face coil; no bypass). Both the supply and return air fans are on variable-frequency drives (VFDs) for fan balancing and night setback. The AHU is otherwise constant volume. This AHU draws outside ventilation air through louvers in the side walls of the penthouse. This AHU also discharges relief/exhaust air through louvers in the side walls of the penthouse. This building was constructed in two phases, with the east half of the building constructed around 1959 and the west half of the building constructed around This AHU is located on the east side of the building and serves labs and offices on the east face of the 1st, 2nd, 3rd, and 4th floors.

Sanitary waste exits on the north side of the building, through one 8 cast iron sanitary line (which runs overhead in the basement and which serves the 1st, 2nd, 3rd, and 4th floors plus the penthouse) and one 4 cast iron sanitary line (which runs overhead in the basement and serves the ejector pit discharge that serves the basement). These two sanitary lines tie together at a manhole outside the building. Overall Condition Date Installed 1/1/1959 Material Existing drawings show that there is no specific distinction made between waste stack and lab stack. Waste from the labs and nearby restrooms tie together into a single stack. In other lab buildings lab stacks are kept separate from waste stacks and the lab stacks are made with Durion piping. There does appear to be a few sections of Duriorn piping in use in this building, serving waste from rooms labeled as Chemistry Labs. These short sections of Duriron piping are used only up to the point where a restroom or other branch waste line ties into the Duriron line (apparently the piping gets washed down by the other waste and Duriron was no longer considered necessary). Per building personnel, some sections of cast iron sanitary or vent piping may have been replaced with PVC as-needed due to leaks or lab reconfigurations. Any replacement of Duriron piping would has been made with acid-resistant plastic piping. There is a duplex ejector pit in the middle of basement Mechanical Room 10. All basement sanitary waste appears to tie into this ejector pit. The pumps and controls (but not the actual pit) of the ejector pit appear to have been replaced within the past 20 years.

This is a system of metered piping to allow liquid helium (used for cooling lab experiments) to be reclaimed in gaseous form and recycled for future use. The helium recovery piping for this building, as well as the helium recovery piping system that runs from Engineering Sciences Building, through the Superconductivity Center, and through the Seitz Materials Research Lab (and across the bridge/link) all tie to this building. The helium reclamation and liquefier systems are located in room this building. Overall Condition Date Installed 1/1/1988 Material The first step in helium recover is compressing the low-pressure used helium back to high pressure for storage. The compressor system is located in basement Storage Room 71 and consists of two compressors, an older model (installation date unknown) and a newer model (2012). These compressors appear to be aircooled and compress the helium to a high-pressure gaseous state for storage in either the eight tanks on the roof or some of the tanks located at grade near the northeast corner of the building. The liquefier system is also located in basement Storage Room 71. This unit compresses the gaseous helium to a liquid, which apparently is piped up to 1st floor Rm. 175 for storage in dewars. This unit uses the building chilled water system and a compact heat exchanger (with a small condenser water loop using small duplex pumps) to reject the heat that must be removed from the helium as part of the process. The recovery piping system does not have a suction pump; rather it relies on the pressure of the helium gas that is discharged into the piping to transport the gas to the Loomis Physics Lab. There is also a system of inflatable gas bags connected to the piping that allows the system to store gaseous helium at times when the reclamation system (which compresses the gaseous helium for storage in high pressure tanks) can t keep up. There is a large bag in basement Storage Room 71. There are meters that measure the amount of gaseous helium recovered. These meters are located high on the wall, typically in a storage room or a corridor, and look like natural gas meters. These meters keep track of how much helium is recovered, as projects/departments are charged for how much helium is used (not recovered). Helium supply is not piped. Liquid helium is transported into this building in dewars, from Loomis Physics Lab room 175, for use in experiments. Not all helium used in lab experiments is recovered. The system is ultimately replenished by the tanks of high-pressure helium located on a trailer outside the northeast corner of the building. Several different piping materials appear to be in use for this system: copper (sweat), PVC, and braided-jacket flex hoses.
