These pipes enter the building on the east side of the basement Mechanical Room 30. This piping serves the chilled water cooling coils in the air handlers (located in the penthouse). There are no chilled water pumps. From the basement mechanical room there is also a 6 chilled water supply and return branch line routed to the Superconductivity Center to serve that building. The branch pipes exit the building at the northwest corner of basement Mechanical Room 30. Overall Condition Date Installed 1/1/1966 Material Comments The piping from the campus chilled water loop was installed around This newer piping ties into the existing piping. Most of the chilled water piping in the building is 1964 original. The branch piping to the Superconductivity Center was installed around The chilled water is metered. Poor Remaining Useful Life Exceeded Nominal Useful Life: 30 Years Steel pipe Replacement Cost $261,700 The older canvas-style insulation on the 1964 original piping may possibly contain asbestos PAGE 5

Reworked chilled water piping (black insulation) ties to the 1964 original chilled water piping (grey insulation) in basement Mechanical Room 30. Branch chilled water piping to Superconductivity Center and taps for the since-removed absorption chillers in basement Mechanical Room 30. Some of the taps are also remnants of the phased plan to convert this building and adjoining buildings to the campus chilled water system PAGE 6

7 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 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 in the air handling units (in the penthouse). There is no heating hot water, except for the bridge link between this building and the Loomis Physics lab (the bridge was constructed as part of the Materials Research Lab building and is served from the building). 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 absorption chillers 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 1/1/1966 Material Comments The building appears to be served by a 16 medium pressure steam line. This line would have been sized to accommodate the absorption chillers in the basement. The building is also served by a 4 pumped condensate and a 4 vacuum condensate line. These lines all enter the building at the northeast corner of basement Mechanical Room 30. The vacuum and pumped condensate receivers (both duplex) are also in this area of Rm. 30. The incoming 4 vacuum condensate line appears to be tied to the inlet side of the vacuum condensate receiver, which presumably pumps into the pumped condensate receiver. The vacuum condensate receiver also appears to serve the perimeter radiation (fin tube and convectors). The overall condensate return is metered. Most of the steam and condensate piping and equipment in the building appear to be 1964 original construction. Steam traps appear to be well maintained in the building and the system is not blowing steam. Poor Remaining Useful Life Exceeded Nominal Useful Life: 30 Years Size/Capacity Steel piping Replacement Cost $1,490, medium pressure steam supply, 4 vacuum condensate return, 4 pumped condensate return The older canvas style insulation seen on the steam and condensate return piping may possibly contain asbestos PAGE 7

9 Text6 H E A T I N G H O T W A T E R A S S E S S M E N T D A T A Item ID There is a small steam-to-hot water heat exchanger system located in the Penthouse. This heat exchanger produces hot water for heating the bridge link between the Materials Research Lab and the Loomis Physics Lab. The bridge link has hot water fin tube heating and a radiant floor in the portion of the 1st floor that is exposed above Boneyard Creek. This radiant floor is abandoned. There is a base-mounted simplex pump (P-7) that serves the fin tube. The separate pump (P-8) for the radiant floor is abandoned. The bridge link supply air system appears to use a dual duct system, so there does not appear to be hot water reheat coils in use.

12 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 There has been no major renovation of the building supply and return air ductwork system since the building was constructed in There have been piecemeal renovations when labs have been reconfigured, but generally the ductwork in this building is 1964 original construction. Overall Condition Date Installed 1/1/1966 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. Supply air and return air is routed from the air handlers in the Penthouse down to the occupied floors through four different building shafts. Supply ductwork is round or rectangular, and return air ductwork is typically rectangular. The rectangular supply and return air ductwork is said to be 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. Some of the supply air distribution ducts to labs that require a clean airflow have added HEPA filters with booster fans. In other labs the supply air diffusers have been covered with a filter batt. The entire building appears to be air conditioned. There are no window AC units in this building. Poor Remaining Useful Life Exceeded Nominal Useful Life: 30 Years Replacement Cost $3,189,600 Galvanized steel sheet metal Given the age of the dual-duct boxes, spare parts are apparently no longer available for these boxes. The original canvas-type insulation seen on the ductwork may possibly contain asbestos PAGE 12

The supply air fan and return/exhaust fan are floor-mounted utility-set type fans. Most components of this air handler appear to be 1964 original construction. Overall Condition Date Installed 1/1/1966 Equipment Tag 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. The chilled water coil has been replaced since The original chilled water coil was located downstream of the ductwork split, opposite of the steam heating coil. This abandoned coil is still located in the ductwork. The newer chilled water coil is at the main air handler. Both the supply and return air fans are on variable-frequency drives (VFDs) for fan balancing and possible night setback. The AHU is otherwise constant volume. This AHU serves the northeast portions of all four floors plus the basement. Like the connected ductwork, this AHU appears to have an acoustic lining on the inside. This lining has deteriorated and is flaking off into the airstream, creating air quality problems in the laboratories.

The exhaust fan is a belt-driven inline fan, located at the vertical duct riser in the penthouse. Per existing drawings this is the only toilet exhaust fan in the building. The fan and its flex connections appear to have been reasonably well maintained. Overall Condition Date Installed 1/1/1966 Equipment Tag Fan E-20 HP/kW 1 Comments This exhaust fan discharges through the louvered penthouse (known as the chicken coop ) on the roof. Nearly all lab exhaust fans also discharge through this louvered penthouse. This louvered penthouse, due to its low elevation above the roof, reportedly does not allow the exhaust air discharges to disperse thoroughly enough into the prevailing winds. The result is that this building has some issues with exhaust air discharge being sucked back in through the outside air intake louvers at the sides of the penthouse. Poor Remaining Useful Life Exceeded Nominal Useful Life: 30 Years Voltage Replacement Cost $6, V / 3 phase The need to rework the lab exhaust to prevent contamination of the ventilation air intake was also listed as one of the biggest priorities for this building by the director for this facility PAGE 32

There appears to be a fan for each individual hood. These fans appear to operate as constant volume. There is no provision for heat recovery from any lab exhaust system. The lab exhaust fans are generally inline fans located in the penthouse, although there are four roof-mounted fans. Some inline fans in the penthouse are located in the vertical rises as they come out of the building shafts, and some are located in horizontal duct runs. Most of the penthouse fans appear to be 1964 original construction, but have been maintained reasonably well. Overall Condition Date Installed 1/1/1966 Comments The exhaust fans in the penthouse discharge through the louvered penthouse assembly (known as the chicken coop ) on the roof. This louvered penthouse assembly, due to its low elevation above the roof, reportedly does not allow the exhaust air discharges to disperse thoroughly enough into the prevailing winds. The result is that this building has some issues with exhaust air discharge being sucked back into the building through the outside air intake louvers at the sides of the building penthouse. Possibly the exhaust fans on the roof (which are dilution-type with extended-height discharge) are serving hoods with especially hazardous or odorous fumes. One of the newer roof-mounted exhaust fans on the roof makes use of one of the 12 condenser water pipes that runs from the lower floors up to the penthouse roof area. This condenser water pipe serves as part of the exhaust ductwork system for a fume hood in a renovated lab. These condenser water pipes were otherwise abandoned when the building was added to the campus chilled water system around Poor Remaining Useful Life Exceeded Nominal Useful Life: 30 Years Replacement Cost $902,300 The need for a heat recovery system for the lab exhaust was listed as one of the biggest priorities for this building by the director for this facility. The need to rework the lab exhaust to prevent contamination of the ventilation air intake was also listed as one of the biggest priorities for this building by the director for this facility PAGE 34

This duplex air compressor is a newer installation and is in good condition. The lab compressed air piping systems for both the Superconductivity Center and the Materials Research Lab are also tied into the compressed air system for the HVAC controls. So essentially there are four separate air compressors that back up the HVAC control system. This is because the pneumatic thermostats of the HVAC controls system will fail high, where a failure of the HVAC controls compressed air system will cause the building(s) to overheat, ultimately tripping the heat detectors of the fire alarm system and bringing the fire department to the building.

Sanitary waste exits on the north side of the building, through two 6 cast iron pipes and one 4 cast iron pipe. With the construction of the Superconductivity Center building around 1993, one of these 6 sanitary lines now ties into a sanitary line in the basement mechanical room of the Superconductivity Center. Sanitary risers appear to be grouped into soil stacks and lab waste stacks. The lab waste stacks and all downstream horizontal runs are Duriron, which is apparently in poor condition after many years of accepting lab waste. Any portions of lab waste piping that have been replaced (on an as-needed basis due to leaks) have been replaced with plastic acid-resistant piping.

Piping from the Engineering Sciences Building extends through the Superconductivity Center and through the Materials Research Lab to reach the Loomis Physics Lab. Overall Condition Date Installed 1/1/1988 Material The 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 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 the Loomis Physics Lab, for use in experiments. Several different piping materials appear to be in use for this system: copper (sweat), PVC, and braided-jacket flex hoses. The exact installation date of this piping system is unclear.
