I. EXECUTIVE SUMMARY

Purpose

The purpose of this study is to provide a high level HVAC conditions assessment for both Brown and Drake Laboratories to provide a roadmap for the University of Delaware Facilities and Chemistry and Biochemistry Department to use to manage the use of these systems. The study makes recommendations for long term facilities upgrades and provides guidance on the limitations and use of the existing systems and infrastructure for future changes and renovations. Rough order of magnitude (ROM) costs have been provided where applicable for capital funding requests and facilities planning purposes for future renovations.

Modern chemistry laboratory facilities are always constantly challenged by the need to keep up with new and improved scientific equipment, with changes in teaching protocols and with the constant inflow of new research projects. This study is intended to provide a masterplan for the University to use to ensure both Brown and Drake Laboratories continue to support the teaching and research needs of the Chemistry and Biochemistry Departments for many years to come, despite these challenges.

Summary

The HVAC systems associated with Brown and Drake Hall are in generally good condition and have been provided with upgrades over the life of the buildings and over the life of the HVAC systems that are present. The primary steam and chilled water services (which come from the Campus Boiler House and Campus Chilled Water Plant) appear adequate for current and future loads. Expansion or upgrades to these primary services is not needed unless significant changes in programmatic requirements or internal loads is expected.

The primary air-side equipment is in good condition and laboratory upgrades or renovations can be performed pretty much anywhere within the two buildings, with guidance needed on how and specifically where they are most easily executed. The major air-side equipment is in good condition within the buildings with the exception of AHU-1 serving Drake and AHU-1 and AHU-2 in the Brown South Wing. These units are in need of replacement due to age or lack of adequate capacity, and it is recommended that a long term capital plan be put in place to replace them. A more detailed explanation of the general capacities and limitations of and recommendations for the air-side systems is provided by building and by area below as each are served by distinctly different equipment and systems.

Drake

With the upgrades to the laboratory supply and exhaust systems completed in 2013 within Drake, Drake is an ideal candidate for cost effective laboratory renovations in the future. This is because each laboratory can now be isolated at the supply and exhaust air valves within the laboratory without impacting other spaces to perform simple modifications.

The limitations within Drake, however, are its air handling units. The existing air handling unit (AHU-1) in the basement is old, although it has been upgraded, and it is running very near its maximum capacity. Because many of the spaces being served by AHU-1 are currently underutilized it still has extra capacity to handle some



upgrades to probably one or two laboratories within Drake to a higher utilization (based on Building Automation System readouts of operating conditions); however, it does not have enough capacity to serve all the existing older laboratories being renovated and taken to maximum utilization. It is recommended long term to either replace AHU-1 in-place with a custom unit that has slightly more capacity, to add a new air handling unit(s) indoors or outdoors in the courtyard between Brown and Drake, or to move spaces off AHU-1 and to AHU-2 in order to use extra capacity available from AHU-2 and maximize capacity of AHU-1. The new air handling unit AHU-2 that was installed on the roof of Drake in 2013 to serve just Laboratories 112, 318 and 320 has approximately 11,000 CFM additional air that can be utilized to serve future laboratories that are now being served by AHU-1.

Regardless of the options that the University decides to move forward with we recommend at a minimum they should prioritize the third option, and primarily for spaces on the third floor still served by AHU-1. Removing these third floor laboratories from AHU-1 and adding them to AHU-2 is a low cost way to provide additional capacity for AHU-1 with really only the addition of ductwork on the roof down to connections to the existing supply air valves. Approximately 5,000 sf of standard chemistry teaching laboratories or standard chemistry research laboratories or one additional 1200 sf organic chemistry teaching laboratory could be added to AHU-2 on the third floor with the additional capacity that is available. The other options of adding or modifying air handling units that could be executed within Drake were studied in greater detail by Jacobs in the Drake Hall Lab Renovation Feasibility Study dated October 10, 2014. The long term solution, however, will most likely need to be a combination of these options.

One of the additional challenges within Drake is the exhaust ductwork risers. The supply air system has fewer larger ductwork risers that can take advantage of diversity and as such have additional capacity available, however, the exhaust system was designed with multiple smaller ductwork risers which limits the ability to expand and take advantage of diversity on the floors. This means that any major increase in airflow required at the individual laboratory spaces may require new ductwork being run up through the building to the roof exhaust fans.

For laboratories where the supply airflow is load driven and not fume hood makeup air driven, another option could be considered. That option is to use a hybrid system, utilizing the primary AHU system to provide initial cooling capacity to the laboratories and to provide makeup air for fume hoods, but not provide all the sensible cooling that is required. The additional sensible cooling in each lab could then be handled by local fan coil units, radiant cooling ceiling panels or other local sensible cooling equipment. Keeping the supply airflow at the EH&S minimum criteria of 10 air changes per hour provides approximately 1.7 CFM/sf and can be handled with the existing AHU equipment. As indicated in the analysis section of the report, a standard chemistry teaching laboratory or chemistry research laboratory would normally require 2.1-2.2 CFM/sf to satisfy the internal heat loads. The additional cooling required beyond the 1.7 CFM/sf supplied by the existing AHU could be handled with local hydronic cooling equipment directly off the chilled water system. This approach, however, will not work for the organic chemistry teaching laboratories because they are fume hood makeup air driven, and as such they need more air from the central AHU system.



Brown South Wing

The Brown South Wing HVAC systems are probably as a whole the most in need of major upgrade. The air handling units and general laboratory exhaust fans, although they provide adequate capacity to the spaces being served, they are at the end of their useful life and in need of replacement. The general supply and exhaust air ductwork systems themselves are also still operating in a constant volume reheat mode, which is not energy efficient and does not allow for diversity in the system. This lack of diversity means you can’t fully take advantage of the full CFM capacity of the AHU capacity the way a full VAV (variable air volume) system does.

It is recommended that before any major laboratory renovations are undertaken in the Brown South Wing that a full HVAC system upgrade be performed, which would include replacing air handling units AHU-1 & AHU-2, replacing exhaust fans EF-1, 2 & 3, replacing pumps and heat exchangers in the penthouse and converting the ductwork distribution system to a VAV system by installing supply and exhaust air valves (similar to what was done in Drake). This would also solve an issue that the Building Automation System (BAS) shop has, which is that they can’t monitor the older Staefa control system through their main BAS control panel. When these upgrades are performed all new controls should be installed and integrated with the campus BAS system so the entire Brown Building could be monitored and controlled through the single BAS system.

One of the additional challenges with Brown South Wing is the ductwork risers, both supply and exhaust. The system was designed with multiple smaller ductwork risers which limits the ability to expand and take advantage of diversity on the floors. This will require that any upgrade or renovation provide a careful review of the ductwork capacities on the floor and within the area being renovated before moving forward with the design.

Brown North Wing

The area within Drake and Brown that has the greatest potential for simple and cost effective renovations or laboratory upgrades at an individual laboratory or floor level is the Brown North Wing. This area has new primary air handling units and central laboratory exhaust fans with additional capacity for future loads. The area is served by this equipment has been provided with large primary vertical supply and exhaust risers, which makes upgrades on the floors easier to accomplish when loads increase because they can take advantage of the diversity within the system. The existence of larger equipment loads in the areas within Brown served by these units helps provide this overall greater system diversity.

Brown West Wing

In general the HVAC systems within the Brown West Wing serve classrooms, auditorium and offices. Very few laboratory spaces exist within Brown West; however, those that do have been provided with upgraded laboratory supply/exhaust air valves and they are served by new air handling equipment in the penthouse of Brown West. The one unique aspect of the laboratories in Brown West is that all the laboratory exhaust from Brown West is routed through Brown North to be exhausted by the combined general exhaust fans on the roof of the courtyard infill between the Brown North Wing and Brown South Wing. There are some smaller dedicated laboratory exhaust systems within Brown West; however, they are smaller and aren’t expandable. The other challenge with the laboratory systems serving Brown West are that they were also designed with multiple smaller ductwork



risers which limits their ability to expand and take advantage of diversity on the floors. This again will require that for any upgrade or renovation planned a careful review be performed of the ductwork capacities on the floor and within the area being renovated before moving forward with the design.






II. EXISTING HVAC SYSTEMS Brown – Existing HVAC Systems

The original Brown building was constructed in 1938 as the Chemical Engineering Building. The South Wing addition was added as the Chemical Engineering Annex in approximately 1950. The North Wing addition was added in approximately 1960. The facility has continued to function as a teaching and research laboratory facility for Chemistry and Biochemistry and the older portion of Brown contains a major auditorium as well as administrative offices and general purpose classrooms. The North and South Wings contain primarily teaching and research laboratories. Major renovations happened throughout the three wings of the building thru the 1970’s and 1980’s. In the 1990s a major renovation was undertaken within the South Wing addition, and a recent laboratory exhaust system upgrade was implemented throughout the North and West Wings in the 2008 timeframe.

Supply Air

The supply air systems within Brown consist of a series of semi-custom double-wall and modular double-wall air handling units of various vintages. All units are generally in good condition, with the exception of the two older units serving the South Wing that are roughly 20-25 years old. These two air handling units are located in the penthouse of the South Wing and are probably the most in need of upgrade or planned replacement.

The air handling units serving the front portion of the existing building (West Wing) have all been installed in approximately 2008. Two units were installed in the West Wing penthouse (AHU-3, 4 & 5) and one was installed in a basement mechanical room (AHU-6). Two new units were installed at the same time to serve the North Wing and Infill area (AHU-1 & 2), and they are located outdoors on the roof of the infill between the North and South Wings. The units are all double-wall modular York Solution air handling units with steam preheat coils and chilled water cooling coils. Two of the units (AHU-3 and AHU-4) have been provided with steam humidifiers for winter humidification control. At the same time that the air handling units were replaced new ductwork and new VAV boxes were installed throughout the West North Wings.

The two air handling units (AHU-1-1 and AHU-2-1) that serve the South Wing are located in the penthouse of the South Wing and were installed with renovations in approximately 1995. These two units were installed along with three new central laboratory exhaust fans serving the South Wing and along with new chilled water pumps, heating hot water pumps and along with a laboratory exhaust heat recovery system. This laboratory exhaust energy recovery system is a glycol run-around loop system with coils in the exhaust air stream and in the OA stream within the air handling units, with all equipment located in the penthouse.

Reference the floor plans in Appendix A, AHU Zone Diagrams, for areas within Brown served by each AHU described above. These diagrams not only indicate the areas served by each air handling unit but also the square footage served by each AHU by floor.

Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the size of the primary air handling units with the estimate of how loaded the units currently are and what CFM they are currently



operating at. This table also includes what the original design intent was for the % of OA that the units are designed for. This allows for an evaluation of whether the unit can accommodate serving up to 100% wet chemistry laboratories which require 100% exhaust of the laboratory air and 100% OA from the AHU.

Reference the diagrams in Appendix C, Supply and Exhaust Airflow Diagrams, for the general configuration of the primary air handling units and laboratory exhaust fans in Brown. The airflow diagrams also indicate the primary supply and exhaust ductwork risers that may be the limiting piece of infrastructure for future renovations or upgrades. These primary risers have been tagged with riser designations that are also indicated on the floor plans shown in Appendix A, AHU Zone Diagrams.

Reference the floor plans in Appendix F, Space Pressurization Diagrams, for the general space pressurization requirements by floor within Brown. The current transfer air quantities are shown for each laboratory at the door into the lab from the corridor or between laboratories. These diagrams show a basic design intent for guiding future changes and highlight where increases or decreases in transfer are recommended.

Laboratory Exhaust Air

The laboratory exhaust systems serving Brown include two primary combined laboratory exhaust systems. A combined laboratory exhaust system means that general laboratory exhaust air and fume hood exhaust air are combined in the same ductwork system and exhausted with the same exhaust fans. This system approach requires that no fume hood be connected to the combined exhaust system that exhausts any vapor, gas, fume, mist or dust of a type, rating or quantity that meets the definition of hazardous exhaust as defined by the mechanical code. Hazardous exhaust is required to be exhausted in an independent system with dedicated exhaust fans meeting the code requirements for hazardous exhaust systems. Dedicated exhaust systems would also be required where exhausting perchloric acids, radioisotopes or where exhausting biosafety cabinets requiring dedicated exhaust fans for isolation.

One combined exhaust system in Brown includes the three combined general laboratory exhaust fans located in the South Wing penthouse serving specifically the South Wing laboratories. These three general laboratory exhaust fans that discharge through exhaust ductwork stacks that extend up through brick chimney enclosures were installed in approximately 1995. These fans are in good condition and they have also been provided with energy recovery coils located in the ductwork upstream of the fans.

The second combined exhaust system in Brown includes three combined general laboratory exhaust fans located on the roof of the Infill area between the North Wing and South Wing. This combined laboratory exhaust system exhausts the North Wing laboratories and a select few laboratories in the West Wing. These fans were installed in approximately 2008 and are in excellent condition. This system, however, has not been provided with coils upstream in the ductwork for energy recovery.

Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the size of the general combined laboratory exhaust fans with the estimate of how loaded the fans currently are and what CFM they are currently operating at.




Chilled Water, Steam & Pumps

The Brown original West Wing, North Wing and the equipment in the Infill are all served by an existing 6” high pressure steam main (125 psig) that enters the Brown Building on the south side at the basement level. This high pressure steam line from the Campus Boiler House feeds a pressure reducing station serving these areas and is also cross connected to the existing south wing steam pressure reducing station. Both the new pressure reducing station serving the North and West Wings and the older pressure reducing station serving the South Wing are located in the basement mechanical room within the South Wing.

Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the capacities of the chilled water pumps and heating water pumps in Brown.

Fume Hoods

Brown laboratory includes sixty-nine (69) bench fume hoods, two (2) walk-in fume hoods, seven (7) canopy hoods and thirty-one (31) snorkel exhausts. These laboratory exhaust hoods are all generally in good condition and those that are operational are functioning safely and within environmental health and safety standards. The inventory of all fume hood types within Brown (bench hoods, walk-in hoods, canopy hoods and snorkel hoods) is included in Appendix D, Existing Fume Hood Assessment, along with a general conditions assessment and recommendations for upgrade or replacement. Where hoods are recommended for replacement ROM costs have been provided in the COST ANALYSIS portion of the report for future planning purposes.



Drake – Existing HVAC Systems

The original Drake Laboratory Building was designed in 1971 as a classroom laboratory building. The building has been renovated over the years and contains a combination of teaching and research laboratories for use by the Departments of Chemistry and Biochemistry. The building is served by central chilled water and steam from the campus central steam & chilled water plant very near the building.

Supply Air

The original Drake building HVAC supply air system consisted of a field assembled custom air-handling unit (AHU-1) located in the basement. Outside air is drawn in through an areaway located (at grade) in the courtyard formed between Drake Laboratory Building and the three wings of Brown Laboratory. Also in the courtyard are air intakes for the previously renovated Brown south wing. These intakes are at the third floor of the south wing as opposed to at grade. This original AHU is 100% OA and has a single fan, filters, a steam preheat coil, a chilled water cooling coil and a steam humidifier. The unit was refurbished in approximately 2013, with the unit being rebuilt almost entirely, with the supply fan being refurbished, a new variable frequency drive (VFD) installed for capacity control, new controls installed, a new chilled water coil installed and a new humidifier installed. The unit, however, was never installed with a laboratory exhaust heat recovery system.

A second air handling unit (AHU-2) was installed in approximately 2013 to serve just the Organic Chemistry Laboratories 112, 318 and 320. This unit is a semi-custom double-wall 100% OA unit and is located on the roof. The unit has been provided with a steam preheat coil with face-and-bypass capacity control, a steam injection humidifier, a chilled water cooling coil and a single centrifugal fan with VFD for capacity control. This unit provides the increased makeup air needed for the high density of fume hoods required in these laboratories.

Supply air ductwork from AHU-1 includes the original medium pressure round sheet metal ductwork from the basement to two 40” diameter duct risers up through the building to supply the second and third floor laboratories. Airflow control is provided by laboratory supply air control valves installed with the Laboratory Renovation project in approximately 2013.

New rectangular medium pressure supply ductwork from AHU-1 was installed in 2013 from the roof to Organic Chemistry Laboratories 112, 318 and 320. New airflow control valves were installed at that time to provide capacity control associated with the laboratory fume hood and space pressurization system design.

Reference the floor plans in Appendix A, AHU Zone Diagrams, for areas within Drake served by each AHU described above. These diagrams not only indicate the areas served by each air handling unit but also the square footage served by each AHU by floor.

Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the size of the primary air handling units with the estimate of how loaded the units currently are and what CFM they are currently operating at. This table also includes what the original design intent was for the % of OA that the units are



designed for. This allows for an evaluation of whether the unit can accommodate serving up to 100% wet chemistry laboratories which require 100% exhaust of the laboratory air and 100% OA from the AHU.

Reference the diagrams in Appendix C, Supply and Exhaust Airflow Diagrams, for the general configuration of the primary air handling units and laboratory exhaust fans in Drake. The airflow diagrams also indicate the primary supply and exhaust ductwork risers that may be the limiting piece of infrastructure for future renovations or upgrades. These primary risers have been tagged with riser designations that are also indicated on the floor plans shown in Appendix A, AHU Zone Diagrams.

Reference the floor plans in Appendix F, Space Pressurization Diagrams, for the general space pressurization requirements by floor within Drake. The current transfer air quantities are shown for each laboratory at the door into the lab from the corridor or between laboratories. These diagrams show a basic design intent for guiding future changes and highlight where increases or decreases in transfer are recommended.


The laboratory exhaust system serving Drake includes a single combined laboratory exhaust system. A combined laboratory exhaust system means that general laboratory exhaust air and fume hood exhaust air are combined in the same ductwork system and exhausted with the same exhaust fans. This system approach requires that no fume hood be connected to the combined exhaust system that exhausts any vapor, gas, fume, mist or dust of a type, rating or quantity that meets the definition of hazardous exhaust as defined by the mechanical code. Hazardous exhaust is required to be exhausted in an independent system with dedicated exhaust fans meeting the code requirements for hazardous exhaust systems. Dedicated exhaust systems would also be required where exhausting perchloric acids, radioisotopes or where exhausting biosafety cabinets requiring dedicated exhaust fans for isolation.

The buildings laboratory exhaust system was modified in 2013 to create a new central combined laboratory exhaust system, with three central 35,000 CFM centrifugal exhaust fans installed on the roof of Drake Laboratory to exhaust all general exhaust and fume hood exhaust in the building. These new exhaust fans are single-width, single-inlet, centrifugal exhaust fans with airfoil fan blades. The exhaust fans have been provided with VFD’s for fan speed control and have discharge sound attenuators for acoustical noise control.

Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the size of the general combined laboratory exhaust fans with the estimate of how loaded the fans currently are and what CFM they are currently operating at.





Drake is served by an existing 6” high pressure steam main (125 psig) that enters the Drake Building on the southwest side at the basement level. This high pressure steam line from the Campus Boiler House feeds a pressure reducing station serving these areas and also is cross connected to the existing south wing steam pressure reducing station. Both the new pressure reducing station serving the North and West Wings and the older pressure reducing station serving the South Wing are located in the basement of the South Wing. Chilled Water (8” CHWS/CHWR) enters the Drake building along the west side of Drake at the basement level. The chilled water pumps and hot water pumps serving Drake are all located in the basement mechanical room.

Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the capacities of the chilled water pumps and heating water pumps in Drake.

Fume Hoods

Drake laboratory includes seventy-three (73) bench fume hoods, one (1) walk-in fume hood and one hundred and fourteen (114) snorkel exhausts. These laboratory exhaust hoods are all generally in good condition and those that are operational are functioning safely and within environmental health and safety standards. Many are currently inactive and those that have not been utilized in over a year should be more fully evaluated for workability and replaced if necessary. The inventory of all fume hood types within Drake (bench hoods, walk-in hoods and snorkel hoods) is included in Appendix D, Existing Fume Hood Assessment, along with a general conditions assessment and recommendations for upgrade or replacement. Where hoods are recommended for replacement ROM costs have been provided in the COST ANALYSIS portion of the report for future planning purposes.



III. EXISTING HVAC SYSTEMS ASSESSMENT & RECOMMENDATIONS

Assessment of Existing HVAC Systems

In order to assess the limitations of the primary laboratory HVAC equipment, rough calculations have been performed to better understand the general requirements for any current or future laboratory space within the two buildings. The three primary laboratory types that we performed calculations for and would expect to see in the buildings include the following:

Organic Chemistry Teaching Laboratory: Twelve hundred (1200) square feet, twenty four (24) students, 10 watts/square foot laboratory equipment load, six (6) 8-foot teaching fume hoods, two (2) 6-foot bench fume hoods.

General Chemistry Teaching laboratory: Twelve hundred (1200) square feet, twenty four (24) students, 10 watts/square foot laboratory equipment load, two (2) 6-foot bench fume hoods.

General Chemistry Research Laboratory: Six hundred (600) square feet, four (4) researchers, 10 watts/square foot laboratory equipment load, two (2) 6-foot bench fume hoods.

Utilizing the above criteria, the following will be utilized to evaluate the existing air systems capability and space airflows to serve future laboratory upgrades or renovations. The following airflows are a maximum airflow that we would expect to be required at the laboratory space level:

Organic Chemistry Teaching Laboratory: 9.9 CFM/SF

General Chemistry Teaching laboratory: 2.6 CFM/SF

General Chemistry Research Laboratory: 2.8 CFM/SF

Utilizing a standard diversity factor of 80%, the following airflows are a maximum airflow that we would expect to be required at the laboratory AHU or General Lab Exhaust Fans for the same three typical space types:

Organic Chemistry Teaching Laboratory: 7.9 CFM/SF

General Chemistry Teaching laboratory: 2.1 CFM/SF

General Chemistry Research Laboratory: 2.2 CFM/SF



Brown

Supply Air

Utilizing the criteria listed above for future long term capacity requirements, the following is an assessment of the capacity of the existing air handling units serving Brown. Utilizing this assessment recommendations have been provided for each air handling unit, indicating which should remain and be reused as currently operating and which should be replaced in their entirety because they either do not provide the capacity required or because their condition is not adequate as indicated in the Appendix B, Primary HVAC Equipment Inventory.

(*) – Assumes 75% of spaces on this AHU unit in the future are classrooms or offices requiring only 1 CFM/SF and 25% of spaces on this AHU unit would be laboratories requiring 2.2 CFM/SF

An aspect of the air systems that can be a significant limiting factor for future renovation projects is the capacity of the ductwork airflow risers. These vertical risers are typically expensive to upgrade in order to perform small renovations on a floor. The general intent therefore, in order to keep individual renovation costs down, is to have the horizontal ductwork on the floor associated with the proposed renovation be all that is required to be modified. In order to better understand the limitations of the existing vertical supply risers currently in the building we have performed an assessment of each of the Major Ductwork Risers in the building, for future planning purposes. We have not looked at the numerous smaller vertical risers in the building as they are typically limited to serving the existing spaces in their current capacities. The following is our assessment of these major vertical risers:

(*) - The estimates of maximum airflow CFM for the duct risers is an estimate based on utilizing a maximum duct velocity for acoustical criteria of 2500 fpm for medium pressure ductwork (supply & exhaust) and 2000 fpm for low pressure ductwork (return).


The combined general laboratory exhaust fans serving the Brown South Wing appear to have adequate capacity for current and future loads; however, the units are getting near the end of their useful life and should be replaced soon. The combined general laboratory exhaust fans serving the Brown North Wind and Brown West Wing laboratories appear to have adequate capacity for current and future loads. Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the size of the general combined laboratory exhaust fans with the estimate of how loaded the fans currently are.


The primary steam and chilled water services (which come from the Campus Boiler House and Campus Chilled Water Plant) appear adequate for current and future loads. The chilled water and heating hot water pumps as well appear in good condition and adequate for current and immediate future loads.

Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the capacities of the chilled water pumps and heating water pumps in Brown.

Fume Hoods

All laboratory exhaust hoods in Brown are in generally in good condition, and those that are operational are functioning safely and within environmental health and safety standards. The inventory of all fume hood types within Brown (bench hoods, walk-in hoods and snorkel hoods) is included in Appendix D, Existing Fume Hood Assessment, along with a general conditions assessment and recommendations for upgrade or replacement.

(*) – Subtracting the 29,000 CFM currently supplied to Organic Chemistry Labs 112, 318 & 320 leaves enough airflow to serve an additional 5,500 SF at a supply airflow density of 2.0 CFM/SF.

An aspect of the air systems that can be a significant limiting factor for future renovation projects is the capacity of the ductwork airflow risers. These vertical risers are typically expensive to upgrade in order to perform small renovations on a floor. The general intent therefore, in order to keep individual renovation costs down, is to have the horizontal ductwork on the floor associated with the proposed renovation be all that is required to be modified. In order to better understand the limitations of the existing vertical supply risers currently in the building we have performed an assessment of each of the Major Ductwork Risers in the building, for future planning purposes. We have not looked at the numerous smaller vertical risers in the building as they are typically limited to serving the existing spaces in their current capacities. The following is our assessment of these major vertical risers:

DN-SA-1 Supply 40” dia. GR, 1, 2, 3 26,960 21,800 0

DN-SA-2 Supply 40” dia. GR, 1, 2, 3 19,895 21,800 1,905

DS-SA -4 Supply 40x14 1 6,510 9,700 3,190

(*) - The estimates of maximum airflow CFM for the duct risers is an estimate based on utilizing a maximum duct velocity for acoustical criteria of 2500 fpm for medium pressure ductwork (supply & exhaust) and 2000 fpm for low pressure ductwork (return).


The combined general laboratory exhaust fans serving the Drake appear to have adequate capacity for current and future loads. If additional organic chemistry teaching laboratories are added to Drake, however, an additional exhaust fan would need to be added to the system as indicated in the Drake Hall Lab Renovation Feasibility Study performed by Jacobs dated October 10, 2014. Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the size of the general combined laboratory exhaust fans with the estimate of how loaded the fans currently are.


The primary steam and chilled water services (which come from the Campus Boiler House and Campus Chilled Water Plant) appear adequate for current and future loads. The chilled water and heating hot water pumps as well appear in good condition and adequate for current and immediate future loads.

Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the capacities of the chilled water pumps and heating water pumps in Drake.

Fume Hoods

All laboratory exhaust hoods in Drake are in generally in good condition, and those that are operational are functioning safely and within environmental health and safety standards. Many are currently inactive and those that have not been utilized in over a year should be more fully evaluated for workability and replaced if necessary. The inventory of all fume hood types within Drake (bench hoods, walk-in hoods and snorkel hoods) is included in Appendix D, Existing Fume Hood Assessment, along with a general conditions assessment and recommendations for upgrade or replacement. Where hoods are recommended for replacement ROM costs have been provided in the COST ANALYSIS portion of the report for future planning purposes.






IV. COST ANALYSIS

Supply Air

Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the rough order-of-magnitude (ROM) replacement costs for the primary air handling units recommended to be replaced within the next 10 year capital funding period.

Exhaust Air

Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the rough order-of-magnitude (ROM) replacement costs for the primary combined general laboratory exhaust fans recommended to be replaced within the next 10 year capital funding period.


Reference the table in Appendix B, Primary HVAC Equipment Inventory, for the rough order-of-magnitude (ROM) replacement costs for the primary chilled water and heating hot water pumps recommended to be replaced within the next 10 year capital funding period.

Fume Hoods

The fume hood assessment determined that none of the existing fume hoods needed to be replaced immediately. It is recommended that those fume hoods shown with a “fair” or “poor” condition assessment be replaced during any future renovation of the specific laboratory they reside in. This would be done in order to change the type, size or configuration of fume hoods in the laboratory to fit a new program requirement. In order to help plan for these future changes in fume hoods, rough order-of-magnitude (ROM) costs have been provided on the next page for various fume sizes and types.



Fume Hoods Replacement Costs

Rough order-of-magnitude (ROM) costs for 4’ Bench Fume Hood:

Demo Existing Fume Hood & Associated Base Cabinet $750 (**) Disconnect Utilities (power, water, drain, gas) $500 Install New Fume Hood & Associated Base Cabinet $9,500 Connect Utilities (power, water, drain, gas) $500 Demo and Install new Air Valves $1,000 Rebalance & Adjust Controls $750 Total Cost (4’ Fume Hood and Base Cabinet) $13,000

Rough order-of-magnitude (ROM) costs for 6’ Bench Fume Hood:


Rough order-of-magnitude (ROM) costs for 8’’ Bench Fume Hood:


Rough order-of-magnitude (ROM) costs for 6’’ Walk-in Fume Hood:

Demo Existing Fume Hood & Associated Base Cabinet $750 (**) Disconnect Utilities (power, water, drain, gas) $500 Install New Fume Hood & Associated Base Cabinet $18,500 Connect Utilities (power, water, drain, gas) $500 Demo and Install new Air Valves $2,500 Rebalance & Adjust Controls $750 Total Cost (6’ Walk-in Hood and Base Cabinet) $23,500
