SITE VISIT AND SITE INVESTIGATION REPORT

MECHANICAL & HVAC SYSTEMS

FOR

NOAA - MARINE OPERATIONS CENTER - ATLANTIC (MOC-A)

BUILDINGS 1 and 2

EXECUTIVE SUMMARY:

1. Some equipment is near or past the end of its useful life and should be planned for replacement. This includes, but is not limited to the following:

a. The control system is currently a shambles and is of “little to no value” in it’s

“as-is” condition. We recommend complete replacement design efforts begin immediately after completion of Item 6. The probable cost of a current Building Automation System is expected to be approximately$XXX to $XXX in total for both Building 1 and 2.

b. Controls in Building 1 include chiller and boiler plant, as well as air handling units and rooftop units. Potentially, these controls could be repaired and made useable for a few more years (if Item 1a is not possible at this time).

Probable cost of temporary repair is approximately $XXX.

c. Controls in Building 2 are in a state of disrepair with regard to the boiler operation (and are unacceptable). Thermostats on A/C systems may be

NOAA Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia Site Visit and Site Investigation March 2016 Mechanical and HVAC Systems Page 1 made operable once the boiler and heating hot water systems controls are replaced. Probable cost of temporary repair is approximately $XXX.

2. Some additional equipment in Building 1 and 2 are near or past the end of its useful life and should be planned for replacement. This includes, but is not limited to the following:

a. Boiler replacement (Building 2) - probable cost $XXX

b. Water cooled chiller replacement - probable cost $XXX

c. Misc. AHU/RTU replacement - probable cost $XXX

d. DX split/Mini-split replacements - probable cost $XXX

3. There is debate over the current condition of the Building 1 existing chiller and the need to perhaps replace it. One compressor is currently disconnected for some reason however, the other three of four are operating currently. This allows for continued use of this machine for an additional three to five years in my opinion with a planned replacement in that time frame (barring a decision for complete system upgrade/renovation).

4. An HVAC repair project could be developed to address planned equipment replacement and new HVAC system controls, with an associated probable cost of

$620,000 addressing immediate needs and should direct replacement of these components (in lieu of reuse) also integrate some current code ventilation standards

NOAA Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia

Mechanical and HVAC Systems Page 2

(not currently being met) the probable costs would rise to close to $XXX to

$XXX.

5. Should a complete HVAC system replacement for both buildings be considered

(utilizing new technology such as variable refrigerant flow (VRF) systems), the probable cost would be close to $XXX to $XXX.

6. There are some existing plans available for the facility for the original construction of Building 1 and 2 (1979) and some major renovations (the Facility Restoration

Plans - Arriba 2009) for Building 1 and 2. There have been many revisions and/or alterations to the HVAC systems that have heretofore not been completely documented. We recommend that all existing HVAC system plans be incorporated in a master set of HVAC ”record set drawings” and this “missing information” be gathered in a detailed pre-design on site survey - the result of which will be accurate

HVAC background CAD drawings upon which to evaluate and identify potential

HVAC enhancement design alternatives moving forward. The probable cost of this pre-design survey is likely approximately $XXX.

7. There is currently no HVAC service agreement in place and filters/routine maintenance needs have not been addressed for approximately three (3) months.

It is recommended that a short term (no more than one (1) year) agreement be implemented, or alterative approach (filter changing should be done ASAP) to a service agreement should be initiated (in-house service). It would appear that the existing Aero Mechanical offer for these continued services is reasonable for this purpose, and is therefore recommend at this time. Should Item 1 above be implemented it would also allow an on-site meeting between Aero personnel and those developing record set information to help ensure nothing is missed.

8. Site visit observations and related photos indicate the presence of some asbestos containing materials (ACM). It is expected that some 9" x 9" VAT (floor tile) is ACM and some thermal system (pipe) insulation is expected (pipe elbows) to be ACM.

It is our understanding that no comprehensive ACM facility inspection has been done

(although some testing has been done). A comprehensive inspection by an EPA certified inspector is likely $6,000, if this survey has not yet been done.

BACKGROUND:

The air conditioning systems were reviewed from an engineering perspective via three days of site visits on February 23, 24, and 25, 2016 on-site.

The facility presently consists of two buildings. Building 1 is 18,00 square feet with an additional

2,000 to 4,000 square feet square of added interior space built out. Total conditioned space approximately 21,000 square feet. Building 2 is 10,000 to 11,000 square feet with again some interior space built out that may not be accurately reflected on plans. Total conditioned space approximately

12,400 square feet.

This report is based upon information provided via existing design drawings and related information which were provided to give the reviewer a basic understanding of the systems installed, their interconnection at the time of the building construction, observation of current conditions, and from the outward physical condition viewed by this reviewer.

The purpose of the review was to establish and document without destructive testing, the general condition of equipment and evaluate the remaining average life expectancy and condition of the various mechanical HVAC systems and associated equipment.

NOAA Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia

Mechanical and HVAC Systems Page 4

It appears from a review of records related to this project that the HVAC systems in Building 1 in the building are generally speaking operating in accordance with the original design intent reflected on the original drawings. Numerous modifications and/or equipment replacement work has been done on an “as needed” basis over the years, some of which is not documented.

The original control system for Building 1 (pneumatic) has been removed over the years and has been replaced with various technologies including line voltage thermostats, manual contactors/switches for start/stop and some limited currently (non-accessible) low voltage digital controls. A limited computer based control system was installed with operator workstation software, however, this software has been corrupted and is currently nonfunctional.

The control systems for Building 2 are ineffectual. The boiler controls are inoperable, except for a manual start/stop. Cooling systems are overpowered by the uncontrolled heat (when boiler energized). National Oceanic and Atmospheric Administration (NOAA) requested that Associated

Design Group, Inc. (ADG) provide a site visit/site investigation at its facility in Norfolk, Virginia, that provides operations and support for fleet vessels. The facility is occupied by the Marine Operations

Center – Atlantic (MOC-A) which provides a base for vessel operations and support to the Atlantic fleet. Building 1 houses office space and a warehouse. This building is served by a boiler, chiller, and cooling tower as primary equipment. Most of the primary equipment has been replaced since

2000. The boiler was replaced in 2004, the chiller was replaced in 2006, and the cooling tower was replaced in 2007. The primary equipment serves a multi-zone air handler located on the ground floor.

The primary equipment serves large hot water unit heaters in the warehouse, one small air handler in the warehouse mezzanine and another AHU adjacent to the Radio Room. DX rooftop units serve the mezzanine offices. Several “mini-splits” have been added to office spaces. There are no existing drawings associated with this work that have been identified to date.

NOAA Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia

Mechanical and HVAC Systems Page 5

Building 2 houses offices and electronic instrumentation workshop on the first floor and computer room on the second floor. The Atlantic Hydropgraphic Branch of NOAA is housed on the second floor. Primary equipment consists of a boiler (which is beyond its expected life and should be replaced), and DX cooling equipment. The computer room is served by a 12-ton computer room air conditioning unit.

Architecturally the buildings at this facility were previously evaluated and are outside the scope of this

HVAC site investigation.

With respect to the HVAC systems in Building 1, the boiler, chiller, cooling tower and one of the air handlers in Building 1 have been replaced recently as discussed above. There are two remaining air handling units, the existing ductwork distribution system, temperature zoning and controls in Building

1 each of which are in fair to poor condition. Particularly, the control system is reported to be ineffectual in regard to meeting occupant space cooling and heating comfort needs.

It appears that acceptable maintenance for the various pieces of HVAC equipment has been provided. There are however, typical minor deficiencies that were reported in our site survey. Our findings of these minor HVAC system deficiencies include the following:

Building 1:

The building contains approximately 21,000 square feet of space that is heated/cooled. This is made up of 9,000 square feet of office space, and 11,000 square feet of warehouse.

Original Office Space:

Building 1 original office areas consist of office space that is air conditioned and heated. Air conditioning for the building was originally provided by two chilled water air conditioning units

NOAA Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia

Mechanical and HVAC Systems Page 6 furnished in 1964 with an installed capacity of 16 tons. Heating was provided by a gas fired hot water boiler with a design capacity of 960 MBH. At some point around 1964, a third HVAC unit, a multi-zone air handler, was added in the 1st floor boiler room with a capacity of 10 tons. In 1979, the HVAC system in Building 1 was modified via some rezoning and rebalancing of the systems. The air conditioning system was later supplemented by the addition of 4 through the wall air conditioners and

3 small split air conditioning units. The original boiler was replaced in 2004 and the original chiller and the control air compressor were replaced in 2006 and the cooling tower was replaced in 2007.

Warehouse Space:

The warehouse is not air conditioned. It is heated by the hot water boiler located in Building 1 and ventilated through roof mounted exhaust fans.

Office Areas (with in Warehouse Space):

At some point between 1964 and 1979, offices were added to portions of the warehouse areas along with offices being added to the mezzanine. This area represents total conditioned space of approximately 4,000 square feet (of the 11,000 square foot warehouse area). An air handler located on the mezzanine on the East side of the warehouse and two roof top units located on the West end were added to condition these spaces. These units were removed and the office spaces are now cooled by two roof top units, 5 window air conditioners and 12 small split system air conditioning units

(mini-split air conditioners).

Building 2:

Building 2 consist of approximately 12,400 square feet of office space. Air conditioning for the building was originally provided by one direct expansion/water cooled air conditioning unit with an installed capacity of approximately 27 tons, and heating provided by a gas fired hot water boiler with a capacity of approximately 400 MBH (past its expected life and inoperable controls). In 1979, the HVAC system in Building 2 was modified with the addition of an 11 ton roof top air conditioning unit, which also

NOAA Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia

Mechanical and HVAC Systems Page 7 included ductwork modifications. A computer room project involved the addition of a computer room on the 2nd floor, which required the installation of a 12 ton air cooled (split-system) air conditioning unit. Presently, the air conditioning system has been augmented by the addition of four each window air conditioners on the 2nd floor. No documentation concerning this work is yet available via plans/specifications.

EXHAUST AIR SYSTEMS:

All exhaust fans located within the building are constant volume exhaust systems. These fans operate continuously, which means that a constant amount of air is exhausted from various areas of the building twenty-four hours per day, seven days a week. In order to maintain a slight positive pressure within the building, this requires that the HVAC systems must introduce fresh air into the building at a rate above some minimum air volume (to make up for building exhaust).

CHILLED WATER SYSTEM:

The central chiller plant consists of a single, water cooled, Trane chiller (CGWF 0604 CB0U AA1C

L1D1 NN03 N0N2) - nominal 60 tons. The unit is 480-3-60 electrical service with four (4) R-22 compressors. It is connected to chilled water coils in air handling equipment, via a primary pumping system consisting of three (3) HP primary chilled water pump and twp (2) heating hot water pumps -both one and one-half (1-1/2 HP).

The total connected load for the chilled water system appears to be approximately 144 GPM. For most of the year, the chiller and related pumps operate in order to satisfy the load. The chilled water system is supplemented by multiple direct expansion (DX) HVAC systems on the roof and via split/mini-split configurations with stand alone controls.

Chilled water piping installed is insulated generally with fiberglass pipe insulation. The insulation on condenser water piping is also fiberglass pipe insulation, is protected by an aluminum jacket where

NOAA Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia

Mechanical and HVAC Systems Page 8 exposed to weather such as in the cooling tower yard. Insulation on chilled water piping run within the building is fiberglass insulation with an ASJ (all-service jacket) for the most part. Majority of the chilled water piping is run above finished ceilings and is accessible from the lay-in ceiling grid

(suspended acoustical ceiling) system.

HEATING HOT WATER SYSTEM:

The heating hot water system plant consists of two (2) boilers rated at 960 MBTU input (Building 1) and 400 MBTU output (Building 2). Heating hot water flow is generated by multiple primary hot water system pumps located in each building. The boiler in Building 2 is beyond its useful life and the controls are inoperable (it must be manually switch “on” when space is too cold and “off” when space is too hot.

Piping from the mechanical room runs above the various ceilings to serve air distribution boxes as well as air handling units (AHUs) and rooftop A/C units. The heating hot water piping is generally insulated with fiberglass insulation and an ASJ (all-service jacket). Note: Some ACM pipe insulation fittings were observed perhaps requiring additional ACM inspection work and abatement, prior to an

HVAC construction contract.

FRESH AIR & INDOOR AIR QUALITY SYSTEMS:

Outdoor air or fresh air is introduced into the building directly into the fresh air intake of individual roof top units and central station air handling units. Outdoor air is continuously drawn into the A/C unit via the suction pressure of the A/C fan when operating. There is no separate building fresh air system which introduces conditioned or tempered air to the building occupants. Current ventilation levels appear to be below current ASHRAE standards for this occupancy.

BUILDING TEMPERATURE CONTROLS:

NOAA Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia

Mechanical and HVAC Systems Page 9

The temperature control system as presently installed is a limited DDC (Direct Digital Control) electronic type Building Management System (BMS). The control system controls the operation of pumps, air conditioners, fans, and chillers, in the central plant. Facility maintenance personnel indicated that systems are currently not working to their satisfaction. The facility front-end interface is currently nonfunctional as it appears necessary files have been moved, and/or deleted so the software continually looks for missing data or files and will not start.

Building 1 HVAC System Deficiencies Previously Identified - Office Areas:

1. Inadequate temperature controls. There are miscellaneous thermostats that are nonfunctioning. Due to the age of the present pneumatic controls, calibration of devices is needed. The present system is not state of the art and does not allow user interface. The replacement of the temperature control system should be implemented to improve system efficiencies and the working environment.

2. Undersized air conditioning units. The original air handling units are undersized, first from the standpoint that the coils are designed for a leaving air temperature of

60°FDB/59°FWB, these leaving air conditions were obtained from the equipment schedules on the construction documents. Those conditions will result in a humid environment of about 65% at 75°F. In order for space conditions of 75°F at 50%RH the leaving air temperature needs to be 55°F, that is 5 degrees colder than what the units are presently capable of. Another indication of under capacity is the number of split systems and through the walls units that have been added for additional cooling.

The replacement of the air handling system should be implemented to improve system efficiencies and the working environment.

NOAA Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia

Mechanical and HVAC Systems Page 10

3. Improper zoning. The existing air handling system doesn’t have the ability to properly control different areas. This is not only due to faulty controls, under capacity units, but also due to controlled zones not covering the spaces adequately. The replacement of the air handling system zoning should be implemented to improve system efficiencies and the working environment.

4. Mechanical equipment exceeding life expectancy. The air handlers, piping and pumps for the air conditioning and heating system have exceeded the normal life expectancy of 20 years. Air handler #3, the chiller and cooling tower are new within the last decade. Other items, such as the original air handler # 1 & #2 are around 40 years old and should be replaced. The replacement of the air handling system should be implemented to improve system efficiencies and the working environment.

5. Leaking ductwork and inadequate sizes and configurations. During our inspection of the ductwork system in the attic, we found several air leaks in the ductwork. Some of this can be repaired, but there again some of the ductwork is close to 40 years old. Also, over the years reconfiguration of office spaces did not address the required ductwork changes. The replacement of the ductwork should be implemented to improve system efficiencies and the working environment.

6. Inefficient system types. Building 1 uses 2 chilled water air handling units, 2 rooftop

DX units, 5 window air conditioners, 4 thru the wall and 15 split air conditioning units.

None of the units are variable volume units. The replacement of the air handling systems should be implemented to improve system efficiencies and the working environment.

NOAA Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia

Mechanical and HVAC Systems Page 11

7. Inability to balance air handling systems. Due to the condition of the air handling units, ductwork and the location of balancing dampers or the lack of balancing dampers; the ability to balance the air handling systems is almost a fruitless effort especially with replacement of the existing systems is required. The replacement of the complete air handling system would take care of this deficiency and improve system efficiencies and the working environment.

8. Inadequate insulation. Over the years the insulation on ductwork and the piping systems have become loose or been removed which affects the efficiency of the systems. The replacement of the ductwork and piping insulation should be implemented to improve system efficiencies and the working environment. Some

ACM pipe insulation may be encountered.

Building 1 HVAC System Deficiencies - Warehouse Areas:

Warehouse Area:

1. All of the units in the warehouse area are either self contained or they are a single zone covering several offices. The replacement of the temperature control system should be implemented to improve system efficiencies and the working environment.

Existing temperature controls are inadequate.

Office Areas:

1. The systems are apparently under capacity, when you have 2 roof top units and then to supplement those units it takes 5 window units and 12 split system units. The replacement of the air handling system for the office area and the heating system for

NOAA Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia

Mechanical and HVAC Systems Page 12 the warehouse areas should be undertaken to improve system efficiencies and the working environment, when possible.

2. Improper zoning is evident within this space. The replacement of the air handling system should be implemented to improve system efficiencies and the working environment.

3. Mechanical equipment exceeding life expectancy. The roof top units and piping have exceeded the normal life expectancy of 20 years. Some items, such as the 5 window air conditioning units and the 15 split systems are not that old but are showing signs of wear and tear. The replacement of the air handling system should be implemented to improve system efficiencies and the working environment.

4. Inefficient system types. The use of 19 separate DX type units to air condition the warehouse office space is very inefficient type of system. The replacement of the air handling system should be implemented to improve system efficiencies and the working environment.

Building 2 HVAC System Deficiencies:

1. The boiler for Building 2 is beyond its useful life and the controls are nonfunctional.

It should be replaced as soon as possible.

2. Mechanical equipment has exceeded its expected useful life expectancy. The roof top unit is around 30 years old and air handler #1, hot water piping, and pumps for the heating system (in addition to the boiler) have exceeded the normal life expectancy of 20 years. Some items, such as the air handler # 1, the boiler and

NOAA Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia

Mechanical and HVAC Systems Page 13 water cooled DX compressor are around 40 years old and should be replaced. The replacement of the air handling system and associated boiler / HW system should be implemented to improve system efficiencies and the working environment.

3. Inadequate temperature controls. There are miscellaneous thermostats are non-functioning, due to the age of the present pneumatic controls calibration of devices is needed along with the present system is not state of the art and does not allow user interface. The replacement of the temperature control system should be implemented to improve system efficiencies and the working environment.

4. Undersized air conditioning units. The original air handling units are undersized, first from the standpoint that the coils are designed for a leaving air temperature of

60°FDB/59°FWB, these leaving air conditions will result in a humid environment of about 65% at 75°F. In order for space conditions of 75°F at 50%RH the leaving air temperature needs to be 55°F, that is 5 degrees colder than what the units are presently capable of. Another indication of under capacity is the number of split systems and thru the walls units that have been added for additional cooling. The replacement of the air handling system should be implemented to improve system efficiencies and the working environment.

5. Improper zoning. The existing air handling system doesn’t have the ability to properly control different areas. This is not only due to faulty controls, under capacity units, but also due to controlled zones not covering the spaces adequately. The replacement of the air handling system should be implemented to improve system efficiencies and the working environment.
