Two US Navy facilities, Naval Air Station (NAS) Oceana and Naval
Amphibious Base (NAB) Little Creek, are represented in this document by
sixteen buildings. These buildings are only a small sample of the
diverse types of buildings found at each facility. These buildings were
selected by the US Navy Public Works Center (PWC) - Norfolk and Oceana's
and Little Creek\'s Base Civil Engineering (BCE) Energy Managers. The
buildings selected are candidates for geothermal heat pump
(GHP)-centered energy savings improvement projects. Further, these
buildings have personnel to champion the cause for achieving energy and
cost savings through energy savings performance contracting (ESPC).

These 16 buildings are characterized to show the current operations of
each and to provide insight for the development of GHP-centered energy
and cost saving opportunities at NAS Oceana and NAB Little Creek. While
this sampling of buildings only represents a small portion of the square
footage at each facility, it is valuable in demonstrating the potential
for energy savings opportunities through the application of geothermal
heat pump technology.

This site data package (SDP) consists of a text document (this document)
in hard copy and in WordPerfect 6.1 (GHP.wpd) and MSWord 6.0 (GHP.doc),
a workbook of spreadsheets in Excel 5.0 (GHPWB.xls), and a package of
supporting documents and engineering drawings in hard copy format
(available from Kinko\'s-Farragut, TN (423) 531-8307). Most table
references in the text document refer to spreadsheets in the Excel
workbook. Attachment references correspond to information provided in

### **1.2.1 NAS Oceana** {#nas-oceana-1 .unnumbered}

NAS Oceana is located within the city limits of Virginia Beach, Virginia
and covers approximately 6,000 acres of land. Norfolk International
Airport is approximately 20 miles west of NAS Oceana. The air station is
located 36 degrees, 54 minutes latitude and 76 degrees, 12 minutes
longitude at 22 feet above sea level. Attachment 20 shows the buildings
and area roads for NAS Oceana.

### **1.2.2 NAB Little Creek** {#nab-little-creek-1 .unnumbered}

NAB Little Creek is located at the extreme northwest corner of Virginia
Beach and Norfolk. Norfolk International Airport is located just south
of Little Creek. The airport flight path is directly above one pierfront
area. Attachment 21 shows the buildings and area roads for NAB Little
Creek.

## 1.3 Climate Conditions {#climate-conditions .unnumbered}

The winter design dry bulb temperature is 20 degrees Fahrenheit (F) (at
99% design) and 22 degrees Fahrenheit (at 97.5% design). The summer
design dry bulb and mean coincident wet-bulb (in degrees Fahrenheit) is
93/77(at 1% design), 91/76 (at 2.5% design) and 89/76 (at 5%

design). The mean daily range is 18 degrees Fahrenheit. Engineering data
provided by Atlantic Division Naval Facilities Engineering Command
(LANTDIV) indicates 3,639 heating degree-days and 1,485 cooling
degree-days for the area.

## 1.4 Physical Plants {#physical-plants .unnumbered}

### **1.4.1 NAS Oceana** {#nas-oceana-2 .unnumbered}

[Electrical Distribution]{.underline}

Transmission lines to the switching station are owned, operated, and
maintained by Virginia Power. The high voltage framework and main
switching station are owned and maintained by the Navy. The Navy also
owns and maintains the 4.16-kilovolt and 13.2-kilovolt electrical
distribution systems located inside the base. Included in these are four
substations.

[Domestic Water]{.underline}

The City of Norfolk under contract with PWC Norfolk provides domestic
water and sewer service to NAS Oceana. Domestic water is wheeled through
the city of Virginia Beach\'s distribution system to a master meter. The
Navy owns and maintains the piping distribution system from the master
meter to the individual buildings or facilities inside the base.

Water is heated for use by electric or steam converter hot water heaters
in each building. In some buildings, steam converters for winter use and
electric heaters for summer use heat domestic hot water. In those
buildings, steam is valved off during the summer months. Most buildings
have steam converters for water heating with no electric backup. In the
summer months, steam is valved off to space heating systems in order to
supply steam service only for domestic water heating.

[Cooling Water]{.underline}

Chilled water for the majority of NAS Oceana is locally generated at
each building by air cooled chillers. A small portion of NAS Oceana is
served by a central chilled water system. The system, consisting of
three 150-ton air cooled chillers, provides chilled water service to a
cluster of barracks. It should be noted that this area/system is not
part of the evaluation package.

[Heating System]{.underline}

Oceana\'s steam plant consists of three 60,000 pounds per hour dual fuel
boilers. The primary fuel source is natural gas with oil as the
secondary fuel.

### **1.4.2 NAB Little Creek** {#nab-little-creek-2 .unnumbered}

[Electrical Distribution]{.underline}

Transmission lines to the main substation and the high voltage framework
as well as the two large transformers are owned, operated and maintained
by Virginia Power. The Navy owns and maintains the 13.2-kilovolt
electrical distribution system located inside the base. The Navy also
owns and maintains the main substation.

[Domestic Water]{.underline}

Domestic water and sewer service is provided by the City of Norfolk and
is wheeled through the city of Virginia Beach\'s distribution system to
a master meter. The Navy owns and maintains the distribution system from
the master meter to the individual buildings or facilities.

Water is heated by electric or steam converter hot water heaters in each
building. In some buildings, steam converters for winter use and
electric heaters for summer use heat domestic hot water. In those
buildings, steam is valved off during the summer months.

[Cooling Water]{.underline}

Chilled water is locally generated at each building by air cooled
chillers. Some buildings also use DX systems to provide cooling.

[Heating System]{.underline}

Little Creek\'s steam plant consists of three, 90,000 pounds per hour,
coal-fired boilers. There are no back-up boilers. Steam plant efficiency
details are provided in Attachment 41.

Some buildings have independent, gas-fired, package heating systems.
Buildings described in this site data package do not use these types of
systems.

## 1.5 Energy Vision {#energy-vision .unnumbered}

Arthur D. Little has developed an Energy Vision for each site. The
purpose of the report is to discuss the current status of both NAS
Oceana and NAB Little Creek, define the needs of each base, prioritize
the options available, and develop the energy vision that will help
guide future projects. One of the major actions identified by the plan
was to use energy more efficiently.

The main focus of the Energy Vision is to transition the extensive steam
distribution system into nodes. This new approach would ultimately phase
out the existing central steam distribution system to more localized
service areas, thereby reducing long runs of steam and condensate lines.

This approach is a main objective for all energy projects at both
facilities. All projects are subject to review for compliance with the
Energy Vision. Attachments 39 and 40 show the Energy Vision for NAS
Oceana and NAB Little Creek, respectively.

## 1.6 Energy Consumption {#energy-consumption .unnumbered}

An overview of facility energy consumption at both sites is discussed
below. Additional detail is provided in Section 5. Energy consumptions
for specific buildings are provided in Section 3.

### **1.6.1 Oceana** {#oceana .unnumbered}

The total cost of energy delivered to Oceana was \$8.2 million in FY96.
This includes PWC costs for electricity procurement and distribution,
production and distribution of steam, and purchase of natural gas.
Attachment 39, the NAS Oceana Energy Vision, details the costs of energy
purchased, generated, and delivered in FY96. Of the energy purchased,
electricity was 44% of the total energy costs, natural gas was 5%, and
fuel oil was 1%. Steam generation was 27% of the energy costs. Steam
distribution and electrical distribution made up 7% and 14%,
respectively. The administration and other costs are 2%, which is the
operating budget of PWC.

[Electric]{.underline}

The main meter to the base is located at Harper\'s Road. The fiscal year
1997 electricity consumption was 55,637,080 kWh excluding housing and
Fentress Air Field. Attachment 30, FY98 NAS Oceana Electricity Use by
Major Base Functions, uses a pie chart to show the percent of electrical
use by the respective commands. Training Functions (including Building
137) consumes 18% of the total electrical use at the facility. Barracks
Functions (including Building 460) consumes 11%, Administration
Functions (including Buildings 230, 232, 820 and 840) consume 6%,
Morale, Welfare and Recreation Functions (including Building 480)
consume 10%, and Supply Functions (including Building 730) consume 2% of
the total electricity. Most of the buildings at Oceana are metered for
electricity.

[Steam]{.underline}

Steam and condensate is metered only at the steam plant. Oceana
generated 191,425 MBTU (million Btu) of steam in FY97. The steam is
charged to buildings by an allocation program which is based on a
perimeter/volume ratio factor.

[Natural Gas and Fuel Oil]{.underline}

The steam plant uses natural gas-fired and oil-fired boilers for steam
generation. The steam plant at Oceana burned 207,630 Mcf of natural gas
and purchased 912,096 gallons of fuel oil #5 in FY97.

[Domestic Water and Sewage]{.underline}

The City of Norfolk provides water service to NAS Oceana. Oceana used
72,144 kgals in FY97. NAS Oceana also used 75,853 kgals of sewage
service in FY97.

### **1.6.2 Little Creek** {#little-creek .unnumbered}

The total cost of energy delivered to Little Creek was \$12.5 million in
FY96. This includes PWC costs for electricity procurement and
distribution, production and distribution of steam, and the purchase of
natural gas. Attachment 40, NAB Little Creek Energy Vision, details the
costs of energy purchased, generated, and delivered in FY96. Of the
energy purchased, electricity was 43% of the total energy costs, gas was
3.1%, and coal was 11.5%. Steam generation was 28.9% of the energy
costs. Steam distribution and electrical distribution made up 4% and
7.7%, respectively. The administration and other costs are 1.8%, which
is the operating budget of PWC.

Overall, the Ships account for 30% of the electricity consumed and 25%
of the steam, not counting distribution costs. The steam distribution
costs are shown to be 25%, but has been reported by the site energy
manager as closer to 30%.

[Electric]{.underline}

Two main meters are located at the main substation near the steam plant.
The fiscal year 1997 energy consumption was 127,033,000 kWh.

[Steam]{.underline}

Steam is metered only at the steam plant and a few larger tenant
buildings. The steam plant uses coal-fired boilers for steam generation.
Little Creek exported 420,505 MBtu of steam in FY97.

[Natural Gas]{.underline}

Natural gas is used for heating and appliances in housing and other
buildings located in reimbursable areas (where natural gas is metered).
Little Creek purchased 75,119 MBtu in FY97.

[Domestic Water and Sewage]{.underline}

The City of Norfolk provides the water used to serve NAB Little Creek.
Little Creek purchased 411,730 kgals of water in FY97. NAB Little Creek
also used 434,428 kgals of sewage service in FY97.

[Coal]{.underline}

The steam plant uses coal-fired boilers for steam generation. Steam is
used for space heating and hot water generation in the ships and
commercial facilities. Little Creek consumed 22,510 tons of coal in
FY97.

[Fuel Oil]{.underline}

One small boiler uses fuel oil. The command associated with this boiler
has a contract with a local supplier. The fuel oil consumption is not
tracked and is not a concern for this site data package.

The Energy Manager reported fuel oil is seldom used as a back-up for the
steam plant coal-fired boilers. Thus, this fuel consumption is also not
considered for this site data package.

Section 2

Facility: Energy Conservation Measures

# 2.0 Facility: Energy Conservation Measures {#facility-energy-conservation-measures .unnumbered}

## 2.1 Technology Categories {#technology-categories .unnumbered}

The sixteen buildings selected for energy improvements are summarized in
Table 2A. Technology categories for which energy conservation measures
(ECMs) can be proposed are summarized in this table as well.

Work proposed under this solicitation shall be centered on one or more
members of the family of proven geothermal heat pump (GHP) systems. ECMs
in associated technology categories are also allowed when implemented in
the same buildings with the GHPs. Such ECMs must result in a decrease in
the required GHP capacity and/or an increase in the overall GHP system
efficiency.

## 2.2 ECM Stipulations {#ecm-stipulations .unnumbered}

At the discretion of the US Navy, select pieces of existing equipment
that will be removed and replaced with new equipment installed from this
work will remain the property of the US Navy.

Improvements to the facilities will also need to be documented with an
environmental compliance plan.

## 3.1 Naval Air Station Oceana  {#naval-air-station-oceana .unnumbered}

### **3.1.1 Building 137** {#building-137 .unnumbered}

Building 137, the Strike Weapons and Tactics School, is a 41,950
square-foot, two-story, masonry building constructed in 1990. Security
is an issue in this building. Half of the building consists of two
stories with offices, classrooms, and an auditorium. The other half
consists of two large hangar bays.

The exterior walls are constructed of two-inch, pre-fabricated,
insulated metal panels on 1\" furring channels and eight-inch concrete
masonry blocks. The concrete floor slab on grade has a vapor barrier and
perimeter insulation. The second floor has a three-inch concrete slab.
The metal roof deck supports a single ply membrane roofing system. The
rigid insulation is isocyanurate, 3.4 inches thick, manufactured by NRG
Energy One. The roofing membrane is 0.75 inches thick of CSPE Hypalon.
The suspended acoustical ceiling on the first and second floors is eight
feet high, with the exception of the reception and security areas at 10
feet high, and a few classrooms and simulator labs at 9 and 10 feet.

Windows in the Reception Area are anodized-aluminum framed, insulated
storefront windows. These are the only windows in this building.
Personnel doors are insulated metal doors. Hangar bay doors are
insulated at R-11.

The western hangar is used for instruction or training. The eastern
hangar is usually empty and unheated.

The offices operate 6am to 5pm Monday through Friday. The training
program includes classroom instruction for five days a week, 8am to 4pm,
and hands on training in the hangar areas five days a week, 7am to 4pm.
Courses vary in length but may average two or three months. Courses are
held throughout the year. There are approximately 70 personnel in the
building on a regular basis and up to 150 persons during peak training
periods. Twice a quarter, night classes are conducted for five days
until midnight.

Building personnel report plans for a new addition to the building to
include another hangar. Approximately 28,000 square feet will be added
to the west side of the existing building.

Building 137 is located near Solid Waste Management Units (SWMU) and
have documented areas of groundwater and potential soil contamination.
Special contract provisions may be required for excavation and
subsurface drilling activities (see Attachment 51).

### **3.1.2 Building 230** {#building-230 .unnumbered}

Building 230, Commanding Officer and Administration, is a 22,302
square-foot, two-story, masonry building. The walls are 10-inch thick
concrete. Some areas of the building also have plywood paneling. The
windows are double paned, but the installation is very poor. Large gaps
exist between sashes and frames resulting in considerable leakage.

Offices for administration, manpower, legal, payroll, fleet sources,
comptroller, safety personnel, and career counseling are the main
functions. One area is used as a reproduction area with several large
copy machines. The offices contain traditional office equipment. A
vending area on the first floor has two soda machines, a snack machine,
and one refrigerated snack machine. The base\'s main station quarterdeck
is located in the front reception area of the building. Any problems
occurring at the bases are coordinated through the quarterdeck.

The office areas operate 7am to 5pm Monday through Friday. There are
approximately 52 personnel in the building. The quarterdeck is the front
reception area of the building and operates 24 hours every day. Three
people are stationed in the quarterdeck at all times, but two people
usually stay at the building while the other makes rounds during the
shifts.

### **3.1.3 Building 232** {#building-232 .unnumbered}

Building 232 is a 7,909 square foot concrete structure. The building has
two distinct purposes. The west half of the building is the Base
Telecommunications (also known as the telephone exchange) and the east
half of the building is the Disaster Control Center (also known as the
Hurricane Command Control).

Base Telecommunications consists of three support offices and a large
switchroom and storage area with 12-foot ceilings to house the
telecommunications equipment. The warehouse area (also called telephone
frame room on the drawings) utilizes 5% for open office space, 20% for
switchgear equipment, and 75% for general storage. The solid state
equipment generates little internal heat gain. Building personnel report
the switch gear equipment will be replaced with new equipment in fiscal
year 1998. New equipment will be installed within the year and take up
considerably less space and reject even less heat to the internal space.
Two offices (Rooms 4 and 7) were renovated from a switchboard room and
lounge area, respectively, to general office areas.

The Disaster Control Center has also been converted from the original
utilization. The area consists of several offices, a large open area for
packaging, and a berthing area. The large open area was once a computer
room (Room 20-Electronics Equipment Room) and still has the raised
floor. There are two rooms which contain bedding materials (Room
28-Instruction and Shop, and Room 27-Storage on the drawings) for
berthing should the need arise for 24 hour duty. This area also contains
a break room and kitchen area (Room 19-Destruction).

The walls are 8-inch thick concrete panels with one- to two-inches rigid
insulation and plaster. The ceiling is ten feet high with acoustical
tiles in the Disaster Control Center and the offices in Bases
Telecommunications. The ceiling is 14 feet high without a suspended
ceiling in Base

Telecommunications telephone exchange area. The roof is a concrete deck
with two-inches of insulation under a built-up roof. The building has no
windows.

Base Telecommunications offices are staffed from 7am to 5pm Monday
through Friday and the switchroom/storage area is utilized 24 hours
every day. There are five people in the Base Telecommunications office
areas and two to four people in the switchroom/storage area.

The Disaster Control Center is staffed 7am to 4pm Monday through Friday,
with potential for 24-hour operation during bad weather conditions.

## 3.3 Consumption Data {#consumption-data .unnumbered}

Building consumption data outlined in Tables 3B1, 3B2-A, and 3B3, are
based on data provided by the site\'s Energy Managers, building energy
models, and manual calculations. Monthly energy consumptions are listed
beginning with FY 1994.

Electrical energy consumption for each building can be found in Table
3B1. Building electrical consumptions for all NAS Oceana buildings
(Buildings 137 through 920) are metered values. Building electrical
consumptions for NAB Little Creek buildings are allocated values for
Buildings 2009, 2014 and 2052 and are metered for Building 2012.

The steam consumptions for each building can be found in Table 3B2-A.
Oceana allocation data are provided for fiscal year 1997 only. Little
Creek allocation data are provided for a typical year. Table 3B2-B
provides a summary of the calculated steam losses associated with the
steam distribution systems. See Section 5.2.1 for more information.

No building specific water consumption is available for NAS Oceana.
Water consumption reported for NAB Little Creek is allocated for all
four buildings as reported in Table 3B3.

### **3.3.1 Oceana Metering** {#oceana-metering .unnumbered}

Many commands and all the residences pay their utility bills to PWC
(electric and steam) and VNG (natural gas). Most of the commercial
buildings have electric meters, and none have building-level steam
meters (except for Buildings 460 and 480 which were recently installed).

The buildings with meters are read monthly and input into a database by
the Base Civil Engineering department. The tenants who pay PWC directly
use these meter readings for their billing. The remaining buildings do
not use these actual meter readings to determine their energy use, but
use allocated energy consumption. The rationale for these allocations
are based on building envelope, equipment, utilization, occupancy, and
other factors as outlined in the Utilities Target Manual (1972). See
Attachment 24 for historical heating and cooling degree-days. The steam
consumption is also based on similar allocations.

These allocations will stand until there are changes in the building
systems or floor space. At that time, the allocations will be revised.

### **3.3.2 Little Creek Metering** {#little-creek-metering .unnumbered}

At Little Creek, about 40 of the 80 commands and all the residences pay
their utility bills directly to PWC (electric and steam) and VNG
(natural gas). The base pays the remaining energy consumption bills to
PWC, without differentiation between commands or buildings. About 90% of
the facilities have electric meters and 3% have steam meters.

Buildings which do not have meters, have allocated energy usage. The
rationale for these allocations are based on building envelope,
equipment, utilization, occupancy and other factors as outlined in the
Utilities Target Manual (1972). Little Creek also bases their
allocations on degree days and compares the estimated energy
consumptions against similar buildings which are metered to establish
confidence in the estimated values.

These allocations will stand until there are changes in the building
systems or floor space. At that time, the allocations will be revised.

[HVAC]{.underline}

The building is conditioned by a heat pump loop system (HPLS). A supply
fan provides outside air to most water source heat pump units. A few
units have outside air supplied from a wall or roof opening. Chilled or
hot water circulates in the HPLS to the heat pump units. See drawings
for specific areas served by each heat pump.

The common area outside the auditorium is served by heat pump 5 and the
thermostat setting is 72 degrees Fahrenheit.

Heat pump 8 serves Room 118. The auditorium heating thermostat is set
for 72 degrees F, but is off. A switch energizes a wall mounted exhaust
fan (EF-12).

The cooling tower fans were not running during our visit, but the
cooling tower pump was operating. There are two 10-horsepower water loop
pumps, one is redundant. These pumps will provide hot or chilled water
to the heat pump loop. The motors are 85.5 and 85.6% NEMA efficiency.

Exhaust fans are located in each hangar bay, restroom area, and
projection area (auditorium and conference room).

Hot water unit heaters heat the mechanical room. Unit heater #4
thermostat set point is 68 degrees F. Two exhaust fans ventilate the
mechanical room.

One ceiling mounted hot water unit heater heats each hangar. The heater
diffuser rotates. When classes are held in the western hangar, the bay
doors are closed. The eastern hangar is not used for classes and is
usually empty and not heated.

[Steam]{.underline}

A steam converter generates hot water for use in the heat pump loop
system. The inlet steam pressure is 88 psi. The low pressure steam is 10
psi.

above, air control valves shut off steam to the converter.

### **4.2.2 Building 2012** {#building-2012-1 .unnumbered}

[Lighting]{.underline}

The Post Office, Postal Index, general offices, and NCIS use 2\' by 4\'
fixtures with various numbers of T-12 lamps. The central hallway uses
two U-tube compact fluorescent recessed can fixtures.

The post office area lighting levels averaged 80 foot-candles. The
postal index room lighting levels were 60 to 80 foot-candles. The NCIS
area lighting levels averaged 50 foot-candles. The general office areas
averaged 30 to 50 foot-candles with exceptions of 80 foot-candles in
three offices.

The upstairs fire protection offices do not use the overhead
fluorescents, but instead use domestic incandescent table lamps in two
offices. The central lobby area near the restrooms use 2\' by 2\' U-tube
two T-8 lamps. The lighting levels averaged 35 foot-candles in the
offices and restrooms, but offices with table lamps averaged 5
foot-candles.

The exit lights are incandescent.

[HVAC]{.underline}

A Carrier unit serves the Post Office with DX and electric duct heat.
Hot water baseboard convectors at the perimeter also serve the Post
Office. Occupants report the winter time comfort is marginal. It appears
there is no control over the hot water convectors. The thermostat is set
at 65 degrees F, but space appeared warmer during site visit.

Three Trane split system units with DX and steam heat coils serves the
general office. Nameplate information indicates electric resistance heat
for back up. Two units share a common return duct and outside air
intake. A Honeywell seven day timeclock is in the mechanical room, but
there are no triggers on the time clock, indicating no setbacks.

A 20-ton Trane package roof top unit with DX and steam coils serves the
NCIS area. The thermostat is set at 72 degrees F, with the cooling
thermostat off. The TCI (temperature controller indicator) is set at 70
degrees F with a night setback of 90 degrees F. It is thought that the
thermostat controls the steam coil only and is independent of the supply
fan. The supply fan is interlocked with the cooling thermostat only.
Therefore during the winter, the supply fan does not run, yet the steam
coil modulates with the demand for space heat. Occupants expressed that
during cold weather, the east end of the offices are cold and the west
end is extremely hot.

An identical 20-ton Trane package roof top unit with DX and steam coils
serves the fire protection offices on the second floor. This unit may be
oversized as a folder was installed in a supply register. The space
temperature was 76 degrees F and the thermostat was set at 54 degrees F
and was turned off.

A paper storage area adjacent to the general area utilized a device to
monitor the temperature and humidity. During the site visit, it
indicated a room temperature of 72 degrees F and 36% relative humidity.

The inaccessible portion of the second floor is believed to be attic
space and ventilated by four exhaust fans on the roof.

[DHW]{.underline}

The fire protection restroom has one 80 gallon electric domestic hot
water heater.

[Steam]{.underline}

A steam converter and direct steam are utilized.

### **4.2.3 Building 2014** {#building-2014-1 .unnumbered}

[Lighting]{.underline}

Lighting in the offices is accomplished by 2\' by 4\' fixtures each with
six T-12 fluorescent lamps. The restroom has one 2\' by 4\' fixture with
two T-12 fluorescent lamps. The average lighting level is 35
foot-candles.

There are six exterior lights (one on west side, 5 on south side) of
which 4 (on south side) were on during daylight hours.

[HVAC]{.underline}

There is one fan coil unit per office, using DX and steam coils. The
thermostat is set at 74 degrees. The restroom has one baseboard
convection unit, steam service and one exhaust fan.

[DHW]{.underline}

The restroom has one 12 gallon electric domestic hot water heater.

[Steam]{.underline}

Steam is supplied to all heating systems.

### **4.2.4 Building 2052** {#building-2052-1 .unnumbered}

[Lighting]{.underline}

Lighting in the offices, berthing, men\'s restroom and conference rooms
is accomplished by 2\' by 4\' fixtures each with four T-12 fluorescent
lamps. The women\'s restroom and vending area have two 2\' by 4\'
fixtures with two T-12 fluorescent lamps. The reception area has 2\' by
2\' U-tube fixtures with two T-8 lamps. The hallway has 2\' by 4\'
fixtures with three T-8 lamps (only area retrofitted). The exit lights
are LED.

The offices and berthing areas lighting levels were 80 to 95
foot-candles. The conference room lighting level was 100 foot-candles.
The hallway lighting level was 18 foot-candles.

[HVAC]{.underline}

There is a DX and steam evaporator unit just above the entrance door.
This unit is reported to pull outdoor air into the return air duct just
above the entrance door. Occupants report no communication between the
air handling unit and the controls. The thermostat is set at 78 degrees
for cooling and 68 degrees for heating.

Steam convectors heat the perimeter of the building.

[DHW]{.underline}

The 52 gallon, electric domestic hot water heater is reported inadequate
for the shower load.

[Steam]{.underline}

Steam is supplied to all heating systems.

### **4.2.5 Central Steam Plant** {#central-steam-plant-3 .unnumbered}

Little Creek\'s steam plant consists of three, 90,000 pounds per hour,
coal-fired boilers. There are no back-up boilers. The steam plant is
approximately 50 years old and the boilers are reported to be operating
at a reduced capacity of 70,000 pounds per hour.

The peak load at Little Creek is 130,000 MBTUs. Two boilers can handle
the load with one to operate as a spare.

The FY97 efficiency at the steam plant averaged 71.5%. Historical steam
plant efficiency is provided in Attachment 41.

There is a 90 day stockpile of coal required to be maintained year
round. During the fall, additional coal is stockpiled to account for the
greater demand during the winter months. The coal stockpile is kept to a
minimum during the summer months for safety reasons.

The steam plant manager reported that the steam is at 285 psi and 410
degrees Fahrenheit that would produce 1,204 BTU/pound. PWC calculates
the steam enthalpy of 1,000 BTU/pound to account for losses during
export.

Steam is valved off for some buildings during the summer, but the plant
must operate year round to provide heating and domestic hot water
service to the facility.

Condensate is not returned at Little Creek. Water from the City of
Norfolk is softened and used in the boilers.

The central steam plant serves NAB Little Creek buildings considered in
this site data package.

Section 5

Utility Rate Structure, Metering, and Consumption Data

# 5.0 Utility Rate Structure, Metering, and Consumption Data  {#utility-rate-structure-metering-and-consumption-data .unnumbered}

PWC procures electricity from Virginia Power. The Defense Energy Supply
Center (DESC) purchases gas, oil, and coal. Little Creek and Oceana also
procure natural gas directly from Virginia Natural Gas (VNG) for housing
and a few commercial buildings.

Table 5A1 provides the utility energy usage charges and rate schedule
summaries for both facilities. Table 5A2 provides the PWC Customer Rates
for Utilities. Table 5A3 shows the historical PWC Customer Rates for
Utilities. Table 5B1 through 5B6 shows the respective fuel PWC charges.

Public Works Center charges customers or tenants an increased rate for
electricity, steam, and domestic water to account for losses in the
distribution systems, general operations and maintenance, PWC operation
costs, and for special projects (upgrades and repairs to the systems).

**The PWC customer rates are the basis for all energy cost savings
calculations for ECMs proposed (Table 5A2).**

## 5.1 Electricity {#electricity .unnumbered}

Virginia Power supplies both Oceana and Little Creek with electricity.
Approximately 10 other bases in the Tidewater Area are consolidated with
Oceana and Little Creek to bundle the Navy\'s facilities together to
obtain the Alternate MS rate schedule. The meters from each base are
totalized for energy use and demand. These totalized values are then
applied to the rate schedule and PWC is billed for this amount.

**The PWC electricity rate of \$ 0.05640/kwh in Table 5A2 should be used
for energy savings calculations at each site.**

Details of the Virginia Power Alternate MS rate schedule are provided as
Attachment 25 for information only. Attachment 26 provides an overview
page of information used to analyze the addition or reduction of one kW
for projects. The overview shows the rates used to analyze changes to
the normal load (above baseline load), constant load (the baseline load)
and special case (night operations).

Table 5B1 provides the monthly PWC electrical billing history for Oceana
and Little Creek including energy use (kWh and MBtu), the PWC cost per
kWh, and the monthly demand (kW) for reference only (Little Creek only).
The total PWC cost, monthly averages, and averages of yearly data are
also included.

[Oceana]{.underline}

Power is supplied to Oceana from the main substation at Harper\'s Road.
This substation feeds the buildings described, while other meters serve
Fentress Air Field, stables, housing areas, and other miscellaneous
buildings associated with the base. Only the base portion of NAS Oceana
is considered for this site data package.

Meters are in place for most of Oceana\'s buildings, but are not read to
achieve billing data. Allocations provide the source for utility billing
for each building or command. The Energy

Manager's team reads these meters for historical data only. The energy
consumption and total electrical cost (at the PWC rate) for the selected
Oceana buildings are found in Table 3B.

Oceana also has diesel generators used for peak shaving in the summer
months. These are only used in the summer when Virginia Power requires
them, usually at non-simultaneous peak periods.

##### Little Creek {#little-creek-1 .unnumbered}

Power is supplied to Little Creek from a main substation. A distribution
charge is assessed. Submeters measure electricity to different areas of
the base. The Ships area has one of several submeters. Electrical
consumption for NAB, Supply Area, and 50/50 O Club is metered.

Meters are in place for some of Little Creek\'s buildings. For the
selected buildings, only Buildings 2009 and 2012 have meters which are
read. Building 2052 has a meter, but it is not read for billing. An
estimation is used. Building 2014 does not have a meter, and its
consumption is estimated. Estimations of energy consumption are based on
degree-days, square-footage of the building, and comparisons to similar
metered buildings. See Attachment 37 for predicted FY98 electricity
consumptions for each building at the PWC Rates. See Table 3B for
typical energy use for Buildings 2009, 2014, and 2052 and three years
electrical consumption for Building 2012. A notation of \'M\' represents
a \'metered\' value and \'E\' represents an \'estimated\' value.

Attachment 34 is represented in Table 5B1 for the PWC customer rates.
Attachment 35 provides the electrical use in kWh at the utility rate.
Attachment 35 shows an annual penalty for FY96, which is no longer
relevant. Averages listed are for internal use only. Note the billing
cycles differ between Attachments 34 and 35.

Little Creek has diesel generators used for peak shaving in the summer
months. These are only used when Virginia Power requires them, usually
at non-simultaneous peak periods.

## 5.2 Steam {#steam .unnumbered}

Both sites utilize underground and above ground steam distribution
systems. Attachments 20 and 21 show the steam distribution systems for
Oceana and Little Creek, respectively.

PWC considers the type of fuel or fuels used at a site to generate a
basic steam rate unique for each site. For Oceana, natural gas is the
main fuel for generating steam. Natural gas is an interruptible fuel
source and fuel oil is the backup fuel. Considering this, PWC develops
the steam rate based on the dual fuel capabilities. Steam generation is
charged to Oceana based on this unique rate. Little Creek uses only coal
fired boilers at the central steam plant and is charged the unique rate
for 'clean steam'. The Little Creek Energy Manager also reports the
steam rates are based on a regional rate.

The PWC steam rates in Table 5A2 should be used for energy savings
calculations at each site. Oceana uses general steam at \$12.22 per MBTU
for FY98. Little Creek uses clean steam at \$13.16 per MBTU for FY98.

Table 5B2 provides the monthly PWC steam billing history for Oceana and
Little Creek including the energy use (MBtu), PWC cost per MBtu, PWC
total cost, monthly averages, and averages of yearly data. Steam plant
efficiency is also provided for FY98 for Little Creek.

[Oceana]{.underline}

Steam is metered at the steam plant. A water meter at the steam plant
measures the condensate return. Differences in the meter readings are
allocated throughout the base as distribution losses.

There are only three steam meters which meter steam at a building or
branch level. These three new meters have recently been installed for
the branches to Buildings 137, 230 and 232 (Meter 1), to Building 460
(Meter 2), and to Building 480 (includes Lifeguard/Cashier Office and
Pool Snack Bar) (Meter 3). Weekly data collection has just begun.

To date, no attempt has been made to determine where steam is being used
other than for those who pay PWC directly for their steam use. Oceana
pays the difference of the total steam produced, minus the tenant
payments. Total estimated steam consumption for FY97 for the selected
buildings is found in Attachment 33.

PWC will estimate the building, or part of a building, steam consumption
when the tenant pays PWC directly for their utilities.

##### Little Creek {#little-creek-2 .unnumbered}

Steam export is metered at the steam plant. A distribution charge is
assessed. Condensate is not metered nor returned to the steam plant.

There are a few submeters to measure steam to limited areas of the base.
The Ships area (Piers) is one of several submeters. Steam consumptions
for NAB and Supply Areas are allocated from steam plant export minus 20%
distribution losses.

Steam consumption at individual buildings is allocated from the
remaining steam generated (the amount of steam which is not submetered)
based on heating degree-days, and the volume of the building. See
Attachment 23 for historical heating and cooling degree-days. The Energy
Manager is confident in the building steam usage as comparisons to
similar metered buildings provide the rationale for the estimations.
Estimated steam consumption for the selected buildings for FY98 can be
found in Attachment 37.

Little Creek steam plant efficiency for FY94 through partial FY98 is
provided in Attachment 41.

### **5.2.1 Steam and Condensate Distribution Losses**  {#steam-and-condensate-distribution-losses .unnumbered}

Pipe sizes and run lengths are taken from Attachments 20 and 21 to
determine the annual heat loss per linear foot (MBtu/lf) for both sites.
LANTDIV has provided a list of heat loss unit factors and calculations
for steam and condensate piping configurations and sizes (see Attachment
42). These factors are directly associated with Oceana, but should also
be used for Little Creek.

A summary of building steam distribution system heat loss calculations
is provided in Attachment 43. The heat loss in considered extra steam
the steam plant must produce to get the delivered amount of steam to the
buildings.

Table 3B2-B provides the total linear foot per building of steam or
condensate lines and the sum of the total loss per year (MBtu/yr) of
each building.

[Oceana]{.underline}

Oceana utilizes the heat loss calculations directly. Steam may be valved
off at certain buildings or mains. No additional charges are assessed to
the customer for distribution losses.

[Little Creek]{.underline}

At Little Creek, all buildings using steam are assessed an undetermined
losses charge of approximately 20% -30% in the winter months of November
through April. Steam is valved off in the summer, where applicable, at
the building or intersection of distribution system lines. Buildings
which utilize steam all year (i.e. steam converter for domestic water
heater) may accrue an increased distribution charge of approximately 50%
for undetermined losses in the system.

Attachment 49 shows the priorities at Little Creek for demolition of
certain buildings. This can be used the develop project phasing to
schedule the removal of the selected buildings from the steam lines
without leaving an active building without steam service.

## 5.3 Domestic Water and Sewage {#domestic-water-and-sewage .unnumbered}

Both sites utilize domestic water from the City of Norfolk. PWC also
adjusts this rate to account for PWC operations, maintenance, and line
losses.

The rate structures for domestic water and sewage are outlined in Table
5A1 for the City of Norfolk rate and Table 5A2 for the PWC rate. Both
rates are a based on a dollar per gallon charge.

**The PWC rate of \$4.15 per thousand gallons of domestic water and
\$3.20 per thousand gallons of sewage should be used as the basis for
energy saving calculations**.

Table 5B3 provides the monthly PWC domestic water billing history for
Oceana and Little Creek including water use (kgals), PWC cost per kgals,
PWC total cost, monthly averages, and averages of yearly data. Oceana
data are divided between the base proper, housing, and Fentress Air
Field. Only the base is considered for this site data package. Energy
usage in ccf and demand (kgal/hr) is also provided for Little Creek.
Sewage use is not reported in Table 5B3.

Water consumption and sewage use for Oceana and Little Creek are found
in Attachments 31 and 34, respectively. Attachment 36 also provides
water consumption for Little Creek, but does so on a different billing
cycle (Attachment 34 is based on mid-month to mid-month, Attachment 36
is based on whole months). Attachment 36 shows a rate rebate from the
City of Norfolk during FY96.

## 5.4 Natural Gas {#natural-gas .unnumbered}

The rate structure for natural gas is outlined in Tables 5A1 and 5A2 for
the DESC and PWC respectively. The basic charges for the DESC rate has
the following components:

\- Monthly service charge

\- Energy/transport charge in \$/Mcf

-   Cost of gas in \$/Mcf

-   Prepaid gas Mcf

The site orders natural gas from PWC on a monthly basis. PWC obtains
bids for natural gas supply. If this rate is acceptable, there is a cost
for the gas per decatherm and a transportation cost per Mcf. This is
called direct sales.

Another method is to obtain gas service from a local gas company. The
spot market charges a cost per Mcf, which includes transportation costs.

The pre-paid volume may be \'banked\' for later use. It is excess gas
purchased, but not burned.

PWC converts the natural gas rate and other secondary fuels to a general
steam rate, which includes charges to account for the large losses
incurred by the extensive steam distribution system. PWC charges this
steam rate to its tenants.

**The PWC steam rates in Table 5A2 should be used for energy savings
calculations at each site.** **The natural gas rate is provided for
information only.**

Table 5B4 provides the monthly PWC natural gas consumption for Oceana
and Little Creek including energy use (decatherms, MBtu, and ccf) , PWC
cost per ccf, PWC total cost, monthly averages, and averages of yearly
data. Both facilities are charged based on the steam usage, not the
natural gas consumption directly. This is included for information only.

[Oceana]{.underline}

Oceana uses interruptible natural gas as the primary fuel to generate
steam. Oceana also uses firm natural gas for radiant heating in Hangar
200, but this is not considered part of the site data package. Housing
uses firm natural gas, but housing is no longer part of Oceana (as of
FY97) and is not considered part of the site data package. Fentress Air
Field is also not considered part of the site data package.

Projects are in development to convert various buildings to natural gas
as a part of the Energy Vision to decentralize the steam distribution
system.

##### 

##### Little Creek

Little Creek purchases firm natural gas and consumed 13,383 ccf in FY97
for the base. Housing, a blast/paint facility, the galley (DHW only), a
few clubs, the commissary, and the clinic purchased 52,350 ccf of
natural gas from Little Creek for space heating and domestic hot water.
Buildings on natural gas are billed directly from VNG. See Attachment 34
for break-down of tenants and consumptions.

The selected buildings at Little Creek do not utilize natural gas. Gas
consumption for individual buildings will not be discussed further.

Natural gas consumption is expected to increase as the coal heating
system is replaced with a natural gas system in the next ten years.

## 5.5 Coal

The rate structure for coal outlined in Table 5A5 is a basic dollar per
ton charge developed by DESC.

**The PWC steam rates in Table 5A2 should be used for energy savings
calculations at each site.** **The coal rate is provided for information
only.**

Table 5B5 provides the yearly PWC coal consumption history for NAB
Little Creek including tons of coal burned, steam generated (pounds per
year), steam plant efficiency, PWC cost per ton, PWC total cost, and the
annual yearly cost. NAS Oceana does not use coal. Little Creek is
charged based on the steam usage, not the coal consumption directly.
This is included for information only.

[Oceana]{.underline}

Oceana does not use coal.

##### Little Creek

Little Creek uses coal to generate steam for space heating and hot water
for the ships and commercial facilities on shore.

Natural gas will replace coal as the primary fuel for Little Creek in
the next ten years. The coal handling infrastructure will remain for
fuel flexibility.

## 5.6 Fuel Oil 

The rate structure for fuel oil #4 and #5 outlined in Table 5A6 is a
basic dollar per gallon charge, which is a stock price developed by
DESC. The stock price includes the cost of the oil delivered to the tank
plus overhead of DESC.

**The PWC steam rates in Table 5A2 should be used for energy savings
calculations at each site.** **The fuel oil rate is provided for
information only.**

Fuel oil #4 is a blend of #6 fuel oil and #2 to obtain a certain sulfur
content which meets acceptable emissions requirements. This blending
method is approximately \$0.30 per gallon less expensive than #2 fuel
oil.

Table 5B6 provides the yearly PWC fuel oil #4 consumption history for
NAS Oceana including gallons of fuel burned, steam generated (MBtu), PWC
cost per gallon, PWC total cost, and the annual yearly cost. NAB Little
Creek does not use fuel oil except for the single boiler, which is not
tracked. Oceana is charged based on the steam usage, not the coal
consumption directly. This is included for information only.

[Oceana]{.underline}

Oceana uses fuel oil as a back-up for natural gas for the three 60,000
pound per hour boilers (Boilers #1, #2, and #3 are dual fuel boilers).
Boiler #4 is an exclusively natural gas boiler. The oil is stored in
tanks and is purchased when storage is low. NAS Oceana changed to fuel
oil #5 in FY97.

Back-up and peak shaving diesel generators also use fuel oil. These are
operated only when Virginia Power requires them to run and usually at a
non-simultaneous peak time.

##### 

##### Little Creek

Little Creek has one small oil-fired boiler on the base. Due to its
small size it is not tracked by the Energy Manager and is not considered
for the site data package. The Energy Manager suspects the fuel oil is
supplied directly from a supply contract with the respective command.

The peak shaving diesel generators also use fuel oil. These are operated
only when Virginia Power requires them to run and usually at a
non-simultaneous peak time. The diesel generators are not considered for
the site data package.

Facility, Buildings and Systems:

Maintenance Costs

# 6.0 Facility, Buildings and Systems: 

# Maintenance Activities and Associated Costs

## 6.1 General Maintenance

### **6.1.1 Oceana**

Oceana has a very limited preventive maintenance (PM) program. This is
mostly limited to filter change outs, chemical treatment of the chilled
water system, and specific equipment considered essential to the
operation of the base. Other work-related tasks are mostly repair work.
Table 6A shows the FY97 summary of planned projects, emergency service
and recurring maintenance costs. Maintenance efforts are to become the
responsibility of the ESCO.

Oceana also has a \'Self-Help\' program in which building occupants can
replace or improve the building without PWC assistance or notification.
Replacement of lighting fixtures and lamps, construction of partitioned
walls and installation of addition wall receptacles are examples. In one
case, the additional wall receptacles has led to the replacement of a
transformer to accommodate the new, larger power demand for the
building. Drawings are not usually updated to reflect changes. These
activities are not tracked for records. Maintenance efforts are to
become the responsibility of the ESCO.

### **6.1.2 Little Creek**

Little Creek has a preventative maintenance program. Table 6B shows the
FY97 summary of maintenance costs for Buildings 2009, 2012, 2014 and
2052. These records include various types of maintenance and projects
concerning the buildings, material and labor costs.

Little Creek has a reported \$35 per labor hour rate. Work that is
completed in less than 15 minutes is not usually tracked. Codes on
Maintenance records are:

> E/S is emergency service
>
> Scheduled PM - routine preventative maintenance
>
> Repair tickets are non-recurring work
>
> Active work is pending funding
>
> History is completed work.

Maintenance efforts are to become the responsibility of the ESCO.

Attachment 50, Little Creek\'s Future Projects and Status, shows the
site\'s efforts to reduce energy consumption.

## 6.2 Steam and Condensate Maintenance Costs

At NAS Oceana, maintenance costs for steam and condensate piping has
been estimated over a three year period to average approximately
\$561,546 per year. Considering Oceana has 38,000 feet of steam and
38,000 feet of condensate lines, the average maintenance cost is
approximately \$7.39 per linear foot per year. PWC agrees that this cost
is representative of maintenance costs that will accrue as a result of
any eliminated steam distribution system lines. PWC also agrees this
maintenance cost will be acceptable for calculating the steam and
condensate line maintenance costs savings for NAB Little Creek.

Selected buildings at Oceana and Little Creek have a combined 16,168
linear feet of distribution lines. This is shown in Table 6C.

Maintenance of the steam and condensate systems does not include steam
trap inspections.
