# Executive Summary / m&v Overview & proposed savings calculations 

## 1.1 Proposed Annual Savings Overview 

The goal of this project is to achieve energy savings through upgrades
to the building's lighting, improvements to the central plant chiller,
and the addition of an energy management control system (EMCS). This
project will also result in improved lighting levels and more reliable
HVAC and central plant operation, thereby reducing maintenance costs.
Although maintenance cost savings are anticipated for this project,
payments will be based on energy cost savings only. Savings from the
energy conservation measures (ECMs) included in the project are
summarized in Table 1-1.

# Whole Project Data / Global Assumptions

## 2.1 Risk & Responsibility 

The Risk and Responsibility matrix is located in the Appendix of this
document.

## 2.2 Energy, Water, and Operations & Maintenance (O&M) Rate Data

Energy costs used to determine the value of the energy savings will be
held constant over the contract term. The rates used to determine
savings are those that the facility is paying as of January 2004. While
the energy rates could have been escalated to account for inflation, it
was decided to keep them constant over the contract term to remain
conservative. If energy prices increase, then the agency will realize
more savings than will be claimed. The agency also needs to realize that
in the unlikely event that energy prices decrease, the energy saved will
still be valued at these rates.

The Federal Building purchases both electricity and gas from Public
Service Electric & Gas (PSE&G). Electricity is provided under rate
schedule GS-1 and gas under schedule G-1. The following rates apply:

The post-installation report will be submitted within 30 days of project
completion. The Federal Building's representative will then have 30 days
to review and approve the post-installation report. (Commissioning will
be reported separately.) After receipt of the post-installation report,
GSA will issue ABC Engineering a written notification of acceptance.

The post-installation report will document any deviations from the
specified equipment, and if necessary, make recommendations for approval
of any adjustments to M&V plans specified herein. The Post-Installation
Report will follow the format and content defined for Super ESPC
projects. The specific items that will be reported are described in the
M&V plan for each ECM.

The annual report will be due within 30 days of the end of the annual
performance period. The Federal Building's representative will have 30
days to review and approve the annual report. The Annual Report will
follow the format and content defined for Super ESPC projects. The
specific items that will be reported are described in the M&V plan for
each ECM.

## 2.4 Operations, Preventive Maintenance, Repair, and Replacement Reporting Requirements

ABC Engineering will report on all maintenance work completed in the
Annual Report.

## 2.5 Construction Period Savings

No construction period savings have been claimed.

## 2.6 Status of Rebates 

No third-party rebates are available for this project.

## 2.7 Dispute Resolution

The procedures defined in this measurement and verification plan should
prevent any disputes. In the unlikely event that a dispute does arise
regarding issues such as baseline adjustments or use of measured data,
the issues will jointly reviewed and an agreeable resolution reached.

# ECM 1- Lighting M&V PLAN AND SAVINGS CALCULATION METHODS

## 3.1 Overview of ECM, M&V Plan, and Savings Calculation 

A complete retrofit of the lighting equipment in the Federal Center is
planned as a part of the ESPC agreement. The existing T-12 fluorescent
fixtures (1,745 total) will be retrofitted with more efficient
equipment, primarily T-8 lamps and electronic ballasts. Energy savings
and demand savings will result from this retrofit. An additional benefit
will be enhanced quality of lighting, as the new fixtures will provide
improved color rendering, and less flicker.

The measurement and verification plan for the lighting efficiency
retrofit at the Federal Center will follow the FEMP M&V Option A, Method
LE-A-01. The variables affecting savings from this lighting project are
fixture wattages, hours of operation, and level of coincident operation.
Fixture wattages will be determined from a standard table of wattages or
from manufacturer's data, and annual operating hours will be stipulated
based on short-term monitored data. The fixture wattage table referenced
is from a TXU Electric program[^3].

Option A has been selected for this retrofit due to the measure's
relatively small cost savings contribution of all the retrofits
installed at the Federal Center, and due to the high confidence with
which the fixture demand and operating hours may be determined.
Equipment numbers and locations will not vary, and operating hours are
not projected to change after the project is implemented.

The measurement and verification plan for this retrofit assumes:

-   Operating hours for the lighting fixtures will be the same before
    and after the equipment retrofit.

-   Fixture wattages before and after the retrofit will be determined
    from a standard table of wattages (from TXU Electric) or from
    manufacturer's data.

-   Interactive effects on heating and cooling equipment from the
    lighting retrofit will not be considered.

-   Lighting levels will not decrease as a result of the lighting
    equipment retrofit. Existing lighting levels have been recorded for
    each area and are included in the equipment inventory.

## 3.2 Energy and Water Baseline Development

During the Detailed Energy Survey, which took place during April 2003, a
comprehensive lighting audit was completed. A room-by-room inventory of
fixture counts, types, and circuits was made. This inventory of all
existing lighting equipment, including lighting levels, is provided in
the Appendices.

Seven usage groups were identified based on space functionality and
estimated annual operation hours. For usage groups that represented more
than 5% of the savings, fixtures were monitored to determine the typical
operating hours. Groups that represent less than 5% of the expected
energy savings were not metered; operating hours were determined through
observation. However, sufficient usage groups will be monitored to
account for at least 75% of the total energy savings.

During the audit, the operating hours for a sample of lighting circuits
in each usage group was measured over a three-week period. The monitored
operating hours were used to estimate the annual operating hours for
each of the seven usage groups. The estimated operating hours will be
stipulated as annual operating hours for the duration of the contract.

A sample of monitoring points for each usage group was determined by the
following procedure:

1\. Choose sample sizes such that metering precision is expected to be
20% at 80% confidence.

Estimate the sample size n for the total population of lighting circuits
using the following standard statistical equations for estimating sample
populations[^4]:

$n^{} = \frac{Z^{2}C_{v}^{2}}{p^{2}};\ n = \frac{\text{Nn}^{}}{N + n^{}}$

where: Z = 1.282 for a confidence level of 80%, p = 0.2 for a precision
level of 20%, C~v~ = the coefficient of variation, assumed to be 0.5. N
is the total population of circuits for the building, n^\*^ is the
sample size required for an infinitely large population, and n is the
sample size after correcting for a finite population.

2\. Using the demand savings and measured operating hours, estimate the
annual energy savings from each usage group,

3\. Use metered data to determine the percentage of coincident peak
operating hours, called the diversity factor.. This value was calculated
from this data to be 72% and will be used for the duration of the
contract to determine the demand cost savings.

The usage groups and metering requirements are shown in Table 3-1. The
number of samples in the exit signs and other small groups were set to
zero. The operating hours for the remaining groups were monitored for a
three-week period in April -- May 2003. The average annual operation
hours for each usage group are shown, along with the actual C~v~ of each
group. The table shows that the estimated C~v~ for the population was
reasonable.

Bobo time-of-day lighting loggers[^5] (model BOBO-L-TOU) were used to
meter run time and determine the maximum coincident percent of fixtures
operating at any one time. These lighting loggers record the time-of-day
the lights are turned on or off. The light threshold range is 10 to 300
lumens/ft^2^ (fluorescent light); the sensitivity to incandescent light
is about ten times greater. The lighting loggers record on-off times
with an accuracy of ±1 minute per week.

## 3.3 Proposed Energy & Water Savings Calculations and Methodology

The baseline and post demand for each usage group will be determined
using Equation 3-1.

Equation 3-1:

kW UsageGroup U~baseline~ = Σ~u~ (kW~baseline\ fixture~)

kW UsageGroup U~post~ = Σ~u~ (kW~post\ fixture~)

Energy (kWh) and demand (kW) savings will be calculated using Equation
3-2 and Equation 3-3, respectively.

Equation 3‑2:

kWh Savings = ∑~u~ \[ (kW UsageGroup U~baseline~ - kW UsageGroup U~post~
) x Annual Hours of Operation\]~u~

Equation 3‑3:

kW Savings = ∑~u~ \[(kW UsageGroup U~baseline~ - kW UsageGroup U~post~ )
x Diversity Factor\]

*where:*

  ------------------------ ----------------------------------------------
  kWh Savings =            Kilowatt-hour savings realized during one year
                           post-installation

  kW Savings =             Coincident kilowatt demand saving realized

  kW UsageGroup            Lighting baseline demand for usage group u
  U~baseline~ =            

  kW UsageGroup U~post~ =  Lighting demand during post-installation
                           period for usage group u

  Annual Hours of          Annual number of operating hours for the usage
  Operation=               group u

  Diversity Factor =       Maximum percent of lighting operating at one
                           time, as determined from metered data from
                           time-of-use loggers
  ------------------------ ----------------------------------------------

The annual cost savings will be determined using Equation 3-4.

Equation 3‑4:

Annual Cost Savings = \[Rate~kWh~ × kWh Savings\] + \[12 × Rate~kW~ × kW
Savings\]

where:

Rate~kWh~ = \$0.0525/kWh, and Rate~kW~ = \$8.052/kW, as detailed in
Section 2.2 Energy, Water, and Operations & Maintenance (O&M) Rate Data.

As described in the responsibility matrix, no alterations or renovations
to the office spaces are anticipated for the duration of this delivery
order. Should the GSA make any improvements, it assumes the risk that
the savings calculated by this plan may not materialize.

## 3.4 Operations and Maintenance and Other Cost Savings

O&M savings are not being claimed or documented for this project.

  ------------------- ------------- ------------ ------------ ------------ ------------ ---------------- -----------

## 3.6 Post-Installation M&V Activities

During installation of the fixtures and lamps, existing ballast and lamp
model numbers will be spot checked on the TXU Wattage table and will be
compared to the values specified for the fixture in that location. If
more than 10% of the fixtures have greater than 10% deviations from the
Wattage table values, the estimated post-installation wattage for the
usage group will be adjusted.

After the installation is completed, an as-built inventory of
post-installation lighting fixtures will be supplied, including the
lighting ballasts and lamps actually installed, and lighting
illumination levels in each area. Savings predictions will be corrected
based on as-built data and will be reported in the Post-Installation
Report.

## 3.7 Performance Period Verification Activities

Once per year, for each year of the contract, ABC Engineering will
conduct a site visit, during which the lighting system will be inspected
to verify the fixture counts and operation, and ensure that it has been
maintained and continues to have the potential to generate the expected
savings. Lighting replacement stock will be inspected during annual site
visit to ensure equipment is being properly maintained. An estimate of
energy and cost savings for the previous year will also be included.

The Annual Report will detail the results of annual inspections, noting
significant problems such as burned-out lamps and ballasts, and
deviations with the expected number of operating fixtures, etc.

# ECM 2- Emcs M&v PLAN AND SAVINGS CALCULATION METHODS

## 4.1 Overview of ECM, M&V Plan, and Savings Calculation 

A new energy management and control system (EMCS) will be installed in
the Federal Center to provide enhanced control of the facility's HVAC
systems. This system will provide energy and cost savings by providing
time of day control for the chiller, water circulation pumps and
air-handler fans.

Currently, the HVAC fans and pumps operate at constant speed under
manual control. The fan motors operate continuously, and the chiller and
pump motors run for longer than necessary. The control system will use
an "optimum start" sequence to determine the start-up time for this
equipment. This sequence will evaluate indoor and outdoor conditions and
start the equipment accordingly so that proper set-points are reached
prior to occupancy. The winter set-point (October -- April) will be 68
°F, and the summer set-point (May -- September) will be 72 °F.

The new control system will start and stop the equipment as needed,
thereby reducing operating hours, and provide savings in the form of
reduced kilowatt-hour consumption. Demand savings will not be realized
for this measure, because the reduced operation hours will take place at
night and not during daytime peak periods.

Note that the chiller savings claimed for this measure result from
reducing chiller operation at night. The savings claimed from
installation of the new chiller (ECM 3) result from reduced demand
during operation of the chiller. Care was taken to ensure that no
double-counting of savings has been included. Additionally, natural gas
savings from reduced heating are not included due to the difficulty in
quantifying these savings.

The measurement and verification plan for the EMCS installation will
follow FEMP Option B, Method GVL-B-01: generic variable load project
with continuous metering. The EMCS system will be used to record the
actual run time of the equipment during performance period.

Option B was chosen for this measure because of the concern that
post-installation motor operation hours may not turn out as estimated.
In addition, Option B was selected because the installation of the new
control system readily lends itself to ongoing measurement. The control
system can track the actual run times of equipment with great accuracy
and very little added cost.

The following assumptions are employed for this M&V plan:

-   In the absence of this project, the pump and fan performance would
    remain constant (and not degrade) at the levels measured during the
    detailed energy survey. This is a conservative estimate in that
    should motor demand levels increase, the overall effect on baseline
    energy consumption would be to increase, thus increasing the savings
    estimated for this project. The chiller performance will be based on
    the manufacturer's performance specifications for the new chiller at
    the average off-hour load and for run-times calculated from the
    chiller baseline measurements.

-   In the absence of this project, the operation schedule of the
    chiller, pump and fan motors would remain the same and baseline
    operation hours would remain constant. Facility staff indicated that
    the operation schedule had not changed for the previous 5 years.

-   The occupied hours of the facility are assumed to remain unchanged
    for the duration of the project, and are Monday -- Friday from 7:00
    AM to 7:00 PM every day.

## 4.2 Energy and Water Baseline Development

The current annual operating hours that were reported by the facility
staff are shown in Table 4-1. Cooling equipment (chiller and water
pumps) operate continuously from May through September. The hot water
pump operates continuously from October through April. The air handler
fans operate continuously year-round. There is some operation of the
cooling system and heating system during off-seasons. Because their
operation is not easily characterized during the off-season, no
estimation of savings was made for these time periods. ABC Engineering
realizes that it is forgoing some savings that could otherwise be
claimed, but believes the M&V effort to characterize the operating hours
are too expensive to justify.

Table 4‑1: Equipment Baseline Operating Hours

  --------------------------------- ---------------------- --------------
  Equipment                         Operating Period       Annual Hours

Motor kW demand is assumed to remain constant for the duration of the
contract. The nameplate data of each motor was recorded, and the power
draw from each was measured on May 1, 2003 by ABC staff, in the presence
of Mr. Handy, Federal Center Facility Manager. These values are shown in
Table 4-2 below.

  --------------------------- ----------- ---------- ---------- -----------

The chiller off-time resulting from the EMCS is considered separately,
since although the equipment is always enabled, it does not run
continuously, nor at a constant load. The off-hour savings for the
chiller due to EMCS will be based on the average measured load during
unoccupied hours during chiller baseline measurements, and the predicted
performance of the new chiller, as detailed in Section 5 of this report.

## 4.3 Proposed Energy & Water Savings Calculations and Methodology

The run-time data recorded by the EMCS equipment will be analyzed and
summarized upon receipt on a bi-monthly basis. For each motor, during
its operation period (Table 4-1), the total number of operating hours
will be determined by the summing the status data collected for each
motor, and multiplying by the data interval (15 minutes).

Annually, Equation 4-1 and Equation 4-2 will be used to calculate the
energy savings resulting from the EMCS installation for each piece of
equipment listed in Table 4-1.

Equation 4-1:

Annual kWh~saved\ motor\ i~ = kW~baseline\ motor\ i~ × ( Op.
Hours~baseline\ motor\ i~ --Op. Hours~measured\ motor\ i~ )

Equation 4-2:

Total Annual kWh~saved~ = Annual kWh~saved\ chiller~ + Annual kWh~saved~
~AHU1~+ Annual kWh~saved~ ~EX-1~ + Annual kWh~saved~ ~CHWP-1~ + Annual
kWh~saved\ CWP-1~ Annual kWh~saved~ ~HWP-1~

The operating hours for equipment with the EMCS installed are listed in
Table 4-4 below.

Cost savings will be determined using energy rates detailed in Section
2.2 Energy, Water, and Operations & Maintenance (O&M) Rate Data.

## 4.6 Post-Installation M&V Activities

The points in the new EMCS system to be monitored for use in savings
calculations are listed in Table 4-6. All of these points will be
"trended" -- meaning that there will be a time-of-day stamp associated
with each recorded point value. From this information, the total
operating hours for the year will be calculated. Temperature data will
be collected and analyzed to ensure that the operation of the control
system is as intended. A complete listing of the EMCS system parameters
will be provided in the post-installation report, including:

documentation of the actual EMCS installed, detailed sequences of
operations, as-built points list, and a summarization of the EMCS
operation features in regard to control of the chiller pump and fan
motors,

operation manuals for the EMCS and chillers.

The EMCS system will be set up to automatically write the recorded
run-time data to the dedicated control computer's hard-drive each day at
midnight. Every-other month, ABC Engineering staff will remotely
download that data for analysis and back-up purposes. The data will be
reviewed at that time to ensure the control system is operating
properly.

During the first quarter of each year (January to March) a site visit to
the Federal Center will be conducted by ABC Engineering personnel.
Activities to be conducted during this site visit include: replacement
of all batteries in control panels; verification of proper equipment
operation; and measurement of power draw of the equipment listed in
Table 4-1 to ensure that the equipment demand has not changed.

## 4.7 Performance Period Verification Activities

The equipment that was used for taking the baseline power measurements
will be used during the annual site visit to verify equipment
performance has not changed. The meter to be used is a digital
multi-meter, ACME model 40, which is calibrated by the manufacturer on a
semi-annual basis. The meter has an accuracy of [+]{.underline}0.5%. The
meter specifications are included in the Appendices

The temperature sensors that will be used will be Elite Industries
thermistor sensors. These sensors are rated at [+]{.underline}1 ^o^F
accuracy. Cut sheets are included in an Attachment to this document.

Ongoing quality assurance procedures for the metered run times of
equipment include a bi-monthly review of the data to see if it is
reasonable and corresponds to anticipated values. Raw data files will be
stored separately and made available to the Agency upon request. In the
case that some data are missing, a check for a valid reason for missing
data will be made. If the data is truly missing, then operating hours
for the period with missing data will be derived from data from a
similar period. Sources of data used to make up for missing data will be
clearly identified and will be described in the annual reports.

The Annual Report will summarizes the results of calculations that
determine the savings. Monitored data, and details of all calculations
will be provided electronically, in MS Excel spreadsheets. An example
spreadsheet format is provided in Figure 2-1.

# ECM 3 - Chiller Replacement m&v PLAN AND SAVINGS cALCULATION METHODS

## 5.1 Overview of ECM, M&V Plan, and Savings Calculations

As detailed elsewhere in this proposal, the Piscataway Federal Center is
cooled by a central chilled water plant with a 400-ton constant-speed
centrifugal chiller that is 20 years old and has experienced significant
degradation in performance. The existing chiller has a nominal rated
efficiency of 0.85 kW/ton, which is significantly poorer in comparison
with efficiencies of currently available centrifugal chillers.

As part of this ESPC project, the existing chiller will be replaced with
a new, high efficiency unit with the same capacity. The proposed chiller
will have a nominal ARI rating of 0.52 kW/ton. The cooling tower was
replaced five years ago, and will not be modified. The chilled water and
condenser water pumps will be serviced, but not replaced. No other
changes to the cooling plant will be made. Energy savings for this
measure will result from the reduction of chiller demand to provide the
same cooling as in the baseline case.

FEMP Option B, Method CH-B-02 will be used to measure and verify the
energy savings from this retrofit. This method requires metering of
chiller electric and load variables in both the baseline and
post-installation period. Baseline metering was performed over a
short-term period, and continuous metering will be done in the
post-installation period.

The purpose of collecting baseline chiller data was to develop a model
of the existing chiller's performance. This model will enable the
prediction of the baseline chiller demand from load and system operating
parameter data. Approximately one month (August 13 to September 17,
2003) of baseline metering was conducted, with enough data points
collected to successfully build the performance model.

In the post-installation period, chiller demand (kW), load data (tons),
and system operating parameters (chilled and condenser water
temperatures) will be collected continuously. The load data will be used
to determine the equivalent baseline chiller demand for the same
interval. Savings will be determined from the difference in the
calculated baseline chiller demand and the measured post-installation
chiller demand.

It is appropriate to use Option B for this project for several reasons.
There is a significant uncertainty in what the actual operating hours of
the new chiller will be, data collection is available with the use of
the new EMCS (ECM 2), and analysis of the collected data will provide a
continuous performance check on the new chiller.

This M&V plan is based on the following assumptions:

No other changes are planned to the condenser pumps, chilled water pumps
or the cooling tower.

One month of monitoring of chiller demand and load variables was
adequate to develop an accurate model of the existing chiller
performance.

The building plans no major projects, such as building additions, or
changes which would significantly alter the current building occupancy
rate, schedule, or other internal cooling loads.

5.2 Energy and Water Baseline Development

Data collection of the existing chiller's demand, entering and leaving
chilled water temperatures, and entering condenser water temperature
occurred during August and September 2003. The data was collected in
15-minute intervals using an Elite 6-channel data recorder[^6]. In order
to collect data over a full range of operating conditions (chilled and
condenser water temperatures, chiller demand) expected in the
post-installation period, the condenser and chilled water temperatures
were reset manually. Chilled water flow was measured with a portable
ultrasonic flow meter installed in the chilled water supply loop. The
data was analyzed, and an appropriate model of chiller performance was
developed, as described below. Metered data is included in the
Appendices.

The monitored data collected during the baseline period was used to
develop the following model of the existing chiller performance. Because
the performance depends on so many variables, the chiller models
specified in ASHRAE 90.1 was used as a base and customized using the
metered data. The model is based on a set of bi-quadratic and quadratic
equations, detailed in Equations 5-1, 5-2, and 5-3.

The following notations are applicable to the equations used in this
section.

CHWF Chilled water flow in gallons per minute (GPM)

ECWT Entering chilled water temperature (return temperature, °F)

LCWT Leaving chilled water temperature (supply temperature, °F)

CWT Condenser water temperature (°F) to chiller

PLR Part Load Ratio

500 Conversion from GPM to pounds per hour Btu per pound-degree
Fahrenheit

12,000 Conversion from BTUH to tons

CAP~nom~ Nominal or full-load capacity of chiller (400 tons)

kW~nom~ Nominal or full load chiller demand. The nominal kW is the
nominal rating multiplied by the nominal capacity (0.85 × 400 = 340 kW)

The maximum capacity (tons) of the chiller varies with operating
parameters, and can be determined from Equation 5-1:

Equation 5-1:

CAP~t~ = CAP~nom~\[a + b(CHWT) + c(CHWT)^2^ + d(CWT) + e(CWT)^2^ +
f(CHWT)(CWT)\]

In addition, the chiller load and current part-load ratio at any time
(T) are calculated by the following equations:

Equation 5-2:

TONS~t~ = (CHWF)(500)(ECWT -- LCWT)(1) / (12,000)

Equation 5-3:

PLR~t~ = TONS~t~ / CAP~t~

Chiller electric demand is calculated by the following equations::

Equation 5-4:

Temp~adj~ = g + h(CHWT) + i(CHWT)^2^ + j(CWT) + k(CWT)^2^ + l(CHWT)(CWT)

Equation 5-5:

PLR~adj~ = m + n(PLR~t~) + o(PLR~t~)^2^

Equation 5-6:

kW~t~ = (kW~nom~)(PLR~adj~)(Temp~adj~)

From the metered data, the coefficients a through o were determined as
listed in the table below:

  ----------- ---------- ----------- ----------- ----------- ----------- ----------
  CAP~t~      a          b           c           d           e           f

  ----------- ---------- ----------- ----------- ----------- ----------- ----------

These calculations will be executed using a spreadsheet model shown in
Section 5.7 Performance Period Verification Activities.

## 5.3 Proposed Energy & Water Savings Calculations and Methodology

The energy and demand savings will be calculated using Equation 5-7 and
Equation 3-1:, respectively.

Equation 5‑7

Energy Savings (kWh) = Σ~t~(kWh~t~, ~baseline~ --
kWh~t,\ measured,\ post~ )

= 0.25 × Σ~t~(kW~t,\ baseline~ --kW~t,measured\ post~)

Where:

kW~t,baseline~ is the demand that the baseline chiller would have used
under the load conditions encountered for 15 minute interval t in the
post-installation period, and

kW~t,\ measured,\ post~ is the measured demand of the new chiller during
15 minute interval t.

Equation 5‑8

Monthly Demand Savings (kW) = MIN(kW~t,baseline~) --
COINCIDENT(kW~t,post~)

Where:

MIN(kW~t,baseline~) is the minimum of all baseline chiller demand
predicted for each 15-minute interval in the peak period (between noon
and 6 PM weekdays, May through October) during the current month using
the model developed for the baseline chiller.

COINCIDENT(kW~t,post~) is the measured demand of the new chiller during
the interval when the predicted baseline chiller demand was at its
minimum value.

Annual cost savings will be calculated using Equation 5-9.

Equation 5‑9:

Annual Cost Savings = Energy Savings (kWh) \* Rate~kWh~ +
Σ~month~(Monthly Demand Savings \* Rate~kW~)

Where the rates are \$0.0525 per kWh, and \$8.025 per kW, as detailed in
Section 2.2 Energy, Water, and Operations & Maintenance (O&M) Rate Data.

## 5.4 Operations and Maintenance and Other Cost Savings

O&M savings of \$12,000 dollar per year apply to this ECM. These cost
savings are the result of ABC Engineering assuming the chiller
maintenance contract for the new chiller. The cost of these annual
services will be \$14,000, compared to the existing contract for
\$26,000.

  ------------------- ------------- ------------- -------------- ------------ ------------ ---------------- -----------

## 5.6 Post-Installation M&V Activities

After the new chiller has been installed and commissioned, ABC
Engineering and Federal Center representatives will conduct a
post-installation inspection to verify that the chiller installed is
consistent with what was proposed and has the potential to generate the
cost savings predicted. ABC Engineering will provide a post-installation
report detailing actual equipment installed, and include manufacturer's
specifications and operating procedures, chilled water and condenser
water flows, and documentation of the chiller model number, its rated
and factory tested efficiencies (in kW/ton).

## 5.7 Performance Period Verification Activities

Post-installation monitoring of chiller demand and load variables
(entering and leaving chilled water temperatures, chilled water flow
rate, condenser water temperature) will be conducted for the entire
contract period. This monitoring will be accomplished using the new
building energy management and control system (EMCS). The EMCS will log
and time-stamp the data at 15-minute intervals, saving the data weekly
to disk. ABC Engineering will remotely download this data on a
bi-monthly basis for back up and quality control. In the event that
there is a significant gap in the data due to a sensor or other failure,
the process to replace the missing data with interpolated or averaged
data will be clearly documented.

Using the monitored post-installation data, collected as described
above, the baseline energy use will be computed using the model
developed from the monitored baseline data. The new chiller's
performance will be compared to the manufacturers' rated performance
annually to ensure that the chiller is operating as expected. Some
chiller performance degradation is expected over the course of the
delivery order contract (5 years), which has been considered in
determining the expected energy savings and the annual contract
payments. If substantial equipment degradation occurs, the Agency will
be responsible for taking the necessary maintenance actions to restore
the chiller performance.

In the event of an unseasonably mild summer or change to the facility
that decreases cooling load, the savings claimed will be based on a
minimum cooling load of six hundred thousand ton-hours.

[Chiller demand]{.underline}: The chiller demand will be monitored using
solid core current transducers and voltage leads connected to each leg
of the chiller's 3-phase circuit. All leads will be installed at the
time of EMCS installation. These transducers will be installed on
breakers 1, 3 and 5 (the A, B and C phases) of switch-gear SW-1.
Calibration of these sensors will be accomplished using an ACME true RMS
kW meter. Calibration of this parameter will be carried out once per
year.

[Chilled water flow]{.underline}: Chilled water flow will also be
monitored through the EMCS. At the time of chiller installation, an ACME
inline flow meter will be installed in the chilled water loop. The flow
meter is specified by the manufacturer to have an accuracy of ± 10%. The
chilled water flow will be verified bi-monthly by downloading and
checking data to identify sensors that have fallen out of calibration or
to determine whether pump or chiller performance has degraded.

[Condenser and chilled water temperatures]{.underline}: Water
temperature sensors will be the insertion type, installed in new
thermo-wells for both the condenser and chilled water temperatures. The
sensors used will be ACME 2-wire, 1,000 OHM platinum RTDs paired with a
4-20 mA transmitter. The combined unit(s) will have an operating range
of 20-120 °F with an accuracy of ±0.50 °F. An annual field check of
calibration will be conducted using the analog thermometers installed in
the supply and condenser water lines.

In addition to the calibration and testing procedures outlined above,
all components will be tested and evaluated once each contract year.
Also, the EMCS will continuously monitor the calculated kW/ton of the
new chiller and issue an alarm when this value moves outside the
expected range (0.40 - 1.10 kW/ton).

The data will be collected using quality control procedures for checking
the measurements for reasonableness. Any and all missing intervals will
be replaced either by interpolation or use of average values. Such data
will be described in annual reports.

The Annual Report will summarize the calculated savings for the past
year. Savings calculations will also be provided electronically, in MS
Excel spreadsheets. All calculations will follow the procedure described
in this M&V plan. In addition to the reports, all monitored data will be
submitted in electronic format.

The spreadsheet will show all intermediate steps in calculating baseline
chiller kW, and show how energy savings will be determined. A sample
spreadsheet format is provided in Figure 2-2, where variable names are
described in the chiller M&V Plan.
