Section 5 Measurement & Verification

Greater Latrobe School District Investment Grade Audit Report

This section of the report provides information for the measurement and verification (M&V) of the savings associated with each of the energy conservation measures (ECMs) recommended for implementation.

Facility energy or water savings are determined by comparing the energy use before and after the installation of the facility improvement measures. The “before” case is called the baseline. The “after” case is referred to as the post-installation or performance period. Proper determination of savings includes adjusting for changes that affect energy use but that are not caused by the facility improvement measures. Such adjustments may account for differences in weather and occupancy conditions between the baseline and performance periods.

In general,

Savings = Baseline Energy Use – Post Installation Energy Use ± Baseline Adjustments

a. Approaches to Measurement & Verification

The International Measurement and Verification Protocols (IPMVP) outlines four approaches to provide suitable techniques to verify the savings associated with implementation of a FIM. An additional approach is Calculated Savings. The five M&V approaches are:

Option A – Measured Capacity

Option B – Measured Consumption

Option C – Whole Facility

Option D – Calibrated Simulation

Option E – Calculated (Stipulated)

Option

A- Measured Capacity

This approach is intended for Facility Improvement Measures where, with a one-time measurement for specific equipment or system’s instantaneous Baseline energy use, and a onetime measurement for specific equipment or system’s instantaneous post-implementation, (Post) energy use can be measured. Baseline and Post energy consumption is calculated by multiplying the measured end use instantaneous capacity (i.e., kW, Gal/hr, BTU/hr) by stipulated hours of operation for each mode of operation (i.e., hours, week, month). The calculations for energy consumption have been defined in the FIM Description Section (IV).

Option B- Measured Consumption

Greater Latrobe School District

Investment Grade Audit Report

This approach is intended for Facility Improvement Measures where continuous periodic measurements for specific equipment or systems baseline energy use, and continuous periodic measurements for that equipment or systems post-implementation, (Post) energy use can be measured. The calculations for energy consumption will be defined in this Measurement and Verification Section. Periodic inspections and consumption measurements of the equipment or systems will be necessary to verify the on-going efficient operation of the equipment and savings attainment. The predetermined schedule for data collection, evaluation, and reporting will also be defined.

Option C- Whole Facility

Savings are determined by measuring energy use at the whole facility or sub-facility level. Continuous measurements of the entire facility’s energy use are taken throughout the reporting period. Baseline and reporting period energy use will be determined by analyzing the whole facility’s utility data. Routine and non-routine adjustments will be made as required using techniques such as simple comparison or regression analysis.

Option D- Calibrated Simulation

This approach is intended for Facility Improvement Measures where the savings are determined through simulation of the energy use of components or the whole facility. The energy use simulation is calibrated with hourly or monthly utility billing data and/or end-use metering.

Option E- Calculated (Stipulated)

This approach is intended for Facility Improvement Measures where the end use capacity or operational efficiency; demand, energy consumption or power level; or manufacturer’s measurements, industry standard efficiencies or operating hours are known in advance, and used in a calculation or analysis method that will determine the outcome. Both CLIENT and CONTRACTOR agree to the inputs and outcome(s) of the analysis methodology. Based on the established analytical methodology the calculated savings will be achieved upon completion of the Facility Improvement Measures Work and that no further measurements or calculations will need to be performed.

b. M&V Option Selected for Each Energy Conservation Measure

As the master plan is finalized and scope of work for this project is finalized, Siemens will work with Greater Latrobe School District to determine which retrofit option best fits each ECM. Table 5.1 shows which option is recommended at this time for each energy conservation measure.

APPENDIX C Chilled Water System Optimization – Savings Calculation Methodology

Energy Calculation Methodology

In every Demand Flow® project, rigorous engineering analysis is performed on each subsystem in a chilled water system. These subsystems include the chillers, the chilled water pumps, the condenser water pumps, the cooling tower fans, and the air handling units (or other loads). This section will detail the calculation methodology of the current power usage of each component in the chiller plant Additionally, it will include the calculation methodology of the expected power usage of each component in the chiller plant. Lastly, it will illustrate how these numbers will be annualized to create an annual savings model for the entire system at Error! Reference source not found.

SUBSYSTEM ANALYSIS

Chillers

Current Chiller Performance

When the chiller power (kW) is not being trended by a BAS or in a chiller log, then we look for other ways to calculate the chiller power for each data point Specifically, we use trended or recorded %RLA or RLA to calculate this chiller power. This is calculated by the typical analysis of a three-phase circuit shown in the equation below:

where voltage is the calculated average voltage of all three phases of the machine, current is the calculated average amperage of all three phases, and PF is the calculated/measured power factor of the machine.

Expected Demand Flow® Chiller Performance

Due to the proprietary nature of our Demand Flow calculations, the equations used to calculate the ideal Demand Flow chiller performance cannot be shown here; however, it may be stated that the Demand Flow calculation takes into consideration the following values: the lift of the machine, the flow rates of the condenser and evaporator, the heat of compression, the refrigeration effect, the temperatures of the water entering and leaving the chiller in the condenser and evaporator, and other pertinent values. Based on the time of year, the expected Demand Flow performance can be 5 to 60% lower than the current calculated chiller power.

Chilled Water Pumps

Current Chilled Water Pump Performance

When the pumping power is not trended directly, the pumping power may be calculated in different ways depending on if the pump is currently equipped with a variable speed drive (VFD) or not. When a pump is not currently equipped with a variable speed drive, the pumping power will be calculated from a pump test performed at the pump’s typical flow. If the pump does currently have a variable speed drive and the impeller size is held constant, the pump power will be calculated with the following equation:

where 0.7457 is the conversion factor between horsepower and kilowatts, LF is the load factor of the pump, HPfull flow is the measured full flow horsepower calculated after a pump test, GPMcurrent is the measured flow at which one is calculating for power, and GPMfull flow is the flow rate at full flow corresponding to the HPfull flow Note that tests will be done to verify the integrity of the affinity law Many peer-reviewed studies have shown that the exponent may be between 2.2 and 3.0.

Expected Demand Flow® Chilled Water Pump Performance

The Siemens Demand Flow savings calculator will identify the most ideal flow rate for each pump in Demand Flow mode. The way this ideal flow rate calculation works is proprietary, but the way the power is calculated from that flow is not. Since Demand Flow will require a VFD on every chilled water pump in the system; the equation used above for the VFD case will still be used to calculate the power in Demand Flow mode. That is the following equation (restated):

where 0.7457 is the conversion factor between horsepower and kilowatts, LF is the load factor of the pump, HPfull flow is the measured full flow horsepower calculated after a pump test, GPMcurrent is the measured flow at which one is calculating for power, and GPMfull flow is the flow rate at full flow corresponding to the HPfull flow. Note that tests will be done to verify the integrity of the affinity law. Many peer-reviewed studies have shown that the exponent may be between 2.2 and 3.0.

Cooling Tower Fans

Current Cooling Tower Fan Performance

For cooling tower fans that currently operate at full speed, the power of each fan will be tested prior to the development of a finalized savings analysis to ensure accurate accountability of the energy used by the fans prior to Demand Flow.

Cooling tower fans that operate in a “two-speed” configuration and for fans that operate with a variable speed drive (VFD), the following equation will be used to calculate the power usage of the fan motor:

where kWcurrent is the instantaneous power of the cooling tower fan at the current frequency, fcurrent, LF is the load factor of the cooling tower motor, BHP@60Hz, is the calculated full speed brake horsepower of the fan, and f60 is the full speed frequency of the motor, or 60 Hz.

Expected Demand Flow® Cooling Tower Fan Performance

The expected cooling tower fan speed is calculated using Siemens Demand Flow Savings Calculator where all components of the plant are considered to identify this ideal speed. The way the speed is selected is proprietary, but the method of relating that speed to power is not In Demand Flow all cooling tower fans will be operating with a VFD (Variable Frequency Drive) Fans that operate with a VFD, the following equation will be used to calculate the power usage of the fan motor:
