Why Invest in M&V

Provide transparency to your staff, your board, and your community

Monitor systems continuously to ensure optimal performance

Verify system performance to help make good decisions in the future

5

High Level Board Questions

Are we saving the money we were supposed to?

Are the energy projects working?

6

Add Value through M&V

CBO Questions

Should we adjust our energy budget?

Should we adjust our maintenance budget?

MOT/Facilities Director Questions

Will maintenance staff need to devote more time and energy to any projects?

Are all systems operating properly?

Both

Should we use that vendor again?

7

Where do you get these answers?

Solar monitoring systems

Utility Bills and (15 minute) interval data

Accounts Receivable

Pre-construction projections and baselines

Weather data

Operational building data

Financial Performance

Bill Savings – How you WANT to calculate it:

Why doesn’t this work?

Weather, Utility Rates, Building Usage

2011 Bill (Actual) $40,000

2012 Bill (Actual) $30,000

Savings $10,000

Financial Performance

Bill Savings – How you SHOULD calculate it:

This is a harder calculation!

2012 Bill (If no solar, calculated) $42,636

2012 Bill (Actual) $30,000

Savings $12,636

14

Fremont Case Study: Solar

Figure out what your energy profile would have been

Example

– March Utility Bill: 5,000 kWh– March Solar Production: 2,000 kWh

You would have bought 7,000 kWh from the Utility if not for solar. Why is this important?

Solar Check Up

CASBO and TerraVerde are teaming up to offer a quick check-up on common performance issues with school solar projects.

Fremont Case Study: ECMs

How do we measure and verify the effects of ECMs at sites with solar?

HVAC

Window upgrades

Lighting Efficiency

21

Fremont Case Study: ECMs

ECMs such as HVAC installation and Windows upgrades have interactive effects and are evaluated as a combined measure with the help of M&V processes.

Excel based or energy model simulation (such as e-QUEST) programs are implemented to estimate energy savings

We perform power monitored (actual consumed energy) based measurement and verification (M&V) activities to estimate the energy savings realized by the installed measures

Energy models are developed with the help of the monitored power draw and the outside weather conditions, such as temperature

22

Fremont Case Study: ECMs

23

Fremont Case Study: ECMs

For Lighting ECMs we perform time series power monitoring (data collected by loggers) of retrofitted measures to quantify the energy savings estimates.

We isolate the ECM measures and collect the actual power drawn from it for a sample monitoring period

Energy models are developed with the help of monitored power drawn and the occupancy level as a dependent parameter to estimate the total lighting consumption

Excel based analysis is performed to obtain energy savings.

Prop 39 ReportingFrom the California Energy Commission (CEC) 10/27/15:

Reporting will be done using the online system scheduled to be deployed November 2nd

– On November 5, 2015, from 10 a.m. – 12:00 p.m., the Energy Commission will host a Proposition 39 (K-12) Online Reporting System Training

Reporting of each approved EEP will be required– Annual Progress Report and Final Project Completion Reports

Annual Progress Report– Will include tracking costs spent

Final Project Completion Report:– Will require updating information provided in the EEP– Will require photos of installed measures– Due within 12-15 months after all measures are completed.

CEC Communication Plan will includes:– E-mail notification to LEAs due for a report – E-mail notification directly to the LEA Authorized Representative and Project Manager– Notification on online system

Schedule:– For this first reporting cycle, LEAs must submit all reports by December 31, 2015. – In the future, annual progress reports will be required in July.

For more info, see Guidelines p.29-32: http://www.energy.ca.gov/2014publications/CEC-400-2014-022/CEC-400-2014-022-CMF.pdf

Final Project Completion Report

Public Resources Code Section 26240(b)(1-7) requires that “[t]o the extent practical, this report shall contain information on all of the following:

(1) The total final gross project cost before deducting any incentives or other grants and the percentage of total project cost derived from the Job Creation Fund.

(2) The estimated amount of energy saved, accompanied by specified energy consumption and utility bill cost data for the school or site where the project is located.

(3) The nameplate rating of new clean energy generation installed.

(4) The number of trainees.

(5) The number of direct full-time equivalent employees and the average number of months or years of utilization for each of these employees.

(6) The amount of time between awarding of the financial assistance (that is, receiving the approved energy expenditure plan award deposit) and the completion of the project or training activities.

(7) The facility’s energy intensity before and after project completion, as determined from an energy rating or benchmark system.”
