What is TAP

DOE’s Technical Assistance Program (TAP) supports the Energy Efficiency and Conservation Block Grant Program (EECBG) and the State Energy Program (SEP) by providing state, local, and tribal officials the tools and resources needed to implement successful and sustainable clean energy programs.

How Can TAP Help You

Topics include – Energy efficiency and renewable energy technologies Program design and implementation Financing Performance contracting State and local capacity building

TAP offers – One-on-one assistance Extensive online library, including – Webinars Events Calendar TAP Blog Best practices and project resources Facilitation of peer exchange

The TAP Blog

Access the TAP Blog! http://www.eereblogs.energy.gov/tap/

Provides a platform for state, local, and tribal government officials and DOE’s network of technical and programmatic experts to connect and share best practices on a variety of topics.

M&V Background Energy Savings M&V M&V Methods The M&V Plan M&V Report

M&V Background

Purpose of (M&V)

• Measurement and Verification (M&V) is the process used to evaluate performance of an energy savings project to support a guarantee of performance from an Energy Services Company (ESCO) A performance guarantee allows a building owner to invest in an energy savings project by providing confidence that the investor will either achieve a desired level of savings OR recover a shortfall for underperformance

Risk and M&V

An ESCO guarantees performance it can control – that rarely covers all risks in a project • An effective M&V plan shares risks between the owner and the ESCO: Risk of operating a facility is usually borne by the owner Equipment performance is usually covered by the ESCO Maintenance to ensure savings may be taken on by ESCO and/or owner Market price for energy can rarely be underwritten by the ESCO

THE EARLY DAYS • Shared Savings • ESCO direct Financing

M&V Background

PRESENT DAY • Efficiency Valuation Organization (EVO) • 14 years of

International Performance Measurement and Verification Protocol • Universally accepted

M&V Background cont’d.

Energy Savings M&V

Energy Savings M&V

• Establish energy usage baseline • Establish baseline adjustment procedures • Determine IPMVP M&V method for each energy conservation measure (ECM): ? Method A: Retrofit isolation – key parameter ? Method B: Retrofit isolation – all parameters ? Method C: Whole facility – continuous measurement ? Method D: Calibrated Simulation – engineering modeling • Stipulated savings

Energy Use Baseline

• Identify baseline period • Baseline energy consumption and demand data • Independent variables coinciding with energy data • Static data coinciding with energy data Witnessing by client is important

Baseline Adjustments and Energy Savings

• Routine Adjustments Weather Occupancy Operating hours Temperature settings • Non ­ Routine Adjustments ? New equipment ? Changes in use of space e.g. office to lab space ? Demolition ? Add cooled/heated space previously not cooled/heated • Energy savings = adjusted baseline – actual usage

IPMVP Method A

Method A: Retrofit Isolation – Key Parameter Measurement Short term or continuous measurement of key operating parameters: parameters not measured are estimated Example: lighting retrofit – short­term measurement – operating hours are estimated (agreed to) or measured in the audit phase

IPMVP Method B

Method B: Retrofit Isolation – All parameter Measurement Short­term or continuous measurement of all parameters Example: Lighting retrofit – continuous measurement of power, lights­on time and room occupancy

IPMVP Method C

Method C: Whole Facility Measurement Continuous Measurement of the whole facility’s energy use Example: Building with several ECMs and expected savings are above 10% of total baseline usage. Interaction of ECMs is difficult to determine

IPMVP Method D

Method D: Calibrated Simulation Savings are determined through simulation of the energy use of the whole facility, calibrated against the utility bills. Example: Facility with multiple ECMs where no utility meter was available during the baseline period

Stipulated Savings

Stipulated savings: ? Not measured ? Small compared to overall savings ? Too small to cost-effectively measure ? Moves risk from ESCO to owner

The M&V Plan IF YOU DON’T UNDERSTAND IT : DON’T SIGN IT

The M&V Plan

In accordance with IPMVP 2010, the M&V plan should cover 13 specific topics: • ECM Intent • Selected IPMVP Option and Measurement Boundary • Baseline: Period, Energy and Conditions • Reporting Period • Basis for Adjustment • Analysis Procedure • Energy Prices

M&V Plan (cont’d

• Meter Specifications • Monitoring Responsibilities • Expected Accuracy • Budget • Report Format • Quality Assurance

M&V Plan (cont’d

Additional Topics ? For Method A: Justification of estimates Periodic inspections ? For Method D: Software name Input/Output data Measured data Calibration

The M&V Reconciliation Report

The M&V Reconciliation Report should include: • Energy data for the reporting period • Values of independent variables – weather, occupancy and variables that affect energy usage • Justification for corrections made to any data • Handling of bad or missing data • Agreed estimated values for Option A • Energy rates used • Details on non-routine adjustments • Computed savings in both energy units and dollars • Emissions reduction
