Outline IPMVP Inc. – Organizational Issues Recent Efforts New Construction Renewable Energy Technologies Baseline Development in DR Programs Quantifying emissions reductions from EE projects

The Organization IPMVP Inc. is a non-profit organization responsible for maintaining existing and developing new protocols under the IPMVP umbrella Supported by US Department of Energy, LBNL, and Charter Members

Charter Members Bonneville Power Administration Energy Foundation Federal Energy Management Program General Services Administration NYSERDA Sacramento Municipal Utility District Southern California Gas

Mission Statement “To develop and maintain an international, consensus framework for creating measurement and verification (M&V) protocols to quantify such metrics that determine the financial value of any energy efficiency projects.”

IPMVP Sphere of Influence IPMVP Inc. Renewable Energy Tech. Energy/Water Efficiency Retrofits Performance Benchmarking of New Const. Indoor Environmental Quality Quantifying Emissions From EE Projects Baseline Determination in DR Programs

Objectives - I Maintain a stable and financially self-sustaining organization, while remaining faithful to the organization’s mission. Establish and maintain internationally accepted M&V standards for energy and water efficiency and demand reduction projects. Reach out and effectively involve the finest international talents and expertise in developing protocols and in avoiding duplicate efforts.

Objectives - II Maintain contact with practitioners and market place to ensure relevance of the protocol. Effectively disseminate the IPMVP guidelines around the world, work with our international partners to encourage the translation of the Protocol for faster and more effective adoption and application of the IPMVP concepts. Develop training and certification material to educate and train professionals in the field of measurement and verification of energy savings.

M&V of New Construction Baseline Development Basics Appropriateness of Benchmark Energy codes/standards, design standards Rigor Use appropriate M&V methods and defensible assumptions Reasonableness/Repeatability Come up with a reasonable baseline estimate with a provision to adjust based on post-construction findings

M&V of New Construction Approaches to Performance Verification Component Verification Whole Building Benchmarking Calibrated Simulation

M&V Options in New Const. M&V OptionsTypical Applications A. Partially Measured ECM Isolation Partial measurement of system energy use. Some operating parameters are stipulated. Lighting system or constant speed motors - power draw periodically measured, operating hours stipulated. B. ECM Isolation Full measurement of energy use and operating parameters of system. Variable speed control of a fan motor – Continuous measurement of energy use throughout M&V period. C. Whole Building Comparison Savings determined at whole-building level by measuring energy use at main meters or with aggregated sub-meters. Government agency wishes to determine order-of-magnitude savings level associated with a building design incentive program. D. Calibrated Simulation Savings are determined at whole-building or system level by calibrating simulated energy use to measured energy use Savings determination for the purposes of a new building performance contract, with the local energy code defining the baseline.

M&V of Renewable Energy Technology (RET) Status In Final Draft Form Before the Technical Committee What’s New Consistent With the Latest IPMVP Concepts and 2001 IPMVP Volume I Format More Examples

M&V of RET Key Issues Renewables supply energy rather than reduce the amount of energy used. M&V strategy for renewables must be able to differentiate between an energy supply and a reduction in the load. The performance of renewable energy systems is a function of environmental conditions (solar radiation and wind speed), which are outside the control of the project developers and should be accounted for.

M&V of RET Option A: Partially Measured Retrofit Isolation - It measures the ability of the system to deliver energy, capacity, and other claimed benefits and applies the measured result to an assumed set of operating conditions. Option B: Retrofit Isolation - It involves long-term measurement of energy delivery directly by metering the plant’s output or indirectly by determining savings based on analysis of end-use meters. Option C: Whole Building Analysis - It involves inferring savings by the statistical analysis of whole-facility energy consumption without end-use metering of the renewable energy system. Option D: Calibrated Simulation Models – It involves predicting the long-term performance of a system or whole building by calibrating a computer model based on data from a short-term test.

M&V protocol for Calculating Demand Reductions Sponsor California Energy Commission Jointly developed by Xenergy and IPMVP Analysis performed by Xenergy Review conducted by IPMVP Inc. Goal Calculation of the baseline against which reductions are calculated. Help increase participation in DR programs of small- and medium-sized customers by reducing the barriers related to inconsistency and confusion about baseline methods.

M&V protocol for Calculating Demand Reductions Criteria for a Good Baseline Method Simplicity Accuracy Minimize gaming Predictability Consistency (with other ISOs)

M&V protocol for Calculating Demand Reductions Recommendations A method that generally works well for a range of load types is the simple average of the last 10 days, by hour of the day, with additive adjustment to the 2 hours prior to the curtailment period. This method can be recommended for both weather-sensitive and non-weather-sensitive accounts, with both low and high variability, for summer and nonsummer curtailments.

Emissions Initiative In developmental stages Motivation Guarding EE community’s interests Key Issues Site Vs. Source Program Vs. Project Where IPMVP Can Make a Difference Build on the Strength of IPMVP Need for aggregation

Emissions Initiative – Proposed Strategy Illustrate candidate approaches to convert energy savings into emission credits based on the uncertainties inherent in the M&V option selected to quantify energy savings; Develop simple, practical, repeatable, and cost-effective monitoring, evaluation, and verification approaches Role of IPMVP in different trading program such as Cap and Trade, Offsets, and Set-asides. Emission factors for typical fuel burning appliances or reference to a range of resources; Link to national or state registry of emissions factors at least at an aggregate level; Better guidance for the EE community on the difficulties of off site emissions for electricity and district heat/cool; Current list of relevant environmental authorities/rule makers and their web sites; Related bibliography;
