Capacity Building of Banks and Financial Institutions for Energy Efficiency Project Financing Module 5Measurement and Verification Partnership to Advance Clean Energy-Deployment (PACE-D)Technical Assistance Program
Presentation Outline • Why Measurement and Verification (M&V)? • Key Considerations in M&V • Basic Concept of M&V • M&V Methodologies • M&V Protocols • Common Issues • The M&V Document • Case Studies
Why M&V Measurement and verification: • Is needed to confirm project energy savings and validate that anticipated or guaranteed performance has been achieved • Presents common definitions, terminology and procedures for energy-efficiency projects • Improves communication and understanding among project implementing partners • Provides a risk management tool to financing entities • Minimizes disagreements and disputes • Facilitates persistence of energy savings
How much does M&V cost? • The costs of M&V depend on the energy efficiency technologies and measures to be implemented and the approach and methodology to be utilized • M&V costs 5 to 10% of project investments • Trade off between • accuracy of the M&V • cost of M&V • Simple approaches are preferred to reduce costs and minimize potential for disputes
Who Pays for M&V Costs? • If the project host conducts or engages a third party to conduct M&V, the host directly pays the M&V costs • If the ESCO conducts or engages a third party to conduct M&V, the M&V costs are part of ESCO’s costs • In either case, the M&V costs are an integral element of project cost and an allowance needs to be made in the project budget and financing plan for these costs • While the M&V is specified in the Energy Services Agreement between the ESCO and host, the lender needs to understand and approve the M&V approach and costs
IPMVP • Developed by a coalition of researchers and practitioners • Managed by independent organization (EVO) dedicated to provision of tools to quantify the results of EE projects and programs. • Provides flexible framework of M&V options that allows practitioners to craft the right M&V Plan for their project • Internationally recognized and accepted • Certification program for M&V professionals • Implemented in India by Alliance for Energy-Efficient Economy (AEEE) International Performance Measurement and Verification Protocol
M&V Training and Certification in India • First M&V Seminar Delhi April 2005, PCRA hosted for EVO • M&V Fundamentals trainings in various cities of India • Application of M&V to Government Schemes – Building Codes, PAT, DSM • CMVP Certification Training & Exams in Delhi – Nine rounds completed more than 100 professionals certified • EVO has Certified 5 Indian Trainers as CMVP Trainers • AEEE has conducted M&V Training in Manila and Bangkok • Opportunity to widen M&V capacity building to South & West Asia
M&V Approaches in IPMVP • Retrofit Isolation Methods • Option A – Partially measured or one time measurement • Option B – Longer or continuous measurements • Whole Facility Methods • Option C – Whole facility energy analysis • Option D – Computer simulation
Adjusting for Changes in Baseline Facility Use or Operating Conditions Occupancy Possible Changes in Baseline Equipment Operating Schedules Environmental Conditions Additions to Energy-Using Equipment Facility Refurbishment or Rehabilitation
Option A • Simple approach (and low cost) • Performance parameters are measured (before and after), usage parameters may be estimated • Used where the “potential to perform” needs to be verified but accurate savings estimation is not necessary • Key features • Low cost • Simple procedure • Requires agreement among parties
Option B • Under Option B, some or all parameters are measured periodically or continuously • Applicable where accurate savings estimation is necessary and long-term performance needs tracking • Reduced uncertainty, but requires more effort • Key features • “Real” M&V • Improved O&M • Ongoing Commissioning • Remote monitoring
Option C • Option C looks at energy use and cost of entire facility, not at specific equipment • Conceptually simple, may be difficult in practice • Key features: • Can consider weather, occupancy, etc. • Useful where total savings need to be valued but component savings do not • Commercial software is available that simplifies implementation • May require baseline adjustments
Option D • Option D treats building as computer model • Flexible, but requires significant effort • Applications: • New construction • Energy management & control systems • Building use changes • Building envelope modifications & additions • Uses specialized software that requires substantial experience • Requires measurements for calibration
Example of Lighting Project M&V - Option A • Baseline is 100 W light bulb and new lamp is 25 Watt compact fluorescent • Wattage verified by measurements/specifications • Assume 3,000 operating hours per year: • Previous experience • Estimate by owner • Calculated Savings are: 3,000 hr/yr * (0.1 - 0.025 kW) = 225 kWh/year
Lighting Project M&V - Option B • Install meters on lighting circuits (before lighting retrofit is implemented) • Measure consumption before and after retrofit for a specified time period • Calculate savings
Lighting Project M&V - Option C • Used when lighting is the dominant load • Document baseline utility bill • Obtain post-installation utility Bills • Calculate savings
Lighting Project -Option D • Used when interactive effects need to be estimated • Input lighting and HVAC system into simulation program. • Calibrate model and calculate pre- and post-installation lighting and interactive HVAC energy use for determining savings.
Common M&V Issues • Factors affecting saving performance • Predictability, measurability, factors such as weather, occupancy, equipment intensity, ability of EEMs to deliver savings, implementation effectiveness, occupant – operator cooperation, equipment deterioration and life • Evaluating saving uncertainty • Instrumentation error, modeling error, sampling error, planned and unplanned changes • Minimum energy Standards • Minimum operating conditions
Common M&V Issues (continued) • Energy Prices • For simplification, price is specified • Verification by a third party • Third party can resolve issues • Baseline adjustments • Routine and non-routine • Cost • Cost to owner against benefits
M&V Information Document • Project site and measures • M&V option selected - Options B or C • Details for calculations • Data collection plans • Assumptions • Energy rates • Baseline equipment and conditions • Equipment, space conditions, assumptions, energy use relative to production, adjustments – how and when
M&V Information Document (continued) 5. Post-installation equipment and conditions • Plan for defining new equipment and space conditions, assumptions and stipulations • Metering • Schedule of metering (duration/when), who will provide, data validation, sampling • Measurement and verification activities • Who conducts M&V, analysis and prepare report, quality assurance, reports defined and post installation energy use relative to production 8. Initial and annual cost
