Presentation Notes

Good afternoon. This afternoon I’ll discuss the Energy Measurement and Verification revolution that has begun in industry; and how businesses in NSW can use Measurement and Verification to access the Energy Savings Scheme to lower cost of projects that increase energy productivity. These graphs demonstrate the problem that IPMVP is trying to solve… there is no “Energy Savings Meter”. Many businesses get monthly bills from their retailer, but don’t have meters installed for electricity or natural gas and so can only undertake high level analysis of energy usage. They can’t easily understand differences year on year and relative energy performance, or the impact of energy conservation measures they install. Ask attendees about their own experiences with M&V Trainer to highlight the benefits of M&V from the examples

Presentation Notes

20 yrs ago (1994) the US Govt identified massive opportunities from EE but major barrier: no consistent method to determine savings In 1996 a group of industry experts from US, Canada + Mexico published first standards Then experts from 20 countries worked on a revised version that has been internationally adopted by many countries In 2001 the protocol committee formed a non-profit (“IPMVP Inc”), then changed its name to the the Efficiency Valuation Organisation (EVO) in 2004 The International Performance Measurement and Verification Protocol (IPMVP) provides an overview of current best practice techniques available for verifying results of energy efficiency, water efficiency, and renewable energy projects.” Standardised tool to cost-effectively measure the economic and environmental benefits of energy efficiency projects.

Presentation Notes

The ESS is a white certificate scheme that commenced in 2009. This slide shows the directions of flows in money and certificates, length of arrows isn’t to scale: these depend on the contracts entered into by different parties. The ESS involves 3 parts of NSW Government, each with separate responsibilities: OEH develop the ESS, DoI administer the legislation and IPART is the scheme administrator, the Independent Pricing and Regulatory Tribunal. Your interest in the ESS will determine if you are liaising with OEH, DoI or IPART. Note the terminology confusion between RESA (Registered Energy Savings Activity) and accreditation

The measurement boundary must include all end user equipment whose energy consumption will be affected by the RESA. Could be defined by NMI and physical site boundary, or more specific to EUE. Measurement boundary should be defined to minimise interactive savings.

• Cold Storage Facility operating multiple small refrigeration systems

Savings achieved by:

• Improving part load performance:

– Variable head pressure – VSD control of screws – Evaporator VSDs

• Improving Refrigerant quality (ie: reducing contaminants eg: oil, water)

Certificate creation reduced simple payback time by 57%!


Presenter

Presentation Notes

NOTE: “Refrigerant Quality” can be controversial if not clearly defined! What this slide refers to is the presence of contaminants in the refrigerant that adversely affect the thermal properties, effectively reducing the COP of the whole system. The most common contaminants are lubricating oil leaking into refrigerants, and not being effectively removed by oil separators. And moisture leaking into some types of refrigerants, especially Ammonia systems, and not being effectively removed by dryers.

Ventilation Fan Case Study

Project Capital Cost $ 11,000 Annual Energy Savings (MWh) 148 MWh/year

Annual Energy Savings ($) $ 18,000 Simple Payback without ESC creation 0.6 years (7.2 months) Forward Creation Certificate Quantity 1,666 Forward Creation Certificate Revenue $38,300

Simple Payback with ESC creation 0.2 years (2.4 months)

• Plant workshop requiring ventilation for control of CO levels

Savings achieved by:

• Retrofitting a VSD to the existing fixed speed fan

• Control loop via CO sensors in the workshop

Small project but a big impact on simple payback due to

large certificate return.


• Split into two groups

• Discuss and identify:

– Measurement boundary – Metering involved (and the cost) – Independent variables – Measurement time periods – Expected Savings (%)

• Make sure you can justify your answers.

M&V Exercise

Project 1: Commercial building BMS & HVAC Upgrade (controls &

AHUs)

Project 2 Manufacturing site with chilled water for

processing cooling and climate control Chiller replacement (with associated

pumps)


• End Consumers and Energy Users:

– Identify and choose an ACP

– Start baseline measurements ASAP

• Consultants, Project Developers:

– Identify and choose an ACP or

– Become an ACP

• Technology & Equipment Suppliers:

– Discussions with ACPs to identify who has an accreditation for your product
