1 Guaranteeing long-term cost savings through energy efficient measures, with the option of fully funded solutions

2 What is energy performance contracting? Innovative way to implement energy saving improvements Guaranteed energy savings pay for the capital investment Client makes no upfront capital investment EPCs are without risk to the customer Energy savings guaranteed and underwritten by the ESCO It is not an asset purchase Works as a service agreement off balance sheet

3 Pay as you save model No Interventions plus energy inflation Additional cost avoidance due to energy price increase Energy & Operational Costs Baseline (typically the last 12 months consumption) Savings circa 10-30% Savings to pay for Managed Service Reduced Costs due to interventions Customer Savings Duration of EPC (Typically 7-10 years) Time (years)

4 Energy performance guarantee Formal independent Measurement and Verification (M&V) protocol ESCO assists in development of agreed building user protocol Unequivocal, underwritten fully No risk to client ESCO holds & manages the risk Open book, full disclosure

5 Typical Energy Performance Contract Process 1Identify opportunity and owner criteria Identify opportunity Develop customer base Understand customer needs Initial assessment of suitability Articulate benefits

6 Energy Performance Contract Process 2Desktop audit technical review Free desktop audit Base line consumption data Non-invasive inspections Identify likely technologies Go / No go Consult and write up results

7 Energy Performance Contract Process 3Investment Grade Proposal (IGP) Fixed price proposal Detailed design Implementation costs & schedules Go / No go Go / No go Technical assurance Determine finance source

8 Energy Performance Contract Process 4Evaluate IGP & define final service scope Secure financing Identify and guarantee savings Agree new baseline and targets Go / No go Go / No go Execute Energy Performance Contract Sign off scope and implementation

9 Energy Performance Contract Process 5Undertake interventions Supply chain in place Detailed programme Savings guarantee period begins Go / No go Integrated design and delivery Commission new systems and processes Go / No go

10 Energy Performance Contract Process 6Measurement & Verification Record consumption data IPMVP* Savings guarantee period begins Go / No go Go / No go Demonstrate achievement of new target base line Work place analysis Ongoing training & communication Consider further improvements *International performance measurement and verification protocol
