Energy Audit
- Analysis of utility bills for performance and dependencies
- Identification of energy saving opportunities
- Evaluate the feasibility of identified energy conservation measures including renewable energy and cogeneration projects
- Discussions with site personnel to determine problem areas, strategies used before, critical plant issues
- Prioritise systems, identifying major energy consumers
- Determine operational standards, relevant Aust Stds, customer’s own standards
- Logging of critical plant performance vs. energy consumption
- Measurement of outcomes, lighting levels, conditions in various zones, airflows etc
- Identify system losses: hot water systems, compressed air systems, etc
- Inspection of all equipment for age and condition
Recommendations
- Identify energy saving opportunities
- Seek out heat reclaim opportunities
- Demand management options
- Benchmarking of performance against similar facilities in the EOT database
- Analysis and benchmarking of results against local data and international case studies
- Desktop analysis of systems viewed during site visit
- Analysis of alternate systems
- Investigation of fundraising/grant options
(eg Co-Generation Grants, PV Grants, Renewable Energy Credits) - Report to customer on cost effective projects with capital cost and savings detailed to +/- 20%
ESCO Team
- understand their obligations
- provide all relevant information
- evaluate proposals
- establish reasonable conditions and obligations in the EPC
- understand the procurement process, DFS and EPC contracts, M&V, financing, etc
- Complete system evaluation and conservation measure design
- Source and cost all elements .. Financial evaluations, project cost offered as fixed price, turn-key delivery, guaranteed minimum savings defined
- Selection of proposed options to meet customer defined requirements
- Development of suitable Monitoring and Verification Plan
- Develop time and resource schedule for implementation
- Develop Maintenance Schedule
- Presentation, comprehensive report + verbal presentation
Integration
- Lighting (LED, T5, Lighting management)
- Gas (LPG, NG, Bio gas)
- Water (Recycle, Management)
Monitoring & Verification
- Implement M&V in accordance with agreed M&V plan
- Conduct preliminary M&V quarterly in first year to ensure savings are being achieved
- Meet at least quarterly with Customer in first year to discuss M&V and to handle any baseline alterations
- Deliver M&V Reports in accordance with plan, written and verbal, ongoing meeting with customer to ensure satisfaction with performance and to monitor baseline
- Provide ongoing support and customer training as necessary
- Tune systems as required to ensure maximum savings
Implementation
- EOT Project Manager assigned to provide single point of contact
- Design Review conducted at time of submitting Works Specification
- Co-ordinate each area of works with appropriate customer staff
- Induction of installation sub contractors to site including all OH&S and special site conditions
- Co-ordination of system commissioning and cut over
- Commissioning sign off
- System monitoring starts as per M&V Plan
- Handover of System Operation and Maintenance Manuals
- Instruction on operation and maintenance of new systems
- Staff training as required
