- Expert audits: Professional energy audits uncovered 12-35% savings potential not visible internally
- Phased rollout: Multi-site programs (Regis: 35 facilities) achieved economies of scale
- Timing strategic work: Off-season installations (Berrydale Swim School) avoided revenue loss
Common Technology Choices
- Lighting: LED conversions universal across all sectors (15-80% lighting energy reduction)
- Heating/cooling: Electric heat pumps replacing gas (4:1 efficiency gains typical)
- Motors/pumps: Variable speed drives enabling 10-20% energy savings
- Renewable energy: Solar PV most common (4–7-year payback), 100% renewable contracts for immediate Scope 2 elimination
- Monitoring: IoT sensors and telematics reducing travel emissions and improving efficiency
Business Benefits Beyond Carbon
Operational Improvements
- Reliability gains: New equipment = less downtime (HF Hand: better weld quality, De Bortoli: improved cooling capacity)
- Productivity boosts: Better lighting/heating = safer, more comfortable workplaces (Thredbo Distillery, Glen Park)
- Reduced maintenance: Modern systems need less servicing (LEDs last 10x longer, EVs have 60% fewer moving parts)
- Future-proofing: Protection from energy price volatility and carbon pricing
Market & Brand Advantages
- Customer acquisition: 8 cases explicitly noted winning new eco-conscious customers (Ross Hill Wines: "customer excitement and loyalty increased")
- B2B requirements: Meeting retailer/client sustainability mandates (Maurice Blackburn: winning government tenders)
