9. Challenges
• Reliant on engagement of homeowners and
installers
• Proper monitoring equipment is expensive
• Reliable remote monitoring is a challenge
Highlevel Outcomes
• 12 month’s data to hand for most sites
• Analysis being finalised
• There is a performance gap (+/- 6-10%)
• Heat Loss Indicator (HLI)
