  1. Energy & Carbon Reduction Opportunities Presentation to Uniting Church in Australia SYNOD Meeting May, 2013

  2. Publications • R110 ~ 10,000 copies sold • estimated 65,000 readers • published since 1980 • quarterly – 40,000 readers • around 3,000 subscribers • 17,000 distributed

  3. Context • 2011 SYNOD Resolution: • 20% reduction of energy / emissions by 2020 • all UCA assets • Energetics Report – 2011 • high level estimate of energy & emissions • aggregated estimate: +/- 40% confidence • energy & CO2 close to compliance triggers • but UCA not regulated (non-incorporated body)

  4. Objective • Progress towards 20% reduction target • report every 3 years...? • no formal measuring & reporting systems • significant amounts of data collected • No ‘centralised’ approach • reliant on activities of site mgrs/congregations/etc • 2 ways: • new purpose/intent • as part of existing operations

  5. Approach Empower site mgrs & community stakeholders to take action!

  6. Site Assessments • ATA undertook high level site assessments: • range of types of UCA sites: • Commercial office • Church • Community hall • School • Aged care

  7. Opportunities • Lighting • Space heating • Water heating • Insulation & draft sealing • Standby loads • Design choices – new buildings • Bill management • Solar?

  8. But there’s no money!

  9. LED Replacement 7 watt Price: $70.00 Halogen Downlight 50 watt Price: $1.00

  10. Lifetime: < 10 years • 10 year cost: $115 Payback: 2.3 years Energy/carbon reduction: 86% Usage: 10 hrs / weekday Lifetime: > 2 years 10 year cost: $330 286% more expensive!

  11. Gas • Split system units • both heat and cooling • high efficiency (CoP 3-5) • Typical heating source (Vic) • many UCA sites • end of asset replacement? • gas prices rising

  12. Or here? $$ here

  13. So, what about Solar?

  14. 1st Rule of Solar PV? Energy Efficiency!!

  15. 2nd Rule of Solar PV?

  16. Economics of Solar PV • Current economics: • 6-8 year payback on 1 - 20kW system, if: • low ‘export rate’ • around 20c / kWh energy cost • many energy efficiency items better than this • big greenhouse benefit • case by case basis

  17. Thank You!
