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

2. Alternative Technology Association Sustainable living in action

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

4. 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)

5. 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: 1.new purpose/intent 2.as part of existing operations

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

7. Site Assessments ATA undertook high level site assessments: range of types of UCA sites: 1.Commercial office 2.Church 3.Community hall 4.School 5.Aged care

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

9. But theres no money!

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

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

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

14. $$ here Or here?

15. So, what about Solar?

17. 1 st Rule of Solar PV? Energy Efficiency!!

18. 2 nd Rule of Solar PV?

19. 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

20. Thank You!
