Presentation to Uniting Church in Australia SYNOD Meeting May, 2013 Energy & Carbon Reduction Opportunities
Alternative Technology Association Sustainable living in action
Publications R110 ~ 10,000 copies sold estimated 65,000 readers published since 1980 quarterly – 40,000 readers around 3,000 subscribers 17,000 distributed
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)
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
Approach Empower site mgrs & community stakeholders to take action!
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
Opportunities Lighting Space heating Water heating Insulation & draft sealing Standby loads Design choices – new buildings Bill management Solar?
Usage: 10 hrs / weekday Lifetime: > 2 years 10 year cost: $ % more expensive! Lifetime: < 10 years 10 year cost: $115 Payback: 2.3 years Energy/carbon reduction: 86%
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)
$$ here Or here?
So, what about Solar?
1 st Rule of Solar PV? Energy Efficiency!!
2 nd Rule of Solar PV?
Economics of Solar PV Current economics: 6-8 year payback on kW system, if: low export rate around 20c / kWh energy cost many energy efficiency items better than this big greenhouse benefit case by case basis
