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/intent2. 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 office2. Church3. Community hall4. School5. Aged care

Opportunities

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

But there’s no money!

Halogen Downlight50 wattPrice: $1.00

LED Replacement7 watt

Price: $70.00

Usage: 10 hrs / weekdayLifetime: > 2 years10 year cost: $330286% more expensive!

Lifetime: < 10 years10 year cost: $115Payback: 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?

1st Rule of Solar PV?

Energy Efficiency!!

2nd Rule of Solar PV?

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

Thank You!
