Energy for Life
Energy efficiency for service stationsMay 2013
Sustainable Efficiency…….through Objective Design
Energy for Life
Agenda
– Why the focus on energy efficiency?– International best practise– Methodology– Key elements of Energy Management– Energy Auditing– Energy efficiency interventions– Incentives, Financing & Funding
Energy for Life
Why efficiency – Landlord / Tenant?
– Oil company or Landlord – Building Value– Increased Rental potential– Enhanced rental model
– Dealer (Tenant)– Energy risk – escalating electricity prices – Long-term Profitability and Sustainability– Financing of efficiency interventions
Energy for Life
Why efficiency – SA back drop ?
– Immediate considerations: – Escalating energy prices threatening sustainability– Building Management – improve efficiency save
money– 10400XA – a requirement for refurb or new build– Property Investment - Valuations – key for future– Generator efficiency – how often is it used?– Incentives
– Eskom SOP– Green funding
Energy for Life
Why efficiency – SA back drop ?
– Up coming considerations– Carbon Tax 2015
– R120 per Ton of CO2– Example: CO2 for a Small SS 21T @ cost R2520
– Energy efficiency Tax Incentives – National Energy Act 2008 - 34– Income Tax Act 1962 - 12L– Proposed R0.45 c/kWh saved– Apply by 2015

International Best Practise
Energy for Life
Sustainable Design methodology
- First Reduce Demand – change procedure / behaviour and pro-actively manage
Demand - then look for Efficiency –
implement relevant technologies e.g. Voltage Optimisation or PC Power Management
- then look to Innovate – generate Power on site
– Solar PV or Wind
Energy for Life
Key elements of Energy Management
– Measurement and Management– Behavioural and Procedural change– Technology interventions
Energy for Life
Measurement and Management
“If you can’t measure it you can’t manage it”. Peter
Drucker
Energy for Life
Measurement and Management
– Key issues– What am I using currently? – Am I charged correctly? – Am I on the right tariff?– How effective is my savings plan?
Energy for Life
What am I using? - Benchmark analysis
– Know your benchmark
– When am I peaking (kVa)?
– Revise with targets
– Control energy usage against the benchmark
Energy for Life
Am I charged correctly? - Bill verification
– What am I consuming?– kWh– kVA
– What rate am I being charged?
– Am I being billed correctly?
Energy for Life
Am I on the right tariff? - Tariff Analysis
– Measure usage patterns
– Evaluate available tariffs
Energy for Life
How effective is my saving plan?
– Key areas– Behaviour and procedure change? –
measure the effectiveness of the changes.– Technology changes – measure the
vendor solutions for promised savings, paybacks and ROI.
Energy for Life
Cost to measure?
– On line Metering and switching– Measure 24 & control 8 points– R4500 Capital outlay – R250 per month
Energy for Life
Key elements of Energy Management
– Measurement and Management– Behavioural and Procedural change– Technology interventions
Energy for Life
Behavioural and Procedural change
₋ Observe: ₋ Opening Procedure₋ Daily Behaviour ₋ Closing Procedure
₋ Identify Opportunities₋ Implement Changes
Energy for Life
Behaviour and Procedure change
₋ 20-30% savings achievable ₋ Low cost non tech solution₋ Keys to success
₋ Training ( pocket guide and labels)₋ On going awareness (equipment labels & poster
campaign)₋ Strong management (guide & checklist)₋ Pro-active daily measurement and alerting
(metering) ₋ Staff incentivisation

B&P costs
– Small site R5605– Audit R 1500– Training R 3000– Campaign material R 1105
– Medium site R6194– Audit R 1750– Training R 3000– Campaign material R 1444
– Large site R6742– Audit R 2000– Training R 3000– Campaign material R 1742
– 4-6 months payback

Energy Auditing
– Approach– Steps in the audit process
– Establish and question the benchmark– Understand the contributors– Question design assumptions
Energy for Life
Auditing approach
₋ Once off or on-going?₋ Once off snap shot
₋ Understand contributors₋ Prioritise solution focus
₋ On going₋ Main incomer₋ Key circuit management
Energy for Life
Steps in the Process
- Detailed Audit- Establish Baseline demand- Question and Analyse the Baseline demand - Determine the Contributors - Confirm Focus areas- Identify High level solutions
- Post audit:- Prioritise, Design and Implement interventions- Implement process/behaviour change
Energy for Life
Detailed audit steps
– Behavioural and Procedural assessment– Occupancy– Light levels– Equipment inventory– Contributor measurement and analysis– Demand peak management
Energy for Life
Contributor measurement & analysis
– Measure individual circuits– Understand the impact of circuits on overall– Understand equipment impacting Peak (kVA)– Enable
– educated approach to Capex spend– accurate payback analysis

Peak Demand measurement & analysis
– Measure individual circuits as contribute to demand (kVa)
– Understand the impact of circuits on demand– Enable
– pro-active demand management– reduced demand costs
Energy for Life
Peak demand targeting
Energy for Life
Energy efficiency interventions
– Lifecycle costing approach– Maintenance costs – Energy savings– Equipment life– Eskom incentives
– Give and take– landlord/lessee & dealer
– win-win approach– sustainability of dealer
Energy for Life
Types of audits
– B&P– Walk through
– Equipment inventories– B&P– Contributor analysis– High level energy plan
– Detailed audit– Equipment inventories– B&P– Contributor analysis– Conceptual design– Detailed energy plan
