Strategy of FirstRand Energy Management
1. Baseline of electricity spend (Oct 06 – Sep 07)
2. Target of 11% reduction in electricity use per building by 2012
3. Energy Dashboard for large buildings and Business Units
4. Collaborate Energy Saving initiatives using Best Practice
5. Identify and advise on new technology / initiatives
6. Buy-in from senior management
Why must we save electricity?
• Reduce load on the Eskom Grid
• Extend backup power supply
• Energy Conservation Scheme (ECS)
• Reputational Risk (Marketing)
• Environment
• Financially Viable

New Energy Saving Initiatives
Heat Pump Water Heaters
•
•
•
•
Vapour compression cycle, opposite of a air conditioner
Heats water up to 60 degrees
Anticipated 67% electricity saving with a payback period of 18 – 24 months
Bank City to pilot and measure Heat Pump savings, if successful, then
rollout to Group
Electricity Optimisation
•
Optimise voltage and air-conditioning
Staff awareness
•
•
A product is being piloted that creates an alert on computers when the target
of 10% saving will not be achieved
The objective of this, is for the staff to look for ways to reduce electricity
themselves
New Energy Saving Initiatives
Increase Temperature of the Air Conditioner
•
•
•
•
•
Four Merchant Place increased the temperature by two degrees for one week
Air conditioning power requirement dropped by an average of 50 kW
This is equivalent to 438 000 kWh per annum
Which is equivalent to approximately R226 000 saving per annum
Same number of complaints
IT Energy Saving Initiatives
Energy Saving Settings and Remote Shutdowns on Computers
•R100 to R250 electricity saving per computer per annum
Computer Centres
•Blade server technology consolidates servers with greater energy efficiency
in relation to processing power
•Virtualisation of computers

Energy Saving Settings and Remote Shutdown of Computers
• We are piloting two Windows based programs to identify which will be the best
program to implement across the FirstRand Group.
• Below are initial findings from a Baseline that was created before settings were
changed.
• Projected Savings extrapolated from 282 computers currently being monitored
– 327 562 kwh
– R 163 781
– 314 metric tonnes of CO2
Fairland Office Park
•
•
•
•
The furthest distance of a workstation from a perimeter window or light well is 15m
Large amount of natural light
The lighting system uses dimmable electronic control gear
Insulation from roof to wall to window and double glazing on the windows
Fairland Office Park
• Sunscreens and solar reflector panels are exoskeletal prevent sun glare
• Electrified fence is powered by solar panels
• Solar water geysers heat up water in the bathrooms
Funding Energy Saving Initiatives
FNB will fund retrofits under their current “Cashflow payback” product
Loan will not increase current costs.
Retrofit will pay for itself between 2 – 3 years.
Increase in tariffs will increase savings
