Sanlam

Energy management partners for the last four years.

The Challenge

Power-Star approached Sanlam in 2012 with an energy management proposal outlining a process which would allow ambitious electricity saving targets. The idea was to use money saved from behavioural change to fund capital projects to reach the set targets by 2015.

Goals:

The primary goal was to reach the sustainability target, but it was first necessary to find the low-to-no-cost interventions.

Optimization areas:

  • Tariff optimization – R1.8m pa
  • Off-peak load – optimization of the BMS settings and manual intervention where required
  • Chiller operation – changing set-points and using fewer chillers in cold weather
  • Lighting retrofit – using the savings from the behavioral change, a complete lighting retrofit is currently underway
  • Chiller retrofit – replacement of old chillers with new efficient chillers
  • Investigating the effect of replacing all desktops with laptops

The Results

2013 showed an 11.8% reduction on 2010 consumption, using only low-to-no-cost interventions. An additional 8% saving is expected for the lighting project, as well as 5% for new chillers.

Ian Erlank, Corporate Facilities Manager – “The Power-Star Energy Management programme has guided us in reaching our sustainability targets. The power of operational intervention is clearly shown in the results.”
