Sanlam Reduces Energy Cost By 31%
Augos approached Sanlam with an innovative energy management proposal designed to achieve ambitious electricity saving targets. Their strategy involved reallocating funds saved through behavioral changes towards capital projects aimed at achieving these goals in a 3 year timeframe.
Key Objectives:The primary objective was to achieve sustainability targets, necessitating the identification and implementation of low-to-no-cost interventions.
Areas of Optimisation:
- Tariff Optimisation – Tariff savings of R3.2 million achieved in the first year through strategic tariff adjustments.
- Off-Peak Load Optimisation – Optimisation of Building Management System (BMS) settings and manual interventions to maximise off-peak efficiency.
- Chiller Operation – Adjusting chiller set-points and optimising usage during colder weather conditions to reduce energy consumption.
- Lighting Retrofit – Using savings generated from behavioral changes to fund a comprehensive lighting retrofit project.
- Chiller Retrofit – Replacing outdated chillers with new, energy-efficient models.
- Desktop to Laptop Transition – Investigating the energy-saving impact of transitioning from desktop computers to laptops throughout the organisation.
In 1 year, Sanlam had achieved an impressive 11.8% reduction in energy consumption compared to previous levels, solely through the implementation of low-to-no-cost interventions. Further savings of 8% were anticipated from the lighting retrofit project and an additional 5% from the new chiller installations.
By the close of year 2, the lighting retrofit project was successfully completed, resulting in a savings of 6.2 million kWh for the year compared to the baseline.
The momentum of savings continued, with cumulative baseline savings exceeding 31.3%.
The new target of a 10% reduction by year 8 was already surpassed, demonstrating the ongoing commitment to evaluating and implementing new energy efficiency initiatives.
