QUESTION 1
How Woolworths Uses Energy Responsibly & Efficiently
1. Green Building / Green Store Design
Woolworths has its own Green-Store rating model. Stores are rated Silver, Gold, or Platinum
depending on how many sustainable design features they incorporate. These include
automatic doors to manage temperature, LED lighting that adjusts with natural light, natural
ventilation, roof vents admitting daylight, under-floor heating using waste heat from
refrigeration, closed-door refrigeration and CO₂ or natural gas-based refrigeration systems.
The Palmyra Junction store in Cape Town is a flagship example, verified as a 5-star Green
Building by the Green Building Council of South Africa.
2. Real-Time Monitoring of Electricity Use
Woolworths monitors electricity usage for most of its stores, distribution centres, and head
offices using online real-time monitoring systems. These systems allow them to track usage,

2. Real-Time Monitoring of Electricity Use
Woolworths monitors electricity usage for most of its stores, distribution centres, and
head offices using online real-time monitoring systems. These systems allow them to
track usage, detect inefficiencies, and identify where energy savings can be made.
3. Refrigeration Improvements
Refrigeration is a large portion of a food retail store’s energy demand. Woolworths
has installed closed-door fridge/freezer units in its Food stores, which reduces
energy usage by about 25%. They are also adopting CO₂ / natural gas refrigeration
instead of synthetic refrigerants, which have a high global warming potential.
4. LED Lighting & Lighting Efficiency
The company is replacing older lighting (fluorescent, metal halide) with LEDs, and
using lighting that adjusts to natural light (auto-dimming or sensors). This helps
reduce energy use while maintaining good lighting for customer experience and
safety.
