Sustainability and business growth aren’t mutually exclusive. Over the past three years, Singapore G has demonstrated this by reducing our energy consumption by 30% while simultaneously expanding our cold storage capacity by 40%. Here’s how we achieved this seemingly paradoxical result.
The journey began with a comprehensive energy audit that revealed surprising inefficiencies. Our older freezer units were consuming 45% more energy than modern equivalents, and inadequate door seals were causing significant temperature loss. We also discovered that our lighting systems alone accounted for 15% of our total energy consumption.
Our first major investment was in Variable Refrigerant Flow (VRF) systems, which adjust cooling output based on actual demand rather than running at constant capacity. This technology alone reduced our cooling energy consumption by 20%. We also installed rapid-roll doors with enhanced sealing mechanisms, minimizing temperature exchange between zones.
LED lighting with motion sensors replaced traditional fluorescent systems throughout our facilities. These lights only activate when needed and consume 60% less energy than their predecessors. In storage areas with minimal traffic, this translated to lights being off 80% of the time.
Perhaps our boldest move was installing 2,000 square meters of solar panels across our facility roofs. While the initial investment was substantial, these panels now generate 25% of our total energy needs. Combined with Singapore’s tropical climate providing consistent sunlight, the payback period is projected at just seven years.
We’ve also implemented an AI-powered energy management system that continuously optimizes our operations. It adjusts temperatures based on product types, occupancy levels, and even weather forecasts, ensuring we never use more energy than necessary.
