From Energy Efficiency to Sustainability: The New Standard for Data Centres

For years, energy efficiency has been the gold standard for improving data centre performance. We measured success in numbers like Power Usage Effectiveness (PUE)—a way of showing how much of your power goes directly to IT equipment versus being lost to cooling, lighting, and other systems.

But here’s the truth: efficiency is only part of the story. In today’s world—where climate commitments, energy costs, and operational resilience are all front of mind—data centres need to aim higher. It’s time to move beyond efficiency to true sustainability.

Why the Shift Matters

An energy-efficient data centre still consumes vast amounts of power. If that energy comes from non-renewable sources, its carbon footprint remains high. If the design doesn’t consider manufacturing emissions or lifecycle impacts, hidden sustainability costs stack up fast.

Sustainability means looking at the whole picture:

• Energy sourcing – Is your data centre powered by renewables?

• Technology integration – Are you making the most of innovations like grid-interactive UPS systems?

• Lifecycle impacts – From the manufacturing of equipment to its end-of-life recycling, are you minimising Scope 3 emissions?

• Operational resilience – Can your systems support uptime while also supporting the wider energy grid?

  
  

How Indigi Power & Cooling Helps You Achieve It

At Indigi Power & Cooling, we specialise in designing, supplying, and maintaining mission-critical power and cooling systems that help customers achieve sustainability without compromising uptime.

Here’s how we support your journey:

1. Smart Power Infrastructure - We integrate advanced UPS technologies—like Eaton’s Energy Aware UPS—which allow you to not only protect your critical loads, but also participate in energy markets, reduce peak demand charges, and store renewable power for later use.

2. Cooling That Works With Your Sustainability Goals - Cooling is often the single biggest non-IT energy consumer in a data centre. We offer high-efficiency CRAC systems and heat management strategies that minimise energy waste without risking equipment performance.

3. Systems-Engineered Approach - Rather than mixing disconnected components, we take a whole-of-system view—ensuring every part of your power and cooling chain works together efficiently and intelligently.

4. Lifecycle Planning - From procurement to installation and ongoing maintenance, we help you make decisions that lower your carbon footprint across the entire equipment lifecycle.

   
   

The Bottom Line

Efficiency is important—but sustainability is the future. By taking a broader view, you can cut operational costs, meet environmental goals, and even create new revenue opportunities from your infrastructure.

At Indigi Power & Cooling, we’re here to help you get there—without sacrificing reliability, performance, or peace of mind.
