Step-by-Step Energy Optimisation Checklist
Addressing the energy challenges faced by UAE data centres, this checklist outlines practical steps to improve energy efficiency.
1. Assess Current Energy Efficiency
Start by evaluating your facility's energy performance. Measure total energy usage across IT systems and supporting infrastructure. A key metric here is Power Usage Effectiveness (PUE), calculated by dividing the total facility power by the power consumed by IT equipment alone. As of 2022, the average PUE stood at 1.55, meaning approximately 60% of energy in a data centre is used for IT equipment, with the rest powering infrastructure.
Additionally, track other metrics for a comprehensive picture. Water Usage Effectiveness (WUE) measures water consumption relative to IT energy use, a critical factor in the UAE due to limited water resources. Carbon Usage Effectiveness (CUE) helps assess environmental impact by comparing carbon emissions to IT energy consumption. Another essential metric is the Cooling Efficiency Ratio (CER), which evaluates the energy efficiency of your cooling systems. Since cooling can account for up to 40% of a data centre's energy use, this metric is particularly important.
Use DCIM software for real-time tracking and conduct regular energy audits to benchmark against industry standards. These insights will serve as the foundation for the next steps.
2. Optimise Cooling Systems
Cooling efficiency is a major opportunity for energy savings in UAE data centres. Start with hot aisle/cold aisle containment to prevent hot and cold air from mixing, improving cooling performance without requiring major upgrades.
Consider adiabatic cooling systems, which use evaporative cooling to pre-chill air and reduce the burden on traditional cooling units. Use CFD analysis to assess the effectiveness of your cooling strategies. For high-density setups, explore liquid immersion cooling, which is significantly more efficient than air cooling due to its superior heat transfer capabilities.
"If one thing is clear, it is that we need to be prepared for these extreme weather conditions to become more commonplace, so adapting to this inevitability is crucial."
– Karsten Winther, President for Vertiv in Europe, Middle East and Africa (EMEA)
Distribute cooling loads evenly across units to avoid overburdening specific systems. Regularly clean condenser coils - especially critical in the UAE's dusty environment - to maintain efficiency. Use pre-cooling and free-cooling during cooler months to minimise reliance on energy-intensive chillers.
3. Upgrade Hardware and Infrastructure
Modernising hardware is another effective way to cut energy use. Replacing outdated servers with newer, energy-efficient models can deliver immediate benefits. Implement server virtualisation to consolidate workloads, reducing the number of physical servers and their associated cooling demands.
For high-density workloads, liquid immersion cooling is worth considering again here. Upgrade to intelligent Power Distribution Units (PDUs), which provide real-time data and automated load balancing to optimise energy use. Simple changes, like switching to LED lighting and installing occupancy sensors in low-traffic areas, can also deliver quick energy savings.
4. Add Renewable Energy Sources
The UAE's abundant sunlight makes solar energy a compelling option for data centres. Programmes like DEWA's Shams Dubai initiative support solar panel installations, with the added benefit of selling surplus energy back to the grid. The 2024 D33 Industry-Friendly Power Policy has also removed the 1.2 MW cap on solar systems, allowing for larger installations and better returns on investment.
Calculate your Renewable Energy Factor (REF) to monitor how much of your energy comes from renewable sources. When considering solar, evaluate the total cost of ownership over 10–15 years, factoring in equipment, installation, maintenance, and potential revenue from selling excess energy.
Energy storage, such as batteries, can store surplus renewable energy for use during peak demand or low solar production periods. If on-site generation isn't an option, explore Power Purchase Agreements (PPAs) with renewable energy providers to offset your carbon footprint and support sustainability goals.
5. Set Up Continuous Optimisation
Energy optimisation is not a one-time effort. It requires ongoing monitoring and adjustments. Use the Data Centre Maturity Model (DCMM) to guide your progress and identify new improvement opportunities. Schedule monthly reviews of key metrics, quarterly deep dives, and annual comprehensive audits to ensure your strategies remain effective.
Set measurable targets, such as gradually lowering your PUE or increasing renewable energy usage. Regular tracking and fine-tuning are essential for maintaining and improving energy efficiency in the long term.
