Efficiency Benchmarking Methods

Is Your Process Really Efficient? Let’s Break It Down. Many teams measure productivity in terms of speed or throughput — but what really matters is value. This is where Process Cycle Efficiency (PCE) steps in. PCE = Value-Added Time ÷ Total Lead Time Let me walk you through a real-world style example, step-by-step Step 1: Define the Process Steps Let’s say we’re observing a basic production process. The steps look like this: 1. Receive material 2. Move material to the workstation 3. Wait for the operator to be free 4. Assemble the part 5. Wait for inspection 6. Perform final inspection 7. Move item to dispatch Step 2: Record Time for Each Step Step Time (min) Material movement: 10 NVA – Transport Waiting for operator: 25 NVA – Idle Assembly: 3✅ VA – Adds value Waiting for inspection: 20 NVA – Idle Inspection: 13 NVA – No value from customer’s POV Final movement to shipping: 79 NVA – Transport Total Lead Time150 Step 3: Classify Each Step as VA or NVA Value-Added (VA) Time = 3 minutes (only assembly adds value) Non-Value-Added (NVA) Time = 147 minutes (waiting, moving, inspecting) Step 4: Calculate PCE PCE= 3/150 = 2% Key Insight: If your process is running at a low PCE like this, it’s a sign that the system is busy — but not productive. Your improvement opportunity lies in: Reducing walking and waiting Eliminating rework Streamlining inspections Rebalancing workloads Automating low-value steps Benchmark: World-class operations aim for a PCE of 25% or more. Don't just work hard. Work on what adds value. #LeanThinking #ProcessImprovement #OperationalExcellence #ContinuousImprovement #PCE #WasteReduction #LeanManufacturing #TQM #ValueAdded #ProcessExcellence #EfficiencyMatters

♦What is PUE / DCiE? Power Usage Effectiveness (PUE) and its reciprocal Data Center infrastructure Efficiency (DCiE) are widely accepted benchmarking standards proposed by the Green Grid to help IT Professionals determine how energy efficient data centers are, and to monitor the impact of their efficiency efforts. ♦How to Determine PUE ? 1- Take a measurement of energy use at or near the facility’s utility meter. If the data center is in a mixed-use facility or office building, take a measurement only at the meter that is powering the data center. If it is not on a separate utility meter, estimate the amount of power being consumed by the non-data center portion of the building and remove it from the equation. 2-Measure the IT equipment loads after power conversion, switching, and conditioning is completed. According to The Green Grid, the most useful measurement point is at the output of the computer room power distribution units (PDUs). This measurement should represent the total power delivered to the server racks in the data center. ♦PUE = Total Facility Power / IT Equipment Power ♦PUE Example: Having a facility that uses 100,000 kW of total power of which 82,000 kW is used to power your IT equipment, would generate a PUE of 1.2. The 100,000 kW of total facility power divided by the 82,000 kW of IT power. ♦How to Determine DCiE ? DCIE is the reciprocal of Power Usage Efficiency (PUE). PUE is defined as the total facility power divided by the IT equipment power. That means that ♦DCiE = 1/PUE *100. ♦An example that will help you understand how to work out your data center energy efficiency: Total Facility Power = 100 kW IT Equipment Power = 82 kW DCIE = 82/100 x 100% = 82% PUE DCiE Level of Efficiency 3.0 33% Very Inefficient 2.5 40% Inefficient 2.0 50% Average 1.5 67% Efficient 1.2 83% Very Efficient ♦How to reduce PUE? ♦Cold Aisle Containment - Cold aisle containment counts as the largest contributor to the PUE improvement in combination with by-pass air flow avoidance (blanking plates, by-pass air etc.) ♦Enhanced cooling technology - Much of a data center’s energy is spent on cooling IT equipment. Whether it’s through enhanced airflow management, advanced cooling systems, or better layout, improving the cooling system can save a great deal of energy. ♦Make small improvements - Modest improvements add up. Using advanced power supplies, automatic lighting, and removing waste ensures that the whole facility contributes to a lower PUE. ♦Measure regularly - A Data center should measure its PUE regularly. Not only does this show when there is an issue, but it also provides a record of efforts and successes. ♦Why it’s important to reduce PUE? PUE and DCiE demonstrate how efficiently a data center uses energy. By understanding the amount of energy spent on different processes, companies can assess how to save money, improve service, and reduce waste. #DCDC Knowledge.

Aspects of Comparison in Energy Efficiency: What Every Professional Should Know Energy efficiency isn’t just about saving energy—it’s about understanding how and where improvements can be made. Here are four critical dimensions to guide your strategy: ✅ 1. Energy Use Index (EUI) vs Energy Cost Index (ECI) EUI: Measures physical energy units (e.g., kWh/m²/year). Great for benchmarking consumption patterns. ECI: Expresses energy use in monetary terms (e.g., USD/m²/year). Essential for financial reporting and stakeholder buy-in. ✅ 2. Energy Efficiency vs Energy Savings Efficiency: Relative metric (Output/Input) showing process effectiveness. Savings: Absolute reduction in energy (kWh or MJ). Often tied to compliance and government programs. ✅ 3. Electric Motors vs Compressed Air Systems Motors: High efficiency (90–96%) with predictable losses. CAS: Extremely low efficiency (5–15%), with 90–95% energy lost as heat. 💡 Tip: Compressed air is costly—optimize or replace where possible. ✅ 4. Operational vs Engineered Improvements Operational: Low/no-cost actions like maintenance, sensor calibration, and behavioral changes. Engineered: Capital-intensive upgrades (e.g., VFDs, heat exchangers) for long-term gains. Why This Matters Understanding these comparisons helps professionals: Prioritize low-hanging fruit before big investments. Align energy goals with cost efficiency and sustainability targets. Communicate effectively with both technical teams and financial stakeholders. As an energy efficiency expert, you have to ask yourself, what’s my go-to strategy for balancing operational tweaks and capital projects? #EnergyEfficiency #Sustainability #IndustrialEfficiency #OperationalExcellence #CostOptimization

Most energy reports end up in a folder. Nobody acts on them. So, I stopped making reports. I built an operating system instead. ───────────────────────── Introducing the Energy Efficiency Command Center ───────────────────────── One Excel workbook. 20 sheets. Multiple buildings across multiple cities. 2 years of data. Zero manual effort to refresh. Here's what it does — automatically: 🏢 PORTFOLIO OVERVIEW Total consumption, cost, CO₂, EUI, and year-on-year change across all buildings at a glance. 📊 RANKINGS + BENCHMARKING Every building ranked by Energy Use Intensity (kWh/m²/yr) against ASHRAE 90.1-2019 baselines. You see in 3 seconds which buildings need urgent action and which are performing. 📈 TREND ANALYSIS Monthly consumption curves overlaid with cooling degree days. So, when someone asks, "why did August cost more?" — the chart already answers it. 💰 COST DECONSTRUCTION Energy charge vs demand charge vs fixed charge — stacked visually every month. Because demand charges are often the silent killer in Saudi SEC bills and most teams don't even track them separately. 💡 OPPORTUNITY FINDER Rule-based engine that flags: high baseload, after-hours waste, low load factor, demand spikes, weather-normalized underperformance. Each flag comes with a SAR savings estimate (low/mid/high band). The portfolio is sitting on ~1.6M SAR/yr in identified savings. 🏅 STANDARDS COMPLIANCE — BUILT IN Not just EUI numbers. The tool calculates: → ASHRAE 90.1-2019: % improvement vs baseline, per building → ASHRAE 100-2018: Performance against existing building targets → LEED BD+C v4.1: Indicative EA points (max 20) → LEED O+M v4.1: Existing building energy performance score → EDGE v3: Energy reduction % toward certification thresholds All of this auto-populates from the same utility bill data. 🖨️ BUILDING REPORTS Select any building + year → one A4 printable page with full KPI summary, monthly trend, opportunity flags, and standards compliance snapshot. Ready for management review in 30 seconds. ───────────────────────── What this is really about: ───────────────────────── FM teams in the GCC region are sitting on enormous energy waste and in some portfolios, 20-40% above ASHRAE baselines. The problem isn't lack of data. It's the gap between data and action. This tool is that bridge: Data → Decision → Action → Evidence → Management Visibility That loop, running continuously, is what transforms an FM operation from reactive maintenance to proactive energy control. Building this kind of infrastructure is what I do. If your portfolio doesn't have a system like this yet, it should. ────────── 💬 Happy to share the methodology or discuss how something like this could work for your portfolio.
