Energy Efficiency Consulting

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

Designing and using a Building Automation System (BAS) in an existing facility to create well-balanced, efficient, and healthy buildings requires both a strategic retrofit plan and careful operational use once installed. Here’s a structured approach: 1. Assessment and Benchmarking Existing Systems Review: Gather drawings, control sequences, and recent testing/air balance (TAB) reports. Map which equipment is automated, semi-manual, or outdated. Occupant Comfort & Health Data: Collect thermal comfort complaints, indoor air quality readings (CO₂, VOCs, humidity), and hot/cold zone reports. Energy Baseline: Benchmark energy use (kWh, therms, kBTU/sq.ft) before changes to measure impact later. 2. System Design for Retrofit Open Protocols: Use BACnet/IP, Modbus, or MQTT gateways to integrate legacy HVAC, lighting, and power monitoring systems into a common BAS platform. Zoning & Control Strategies: Add VAV box controllers, airflow measuring stations, and smart dampers where feasible. Layer demand-controlled ventilation (using CO₂ sensors) to balance health with energy efficiency. Sensor Deployment: Temperature, humidity, CO₂, and occupancy sensors distributed per ASHRAE/Well Building standards. Thermal imaging or wireless sensor networks to identify air balance and comfort issues in real time. Healthy Building Features: Integrate MERV-13+ filtration monitoring and filter life sensors. Add UV-C or bipolar ionization controls (where appropriate). Tie in IAQ dashboards for occupant transparency. 3. Control Sequences & Optimization Air Balance & Comfort: Program supply/return fan tracking and static pressure reset to reduce drafts and ensure balanced airflow. Zone-level setpoint adjustment with occupant feedback loops (via apps or kiosks). Energy Efficiency: Implement chilled/hot water reset schedules. Optimize economizer use for free cooling. Integrate with lighting controls and occupancy sensors for holistic energy management. Safety & Resilience: Alarms for high CO₂, humidity excursions, filter pressure drop, or equipment failures. Cellular failover routers for visibility during network outages (cyber-secure). 4. Operational Use Analytics Layer: Add FDD (Fault Detection & Diagnostics) to identify stuck dampers, simultaneous heating/cooling, or drifting sensors. Continuous Commissioning: Periodic re-balancing aided by real-time BAS data and thermal imaging surveys. Dashboards: Tailor interfaces for facilities, executives, and occupants (different levels of detail). Training: Facility staff must be trained in both BAS operation and comfort/IAQ troubleshooting. 5. Measurable Outcomes Balanced Comfort: More consistent temperatures across spaces, reduced hot/cold complaints. Efficiency Gains: Typically 15–30% energy savings post-retrofit. Health Improvements: CO₂ maintained below 800–1000 ppm, humidity controlled within 40–60%, reduced absenteeism and improved occupant satisfaction.

Most people think consultants are paid to write clever reports. I used to think that too. And to be honest, in some cases it’s not far from the truth. When I was a CFO in the NHS, we worked with many of the well-known consulting firms. Significant sums of money were spent producing detailed reports on efficiency opportunities. The report would land. It would often confirm things we already suspected. And sometimes, if I’m being honest, the value of the report was partly about signalling upwards: “We’ve reviewed this with X consultancy and these are the efficiencies identified.” But then the real challenge started. Because identifying savings is the easy part. The hard part is three things: • turning ideas into practical actions • finding the bandwidth inside the organisation to deliver them • proving the savings actually happened That’s where many projects struggled. The recommendation might be: “If you were as efficient as system X, you could save £20m.” True perhaps. But the “how” was often much harder to translate into reality. Now I sit on the other side of the table as a consultant, and the biggest difference in the work I do is this: It doesn’t stop at the report. At ERA, the people leading projects aren’t generalist consultants. If we review waste, it’s led by a chartered waste specialist who has spent a career in that industry. If it’s fuel, water, packaging, insurance or merchant cards — it’s someone who negotiates in that market every day. Three things then happen: 1️⃣ The opportunity is identified 2️⃣ The change is implemented 3️⃣ The spend is audited quarter after quarter to make sure the savings actually stick That last part matters more than most people realise. Because costs have a habit of creeping back in. Suppliers change pricing. Usage patterns drift. Contracts quietly roll over. Without ongoing monitoring, savings can disappear surprisingly quickly. Having sat on both sides of the table, the biggest misconception about consulting is simple: Consulting isn’t about the report. It’s about what actually changes after it. And whether the savings are still there a year later. #LinkedInNewsUK

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.

ENERGY AND RETRO-COMMISSIONING This is the topic for the coming decade. It looks like we can design, model and build a pretty energy efficient building by meeting the modern code or applying one of the many low energy standards to its design. Make sure you build it right and have good inspections and testing and you should be fine. That covers new buildings. What about the existing. Clearly the number of existing buildings makes them the key to achieving everyone’s goals of energy efficiency, lower carbon emissions and energy independence. Without reduction there is no feasible way to “green” the grid and electrify fast enough to hit even the most conservative target dates. That means improve the existing stock. Whatever camp your in this just makes sense. The problem is who do you believe. The mechanical guys all have the answer, upgrade the systems and we will get you over the next hill. The window guys think it’s all about the openings, the cladding guys will fix your problems with a fiberglass clip that doesn’t “thermal-bridge” and no one wants to touch insulation in walls because that is usually like telling the king he’s got no clothes on. The truth is there is no magic bullet. They are all important and have to be done at some point, even the hard to swallow ones like insulation at exterior walls. The question is how to do it, how much do you need to do and how much will it cost. The answers will either get you in compliance or leave you with the same problem but with less fines, taxes and surcharges. We think the right approach is to pick a team that can drop the jargon, ignore the erroneous data collected by the government to put a letter on your front door and determine where you really are and where you need to go. This doesn’t start with an ASHRAE level 1 or 2 evaluation. It requires time and effort by a team headed by a real mechanical engineer that gets to know your building. They will bring in architectural specialists, facade specialists and control specialists. Together they can all create the “model” of your property. If you think some canned software package replaces these experts you will be wasting precious money and time, failing in the end. BETherm is our contribution to that effort. Small but important. Using a very advanced system of sensors we MEASURE the energy loss/gain through your buildings Envelope. Combined with component air leakage measurements we apply both to a custom weather model created for your building and produce precise energy cost estimates in terms you can understand. It’s reasonable, accurate and supported by years of government and academic research here and in Europe. Thanks to a few smart players most of our capacity for first and second quarter 2022 is booked but we just got a financing round done and will be ramping up for July, so get in touch now before the last 2 quarters are gone.

Energy efficiency (EE) is one of the most exciting, but also challenging, areas to work in. If you consider EE to be the first fuel (i.e. an energy source) its tremendously exciting because sometimes it has absolutely ZERO environmental harm, unlike any other fuel or energy source. And many people working in EE really care a lot about the environment. Coal and gas – the environmental harm is obvious. Nuclear – well there is the environmental impact and resources used in construction, radioactive waste disposal (yikes!) and end of life. Solar and wind – well there is also the environmental harm associated with mining, manufacturing and construction, and end of life disposal. Ditto for batteries (paired with wind and solar). But often EE has zero, nada, zip environmental harm. Not even 1 gram of waste or air pollution, or carbon dioxide, or methane, or disturbance of the natural environment. An example would be changing operating schedules to reduce out of hours equipment operation. The graph below shows energy usage at a small shipping port I advised. A 18% annual reduction in energy costs and GHG emissions, and air pollution from the fossil fuel plant supplying energy – but with ZERO environmental harm - just with better switch off of the massive flood lights when no ships were berthed. Essentially EE “generated” 156,480 kWh in the year immediately after the upgrade. And I might add, at ZERO cost (if you don’t take into account my consulting fee – but even if you did, the ROI was still absolutely sensational!). On the other hand, EE can be really challenging. If you are an EE advisor you need very strong technical knowledge of energy using technologies, you need to be able to sell and persuade, and you need to be good at managing risk for your client’s, and yourself. An example of such a project would be where you are advising on an air conditioning upgrade in a hospital. I’m embarrassed to say this, but looking back at my career as an EE advisor there have been times where I have provided bad advice. An example is, back in the early days of LED lighting, where the electronic drivers I had specified failed, and had to all be replaced. For me it was both embarrassing and expensive. So that you don’t make the same mistakes I made, in about a month’s time I’m looking to provide the details of a first-of-its kind energy efficiency training program which will start in mid-March, drawing on what I’ve learnt from my mistakes and successes over the hundreds of EE assessments and projects I’ve engaged in since 2001. Most people working in EE learn, painfully and slowly, on the job.The aim of the program is simple – it’s to accelerate the career of an EE advisor by five years, by helping participants learn from my experience. If you think this will benefit your career, go here to put in a preliminary expression of interest: https://lnkd.in/gFZYthtJ
