In data we trust… Too easily

The biggest problem with energy and carbon data isn’t that it’s missing. It’s what we think is reliable.

Most organisations genuinely believe they have their numbers under control. Spreadsheets, smart meters, and automated reports give the reassurance that everything adds up. But scratch beneath the surface, and you’ll often find gaps, inconsistencies, and figures that can’t be traced back to the source. The data looks solid, but can you rely on it and more importantly, will it pass an independent audit process? When it comes to energy data, quality will always trump quantity.

The illusion of reliability

We live in the era of data. Most of us are surrounded by more information than we can process, and we’ve come to assume that volume equals truth. But we rarely stop to ask where the data comes from, how it’s managed, or what quality checks exist behind it.

Many of the processes we still use to gather and manage data were designed long before digital systems — some even before the advent of the personal computer. Over time, we’ve layered technology on top, automated the routines, and made them faster. But we haven’t always made them better.

This is especially evident in how we handle energy and carbon information. The systems most organisations use are patchy at best, far below the standard we’d ever accept for financial data.

What finance gets right

Executives in well-run businesses expect accuracy, traceability, and confidence in their financial reporting. Every figure is tied to a source. Every record is auditable.

Imagine managing company finances using only monthly bank statements — with no insight into what those transactions comprised, no ledger, and no verification. Most of us would call that unthinkable and predict the business wouldn’t last long. Yet that’s precisely how many are still managing their energy and carbon performance.

Yet, in our experience, most organisations have plenty of data. The problem is that it’s often siloed, inconsistent, outdated or unverified. You’d never accept unverified figures when acquiring a new business. You’d check every assumption, every claim, every piece of supporting data before signing the deal. If anything didn’t add up, you’d walk away. The same scrutiny needs to be applied to our energy data.

Moving from assumption to assurance

The first step is straightforward enough: structure. Following an established framework such as ISO 50001 is a good start. It gives us a system for collecting, validating, and reporting energy and carbon data. But structure alone isn’t enough. Data quality has to be actively managed.

This means having the right systems that make the data visible, trustworthy, and insightful for planning, monitoring, and reporting purposes, as well as validating what’s already there.

Because in the end, sustainability decisions are only as good as the data behind them. Treating energy and carbon data with the same rigour as financial data isn’t bureaucracy — it’s credibility. Because the real risk isn’t having too little data, it’s trusting data that can’t be trusted.

When the grid says no: why energy capacity is becoming a business risk

Electricity demand is rising faster than supply. Networks are struggling to cope, and for many organisations, the promise of full electrification now comes with a hidden constraint: the grid itself. Most companies are investing in electric systems for heat, cooling, and mobility. But every site has a contractual limit on how much power it can draw from the network, known as its Maximum Import Capacity (MIC). Breaching that limit comes with penalties, and getting approval to increase it is becoming harder by the month.

This isn’t a distant challenge. It’s already happening. In many regions, requests for higher MIC are being delayed or rejected because grid capacity is simply unavailable. That means organisations electrifying too quickly — or without understanding their true demand profile — could face costly load restrictions, financial penalties, or even supply interruptions. Without proper planning, forecasting and management, your organisation is at risk.

What if millions of investment can't be supported by the grid?

Electrifying heat or cooling may look like a straightforward decarbonisation win. In reality, it often creates sharp peaks in electricity demand. A cold spell, for example, can send power use soaring beyond contractual limits. Without careful planning, the systems designed to reduce emissions can become a new source of operational and financial risk.

Where resilience begins

On-site generation often tops the list of decarbonisation efforts. But real resilience starts before implementation - it starts with understanding your demand and actively managing it. Knowing exactly how and when your organisation uses energy is the foundation for controlling exposure and planning upgrades responsibly.

Historical load data provides the baseline. Continuous monitoring adds visibility. Together, they reveal how demand shifts through the day and across seasons, and where the opportunities lie to spread or reduce peaks.

For operational leaders, this isn’t just about keeping the lights on. It’s about protecting day-to-day operations, financial stability and the capacity for growth. MIC penalties, unplanned downtime, or network restrictions can all cascade into cost, compliance, and credibility risks.

Clarity before capacity

Installing solar arrays or buying more hardware isn’t the solution. The first step is clarity: knowing what’s driving demand, where flexibility exists, and how to balance electrification with grid constraints.

With the right insight, organisations can plan their decarbonisation journey without creating new risks. Energy resilience becomes part of an organisation-wide strategy, not an afterthought.

Rethinking hot water safety in a net-zero context

In many organisations, compliance with Legionella regulations is a well-established routine: maintaining elevated water temperatures, flushing outlets regularly, and logging the activity. These measures are vital for safety, but they weren’t designed with energy or carbon efficiency in mind.

Domestic hot water systems are often significant energy users, yet their impact is frequently overlooked in broader sustainability strategies. Especially in large or complex buildings, maintaining consistently high temperatures across an entire network can come at a notable carbon cost.

A balance between risk and efficiency

Much of the current approach stems from a desire to avoid risk. Heating water above 60 °C offers reassurance that bacterial growth is being controlled. But this often results in systems running constantly, regardless of actual usage or need. In practice, that could mean heating and reheating water that’s never used, or flushing litres down the drain as part of routine checks.

"It raises a question worth exploring: are all the measures in place today still necessary in every context, or are some driven more by precedent than performance?"

Understanding actual demand, outlet use, and temperature trends may help reveal where adjustments are possible - without compromising safety. But doing so requires the right data and a willingness to reassess long-held assumptions.

A more integrated view

Rather than viewing compliance and carbon as competing priorities, there may be scope to align them. Tools now exist to monitor temperature patterns more closely, control systems more precisely, and target interventions where they’re most needed.

Some organisations are already starting to explore this intersection - using insight to reduce energy use while continuing to meet safety requirements. It’s not about lowering standards, but about working smarter within them.

For organisations aiming to reduce operational emissions, domestic hot water systems may offer more opportunities than previously thought. The question is no longer just how to stay compliant, but how to do so in a way that also supports broader sustainability goals.

Why energy security is now a business-critical issue

Some resources are so fundamental that without them, business comes to a standstill. Labour, capital, raw materials, and information are the obvious ones. Among those raw materials is electricity.

For decades, energy sat in the background—seen as dependable, low-risk, and almost invisible. It was treated like stationery or cleaning products: a routine cost, assumed to be unlimited and unproblematic. That mindset is shifting fast.

Because when the power cuts out, everything stops. The recent blackout at Heathrow and failures across Spain’s national grid made that reality impossible to ignore. Energy isn’t just another input—it’s the lifeblood of modern business. And when it fails, the consequences are immediate: no electricity means no business.

The hidden risk in your operations

Most business continuity plans mention electricity—but usually as a box to tick: a backup generator, maybe an untested system buried in the appendix. What’s often missing is a clear understanding of how and when you actually use electricity. Without that visibility, even minor interruptions can lead to significant disruptions.

And this isn’t just about sudden outages. Rising demand, pressure on grids, and uncertainty around renewables all contribute to a more fragile energy landscape. If electricity is a key input to your operations, as fundamental as money or people, it deserves the same strategic attention.

Energy visibility is risk resilience

You can’t control the grid, but you can control your demand. And that starts with insight. Understanding where energy is used, when it peaks, and where it’s wasted isn’t just about hitting sustainability targets—it’s about keeping your business running.

Reducing unnecessary demand strengthens resilience. It means your operations are less vulnerable to price spikes, infrastructure strain, or supply limitations. It might even mean your critical systems can run on a smaller generator if needed. If your business plans to grow, optimisation of current use means that growth is not restricted by an electrical grid connection, for example, and can be achieved with lower costs.

The businesses that do best in the face of energy volatility are those that don’t leave it to chance. They build clarity around demand, optimise what they control, and act before disruption hits.

Energy security isn’t just about supply. It’s about knowing how your business uses energy—and what happens when it’s no longer there.

The invisible embodied carbon in reaching net-zero targets

Reaching net-zero often feels like solving the wrong problem in the dark. You upgrade the obvious. You tick the boxes. But something still doesn’t add up. That “something” is usually embodied carbon—the carbon cost baked into the technologies we rely on to deliver our decarbonisation plans.

We rarely see it. But it’s there—from the steel and cement used in construction, to the materials and manufacturing processes behind solar panels and wind turbines. These tools of the energy transition carry a carbon load of their own—and it adds up fast.

The solar paradox

Take solar panels. Long-term, they help reduce operational emissions. But upfront, they demand energy-intensive mining, manufacturing, and transport—generating carbon before a single kilowatt-hour is saved. In many cases, it can take years for panels to “pay back” their carbon cost.

This doesn’t mean solar is the wrong choice. But it does mean we need to see the full picture. Real progress isn’t just about adding renewables—it’s about asking whether we’re reducing demand in the first place.

The overlooked opportunity: operational waste

The fastest way to cut emissions—and the one with the lowest carbon overhead—is improving how buildings perform right now. Most commercial assets consume more energy than they need to. That’s often due to legacy systems, poor controls, or operational drift over time. Fixing that doesn’t require carbon-intensive materials. It requires insight, prioritisation, and action.

Before you install new tech, it’s worth asking: have you addressed the avoidable waste first?

Make embodied carbon visible by reducing what you don’t need

Embodied carbon isn’t going away. It’s part of the system. But when you reduce the need for new interventions—by improving operational efficiency—you avoid generating it in the first place. That’s where the real leverage sits. Fewer upgrades. Smaller footprints. Faster impact.

Sustainability performance needs to be tracked and managed like any other business metric. With rising carbon costs and stricter reporting rules, this will soon be non-negotiable. But the upside is clear: more efficient buildings, lower emissions, better indoor conditions—and a faster path to credible net-zero outcomes.

The power of perspective: how understanding Energy Use Intensity can transform your building’s performance

You wouldn’t drive a car without watching the rev counter. Not because it tells you how far you’ve gone, but because it shows how hard the engine’s working. Energy Use Intensity (EUI) works the same way for buildings.

Energy Use Intensity shows how much energy a building uses per square metre. The lower the number, the more efficiently the space is performing. It’s a straightforward benchmark—but it’s more than a metric. It gives decision-makers a way to step back, see what’s really going on, and move forward with clarity.

A baseline that makes action easier

When you start with Energy Use Intensity, you’re not guessing. You’re measuring. That matters—especially if you're responsible for net-zero delivery or portfolio-level decarbonisation. Energy Use Intensity gives you a normalised way to compare performance across buildings, identify outliers, and set clear, credible targets.

It’s often the first piece of insight we use with clients. Why? Because it gives immediate perspective. You can see how your performance stacks up against similar buildings, what’s driving excess use, and what needs to change first. Without sensors. Without delay. Just a starting point that makes the next step obvious.

From benchmark to outcome

Once you’ve got your baseline, Energy Use Intensity becomes a guide for strategy. You can set a target Energy Use Intensity as part of your decarbonisation roadmap. Then track how each intervention, like a system upgrade or control change, affects the result. If the number doesn’t move, you’ll know it’s time to adjust. That’s how you avoid wasted investment and stay aligned with your goals.

The benefits go beyond emissions. A strong Energy Use Intensity signals operational efficiency, and that matters to tenants and investors. In a market increasingly driven by sustainability performance, buildings with low Energy Use Intensity are more attractive, more resilient, and more future-proof.

Don’t overcomplicate it

You don’t need full real-time data capture to get started. Most buildings already provide enough information to estimate a useful Energy Use Intensity. From there, you can decide what’s worth monitoring more closely—and what can wait.

With the right insight, you can make smarter energy decisions faster. Most organisations can make meaningful improvements within six months, long before any complex tech is in place.
