Revitalising Relics: Unlocking Energy Savings in Older Buildings

By Andrew King, Founder of SGT

Andrew King is the founder of SGT, a Buckinghamshire-based firm helping businesses across the UK find commercial energy tariffs that meet their needs while keeping costs low. Andrew has experience working with a range of clients and understands the needs of organisations operating in older buildings. Often, there are complexities with the building material, hardware and structure. Andrew discusses pitfalls that, if left unchecked, can drive energy costs sky high.

Older buildings are full of character, but they can also be energy guzzlers. Think of them like classic cars: beautiful, but not exactly known for their fuel efficiency. As an independent commercial energy broker and consultant, I see this all the time. Owners and facility managers are wrestling with energy costs, trying to drag these historic structures into the 21st century. It’s a challenge, but it’s absolutely doable.

Since starting in the industry, I’ve seen it all. I’ve seen facility managers tearing their hair out over energy costs that are through the roof. I’ve seen organisations struggling to balance historical preservation with modern efficiency. And I’ve seen the power of strategic energy management to transform these energy guzzlers into lean, mean, money-saving machines. For a larger portfolio, getting this right isn’t just a good idea; it’s a necessity.

Modern buildings are designed with energy efficiency in mind. Insulation, LED lighting, smart controls, renewables: it’s all built in. Older buildings? Not so much. They’re often stuck with outdated systems and construction methods that leak energy like a sieve. But don’t worry, there’s hope. Whether you’re looking at minor tweaks or major renovations, there are strategies to slash those energy bills.

Hardware: The First Line of Defence (and Windows That Don’t Leak!)

Let’s start with the basics: hardware. Doors and windows. In older buildings, especially those with historical designations, you’ll often find single-pane glass. Think of it as throwing your hard-earned cash straight out the window. Switching to double or triple glazing is a game-changer. But before you start tearing things apart, remember to check for planning permission. You don’t want to get tangled up in red tape, especially when dealing with unique campus properties.

If new windows aren’t an option, don’t throw in the towel. Window screens, thick curtains, and blinds can make a world of difference. They act like a cosy blanket, keeping the heat in during the winter and the cool in during the summer. For doors, draft excluders and brush strips are your best friends. They’re cheap, easy to install, and they seal those pesky air leaks that can drive up your energy bills. Think of the increased comfort for everyone using your facilities.

Structure: The Foundation of Energy Efficiency

Next up: structure. Older buildings are often built with stone or brick, but insulation? Not so much. Dig into the building plans and see where you can make improvements. Re-plastering walls, filling gaps under floorboards, insulating attics: these might seem like small things, but they add up to big energy savings.

Room size matters, too. Big, open spaces are expensive to heat. Consider breaking up larger rooms with interior walls to create smaller, more manageable zones for your heating system. This is particularly relevant for multi-use campus locations where different areas may have different heating needs.

Remember, though, these old buildings weren’t designed to be messed with. They were often built for residential use, not commercial, so there might be structural limitations. Proceed with caution and consult with experts. The right experts are imperative to prevent lasting structural damage and ensure the longevity of your campus estate properties.

Energy: Understanding the Beast and Taming It

Now, let’s talk about energy systems. What are you working with? Heating and ventilation? Gas? Multiple electricity meters? You’ve got to understand your current setup before you can make any changes. It’s like a doctor diagnosing a patient: you need to know what’s wrong before you can prescribe a cure.

One common problem I see is multiple electricity meters. It’s a billing nightmare. Different contracts, and different billing dates: it’s a recipe for administrative chaos and wasted money. Consolidating those meters onto a single bill can save you a fortune, not just in energy costs but in time and hassle too. I’ve seen businesses save tens of thousands of pounds a year just by doing this. Imagine the savings you could achieve across an entire portfolio.

Voltage optimisation is another smart move. Most appliances operate at around 220 volts, but you’re probably getting 240-260 volts. Voltage optimisation systems regulate that flow, saving you 15-20% on your energy bill and reducing your carbon footprint. It’s a win-win for both your wallet and the environment.

And what about solar? If your building is suitable, solar panels can be a fantastic investment. Just remember to get a battery so you can store that excess energy and even sell it back to the grid. Batteries do need replacing every few years, and solar isn’t right for every building, but it’s definitely worth exploring, especially with the long-term occupancy of campus properties.

Real-World Results: Proof Is in the Pudding (and the Savings!)

Don’t just take my word for it. I recently worked with the Tudor Hotels Collection, a group with several listed properties, including the Grade II listed Bodmin Jail Hotel and the Redcliffe Hotel. They were facing the classic problem of multiple meters and confusing billing. We consolidated their energy tariffs, and they’re now looking at annual savings of around £100,000. That’s not pocket change.

The Bottom Line: Don’t Be Intimidated, Be Smart

Bringing older buildings up to modern energy standards can seem overwhelming. But it doesn’t have to be. Start by understanding your current situation. Then, break down the project into smaller, manageable steps. Every little bit helps, and those savings can really add up. Don’t let those energy bills drain your profits and diminish the value of your campus estate properties. Revitalise your relics, unlock their energy-saving potential, and create a more sustainable and cost-effective environment for everyone.
