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 sky-high energy costs, trying to drag these historic structures into the 21st century. It's a challenge, but it's absolutely doable.
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 They're often stuck with outdated systems and construction methods that leak energy like a sieve.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 Low-Hanging Fruit (and Windows!)
Let's start with the basics: hardware. We're talking doors and windows. In older buildings, especially listed ones, you often find single-pane glass. Think of it as throwing money out the window – literally. Switching to double or even triple glazing is a game-changer. But before you grab your hammer, check for planning permission – you don't want to run afoul of the local authorities, especially if the building is listed.
If new windows aren't an option, don't despair. Window screens, thick curtains, and blinds can make a real difference. They're like a cozy blanket for your windows, keeping the heat in and the cold out. For doors, draft excluders and brush strips are your best friends. They're cheap, easy to install, and they plug those air leaks.
Structure: The Bones of the Building
Next up: structure. Older buildings are often built with stone or brick, with little insulation. Dig into the building plans and see where you can improve. Re-plastering walls, filling gaps under floorboards – 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. It's like creating smaller, more manageable zones for your heating system.
Remember, though, these old buildings weren't designed to be messed with. They were often built for homes, not businesses, so there might be structural limitations. Proceed with caution and consult with experts.
Energy: Understanding the Beast
Now, let's talk 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 start making changes. It's like a doctor diagnosing a patient – you need to know what's wrong before you can prescribe a cure.
One common issue I see is multiple electricity meters. It's a billing nightmare! Different contracts, different billing dates – it's a recipe for administrative chaos. 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.
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.
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.
Real-World Results: Proof is in the Pudding
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
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 – revitalize your relics and unlock their energy-saving potential.
