Main Story

So, you’re thinking about building something new? Fantastic! It’s actually the perfect moment to really nail energy efficiency right from the start. It’s not just about being eco-friendly, it’s also a smart financial move in the long run, trust me. Let’s break down how you can build something amazing that won’t cost a fortune to run.

1. Design Smart, From the Ground Up:

Before you even think about concrete, you’ve gotta think about the sun. Seriously! Where are you placing this building? You need to make the most of natural sunlight, especially during the colder months. Think about how the building will sit – a compact design is key. It reduces the surface area exposed to the elements. You don’t want to be fighting against the weather all the time, do you? And windows, oh windows! Place ’em strategically, maybe add some shading devices, you’ll be surprised how much you can reduce the need for artificial lighting and air con.

2. Insulation is Your Friend (Seriously):

Okay, this might sound boring but, insulation is where the magic happens, it’s like a cozy blanket for your building. You’ll want to invest in top-notch stuff for your walls, roofs, and floors, high performance is key. Make sure it’s all installed properly, no gaps! Air leaks and thermal bridges, they’re sneaky little things, and they’ll completely undermine your insulation efforts, and you don’t want that. If possible, consider thicker walls – they add thermal mass, which helps to regulate temperature and reduces the stress on the heating and cooling systems. I once saw a house where the insulation was so poor that it was cheaper to keep the heating on full blast instead of trying to get it to cool down. So, do it right the first time!

3. Windows and Doors – Let’s Get Serious:

Windows and doors, yeah they’re great for letting the light in, but they can also be massive sources of energy loss. Double or triple-pane windows with low-E coatings are essential, trust me. It minimises heat transfer. Choose energy-efficient frames and ensure everything is sealed up tight. You do not want any sneaky drafts. And doors, yeah the same rules apply, well-insulated and airtight. It’s all about maximising that building’s thermal performance.

4. Breathe Easy: Ventilation and Airtightness:

Airtightness is great for saving energy but you also need fresh air. So it’s a bit of a balancing act. You’ll want to install a balanced ventilation system that brings in the fresh air whilst minimising energy loss. A Heat recovery ventilation (HRV) system is a game changer. It pre-heats incoming fresh air with outgoing stale air. It’s a real smart bit of tech, that will save you money in the long run.

5. Efficient HVAC, Obviously:

When you’re thinking heating and cooling, you need to be choosing high-efficiency HVAC systems, and make sure it’s sized correctly for the building, otherwise it’ll be wasted. Geothermal heat pumps are worth thinking about. They use the earth’s stable temperature for heating and cooling and save a lot of energy. And zoned heating and cooling? A great shout, you get more individual control over the temps in different areas, more efficiency, you see?

6. Smart Tech? You Bet!:

Smart building management systems, or BMS for short, are really great for keeping tabs on energy consumption in real time. They’ll optimise lighting, HVAC, all that stuff based on how people are moving around and the weather conditions outside. Smart thermostats and lights are must-haves too! These all make automated adjustments, helping even further.

7. Light it Up (the Smart Way):

Natural light? It’s your best friend, it’s a must! Make the most of it! LED lighting fixtures, another must, they’re much more energy-efficient and use occupancy sensors and daylight harvesting to adjust lighting based on light and occupancy. Also make sure to choose lighting fixtures that have good colour rendering index (CRI) values, this will make sure everything is comfortable to look at, while minimising energy usage.

8. Water Heating Done Right:

High-efficiency water heaters, such as tankless or heat pump water heaters, are a must, also consider solar water heating systems to further reduce reliance on traditional energy sources. Low-flow fixtures and faucets? Of course! You’ll be using less water and indirectly reducing energy usage.

9. Don’t Forget Commissioning and Monitoring:

Once you have the whole thing built, you’ll want to make sure all of the systems are operating correctly, that’s where commissioning comes in. Ongoing monitoring and maintenance are very important for keeping things running well, inspect your HVAC systems regularly, lighting controls, everything, make sure it’s all working as it should.

By using all these ideas you’ll be able to create a high-performance building that minimizes energy waste. It’ll save you money and it’s also a step towards a more sustainable future. And as of January 18, 2025, these are the best practices. Also, remember that building codes and technology change, so it’s a good idea to keep up to date with the latest developments.
