Embodied Carbon & Its Role in Decarbonisation

What is Embodied Carbon?

Embodied carbon is the total greenhouse gas emissions associated with a material, product, or construction throughout its lifecycle. Unlike operational carbon, which is emitted during a building’s use, embodied carbon is locked in from the start, making it a crucial factor in decarbonisation efforts.

It includes emissions from:

  • Raw material extraction – Mining, quarrying, and harvesting resources
  • Manufacturing and processing – Transforming raw materials into products
  • Transportation – Moving materials and equipment to the site
  • Installation & construction – Assembling products into buildings
  • Maintenance & repair – Keeping systems operational over time
  • Demolition & disposal – Managing waste and recycling materials at end-of-life

Why Embodied Carbon Matters

Embodied carbon plays a major role in reducing overall emissions in the built environment. Here’s why it’s important:

Immediate Impact

Unlike operational carbon, which accumulates over time, embodied carbon is released upfront. Reducing it from the design stage is crucial

Significant Contribution

In energy-efficient buildings, embodied carbon can exceed operational emissions.

Growing Importance

As operational emissions decrease due to energy efficiency and renewable energy, embodied carbon becomes a larger share of total emissions.

Reducing Embodied Carbon in Heating Systems

Choosing the right materials and design approach is key to cutting embodied carbon in heating systems.

Material selection

Opt for low-carbon materials that offer high performance with lower environmental impact

Efficient heat exchangers

Copper and aluminium remain the best choices due to their high efficiency, recyclability, and long lifespan

Avoid plastic-based alternatives

While some materials may appear more sustainable, plastics reduce heat transfer efficiency and increase energy demands on pumping and fans

Design optimisation

Reduce material use through smart system design.

Reuse & recycling

Incorporate materials that can be reclaimed and repurposed at end-of-life

Take Action on Embodied Carbon

Embodied carbon is a critical factor in achieving net-zero goals. By focusing on material choices, efficient designs, and sustainable practices, we can lower carbon footprints and build a more sustainable future.

Cold Weather Alert: Protect Your HVAC Coils from Freezing and Bursting

As temperatures drop across the UK, HVAC systems are at risk of serious damage. In areas where temperatures have reached as low as -10°C, frozen water inside HVAC coils can expand, causing cracks, splits, and potentially catastrophic system failures.

Why Do Coils Burst in Cold Weather?

When water inside HVAC coils freezes, it expands, creating pressure that can cause the coil to crack or split. This is a common issue during freezing weather but one that can be prevented with the right precautions.

How to Protect Your Coils from Freezing

To avoid burst coils and costly repairs, take these steps to protect your system:
1. Ensure your heating system is operational and circulating warm water to prevent freezing
2. Drain unused coils to avoid stagnant water, which is more likely to freeze
3. Check insulation and lagging for vulnerable areas that could allow cold air to reach the coils

How to Protect Your Coils from Freezing

Antifreeze or glycol solutions can be used to protect your coils from freezing. However, glycol should be considered as a last resort, as it can have a negative effect on coil performance and fluid pressure drop. Always ensure the correct percentage of antifreeze or glycol is used to maintain system efficiency.
