Reducing embodied carbon in building design: How underfloor air conditioning (UfAC) is a sustainable solution

As we continue to prioritise sustainability in building design and construction, the concept of embodied carbon has gained increased attention. Embodied carbon refers to the carbon emissions associated with the entire life cycle of a building, including the materials used in construction and the energy required to produce and transport those materials. One way that building designers can reduce embodied carbon is by using underfloor air conditioning (UfAC) systems.

Compared to conventional ceiling-based systems, UfAC has a lower embodied carbon footprint. It requires less associated materials, such as ductwork, pipework (Refrigerant/Water), BS boxes, cable trays and Unistrut which are energy-intensive to produce and transport. Additionally, UFAC uses less energy to operate than conventional ceiling-based systems, further reducing its carbon footprint over the lifetime of the building.

The Technique project is an example of a sustainable refurbishment that uses UfAC systems. This project is a new benchmark for the smartest re-thinking and re-invigoration of existing buildings using the highest quality materials. AET’s excellent energy credentials and the reduced volume of building materials required for an underfloor system contributed to this project’s sustainable design.

Another benefit is adaptability. As building designs and layouts change over time, UfAC can be easily modified and reconfigured to meet new requirements. This can reduce the need for extensive renovations or replacements, further reducing the building’s embodied carbon footprint.

When selecting materials and systems for building design and construction, it’s important to consider not just the immediate costs but also the long-term impact on the environment. By choosing sustainable solutions like UfAC, we can reduce the embodied carbon of our buildings and move towards a more sustainable future. With the growing concern for climate change and environmental impact, it is crucial to prioritise sustainable buildings.
