LOW CARBON SOLUTIONS
reducing building carbon emissions has never been greater. By improving the energy efficiency of existing buildings, modular FCUs provide a crucial tool in reducing carbon footprints without the need for extensive rebuilding. Moreover, as EPC requirements become stricter, investors and tenants are increasingly prioritising buildings with higher energy ratings. Commercial properties that fail to meet new energy standards may face devaluation or struggle to attract tenants. By integrating modular fan coil units, property owners can enhance their assets’ long-term marketability and ensure compliance with future regulations.
Addressing key challenges
One of the biggest challenges in upgrading commercial buildings to meet new EPC standards is the complexity of retrofitting HVAC systems. Many older buildings were not designed with modern energy efficiency requirements in mind, making it difficult to implement traditional solutions without significant structural modifications. Modular fan coil units address this challenge by offering compact designs, reduced disruption, and lower maintenance requirements. Modern FCUs are designed to fit within existing ceiling spaces, making installation straightforward. Modular FCU installations can be completed quickly with minimal downtime for occupants. Meanwhile, high-efficiency components, such as EC motors and advanced filtration, reduce the need for frequent servicing, lowering long-term operational costs.
Benefits
Beyond compliance with EPC regulations, modular FCUs offer a range of other benefits.
For instance, the ability to reconfigure and repurpose units means property owners can extend the lifespan of their FCUs, reducing waste and embodied carbon. Additionally, improvements in fan coil technology have led to lower energy consumption and quieter operation. Advanced designs optimise airflow and thermal transfer, cutting down on energy use. Meanwhile, sound levels as low as N25 (independently tested at SRL Technical Services Ltd (also known as the Sound Research Laboratory) in the latest modular FCUs means low noise enhances comfort in office spaces, hotels, and mixed-use buildings
The future
The transition to more energy-efficient commercial buildings is not just a regulatory necessity - it’s an opportunity for the building services sector to drive innovation and sustainability. As the industry moves towards Net Zero targets, building services specifiers have a critical role to play in advising clients on the best solutions for improving energy performance. Modular fan coil units represent a forward- thinking approach that balances efficiency, adaptability, and ease of retrofit. By staying ahead of regulatory changes and embracing modular HVAC solutions, contractors and property owners alike can ensure they are well- prepared for the future. The findings from the British Property Federation underscore the urgency of improving energy efficiency in commercial buildings. With the vast majority of properties still falling short of EPC B, the road ahead requires strategic upgrades and innovative solutions. Here modular fan coil units stand out as a practical, scalable, and energy-efficient option for retrofitting commercial spaces.
