Engineering sustainable outcomes

Phillip Handley, Country Manager for Walraven highlights the key material and lifecycle considerations for sustainable M&E support systems

As the building services industry intensifies its focus on net zero targets and circular economy principles, mechanical and electrical (M&E) contractors are increasingly expected to embed sustainability into every aspect of their work.

While much attention is given to major equipment and energy systems, the fixings and modular support systems that underpin these installations are often overlooked. Yet, they represent a significant opportunity to reduce embodied carbon, improve material efficiency, and enhance long-term adaptability.

Here, we explore how sustainability can be considered when selecting M&E fixings and modular support systems, offering practical guidance for specifiers, contractors, and designers.

1. Material Selection and Embodied Carbon

One of the most direct ways to reduce environmental impact is through careful material selection:

• Sustainable sourcing: Consider manufacturers who practice sustainable sourcing. This means they procure products, services, and materials in a way that minimizes negative environmental and social impacts while ensuring long-term economic viability.

• Environmental Product Declarations (EPDs): Choose fixings and supports with verified EPDs to quantify their environmental impact across the lifecycle.

• Avoid over-specification: Select components that meet performance requirements without excessive strength or bulk, which can lead to unnecessary material use.

2. Modular Design and Reusability

Modular support systems offer inherent sustainability advantages:

• Ease of disassembly: Modular systems can be dismantled and reused in future projects, reducing waste and promoting circularity.

• Adaptability: Systems designed for flexibility can accommodate changes in building use or layout without requiring complete replacement.

• Reduced site waste: Pre-engineered modular components minimise cutting and fabrication on site, lowering material waste and improving installation efficiency.#

3. Supply Chain and Manufacturing Practices

Sustainability extends beyond the product itself:

• Local sourcing: Prioritise suppliers with local manufacturing to reduce transportation emissions and support regional economies.

• Responsible sourcing certifications: Select suppliers certified with ISO 14001 or similar environmental management standards.

• Lean manufacturing: Engage with manufacturers that use energy-efficient processes and minimise scrap material.

4. Installation Efficiency and Site Impact

The sustainability of fixings and supports is also influenced by how they are installed:

• Tool-free or low-energy installation: Systems that require minimal power tools or hot works reduce energy use and improve site safety.

• Pre-assembled kits: These reduce time on site, lower labour costs, and decrease the likelihood of errors or waste.

• Lightweight components: Easier handling reduces the need for lifting equipment and improves ergonomics for installers.

5. Lifecycle Considerations and Maintenance

Sustainable selection must account for long-term performance:

• Corrosion resistance: Durable coatings and materials extend service life and reduce the need for replacements.

• Standardised components: Using widely available parts ensures future compatibility and simplifies maintenance.

• Design for deconstruction: Systems that can be easily removed without damaging surrounding infrastructure support future upgrades and reuse.

Conclusion

Sustainability in M&E fixings and modular support systems is not a niche concern—it’s a strategic imperative.

As the industry moves toward net zero, every component counts. Fixings and supports may be small in size, yet their impact is anything but.
