Sustainability in construction is often judged by what can be seen at the end of a project, such as finished façades or the energy efficiency of windows. But increasingly, the industry is recognising that true sustainability goes far beyond the finished product.
For businesses operating across the sector, sustainability must also be embedded into the way they operate every day. From manufacturing and logistics through to fuel use and supply chain decisions, the operational side of the industry has a major role to play in reducing environmental impact. Developers, contractors and specifiers are looking more closely at the sustainability credentials of the companies they work with, while tightening regulations and future legislation continue to reshape expectations across the sector.
For Unique Window Systems, a leading fabricator of aluminium and UPVC windows, doors and curtain walling, sustainability is not simply about meeting compliance standards, but also about identifying practical, measurable improvements that can make a genuine difference across the business.
One area attracting growing attention is transport and logistics. Across the construction industry, vehicle emissions remain a significant challenge, particularly for businesses operating large delivery fleets. While the transition to fully electric vehicles remains difficult for many due to infrastructure, range and operational demands, alternative fuels are emerging as an important stepping stone towards lower carbon operations.
This has led to Unique Window Systems trialling HVO (Hydrotreated Vegetable Oil) fuel as part of its wider sustainability strategy.
HVO is a renewable fuel produced through the hydrotreatment of vegetable oils or animal fats, which significantly reduces harmful emissions. Designed as a drop-in alternative to diesel, it can be used within diesel vehicles and machinery and existing fuelling infrastructure without requiring significant vehicle modifications or operational disruption.
While the requirements for transition to this fuel source are minimal, the environmental benefits are considerable.
If fully implemented across the fleet, the use of HVO at Unique Window Systems could reduce net CO2 emissions by up to 90%. Current projections show that for every 1,000 litres of HVO used, greenhouse gas emissions could be reduced to 195kg of CO2, compared to the 3.6 tonnes generated by conventional diesel fuel.
Importantly, initiatives such as this demonstrate that sustainability improvements don’t always require extensive operational changes, and that meaningful progress can come from identifying practical solutions that can integrate into existing infrastructure.
Historically, environmental conversations within fenestration have centred heavily around thermal efficiency, glazing performance and compliance with Building Regulations. While these remain critically important, there is now growing recognition that the environmental impact of manufacturing, transport and delivery processes also forms a key part of the wider sustainability picture.
For businesses supplying major new build and commercial developments, this matters more than ever.
Across sectors such as Build-to-Rent, purpose-built student accommodation and large scale residential construction, sustainability targets are becoming increasingly ambitious. Developers and contractors are being asked to demonstrate stronger environmental performance throughout their supply chains, and as a result, those suppliers that can evidence genuine sustainability initiatives are becoming increasingly valuable project partners.
Speaking about the ongoing focus on sustainability at Unique Window Systems, and the recent HVO trial, Ashleigh Crane, Head of Compliance, commented: “Sustainability has become an important consideration across every area of construction and that includes the operational side of manufacturing and delivery. It’s not enough to simply focus on the finished product anymore. Businesses also need to look at how they operate day-to-day and where practical improvements can be made.
“For us, the HVO trial is about taking realistic and measurable steps that can reduce environmental impact without affecting the quality or reliability of the service we provide to customers. It’s a practical solution that has the potential to make a significant difference.
“We have partnered with a proven HVO supplier who can guarantee their supply chain from manufacturing abroad back to the UK for Net Zero purposes.
“What’s important now is that sustainability becomes part of the wider business mindset. Incremental improvements such as this one across manufacturing, logistics and supply chain can collectively have a major impact over time.”
Alongside emission reductions, HVO also offers operational advantages that support long-term implementation. The fuel has a 10-year lifespan, helping to reduce degradation concerns and minimise the need for regular testing. Planned investment in on-site fuelling infrastructure including a 15,000L tank, will further support operational efficiency, while helping the business maintain greater control over supply and usage.
Equally important is supply chain transparency. By working closely with suppliers able to verify the origin and sustainability credentials of the fuel throughout the supply chain, businesses can ensure that environmental claims are backed by genuine accountability and traceability.
For the construction industry, this type of operational sustainability is likely to become increasingly important in the years ahead. Far from being the focus of standalone initiatives or marketing messages, it will become an integrated part of how construction businesses and their suppliers operate, manufacture, transport and deliver.
Sustainability must extend beyond products and into every stage of the wider process. Creating more sustainable buildings now relies on building more sustainable businesses behind the scenes.
