Nuaire - Experts & Thought Leaders

Indoor air quality and ventilation manufacturing specialist Nuaire has announced that its Magnelis® steel-based ventilation systems are now being made from XCarb® recycled and renewably produced steel. Leading the way in sustainability, Nuaire is the first UK ventilation manufacturer to switch to this innovative steel, which will result in a 64% reduction in CO2 emissions on these products within the first year alone, compared with the same steel manufactured via the conventional steelmaking route.  Benefit from the transition to XCarb® steel Products to benefit from the transition to XCarb® steel include Nuaire’s industry-pioneering BPS air handling units and XBOXER XBC packaged heat recovery systems. For customers, this transition to a lower carbon-emission steel has only positive benefits; the quality of Nuaire’s products will remain as before, with the additional benefit of helping to reduce embodied carbon within buildings.  Less materials in building design Carbon emissions associated with the material extraction and manufacture, construction Embodied carbon - the carbon emissions associated with the material extraction and manufacture, construction, maintenance, refurbishment, and demolition of a building - makes up 20% of the UK built environment’s emissions.   To reduce this, they need to use less materials in building design, and those materials that are required should be low-carbon wherever possible. Nuaire’s ventilation systems Magnelis made with XCarb® recycled and renewably produced steel has an embodied carbon footprint of just 0.898 tCO2e/t of material, which is considerably lower than the 2.51 tCO2e/t of material of the steel previously used, meaning Nuaire’s ventilation systems manufactured with this innovative steel help reduce a building’s embodied carbon. “Mechanical, electrical and plumbing products are typically 23% of the embodied carbon of a building,” states Alun Thomas, Engineering Director of Nuaire. XCarb® low-carbon-emission steel Nuaire’s ventilation systems manufactured with this steel help reduce a building’s embodied carbon Thomas added: “This is a significant figure, so focusing on reducing it will make an important contribution to reducing a building’s overall embodied carbon. We understand customers are under pressure to reduce carbon and, like ourselves, have their own Science Based Targets they are trying to meet." "We recognize the role Nuaire has to play in helping customers meet their targets, and transitioning to XCarb® low-carbon-emission steel is one of a raft of measures we are taking to support customers and, ultimately, the planet. Being the first UK ventilation manufacturer to use XCarb® is a clear statement of our intent to drive sustainability throughout our product ranges and our manufacturing processes.” TM65 datasheets on the majority of its products As part of this support and to assist consultants and developers in measuring embodied carbon in their projects, Nuaire now provides detailed TM65 datasheets on the majority of its products to show the embodied carbon of individual products, including a breakdown of the calculation from material extraction through to end-of-life disposal. XCarb® recycled and renewably produced steel has been developed by ArcelorMittal, Europe’s largest steelmaker, as a part of their decarbonization strategy. Made in an electric arc furnace in Spain with guaranteed high scrap content and 100% renewable electricity, the steel has a third-party verified Environmental Product Declaration (EPD). New advancements in steelmaking The two companies have worked jointly for over 25-years, exploring new advances in steelmaking Nuaire was introduced to XCarb® through Steelco. The two companies have worked together for over 25-years, exploring new advancements in steelmaking with a lower environmental impact. Commenting on the relationship, Stuart Harper, Commercial Manager at Steelco, said: "Steelco is a proud partner to Nuaire and, with technical support provided by Arcelor Mittal, is excited to support their commitment to a more sustainable future, just one of many shared values between our companies. Now, as we look to the future, we have confidence that XCarb® plays a significant part in maintaining Nuaire's market-pioneering position while safeguarding the planet for future generations." Net zero by 2050 As part of the Genuit Group, which has pledged to be net zero by 2050 and has set rigorous carbon reduction targets, Nuaire has already made significant changes to its operations, which have resulted in tangible reductions to its carbon emissions. In 2024 alone, Nuaire removed 2,000 tons of carbon from its product portfolio by, for example, implementing careful material reduction and material substitution, such as changing to recycled plastic for its ducting.  2025 will see further progressive changes in Nuaire’s drive to reduce carbon, improve sustainability, and continue to provide customers with quality, reliable ventilation solutions.

Indoor air quality and ventilation manufacturing specialist - Nuaire has had its MRXBOX Hybrid Cooling Systems installed into the new Berkeley Oval Village mixed-use development in central London. 103 MRXBOX Hybrid Cooling Systems with Nuaire ducting are being installed into one-bedroom apartments at Oval Village in an area called the Zone, which are available on a shared ownership basis. Compact in size, they are being installed within each apartment’s utility cupboards. MRXBOX Hybrid Cooling System The MRXBOX Hybrid Cooling System, which is a cooling extension for the MRXBOX Mechanical Ventilation with Heat Recovery (MVHR) range, combines the heat-exchanger coolth recovery of an MVHR system with the cooling effect provided by a DX coil. A wall-mounted room temperature sensor senses indoor temperatures and activates the cooling module automatically when necessary. Addresses overheating requirements The MRXBOX Hybrid Cooling System significantly lowers the temperature of the fresh-air supply  The MRXBOX Hybrid Cooling System has been designed specifically to address the issue of overheating in problem areas of developments, where specific apartments or groups of apartments cannot be naturally ventilated, and where site-wide cooling technologies are not an option. The MRXBOX Hybrid Cooling System significantly lowers the temperature of the fresh-air supply for occupant comfort and enables compliance with Building Regulations Part O, which addresses overheating mitigation requirements in new build properties. safety considerations While passive ventilation solutions, such as opening windows, are prioritized under Approved Document O, there are instances when this is neither desirable nor practical; this could be due to safety considerations, external noise, and/or pollution. Located in the heart of London, Oval Village has these issues to contend with, plus higher temperatures than in other parts of the UK as a result of the Urban Heat Island effect. natural ventilation The MRXBOX Hybrid Cooling System was selected by the consultant on the Oval Village development following an assessment of the acoustics, air quality, and overheating. For apartments that would not meet the noise criteria, natural ventilation was not an option and an alternative solution had to be found in the form of mechanical ventilation. cost of cooling While split systems with fan coils are a tried and tested option, they weren’t universally suited Cooling technologies for individual apartments impacted by overheating were looked at. While split systems with fan coils are a tried and tested option, they weren’t universally suited to all apartments in the development. Such cooling systems come at a premium price and are relatively energy-hungry so residents have to have the means to pay to run them. With a number of the apartments at Oval Village allocated as affordable housing, the cost of cooling for the homeowner was an important consideration. indoor air quality The Nuaire MRXBOX Hybrid Cooling Systems were welcomed by the consultant as a means of achieving compliance with Part O without the energy cost of a full cooling system that occupants have to pay for. As well as creating a simple solution to overheating in summer months, the units provide a high standard of indoor air quality year-round via high-efficiency MVHR.
