Nuaire ventilation systems now with Passivhaus certification


I


ndoor air quality and ventilation manufacturing specialist Nuaire is pleased to announce Passivhaus certification has been achieved on BPS Passivhaus air handling units (AHU) and XBC Passivhaus packaged heat recovery units. With buildings contributing significantly to harmful carbon emissions, Passivhaus provides proven solutions to deliver net-zero-ready buildings that also provide a high level of occupant health and wellbeing. Passivhaus adopts a whole-building approach with clear, measured targets, focused on high- quality construction, certified through an exacting quality assurance process. For a building to achieve the Passivhaus Standard in the UK, a mechanical ventilation system with highly efficient heat recovery is considered a core principle. Rigorously independently tested under realistic conditions to ensure they meet the strict Passivhaus


efficiency, thermal comfort, and indoor air quality criteria, Nuaire’s BPS Passivhaus AHUs in sizes 12,17, 22, 32 and 42, and XBC Passivhaus packaged heat recovery units in sizes 55 and 65 have now been certified as Passivhaus compliant components. BPS Passivhaus is a range of high specification packaged AHUs designed and engineered to provide


an efficient, high performing, compact solution for a multitude of applications. Efficiency comes from a dual compressor system that uses less energy than one single large compressor, a high efficiency thermal wheel, and minimal air leakage (it has the top L1 leakage classification). BPS Passivhaus AHUs feature a high quality double lined acoustic end panel insulated with Rockwool for reduced noise breakout and low leakage, ensuring the unit is airtight. BPS Passivhaus AHUs feature M5 extract air filters, enabling pollutants as small as 1 micron to be captured, and G4 and G7 supply air filters which are designed to stop larger pollutant particles from entering. With a plate heat exchanger with efficiencies of up to 95%, XBC Passivhaus are high performance


packaged heat recovery units designed to improve indoor air quality whilst saving energy. High classification F7 and G4 extract filters have been installed to ensure the units meet the high Passivhaus air quality standards, whilst airtight seals prevent heat or air loss up to L2 leakage classification. They have been designed with the lowest possible noise breakout for user acceptance, and are easy to install, commission and maintain. XBC Passivhaus is available with LPHW or electric heating options as standard, with cooling modules also available as an ancillary. Both BPS Passivhaus and XBC Passivhaus are fitted with high classification class 3 dampers to ensure the units remain airtight, mitigating weak points in a Passivhaus build.

U www.nuaire.co.uk/commercial/passivhaus


nicrimp, part of the Scolmore Group, has expanded its comprehensive Q-Fire range of fire-rated products with the introduction of new sizes of its popular stainless steel metal cable ties. This enhancement provides installers with greater flexibility and choice when working in


demanding, safety-critical environments. Stainless steel cable ties are widely used as a secure and versatile fastening solution for bundling and supporting cables, wires, and components — particularly in settings where high strength, durability, and fire resistance are essential.

Already part of the Q-Fire product offering, the stainless steel cable ties have now been made


available in additional sizes - 200mm x 4.6mm, 300mm x 4.6mm and 360mm x 4.6mm. With these additions, the Q-Fire range now includes metal cable ties in sizes from 150mm x 4.6mm up to 840mm x 7.9mm, offering greater flexibility for diverse installation requirements. All sizes comply with BS7671 IET Wiring Regulations, ensuring full regulatory alignment for professional electrical installations The expanded cable tie range complements the full suite of Q-Fire fire-rated products, which includes


all round banding, LSF coated saddle clips and p clips, fire safe metal cable clips, stainless steel mounts, and fire resistant sealants and foams. The full Q-Fire brochure is available to download on the Unicrimp website – and on the Scolmore Group app.

TRILUX Supports Flexible Learning Spaces in N Family Nursery Rollout


future-proof solutions. TRILUX impressed with its strong product portfolio and the flexibility to adapt designs for the specific demands of each site – whether conversions of historic churches, galleries, or purpose-built spaces. Peter Spencer MCIOB, from N Family Club, commented: “TRILUX offered exactly what we needed,


with a range of high-quality fittings that meet both our aesthetic design standards, and operational requirements. They have been proactive from the outset in helping find solutions to address the specific demands of each project and supporting our design and construction teams in providing expert knowledge and advice to ensure we achieve the best possible results.” Working closely with the client and contractors, TRILUX supplied all fittings onsite, ensuring a


streamlined process from specification to installation. The lighting design was centred around creating a high-end look and feel while supporting the


nurseries' flexible learning environments. Thanks to the wide range of optical systems in E-Line Pro, each area could be individually tailored, offering excellent glare control and a high colour rendering index of Ra >90 – perfect for stimulating young minds. Indoor lighting was carefully zoned to match learning activities, from focused tasks in classrooms to


playful spaces like the Atelier art rooms. Meanwhile, robust external lighting ensured outdoor learning areas remained accessible and welcoming in all seasons – a key part of the N Family Club educational philosophy. Mike Cheeseman, Plenarius Design, M&E Consultants, commented: "TRILUX's expertise in education


lighting was invaluable. Their understanding of how light influences learning environments helped us achieve exactly what the client wanted – outstanding spaces that support both child development and operational efficiency." Leatherhead was one of the key sites under this major rollout, with TRILUX solutions now forming the benchmark for all future N Family Club projects. The lighting toolbox includes:
