AIRCON, AIR MOVEMENT & VENTILATION 2 ECOBUILD REVIEW
utility rooms and small offi ce applications. Some rooms just a need simple extract solution. Airfl ow’s Loovent Eco features a two-speed, dual-function fan for continuous or intermittent extraction, either of which can be selected during installation. In continuous ventilation operation, the unit will provide a constant fl ow of either 8 l/ sec, for toilets and bathrooms, or 13 l/sec, for kitchens. The unit features a low energy DC motor and a specifi c fan power of 0.3 w/l/ sec. The fan can be mounted in horizontal or vertical confi gurations to reduce the need to make good the wall once fi tted. For buildings ventilated using passive
or hybrid ventilation systems, Aereco’s G2H extract grille can provide an energy saving solution. Primarily designed for use in kitchens, bathrooms and toilets, the G2H unit fi ts directly onto individual passive ventilations ducts. It incorporates a modulating damper to control the airfl ow and is suitable for both new and refurbishment projects. There are numerous options available to enable the grille to meet the needs of applications, including: humidity control to remove moisture; presence detection; and even remote control to exhaust odours. Products to enable designers to bring
outside air quietly into a room were also on show at Ecobuild. Titon, for example, showcased a new surface-mounted noise- reducing ventilator, which is suitable for PVCu, timber and aluminium windows. The unit is compatible with standard 13 mm ventilation slots and is suitable for domestic or commercial new-build and retrofi t projects. The SF Sound Attenuator has been independently tested at a UKAS test house in accordance with BSEN2014010:1992, ISO14010:1991 and claims to provide up a sound reduction of up to 40 dB Dn,e,w in the open position and 50 dB Dn,e,w in the closed position. To make specifi cation simple, the SF
Sound Attenuator Vent and Canopy are available in a range of size combinations to suit a variety of reveals, aesthetic preferences and required levels of attenuation. Paul Duke, technical manager, Titon said: ‘With more and more developments being built on brownfi eld and urban sites, the design of ventilation systems is not just about ensuring adequate fresh air – the need to reduce potentially intrusive noise from roads or railways is now a priority.’ Monodraught has also made the
specifi cation of its Windcatcher natural ventilation system easier with the launch

Airfl ow makes heat recovery units for larger commercial ventilation applications
of the new Windcatcher Performance Component for the IESVE (Virtual Environment. IES launched the Windcatcher Performance Component Module as part of its Performance Components library within its VE software. The component allows 3D representations of the systems to be dragged easily from a product library/ catalogue onto a 3D building model and the performance and potential energy savings to be assessed. A less typical natural ventilation system
comes in the form of Dyer’s SOLIS – a solar- powered chain motor for opening windows and roofl ights using only energy from the sun. CJ
