AOV or Automatic Opening Vent systems control the airflow of smoke in a fire. According to EN12102-2 it is a statutory requirement to have an AOV unit on a new construction. Since 2006, Europe has required that the AOVs meet with the standards set forth in DIN EN12102-2. As a result, many companies have made their versions of AOVs. Majority of these options only go as far as barely meeting the before stated regulations. However, the Coxdome Firejet SHEV exceeds the expectations and requirements of a standard AOV.

Lampwick Quay, Manchester

Lampwick Quay, Manchester

Senior Architectural Systems Ltd

Developer Manchester Life is transforming the residential market in the city of Manchester and Senior Architectural Systems is proud to have partnered with them to create a number of apartment schemes including Cotton Field Wharf, Weavers Quay and New Little Mill. Lampwick Quay is the fourth and most recent project to have been undertaken by Senior as part of this successful repeat business relationship.Located in Manchester’s thriving new community in Ancoats, the new Lampwick Quay development comprises 213 apartments across three blocks of five, six and ten-storeys, with ground floor retail units and communal facilities including a gym and residents club room. A mix of Senior’s aluminium windows, commercial doors and curtain wall solutions have been used extensively throughout the development and installed by supply chain partner Aire Valley Architectural Aluminium for main contractor John Sisk & Son Ltd.To help reduce heat loss and energy costs, Senior’s low U value and Part L compliant PURe® aluminium casement windows have been installed to each of the apartments to create a comfortable living space. The stylish window system also provides the perfect frame for the development’s views of Manchester’s New Islington Marina.Energy-efficiency has also been addressed in the communal, retail and ground floor areas through the use of Senior’s thermally-enhanced SF52 aluminium curtain wall system which maximises the controlled use of use of natural light.To meet the scheme’s stringent safety and security requirements, Senior’s robust SPW501 aluminium commercial doors were installed to the main entrance and exit points. The SPW501 commercial door system is ideally suited to high pedestrian use and meets the requirements of Secured By Design. Key elements of the fenestration package have also been designed to work as part of the scheme’s overall passive fire protection strategy, with the use of Senior’s SPW600 automatic opening ventilation (AOV) aluminium windows in the communal areas and stairwells. Although visually similar to Senior’s popular SPW600 system, these AOV windows are fitted with a smart actuator which allows for quick and automatic ventilation in the event of a fire, helping to remove smoke from the air.The development’s low pitch sawtooth roof design pays homage the area’s industrial heritage, with the slim aluminium frames of the fenestration package further complementing the main façade of zinc cladding, brick and coloured panels. Initially designed by CallisonRTKL, the Lampwick Quay development was delivered by jmarchitects.
Mechanical smoke ventilation at Local Blackfriars

Mechanical smoke ventilation at Local Blackfriars

D+H UK

Local Blackfriars is a gated community in Salford, providing 380 apartments. A unique aspect of the residential scheme is the Grade II listed Black Friar pub merged into the development.Dyer were asked to supply and install mechanical smoke ventilation systems for the apartment blocks and the underground car parks. Dyer worked closely with Fire Design Solutions and Domis Construction over the course of the project to provide a successful outcome.When a floor goes into fire, the dampers in both shafts on the affected floor open. The chain drive on the AOV window on the affected floor opens to provide fresh inlet air. The vent at the head of the stairwell will also open. Both sets of fans work to extract the smoke and poisonous gases.On activation of a thermostat on a single floor, both the dampers on the affected floor will open. One set of fans will extract on trickle mode and the other shaft will provide fresh inlet air for the system. The vent at the head of the stair will also partly open.If the rain sensor is activated this will override and close the roof vent.If more than one thermostat operates, the dampers on the affected floors will open and be balanced to provide an equal air flow on each floor.Smoke detection in any zone will override the natural ventilation system and smoke extract will take priority.Dyer provided an eco-park® mechanical ventilation system. Advanced components and control systems allows for efficient energy usage.
