Natural Ventilation System

Michael Baker Boathouse - Natural Ventilation meets modern design.


Working closely with The Rooflight Company, Dyer Environmental Controls were able to contribute to the challenge of providing light with natural ventilation. Associated Architects were commissioned to design an innovative new Boathouse for the King's School Worcester Rowing Club, providing storage for the entire fleet of boats, with changing and training facilities at first floor level.

Large areas of glazing were required for the roofscape - the bespoke Plateau Rooflight provides a dramatic, continuous run of light for the length of the building and 4 pairs of casements were automated using concealed chain actuators for daily ventilation. An internal view of the rooflights reveals nothing, perfectly clean, seamless lines, the opening mechanisms completely hidden.

Each casement measuring up to 1.8m in length has three synchronised VCD chain actuators side by side opening simultaneously to 350mm for easy controlled comfort. The opening of the rooflights is controlled by individual switches with the potential of BMS control for future use. A single rain sensor is connected to all vents, any sign of rain and they automatically close.

As an example of modern design incorporating natural ventilation, the boathouse provided the opportunity for Dyer to show just how compact the VCD chain actuator really is. The ease of concealment was key to the design of these rooflights.

Smoke Ventilation Systems

This new hotel required corridor smoke ventilation, which was provided using bottom-hung outwards opening smoke windows operated by bespoke chain actuators, with each actuator delivering 500N closing force to ensure reliable window sealing when closing.  Coupled with multi-zone smoke ventilation control panels, linked directly into the building fire alarm, the hotel was provided with a discrete, unobtrusive smoke ventilation system.

Smoke & Natural Ventilation Systems

This impressive structure demanded a complex roof ventilation system which integrated both with the BMS and fire alarm.  Variable voltage signals from the BMS allowed for incremental opening of the roof vents to meet the comfort levels of natural ventilation for the occupants.  The opening of each of the roof vents was solved using a pair of fire-rated electronically synchronized rack & pinion actuators.  Upon receiving a fire signal, our control panel powered the actuators using a special high speed operation to enable opening fully within 60 seconds.  The resetting break glasses were of a flush-mounted design to keep within the building aesthetics.

Smoke & Natural Ventilation Systems

Dyer provided a bespoke, pyramidal-shaped double glazed roof vent design for this ultra-modern development to the famous cricket ground.  3 large glazed sections were linked together onto the roof to provide in excess of 10m2 of aerodynamic free area for smoke venting of the communal area.  This new design to the UK was a truly international success with Dyer working with manufacturers and suppliers from both Scandinavia and Germany.
