Rooflights & Roof Vents

A pioneering option in lighting is giving a ‘best of both worlds’ scenario, optimising natural resources whilst ensuring acceptable light levels are maintained day and night.

Sunscoop Hybrid has been developed by Passivent, supplier of internal environment solutions which minimise energy consumption.

The lighting system combines the proven and established Sunscoop tubular rooflight technology with an additional low-energy luminaire.

Sunscoop Hybrid reflects natural daylight through a roof-mounted glazed dome and highly reflective tubing to a ceiling-mounted diffuser in the room or dark area below, providing up to eight times the amount of light of a single 60W electric bulb; a 26W fluorescent lamp that can be dimmed in the diffuser unit is triggered to turn on when the integral light sensor detects lux levels drop below a predetermined level. When natural light levels rise, the lamp automatically turns off.

A further programmable PIR presence detector turns off the lamp regardless of light levels if the room is unoccupied.

Georgina Park, Passivent Commercial marketing executive, elaborated: “Tubular rooflights are great for reducing the need for artificial light, but are dependent on a reasonable level of daylight: on very overcast days, early morning or late afternoon, the light may not be adequate for the room occupants.

Sunscoop Hybrid overcomes that issue, ensuring the light level is always acceptable, whilst optimising energy usage, and giving occupants the choice to supplement natural light if required: research by CIBSE shows that giving people that choice can make up to 40% difference to the resulting light use.”

Passivent’s Sunscoop Hybrid is initially available in a 350dia unit as standard, for installation in both new build and refurbishment projects.

Sunscoop’s Skyview diffuser, which enhances the spread of light and allows the sky to be seen through the unit, can be included as an option.
