Natural daylight

Natural daylight, as well as natural ventilation, are recognised factors in improving the wellbeing of a building’s occupants. Passivent’s Litevent is a controllable roof ventilation terminal combined with a rooflight that provides natural daylight.  

Controls

Passivent offers a range of controllers – intelligent and stand-alone – to suit the requirements of its natural or Hybrid Plus ventilation systems. The iC8000 is a multi-zone, intelligent controller with Passivent’s own ventilation software. It can be used as a stand-alone system, working independently, or be integrated with the building management system (BMS) using BACnet communication.

Not all situations require a fully automated system and some ventilation strategies require manual opening of louvres and windows. The eC stand-alone controllers have been designed to control individual elements of a natural ventilation system allowing the user to manually operate it. These controllers are also available with auto-close functionality after a defined period of time to remove security concerns.

Natural Daylight

The benefits of natural daylight and natural ventilation are undisputed – they improve our productivity, our focus and our wellbeing. While Passivent’s product ranges focus on natural ventilation, we also offer a product called ‘Litevent Airstract®’ in the roof terminal range that provides both – it combines a controllable ventilator with a rooflight bringing natural daylight, as well as natural ventilation into your building project.
