Innovative solution for natural ventilation in schools launched by SE Controls

26 September 2012

The need to maintain precise control over carbon dioxide (CO2), temperature and energy consumption is essential to create quality learning environments in classrooms and educational buildings and SE Controls’ new compact NVLogiQ room controller provides an innovative solution to meet these demands.

NVLogiQ constantly monitors indoor air quality, temperature and humidity and uses innovative algorithms, developed in conjunction with Loughborough University’s Building Energy Research Group, to control the automatic operation of windows, vents and heating to improve learning and comfort while saving energy. A manual over-ride option is also incorporated to provide additional versatility and direct control.

Capable of being used as a stand-alone classroom controller or networked throughout schools and educational buildings, NVLogiQ’s also incorporates integrated data logging to allow detailed analysis against pre-defined design and performance criteria on both new build and school refurbishment projects.

This ability also presents a range of opportunities for consultants, contractors and facilities mangers to not only verify a school’s natural ventilation (NV) design and performance, but also to enable accurate ongoing system evaluation to be easily undertaken.

As NVLogiQ has a compact and unobtrusive, with a footprint of just 160mm x 105mm, it can be located close to desks and work areas, allowing the precise monitoring of carbon dioxide (CO2), temperature and humidity to maintain good indoor air quality and comfort levels.

SE Controls’ Natural Ventilation Division Manager, Nick Hudleston, explained: “There are clear guidelines of the volume of fresh air to be introduced into school classrooms, lecture theatres and other educational facilities to ensure that learning is not impeded by high CO2 levels as well as elevated temperatures. NVLogiQ provides a simple, compact and powerful method of monitoring these parameters and automatically controlling the natural ventilation system to maintain a productive learning environment.”

He added: “For consultants, contractors and those responsible for managing educational buildings, the data logging facility can be used for detailed ongoing analysis, allowing the NV strategy to be ‘tailored’ precisely to the needs of the students and teaching staff, while optimising energy efficiency and comfort.”

CO2 temperature and relative humidity readings are continuously displayed on NVLogiQ’s integral LCD screen while a red, amber and green ‘traffic light’ display gives a constant indication of indoor air quality. A manual over-ride capability is also built in to the room controller, allowing staff to temporarily open or close windows, louvres or other ventilation devices.

NVLogiQ’s versatile and powerful control structure has been designed to enable it to be used in a range natural ventilation strategies including cross ventilation and single sided ventilation as well as managing passive ventilation and night purging.

“From the outset, we designed NVLogiQ to provide an unrivalled mix of features, control and precision to help take indoor air quality, comfort and energy management of natural ventilation systems in education to the next level,” continued Nick Hudleston. “The innovative operating algorithms, integral data logging and the unobtrusive design, enables it to address a range of NV control and educational building management requirements in a highly versatile package.”
