New Active Ventilation Solution From Passivent


Ventilation specialists Passivent have just launched a unique new approach to achieving good air quality with minimal energy consumption and exceptional acoustic attenuation.

The Passivent Active Range is a fully automatic system combining natural ventilation, mechanical assistance, unique SoundScoop acoustic technology and intelligent control. It gives effective and energy efficient ventilation throughout the year and in all weather conditions.

Meeting Building Regulations and Priority Schools Output Specification for ventilation and acoustics, Active Range applications include Education, Commercial and Office environments. Consisting of the Active Atrium Transfer and the Active Roof Terminal, the two products allow an ‘Active’ strategy to be deployed in most types of building, whether a single large space or a building with an atrium. Both products utilise natural ventilation for the majority of the year with a low energy boost fan for ‘Active’ operation.

The Active Range allows for three operating modes:
• Natural Mode for the majority of the year – consuming minimal energy
• Boost Mode for peak summer temperatures – reducing the need for mechanical cooling
• Recirculation Mode for the winter – mixing the air to minimise the risk of cold draughts, whilst recovering heat and reducing the burden on the heating system

Passivent offer a design strategy solution, including project consultation, in-house design and thermal modelling to develop the most appropriate ventilation strategy for each project.

Beverly Hobbs, Passivent Product Manager says:

“The Active Range offers the best attributes of a natural ventilation strategy with assistance from mechanical ventilation when required, to allow for optimum energy efficiency as external temperatures vary through the seasons, an ‘Active’ strategy”.

Passivent 2The optimised acoustic design of the Active Atrium Transfer, with SoundScoop technology means the requirements of BB93 (Acoustic Design of Schools) can be met for the transfer of air between noisy and noise sensitive spaces, for example, a classroom adjacent to a noisy atrium. The extremely low airflow resistance allows the system to be designed as a full natural ventilation system with a low energy fan to boost airflow.

The innovative Roof Terminal in recirculation mode, mixes incoming fresh air with the warm exhaust air, recovering energy, removing the heat input required to pre-warm incoming air reducing the risk of cold draughts and meeting the requirements of the Priority Schools Building Programme – Facilities Output Specification.

The Active Range control software enables monitoring of CO2 and/or temperature to ensure that good air quality is maintained, via Passivent’s Control System and can be integrated into a building management system. Building users can concentrate on their activities without worrying about ventilation/temperature.

Passivent’s Active Range can help reduce energy consumption as part of the continuing drive for zero carbon buildings, without compromising acoustic performance targets or indoor air quality as described in British Standards and Building Bulletins.
