ventive windhive®

natural ventilation, passive heat recovery & cooling

Ventive windhive culminates years of research, rigorous testing, performance monitoring and in-use evaluation by Ventive, the University College London and building research organisations. The new windhive range achieves significant advances in ventilation performance, combined with unique features such as passive heat recovery and passive and active summer cooling. The windhive system is easily installed through the roof using an 800mm square opening without the need for bulky upstands or additional system supports. With its striking looks and a variety of styles, colours and finishes, windhive will complement or enhance any building design.

Windhive has intelligence at the core of its operation. Each system not only monitors and reacts to the indoor environment (ensuring the right performance all year round) but also connects to the Ventive cloud as soon as it is installed - enabling remote commissioning, real time monitoring of air quality, occupant comfort and system performance, as well as ongoing adaptation, remote updates and proactive maintenance.

All of this is available as standard with no need for connection to complex building management systems or on-site network access; making windhive the most intelligent and advanced ventilation and comfort management system in the UK.

Two styles are available – smooth (rounded) and sharp (squared), with both available in any RAL colour, allowing the system to blend in or stand out as required. Both styles are available in three operational modes: passive; active and fusion; providing unprecedented design flexibility and class-leading energy performance.

Windhive can be integrated with ease into any roof type with no need for unsightly upstands or internal boxing. The technical team at Ventive will model, specify and manufacture the system to suit each project individually, so there is no need to worry about performance or appearance – simply let us know the performance criteria, colour and finish. If anything changes afterwards the performance parameters can be updated remotely.

Passive ventilation with heat recovery and comfort cooling, all in an intelligent and beautifully engineered package. Ventive windhive® is not just natural – it continuously adapts to how a building is used providing the right amount of fresh air and comfort when needed, making it the most efficient ventilation system available.
