Fresh air. Naturally.
Ventive designs and manufactures Windhive® – intelligent natural ventilation with heat recovery for schools, sports halls and community buildings. Windhive harnesses wind and buoyancy to move fresh air through the building while recovering heat from the outgoing air, helping reduce energy use and maintain comfortable indoor conditions throughout the year.
Fresh air without the heat loss
Windhive combines passive ventilation and cooling with heat recovery and onboard intelligence in a single roof-mounted unit. No fans, no central plant.
Heat recovery without fans
Windhive is the only passive ventilation system that recovers heat with no fans. Passive systems without heat recovery throw warmth away; systems that recover it run fans to do so.
Silent in use
No fans at all, which supports acoustic strategies in classrooms, halls and exam rooms.
No central plant
Roof-mounted and room-served. Nothing to find space for in a plant room.
Low running cost
The only meaningful electrical load is the dampers, sensors and controls. Each Windhive uses only 2.2kWh per year, helping to keep running costs low.
Low maintenance burden
Few moving parts and cloud monitoring on every installed unit, which suits buildings with no facilities team on site.
Monitored after handover
Every unit reports internal temperature and CO2 to the Ventive cloud, to ensure optimal performance to meet relevant building regulation.
One system, multiple applications
Buildings are rarely designed the same way across different sectors. Compliance, funding and client sign-off all differ. Pick the one you are designing for.
Schools & academy trusts
BB101 air quality, exam-season overheating and whole-life cost — across SEN provision, independent schools and multi-academy trust estates.
Sports Halls & Leisure Centres
High occupancy, rising CO2, noise during play, and a running cost the club committee has to carry every year.
Community Buildings
Grant-funded projects, no facilities team on site, and a trustee board that needs the case in plain English.
