2. Specification Ventive Windhive is a roof-mounted Passive Ventilation system with Heat Recovery (PVHR™). PVHR is a patented method of delivering high thermal efficiency and consistent air flow using natural ventilation systems, by securely transferring the heat from exhaust air to fresh incoming air. The Ventive Windhive has several sensors that constantly monitor the temperature and air quality within classrooms and other school spaces. The sensors communicate with the system’s actuators to adapt performance to changing conditions in real time. The parameters set will ensure a comfortable...

naturally intelligent buildings ■ Providing ventilation at 200 litres per second using 0W ■ Heat Recovery of up to 72% using 0W ■ Night time cooling provides 4 air changes per hour reducing the indoor temperature by up to 10°C Windhive is capable of the following operation modes: Windhive passes 100% fresh air through pure natural ventilation. The PVHR method ensures there are no cold draughts, reducing heat loss by up to 72%. In winter the dampers close to produce an airlock and ensure heat is retained overnight. Windhive dynamically adjusts to sensor data from the classrooms to provide an optimal...
