The most energy efficient ventilation, comfort heating and cooling system in the UK.
The most energy efficient ventilation, comfort heating and cooling system in the UK.
Ventive ACTIVE combines two wall ventilators that are façade-integrated providing pure natural ventilation for schools and commercial buildings – designed to deliver fresh air at comfortable temperatures for all seasons.
100% fresh air
ACTIVE is a natural ventilation system, meaning it only supplies fresh air into rooms. It does not mix in stale contaminated air like other systems.
Enhanced heat recovery
ACTIVE combines Passive Ventilation with Heat Recovery (PVHR™) with a heat pump to be the most efficient way of delivering ventilation and comfort heating.
Connected
Once installed, ACTIVE connects automatically to the Ventive cloud to enable remote commissioning, real-time performance monitoring and proactive maintenance. Available as standard, connection is made via a GSM network to ensure security, simplicity and savings.
Silent operation
ACTIVE has no noisy fans or motors, giving occupants the silence and fresh air required for full concentration. Testing has shown it reduces external noise by an average of 45% (link)
Year-round comfort
ACTIVE adapts to the external environment automatically, delivering optimal comfort. Passive cooling and night-time purge modes minimise risk of summer overheating, while heat recovery mode in winter saves on energy bills.
Seamless design
We design, specify and manufacture each ACTIVE unit to be perfect for your specific project. We can update performance parameters to suit changing requirements.
How does Ventive ACTIVE work?
Passive Ventilation with Heat Recovery (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. Learn more.
ACTIVE enhances PVHR techniques with the addition of an efficient heat pump. Active is comprised of two wall ventilators connected by system intelligence. Warm, stale air naturally rises, and exits the room through a louvre high up on a wall. As it is leaving, the air passes through a Heat Exchanger that transfers the energy to the incoming fresh air via a heat pump connected to the bottom louvre. A number of sensors constantly monitor the temperature and air quality within the room, bringing the heat pump into action only when needed. The sensors communicate with the system’s actuators to adapt performance to changing conditions in real time. You can set custom parameters based on your own requirements, and later tweak them based on real life performance data. ACTIVE is capable of the following operation modes:
Enhanced heat recovery
During the heating season, the heat pump activates to temper the temperature of fresh incoming air, ensuring maximum comfort for occupants. Warm air passing through the exhaust louvre transfers thermal energy to liquid within the heat pump via convection, which is pumped down to the incoming air at the lower louvre.
Heat recovery
ACTIVE dynamically adjusts to sensor data from the classroom to provide an optimal balance of heat recovery with air quality. This can change multiple times during the day as occupancy levels vary.
Passive cooling
During warm conditions ACTIVE engages in secure night-time cooling. Capable of 4 air changes per hour, this method can reduce temperatures overnight by up to 10°c.
Active cooling
ACTIVE cools down incoming summer air to prevent overheating during occupied hours. It passes through the Heat Exchanger to transfer heat away to exhaust air, before flowing in to the classroom.
