Spiralling energy costs for both domestic and commercial customers is an increasing concern. A ventilation system will use energy, but there are ways to enjoy the health benefits of good air quality while keeping a lid on costs.
Energy recovery ventilation systems transfer the humidity and temperature from exhausted conditioned air to incoming fresh air. This helps to conserve energy while at the same time allowing for an increased fresh air intake.
Demand control ventilation uses CO2 sensors to calculate optimal airflow in real-time, and then make necessary adjustments to the ventilation. For instance, a room hosting a gathering of thirty people will need more ventilation than one with just one person. The system will take account of this and then send more air to the first room.
Variable speed compressors allow for hundreds of different speed settings. These can then be combined with variable blowers to enable airflow and temperature control to a precise degree while using much less energy.
