Save Power, Money, and CO2 with Energy-Efficient Ventilation

Whether you are renovating or building a new house, there is much to save by considering an energy-efficient ventilation solution.

Combining SKOV’s Dynamic MultiStep with SKOV LPC fans might save you up to 50% on power. Dynamic Multistep by SKOV is an innovative control principle that can be used in most ventilation systems. The control principle is specifically designed for livestock buildings, with a focus on optimizing energy usage in ventilation systems.

Fan Regulation and Grouping

Traditional ventilation systems typically operate the individual fans at full capacity, regardless of the actual ventilation needs. This approach can lead to excessive energy consumption. However, Dynamic MultiStep takes a different approach.
In this system, fans are grouped together and start at approximately 50% of their maximum performance. Two fans running 50% only use a very small fraction of what one fan at 100% does.

Adaptive Adjustment

Dynamic MultiStep is integrated with the house controller that continuously monitors the indoor climate conditions. When additional ventilation is required (e.g., due to increased animal activity or changing weather conditions), the system adapts.
Instead of turning fans to 100% one by one, Dynamic MultiStep gradually adjusts the fan speed. It activates more fans in parallel, but each fan operates at a lower output level. As a positive side effect, the gradual adjustment minimizes sudden energy spikes and reduces the noise levels significantly.

Energy Savings and Animal Comfort

The primary benefit of Dynamic MultiStep is energy savings. By using multiple fans at reduced speeds, the system achieves the desired ventilation while consuming significantly less power.

Importantly, the animals experience the same favorable climate conditions, ensuring their comfort and well-being.

Since 2012, when Dynamic Multistep was launched, SKOV has conducted many tests around the world, focusing on different climates, house types, and livestock productions. Additionally, Dynamic Multistep has also been tested by different independent research centers around the world, with great results.

A test example from SEGES Denmark (a Danish knowledge and innovation center of agriculture) tested Dynamic Multistep on a Danish farm and saw a power saving of 45% compared to regular Multistep. The power consumption went from 5.3 kWh to 2.9 kWh per produced pig. Find the full test report.

Environmental Impact

Beyond energy savings, Dynamic MultiStep contributes to a more sustainable environment. Lower energy consumption translates directly to reduced CO2 emissions.
Livestock buildings equipped with this system play a role in minimizing the environmental footprint associated with animal production.

Noise Reduction

Implementing Dynamic MultiStep not only reduces energy consumption but also leads to a quieter environment. Animals, employees, and neighbors benefit from the reduced noise level, enhancing overall well-being in and around the facility.

In summary, Dynamic MultiStep optimizes fan usage, leading to energy efficiency and less impact on the environment. Additional benefits include reduced noise levels and avoidance of energy spikes.
