Automated Winter Barn Ventilation: Cut Energy Costs Without Sacrificing Air Quality

Proper air movement is vital for livestock health, but in winter, this must be balanced with maintaining warmth against cold temperatures and managing costs.

To achieve optimal airflow efficiently, automation is key to maintaining steady, stress-free ventilation. This post will detail how to automate your winter ventilation system, offering the potential to reduce energy costs while ensuring excellent air quality for your animals.

Last Seasons Settings Won’t Work

Stop letting "set-and-forget" temperature controls drive up your winter expenses. Last season's ventilation settings likely don't match your current herd or flock. Solve this with a simple routine and the right control features:

• Use controllers that help with minimum ventilation cycles, day/night timers that prevent drift.
• Don’t forget to revisit your ventilation settings often as animal counts, weight and room changes will affect your settings. 
• Add alarms & sensors so you see issues before they appear as a spike in your utility bill.
• Wireless monitoring devices like BarnTalk products enable real-time tracking of environmental conditions, providing farmers with the most accurate data for their barns. 

Moisture out, Heat in Tactic

Removing excess moisture and harmful gases from your barn is key to lowering your utility bills. Here are some strategies to ensure effective ventilation:

• Pairing fans - Clearly identify the specific fans and corresponding inlets to be used in Stage 1. The goal is to efficiently remove moisture while minimizing the use of supplemental heat.
• Confirm your true minimum - Establish your minimum ventilation rate according to the current number and weight of your animals. If you detect the odor of ammonia or observe a rise in humidity, increase this minimum setting.
• Check your systems - To ensure the incoming air follows the intended path, inspect your ventilation system for any issues like broken shutters or cracks in the inlets. If an inlet has been out of use for a season, it's particularly important to check it for any damage.

Static Pressure: The Air Jet Strategy

Keeping the right air pressure in your barn helps prevent cold drafts and saves on heating. Understanding static pressure and how to make sure it’s correct will be critical for managing temperatures in the winter. 

Static pressure is the balance between your fans and the air inlets. When it’s correct, incoming cold air shoots along the ceiling, mixing with the warm air up high before gently moving down to the animals.

However, if the pressure is too low, from faulty inlets or leaks, the cold air drops straight onto the animals, making them stressed and forcing heaters to work harder. If the pressure is too high, the inlets can’t bring in enough fresh air to remove moisture and gases.

Make sure you:

• Adjust fans and inlets to maintain the right negative pressure
• Use an automated ventilation system for consistent airflow
• Choose systems with adjustable fan speeds and inlet controls
• Make sure that cold air mixes properly with warm air before reaching animals
• Check on your animals to make sure they’re comfortable

Using Your Fans in the Winter

Investing in fans is important as they are responsible for the actual air movement, and optimizing their use is key to saving on energy costs.

• Variable Speed Fan Advantage - Variable speed fans are the most energy-efficient choice for minimum ventilation because they run continuously at partial speed to help clear moisture and gases. 
• Running Stir and Mixing Fans - Thermal stratification, when warm air piles up at the ceiling, can happen to any system, so farmers will help fight heat waste by using stir or mixing fans to help blend the warm air back down into the animal zones, reducing the risk of having cold zones in the barn. 

Automated Barn Strategies for Swine:

Maintaining pig health in the winter requires proper airflow. Base your stage-one fan speed and inlet openings on the number and weight of pigs to effectively remove moisture and gases without overworking the heaters. Ensure that the fan speed, inlet openings, and target static pressure are balanced to maintain correct air movement.

Automated Barn Strategies for Poultry:

Maintaining dry poultry litter in winter is a significant challenge for farmers. Consistent airflow is essential to remove moisture, prevent wet litter, and reduce the risk of disease. To ensure the air follows the planned path, verify that ceilings are properly sealed and inlets are functioning correctly, preventing air from leaking through wall cracks.
