High-volume Low-speed Fans Generate 40 Percent Savings in Energy Cost

Making open-air venues comfortable is challenging, especially during hot summers. MacroAir helps boost cooling power and lower utility costs by up to 30 percent with the MacroAir AirVolution-D high-volume low-speed fans. Using a powerful, gearless motor, this energy-efficient HVLS fan creates a constant breeze that can change the comfort level dramatically and keep large crowds in high spirits. It’s also maintenance-free and can integrate with your HVAC system, making it simple to operate.

MacroAir fans provide cost-saving comfort to the Valencia Airport. During summer months, the use of MacroAir HVLS fans has resulted in a cooling effect for passengers of between 4 and 5 degrees. This allows the Valencia Airport to increase the temperature of its HVAC system, which has resulted in significant energy cost savings.

During winter, the warm air delivered by the HVAC system tends to rise, creating a temperature difference of more than 5 degrees between the upper and lower floors of the terminal. By installing and operating MacroAir fans, the result is homogenized air and a constant temperature throughout the terminal. And this has generated a 40 percent savings in energy cost.

Test results:

• Approximate price of kWh: $0.12
• Daily savings: $0.12 x 1528.67kWh = $183.44
• Estimated Annual Savings: $183.44 x 30 x 12 = $66,038.40
• Estimated R.O.I: 1.3 months
• Projected Annual Savings: $192,697.54

Tests were performed by isolating the control of the air conditioning and ventilation system, as well as reviewing spot thermal sensation of passengers. The projected annual savings is projected by installing equipment in all three terminals.
