Email:chenzhenxiang@optfan.comHVLS Giant fans are the most energy efficient climate control solution. They use minimal energy to deliver airflow, which reduces both heating and cooling costs. HVLS Giant fans also distribute air so well they supplement and even exceed HVAC ducting. Here’s how it works:
1. Reduced Cooling Costs
According to the NASA employee productivity study, we see that airflow decreases the perceived temperature. With HLVS Giant fans creating airflow, employees feel cooler because convective and evaporative cooling is facilitated, not because the actual air temperature is any cooler. Human comfort is typically the goal of cooling indoor spaces, and we can achieve that goal in more than the one, traditional way known as turning down the thermostat! With fans aiding in climate control, you can increase your thermostat setting while staying equally comfortable. Did you know that each degree the thermostat is increased accounts for a 5% reduction in kWH usage? So if a facility increased its thermostat by 5°, they would see a 20% reduction in cooling costs! As you can see, HVLS fans quickly deliver a return on investment.
2. Reduced Heating Costs
Let’s look at reducing heating costs. Without air movement, buildings with high ceilings experience heat stratification – cooler air at floor level and warmer air at the ceiling. The temperature typically increases half a degree each foot, so the temperature difference between the floor and rafters of a 20-foot building would be about 10 degrees.
During the winter, HVLS Giant fans can run in reverse to de-stratify and re-distribute the air. This is particularly effective if you are planning an air circulation strategy that includes a forced air heating system. Pairing a heating system with HVLS Giant fans typically yields a 30% savings on heating costs by increasing warm air at ground level and reducing heat loss through the roof.
3. Decreased HVAC Tonnage & Ducting
When HVLS Giant fans are included in the building planning phase, the fans are tasked with distributing air throughout a building. As we mentioned earlier, HVLS Giant fans effectively mix air to achieve comfort levels and reduce HVAC demand. Including HVLS Giant fans in a building design can also reduce the required HVAC tonnage and eliminate the ductwork. The implication of eliminating ductwork is elimination of the space, labor, and materials formerly allocated to accommodate ducting for air handling. HVLS Giant fan technology is a great way for companies to reduce their carbon footprint by decreasing the size of their HVAC systems. Plus, it’s consistently effective to use HVLS Giant fans rather than ducting because HVLS Giant fans are in service all the time, mixing the air in the space and keeping a consistent comfort level rather than dumping hot or cold air into a space.
The cost of ducting is roughly the same as the corresponding HVLS Giant fan or fans, so it’s worth considering the advantages – not the least of which is how much more interesting the aesthetic appeal of a sleek fan is over metal ducting and vents!
Bottom Line
Installing HVLS Giant fans in your building will provide an effective year-round climate control solution. These fans consume minimal energy and deliver maximum environmental benefits.
