When can you enjoy the benefits of HVLS Fans?
The benefits HVLS fans provide are numerous. First of all, HVLS fans are air movement systems, not just cooling systems. They move and mix lots of air. As a result of the masses of air they move they are very effective in aiding cooling, heating (through heat de-stratification) and ventilation. They also mix bad and noxious air, including humid air, reducing damage and waste (and disease) due to unwanted moisture, and creating a healthier atmosphere to breathe. As a side benefit they help eliminate birds and bugs and all the environmental damages they cause. And with all the energy they can save you can argue they ultimately make the world a better and safer place!
As you learn more about HVLS fans, you will find the major benefits of their quiet and gentle airflow are -
- Summer Cooling - Large masses of air are moved at an optimal speed to create an evaporative cooling effect of 6 to 14 degrees or more. A cooler environment is created more effectively over large areas with HVLS fans, while replacing many other air movement solutions that typically require much greater power and energy.
- Winter Heat De-stratification - At least 20% or more (often much more) in heat savings is realized in colder seasons. The industry rule of thumb suggests that there is about a 3% - 5% savings in energy required for every degree of thermostat reduction. Heat de-stratification doesn’t result in thermostat reduction but results in less frequent heater cycling, creating the same basic effect. Most high roof facilities (usually with heaters in the ceilings trying to blow the naturally rising hot air down) have a 15 to 30 degree differential or more from floor to ceiling. HVLS fans mix the air to make a more easily maintained uniform temperature and help eliminate heat loss from infiltration through ceiling and roof materials.
- As an alternative or supplement to Air Conditioning - where air conditioning is present, HVLS fans provide comparable cooling comfort while enabling 3 to 8 degree thermostat increases with 3% to 5% energy reductions per degree. All while eliminating costly ducting and air conditioning tonnage (and related costs to install and maintain).
- Year-round Ventilation and Related IAQ - HVLS fans efficiently and more effectively mix incoming fresh air with stale air, reducing the need for more costly solutions while also minimizing the volume of air needing to be replaced (and corresponding loss of warm or cool air). And as big air mixers they are phenomenal at dispersing fumes and moisture concentrations throughout larger air volumes, reducing their undesirable effects.
Simply put, in summary, HVLS fans with their gentle and non-disruptive air movement create an evaporative cooling effect of 6 to 14 degrees or more in hot environments. In cold environments they de-stratify hot air rising to ceilings, enhancing comfort, and, more importantly, reducing heat loss and related energy costs by 20% to 80%. Similar savings are experienced as a supplement to A/C. As a bonus, their highly effective air mixing and ventilation result in drier, cleaner, fresher, and healthier air. Energy and operating costs go down while productivity goes up. Payback periods are short (often less than a year - look for more on energy and related cost savings in a future blog) and ROI very high due to significantly reduced operating costs and elimination of energy waste and loss.
