has changed the ceiling fan forever. 
USING BIG ASS FANS TO

ENERGY EFFICIENCY 
Air conditioning is not the most cost-effective method for 

controlling comfort in many environments. Short-term 

solutions such as noisy box or pedestal fans are often used 

to address comfort, but these inefficient space-eaters are 

more of a maintenance headache than a heat reliever. 

Still, increased air movement is achievable. 

CASE IN POINT: 

The Oakland Unified School District, 

(OUSD) worked to replace its old 

concrete edifice and portable 

classrooms with a healthy, efficient 

learning environment that could 

serve as a prototype for future 

projects that share a similar, mild 

climate. The goal was to comply 

with the ASHRAE Standard 55-2010 

Thermal Environmental Conditions 

for Human Occupancy comfort criteria 

without using compressorized 

cooling in high-density occupancy 

rooms. Therefore, they employed a 

three-layer strategy for maintaining 

comfort conditions, using a nighttime 

cooling cycle, thermal mass walls and 

Big Ass Fans specifically engineered 

for the space.

In this system, the Big Ass Fans are 

used to, “drop the perception of 

temperature by four to five degrees,” 

explained Brent Eubanks, mechanical 

engineer and LEED AP for Taylor 

Engineering, LLC. “If your comfort 

limit is at 78, it can be 83 degrees in 

the room and you’re still within your 

comfort threshold, thanks to the air 

movement by the ceiling fans.”

McQuay International’s Applied Air Systems replaced 100 

small box and high velocity fans in its plant with twelve 

24-ft. diameter Big Ass Fans, saving 97,656 KW and $6,347 

annually. McQuay also reduced its winter gas usage by 

32.6%, saving nearly $55,000 each year.

COOLING

AIR CONDITIONING

Why not use dozens of 

small fans?

Whenever upfront installation or energy 

costs render air conditioning economically 

impractical, Big Ass Fans are the answer. 

Big Ass Fans can replace dozens of small 

ceiling and pedestal fans at just a fraction 

of the operating cost. 

Chart 1 illustrates the cooling effect created by increased air speeds. Chart 2 references the decline in productivity if extreme temperatures are not addressed.
The two-story central gym area at Double Diamond Athletic Club in Reno, Nev., presented 

a challenge when it came to air movement. Patrons pumping iron downstairs were too 

cool, while those on the cardio balcony were feeling a little too much burn.

With a 20-ft. diameter Element® fan mixing the air, uniform temperatures keep patrons 

comfortable throughout the gym, while reducing energy bills year round.

“The Big Ass Fan has dramatically improved my club. We saved $900 a month in 

energy costs – a full return on investment within 12 months of installation.”

 AIR CONDITIONING 

In a building’s initial planning stages, including Big Ass Fans as part of the HVAC 

system allows for a significant reduction in the facility’s planned cooling capacity 

(tonnage). In addition to reducing tonnage, fans efficiently distribute conditioned air 

from ceiling to floor and wall to wall, eliminating the need for costly and unsightly 

ductwork, potentially saving tens of thousands of dollars in building materials, labor 

and design time. 

By increasing air velocity, Big Ass Fans thoroughly distribute conditioned air and 

create a cooling effect throughout the space, allowing a user to raise a thermostat set 

point. Each degree the set point is raised reduces HVAC related energy usage by 

2-3%; for example, by raising the thermostat from 74 F to 81 F, one could expect to 

save 15-20% on annual cooling. 

CASE IN POINT: 

A former retail shop found new life as DPR Construction’s net-zero Phoenix headquarters. Located in the heart of a recently 

redeveloped area and featuring a number of innovative features to improve energy efficiency, the building utilizes an ingenious 

combination of shower towers, a solar chimney, operable windows and twelve 8-ft. diameter Isis® fans from the Big Ass Fan Company 

to keep its workforce comfortable in the desert heat. The DPR Phoenix office, powered by sustainable comfort technologies, is a 

living laboratory for how to minimize the reliance on air conditioning in the desert. The space has won multiple design and green 

building awards, and received LEED® Platinum certification.

“The Big Ass Fans are a huge component to our passive cooling comfort system. It would not work without them. The fans also add 

to our look; we’ve received a lot of compliments on them.”

Andy Hill

Preconstruction manager and sustainability specialist

DPR Phoenix

Fans OR air conditioning? What a silly question! Using 

Big Ass Fans in conditioned spaces will enhance a 

mechanical system’s efficiency and capacity for cooling. 

COOLINGWITH
Big Ass Fans use their 

immense size, not speed, to 

gently and efficiently circulate 

an ocean of air throughout 

spaces, from ceiling to 

floor and wall to door. This 

thorough mixing augments 

HVAC distribution while 

reducing the need for costly 

and unsightly ductwork. 

CASE IN POINT: 

Designers of the mechanical system at 

the heart of the LEED®-Platinum office of 

Rice Fergus Miller produced a chimney 

effect by instituting a passive ventilation 

system with clerestory windows. When 

temperatures fall outside of a 15 degree 

“passive zone,” an HVAC system provides 

conditioned air. To avoid running $70,000 

worth of ductwork throughout the 

three-story alcove, the designers integrated 

variable speed heat pumps and installed 

Big Ass Fans to mix the air. The project 

was awarded a First Place ASHRAE 

Technology Award for 2013 in the existing 

commercial buildings category. After one 

year of use, the project has an EUI of 21.8 

kBtu/sf/year, 76 percent better than the 

national average for office buildings 

(93 kBtu/sf/yr).

MINIMIZING / ELIMINATING 

DUCTWORK

“The architects kept the design simple and clean by 

minimizing ductwork,” said Bud Snyder, mechanical 

engineer with Byce and Associates. “We ran a main 

trunk duct through the middle of the space and 

installed Big Ass Fans on the sides to move conditioned 

air around the entire brew house.”

Bell’s Brewery, Kalamazoo, Mich.
While other schools in the Wasilla, Alaska, school district take three or four hours to 

heat up, a 12-ft. diameter Big Ass Fan has made Machetanz’s temperature recovery 

almost immediate, increasing efficiency and lowering energy costs. Architects at 

McCool Carlson Green projected the building would perform at 8,700 mBtu/year but 

after the first full year of occupancy the building performed at 4,300 mBtu/year, 

representing over $200,000 in annual savings. 

“The fan worked as part of a system to improve the indoor 

environment of the building with a passive strategy of 

reversing the convection and getting our hot air off 

the ceiling back down to the floor,” said Jason Gamache, 

sustainability coordinator with McCool Carlson Green.

CASE IN POINT: 

Temperature gradients of 18 to 20° F 

between the floor and mezzanine 

during the heating season created 

uncomfortable and costly conditions 

at British Airways’ Hangar 6. Five 24-ft. 

diameter Big Ass Fans increased air 

circulation for a more comfortable 

and efficient workspace. British Airways 

cut energy consumption in Hangar 6 

by more than two million kilowatt hours 

and saved over $114,000 during the 

first four months of fan operation.

WINTER 

ENERGY SAVINGS / 

DESTRATIFICATION 

Because the air supplied by a heater is 

approximately 5-7% lighter than the rest of 

the air in a space, it tends to rise to the ceiling, 

creating a significant temperature difference 

between the floor and the ceiling. This natural 

phenomenon is known as stratification. A destratified 

space has only a slight temperature difference 

from floor to ceiling. Destratifying a space can 

result in heat energy savings of 30%. 

The ability of a Big Ass Fan to effectively destratify and influence all the air in a space is 

based on three primary factors – the jet of air produced, the volume of air moved and 

the lack of draft created at low speeds.

The Jet

Big Ass Fans create a slow-moving jet of air that reaches all the way to the floor. The 

airflow from small fans often struggles to reach the floor, which means it cannot 

efficiently mix the entire volume of the space, resulting in air that remains stratified. 

The Volume

The volume of air moved by the fan is critical for complete destratification; the fan must 

turn all the air in the space over at least once per hour to homogenize the air.

The Draft

Big Ass Fans are slowed – not reversed – to move a large volume of air without creating 

a draft (measured as air velocity of ~30 fpm or less at occupant level) that might cause 

an unwanted cooling effect. Reversing a fan at high speeds requires more energy and 

also increases the rate of heat loss through the roof.
IMPROVING 

VENTILATION 

AND IAQ

CASE IN POINT: 

The Big Ass Fans Research and Development Laboratory

put this concept into practice. By stationing a Big Ass Fan 

between the supply and return vents, the laboratory 

minimizes the waste of fresh, conditioned air. Because this 

air is circulated down to the breathing zone, the facility 

reduces its fresh air intake by 20%. 

LUNCH & LEARNS

Our Big Fan Experts and Applications Engineers are available to 

discuss any specific project needs or schedule a Lunch and Learn to 

earn continuing education credits for your firm.

PUTTING LEED INTO PRACTICE

The lab was designed for the unique requirements and challenges

of testing large diameter, low speed fans. The unique attributes 

of the building allow Big Ass Fans’ dedicated R&D staff to 

conduct fan performance testing including fan-generated air 

velocity profiles, fatigue testing of complete fan assemblies 

and components, as well as build full-scale prototypes of the 

newest fan designs. The lab achieved LEED-Gold certification 

through the USGBC and includes numerous green design strategies:

•	35% reduction in building energy cost when compared to an

ASHRAE Std. 90.1-2004 code minimum building.

•	Elevated air speed is used to offset an increased thermostat

setpoint (per ASHRAE Standard 55-2010).

•	The HVAC design incorporated Big Ass Fans which ultimately

lowered the static pressure experienced by the supply fan and 

increased the efficiency of the air distribution system.

•	One year after the grand opening, it was determined that the

lab consumed~18 kBtu/ft2-yr of energy—slightly less than the 

average vacant building.*

Big Ass Fans can help contribute to earning LEED credits in 

the following categories:

•	Energy and Atmosphere

•	Indoor Environmental Quality

•	Innovation in Design

* Commercial Buildings Energy Consumption Survey (CBECS)

The Big Ass Fans Research and Development Laboratory is dedicated 

to developing the world’s most energy efficient fans. 

Many buildings have both their 

supply and return vents located 

on the ceiling. This works great in 

the summer, when cold, 

conditioned air drops out of the 

vents and straight to the floor. 

But heated air? Not so much.

Big Ass Fans aid zone air distribution effectiveness by gently 

pushing the warmed air down to the breathing zone and away 

from the return vents, reducing the amount of freshly heated 

air that is wasted due to short circuiting. Facility designers 

can use Big Ass Fans to circulate conditioned air throughout 

the space and reduce their fresh air intake by up to 20% without 

a negative effect on indoor air quality.

Challenge

With doors constantly opening, consistent temperatures were difficult to maintain in the non-air conditioned and 

poorly insulated Kentucky National Guard helicopter maintenance hangar. The Guard needed to create and maintain 

a stable temperature throughout the hangar to improve both technicians’ comfort and energy efficiency.

The Kentucky National Guard installed a 24-ft. diameter Powerfoil®X2.0 and immediately felt the difference. The

Powerfoil X2.0 boasts its own patented airfoil system, which increases the fan’s overall coverage area by 28%. 

The fan improves summer comfort and winter efficiency, without added distraction or noise. 

SOLUTION

“I’m extremely happy with the fan. We keep it going year round. If we turn it off, 

even to weigh an aircraft, the shop immediately calls and wants to know why.”

 Jeremy Knight, Mechanic

Kentucky National Guard
