System Design and Layout
T
he rst step is to determine what size system, or how many EnviroCools and QuietCool fans would work
most eectively in cooling each type home.
The type and size of home is the main factor that determines how much air should be moved through it
which give the necessary air exchanges per hour to provide sucient cooling.
T
he climate zone is an important factor, and the type of construction of the home is also a consideration.
Rules of thumb have been developed to arrive at satisfactory results for most conditions.
QUIETCOOL FAN SIZING RULES
1. For newly or recently constructed homes that have tight envelopes and are insulated to recent high
standards, 300 CFM (cubic feet per minute) of fan performance should be added for each 100 square
feet of living space. For example, a 2000 sq. ft. home should have approximately 6000 CFM fan
performance.
2. For homes in cool coastal climates, the CFM’s can be reduced by 20%
3. For homes in hot desert climates, the CFM’s should be increased by 25%
4. For poorly insulated homes and homes that are not well sealed, the CFM’s should be increased by
20%.
5. For homes with high or vaulted ceilings, the CFM’s should be increased by 10%
6. The model number of the QuietCool fan designates its CFM performance. For example, a QuietCool
QC-1500 has 1500 CFM performance, and a QC-4500 has 4500 CFM performance.
ENVIROCOOL SIZING RULES
1. One EnviroCool unit is generally adequate for up to 1,750 square feet of oor space. Two EnviroCools
are needed for homes up to 3,500 sq. ft., and add one additional EnviroCool for each additional 1,750
sq. ft. thereafter.
2. This general rule is based upon the premise that the rooms in the home that are in the pathway of
the moving air from the EnviroCool to each QuietCool fan will be cooled eectively. Those rooms not
in the pathway may not achieve satisfactory comfort levels. To overcome this problem, additional
EnviroCools can be added to these rooms if required.
LAYOUT RULES
1. Each EnviroCool must be installed in an exterior wall. It should be on the lower oor of a multi-
story
home.
2. The best layout for the EnviroCool is to place it in the room
or rooms that desire the lowest comfort
level temperatures and are as far removed as possible from the location of the fans.
The room closest
to the EnviroCool will be coolest, and the rooms farthest from it will be the warmest.
3.
Each QuietCool fan can only be installed in a room that has an attic above or adjacent to it, or has a
roof directly above it.
4. When QuietCool fans are mounted in an attic, it must be ascertained that the attic has (or is
capable
of having) vents to the outside in the amount of one square foot for each 750 CFM of fan
performance.
5. In single story houses, the fan (or fans) should be located as far as possible from the EnviroCool
location. It is recommended that each bedroom and oce have a QC-
1500 fan installed, and/or a QC-
4500 installed in a master bath. In multistory houses, the fans should be placed in upper story
rooms.
6. The fans should generally be placed near the center of each room, to allow cooling by drawing air
from the Enviro
C
ool, or from an open window when outside air is cool.
7. The ideal arrangement is to have either an EnviroC
ool or a QuietCool fan in each room or to have the
pathway of air moving from the EnviroC
ool to the fan go through each room that is to be cooled.

Each home needs to be studied and planned so that the placement of QuietCool fans and EnviroCools
will achieve the optimum performance. The following rules will be helpful.
