The purpose of this Facility Ventilation Scorecard (FVS) is to allow individuals to quickly assess their facility ventilation performance levels and determine if they need to establish a Ventilation Quality Improvement program. It is based on questions that when answered will provide documented evidence of the facility ventilation challenges. The scorecard is organized into the following survey question categories and guidance:
For Visitors and Homeowners:
For Facility Staff:
ACH Level Measurement Guidance
Any score below 95 will benefit from a Quality Improvement program at: QIDC.
This data is not stored and relies on reports to be forwarded to appropriate authorities. Once these reports are accepted then the next step before a full commitment to a Ventilation Quality Improvement Indicator can be information captured in an Occupant Observations database. Jump to Occupant Observations (OCP).
Visit FVSE to see if your facility is on our database.
Change the default values in the following form and when complete, save and print the form.
When you visit a room look for a thermostat or unit ventilator and turn on the Fan if there is a fan switch available and it is not physically locked. When there is a room thermostat, move the Fan switch from Auto to On. This will turn on the fan and it will stay on regardless of temperature.

Note: Total ACH = ACH + eACH and enter only one survey value (e.g. 12+ ACH is 100, all others are 0)

The following steps can be used by staff to determine the ACH levels in each room. This can be used to determine the ACH level as part of self-certification or to check on the results provided by a vendor.
Equipment List
There is no special equipment or high cost equipment needed to execute this protocol. The equipment list is as follows:
1. Tape Measure to measure room size and vent opening sizes.
2. Handheld low cost Anemometer to measure vent air flow in Feet Per Minute (FPM).

Data Collection
1. Determine the Room ACH Level using the following steps.

2. Measure the room Length, Width, and Height in feet and calculate the room cu-ft.
Room cu-ft = Length * Width * Height
3. If there are square and or rectangular vents measure each vent opening Length and Width in inches and calculate the area in sq-in for each vent.
|
|
Vent Area = Vent Length * Width
4. If there are vents with round necks determine each vent diameter opening in inches and calculate the area in sq-in for each vent.
|
|
|
8, 10, 12, 14 Diameter |
8, 10, 12, 14 Diameter |
1-slot, 2 ft = 6 Diameter |
Vent Area = (22/7) * (diameter/2) * (diameter/2)
5. If there is an in-room unit ventilator measure the vent opening in inches and calculate the area in sq-in for each in-room unit ventilator or enter the CFM.
|
Come in 750, 1000, 1250, 1500 CFM |
Vent Area = Vent Length * Width or enter CFM if known
6. If there is an Inverter 360 Cassette measure the vent opening in inches and calculate the area in sq-in for each Inverter 360 Cassette or enter the CFM.
|
Air flow rate is selectable |
Vent Area = (22/7) * (diameter/2) * (diameter/2) or enter CFM if known
7. Measure each vent air flow using a handheld low cost anemometer.
a. Set the meter to read the maximum FPM
b. Move meter across the vent opening
c. Take multiple readings, especially for square diffuser vents
d. Use the highest most common reading
e. The numbers will be close enough
f. Use a broom stick(s) to attach the anemometer and reach ceiling vents
g. Do not use a ladder, it will significantly slow the progress
8. Calculate the total ACH using the following steps.
a. Room CFM = Total Vent sq-in * Total FPM / 144
b. Room ACH = Room CFM * 60 / Room cu-ft
