Facility Ventilation Scorecard

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:

TOC

For Visitors and Homeowners:

  1. Occupant Observations Ventilation Scorecard
  2. Private Residence Ventilation Scorecard

For Facility Staff:

  1. Public Space Room Ventilation Observations Scorecard
  2. Public Space Room Ventilation Levels Scorecard
  3. Public Space Facility Ventilation Operations Scorecard
  4. Public Space Facility Ventilation Maintenance Scorecard
  5. Public Space Facility Ventilation Measurement Scorecard

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.

ACH Level Measurement Guidance

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).

Example Anemometer

Data Collection

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

https://www.youtube.com/watch?v=HlneLDi9r54 (video on how to calculate air changes per hour)

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
2-slot, 2 ft = 8 Diameter
2-slot, 4 ft = 8 Diameter
2-slot, 4 ft = 10 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
physical sizes of 69, 81, 93, 105 inches
or 5.75, 6.75, 7.75, 8.75 feet

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
High, Mid, Low or 874, 729, 621 CFM.

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
