| METHODS TO SIZE ERVs |
|
| ||||
METHOD 1 |
|
|
|
| METHOD 2 |
|
| |
1. Calculate cu ft of occupied space. |
|
|
| 1. Multiply number of people times 15 CFM/person. | ||||
2. Multiply by recommended air changes per hr (AC/h). |
| 2. Multiply number of bath rooms 20 CFM/each. | ||||||
3. Divide by 60 minutes per hr to convert to CFM. |
| 3. Add 25 CFM for kitchen. | ||||||
Example: |
|
|
|
| Example: |
|
| |
2000 sq ft with 8 ft ceiling, 0.35 air changes per hr (AC/h) |
| 2 people, 2 baths, 1 kitchen | ||||||
(2000 sq ft x 8 ft ceiling x 0.35 AC/h) / 60 min/h = 93.3 CFM | (2 x 15) + (2 x 20) + 25 = 95 CFM | |||||||
