How does FanTestic calculate the pressures and flows that appear in the FanTestic UI and in the generated Word reports?
The table in the report (and the onscreen data entry fields) containing data for each Set shows:
- the “Induced pressure” and this is the pressure measured by the gauge (read automatically or entered by user) without correction for bias pressure.
- the “Fan Pressure” for each Fan, and this is the pressure measured by the gauge. (read automatically or entered by user)
- the “Flow” for each Fan, which is calculated using the Fan Pressure
- the “Total Flow” which is all the Flows added up, for all the Fans used, at that target point (will be the same as Flow if only one fan is used)
- the “Corrected Flow” which is the Total Flow adjusted as required in the chosen Standard to account for air density
(air density corrections generally

I have a Energy or Enclosure Integrity Test to perform. How many fans do I need to properly run the test? Do I have enough fans to run the test?
We have created two tools to help you figure out how many fans you will need for your test.
Download either the Blower Door or Enclosure Integrity version of the Number of Fans Calculator.
Next, open the file in excel and "Enable Editing" when a security warning appears.
Fill in all the fields highlighted in blue. The number of fan results are highlighted in green.
Here is what the Blower Door Number of Fans Calculator looks like:
And this is what the Enclosure

In California the California Energy Commission [CEC] aka Energy Standards, provide two basic methods for complying with low-rise residential energy budgets: the prescriptive approach and the performance approach. The mandatory measures must be installed with either of these approaches, but mandatory measures may be superseded by more stringent measures under either approach.
The prescriptive approach, composed of a climate zone dependent prescriptive package is less flexible but simpler than the performance approach. Each energy component of the proposed building must meet a prescribed minimum efficiency.
The performance approach is more complicated but offers considerable design flexibility. The performance approach requires an approved computer software program that models a proposed
