PHI module

This software lets you perform all the tests required by PHI certification criteria for glazings and transparent components.

When this module is active, a new interface will appear on the right side of the screen and will let you specify all the parameters required to obtain the results required by PHI.

For each element you want to test according to PHI, you must specify the Ψ value for both the thermal bridges relative to frame/glazing and installation, ie Ψinst (which, in parametric mode, is available for each node).

It's also very important to specify in which region the component will be placed; these are the other input parameters:

• g: total solar transmittance;

• β: component's inclination (90° vertical, 0° horizontal);

• θop: operative temperature;

• θa: external environment temperature.
