Example 1
---------

Example one aims to demonstrate that a zone achieves at least 350 lux
for 2500 hours per year or more.

\1. On the **Calculation Input** page of the wizard, change the CBDM calculation
type to **other**:

This allows you to change the *start hour*, *end hour* and *time fraction*.

\2. Change the **start hour** to **9** and the **end hour** to **17** :

This is to ensure that the number of hours in the calculation period is greater
than the target number of hours we are comparing against.

Hovering over the start/end hour text boxes will show you how many
annual hours this corresponds to.

\3. Run the CBDM calculation, and save the **tcbdm** intermediate file:

\4. Open the **tcbdm** file in the **Daylight Analysis Results Viewer** and
press **Analyse**:
