Things to keep in mind….. • This is for winter ONLY, no cooling (yet) • We have not (yet) set the climate • We have not (yet) set any ventilation information • We have not (yet) set the shading resolution

1) Set the Climate

1) Set the Climate: Custom ?
No functionality to import / set custom climates in DesignPH yet. If you are using custom climates from PHI, you’ll have to enter it in the PHPP AFTER you export in the later steps. For now, set your model to the closest location you can find in the list.

3) Shading Resolution
The settings here will be applied to ALL windows during analysis run. Be careful with using very high resolutions as it can lead to very long calculation times.
