Export Schedules

Is it possible to export the standard implemented schedules of DesignBuilder for using them as imports to Grasshopper/Honeybee?

Re: Detailed HVAC Schedules

There are two places to set the temperature setpoints for a zone:
in the tab 'activity' and in the zone group 'thermostat schedules'.

Why is the tab activity not green highlighted?
Will the temperature settings in the tab 'activity' somewhere be used in energy simulations or other simulations?

Move imported bitmap

Is it possible to move an imported bitmap?

I can scale the bitmap and set the X-axis, but I don't know how to move a reference point?
Can I move the imported bitmap, or do I have to move the buildings?

Relative Humidity

I have some problems to control the relative humidity in an zone (40 – 60%) in design builder. Detailed HVAC is used: "7-multizone humidity maximum" & "6-multizone humidity minimum" The DB result viewer shows relative humidity up to 70%, so the system is not working. Error in...

If I want to use "Tools > merge zone > e.g. merge zones connected by selection", I can not see the whole screen. So i can not finish by pressing OK to save the changes, as indicated on the top of the screen. It's not possible to see the "OK button", neither is it possible to scroll down. Is there a ...

"lump similar windows on surface model" option was selected. I unchecked it and now it seems to work fine. In the manual you can find: Causes all windows on a zone surface having the same area, construction, frame/dividers, shading etc to be lumped into a single opening. However, it seems to have an...

Calculated natural ventilation: window area vs results

Suppose 2 windows with the same height, just right next to each other. Window 1: area +/- 1,35 m2 ; height +/- 2,7 m; width +/- 0,5 m (big window) Window 2: area +/- 0,27 m2 ; height +/- 2,7 m; width +/- 0,1 m (small window) I want to define an openable window area of 0,13 m2 for the small window.

Daylight map: window shading

Is it possible to generate daylight maps for a zone with and without window shading?
Activating different kinds of windows shading (always on) seems to have no effect on the map?
However, local shading seems to have the expected effect.

I want to simulate a building with a known infiltration rate 4,5m3/h/m2 at 50 Pascal. I'm working with Design Builder version 3. I can set the infiltration rate @ 50 Pa to 4,5m3/h/m2 under the Construction tab > Airtightness > Model Infiltration , but Design builder calculates with the crack templat...

Until: 12:00, 1,
Until: 24:00, 0;

by
