The heat pump in the image was designed to work only with fresh air. The red line doesn't make any sense to Design Build

DesignBuilder has some templates for different types of lamps (e.g. LED, T5, T8, incandescent etc.). Bear in mind that t

As far as i know the limit for maximum 50 thermal zones applies only to the trial version. Go to "Help / Licence" to see

you can find tutorials on youtube

If i have it in my Proposed Building i use it in the BREEAM Best Practice Building as well. Otherwise i don't use it.

I follow the same procedure - this implies 2 models for the Best Practice building. However, in GN25 the asterix sign *

From what i can tell the exterior temperature minimum is pretty high - this implies a lot of solar radiation as well. I

Go to the plenum and select it's floor. I'm guessing that the plenum floor has different layers than a regular floor.

can you share an image of your building (you can zoom in to the "problem" area)

Just make a 0.5m block between floors and assign it as plenum (Activity tab). After that verify the thickness of the flo

I never had this problem. Can you attach an image with the floor daylighting results.

I get your point and you are right, different curves should be used. Just for test - I have the same issue (water fed V

The simplest way is to go to "Glazing type", chose "2-Simple" definition method and at "Light transmission" enter the co

DesignBuilder shows only the PMV values in outputs. For the PPD values you'll have to use "DesignBuilder Result Viewer"

Make sure that the "Fresh air supply" box is checked in the simulation tab.

As far as i remember there is an option in the gains menu where you can specify the latent fraction.
