The VELUX Building Simulation Tools are validated (accurate) simulations tools to investigate the effects of adding windows on the daylight, thermal comfort, air quality and energy performance of buildings.
VELUX Daylight Visualizer helps professionals by predicting and documenting daylight levels and appearance prior to realization of the building design. An intuitive modeling tool permit quick generation of 3D models and users can import 3D models generated by CAD programs in order to provide flexibility to the model geometry.
VELUX Energy and Indoor Climate Visualizer is used to evaluate the performance of single-family houses with respect to energy, ventilation and indoor climate. It focuses on windows and solar shading, and their effects on the energy consumption for heating, ventilation, cooling and lighting. It has flexible control options for natural ventilation and solar shading.

How do you speed up your simulations? I have very fast computer, but simulation takes more then 16h, when i want to do 1 year simulation for advanced level?
Sensor points can be used with imported models only and need to be generated by the user. It can become quite intricate for complex spaces and larger buildings - where the “zone” workflow can make more sense. Take a look at this tutorial ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hm_mhia0_Gc.html
9:53 I noticed that the surface area of the facade windows are smaller than the dimension dictate. I suspect a certain amount is allocated to window frame. Is this controlled or specified somewhere?
@@VELUXsimulationtools The project properties show the total glass area, but not the dimension of frame. However i might have figured it out. All facade windows have a frame of 100 mm (5cm on each side also sound reasonable) I noticed that e.g. a window of 200 mm x 1100 mm have area of 0,1m^2
I have assigned the materials to my building as instructed but when it is imported to VELUX the assigned building materials don't appear, only the zone materials. What should I do to fix it?
I am having problems exporting the report. When i save it one mye desktop it opens in my webbrpweser as a broken link. Do you have any idea why this is?
Why do one adjust the output area, and make it smaller? Does it calculate anyway with buildings or other things outside the smaller output area that you have chosen? And the calculations go faster?
Thank you for making such useful tutorial. I would like to ask if we can anaylize daylight distribution for existing buidling consist of atrium. Is Velux Daylight Visuallizer relaible and accurate for such analysis. I am doing research on " The effect of atrium size on daylighit distribution of a buidling" Also can we import revit model into Velux. I would be really glad if you answer my question. Thank you
Hi! In my render the light coming from openings is black and everything else is black, it looks like an inverted image. Also there is no slab visible in my model I imported from sketchUp, which I suppose is the cause of the problem. How can I fix this?
Hi Harsh, your model needs to be well closed and daylight transmitted through window glass. The program needs to know what is the interior vs exterior. With illuminance renderings the window glass appears black because they are light emitting sources and illuminance measures light received on surfaces.
The video shows both renderings from Daylight Visualizer and pictures from the realized project. The renderings are tagged with Daylight Visualizer 2 and the pictures with the photographer's credits.
