Hi,

Any chance of getting a "horizontal sky component" checker?

Im doing a lot of sun lighting assessments and can only perform the vertical sky component for vertical windows, however, im seeing a lot of skylights which require analysis lately.

Hi,

Can anyone tell me why i get a different VSC answer every time i press run?

Answers are always within 5% of the previous answer. Is it something to do with accounting for a human error. When carrying out a manual VSC calc using a skyline indicator and counting up the dots, you could get two ...

Hi,

Juts wondering if there is any way to display numerical figures for the amount of % exposure within suncast analysis. As it stands i can see a coloured graph which would give an idea of the numerical number but not the actual figure.

What im doing is setting it to show values above a certain ...

Hello All,

Im carrying out a daylight and sunlight study in line with BRE's document Site layout Planning.

Part of the criteria is for amenity areas to receive 2 hours of sunlight on 50% of the garden during the equinox.

In the ...

Hello All,

Quick question with regards to modelling spandrel panels.

Mu understanding is that it should be modelled as a door with the construction make up similar to a wall.

Alternatively, could it be modelled as a window?

Only issue is that a spandrel panel does not have a g-value or VLT.

To ...

Hi I am currently carrying out the same simulations.

<My understanding is as follows.

Set up the model for a full dynamic simulation i.e.

Internal gains, heating, cooling, ventilation etc etc

Are you are looking at PMV and PPD??

If this is the case go to "vista" to view your results from the ...

Hello All,

My situation is as follows.

I'm carrying out a thermal comfort simulation by finding out air temperatures in spaces and to see if they fall within a specific range. i.e 21-23 degrees.

I'm running for both summer and winter conditions. I'm having no issues with the winter condition so ...

Thanks brilliant,

Thanks for your help!!!!

Hi thanks for the reply,

I have set the angle to 20 degrees.

So do i have to play around with the angle to get the desired velocity?

I cant actually specify a discharge velocity in the "boundary condition" dialog box.

I can only specify on the bottom taskbar

The reason for the analysis is to ...

Hello All,

I'm having an issue specifying my flow rate and velocity for a diffuser.

So my design is as follows;

A 600mm x 600mm supply diffuser with a flow rate of 0.21 m3/s.

Using Q = V x A this gives a velocity of 0.21m3/s / (0.6 x 0.6) = 0.58m/s

So I draw my diffuser on my ceiling as 600mm x ...
