Carrier E20 hap software atrium heat load calculation. 1

[sefabozkurt]

I have a atrium (half pipe glass roof).Software wants only two dimension for skylights.If I use only to dimension ,roof area will be projected area and will be less than actual glass area.(In my problem there is %20 area difference).If I use actual glass area ,This gives also wrong result because solar radiation area is the projected area.Which area must I use.Thank you in advance

if you are simulating a "half-pipe" you should have an area of vertical glass that would be input as two glazed walls. Then under your roof option you can input 4 roof types per space, each of the four types would be input at varying angles to approximate the smooth curved "half-pipe" shape. Each roof type would have a skylight associated with it.

This should give you a reasonable approximation for your system geometry.

Thank you walkes for your pointing me correct direction.My roof loads increased 10 percent after assumed my roof as a 4 piece. B-) B-)
