Re: [TRNSYS-users] radiation and shadow, type 56

Karol,

No this is impossible.

However, the bui files aren’t the same, especially the geometric part of the Mnr8_sh contains only geometric information of 2 zones

BATHROOM and HALL.

Also the calculated volume isn’t the same.

It looks like all the zones with the GEOMODE=MIXED are missing. How did you create shading file?

I repaired you shading file concerning the geometry. Are the results now ok?

Best,

Marion

Betreff: radiation and shadow, type 56

Dear All,

I have two .bui files of the building. The first file is assumes that there is no buildings next to consider one( Mnr8), the second file contain shadow zone of surrounding buildings (Mnr8_sh).

The energy demand are higher for version with building shadow zone –it seems OK. But I am looking for solar radiation that reach building windows in each case, so I use NTYPE 69 or 74 (it is ok???). And the problem is that the building with shadow has higher values of those NTYPE then the building without shadow. How it is possible???

I will be grateful for any hints!

Regard,

Karol
