1
importing 3D CAD Geometry import / *.dxf/ choose file/ zone > by item name/ scale objects by: metres > milemetres
select all objects/ modify/ merge coincident triangles fit grid to objects
2
shadow display load wather file/ locate weather file > Berlin, Germany. shadow settigs /[activate] daily sun path 足 annual sun path_show shadows only/ shadow range > show shadow range & activate/ show solar projection
3
solar access analysis a. all objects (buildings) select all objects calculate > solar access analysis/activate: incident solar radiation for specified period [april 1 to september 30] cumulative values objects in model >only use selected objects perform detailed shading calculations surface sampling [low 1 pt (centre)] sky subdivision [low: 10* x 10*] use fast calculation method ok
b.
grid right menu > grid/ display analysis grid auto fit grid to objects/ grid management/ number of cells > x: 30; y: 30 calculate > solar access analysis/activate: incident solar radiation for specified period [april 1 to september 30] cumulative values analysis grid (insolation only) perform detailed shading calculations surface sampling [low 1 pt (centre)] sky subdivision [medium: 5* x 5*] use fast calculation method ok
c.
object [building facade] select 1 object [building facade]/ modify/ surface subdivision/ rectangular tiles/ offset from surface: 足1/ ok select the new surface calculate > solar access analysis/activate: incident solar radiation for specified period [april 1 to september 30] cumulative values objects in model >only use selected objects perform detailed shading calculations surface sampling [low 1 pt (centre)] sky subdivision [low: 10* x 10*] use fast calculation method ok
first facade wasn`t to good. so I repeated the process with a nwe one
4
spatial visibility analysis select volume [all abjects]/ calculate > spatial visibility analysis/ visibility of selected objects/ next/ suggest a reasonable sample size/ ok
5
wind analysis wind analysis software is required edit the grid manually/ Blockagcs: Covered in Z 足 Wind Settings: Speer: 8.00 m/s; Direction: 40 足 run WinAir Aplication, Auto足Start Calculation and Equalise Air Flows must be active/ OK save de file in C:/ go to calculations/ Load OutPUT File.../ go to C: and load OUTPUT file. you can choose to visualize different kind of analysis_ air flow rate cell presure flow vector cell temperature
