El Corte Inglés at Placa Catalunya is optimized by a responsive sun screening system in order to regulate  the solar gain, reducing it in summer, while maximizing it in winter.

The sails’ width and their movements are based on the sun study of the location, respectively annually and daily.

    PSEUDO CODE
  • CREATED SURFACE FROM OFFSET OF BUILDING FACADE.
  • CREATED A RADIATION ANALYSIS WITH LADYBUG PLUG-IN, BOTH ANNUAL AND DAILY.
  • EXTRACTED CENTER POINTS AND NORMALS OF FACES OF RESULTING MESH.
  • CREATED LINES FROM MESH CENTER POINTS  WITH LENGTH DETERMINED BY RESULTS OF AVERAGE ANNUAL  RADIATION ANALYSIS.  
  • INTERPOLATED STARTS AND ENDS OF THESE LINES AND LOFTED RESULTING CURVES TO CREATE AWNING FORM.
  • ROTATED LINES ALONG THE Z AXIS WITH DEGREE DETERMINED BY A SECOND DAILY RADIATION ANALYSIS.
  • CREATED POLYLINES FROM MESH CENTER POINTS AND PIPED LINES TO CREATE THE FACADE SUPPORTING STRUCTURE
  • FINAL STRUCTURE RESPONDS TO THE THE HOUR OF YEAR PARAMETER TO OPTIMIZE SOLAR GAIN OF BUILDING THROUGHOUT THE DAY.
