This page describes all calculation and assumptions in calculating Kauffman art center retrofit the top roof


Method[edit | edit source]

To measure hatched area in Fig. 1 Google Earth distance measurement has been used.

  • All measurements repeated three times and averaged to minimize the error.
  • Google Earth distance measurement tool does all measurement as level plane. This measurement is not accurate for inclined planes like roof.
  • to minimize the error angle of the roof was measured and considered in calculations (Fig. 2).
  • Top right and left red hatched area in Fig. 1 considered as triangles
  • Bottom right and left red hatched area in Fig.1 each estimated to a half circle

Area calculation of top right and left triangles red hatched in Fig. 1[edit | edit source]

  1. top left:
    • base= 63 m
    • leveled length (Google Earth)= 31 m
    • inclined length (considering 45 degree angled) = 43.84 m
    • Top left area= (63 m)*(43.84 m)/2 = 1381 m^2
  1. top right
    • base= 45.2 m
    • leveled length (Google Earth)= 27 m
    • inclined length (45 degrees) = 38.18 m
    • Top right area= (45.2 m)*(38.18 m)/2= 863 m^2

Area calculation of bottom right and left half circles red hatched in Fig. 1[edit | edit source]

  1. bottom left
    • diameter=30 m
    • half circle area= (pi*15^2)/2=350 m^2
  1. bottom right
    • diameter=39 m
    • half circle area= (pi*19.5^2)/2=597 m^2

Total red hatched area in Fig.1[edit | edit source]

Total area= 1381 + 863 + 350 + 597 = 3191 (m^2)
