Igloo Culture Igloos were built by Inuit in the Canadian central arctic in addition to Greenl in addition to ’s west shore Used mainly as temporary shelter on hunting trips Larger semi-permanent igloos were also built that could house several families Design of igloos varies between Inuit cultures Igloo Physics A hemisphere is not a good dome shape Ideal dome shape is a catenary – Innuit design is very close to this ideal Height/Diameter = 0.3 as long as minimal stress But compression shrinking so it’s best to make H/D > 0.3 Theoretical maximum size of igloo is: D = 34 ft., H = 12 ft.

Igloo Physics A hemisphere is not a good dome shape Ideal dome shape is a catenary – Innuit design is very close to this ideal Height/Diameter = 0.3 as long as minimal stress at base But compression shrinking so it’s best to make H/D > 0.3 Theoretical maximum size of igloo is: D = 34 ft., H = 12 ft. More Igloo Physics Rate of heat flow through igloo given by where Q/t = heat flow per unit time, k = thermal conductivity, A = area of interior/exterior of igloo, Ti = interior temperature, To = exterior temperature, L = thickness of igloo Can calculate Q/t in the interior making simple assumptions about people Using reasonable values, temperature difference between inside in addition to outside can be about 60 C

Construction of an Igloo Snow must be packed Cut wedge shaped snow blocks using snow saw Lay blocks in helical pattern, cutting block thinner as you go up Dig a trough leading into igloo in addition to cover with snow blocks Terrace interior to so that inhabitants are elevated Cut ventilation holes Block laying pattern Construction of an Igloo Snow must be packed Cut wedge shaped snow blocks using snow saw Lay blocks in helical pattern, cutting block thinner as you go up Dig a trough leading into igloo in addition to cover with snow blocks Terrace interior to so that inhabitants are elevated Cut ventilation holes

Igloo Side View Igloos of the Future Building an Igloo in Hyde Park Problem: snow is not well packed Solution: pack it into buckets Problem: snow is cold in addition to not fun to touch Solution: buy a shovel Problem: people throwing shit at your igloo Solution: none

The location: 60th in addition to Drexel Igloo Nick STAGE 1: COMPLETE

The Finished Igloo!
