The thermal conductivity of snow varies by how tightly packed it is, but for snow of 100 kg/m3 density ,it is about 0.045 W/m/°C or 0.026 Btu/hr/°F. A half foot snow will this have an R-value of 19. A typical igloo is about 12ft to 15 ft in diameter ,and so it has a surface area of about 300ft2 .(We will ignore the floor.)igloolik ,Nunavut, Canada requires about 20,000 degree days (Fahrenheit units) for a typical year .Calculate how many kilowatt hours you would need to keep your igloo cozy
