WINDOWS:

You can from following charts see movement of the sun on the sky through the year so we are able to count shadows  and design the slope of  front glass face. Angle of elevation is from 16.6º (22. December) to 63.4º ( 21. June). Angle of windows will be 70º.

THE NAUTILUS>>> Water management

Rain-fall in Czech republic in year [mm]:

water consumption in Earthship  (one person):

Toilet——————————————————- 0 l

(water is recycled)

Shower—————————————————- 32.5 l

(6.5l per minute x 5 minutes of showering per day)

tap water————————————— 11,5 l

(cooking, cleaning ….)

Hand dishwashing———————————- 7,5 l

Washing mashine—————————————————- 10,6 l

(en. class A++, 37l x 2 washing / 7 dní v týdnu)

TOTAL… 62,1 l

2 people in The Snail will need about 124,2 litres per day, 45 333 litres per year.

MNOŽSTVÍ VODY CHYCENÉ STŘECHOU ŠNEKA:

Surface area of  the roof : 110 m²

year average rainfall in area (Hradec Králové ) is 592 mm

minimal  year  rainfall in last decade ( 2008 ) :  465,7 mm

>>> one meter square will catch about 0,592m³ (592 l) in year

>>> The snail would catch  (110m² x 592l) 65 120 litres of wather in year

>>> The snail would catch in  very dry year 2008  (110m² x 465,7) 51 227 litres

SIZEING THE CISTERN:

Inspired by dryest years in an area (1999, 2003, 2008),  I imagined bad data and simulated swinging of water level in the cistern throughout the year (expecting consumption suggested before)
