Passive solarAt the south we decide to make solar window..Why??

* Because solar chimney is not effected as shown in calculation Passive solarSolar chimney calculated: A = 4 ft2T1-T2 = 30 F in winterH = 18 ft.Q= 540*A*h (T1-T2) = 540*4*18 (30) = 50193.86 ft3/ hr.Volume of space = 9486 ft3

Number of change = Q/ V =50193.86/9486 = 5.2 change/hour and that less than 6 so the chimney not efficacy in the house ,Shading :

Sample calculation:

Design the horizontal lover in the 21/5 at 12 pm

X = h/ (tan (Alt))

X= horizontal length of lover

H = glass height

Alt =Altitude at 21/5 at 12 pm and equal 78

So the first design for h = 40 cm and y = 0

X = 0.4/ (tan (78)) = 9 cm

And anther design for h = 120cm and y = 0

X = 1.2/ (tan (78)) = 25cm

Quantity and comparison: Divide into two types : 1- cost without using alternative materials with area equal 350 m 2 (former design) 2- cost after revised and using alternative materials with area equal 354 m 2 (revised design)

Conclusion: Using the alternative materials, external stone, PVC windows, doors, fiber hollow block in the internal wall and PVC floors tiles, reducing the total cost about 21%, with the same or best efficiency than the local material.
