The proposed design had several new additions. The North wall was pierced with four new windows and a horizontal shading device. The east widows and wall received a three foot horizontal overhang over the length of the entire wall and 2 foot vertical shading devices 18 inches on center. The West wall received a 2 foot horizontal overhang the length of the entire wall and 18 inch vertical fins 1 foot on center along the upper windows.
The indoor temperature with added shading devices reduced the highest indoor air temperature by around 2 degrees and the average indoor temperature by around 2.5 degrees.
Peak total loads were also reduced form 30.75 to 22.43 KBTU/Hr. This would reduce the energy required to cool the lounge in the summer months.
This chart shows the heat gained by adding skylights. The proposed skylights did show some heat gain in the summer months but not a significant amount. It appears that using daylighting would be beneficial. Click here to see a computer generated model of what the lounge would look like with skylights.
The average KBTU/HR dropped from .45 to .37. This is the result of using 2 foot vertical fins 1 foot on center. to shade the openings. A 3 foot overhang was also used for shading.
The East window Peak KBTU/Hr dropped from 40.67 to 27.01 with the addition of shading devices alone.
The average KBTU/Hr went from -.51 to 0.41 in the West wall. Shading devices are in place in the proposed design. The data doesn't seem correct so further investigation must be done.
With the addition of shading devices the calculations went up from 9.29 to 9.43 KBTU/HR. Adjustments need to be made here.
No windows existed on the North wall in the original design.
The North window gained most of its heat from 3 to 6 p.m. in August. Two foot overhangs were used to shade these windows.
