Assignment 1 - Plan & Section

The above chart illustrates the light tactics that need to be considered when designing.

My current office is located in downtown White Plains on the 7th floor of an 8 story building. The work stations are located on the south side of the building and currently gain plenty of daylight. Shading devices are not provided and could be utilized in the summer and early fall months. The work spaces are located in the first 19'-6" of a 45'-0" wide building. The northern side of the building contains a few work stations but mostly printing and model making stations.

In order to determine the number and head height of windows necessary to achieve the desired daylight factor the above chart and following calculation were utilized:

Head height requirement:
19.5' (depth of room) / 2.5 = 7.8'

As a general rule one can utilize the 2.5h day lighting guideline which means that calculating 2.5 times the head height of your window will result in the floor area covered by the daylight.

Horizontal light penetration:
4' (width of window) x 2 = 8'

The required area of daylight apertures for the work space:
A= (0.050 DF x 19.5' depth of room)/(0.2 target of average DF)= 9.75 SF

The square footage of the apertures are 24 SF

These drawings demonstrate the day lighting techniques utilized the the fall in NY. The windows will need adjustable shading devices due to the lack of need of them during the winter and spring months. I have demonstrated adjustable shading devices in this drawing but deciduous planting could be utilized as shade devices as well. The zones are also indicated on this plan as to their DF requirements and the 15/30 guideline. Task lighting will need to be provided at each desk for optimal lighting coverage in the work zones.

After the phone conference with my affinity group tomorrow night things are likely to be revised. Look for changes after tomorrow evening.
