Vital Signs Case Study

******************** Methodology ********************

The methodology used in the case study was as follows:

Distribute questionnaires in the computing center - (see questionnaire below)
Use the LiCor Quantum Radiometer/Photometer (with Pyranometer sensor) to determine the light transmittance of the two window shades. The solar radiation through only the glass window will be measured, as well as the solar radiation through the window and shade combinations. It will then be possible to determine what percentage of solar radiation is reduced by the introduction of the mesh shade and the solid shade, respectively.
Use the Minolta digital Light meter to measure the illuminance levels throughout the room. One measurement will be taken in each row, on the desktop surface, under the following shading conditions:
- Shades open
- Mesh shades closed
- Opaque shades closed
and the following weather conditions:
- Sunny
- Overcast
- Night
Subjectively evaluate the glare conditions under each of the previous conditions. This will include a common comparison of the screens to one another, as well as an intuitive evaluation of the extent to which the usability of each screen is impaired by glare. In other words, we will see how easy/difficult it is to read and view information on the screen from common computer applications.
Discuss design intent with Project Architect.

Architectural Case Study Survey

1. On the following diagram, please circle the computer at which you are seated.

2. What time of day is it?

3. What are the outdoor lighting conditions?

a) Overcast b) Sun c) Rain d) Night-time

4. Please glance behind you to the windows. On each window there is a solid and a mesh shade. On the diagram below, mark the levels of the shades: M for Mesh shade and S for Solid shade.

5. Are you experiencing any dissatisfaction with the lighting in the room?

Please mark all that apply:

_____lighting is too bright

_____lighting is too dim

_____glare on the computer screen

_____room is too hot

_____room is too cold

6. Please write any other comments on the usability of the computer lab.
