Methodology
Approach:
  • The first step in proving our hypothesis was to get a baseline measurement of the illuminance levels within our space. In order to do this, we used the digital illuminance meters at two different times of the day. Our measurements were taken at the large table in the center of the reading room at each chair location. This is where the majority of the students would be affected by the luminous environment conditions. Secondly, measurements will be taken at the book stacks along the perimeter walls for those researching and book finding.
  • For the daytime analysis, we will be recording readings with opened and closed shades to compare the influences that these controlling devices have on the study conditions. This will prove that the user shading elements are sufficient enough to control the daytime environment.
  • During the evening hours our study will focus on the existing luminaire power output/direction. Further analysis could suggest the introduction of new portable desk-top luminaires.
  • All measurements will be recorded in foot candles. Our overall goal is to convert our foot candle recordings to Lux, thus requiring us to multiply by 10. We will compare these readings to the "appropriate" levels as stated in Mechanical and Electrical Equipment for Buildings (M.E.E.B.) to determine the range of illuminance that is specified to be "comfortable". In addition, the Illuminating Engineering Society (IES) handbook will be used to calculate and prove insufficient electric lighting is currently provided within the study space per square footage.

Form Z, the 3-D modeling software will be used to propose new lighting conditions in the later portion of our case study.
