SRG has run into a problem with the current LEED V4.I when it comes to achieving daylighting credits for mid-rise buildings in the Pacific Northwest. The higher in latitude a structure is on the globe, the less potential sunlight will reach it. In order to calculate how much sunlight enters a space we partnered with SRG to create a tool to help determine how much usable daylighting enters a space. From this tool, we want to collect data from different latitudes to show discrepancies in the possible daylighting conditions in these locations, and then finally organize this data in a meaningful way that can be used in the lighting design phases of future SRG projects.

Standard Daylight Autonomy
Standard daylight autonomy is a measurement of determining if a space is suitable for human occupancy over an extended period of time. The hope is that if a space is well lit, then it provides a healthi­ er experience for the human occupants who use the area for extended periods of time. It is typically used for working in office settings, because individuals are usually stationed in a single place for an extended period of time, standard daylight autonomy is calculated by measuring the percentage of floor area that has workable lighting during fifty percent of the work day.
